Battery and its management system

1. Line of battery technology

Battery power system for electric vehicle battery to provide energy, including lithium ion batteries, nickel metal hydride batteries and lead acid batteries.

(1) different cell types of technical line

a. Lead-acid battery as safety, low cost, type in the micro-electric hybrid city car that has certain advantages. However, the low energy density, can not be applied on other types of electric vehicles.

b. Ni-MH battery technology is mature, safe sex, and in recent years to occupy the mainstream hybrid, especially in the light mixing, the mixture re-mix and other models. However, the low energy density, high cost, technological development has reached the limit, there is little room to further improve performance dell Studio 14 battery dell Studio 1435 battery .

c. excellent performance lithium-ion batteries, widely used, has a good prospect, will gradually occupy the mainstream of the future market position. However, safety and cost issues, a few days ago is still in development stage.

(2) line of lithium-ion battery technology

Lithium-ion battery cathode materials include lithium manganese oxide, lithium iron phosphate ternary materials and so on.

a. lithium manganese oxide and good safety, low cost, but poor high temperature performance, lower life.

b. Three high energy density materials, a more balanced performance, but the high cost.

c. the best safety of lithium iron phosphate, long cycle life, but poor low temperature characteristics, low energy density.

Most of the current battery of foreign companies such as Panasonic, Sanyo, SBL, LG, JCS, etc., the main choice of lithium manganese oxide and ternary materials; domestic enterprises and the United States most cell A123, the main choice of lithium iron phosphate. The near term, and ternary lithium manganese oxide material is more mature and will be the first industrialization. In the long run, lithium iron phosphate may gradually occupy the mainstream of the future market position.

2. Overseas development

(1) The main material of foreign enterprises with advanced technology, with related patents, a larger production scale, materials prices higher. Canada Phostech lithium iron phosphate has the original patent, the product sells for around 300,000 ~ 400,000 yuan / ton dell Studio 1436 battery .

(2) foreign key technical level of advanced battery companies, especially power battery better consistency, long life, can meet the vehicle requirements, but the cost is high. Sales have more than 2 million of the Toyota prius used nickel metal hydride battery, 8-year warranty in Europe, in the United States 10 years warranty, the battery costs about 15 to 21 yuan / Wh.

(3) foreign auto giants and professional auto parts companies have chosen to partner with professional battery, batteries using the battery business professional manufacturing capabilities, combined with their own vehicle or parts of electrical control design and system integration capabilities, to develop battery system. Such as Toyota and Matsushita formed PEVE company, Bosch and Samsung form SBL, Nissan and NEC form AESC companies, JCI and SAFT form JCS companies, this trend is particularly worth our attention.

(4) The Government attaches importance to power batteries and related materials, research and development, and actively invested heavily subsidized business development. The United States invested 2.4 billion U.S. dollars in 2009 to support the electric car R & D and industrialization, mainly related to power batteries, materials and systems. Japan plans from 2007 onwards, 5 years, 24.5 billion yen investment for R & D vehicle battery dell Studio 15 battery dell Studio 1535 battery .

(5) Foreign companies invested heavily to expand production capacity battery. Japanese companies such as the AESC plans to invest 100 billion yen, Sanyo plans to invest 80 billion yen; U.S. companies, such as JCS plans to invest 220 million U.S. dollars, A123 plans to invest 600 million U.S. dollars to expand production scale lithium-ion battery.

(6) foreign-related institutions and companies have launched the next generation of new power battery development projects. Japan in 2007 launched “the development of new generation cars and fuels program,” the aim of 2030, will be the quality of battery energy density has increased to 7 times the cost reduction to the current 1 / 40.

3. Present Situation in China

(1) Power Battery Materials

a. battery of major raw materials in China is rich in resources, industrial development and secure.

The main raw material resources, including battery lithium, graphite, rare earth, lead, these resources are abundant mineral resources in China are among the world’s top three, as the driving force of the battery industry to provide effective protection.

b. lithium-ion battery anode material has the localized product performance at the international advanced level.

