According to the International Electrotechnical Society (IEC) in 1995, developed Aspire 1410 battery management system standards, and electric vehicle battery management system must have a certain battery diagnostic functions, including unhealthy cells and to provide early warning information on the battery aging. During these 10 years, major foreign companies conduct a vigorous research studies, and in its operation using the battery management system by adding a certain amount of battery diagnostics. One representative of the company, and Mentzer Electronic GmbH in Germany, led by Werner Retzlaff designed BADICOaCH system; U.S. Aerovironmevt developed SmartGuard System (Long - Life Battery Using Intelligent Modular Control System).

(1) BADICOaCH System

BADICOaCH system is BADICHEQ system improvements, it has a battery diagnostic-related functions: on the recent 24 charge-discharge cycles to store TravelMate 4500 detailed data and allow good and bad judgments on the battery when the battery quickly find basic information and errors are used;

(2) SmartGuard System

SmartGuard system has a battery diagnostic-related functions are mainly to provide reverse polarity alarm and battery discharge history and archives.

Domestic battery fault diagnosis also has certain research, such as Chunlan Research Institute, Tsinghua University, but most of the research is still in its early stages.

In this paper, the battery fault diagnosis study is to find fault with the LCBTP03003 battery cell performance parameters to one or the relationship between N, through real-time monitoring, comparing the same battery of different parameters between single cell changes and consider some other factors to carry out a comprehensive diagnosis. After years of study, has concluded with a pre-feasibility study of algorithms and experiments in electric car sports car for battery diagnostics. His thinking is the same one every single battery charge and discharge the battery at the same current, the majority of each single cell performance was similar, but there are some inconsistencies in the performance of the battery. Through an integrated consideration of various cells during this time, on the average voltage offset and various battery voltage during this time period can be estimated changes in battery performance is good or bad. Small and single-cell voltage offset voltage change is relatively small, A42-A3 good battery performance. Because there is no failure was the performance of a battery charging voltage increase for the slow discharge voltage drops slowly.

1 Introduction

With the continuous development of the national economy, energy, electricity, transportation, telecommunications, environmental protection and other areas of modern demands are rising. As a back-up battery system of energy is being used in large quantities does not allow power-off of all of the power supply systems, battery is an indispensable backup power systems. Moreover, the battery system in various industries more and more widely applied. Battery operating status is normal, TravelMate 290 a direct impact on applications in a variety of equipment, normal, reliable and safe operation. In particular, unmanned site and e-commerce center, bank back-up battery becomes particularly important.

After testing and optimization of the battery group in each monomer battery performance differences still exist between, these differences in the long-running process of the battery due to small differences in the environment (such as the temperature difference) to varying degrees to generate new differences. After a long run, individual battery performance decreased significantly, seriously affect the battery performance, or even result in accidents, and requires early diagnosis of single-cell performance degradation and early failure. In addition, the single-cell performance degradation and failure will reduce the battery's SOC (state of charge) value, because poor performance of a single battery power determines the battery's state of charge. A battery is normally provided by a number of single TravelMate 4000 cell or battery modules in series; performance of the backward single battery may cause early termination of the entire battery discharge. And therefore need to be equipped battery fault diagnosis expert system. Through the diagnostic system to achieve the battery failures and risks of early warning, so that it can effectively increase the electric vehicle battery pack driving range and trouble-free working hours, so to minimize the maintenance workload, thus ensuring reliable operation of electric vehicles are able to.

Electric vehicles in whole or in part from the energy storage battery. Constrained electric vehicle technology development and industrialization of electric vehicles as a major problem is energy storage cell and its application. Battery in the use of a prominent issue is the difference between the various cells, there are inconsistencies, so early detection of inconsistencies and faults the TravelMate 2300 battery has become very crucial technical challenges. Need to develop a battery of early fault diagnosis system. Through expert diagnosis system, we can achieve the early diagnosis of unhealthy cells, but also so that the remaining capacity estimation model can be more accurate, this can extend the battery life and further reduce battery costs and increase the driving range of electric vehicles to improve vehicle drive reliability. The system and technology research has theoretical value and the promotion of electric vehicles, industrial significance. Aspire 1680

Economic Information Daily: low-carbon era of strategic transformation of China's energy

Energy transition is the key to the country's economic restructuring, but also an important symbol of social progress. laptop battery To achieve low-carbon technology, and ordered the energy structure is the fundamental positioning of China's energy strategy.
China's energy efficiency, pollution is serious, to some extent is not due to insufficient technical strength, but because of institutional unreasonable and caused by the imperfect market mechanisms. Technological innovation to support industrial development of the institutional lack of rail, allowing a large number of clean and efficient energy technologies are not widely used.

Energy is "industrial food" or even "the blood of modern industry", but continued to release a huge external impact. Energy tremendous impact on the environment, even more than other industries. In China, the coal industry, oil, thermal power and other traditional energy development and utilization have been carrying the miracle of China's economic take-off for nearly 30 years,M6091 but also a great extent, affect the survival of our natural environment to their homes.

Therefore, the energy structure to the direction of diversification and balanced development of both a strategic transformation of the core issues of energy, but also macro-economic strategy towards sustainable development in the direction of rational choice. In December 2009 Central Economic Work Conference held in clear will "to adjust economic structure," one of the tasks included in the 2010 six.

Of "coal" in China's energy structure of

Occurrence of the characteristics of resources, a fundamental decision to maintain our long-standing "to coal-based" structural features of energy consumption.

In 1952 compared to 2008, China's primary energy consumption of coal increased from 95% down to 68.7 percent, oil consumption increased from 3.37% to 18%, natural gas consumption increased by 0.2% to 3.8 percent, hydropower, nuclear and wind power in the energy consumption structure in the proportion of from 1.61% to 9.5%. Acer Laptop Battery

Is basically the same structure of energy production. Among them, taking of the absolute percentage of traditional energy, particularly coal production since 2002's eight years in the energy production structure in the proportion has remained at around 76%; followed by oil, China's crude oil production in the structure of energy production 12% of the basic level. In the secondary energy, regardless of the consumption structure or the structure of production, and basic to coal-based thermal power-oriented energy.

Overall, China's energy production and consumption, showing a "rich coal, short of oil, less gas," and "new energy shortage," the structural characteristics. Clearly, this low calorific value of fossil fuel-based energy structure, the negative externality the more significant impact on the environment.
Development Trend of China's energy diversification BTP-43D1

The trend of China's energy diversification is currently manifested mainly through three scenarios:

The basis of the formation of multi-energy system development trend

Through the promotion of natural gas, coal-bed methane gas and other clean energy sources by leaps and bounds, the promotion of energy system from the "coal-based" structural features to the "oil, and gas equal emphasis on" transformation. This is the "Eleventh Five-Year" during the transformation of China's energy system, an important direction, but also the basis of China's energy system to achieve diversification strategy, the inevitable choice.

China to open "gas energy" Time has a good resource base. At present, China has proven natural gas reserves of 2.6 trillion cubic meters, is expected to be recoverable reserves of 7-10 billion cubic meters. At the same time, China's coal-bed methane resource-rich, is the most inexpensive high-quality coalbed methane resources in the reserve country. The latest survey results show that resource: our depth of 2,000 meters in the shallow geological resources of coal-bed methane total of 36 trillion cubic meters, of which recoverable reserves of 10 trillion cubic meters, TravelMate 220 ranking third in the world.

Clearly, China has met the land in accordance with Tuohai an independent supply of gas energy to push the gas energy by leaps and bounds have been prepared with a sufficient resource base and transition conditions.

Multi-level, low-carbon energy structure, showing the pattern of

Founding 60 years, with the national economic and social development, particularly in the promotion of technological progress, China's primary energy consumption structure, from the sound to achieve the "coal" to "equal emphasis on oil, and gas," the change, while the new energy, the proportion of renewable energy sources there are also improved significantly.

Comparison of the energy mix in 1952, as of 2008, China's primary energy consumption of coal increased from 95% down to 68.7%, oil and natural gas consumption accounted for 21.8%, hydropower, nuclear and wind power are clean and can be the proportion of renewable energy is close to 10%. BTP-58A1

Although the future energy situation, there are still many uncertainties, but China's energy consumption structure is being fully diversified trend.

Recently, the State authorities are working on a new "energy development Shier Wu plan." It is understood that the proposed "new energy industry planning", requiring "Shier Wu" planning period, the new energy sources the proportion of total energy consumption from current levels to around 12% -13% by 2020, new energy the proportion of the energy structure will reach 15%. Will be wind power, solar power and nuclear power generation installed capacity targets in large-scale restructuring, which will have a tremendous new energy industry a boost.

Has been initially achieved in the industrialization of new energy and renewable energy sources, solar and photovoltaic energy development extremely important. China has become the largest producer of solar cells, as at the end of 2008 China solar cell output reached 1000M W, ranking first in the world. Solar cell production in 2009 reached 2800MW,BTP-60A1 and the development and use of space is still enormous. In addition, the revitalization of nuclear power has also become the focus of the new era of energy diversification.

Energy development strategy for the formation of regional diversification

In recent years, China's energy development, not only the formation of the layout of the domestic development of a diversified pattern in the international energy development, has gradually formed a strategic layout of the diversified investment and development trends. Energy development in diversified, moving from home and abroad by domestic development to simultaneously speed up the development mode shift.

China's "a shortage of oil and gas resources are relatively rich in coal," the resources of occurrence status, fundamentally determines that China's oil (601857) industry from the past "by relying on domestic development, relying on foreign imports" model must be broken, especially in the oil more to more seriously affect the national security today, China's oil industry have a historic change: "from the domestic development model to accelerate the changes in domestic and international development simultaneously." TravelMate 240

With the continuous expansion of the international strategic space, China has been actively involved in international energy resource market, the "collective chorus" in. At present, China's energy field of international cooperation from the original oil-and gas-based, and gradually extended to natural uranium, coal, electricity, wind energy, bio-fuels, energy technology and equipment and other aspects; Up to now, China has 36 countries have established mechanisms for bilateral energy cooperation.

In addition, in recent years, through wholly-owned, joint ventures, equity participation, M & A, etc. in a flexible manner, China's energy companies in overseas energy resources exploration, development and utilization has carried out fruitful cooperation.

The transformation of China's energy strategy objectives

From a strategic point of view, the energy challenges facing our country no more than two dimensions of the contradiction:

First, the limited energy supply and economic development in the growing contradiction between the energy demand. This is an economic issue, requires that we must think about how to carry out system design and effective implementation, "to limited energy to meet the sustained and rapid economic growth." BTP-52EW

Second, large-scale use of energy and environmental situation in the contradiction between increasing. This is a social problem, we are required to balance the economic needs and choose a combination of social objectives, we should be "as much as possible to reduce or even avoid the energy use during the environmental damage and social welfare loss."

Face its energy challenges, countries not only at the macro level or the micro level, have put forward the scientific concept of development in accordance with the requirements of energy and resources into economic growth, that "energy-saving emission reduction," the effective use of resources to the call, while the legal development of a family-related economic laws and regulations by the law and the energy sector high consumption, high pollution from the source has played a powerful role in binding.

To this end, in recent years, China's energy sector have taken place in the following areas quietly strategic transformation and development of changes:

By the high cost of extensive use of energy to change the mode of intensive use of energy

With the rising level of China's market-oriented, market-based mechanism gradually healthy economic growth depends on the plan being developed by the extensive reliance on market-based model to the intensive paradigm shift. In this historical trend under the guidance of government in economic management concepts and methods have undergone tremendous change, BTP-63D1 particularly in recent years for the development of the industrial structure optimization and energy industry issued a series of policies, not only a strong impetus to the level of the state's industrial upgrading and changes in the high-energy-consuming industries has been contained, but also to the energy industry into a collective energy-saving emission reduction track.

In particular the coal industry base construction and resource barriers to the establishment of firm size, so that the size of the coal industry structure tends to be improved so that energy efficiency greatly improved. Recently, more controversial is the integration of coal resources in Shanxi Province, showing a "dilemma" situation: the size of energy conservation is to improve the protection of the environment, or the country back into the China challenge of property rights, fair market issues. In fact, from the energy industry, in essence, need to improve the degree of concentration of the coal industry, with the necessary scale of it must be saved, and the use of an efficient institutional arrangements and the establishment of a strict economic order, through the rules of the market to achieve the goal of energy to improve the is important.

