Thermal runaway is the battery in charging the heat generated in the process is not released in time, temperature and chemical reactions between the formation of a positive feedback gets out of control. Thermal runaway of the battery is devastating, resulting in battery case deformation caused serious battery explosion. Thermal runaway because the room the ambient temperature exceeds 45 ℃, high temperature float voltage is too high (without temperature compensation), the charge current exceeds the design value (more than 2.5C10).Toshiba pa3399u-1brs battery  TOSHIBA PA3399U-2BAS Battery  

Sulfate is generated in a very white-board hard lead sulfate crystals, particle relatively large, active low,HP PB992A Battery, charging hard to get into lead sulphate as active substances, resulting in battery capacity decline or failure. Hydrochloride of the reason is that the battery in the installation set aside a long time before storage (more than 3 months), persistent or recurrent excessive discharge excessive discharge or a small current deep discharge, the ambient temperature is too high or too low, often inadequate and does not charge a regular basis are sufficient.

Years, four million mobile phone battery scrap the proposed processing center in Chengdu, "detoxification"

Recently, the reporter learned from the Municipal Environmental Protection Bureau, Chengdu,Laptop Battery the proposed hazardous waste processing center has recently been selected owners of units are currently located. The cooperation between Chengdu and the Changhong Group, Waste Electrical Treatment Center has recently initiated negotiations, the project most likely settled in Jintang County Huai River Town. By then, most parts of Sichuan, Chengdu, as well as waste electrical and electronic products, there will be disposal of the Department.
Annual waste of about 4 million mobile phone batteries

"Also for mobile phone batteries, this battery waste, together with the ordinary rubbish put fear, let alone throw them powerless place, you should pay attention to the media about the whole thing." Recently, Chengdu Jinjiang District near the East than the field of property management of a residential area Members complained to reporters that an increasing number of electrical and electronic waste, the do not know what to do. TOSHIBA PA3421U-1BRS Battery TOSHIBA

But in fact recovery of batteries is now being done is no longer handled.

It is understood that a cell phone battery pollution load equivalent to 100 ordinary dry batteries can be seriously contaminated by about 60 million liters of water, equivalent to an individual's life and the amount of drinking water. The popularity of mobile phones according to 70% of the amount of calculation, Chengdu, there are about 8 million mobile phones, if a battery replacement every two years, then every year about four million mobile phone batteries obsolete. Provincial Environmental Protection Office, who introduced similar to the discarded cell phone batteries, usually requiring that the manufacturer recall. The question now is, few people would surrender their waste battery manufacturer, PA3456U-1BRS Battery   or do not know how to return the factory.

 

    Third, the impact factor in the base station battery operating life

Remote location of many of the base station, AC power supply instability or frequent power outages, or even simply do not alternating current; no air conditioning or outdoor base station sites, the ambient temperature is high; site, remote and quantity, can not be refined to maintain. These are the base station battery working conditions of the environment.

China's base station batteries through the analysis of the damage, collecting Xinjiang, Zhejiang, Shaanxi and Yunnan provinces battery damaged specimens analyzed in conjunction with overseas Vietnamese, Egypt, Pakistan, Ethiopia, the base station power can corrupt data, we have come to affect the operational life of battery There are the following factors:TOSHIBA Pa3356u-1brs battery 

    (1) AC frequent power cuts

Frequent power outages, power outages a long time, outage time irregular, so that frequent battery charge and discharge, or the base station simply do not alternating current, through the turn of diesel generators and battery power, is caused by rapid decline in battery capacity and shorten the life of a major reasons.

The base station blackout frequency is too high, power outages several times a day, or even power outages for several days straight, so that the base station after the battery discharge fully charged yet another case of discharge, battery charging time is owed to the state. As has occurred many times due to continuous charging, HP PB994A Battery, battery capacity will result in cumulative losses, sulfate of aggravated battery capacity will decrease in a relatively short period of time, its life will be quickly terminated. Satellite a10  battery

    (2) The battery is stored too long

Exist in the process in the storage battery self-discharge, if the time is not added, there will be the phenomenon of sulfate. If this is the absence of timely improved battery capacity would be reduced or even damage can not be used. Battery in the storage process, the ambient temperature also has great influence on the capacity, as shown in table 2.

China Space Expo vehicles equipped with power battery

Reporter on the 24th from the Shanghai Aerospace Power Technology Co., Ltd. Fujitsu Laptop Battery was informed by the company's commitment to the development of the Shanghai World Expo VIP automotive power lithium-ion battery and Expo will be demonstrated on the fast charging electric vehicle batteries project has now been carried out loading sports verification, will be put into use at the Shanghai World Expo.