Anode materials in China mainly include natural graphite, artificial graphite and mesophase carbon microbeads MCMB, the product basically covering the domestic market, some products have been sold into the global top three.

c. lithium iron phosphate material many manufacturing enterprises, to meet the less battery power.

More than a hundred domestic enterprises to manufacture lithium iron phosphate material, but only a few manufacturers of products can basically meet the vehicle power battery requirements, and product stability issues have not yet fully resolved.

d. lithium ion battery separator material samples have been developed, performance should be improved.

Internal membrane products in the traditional lithium-ion battery market has been partially replace imported products, but all imported power battery separator, battery separator is still domestic sample stage of development dell Studio 1536 battery .

(2) battery

a. lithium-ion battery has formed products, mainly 1 ~ 50Ah products, some manufacturers have developed more than 50Ah products, like cars and to support demonstration models supporting, but not the formation of industrial production capacity. Ni-MH battery also has developed products, mainly for the 6 ~ 100Ah products, some products can complete production models.

b. internal lithium-ion battery companies have made some progress in skills, in particular progress in security index significantly. But the business skill levels, poor product consistency, overall and there is a certain gap between the international advanced level, and the gap continues to expand.

In the after-sales service, most domestic manufacturers of lithium-ion battery provides only 1 year warranty period, individual manufacturers can provide 3-year warranty period, while some foreign manufacturers of lithium-ion battery can provide 10-year warranty. In product prices, domestic products have advantages, Ni-MH battery costs about 10 yuan / Wh about the cost of lithium-ion battery is about 2.5 to 5 yuan / Wh.

c. domestic battery group technology has fallen behind, a big difference from the industrialization.

Group of individual manufacturers in the battery technology has a certain basis, initially approved vehicle business. But with the international advanced level, in the thermal management, balance, space utilization, etc. there are still a wide gap.

d. domestic enterprises planning to expand investment in the industrialization of active preparation.

In recent years, the battery business of the dramatic increase in industrial investment, such as ATL, power of God, BAK, Universal are planning more than one billion yuan of investment to expand capacity lithium-ion battery. Hunan Shenzhou, Hunan Branch Pa, the torch Schonlein also plan more than 500 million yuan of investment to expand capacity Ni-MH battery. However, most manufacturers still focus on the development in the early input of traditional batteries dell Studio 1537 battery dell Studio 1555 battery .

(3) Battery Management System

a. After “15″ and “Eleventh Five-Year” study, in the battery management system in China has made some progress, a more complete product features, to support the demonstration model matching, but not yet reached the level of industrialization.

b. the battery and vehicle industry are the lack of battery management system design and production experience, both the lack of close cooperation. Domestic battery enterprises generally commissioned a professional electronic company or the Higher Xiangguanjitong, Dan right battery internal law of Bugou depth Quefashuoju accumulation, Wu Fa extensive communication and design firm, affect product Xingneng.

c. The products feature simple, who are of the basic inspection and monitoring functions, but the reliability of data collection, SOC estimation accuracy, thermal management, balance, security management, and a wide gap between foreign countries.

d. non-vehicle electronic components and more level, and because of smaller volume, multi-use hand-welding the way manufacturing, product poor electromagnetic compatibility, stability, and low reliability.

(4) status of battery recycling and treatment

a. power batteries containing lead, strong corrosion solution will effect the environment pollution and waste battery must be the same income. And the battery in the lead, nickel, rare earth, lithium and other metals and other materials with the recovery value, battery recycling is conducive to recycling of resources.

b. United States, Europe, Japan and other developed countries have a complete recycling system. Has formulated special rules and regulations, and established a professional, size of the battery recycling company. China has not established a sound system and system recovery, some recycling companies pay no attention to environmental protection, causing secondary pollution.

c. As the vehicle requirements of high power batteries, some battery powered vehicles, although not able to, but the remaining capacity can meet the requirements of a number of energy storage devices, so use with cascade mode, to expand the use of part of the battery, reduce the cost dell Studio 17 battery dell Studio 1735 battery .

4. My power battery management system and its main problems

(1) lithium iron phosphate material as process control difficulties, poor stability batches, the battery manufacturing process control difficulties, resulting in low power core product, resulting in higher manufacturing costs of batteries. And materials, the original patent on the core issues, can not avoid facing greater risks.