In addition, the promotion of energy conservation and energy BTP-42C1 efficiency aspects play a role in promoting technology innovation, equipment and technology to achieve leapfrog development, promote energy productivity "great liberation." Development today, China's mining processing in the energy, electric power transmission and distribution technologies, energy conservation and energy efficiency technologies have made historic strides, and tackled a series of technical difficulties, the construction of a large number of domestic equipment, has developed a large number of domestic equipment, master and build a series of energy theoretical system.

By the negative externalities of non-clean energy development and the shift to clean energy technology

China's energy efficiency, pollution is serious, to some extent is not due to insufficient technical strength, but because of institutional unreasonable and caused by the imperfect market mechanisms. Technological innovation to support industrial development of the institutional lack of rail, allowing a large number of clean and efficient energy technologies are not widely used.

In this regard, from the "15" later, the state attaches great importance to clean energy development, has introduced the "Clean Energy Production Promotion Law", "Renewable Energy Law" and a series of clean energy policies and regulations, "Recycling Economy Law" is also being promulgated in the brewing. In recent years, with the rapid development of the national economy and social development has improved continuously, the whole society an increased awareness of environmental protection, and in the national economy in all industries, especially the energy sector received very positive response, so that the social development needs of clean energy the environment has changed significantly.

In our national economic and social development "Eleventh Five-Year Plan" for the first time to our country's energy-saving, environmental assessment and indicators of economic growth, triple-bound quantitative constraints, clearly pointed out: by 2010, should be "per capita gross domestic product value is more than double that of 2000 "," unit of GDP energy consumption reduced by 20% or so ", and" the total discharge of major pollutants reduced by 10% "and so on target. Today, the "post-Copenhagen era," the pressure that global carbon emissions in the "Shier Wu" period of carbon emission reduction as the core of environmental issues more important than ever, Premier Wen Jiabao at the Copenhagen Conference of the solemn commitments have been fully BTP-44A3 demonstrated: Environment The problem is the top priority for future development.

Low-carbon technology is a general trend. The energy industry as a high-carbon industries, particularly in China coal-based energy system, its carbon dioxide emissions is "persistent" problem, therefore, China's coal-based energy system can only be a fundamental change to the "Clean of low-carbon-based "road.

By non-market-oriented transition to a market-oriented goals

Overall, comparing the size of China's economic and social development level, China's economic system and the level of the market mechanism is still relatively lagging behind. It has been decided, China's energy market reform is mainly embodied as follows: market-oriented price formation mechanism as well as the energy capital of the depth of two ways.

First, the price reform. In the energy sector, the price issue has always been a sensitive issue will affect the situation as a whole. In particular, the price of oil and natural gas industry, long-term reliance on national administrative control. In fact, China's oil and gas price formation mechanism is still self-contained. Market-oriented reforms in the price, go faster should be the field of coal and electricity. After 10 years of gradual reform, the coal market price to the government in early 2010 and complete exit; coke is close to opening up the market prices; and people's livelihood of the most sensitive to the market price of electricity, but also social development, according to changes in the new situation of the initial achieved a market-oriented. BTP-550P

Second, the energy capital of the issue. Grafting of modern energy enterprises in the capital of the developed platform is its realization of institutional innovation and rapid route to development. At present, China's three oil giants energy companies, PetroChina, Sinopec and CNOOC (Quotes, information, reviews) has been achieved in various locations around the world available. As of early 2009, listed companies in the coal industry is about 40-50 at home, its total market value reached more than 1 trillion yuan. In addition, the electric power sector companies are also 50-60 at home, its total market value of nearly 6,000 billion yuan. Through the realization of market, oil, coal and electricity industry concentration significantly increased significantly improve our ability to compete.

In the international market, through the capital market resources, the overall expansion of China's energy industry practice of "going out" strategy, a more distinctive features. Since 2006, the SASAC published overseas investment strategy of the three oil companies since the expansion of the energy sector the focus of international capital has penetrated into all the world's oil-rich regions.

In short, low-carbon technology is a global trend, but also Chinese targets. Energy transition is the key to the country's economic restructuring, but also an important symbol of social progress. Therefore, a low-carbon technology, and ordered the energy structure is the fundamental positioning of China's energy strategy. BTP-73E1

Electric vehicles have no electricity and how to do? To the gas station for the battery on the line!

You will buy electric cars? Asked about this issue, many people would hesitate: open open how to do without electricity? M8511 If the battery is what is broken, will not spend a lot of money? JAC Technical Center Co., Ltd. Deputy General Manager Yan Gang proposed future electric cars as a business model - the user only buy empty, do not buy batteries; the car is dead, they open into the gas station, changing batteries installed on OK ... ...

Yan Gang introduced JAC Shier Wu will be the end of the formation of 100,000 units the ability of new energy vehicles, but "out of the car is not enough light to do, must be the market must be expanded, there must be suited to their business model to run. "Yan Gang believes that this business model, need a government, battery manufacturers, car manufacturers to work together in three areas.

"There are several problems, as long as the problem resolved, the new energy vehicles will inevitably shape the market." Yan Gang dished out three questions,M8244 and lists measures.

The first problem is the cost of car. "Electric car, your battery." How to allow users to afford to buy? Yan Gang presents a novel point of view: let the future users do not buy batteries, buy only the amount of battery charge.

"It is equivalent to the status of owners are now: only buy a vehicle, to the gas station to pay only the fuel oil money every time. But the future is not refueling, but replacement of the battery charge-off of electricity." Yan Gang that , if this model can be transformed into successful out of the market, new energy vehicles will be able to exist.

Secondly, the usage charges. How do new energy vehicles cheaper than fuel cars? Yan Gang calculation, A1079 according to the current price of gasoline and electricity, is a 4:1 ratio, that is, the next one kilometer fuel takes about 4 dollars, then only one power of money.

Third, easy to use, the Yan Gang proposal can be extended with the current gas stations, refueling areas can also change to the battery.

Fourth, we must simultaneously solve the pollution problem in the battery. Must also be set up battery recycling processing system.

"As a result, the future, we can develop this kind of business model: The Government guidance, the establishment of 'stations'; companies do a good job of new energy vehicles, A1078 making fast and convenient replacement of the battery device, such as safety buttons, batteries, automatic pop-up; the same time, batteries battery leasing business enterprises. "

Yan Gang believes that this pattern, if achieved, is expected to make Hefei become the first new energy vehicles the most efficient city. A1148

Accelerated development of new energy vehicles, "Lithium-Ion battery Wars" hair-trigger release time :2010-2-10 10:43:59 Source: Beijing Youth Daily, the world's major automakers Toyota Motor, a subsidiary of Toyota Tsusho, with the Australian mining company Orocobre Ltd. Cooperation in the Argentina develop lithium ore and potash mine, added to the lithium industry, competition in South America. This cooperation, Toyota Tsusho will invest 4.5 billion U.S. dollars, of which the Government of Japan will provide a low-interest loans to the joint venture company, accounting for the joint venture total investment of 60%. According to Motorlink car reported that by 2014, the global automobile market size lithium batteries will rise to 248 billion U.S. dollars, an increase of 215 times in 2008. Predicted that 70% of the lithium-ion batteries used in mobile phones and notebook computers, along with the popularity M7318 of hybrids and electric vehicles, the world's new energy auto market is expected to expand rapidly, countries are beginning to participate in this new energy future, bearing their Auto develop "lithium war" at home.
● auto companies have to participate in upstream lithium

In fact, the global automotive enterprises to participate in the development have been and are taking lithium. Japan's Toyota, Nissan and Matsushita Electric Industrial and other related businesses already signed an agreement to jointly develop a new generation of unified specification cars lithium battery, and plans to mass production within 2 years. The Toyota Tsusho to participate in the development of the scale of the upper reaches of lithium mining is unprecedented, and will provide the industry to provide high purity, quality, first-class lithium metal, is the first in the automotive industry can be said to set a precedent.

Is not only Japan, Germany, from 2009 onwards launched a 360 million euros of the vehicle battery development program, almost all German cars and carry-owned energy giant to join. The German government said the implementation of the plan marks the era of Germany will enter the electric car. At the same time, Daimler Motor Company and RWE energy company said it would co-operate in the country to build 500 electric car charging stations. German auto industry alliance is expected in 2012 will be completed before the German series of electric vehicles, PowerBook G3 and opened a prelude to commercial production.

The industrialization of electric vehicles seems to be the next global mainstream. In this context, Volkswagen, Toyota and other major international Automotive Group have to take the initiative lithium battery field, with upstream and downstream enterprises to work more closely related to the joint venture and cooperation. Volkswagen Group announced a partnership with Japan's Sanyo rechargeable battery developer conclusion of a cooperation agreement, the two companies will jointly develop lithium-ion technology based on new high performance battery systems. Volkswagen expects to begin in 2010, lithium-ion battery technology for cars.

South Korea's largest auto parts production manufacturer Hyundai Mobis Company (HyundaiMobisCo.) last November 2 that it would be passed before 2013, with LG Chemical (LGChemLtd.) formed a joint venture to build a 40 billion won in lithium battery factory the annual output of 20 million. Currently Hyundai Mobis Hyundai Motor Company has entered the following into the Chinese market. Johnson Controls-Saft and Ford signed a Ford Transit (Transit) to connect the battery electric cars, lithium-ion battery supply contract. Ford Transit Connect battery electric car is a pure electric car, is expected to begin production from the end of 2010. It is reported that Johnson Controls-Saft recently has become the Azure battery supplier. In addition to Azure and Ford, the Johnson Controls-Saft is currently being addressed to Mercedes - Benz S-class [synthesis Photo Forum] hybrid, BMW 7 Series [synthesis Photo Forum] hybrid supply PowerBook G4 lithium-ion battery.

● "Lithium Wars" China is the main battlefield

Just recently, the U.S. released the "Joint Statement", said the two sides will launch in the U.S. electric car initiative, the two countries in the next few years, several 1 million electric cars in use. Last year, in March, China issued the "automobile industry restructuring and revitalization of planning" in the development of new energy vehicles have also developed a broad target - the next three years, China will form a 500,000 hybrid electric plug-in hybrid and ordinary type Energy Qijuchanneng. To this end, domestic Shanshangufen, CITIC Guoan, CITIC Baoan, Jiangsu Guotai, Tianjin power of God, universal, Ankai, Fukuda automobiles has begun a new round of research and development.

Statistics show that South Korea, China, Japan and Li-ion battery production in the three countries in the world market share of up to 96%, the competition is very fierce among the three countries. Experts believe that, despite the production of lithium batteries in China ranks third in the world, but in products, and technical level with Japan, the United States there is a certain gap, automotive lithium batteries are not yet the industrialization of the essay. At present, China's lithium battery development is still no real sense of the development plan, involving research and development, technology and materials, basically every business or independently, did not form together, coupled with our car battery power is still not achieved mass production, there is no large-scale application in electric vehicles, PowerBook G4 15inch power battery facing the development of short-term difficulties.

To this end, some have put forward three proposals, one, starting from the product itself. To study materials, improve material cost, electrical design, electric vehicles supporting facilities must be strengthened and improved. Second, to develop and improve lithium battery-related vehicle production, manufacturing standards, there are specialized agencies of the car battery to carry out testing. Third, short-term advantages of the country by supporting the existing businesses, enhance their competitiveness. Long-term, the state should take the lead, so that the core businesses, colleges and universities to form alliances to do some long-term strategic planning and technical line research.

Some professionals believe that lithium is becoming the most important for following the oil resources of power, while the use of new energy lithium battery-powered vehicles will become the future direction of development of the automotive industry. In 2009, China has more than 13.5 million Qijuchanneng, China has become the center of the global automotive industry, and therefore the future of China's automobile market will also become the world's new energy vehicle development, has a main A1012 battlefield, lithium power war is inevitable

Mobile phone battery performance to be to upgrade high-capacity long standby product will become the mainstream of

"Sent the message too much, too old for mobile phone batteries." Finished just before the Spring Festival holiday,Armada E500 many users sent a such a complaint. With the constant improvement of mobile phone applications, users and other mobile phone standby time performance, set higher requirements.
The continued low prices of mobile phones, sell mobile phones have been shrinking profits. In contrast, batteries, cell phone accessories profits rising. In order to obtain profits, a lot of mobile phones only at the factory is equipped with a battery, which is the emergence of brand-name cell phone batteries provide a certain amount of space.