Meanwhile, the Shanghai Aerospace Power Technology Co., Ltd. An annual output of 15 million (for 10000 assembly of a platform when an electric car) lithium-ion battery Toshiba pa3399u-1brs battery production line are debugging, and is expected in June this year, mass production capability.

According to reports, in February 2009, the China Aerospace Science and Technology Corporation Shanghai Academy of Spaceflight Technology affiliated Shanghai Institute of Space Power establishment of the Shanghai Aerospace Power Technology Co., Ltd., specializing in vehicle power lithium-ion battery and power management system development and production, in April that the absorption of high-tech industrialization key projects in Shanghai, Fujitsu FPCBP77 Battery "the new energy vehicle power lithium-ion battery project", was officially launched vehicle lithium-ion battery industrialization. That year in July, the Shanghai Aerospace Power Technology Co., Ltd. signed the first phase of four shareholders of 90 million yuan investment agreements to work together to build internationally competitive, from the raw materials, batteries, battery management system to the battery of the new energy vehicle equipped with power lithium-ion battery industry chain, to form the key components of China's new energy vehicles own industrial system.

In accordance with the development plan, the Shanghai Aerospace Power Technology Co., Ltd. to 2012 years ago, the registered capital of 4.5 billion yuan,Fujitsu FPCBP68 Battery total investment of 700 million yuan and above, forming an annual output of 100 million when the vehicle power lithium-ion battery production capacity; to " Shier Wu, "end with a total investment of 45 billion yuan to build international advanced new energy vehicles and power lithium battery industry chain and the formation of one million vehicle battery power system-level matching capacity.  TOSHIBA PABAS076 Battery  

BaseBuild Battery From the current situation, widespread decline in battery capacity too fast, short-life issues, just 1 to 2 years battery capacity of only a nominal capacity of 30% to 40%, some only 10% to 20% , and most of the base station battery after a 4 years running, Hp laptop battery its capacity is only 50% of its nominal capacity of about fall far short of its design life, and ExchangeBureau stations compared to similar batteries, their life is also greatly reduced. In this paper, the base station Damage to the battery during the operation carried out an analysis of the reasons put forward to extend the battery life of the base station approach.

 

    First, the definition of battery life

Battery life generally refers to floating state of life. For the non-floating mode of operation of the battery, its life cycle of discharge from the number and depth of discharge measured in two dimensions, as shown in Table 1. It is not simply in order to be able to use for many years to measure battery life.

For the number of battery discharge cycles, the battery must be sufficient after discharge electricity, enough power to at least 24 hours charging time (based on YD/T799-2002 requirements). For the charge is insufficient, its difficult to determine the number of discharge cycles, will certainly be lower than the data described in Table 1.

Depth of discharge of the battery life impact is very large, the deeper the depth of battery discharge, the fewer the number of recycling, as shown in Table 1, and therefore should avoid the use of depth of discharge.PA3166U-1BRS battery  PA3176U-1BAS battery 

    Second, battery end of life factors

For valve-regulated lead-acid batteries, there are four kinds of failure modes: positive plate corrosion,HP 398876-001 Battery, water loss, thermal runaway, sulfate. One positive grid corrosion due to alloy Improvement in the corrosion rate is very slow, generally 10 to 15 years.

Water loss are more ways: throttle design unreasonable, frequently open; the power of the batteries are rechargeable frequently; the ambient temperature is too high. Which is the most important factor in high-temperature, high temperature will accelerate the pace of battery water loss, leading to decreased battery capacity. With 25 ℃ as the benchmark, when the battery operating environment up 10 ℃, life expectancy reduced by 50%, as shown in Figure 1.

lithium batteries power the concept of security and life

2.1 The root causes of insecurity in the battery

When the battery is a part of the deviation occurs, such as when the internal short circuit, high-current discharge and over-charging, it will generate a lot of heat, causing the battery to the system temperature increases. When the battery system and reach a higher temperature, Normal 0 7.8 磅 0 2 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Toshiba PA3084U-1BRS battery  Toshiba PA3098U battery   will lead to a series of side-effects, so that the battery produces heat damage, due to battery flammable liquid electrolyte, so the worst case, the battery would catch fire [1].