(2) battery with the former divide are imported, domestic battery separator is still in the sample stage, it is difficult to replace imported products in the short term.

(3), lithium iron phosphate membrane and key production equipment imported.

(4) single sample battery cycle life can reach a high level, but because of poor product consistency, power core group, the system’s cycle life is reduced.

(5) in the battery management system, the lack of familiar with batteries and battery management system, complex professional; product system features simple, there is a big gap between performance and abroad; product engineering design capability is weak, poor reliability dell Studio 1737 battery .

In the thin film solar cell technology in this emerging field, a number of Chinese companies far behind. However, this green energy technologies also face environmental challenges and the need to address market barriers

Status of Chinese solar energy industry a bit like a piece of South Africa’s World Cup side of the billboard: “British interests in China,” the emergence brings is hope for the future. But a billboard of “flash” and not overnight, put into a strong brand overall.

In fact, “broke into the World Cup,” the British interest groups is a member of China’s solar energy industry.

At present, the solar cell is divided into: crystalline silicon solar cells (including monocrystalline silicon, polycrystalline silicon), amorphous silicon solar cells (the thin film solar cells), and multi-compound solar cells. In the three solar cells, the first two more common now, and diverse compounds for industrial production of solar cells as yet, so the market rarely get dell Inspiron 1501  dell Inspiron 1525 battery .

As the name suggests is the layer of thin film battery into the solar cell thin films, due to its silicon is extremely rare and therefore easier to reduce costs. At the same time, both as a highly efficient energy products, but also a new type of building material, more easily combine with the building. In the international market continued shortage of silicon raw materials, the context of thin film solar PV market development has become the new international trends and hot spots.

“Film” Rise

In the thin film solar cell technology, a leader in the United States, Japan and other countries business. However, some Chinese solar energy enterprises in this emerging area not far behind.

“This is mainly because of the low-cost thin film solar induced.” Solar energy industry, one analyst told the “China News Weekly”, the biggest advantage of thin film solar cells is that you can not use expensive silicon, less than the required materials polycrystalline silicon solar cells, energy consumption was significantly lower than silicon solar cells. Of course, the thin film solar energy and higher technical difficulty, is considered the next generation after the polycrystalline silicon solar cells solar energy technology.

Currently, more types of thin film solar cells, has been large-scale industrial production are mainly three kinds: silicon thin film solar cells, CIGS thin film solar cells (CIGS) and cadmium telluride thin film solar cells (CdTe). The latter technology is the world’s largest manufacturer of thin film solar cells the first U.S. solar energy (First Solar) the monopoly, the photoelectric conversion rate of 11% to 12% or more. CIGS thin film solar cell technology is not yet widely used, the conversion rate of 10%. China’s new development in recent years, more than for the silicon thin film solar cell technology. According to experts, China Electronics Materials Industry Association, Li Qing Yan introduced, although the industrial scale thin film solar cells with crystalline silicon cells currently there are still large compared to the gap, but it is increasingly accepted by the industry, thin film solar cell industry has developed rapidly in recent years dell Inspiron 1526 battery  dell Inspiron 1720 battery .

China’s large-scale production of thin film solar cells started in 2008. At that time, the high price of crystalline silicon, resulting in investors turning to the relatively low cost thin film solar cells in the field. Yingli Energy (Beijing) Co., Ltd. However, Chen Ling, Project Manager explained that, due to thin film coatings using crystalline silicon only, so the use of fewer raw materials, raw materials cost much cheaper than crystalline silicon cells.

“At that time, the price of crystalline silicon cells up to more than three U.S. dollars per watt, thin film battery is just over one U.S. dollar per watt. And low cost also mask many shortcomings.” The analyst told, “China News Weekly.”

The risk of nitrogen trifluoride

Thin film solar cell industry in order to beat the competition in the future polysilicon cell, the first one to face the environmental challenges – thin film released during the production of nitrogen trifluoride, is considered a greenhouse gas.