Hodge-proliferation of mobile phone batteries, to a certain extent, reduce the user's use of effects. Beijing Industry and Commerce Bureau had just released a batch of unqualified list of mobile phone battery, a total of 33 mobile phone batteries on the market Heibang and out of Beijing. laptop battery It is understood that delisting of products including Paper up, excellence, SICT brands such as 33 kinds of mobile phone batteries, the main problem is that signs, discharge performance and cycle life and other indicators of failure. Some phones have not indicated charging limit voltage, warning note, so that consumers can not understand the actual situation. Discharge the battery performance is one of the main indicators of the quality of good or bad, if not compliance will affect the normal use of cell phone batteries. There are a number of mobile phone battery life cycle is too low, which is consumers often complain that the battery can only use a few months on the bad reasons.

At the same time, as handsets become more powerful, users of battery capacity requirements higher and higher. In recent years, the industry began A1175 widespread use of bigger, longer life lithium-ion batteries. Previously, the former Ministry of Information Industry promulgated YD1268-2003 "mobile phones and lithium batteries and charger safety requirements and test methods", in which the temperature of thermal shock test standards have been changed to 130 ℃, become the mobile phone industry, general industry test standards ; in September 2005 by the State Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Technical Committee alkaline battery under the auspices of the national standard revision meeting, the proposed new national standard, "revised edition", in which the temperature of thermal shock test standards into a 130 ℃ However, A1185 for various reasons, is expected in September 2005 promulgated a new national standard still has not issued. At present, both the battery manufacturer or the mobile phone manufacturers in general would be 130 ℃ as a lithium-ion battery temperature of the thermal shock test standards, and in the battery design, production, quality control, procurement and other areas commonly used by this standard. Today, the new cell phone batteries also need to put the national testing standards.

Analysts pointed out that, with the business smartphone show exponential growth, from the GPS electronic navigation to the MP3 music player, and then to WIFI wireless Internet access and so on, endless variety of phone functions, mobile phone standby time becomes the basis for applications to protect these features . A normal capacity M9324 of mobile phone battery apparently can not meet their daily use, this time high-capacity, long standby mobile phone batteries mobile phone batteries on the market will become the mainstream.

Battery use Mistakes 1.1 Battery charge capacity and the engine does not match the
According to the engine type and conditions of use and reasonable selection of battery charge capacity, is to improve the battery's economy, laptop battery extending its life is one important way. Starting the engine starter, the battery output current is large, under normal circumstances for the 150A-200A, at low temperature (-10 ℃) start when the output current up to 250A-300A. If the battery charge capacity and the engine does not match the battery charge capacity is too small, then start the resistance is large, the small charge-discharge capacity of the battery in dramatic circumstances, is bound to speed up the active material per unit time and the reaction of sulfuric acid, so that battery temperature rise high, while the curved plate due to overload, resulting in a large number of active substances fall off, the early damage plate, so that battery life shortened. If the battery charge capacity is too large, although the above-mentioned problem does not occur, but can not make full use of its active substances, so that economic decline in battery. So battery charge capacity, must be matched to the engines. 02K7039 Battery charge capacity is usually the choice should be based starter power, voltage and electric equipment load determined.
1.2 Battery parallel mixed
Some drivers at the start when the engine due to lack of electricity keeping the original battery on the parallel on a fully charged battery shared use. In fact, after fully charged batteries in parallel will be much less than the charge current to save battery power charging, highly active substances causing plate shedding, affecting their life. Battery in parallel at the same time and can not provide a great starting current to the starter, but is not conducive to starting the engine. The correct approach should be to save enough battery power removed, replaced with fully charged battery, and then start the engine.
1.3 Battery Tandem Mixed
Use in the battery, sometimes the emergence of new and old batteries used in tandem phenomenon, does not know that, this approach will shorten the battery life. Because the new battery of chemical reactive substances are more high voltage, resistance of the smaller (12V new battery internal resistance is only 0.015-0.018Ω); ThinkPad X60 and the old battery terminal voltage is low, a larger resistance (12V old batteries resistance in the 0.085Ω above). If the old and new batteries mixed in series, then the charge state, at both ends of the old battery charge voltage will be higher than at both ends of the new battery charge voltage, resulting in a new battery charger has not yet sufficient and the old battery charger already too high; in the discharge state , since the new battery's charge capacity than the old battery charge capacity, resulting in excessive discharge the old battery, or even cause the old battery inverse pole. Therefore, the battery must not be old and new mix.
In addition, different battery charge capacity can not be mixed in series because the two kinds of charge capacity of different batteries used in tandem, often small capacity of the battery will charge excessive charge or discharge, shortening their useful life.
1.4 diesel vehicle batteries continue to use single-cell damage
Diesel engine compression due to relatively large, the required starting torque is also large, so under normal diesel engines are used 24V voltage is starting to improve FRU 92P1167 the ratio of starter power, but the generators and the entire vehicle electrical equipment still use 12V voltage, so diesel vehicles circuit is equipped with a voltage conversion switch, starter switch when the two 12V batteries in series will work to 24V voltage power supply, in the non-start state, the change-over switch in turn restore the two batteries in parallel so as to meet the needs of 12V voltage . However, when a battery in which a single cell is damaged, some drivers continue to use after their formal short circuit, such as two battery terminal voltage range, will result in a larger discharge current and charging current, resulting in damage to batteries and generators Therefore, single-cell battery diesel vehicles damaged should be ThinkPad Z60t immediately replaced or repaired, but not single-cell battery short-circuit after continued use.
1.5 ignore the clear vent
Battery charging and discharging process will produce hydrogen and oxygen, especially in the over charging, the water is electrolysis and produce large amounts of hydrogen and oxygen. Add liquid battery lid vent hole is used to distribute these gases. Usually ignore the vent of the dredge, causing vent obstruction, battery in the chemical reaction produces heat and gases can not be distributed, the internal battery temperature and pressure will continue to rise, eventually leading to battery explosion. Therefore, attention should be paid in the routine maintenance dredging vent to prevent dirt clogging vent.ThinkPad Z61t

Battery

Battery [3] is a kind of cell, its role is to be able to store a limited power, FRU 92P1137 in appropriate places for use. How does it work is to chemical energy into electrical energy.
It is filled with spongy lead of lead as cathode, filled with lead dioxide as positive electrode of lead and 1.28% of the sulfuric acid used as electrolyte. While charging, electrical energy into chemical energy, discharge chemical energy into electrical energy again. Battery discharge, the metal lead is the cathode oxidation reaction, was oxidized to lead sulfate; dioxide lead is cathode, reduction reaction occurs, is reduced to lead sulfate. When using DC battery charging, the bipolar lead and lead dioxide were generated. After the removal of power, it recovered to pre-discharge state, the composition of chemical batteries. Lead-acid battery is able to repeatedly charge and discharge the battery, called the secondary battery. Its voltage is 2V, usually three lead-acid batteries in series up to use, voltage is 6V. Vehicle using a six lead-acid batteries in series into a 12V battery packs. Lead-acid batteries in use for some time to add distilled water to maintain electrolyte containing 22 ~ 28% of diluted sulfuric acid. 02K6651
Discharge, the electrode reaction: PbO2 + 4H + + SO42-+ 2e-= PbSO4 + 2H2O
Negative reaction: Pb + SO42-- 2e-= PbSO4
The overall reaction: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (the right response is discharge, to the left reaction is charging)

January 21 morning, the Golden Dragon Group's Board of Directors decided to convene: Following in Suzhou lithium electric car project put into operation, in Xinxiang Yuanyang frozen to build a production base of electric cars lithium battery production line, a total investment of 150 million yuan, annual output will reach 2 million vehicles. This project will become the largest lithium battery electric vehicle project.
In accordance with the dragon of the plan, to expand the 2011 lithium battery electric vehicle production scale, but most recently, lithium battery electric vehicle market conditions are particularly good, especially in the Yangtze River Delta region, "where consumers are more receptive to new things, We produce the electric car was not enough to sell, so ahead of expansion of output. " Golden Dragon Group's subsidiary in Suzhou, Lung Yeuk engineer YIN Yong Ting said.
January 21 afternoon, the Golden Dragon Group is responsible for research and development of lithium YIN Yong-huang, with the chief engineer ThinkPad A21M Wang Shikui and drove more than 40 kilometers away from Xinxiang Jinlong Yang freezer production base in the former group, study site selection. "This infrastructure has been improved, there are workshops, as long as the installation of equipment, is expected to fall this year, the production line will be completed, we can reach an annual output of 2 million of the scale." Wangshi Kui said. "Our goal is to project fully completed by 2015 and complete the Group's strategic layout of the country, reaching an annual output of 5 million in vehicle production and operation of the size, and become the nation's largest manufacturer of electric bicycles." Li Changjie said.
Both auto makers to supply battery power
Golden Dragon Group, in addition to the hippocampus, Lifan outside the automotive battery power, and Zhengzhou Nissan, Yutong has also established a link
January 25, Golden Dragon Group's deputy general manager ThinkPad R60 of Hebei Xue-feng and his party arrived in Chongqing Lifan, Lifan met with high-level. The two sides to the Golden Dragon Group, Lifan Group, reached a preliminary intention to provide motive power batteries, although the contents are confidential, but he revealed: "has been set, and soon the signing of an agreement is concluded."
In late January, Golden Dragon has signed a cooperation agreement with the hippocampus. "In the future, the hippocampus power batteries of electric vehicles by us, this number is quite impressive." Wang Shikui this cooperation has been very satisfied, "At present, companies, and the combination of the hippocampus, but also tend to run cars for official use by test run the way problems are identified, to identify shortcomings, and then solve the problem, eventually toward industrialization. "
"For us, can provide the impetus for the hippocampus and Lifan batteries, will give us the development of a vast space." Wangshi Kui said.
Golden Dragon Group Dynamic Power Co., Ltd., Henan Li Ji Cheng, executive vice president of introduction, in addition to, and the hippocampus, Chongqing Lifan's co-operation, they and the Zhengzhou Nissan, Yutong and other enterprises have also established cooperative relations.
We also have to produce electric vehicles that a
Production of electric cars, only the initial stage of the road shock Jinlong, Li Changjie has a more ambitious goal - produce electric commercial vehicles, the current prototype has been produced by the
September 1, 2009, Golden Dragon Group and Taiwan's Aerospace Industrial Development Corporation will jointly, joint ventures,ThinkPad T60 annual production capacity of 300,000 battery-powered cars and power projects, joint working and the power battery electric vehicle research and development and production.

Although Li Changjie, said an official for the electric vehicle market, but also take a few years time, but in fact, Golden Dragon Group has Taicang in Jiangsu Province to produce lithium-electric vehicles like electric cars, not only the tractor, go karting, sightseeing car , patrol cars, as well as for home residents with cars, these electric vehicles are used by Golden Dragon Group's own production of lithium batteries.
In the reporter's impression that, while many airports, railway stations are used in electric tractor. "Those tractors are used in ordinary lead-acid batteries, speed is only 20 kilometers per hour, but the battery is not durable, but also pollute the environment. We produce a variety of tractor As a result of its own lithium battery, can be up to 80 kilometers per hour above, very suitable for military, airports, train stations, the use of. People's Liberation Army General Armament Department has been kind of cars I've seen, and very interested, willing and us, them that the market is a big one. "YIN Yong Ting said.
According to reports, the current produced by the household sample,40Y6797 there are two electric vehicles: Jeep style, commercial vehicle style. "We will participate in the car this fall, Shanghai Expo, so that everyone finds fault with the matter. Now, being a production license to the state." YIN Yong-huang said, "quick, then come next year, the Pixia."