In the case of the non-normal use (such as overcharge), lithium-ion battery anode is likely to surface, the electron, as a lithium metal precipitation, and gradually gathered into a lithium dendrite punctured diaphragm, connectivity is negative, causing the battery internal micro-short. Lithium-ion batteries used in high compression, high-boiling point organic electrolyte. In the short-circuit, over-charging, high temperature and other non-normal use conditions, the lithium-ion battery internal temperature will rise, the electrolyte may be broken down into a lot of gas will be generated within the sealed housing relatively large pressure. Once this pressure large enough to break through the battery case, rupture occurs, and even lead to burning or explosion [2]

In China, car battery replacement after the recovery of more forgotten corners. A repair shop in the 4S said: "The car battery can be recycled. 4S store in the user's car battery replacement, the unified collection of specialized batteries sold to recycling companies, one can sell a hundred million." Regret is that the owner was told that each time only for a new battery, do not know the replacement of the old batteries can be recycled.

And domestic users of automotive batteries automotive knowledge and understanding of diametrically opposed, in Europe and the United States and other auto power, auto batteries already been placed in the supermarket shelves, and oil, tires, like the three cars side by side to become vulnerable one piece. A fire or a car suddenly broke down there Dabu Zhao circumstances, the owner will be obvious to determine where the problem lies immediately removed. In these countries, can often see such chic scene: the car owners driving a car to the supermarket shopping, by the way forget to buy a battery, to return home to open car cover, replace the battery themselves. This is abroad, is not something new in. In the United States, there are four or more into the hands of the owners to replace their batteries.

"Owner should cultivate a good sense of the car battery consumption, in order to protect their own rights." An appeal to the industry.HP EV087AA Battery, He said: "the current situation, China's auto battery market, has just started, most owners do not realize that automotive batteries are not only start the car directly to the energy, but also for the growing automotive electrical current to provide a balanced guarantee. Leading to frequent car broke down halfway there the embarrassment caused to the owners a lot of unnecessary trouble. Therefore, we owners should be aware of the importance of automotive batteries. "PA3107U-1BAS battery  PA3107U-1BRS battery  

Pleased to see that some well-known domestic companies have started to focus on automotive batteries to guide China's auto battery consumption, and thus lead China's automotive battery industry. As the world's top 200 companies, has the world's automotive battery market share nearly 35% of the industry leader, Johnson Controls has already begun such actions. "We hope that through our efforts to help China's auto users to have a correct knowledge of the car batteries and consumer outlook." Johnson Controls Power Program (battery) of China, Mr. Huang, director of sales and marketing, said in an interview,HP Pavilion dv9000 Battery(hp dv9000 battery), HP EV087AA Battery, HP EX942AA Battery "We understand the owners the case of a sudden Dabu Zhao Jiao set fire flawless mentality, so we hope that through the efforts of Johnson Controls for China to bring a healthy and positive life vehicles as far as possible to avoid the occurrence of the above. "

It is understood that, in order to effectively guide the consumer to promote industrial development, Shanghai, Johnson Controls has established a nationwide 20 Valta flagship store / image of the shop, and will be established throughout the country next year in 200 outlets. HP EX942AA Battery "We hope that in this way is so that people could feel that VARTA service and care, understanding and knowledge of our consumer culture advocated by the car battery." So, said Mr. Huang Zhiyong.

 

High-power charging and discharging of the large-capacity lithium-powered batteries, in the harsh conditions of the use of a portion of the battery easier to induce deviations occur, giving rise to security issues.

2.2 Battery Management System (BMS) the important role of

Li-ion power batteries ideal for high performance, consistency, as long as the use of the process of filling, however, although put, there is no security issue,IBM 92P1060 Battery but the reality is that the quality of mobile phone battery factory in full compliance with standards, but in use there is an explosion incidents, notebook computer battery pack are also continuing fire, explosions, and product recalls reported. From the resulting life of the battery until the end of recovery, there are security issues, even in the factory in full compliance with international safety standards, in the course of evolution from the safe state to a state of insecurity and good quality single cell performance to achieve the life of a gradual decline limit , the poor quality of the single cell, in the course of its performance will start to appear and a variety of abnormal deterioration recession, worried about the insecurity of the state to enter. This is a gradual process of cumulative change. Battery management system is that unlike some battery manufacturers as a luxury but a must have, but also applied consistently throughout the battery pack. Battery management system at home and abroad have been many studies and start applications in many areas have been able to meet the needs of some markets, lithium power battery applications for battery management system put forward higher requirements to ensure the safe use of battery power, lithium power battery management system for the primary task.