In 2008, the University of California, Irvine, professor of Earth System Science Maikeerpu Strasser (Michael Prather) and his colleagues in the “Journal of Geography of the Earth,” published research papers, said nitrogen trifluoride to the greenhouse effect is carbon dioxide 17000 times. In the semiconductor, LCD panels and thin film solar cell production process may release nitrogen trifluoride.

Prather told the “China News Weekly,” nitrogen trifluoride significant greenhouse effect can exist in the atmosphere 550 years of very strong infrared absorption ability.

University of California, Scripps Institution of Oceanography Director Leiwei Si (Ray Weiss), who also found that nitrogen trifluoride concentration in the atmosphere in 1978 0.02ppt up to 2008 0.454ppt. Weiss said that while the current generated by human activities, greenhouse gases, carbon dioxide accounts for 60%, only 0.04% of nitrogen trifluoride, but the proportion of nitrogen trifluoride may grow exponentially. He told the “China News Weekly”, “Our monitoring results show that the atmospheric emissions of nitrogen trifluoride higher than the expected 4 to 5 times.” dell Inspiron 1520 battery dell Inspiron 1521 battery  

At present, the “Kyoto Protocol” involves six kinds of gases: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. Prather and Weiss suggested that nitrogen trifluoride is also included in the required reduction of greenhouse gases out. On the other hand, Weiss also pointed out that emissions of nitrogen trifluoride proportion of very low, it is not the worst greenhouse gases. Moreover, most of the use of clean energy technologies, both thin film solar cells or wind turbines, the production of greenhouse gases will be accompanied by the emergence of life, but as long as they offset the greenhouse gas emissions, then these new technologies is still useful of.

For example, he said: “The thin film solar panels and more number of years of life, and they just need a year or two can make up for production of greenhouse gases released.”

“Intruders” needs to prove himself

Li Qing Yan told the “China News Weekly”, “At present, thin film solar cell solar cell industry in China, the proportion of only about 10%. Moreover, in the next 10 to 20 years within the industry it also does not dominate. ”

At present, the commercialization of thin film solar cell technology of the three, the silicon thin film technology is the most easy promotion; cadmium telluride technology as cadmium, heavy metals, so there is a potential risk of environmental pollution; the CIGS technology is due to the need use of indium, gallium, selenium three elements are rare earth elements, its production is limited, large-scale commercial point of view on the existence of certain obstacles. Silicon thin film technology, silicon is generally required, the company usually gets the technology and production lines, with the possibility of large-scale commercialization.

However, according to Chen Ling introduced, although the thin film solar cells look very cheap, but it is not the case. First of all, with the photoelectric conversion rate as high as 16%? 17% in terms of the crystalline silicon solar cells, thin film Dianchi’s conversion rate low, the battery current domestic Sheng Chan Neng reach about 8% 就 quite satisfactory; second, Youyu right thin film solar technology there are some doubts, so demand for thin film solar cells is still small, for export-oriented solar cell industry, even in China’s thin film solar cell production Jiaoda 商 it in Europe Meiyou any visibility. Furthermore, the production line more expensive, plus the smaller domestic producers in each production line depreciation costs. “These factors shared equally told, thin film solar cell production cost is not cheap.” Ran Chen Ling said.

It is understood that the existing 30 in China about thin film solar manufacturing enterprises, most of which use the European production line for production. Meanwhile, China’s major solar markets abroad. Foreign buyers to banks for loans, banks are most concerned about the credibility of solar cell manufacturers, so many buyers in the choice of producers when the multi-enterprise credit investigation as the main factor.

“Buyers have difficulty applying for bank loans, as produced in China thin film solar cells has not been a 10 or 20 years of the verification process, so banks do not trust you.” The solar industry analyst told reporters.

Chinese products in international market because few people used the lack of “birthright”, which is the thin film solar cell industry is facing problems. This may be the 80-year history in the World Cup, the first time the reason for China’s sponsors – the United Kingdom interest “into the World Cup,” the move, let people on the solar energy industry “in China,” added the prospect of hope dell INSPIRON 2600 SERIES  dell INSPIRON 2650 SERIES .