Golden Dragon Group is the world's largest precise copper tube manufacturer, the product at the domestic level for more than 60% market share, accounting for one sixth of global market share. As a brass industry, boss, Jinlong Why enter the lithium industry? "Although we have brass in 2009 reached more than 100 billion yuan of output value, but the processing industry profits is relatively low. New energy is different, and 2009 profits of only lithium batteries on 7,000 million, comparable to our the number of brass-made ah! "When it comes to enter the lithium batteries, Li Changjie excited. "In the future, new energy will be our other pillar industries. 3 ~ 5 years, lithium battery electric vehicles, power batteries and electric vehicle output will reach 500 billion size of the output value will be far more than copper." "Lithium battery separator material in the past to rely on imports, and now Golden Dragon Group's independent research and development of alternative product output has accounted for a certain percentage of the domestic market share and become the company's new profit-making points." Cheng Ji, introduced in April 2008, Xinxiang special grant of 200 acres of city land, the Group's chemical and physical state in Xinxiang Industrial Park, Xinxiang built in Section Technology Co., Ltd., is committed to lithium battery, power battery, 3V lithium battery, new energy and related materials research and industrial of. 40Y6799 "We are now the largest manufacturer of lithium-powered."
As Li Changjie said, support the Golden Dragon Copper Tube Group, from the air conditioning industry, energy industry to a new large-span extension is that the Golden Dragon Group, lithium battery separator has acquired intellectual property rights, exclusive access to the technology for China's intellectual property business. Li Changjie so proud is now Golden Dragon Group's manufacturing power batteries needed to account for the domestic half of the membrane material in the lithium battery industry has a greater influence and technological development advantages.
Henan province is to build electric car
Golden Dragon Group's strength in the hair behind the electric car is the policy bias in Henan Province. Under the guidance of the policy, many manufacturers have been launched electric car project

3G mobile phone battery market's crowded Times

With 3G networks in the accelerated process of global commercial, 02K6928 3G users also appeared to grow substantially. Technically advanced, 3G business has a unique appeal, prompting users to more and more frequently use a variety of multimedia services. Short period of 10 years, only to have a cell phone call from the set of functions to develop into a variety of functions in one portable device. In the meantime, the development of mobile phone batteries followed the evolution of technology development.

3G era, a number of mobile phone battery manufacturers (Scud, BYD, Loi Moritaka, etc.) are introduced several new mobile phone battery, greatly's crowded trend, the author sums up what the current development of mobile phone battery showed three major features: high-capacity, long standby, environmental protection and safety. 02K7054

High-capacity, long standby: with business smartphone show exponential growth, from the GPS electronic navigation and then to the MP3 music player, WIFI wireless Internet access and so on, endless variety of phone functions, mobile phone standby time applications in the protection of these features basis. A normal capacity of mobile phone battery apparently can not meet their daily use, this time high-capacity, long standby mobile phone batteries mobile phone batteries on the market will become the mainstream.

Security: The term is now more than ever a period of time have been of concern to everyone. In the experienced shoddy mobile phone battery explosion, the consumer is more rational, integrated balance of the consumer,ThinkPad A20 the price is a measure of a product is no longer the only indicator, the same major mobile phone battery manufacturers found a market sensitive to atmosphere, and launched safety explosion-proof business mobile phone batteries, and also covered by commercial insurance companies, merchants well-intentioned, but also to the user more of a security.

Green: economic and social unity, is a mature company should do. More and more enterprises in improving production efficiency while also interested in social welfare. Mobile phone battery industry is also true that many large companies are committed to R & D and production of more green cell phone batteries, reduce environmental pollution, to avoid the disposal of mobile phone ThinkPad A20M batteries free of ecological damage. This point, fortunately saw the development and progress of society as a whole.

Mobile phone battery market's crowded, will provide more varied choice. However, given the many cottage manufacturers to follow suit and profit-making, suggest that you purchase a time when mobile phone batteries to buy from the formal channels, such an optional mobile phone battery has become more safe, secure.

Batteries and Environmental Protection Potential contamination of used batteries has caused widespread concern in the community.laptop battery China is the world's number one dry battery producing and consuming nations, our data show that China currently has more than 1,400 battery manufacturers in 1980, the production of dry batteries volume has surpassed the United States and the largest in the world first. In 1998 the production of dry batteries in China amounted to 14 billion, while the same year the world's total production of dry batteries is about 30 billion.
Such a large quantity of batteries, making a big problem exposed, that is, how to make so many batteries do not destroy the environment pollution of our survival. According to our survey, used batteries containing heavy metals as well as the waste acid, waste alkali and other electrolyte solution. If you arbitrarily discarded batteries will destroy the corruption of the water, erosion of our survival crops and land, our environment is facing a huge threat. If the one on the 1st cell in the ground and rotting, it's toxic substances make one square meter of land to lose value; throw a coin battery into the water, which contains toxic substances which killed more than 60 million liters of water body pollution , equivalent to a person's life, water; used batteries containing heavy metals cadmium, lead, mercury, nickel, zinc, manganese, etc., in which cadmium, lead, mercury is a great harm to human body substances. The nickel, zinc and other metal although to a certain range of concentration is a useful material, 08K8198 but in the environment over the limit, but will also harm the human body. Waste batteries leaking heavy metals can cause rivers, lakes, sea and other bodies of water pollution, endangering the survival of aquatic and water use, an indirect threat to human health. Waste acid, waste alkali and so on could contaminate the electrolyte solution, so that land acidification and salinization, which decker around us like a time bomb. Therefore, the collection and disposal of used batteries is very important, if disposed of improperly, may be on the ecological environment and human health, cause serious harm. Randomly discard used batteries is not only pollute the environment, is also a waste of resources. Some people forget an account to the country's annual production of 10 billion batteries, annual consumption of 156,000 tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc chloride, 79,000 tons ammonium chloride, 4.3 million tons of carbon rod. While advanced technology has given us the right direction, but the phenomenon of pollution in China's battery is still not optimistic. Most of China's 08K8197 current domestic waste has been mixed with used batteries together into the ground, over time, after the battery into decay, heavy metal leaching, both could contaminate groundwater bodies, they could contaminate soil and finally through a variety of ways to enter human food chain. Biological uptake of heavy metals from the environment through the food chain biomagnification, grade by grade in the higher organisms tens of thousands of times more enriched in, and then enter the human body through the food chain, and in some organs savings cause chronic poisoning, Japan Minamata disease is a typical case of mercury poisoning.
Batteries are generally divided into disposable batteries and rechargeable batteries. The main disposable batteries, including zinc-manganese batteries (zinc and manganese dioxide), zinc mercury batteries (zinc and mercury oxide) and lithium batteries and other several categories. The main rechargeable batteries include cadmium - nickel, iron - nickel, zinc - silver, zinc - air and lithium - iron sulfide and lead-acid batteries and so on. Our daily life is the most frequently used zinc-manganese batteries and zinc-mercury batteries, leaving the battery pollution is mainly caused by mercury (Hg) and cadmium (Cd).
Mercury toxicity
Mercury, which are commonly called "mercury" is a liquid at room temperature the material, can prevent the battery in the cathode zinc oxide, this approach to improve the storage life of the battery. Thus, as early as in the previous zinc used in batteries to do extremely overcast almost all do a certain amount of mercury preservative. However, the chemical combination of mercury and mercury have the neurotoxicity of endocrine system, immune system, also have an adverse effect, it will trigger people's slurred speech, unsteady gait, limb paralysis, leading to generalized convulsions, mental disorders and died.
For a long time, China in the production of dry batteries, it is necessary to join a toxic substance - mercury or mercury compounds. China's mercury in alkaline batteries up to 1% ~ 5%, 0.025% neutral dry-cell batteries, dry batteries every year for the production of dozens of tons of mercury amounted to much. As technology advances, the 92P1075 battery began to implement a low mercury and mercury-free, mercury substitutes Forafac fluorinated polymer surfactants in preventing the corrosion of zinc has achieved good results.
Discarded mercury batteries in nature will slowly overflow from the battery into the soil or water, and then under the action of microorganisms, inorganic mercury can be transformed into methylmercury, gathered in the fish's body, the human consumption of such fish , the methylmercury enters the human brain cells, people's nervous systems were severely damaged, in serious cases would be crazy to death. Well-known Minamata disease in Japan is caused by methylmercury.
Cadmium Toxicity
Cadmium is not a trace element necessary for the human body, the body of newborn babies, and there is no cadmium, but increased with age, and gradually accumulated. Cadmium with renal toxicity, which caused kidney damage is irreversible. At the same time after renal injury may also be secondary osteoporosis, osteomalacia and fractures. In 1993, the International Union Against Cancer will be set at IA level carcinogen cadmium. For these reasons, many developed countries have recommended a ban on the use of nickel-cadmium batteries and nickel-metal hydride battery has been replaced by nickel-cadmium batteries, avoiding the use of cadmium. In China, the vast majority of battery manufacturers are still using cadmium as raw material for production of the battery, making the battery further increase the dangers. Affected by long-term consumption of cadmium contaminated water and food,ThinkPad R40 can lead to bone pain and disease, cadmium into the body, causing osteomalacia skeletal deformities, and in severe form of natural fractures, and even die.
Manganese toxicity
Excessive levels of manganese accumulation in the body can cause neurological dysfunction, an early manifestation of an integrated sexual dysfunction, the emergence of heavier speech monotonous, dull expression, emotional indifference, accompanied by psychological symptoms.
Lead toxicity
Lead a major role in the nervous system, hematopoietic system, digestive system, and liver, kidney and other organs, can inhibit the synthesis of hemoglobin metabolism, but also directly on the mature red blood cells, for infants, young children much, it will lead to children's physical development retardation, chronic lead in the prime of childhood mental retardation.
Nickel toxicity
Nickel powder dissolved in the blood, to participate in the body circulation, with strong toxicity, can damage the central nervous system, ThinkPad R32 causing abnormal blood vessels, severe cases lead to cancer.
Zinc toxicity
Zinc is an essential element of the human body, less toxic, oral zinc sulfate 1000mg only people with acute poisoning, but the inhalation of zinc oxide dust can cause poisoning. Its symptoms are generalized fatigue, muscle pain, difficulty breathing, vomiting, diarrhea, severe heart weakness, prostration, convulsions died. Zinc sulfate, zinc chloride penetrated the skin mucous membrane, it can produce dermatitis and ulcers. Of zinc to fish and aquatic toxicity of the toxic than the people, so the water quality requirements for fishing in the water content of zinc per liter should not exceed 0.1mg.

Domestic compatible laptop battery

2 years to accompany my original notebook battery, and finally generating a 5-minute time to 92P1102 submit his resignation to me the report. For the computer peripherals do not understand me, and had captured over the weekend knowledgeable brother to the digital store and bought the batteries. To go before I made up my mind to give me books with a pink sony original batteries, but a Look at the price of original let me speechless, thinking that these small Japanese really would make money, the parts also so expensive, simply say this: sinister ! !
Look at my teeth look like my brother, laughing at the same time worshiper of foreign things I purchased my 180-degree direction of the major adjustments - made compatible with laptop batteries.
Brother introduced Feihong eagle is a brand of notebook batteries, the box to do it very carefully. Casing clean, flat no indentation, open the battery box was soft sponge wrapped in neat, JANSEN, battery pack is also outside of professional static bag, battery shell smooth Seamless, feeling fine ... ... Oh, is quite formal 呀they looked very agreeable I like. Girls are like the appearance of animals, to see such shiny appearance, the hearts of the Chinese-made brand battery is compatible with the ill feelings immediately dispelled by half. laptop battery
2nd Round - cost-effective to fight
Cool, cool! ! Kind of animal in nature to see my brother, hastened to stop me to continue to drool.
Price! Yes, the price is how like? Store's answer surprised me! Would not you? Only one third of the original?
Service-na? Actually there is one and a half!
Have a product certification and the international inspection reports Mody? I took out store CE certification, the United States UL safety certification and 3C certification.
Procedures are still a full-ah, but the psychological or the right price with the original, when there are too many gaps in the offing. Friend was already blue-moon to help me buy a piece of notebook batteries. When I was about to stop the shot with a "is a mule is a horse, pull out yo." Put my words stuck in his mouth.
3rd Round - practical application, my battery will not explode?
I can not wait to bring home a new battery according to the notebook, but fortunately, Fei-Ying laptop battery in terms of workmanship,92P1077 or both, and in terms of the degree of matching the original battery did not make any difference.
"I can go home it?" "No, resolutely not work! Case if the explosion of how to do? You have to stay with my charge and discharge time I can let you go!!" Laoge reaching helpless surrender.
End of electrical impulse, I picked up a stopwatch exaggerated start to discharge time. Feng watching the latest movies, shows battery capacity is 29%.
"Yes, right?, What say? This time relieved it, worshiper of foreign things little girl!" Laoge proud smile at me.
"But have not previously heard of this brand that way?" 92P1073
4th Round - in-depth exploration in preparation for defections Laoge
I have been a great importance to the brand, so a search online a bit so that my brother proud of this brand. Feihong Eagle brand original laptop batteries behind an area of about 2,500 square meters, existing staff of more than 200 people, and have a professional, high quality, efficient R & D team, R & D department staff about the management of one-third of the total number of standardized production base. Prior to overseas markets such as Europe and the United States is committed to developing and highly praised.
Hey ~ ~, finished finished, defections Laoge the complete failure of the plan! ! 08K8199