3 Battery Management System

A typical battery charge PA3166U-1BRS battery  PA3176U-1BAS battery balance management system, its methods of work is to connect a good series battery charging at the same time, testing each single battery in the battery terminal voltage, when a single battery terminal voltage is high, The single cells in parallel with the balance of the circuit to the battery charge diversion, reduce the single battery charge speed and terminal voltage rise rate, so that the single battery terminal voltage tends to a balanced line, thereby to avoid the series battery each single battery charge and discharge characteristics of the differences affect the battery life. As the shunt charging the battery in parallel with the monomer part of the charging energy consumption of a balanced circuit, a balanced circuit fever, a balanced circuit balanced ability to be limited. For large-capacity, high-power battery, high current charge, the balance of the balance of the circuit capacity can not meet the actual needs.

According to authoritative statistics, as the pace car to enter the family continues to accelerate, Hp laptop battery as at the end of 2006, China's various types of privately owned vehicles for the first time more than 20 million, China has become the world's second largest after the U.S. automotive market. The industry believes that China's auto market has great potential, especially the private car consumption, in the next 20 years will continue rapid growth. However, especially in the automotive after-market automobile electrical storage Normal 0 7.8 磅 0 2 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} acer laptop battery dell laptop battery
Pool market, China and the United States, Japan and other foreign markets, compared to far worse, premature battery consumption, the whole concept of hindered development of the industry.
In this regard a survey data can illustrate the problem.

 

"Do you know the need for regular replacement of batteries it?", "Do you know your car battery to support the effectiveness of it?", "Do you know use environmentally-friendly and highly efficient battery product?" When asked about this series of problems, be able to answer up the car users are not many. Recently, a battery for the consumer knowledge about the extent of the survey results show that the owners of the investigation, the right car battery maintenance, repair knowledge, and develop a better understanding of the concept of active consumption, the owner of only about 17%. The car battery use, maintenance and maintenance of a lack of knowledge to create a typical "Chinese car users", an absolute majority of the owners do not understand the importance of automotive batteries for the vehicle, usually a good little concerned about the battery knowledge, the maintenance of batteries and maintenance is non-existent.

1 Introduction

Current power lithium battery power supply system development The main question is: power battery into a group of security and life after the significant decline, and even frequent battery fire, explosions and other serious accidents. Laptop Battery The main reason contributing to this problem is the power lithium battery group technology, group study of applied technology and equipment, lagging; to achieve power lithium battery system integration, to provide users with power lithium battery system integration technology and products to solve the current problem and promote the development of lithium battery power important subject.

At present, the single power lithium battery has been basically have the popularization and application of conditions, but the existing group technology, group applied technology and equipment levels are not yet ripe. In other words, single power lithium battery basically solved the safety and life issues, and promote the development of lithium battery power, the key is the battery technology, group technology and BMS.

Determine the quality of single cells into a group of post-power battery quality. In the power battery applications, the single cell performance consistency is especially important, given the present level of single cell manufacturing process control, through the battery produced in accordance with its actual performance to filter, group, assembly is a realistic way. At present, the application of industrial production screening, grouping method is based on the battery post into a few static parameters, with the battery group, with set of parameters that control standard determines the distribution group completed the battery when the battery status of each single line sex. In the battery pack in use, the battery group differences in each single state of the battery will gradually appearing. IBM ThinkPad R51 Battery Battery Management System (BMS) of the battery pack using process management, battery status of each single cell to adjust to a certain extent, you can maintain the battery status of each single cell consistency to avoid differences in the battery status of caused by the accelerated deterioration of battery performance. The development needs of battery-powered lithium battery raising the level of production process control, scientific group of the battery selection and distribution methods and effective battery management system and jointly promote.

 

In a private vehicle owners more than a random interviews, many have had problems because the car battery out of the anchor halfway experience. The owners for the understanding of automotive batteries still in the cortex, only know that car battery is used to start the car. Almost all of the owners Toshiba Satellite P30 battery interviewed asked, "After the car breaks down it aware of why, how to deal with", the answer surprisingly similar: "It might be a problem with battery or asphalt, usually called the 4S shop to trailers and to do repairs. "What are the reasons for the specific battery is a problem, almost no one can answer up. For how long the need for battery maintenance issues such as how long it needs to be replaced, they have never considered.

One engaged in auto repair 10 years of industry source said: "As China's car consumption started late, HP Pavilion dv9000 Battery(hp dv9000 battery), HP EV087AA Battery, HP EX942AA Battery but the speed on the market in supporting the post-state is still out of line, so that led to the car users are not aware of batteries for cars the importance of people's general view is that automotive batteries are non-wearing parts, HP Pavilion dv9000 Battery(hp dv9000 battery), generally only when able to be modified. consumers are in a passive consumption of state, very few people to replace yourself, or maintenance of batteries, they have to go 4S shop or repair shop to replace. "He also said:" Even though there is a small number of people concerned about the batteries, but also because of the price and choose a number of low-cost battery brand. "