Manufacturing process from the beginning until all the applications, low-power technology has become indispensable for all design needs. Energy-sensitive applications, especially single cell must provide the product for several hours operating time, more needs to join the ultra-low power design concepts. To meet these requirements, we must integrate the microcontroller, which features not only to understand the battery, Huan requires a thorough understanding in order to achieve continuous use of 10,15 or even 20 but Wu Xu Nian Dian Chi’s target change, how should Sheji a Zhuang Zhi.

To operate at very low power conditions, it must look to new ways of looking at these very low power applications. Traditionally, these complex applications are in a more convenient point of view to analyze their power consumption, for example of the application and use of power to a hypothesis in order to generate “typical” power consumption Apple MacBook Pro 17 inch battery  Apple PowerBook G4 12 inch battery .

However, for example, to achieve continuous operation of 20 years of single-battery-powered applications, applications must learn self-discharge rate than the lower battery power, which makes every nA of power in the overall power budget in the more crucial.

Industry standard CR2032 button cell battery self-discharge current is less than 250nA. Is a common CR2032 lithium / manganese dioxide battery, nominal (no load) voltage of 3.0V. In practice, to achieve the longest battery life, you must use a highly integrated microcontroller (MCU). In sleep mode, the MCU must be able to within less than 1μA good in operation, while providing the right mix of processing power, and integration of external and on-chip memory.

When each nA of power are critical, the only assumption on the performance or power to do the method is no longer absolutely feasible. In order to assess the best choice of design, the need to examine more parameters, although in some less sensitive to energy applications, these parameters did not seem critical. For instance, for advanced ultra-low-power sleep mode the microcontroller is already very common, however, micro-controller for the whole family will sleep mode power consumption the same approach may be not quite correct. Well-known microcontroller product line can show more than 1,700% change. Therefore, for ultra-low power design, focusing on the choice of microcontrollers to the performance without sacrificing low power conditions to upgrade the memory, and the pin must be compatible.

Another focus is to assess, over time, equipment, battery changes. All the engineers are aware, a battery voltage over time is largely determined by the structure of the battery and load. To CR2032, for example, a pair of AA / AAA alkaline battery it will have a different discharge patterns, result, a well-designed for Yingyong, the battery must be in a variety of qualifications, can Xiangtong performance Yunzuo Apple PowerBook G4 15 inch battery  Apple PowerBook G4 17-inch battery . To not consider the battery characteristics, on the terms of an engineering team to Zai one pair of power-sensitive applications using the same series of microcontrollers Kong Zhiqi products but also to pledge products with a single Dianchigongdian Weichiduonian normal operation is quite not easy. Consider the design team focus on low-voltage power characteristics, and operational performance. At this point, the microcontroller can operate at 2V or lower applied voltage, in order to gain more battery power. In addition, low voltage conditions, the micro-controller high-frequency operation must be maintained to ensure maximum application performance.

With low-power design needs of stable growth, the effective instruction set architecture (ISA) growing importance. On energy-sensitive applications are likely to have 99% of the time in sleep Moshi next, inevitably, these devices to Ding Qi, or use predefined times in intervals, or be awakened by Waibuciji Er. In this regard, in order to achieve the task, designed to consider the key lies in the total energy usage. Design team must select ISA allows the microcontroller, these components have a higher percentage of single-cycle instructions to perform specific tasks, which can short implementation time and lower power consumption to complete the task.

For example, the use of a generic C function memcpy () from a memory address of 32 bytes of data copied to another location, and for the PIC24F and MSP430 compiler, then the resulting code requires more than a 790 MSP430 % duty cycle (316vs.40). 4MHz at 3V and conditions, this example MSP430 consumes more energy than a 230% higher. This shows the importance of ISA.

In the construction of future applications, the embedded electronics industry has reached a watershed, the current design of integrated components, assessment and practice methods will be undergoing changes. Special significance of this shift, the next few years, more applications will integrate in its low-power design techniques Apple MacBook 13 inch unibody battery  Apple MacBook 15 inch unibody battery .