Principles of the battery

In the chemical cell, chemical energy directly into electricity through the battery is carried 92P1101 out within the spontaneous oxidation, reduction and other chemical reactions the result of the reaction were carried out in two electrodes. Negative active material from the more negative potential and a stable reducing agent in the electrolyte composition, such as zinc, cadmium, lead active metals and hydrogen or hydrocarbons. Positive active material from a more positive potential in the electrolyte composition of a stable oxidizing agent, such as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or air, halogens and their salts, oxygen-containing acid and its salts, etc. . Electrolyte is a good ionic conductivity of the material, such as acids, alkali, salt solution, organic or inorganic non-aqueous solutions, molten salts or solid electrolytes. When the external circuit disconnected, although there potential difference between the two poles (open circuit voltage), but there is no current, stored in the batteries do not convert 92P1089 chemical energy into electrical energy. When the external circuit is closed, the two electrodes under the effect of potential difference that there is current flowing through the external circuit. The same time, the battery inside the electrolyte does not exist due to free electrons, charge transfer must be accompanied by two poles active material and electrolyte interface, the oxidation or reduction reactions, as well as reactants and reaction products of mass transfer. Charge transfer in the electrolyte but also by the migration of ions to complete.92P1087 Thus, within the normal battery charge transfer and mass transfer process is to ensure that the necessary conditions for the normal output of electricity. When charging, the battery inside the transmission power and the direction of mass transfer and discharge exactly the opposite; electrode reaction must be reversible, in order to ensure the opposite direction of mass transfer and mass of the normal electrical processes. Therefore, the electrode reaction reversible constitutes a necessary condition for batteries. Reaction for the Gibbs free energy (coke); F is Faraday's constant = 96500 base = 26.8 ampere-hour; n the equivalent number for the cell reaction. This is the reaction of the battery and battery electromotive force between the basic thermodynamic relations, but also calculation of cell energy conversion efficiency of the basic thermodynamic equation. In fact, when the current flows through the electrodes, the electrode potential must 08K8194 deviate from the thermodynamic equilibrium of the electrode potential, a phenomenon known as polarization. Current density (unit electrode area adopted by the current), the greater the polarization more serious. Polarization phenomenon is caused by the battery energy loss of the important reasons. Polarization for three reasons: ① from the cells caused by the various parts of the polarization resistance is called Ohm polarization; ② from the electrode - electrolyte interface layer caused by charge transfer blocked the process of polarization is called activation polarization; ③ from the electrode - electrolyte interface layer caused by slow mass transfer of polarization is called concentration polarization. Reduce the polarization method is to increase the electrode reaction area,08K8196 reducing the current density, increasing reaction temperature and to improve the catalytic activity of the electrode surface.

Battery Description

Main performance parameters of the battery electromotive force, capacity, specific energy and resistance.ThinkPad R51 Electromotive force is equal to units of positive charge from negative to move through the cathode inside the battery when the battery of non-electrostatic (chemical force) done by power. Electromotive force depends on the chemical properties of electrode materials, and battery size. The total output of the battery can charge capacity of the battery capacity in ampere-hours is usually treated as a unit. In the battery reaction, 1 kg-reactive substances produced by the battery power is called the theory of specific energy. Cells were actually higher than the energy smaller than the theoretical specific energy. Because the batteries are not all reactants reaction according to the battery while the battery internal resistance caused by electromotive force must fall, so often the battery than the energy, high-called high-energy batteries. The larger the size of the battery, the smaller the resistance.
Battery energy storage is limited, the battery can charge the total amount of output is called its capacity, usually treated as a unit in ampere-hours, it is also one of the battery performance parameters. The capacity of the battery related to the number and electrode material, namely the size of the electrode. laptop battery
Practical chemical batteries can be divided into two basic types: primary cells and batteries [1]. Made after the original battery can generate current, but the discharge is completed Jibei abandoned. Battery also known as secondary batteries before use should conduct charge, charge to use after discharge, discharge can also be charged after the re-use. Battery charging, the energy converted into chemical energy; discharge, chemical energy into electricity.
[Edit this paragraph] Battery History
In ancient times, humans may have been continuously in research and testing "electric" this things. One is considered the clay history of several thousand bottles in 1932 in Iraq near Baghdad, have been discovered. It has a copper cylinder inserted inside the iron - used to store static electricity may be used, but the bottle's secret may never be revealed.
Whether the ancestors of manufacturing the clay bottles know about static electricity thing, but is certain that the ancient Greeks should know. They know that if the friction and an amber can attract light objects. Aristotle (Aristotle) also know that there such thing as a magnet, it is a powerful magnetic force to attract iron and metal ores.
1780, Italian anatomist Luigi Galvani do frog dissections, the hands were holding various kinds of metal equipment, inadvertently touched the frog's thigh at the same time, the frog legs twitch muscles at once a moment, as if stimulated by the current , but only with a metal instrument to touch the frog, but there is no such counter-on. Galvani believed that this phenomenon occurs because the animal body a kind of internally generated electricity, which he called "bio-power." Galvani in 1791 the results of this experiment written papers published in the academic community. FRU 08K8193
Galvani's discovery aroused great interest to physicists, they are competing thoughts Galvani repeated the experiment, an attempt to find a way to generate current, the Italian physicist volts after the experiment several times that: Galvani's " bioelectricity "is not correct, the frog muscle has been able to produce current, probably some kind of liquid in muscle at work. In order to demonstrate their point of view, voltage to two different kinds of metal immersed in a variety of solution testing. The results showed that the two metal film, as long as there is a place with the solution of chemical reaction between the metal can generate electricity.
1799, volts into a zinc plate and a silver plate immersed in salt water was found to connect two metal wires have current through. So he put a number of zinc and silver film between the pads of cloth or paper soaked in salt water, flat-stacked. Touching both ends, it will feel a strong current stimulus. Volts using this method was successfully made the world's first battery ─ ─ "V of the stack." This "V Stack" is actually a series of batteries. It became an early electrical experiments, telegraph source of power.
Italian physicist repeated on many occasions volt Galvani experiment. As a physicist, his attention focused on those two points, metal, not in the frog's nerves. For the Galvani discovered the phenomenon of frog legs twitch, he thought it may be related to electrical related,92P1060 but he thinks the frog muscles and nerves in the electricity does not exist, he seems to presuppose the flow of electricity may be caused by two different metals contact with each other generated, whether the contact with metal or dead animal activity has nothing to do. Experiments show that as long as the interval with two kinds of metal film impregnated with saline or alkaline (or even as long as the wet and) cardboard, linen, leather or other sponge-like thing (he thinks it is necessary to make a successful experiment ), and metal wire connecting the two pieces of metal together, with or without frog muscle, there will be current through. This indicates that the organization of power is not generated from the frog, the frog legs served only to the equivalent of a very sensitive electroscope only.
1836, Britain's Daniel on the "V of the stack" was modified. He used sulfuric acid as the electrolyte, to solve the battery polarization problem, create the first non-polarized, to maintain a balanced current ─ copper zinc batteries, also known as "Daniell cell." Later, one after another depolarization better the "Bunsen battery" and "Grove cell" and so on come out. However, these cells are present voltage with the use of prolonged decline problems.
In 1860, France's Plante invented the battery electrode made of lead. The battery is unique in that when the battery so that the use of a voltage drop, you can give it pass in order to reverse current, so that the battery voltage is picked up. Because the battery can be charged, you can re-use, so call it "battery."
However, no matter what kind of batteries are required to fill the liquid between the two metal plates, so transportation is very convenient, 08K8214 especially the battery is used in liquid sulfuric acid, in the moving time is very dangerous.
Also in 1860, France's Leikelanshi (GeorgeLeclanche) has invented the world's widely used in batteries (carbon-zinc batteries) predecessor. Its anode is zinc and mercury alloy rod (zinc - a prototype Volt battery anode, a cathode material proved to be one of the best metal), while its cathode is a porous glass with crushed dioxide dress a mixture of manganese and carbon. In this mixture is inserted in a carbon rod as the current collector. Anode rod and anode cups were immersed in the ammonium chloride as the electrolyte solution. This system is called "wet-cell batteries." Leikelanshi manufacture batteries but it is simple but cheap, so until 1880, was only to improve the "dry" instead. Can be improved into a zinc anode (ie, the battery case), rather than a liquid electrolyte into a paste, basically this is what we are known as carbon-zinc batteries.
In 1887, the British invented the first dry Hellesen. Battery electrolyte is a paste, will not spill, easy to carry, so access to a wide range of applications.

Lithium iron phosphate batteries in China involved in the specific application of the technical aspects of a relatively small number of patent applications.

2, Enlightenment and Suggestions

Technology development process made clear laptop battery that no one major technology and extensive application of the generation process, is bound to accompany the large number of patents produced clan. With the intellectual property rights in commercial applications of new technologies highlight the importance of the major companies in major technical areas of intellectual property rights territories against each other, in order to grasp the fierce competition in the business opportunities. Lithium iron phosphate battery technology in the field, our late start, did not understand the basic core of patents, this paper, the status quo has the following recommendations:

1. To speed up the patent application lithium iron phosphate

Lithium iron phosphate battery technology research time is not long, in the conductivity, the energy density, power density, tap density, materials, stability has a great room for improvement. Therefore, Chinese enterprises should increase R & D investment to accelerate the domestic patent applications, possess certain technological advantages of the enterprises overall layout, and key technical point in the foreign patent applications. Even if the future is to master the core of the foreign patent infringement complaint when the big companies, which have numerous domestic enterprises can patent cross-license negotiations, litigation, etc. for their own anti-seize the initiative. Further, with the core of the patent may also be possible in the future formation of lithium iron phosphate batteries ThinkPad T41 take place in the patent pool.

2. Around the foreign company's core patent Layout

From Figure 2 we can see that foreign enterprises in China before 2008 did not patent the layout (except for Japan, 2). China is a battery-manufacturing country, with the lithium iron phosphate battery technology development, China's future is likely to be iron phosphate lithium battery manufacturing country. When the foreign master core technologies of several companies aware of their patents in China, the layout of the deficiencies will certainly increase the intensity of patent applications in China. According to the novelty of patent examination and the relevant priority provisions in the foreign patent application, after a certain period (up to 32 months), the foreign patent application in China can not be re-apply. Therefore, if foreign companies want to carry out its core patents in China, the layout, only the original core patented technology to improve a little, and then the application in China. Chinese enterprises ThinkPad T42 can be the first to step in, targeted to study abroad, the company's core patented technology, its slightly improved (as can be creative patent examination as a standard), the patent application made in China. Through this targeted distribution, domestic enterprises can reduce their lithium iron phosphate batteries in China's market potential threat.

3. Strengthening the structural design of the battery, the battery combination control studies

We can see from Figure 3, the domestic battery manufacturers, or patent applications filed in the Institute focused on lithium iron phosphate ThinkPad T43 battery lithium iron phosphate materials, preparation methods, structural design of the battery, battery control, slightly less than combined. Lithium iron phosphate batteries multi-domain applications may generate new technical problems, for example, when lithium iron phosphate batteries as the car battery power when the structural design of the battery, battery control, there will be some combination of special technical problems, or even Many are not limited to batteries (such as automotive power systems) the periphery of technological innovations. Domestic enterprises in iron phosphate lithium battery to increase R & D investment, we must also note that patent applications related to the layout, so that domestic enterprises in iron phosphate lithium battery materials, preparation methods,ThinkPad R50 application techniques, etc. to master a full range of intellectual property.

Lithium iron phosphate battery patent fight fierce Chinese enterprises should speed up the layout of

At present, the world's leading automotive enterprises in the field of new energy technologies has unleashed a fierce contest. FPCBP95 In this competition, for the lithium iron phosphate (LiFePO4) battery level of the patent battle heated up. For example, the Texas State University and its commercial mandate Hydro Quebec, Canada, accused the United States battery manufacturers Gao Bo infringement lawsuit energy companies has now stalled, and the U.S. General Motors in 2010 to market electric car Volt, is used by his company developed a high lithium iron phosphate batteries. If the high Bo lost, GM Volt will also be caught in infringement disputes. Lithium iron phosphate batteries are also a number of patent litigation to China's automobile industry development has brought a lot of uncertainty. For this reason, this paper lithium iron phosphate batteries to analyze patent applications in China for the trade on the information.
1, the patent analysis of the situation

By the State Intellectual Property Office SSIPEX granted full library of patent data search, the current open lithium iron phosphate batteries on the number of patent applications, a total of 203.

Among them, Figure 1 shows the trend analysis laptop battery of patent applications from 2003 onwards, China began on lithium iron phosphate batteries patent application, which is the world's first lithium iron phosphate batteries patent application began in 1997, can be seen that China lithium iron phosphate battery technology involved in relatively late start. However, we can see from Figure 1, presented a rapidly increasing trend of patent applications, (applications for the 2008 decline was mainly due to the year part of the patent application is still in closed state). Patent applications faster and the overall low number of patents, which is China's iron phosphate lithium battery layout of the basic characteristics.

Figure 2 shows the patent applicant before the 10 Top diagram. BYD Company Limited with 22 patent applications for the top spot, came in the first 10 applicants Shanghai Institute of Micro-system is only three, or even into the top 10 individuals among the applicants. Lithium iron phosphate battery technology in the field of domestic patent applicants scattered, mostly only 1-3 patents, long-term professional production of batteries BYD Company Limited is not big in the field of patents. Be concerned to grasp the core technology of several foreign companies did not appear in the first 10 Ranking. Chinese iron phosphate lithium battery technology, foreign applicants only Japan Sanyo Electric Co., Ltd. (2 has authorized), Hodges Co., Ltd. Yuasa (1 has been authorized).

In order to reflect China's current lithium iron phosphate battery technology patented composition, this paper analysis of IPC classification Ranking. IBM Laptop Battery Figure 3 for the IPC large groups classified by the top 10 Ranking diagram, the top three of the IPC words were C01B25 (phosphorus and their compounds), H01M4 (battery electrode), H01M10 (secondary battery and its manufacturing ), 90% of the lithium iron phosphate battery application for a patent belongs to the three categories. Thus, Taiwan's proprietary technology constitutes a major focus on lithium iron phosphate material, materials, preparation methods, the battery structure, related to the battery control in combination of a relatively small number of patent applications, and only H02J7 (used for battery charging or to the polarization or in the load from the battery pack to power the device) classification involved in the three patents. ThinkPad T40

China intend to fund Kenya's port construction China has sent signals, suggesting that they have an interest in Kenya's multi-billion dollar laptop battery large-scale projects part of the construction funds, the project will develop a port and transport corridor for vgp bpl8 , which may be the Sudan oil export to China to provide a new export routes.

Chinese Foreign Minister Yang Jiechi Wednesday in Kenya said that the Chinese government is urging domestic companies (many of which are state-owned enterprises), "to explore such a project on the possibility of cooperation with Kenya for ThinkPad T60 Battery."But he said that in an ongoing pending the outcome of the feasibility study will not make a formal financial commitments.

In 2008, Kenya to start talks with Qatar, which relates to Qatar to invest in port construction of ThinkPad T60 Battery, 3.5 billion U.S. dollars, in exchange for 40,000 hectares of farmland tenure in Kenya to grow crops, but the two sides did not reach an agreement.

Southern Sudan is currently dependent on pipelines, will be mined out of the oil to refineries and ports in northern Sudan, but the new export routes through FPCBP80 Kenya will break this dependence of FRU 92P1141.China has an abundance of oil fields in southern Sudan rights. Southern Sudan is expected to be held next year a referendum to decide whether to move away from a mainly Arab north. This referendum has triggered fears, fearing north-south conflict will break out again.

Last year, China continued to accelerate the pace of contacts with Africa, signed a series of access to mineral resources and building infrastructure for vgp bpl8 battery, vgp bps8a battery the new agreement, also used at a summit in November and promised to Africa over the next three years to provide 100 billion in new low-interest loans .

Yang Jiechi's visit is to visit five African countries for MacBook Pro 15 inch Battery, in Kenya, he will also visit Nigeria, Sierra Leone, Algeria and Morocco.Kenya hopes at popular tourist area Lahm (Lamu) the construction of a port and an oil refinery, as well as the accessibility of South Sudan and Ethiopia, FPCBP77 oil pipelines, roads and railways.

CCS is currently in the world the outcome of long march is only the first step. According to the International Energy Agency estimates that by 2050, CCS in order to alleviate a significant impact on climate change, at least 6,000 projects. Each project is stored in the ground each year 1 million tons CO2, but now only three projects of this magnitude FRU 92P1141. Can say that if CCS can not evolve in the next 20 years as a mainstream technology, the situation is not optimistic.

The deployment of CCS need to increase the cost of capital for MacBook Pro 15 inch Battery, capital expenditure depending on the capture technologies (pre-combustion, combustion, oxidation of fuel), but basically to separate CO2 from flue gas, compressed, the last transport. Preliminary estimates, the adaptation of technologies for trapping will increase by 50% to 100% of the cost.

The Government of Kenya cash-strapped, a person familiar with the Government's planning said that, according to government estimates of FRU 92P1141 battery , FPCBP68 the building of the port will cost four billion U.S. dollars, while the building of the "Northern Corridor," said the entire project will cost 20 billion U.S. dollars.

He said that, given the huge amount of money involved and the complexity of the project, the country will most likely rely on multiple sources of funding for vgp bps8a battery . Revealed late last year, sources said, China is negotiating with Kenya to develop this project. At that time Chinese officials in Kenya expressed disappointment at the lack of detailed planning.

Yang Jiechi Wednesday, said: "There are a number of studies are under way to clarify how much funding, funding sources, such as how to solve. These things have to be complete for Sony VGP BPS2A."Kenyan President Mwai Kibaki (Mwai Kibaki) Wednesday met with Yang Jiechi. FPCBP63 Kibaki's spokesman said: "We have not signed any documents. But they have so far shown a very firm commitment."

Hutchison, general manager of Shenzhen Electronics Co., Ltd. Greer Yanghai An entrepreneurial way of the wind and rain

Ten years ago, just leave the school, he took a blood cavity southward their dreams,Satellite 1900 but holding loss and disappointment playing with toys; Ten years later, the severe economic slowdown in the global situation, he Greer e Company contrarian, from the scale to the benefit and then to influence, a new interpretation of the "Shenzhen speed", the big waves in science and technology and information in the free game, enjoy flying.

Who is he? What's driving all of his Walk the Line? With a series of doubts, the reporter went on a crisp autumn afternoon, Greer Electronics Co., Ltd. Shenzhen, visited the young general manager Mr. Yang Haian. Laughing, he experiences the ups and downs, his entrepreneurial way deeply imprinted on our minds. As the saying goes: action rewrite life, the creation of values and expertise to win the future.

Preliminary examination chopper suffered setbacks in business

First saw Yang Haian, reporters some amazing, casual dress, thin build, looks hard to think that this is the current domestic and world influential notebook Satellite A60-662 battery R & D manufacture of high-tech enterprises head. Although the debut is only ten years, but he suffered the ups and downs and sharpen it is ordinary people's life unbearable.
In 1998, the Southeast Asian financial crisis swept through Asia, China's economic and social in this storm unscathed, and usher in yet another excellent opportunity for development.

This year, engineering graduates, he was assigned to the home mechanic to engage in a tea factory. However, after a period of time at work, full of passion Yanghai An original right of a decent life become more and more tired. Three months later, he decided to bid farewell to this life, so go south to Shenzhen, and a Senseio together, really want to find their own life.

Memories of this history, he said that Guangdong was not my first impression is good, Yanghai An smiled to reporters about a whole decade has passed a sad story. At that time young impetuous In his view, should be a graduate looking for work south parts easy simple matter, do not take a lot of money can find a job, so nothing to prepare and a friend went straight to Guangzhou, the thought that his friends, relatives and quickly can be stable, the results of realistic and they want the big difference Satellite A65 in the feel human indifference, the mingled a penniless state, twists and turns, decide, or go home. In borrowing money to buy train tickets back to Hunan, the Yanghai An initiated this pledge: never again in this life will no longer enter the Guangdong half-step.

Home later, Yang Haian serious reflection of the rather embarrassing trip to Shenzhen every aspect of life re-planning and positioning.

Ten years ago, the Mainland, black and white TV in the Mainland, particularly in townships and rural areas all the rage, in an unprecedented speed stationed thousands of families. Decided to start at home, he saw the potential, and so after a brief examination of analysis, he decided to use their own professional advantage to the local credit cooperatives borrow money for nearly 30000, found a shop in the town, open since the appliance repair shop.

With excellent professional knowledge and good aptitude, maintenance shops, fire up the business gradually, which gave Yang Haian boost in confidence. Satellite 2100 As market conditions continue to change and development, he does not meet a single appliance repair appliances began to plan take a wide range of fast road to riches.

At that time, due to the huge market demand, home appliances wholesale, retail and other kinds of stores springing up in his hometown to open to the rise. Yanghai An apparently saw the mast of the market, this piece of cake, and bones strong momentum so difficult for him to be complacent. As a result, the cause of the expansion and transformation seems inevitable to come.

Yanghai An idea is a great person, when his mind is how the net credit, bank lending more money, in order to build their own appliances wholesale department escort. After a period of planning and effort, this small dream did not suffer too much difficulty it can be achieved.

The rapid development of science and technology will certainly lead to rapid escalation of the product, the market reached a certain latent heat is often an unexpected crisis. Was not mature Yanghai An is the victim of this crisis. Saturated with black and white TV to color TV in the rise of this young man another heavy blow. 2000 Spring Festival eve Yanghai An Ministry of appliances wholesale batches of large and cumbersome, "guy" in the strong impact of scientific and technological revolution into a pile of nobody cares about the Fujitsu Laptop Battery "waste" in years that seems exceptionally busy Lunar New Year lonely and sad.

Over compensation and compensation for, I think it was due to the connotation of all BQ20Z80

Another idea is to build the capacity of statistics as an op-amp, the input and output is not the same,laptop battery is to compensate, and this is due to distributed capacitance, or offset voltage offset current exists. When the added compensation parameters are different, which it has phase are not the same, it is not the same as the distortion factor. how kind to maintain balance between input and output, you have to debug the designer. In other words, is how carried out in different frequency bands and under-compensated for compensation!
Over compensation and compensation for, I think it was due to the connotation of BQ20Z80 all. Otherwise, impossible to avoid learning function.
Through a series of experiments, added and pre-compensation owed to compensate, so that our management of chip reached a very good curve, how to compensate for? Using what methods of compensation, and only did people who can taste it Sweet's office.
Talk voltage accuracy problems. I think that there is no need to blindly nonsense their accuracy. Japan's Mitsubishi is also using the 37516 chip sampling of the 10 AD. Say 16-bit AD is what kind of concept? A super-sampling circuit Accuracy depends on the accuracy of the worst parts. For example: you use a 16-bit AD, but your reference to the source of the drift is greater than 30PPM / C, Tecra 8000
Accuracy not? Who can say that the precision of his own LDO can reach 5/1000? I think the Japanese still quite real. Therefore, I strongly recommend the use of engineers to write their own 10-bit precision of the measurement of IC. Sufficient. Do not waste of. If I want to, we should note that all parts meet, at least to use the box sampling resistor, right? However, the volume of box sampling resistor is too large.
Write a chip, of course, our interest is only fills also slowly improving its software, we must continue to be optimized. Of course, this process is quite interesting. There is one full of, it has been filled, the computer displays the percentage of even slower slowly decreased from 100%; a time that it discharges to 30%, and then disconnect the computer the next day, a look, is 0% of the. Later, when a careful analysis of programs is found that two variables, a change, but Another not changed.
A day goes by we can not use TI's chip design of Tecra 8100 notebook batteries, I was willing to help friends who are the best. Because the industry, Shang Hao faithful have been waiting for my things, do not give them too sorry to see or use is They hope to win. At the same time I am willing to help solve the problem the industry cost pressures on the side of one arm. let the Chinese people make more money.
I am also a faithful application of TI, is also on the TI have profound emotions. My last of my chips into the BQ series of TI's brother. As to whether it deserved, we should wait until our evaluation of the company's customers. Once A friend of mine told me: quickly made, TI is too cattle, and now is the time TI lesson. I do not agree with a TI approach, I think it is applied, it is necessary to the user. the user there is a problem to be solved in time. If I were TI's FAE, I must have used something unconditional devotion to the user. Although the market far from ideal, however: the money is not, Tecra 9000 and human in the. most of the people of high caliber engineers, they received your favor There are certainly opportunities to be reported Yongquan phase.
Lastly, my goal is to allow the company where I can use all the products of our own chips, to let my friend use my chips. I have always felt a thing to do is to do it, rather than to the other Objective. this time all of the debugging aid of TI are the EV2200, empty after the host computer Tecra 9100 to write a program to download the procedure. I have always thought that is just normal before they can do their own thing. Finally, I think we can do well it is.

Notebook Battery Meter complex (Principles of articles)

BQ2060 chip from exposure to the application of the present BQ208X, PS501, laptop battery and those who have and the mistakes I have and I blame the chip for a domestic home, I have experience with the application. I have always thought that was a battery meter chip is not difficult, it is difficult is the battery, the lack of appeal that an amount too low. to the present date, I have not found a good measurement statistics chips. the facts are as follows:
PS501 not be regarded as a good chip, in addition to rumors rumors soon to be discontinued, but also there are many fatal flaws, such as: EDV in the design of the voltage and capacity must be used when the look-up table. Look-up table method is a different temperature conditions different load conditions, get a battery fully discharge end of the discrete points. In fact, the battery on the laptop battery, with their real environment and the user can not be tested using the environment to. In other words, terms, only about the simulation. and that these data only take into account the situation of new batteries under the conditions. If the battery is used, after a hundred times how to do? which it will have moved all of the curves. Therefore, this method is not desirable. So I have always been skeptical of the PS501.
For the TI chip, is a proud giant things. TI algorithms I also study a lot of times, even by some within TI, playing a "secret" documents two times in the study. Satellite A10 Analysis to analysis to is confused and does not have a convincing formula, ambiguous, and even some of the value of experience. did want to emulate their algorithm to write an own capacity management chips, finally set aside their formula up. TI is a noble chips, is unpredictable in. on the Internet, it has been called the **** type of mix (should be one of my friends say). Of course, some people can do the chip to make money it should be. But the people disappointed that some applications were Yan-Yan's method class. ask them a question they do not know is that they do not know, or so-called secret, the answer is usually in the foreseeable future. funny thing is, when you made a number of electronic E-mail to TI's headquarters, when the Americans went so far as some valuable information to you without reservation. So, apart from technology, a conservative Japanese, Taiwanese, is TI's China office person.
I have been trying to write a good chip for their own. I used the resources of the previous and present the company's resources, has had initial success. Basically I am familiar with the TI interface, with the accustomed style TI's software and programming model, so I did the chip should be to achieve the goal of TI. If one day I chip applications mature, I must break the monopoly, to me there is a strong support for households. I think technology will always be endless, do not want to Some companies,Satellite A100 like the equipment, ten years does not change a board, which is a non-progressive company; to continuously exchange applications. superior product application is based on the user's to improve on.
Speaking of capacity management, in fact, is essentially a "model lake" estimate algorithms. Online is not to say, "blurred" algorithm do? So-called "blurred" algorithm should be based on absolute conditions, and there is no accurate data and conditions, do not vaguely by Canadian.
The nature of capacity measurement is to accurately tell the user: how much power is left. This is the essence.
Therefore, the design capacity of a good manager, how much power is left, is a strong section title. I have read literature at home and abroad, checking all over the company's calculation methods. Including the United States die, several companies in Taiwan measurement methods, some of Taiwan's university doctoral thesis. generally stays in the look-up table method. there is no breakthrough in the discrete curves TI calculation.
Recently introduced BQ20Z80, is said to be a very magical chip may be based on self-balancing resistance. And can avoid calibration. One great myth about this chip, I have been struggling to thinking, in the end is how to test it, in the end estimate how the capacity of it? recently read some resistance tester line, the Maosaidunkai. To put it plainly TI's resistance, Satellite A70 that is, the internal electromotive force batteries only. test EMF Who is not? open book there! electromotive force and capacity of there is a corresponding relationship!
However, to avoid learning how he come from?
Through our development process, the hard exploration, our curve and the theory is close to the TI algorithms. Mold release charge curve is like a decent. There was no strong pause or change, basically satisfactory results . I was thinking: TI's idea is really clever, TI is a clever giant 呀.
I simply referred knot algorithm, as it is not it. GAS We are temporarily put it in the presence of an object can change, it may be as the temperature changes or discharge rate of change objects. It is subject to change, and then with the discharge lines, it will become granulated into powder state, Satellite A75 into a liquid. ultimately released capacity is not the same. the capacity to imagine it as temporary as a matter of volume.

Domestic compatible laptop battery 1st Round - first meeting
2 years to accompany my original notebook battery, and finally generating a 5-minute time to laptop battery submit his resignation to me the report. For the computer peripherals do not understand me, and had captured over the weekend knowledgeable brother to the digital store and bought the batteries. To go before I made up my mind to give me books with a pink sony original batteries, but a Look at the price of original let me speechless, thinking that these small Japanese really would make money, the parts also so expensive, simply say this: sinister ! !
Look at my teeth look like my brother, laughing at the same time worshiper of foreign things I purchased my 180-degree direction of the major adjustments - made compatible with laptop batteries.
Brother introduced Feihong eagle is a brand of notebook batteries, the box to do it very carefully. Casing clean, flat no indentation, open the battery box was soft sponge wrapped in neat, JANSEN, battery pack is also outside of professional static bag, battery shell smooth Seamless, feeling fine ... ... Oh, is quite formal 呀they looked very agreeable I like. Girls are like the appearance of animals, to see such shiny appearance, the hearts of the Chinese-made brand battery is compatible with the ill feelings immediately dispelled by half.
2nd Round - cost-effective to fight
Cool, cool! ! Kind of animal in nature to see my brother, hastened to stop me to continue to drool.
Price! Yes, the price is how like? PA3291U-1BRS Store's answer surprised me! Would not you? Only one third of the original?
Service-na? Actually there is one and a half!
Have a product certification and the international inspection reports Mody? I took out store CE certification, the United States UL safety certification and 3C certification.
Procedures are still a full-ah, but the psychological or the right price with the original, when there are too many gaps in the offing. Friend was already blue-moon to help me buy a piece of notebook batteries. When I was about to stop the shot with a "is a mule is a horse, pull out yo." Put my words stuck in his mouth.
3rd Round - practical application, my battery will not explode?
I can not wait to bring home a new battery according to the notebook, but fortunately, Fei-Ying laptop battery in terms of workmanship, or both, and in terms of the degree of matching the original battery did not make any difference.
"I can go home it?" "No, resolutely not work! Case if the explosion of how to do? You have to stay with my charge and discharge time I can let you go!!" PA3506U-1BRS Laoge reaching helpless surrender.
End of electrical impulse, I picked up a stopwatch exaggerated start to discharge time. Feng watching the latest movies, shows battery capacity is 29%.
"Yes, right?, What say? This time relieved it, worshiper of foreign things little girl!" Laoge proud smile at me.
"But have not previously heard of this brand that way?"
4th Round - in-depth exploration in preparation for defections Laoge
I have been a great importance to the brand, PA3591U-1BRS so a search online a bit so that my brother proud of this brand. Feihong Eagle brand original laptop batteries behind an area of about 2,500 square meters, existing staff of more than 200 people, and have a professional, high quality, efficient R & D team, R & D department staff about the management of one-third of the total number of standardized production base. Prior to overseas markets such as Europe and the United States is committed to developing and highly praised.
Hey ~ ~, finished finished, defections Laoge the complete failure of the plan! ! Portege 4000

the energy sector is becoming the new development direction of the two

In fact, the new energy stocks in the A-share market has been in operation for five years, PA3084U-1BRS the Pioneer is the current growth trends remains optimistic about the performance of Tianwei Paul changed, its solar energy industry is still in the ascendant. But, during the short-term gains because of the lack of subject matter is too large or because the catalyst, causing stock prices short-term volatility pattern emerged.
However, the new energy is now becoming the two major new impetus. First, the construction of the information charging station. Less than two weeks time in the near future, Xi'an and Tianjin Electric Power Corporation have announced that this year, determined to build four and five electric vehicles charging stations. Analysts believe that the State Grid Corporation and China Southern Power Grid Corporation has begun low-key electric vehicle charging stations as a strategic focus, and this year is a large-scale cloth points across the country. They hope to occupy in the new era of energy vehicles Heights,PA3399U-1BRS to replace the battery charging station the status of the oil giant's gas station has become the most important position accounts for the energy giant. This will undoubtedly mean that more environmentally-friendly electric cars expected to grow from concept to practical application, and therefore expected to be the new energy stocks the new Zhang Sheng opportunity.
Second, smart grid and other references are also densely together recently, the National Grid, China Southern Power Grid appears in the use of special high-voltage electricity transmission method as an entry point to all aspects of the smart grid investments. The smart grid, once into the substantive operational phase, would mean that wind power and other new energy business will exceed the development bottleneck, because the current background of the traditional electricity transmission grid, the grid operators are reluctant to access a large-scale wind power grid. Smart grid can solve this problem. Thus not only promotes wind power and other new energy business development, but also to make super-capacitors PA3395U-1BRS and other new energy sources to obtain significant new business development, so it is expected in the near future to open a new energy business development.
From past trends, the new momentum stocks tend to give new energy to bring the new hot hype. For example, in 2005 the solar Tianwei change security operations, and then start to appear on the rapid development of wind power equipment as well as in the past year more than a hybrid electric vehicle concept, the hype for the new energy unit entered the stream of Zhang Sheng energy.
On the current situation is mainly reflected in two points: First, the construction of charging stations, and second, super-capacitors, electrolyte and other business development direction. With the expansion of the size of electric cars, super capacitors, lithium batteries or other battery electrolyte demand leaps and bounds, the possession of these businesses or subject matter of these businesses is PA3250U-1BRS expected to stocks into a steady stream of power, such as copper peak electronics, the new-chou state, Jiangsu and Cathay Pacific.
However, the new industries with high growth, but also has strong uncertainty. Therefore, in actual operation, only recommended a stronger investor risk tolerance to be tracked. One otter Xun, the new state-chou, Shanshangufen and other firms to actively track, which also has a nuclear power Ott Xun business performance drivers, the new-chou state because they have the market share of lithium battery electrolyte to enhance the performance of the rapid promotion of force, Shanshangufen Bank of Ningbo has a stake as well as existing garment business arising from cash flow support, with a certain margin of safety. In addition, for the same side all-shares, etc. The new energy business developers can PA3356U-1BRS also be a positive track.

Asus is Working on An EBook Reader There¡¯ve been rumors floating around for months that Asus is working on an eBook reader. laptop battery But according to the Times Online, it¡¯s not going to look like any other dedicated eBook reader on the market of VGP-BPS2A. That¡¯s because instead of going with the typical e-ink display, Asus is reportedly going with a bright, full color OLED display that will be able to handle magazines as well as books (and presumably newspapers and/or web sites).

According to the Times Online, the tablet will features a 6 inch screen, support WiFi and 3G, and be able to play Flash video. Oh yeah, and the battery is supposed to be good for up to 122 hours for VGP-BPS8 battery .Blagojevich was arrested Dec. 9, 2008, on charges that he'd sought to sell Obama's former U.S. Senate seat for a personal benefit -- including trying to get a presidential Cabinet post for himself. Blagojevich subsequently was impeached and booted from office.

No word on what kind of processor the Asus eReader would use, but my money¡¯s on it not being a Core i7. Think ARM-based chips like recent entries from Qualcomm to A1175 battery , Freescale, or Marvell. I¡¯m still not sure how you can expect to get that kind of battery life out of any processor with an OLED display, but for all we know, the 6 inch tablet will have a 3 pound PA3191U-1BRS battery.

The two companies have signed an "agreement in principle," according to Spring Design. The Borders store, which will be available on Borders.com and and via a Borders mobile app for VGP-BPS8 battery , will feature more than 2 million titles.

"The combination of Borders' leadership in the book industry and Spring Design's innovation and experience in consumer electronics will create a world class service for eBook readers to sony vgp bpl8 ," Dr. Priscilla Lu, chief executive officer of Spring Design, said in a statement. "This partnership delivers one of the critical foundations of our business growth going forward."

"Our agreement with Spring Design represents another step in our digital strategy, PA3166U-1BRS which continues to focus on offering book lovers-including our more than 35 million Borders Rewards loyalty program members-high quality content on the device of their choosing," said Borders Group Chief Executive Officer Ron Marshall for VGP-BPS2A. "We look forward to bringing a world class eBook experience to Alex users."

Sony opted to put its muscle behind LCD TVs with frame rates twice as fast as conventional LCD sets. While this feature was a tough sell in 2-D televisions, since the picture improvement isn't obvious for VGP-BPS2A,VGP-BPS2 the technology is critical to displaying natural-looking 3-D images. Panasonic also sees a chance to revive faster-responding plasma displays, which have lagged behind brighter LCD televisions.

Claypool said he only briefly considered a run to fill Emanuel's seat and had no role in any plan to keep the seat warm for the top Obama aide's eventual return.Blagojevich, it turned out to vgp bpl8 battery , did not have the authority to appoint someone to replace Emanuel.Claypool's fellow county Commissioner Michael Quigley ended up winning the seat in PA3331U-1BRS Congress.

Alex will be available starting Feb. 22 for $359 on www.springdesign.com. The device made its official debut this week at the Consumer Electronics Show (CES) in Las Vegas.No word on pricing for ThinkPad T60 Battery, but we do have a model number to keep an eye on: The Asus DR-570. Rumor has it that the device should be available before the end of the year.(PA3098U-1BRS laptop battery)

Keyboard and Touchpad

The full-size keyboard on the 8440w Presario V5000 PA2487U battery is a nice update to the keyboard seen on the last generation of EliteBooks. The new keyboard uses flat, semi-chiclet style keys and provides excellent spacing between keys for typing. Each key features the "HP DuraKey" finish which is a highly durable textured finish applied to each key to give the keyboard a nice matte appearance and prevents the "shine" that appears on old keyboards after the buildup of dirt and oils from your fingertips. As previously mentioned, the Magnesium alloy keyboard tray features drain holes to help direct accidental spills away from the delicate electronics inside your laptop pavilion dv1000 battery.

The individual key presses are quiet without loud clicking sounds as you type. The depth of each key press is excellent, though some people may dislike the flat, chiclet-style keys. Overall the keyboard layout pavilion dv2000 battery is extremely nice for a 14-inch business laptop.

The Synaptics touchpad is very responsive to my touch with a scroll zone on the right side that works exactly as it should. Granted, the touchpad laptop battery is a little small for a modern notebook, but it's not too bad overall. The matte touchpad texture is okay, but doesn't deliver the same high-quality feel as the rest of the notebook. The rubberized touchpad buttons are about the right size and feel quite nice pavilion dv4 battery when pressed. The only problem I have with the touchpad buttons is the fact that they are hinged rather than simple press-down buttons. The buttons work by "swinging" down from a hinge located at the top edge of the button. This means that if you press the top edge of the buttons nothing happens. You have to press the middle or bottom of the buttons so that the buttons can swing down from the hinge. I don't have any idea why HP did that.

On a brighter note, the trackpoint/touchpoint is easily one of the best we've seen this side of a ThinkPad pavilion dv5 battery. If you're someone who like using the touchpoint then you're in luck with this machine.

Ports and Features

The 8440w features a great number of ports on pavilion dv7 battery all sides so let's take a brief tour. Left side: Here we see the heat vent, three USB 2.0 ports, FireWire 400, audio jacks and the ExpressCard slot. Left side: Here we see the heat vent, three USB 2.0 ports, FireWire 400,PA3107U-1BRS audio jacks and the ExpressCard slot. Rear side: The security lock slot, battery, hinges, power jack, DisplayPort, and VGA out. Front side: Speakers, memory card slot and screen latch release.

Performance and Benchmarks

Our EliteBook 8440w came with the new Intel 620M Core i7 processor, clocking in at 2.26GHz with four cores ... although our test system ran a little fast at 2.67GHz. As is common with workstation-class machines, the 8440w features NVIDIA pavilion dv4000 battery Quadro graphics in the form of the Quadro FX 380M with 512MB of dedicated RAM. This gives the EliteBook significantly more power than a typical business hp pavilion dv2000 battery notebook and a jaw-dropping level of performance with only a modest cost to the battery life. A 320GB 7200RPM hard drive was also included, which helped applications load without much lag. This notebook should easily exceed the expectations of all but the most demanding professionals in terms of graphics performance.

Heat and Noise

During normal use (browsing the web or working on a text pavilion dv6000 battery document) the EliteBook 8440w remained quite cool and very quiet. PA3383U-1BRS The exhaust fan wasn't audible except when running performance benchmarks or stressing the CPU and graphics. You won't have to worry about bothering coworkers or clients with unwanted noise coming from your laptop in a quiet office.

Finally, we recorded the following external temperatures using an IR thermometer after running two consecutive PCMark05 benchmarks. This should serve as an indicator of how hot the notebook will get after about 30 minutes of serious use. All temperatures are listed in degrees Fahrenheit. It's obvious that the bottom of the notebook near the RAM and CPU heatsink are the hottest parts of the notebook pavilion dv8000 battery.

Battery

HP offers the EliteBook 8440w with your choice of either a 6-cell or PA3384U-1BRS 9-cell Lithium-Ion battery. The pavilion dv9000 battery life of the standard 6-cell battery is good and the 9-cell delivers almost 1.8 times the battery life of the standard battery. During our timed tests, with the laptop set to "balanced" mode, wireless active, and 70% screen brightness, the 8440w lasted for 3 hours and 57 minutes. Battery life with the 9-cell is closer to 7 hours. Battery(pavilion zd7000 battery) life can also be extended using the "power saver" power profile in Windows 7 ... or you can purchase the 8440w with the "slightly" lower voltage 2.4GHz Core i5 520M processor.

Conclusion

The EliteBook 8440w marks the beginning of a new class of mobile workstations. This durable 14-inch notebook packs all the processing a graphics horsepower you're likely to need and does it for a reasonable price. Although $1,649 isn't exactly pavilion zv5000 battery cheap, this is more affordable than many other 14-inch business notebooks with lower performance numbers. If HP added a larger touchpad and better touchpad buttons then this mobile workstation would be absolutely perfect. As is, the 8440w is still a masterpiece among 14-inch business-class notebooks PA3285U-1BRS and is an obvious Editor's Choice

order to achieve the commercial, you may also need to 10 years. Large-capacity lithium - air batteries is not a new concept, because it has neither popularity there are fatal flaws, laptop battery Japan's Research Institute to overcome this difficulty, but in
Carbon reduction, for human well-being, it is definitely not a tall order, but for the global automotive industry, it is a difficult task.
Is well known, lithium-ion batteries are widely used in mobile phones and notebook computers, is also already the next generation of plug-in hybrid and electric vehicles of choice. It is the density of car batteries than any other higher power is more adequate, but also more expensive, are subject to battery capacity, charge the driving range is still far enough. Listing of the upcoming 2010 Chevrolet Volt hybrid car If you use only batteries, can travel 40 km.
Although there is still room for improvement, but the potential for lithium-ion batteries are still limited. Generally agreed that in order to achieve the popularity of electric vehicles, energy-density required to achieve the present level of about 6 ~ 7 times. So, in theory, is far greater than the energy density of lithium-ion battery Lithium-air battery cause for concern. While still using an organic solvent, but it constitutes a completely new greatly enhance the energy density of batteries.
Lithium - air batteries is not a new concept. Because the positive use of oxygen in the air as the active substance, in theory, the capacity of positive density is infinite,PCG-R505 can increase the capacity. In addition, if the use of lithium metal anode, theoretical capacity than lithium-ion rechargeable battery to improve a few.
But why lithium - air batteries so far none of popularity? Because it was fatally flawed, that is, reaction products of solid lithium oxide (Li2O) accumulate in the anode, so that the electrolyte had been cut off contact with the air, leading to discharge stops.
In February 2009, the Japanese Institute of Industrial Science and Technology Interface energy technology research department of energy technology research team leader Zhou Hao Shen, and Japan Society for the Promotion (JSPS) for foreign researchers Yonggang special co-developed a newly constructed high-capacity lithium-air battery.
Will be divided into two kinds of them through the electrolyte to resolve the above issues. In the negative (lithium) side of the use of organic electrolyte in the cathode (air) side of the use of water-based electrolyte. Set between the two electrolyte lithium-ion only through the solid electrolyte membrane, to divide them. This will prevent the electrolyte mixture, and to promote the battery react.
Cathode is used in combination with the electrolyte containing organic lithium salt electrolyte. Although we can not abandon the organic solvent, but it limits the use. Water-based alkaline electrolyte cathode using water-soluble gel, and after the micro-based catalyst for the formation of oxides of carbon and low-cost combination of the positive.
In lithium - air battery, because PCG-V505 the discharge is not the reaction of solid Li2O, but easily dissolved in the aqueous electrolyte in the LiOH (lithium hydroxide). Accumulation of lithium oxide in the air after the electrode does not lead to work was stopped. Water and nitrogen through the solid electrolyte and will not next door, so there is no place with a lithium metal anode reaction risk. Moreover, in charge, if the configuration-specific positive charge, but also conductive to prevent charge-induced corrosion and aging of the air electrode.
Experiments show that in order to 0.1A / g discharge rate of discharge, the discharge capacity of about 9000mAh / g, while the previous lithium - air battery discharge capacity of only 700 ~ 3000mAh / g, can be said to achieve a substantial increase in capacity.
In addition, if the use of aqueous solution to replace the water-soluble gel can be in the air to 0.1A / g discharge rate of continuous discharge for 20 days, the discharge capacity of about 50000 mAh / g (air-polar unit mass), higher than the original digit. As the lithium metal battery capacity than lithium-ion battery had a high a number, so the value of a total of more than lithium-ion rechargeable batteries high double-digit.
Now, thanks to a high performance aqueous solution, and in ease of use even better on the gel, the scientists decide whether the future PCG-Z505 need to consider which of these two, one for development.
Understand that this technology could also be considered with a simple to use rechargeable batteries of different ways. If you do not recharge the battery, but by car to replace the base of water-based electrolyte cathode, card boxes, etc. in order to supply the lithium metal anode, cars waiting time can be achieved without charge, immediately moving.
Moreover, through the recycling of used water-based electrolyte, lithium metal, electrical means to regenerate, but also continue to serve as the battery anode fuel cycle to use, to avoid other pollution. Lithium - lithium air batteries can be said that the new fuel cell as fuel.
Scientists believe that the performance of lithium-air batteries, lithium-ion batteries 10 times, can provide the same energy and petrol. Lithium-air battery to absorb oxygen from the air charging, so the battery can be smaller, lighter. Many laboratories worldwide are exploring this technology, Toshiba Laptop Battery but without a major breakthrough, in order to achieve the business may also need to 10 years.

The Key Of Vehicle Efficiency Help To Improve Battery Technology

The key to improving electric and hybrid vehicle efficiency/driving range is to improve VGP-BPS5 battery technology of Fujitsu lifebook t4210 battery. As such, many of the world's largest automakers have paired with battery makers to improve the technology.

As more and more hybrid and electric vehicles are announced and make their way to the U.S. market, there is an increasing demand for batteries for the vehicles to Fujitsu lifebook t4220 battery. The demand in some instances is exceeding the capacity of some of the largest battery companies. A123 systems has announced that it is set to expand its battery making capacity significantly.

A123 makes battery packs for several automakers including Fisker and Chrysler. Examples of such activity include today's announcement of a newly established strategic VGP-BPS8 relationship with Fisker Automotive for vgp bps8a, our recently signed joint venture with SAIC and expansion of our electric grid customer base just to name a few."

A123 plans to expand the production capacity of its Livonia and Romulus battery plants beyond their original capacities. The new Livonia facility is 300,000 square feet and is set to open by the middle of 2010 for Fujitsu lifebook t4210 battery. A123 had the capacity to build 169 megawatt-hours of batteries as of October 2009. By the end of 2010, the battery firm will have a manufacturing capacity of 360 megawatt-hours.

Autoblog Green reports that the 360 MWh capacity is VGP-BPS9 enough battery packs for 24,000 plug-in hybrids with 15 kWh batteries or 320,000 conventional hybrids with 1.1KWh battery packs. With A123 providing battery packs for Fisker, the new capacity may prove too low even with the new expanded capacity of VGP-BPS8. Fisker expects to sell 15,000 of its Karma plug-in hybrids each year.

David Vieau, President and Chief Executive Officer of A123 Systems, said, "The combination of proceeds from our recent IPO and funding support from the DOE has provided A123 Systems with the capital necessary to execute against our expansion program for vgp bps8a ,VGP-BPS8 Our strategy is to deploy capital as we see customer demand developing, and we are VGP-BPS10 encouraged by recent developments and the momentum within our overall portfolio of customer relationships across our key target markets.