The size, title, Fujian Fuzhou people, former Professor of Chemistry, Xiamen University, retirement came to power ultra-Wei Co., Ltd., in technical management.

From 1958, Chen began to study cell body of titles is the battery in China earlier research, teaching and the combination of electrochemical production experts. He engaged in electrochemical research, teaching more than 50 years, of painstaking research in the field, and the development of China’s battery industry and made great contributions to advances.

In 2004, nearly 70 old ultra-Wei Chen body corporate title was recruited, participate in the company’s guidance for each new product development work, he specialized in battery knowledge and experience in the field of ultra-prestige group of experts on the issue in depth of thought helpful His opinions are subject to each senior and expert attention.

Chao Wei company started in 2008, solar lighting project. Solar lighting is a method of renewable energy, solar lighting, but a market price of a few thousand dollars or so often, the average per unit cost of 20 yuan, and each had to replace the battery two or three years, this “noble product” solar lights hindered the process of industrialization and marketization. Thus, Chen body determined by extending the title to reduce the cost of solar battery life, Wei He led the research and development experts over the subject is captured with a gel electrolyte replacement solution in general, all of a sudden will prolong the lifespan of solar cells to 7 years. “If the solar cell 7 years in accordance with the cost of life told, with solar lighting and electricity prices are about the same.” The size, title, said, less to the laying of cables, power facilities, increase the complexity of the hardware, the same price of solar energy lighting will soon be promoted IBM ThinkPad T41 battery  IBM ThinkPad T42 Series battery .

Last year, Chao Wei and Xiamen, a company signed a “long-life photovoltaic cell R & D base settled in Xiamen,” the agreement, and now, more than 90 light solar lights have been installed in the United States and Britain Village, Xiamen set. “I realized solar lights ‘common people’, the group has a growing number of localities and enterprises try to use solar lighting up.” Chen told reporters title body, the national advocacy in the current context of energy saving and emission reduction, green, renewable the use of solar lighting systems will be very bright future.

Repeated several times to recharge the battery, charging time can go far, this is electric vehicle battery technology core. Recently, the author, Dalang Town, McNair Technology Co., Ltd. (hereinafter referred to McNair) was informed that the company successfully developed the “long life” battery started small batch production, which marks the company to enter the electric car battery industry, a key step step.

To successfully enter the field of electric vehicles, McNair go yes Chan Xueyan line, with 712 research institutes, Dongguan, Shanghai University, Institute for Nanotechnology in-depth cooperation, respectively Yanfa electric vehicle battery safety technology, the battery using nano materials, key technologies, work the removal of the domestic battery industry “Crown” Pearl.

Mao Tiejun said McNair in 2006, electric car battery research and development for the province of Guangdong and Hong Kong in 2007 and was tender project, started 8-10Ah battery of structural design, preparation and mass production such as research and development. “As of 2009, the company and its key materials, battery electric vehicle research and development costs on the accumulated investment of 12 million yuan.” Mao Tiejun said Apple A1148 battery  Apple A1175 battery .

Currently, electric vehicle batteries and the development of key materials, the McNair for invention and utility model patents, over 10, 10, a number of provincial and municipal projects in 2004 in 22 countries and regions registered the “McNair” trademark.

“Li-ion battery industry and the smart grid and other new energy and new energy vehicles these two closely related strategies, emerging industries, the Chinese government will speed up the introduction of development planning and policy support rules, and encourage private enterprise to play high-tech R & D innovation-based force. In addition, from the fiscal and credit support such as, in particular credit policy to favor small and medium enterprises. “China’s State Information Center, Fan Jianping, chief economist at the July 29 ~ 30, held in Shenzhen,” 2010 lithium ion battery international forum for new materials “, from the macro-policy, described the development direction of China’s lithium battery industry.

Government to promote lithium battery industries, will focus on three aspects concerns Wen Ti: 1, Track Kuaguogongsi latest trends, choosing the right, there are hopes Chengweiweilai main direction of the Jishu and organized Jinhanglianhe research. Second, the technical standards as soon as possible to solve practical problems in China, the formation of joint research and share results of uniform standards for creating basic conditions for industrial applications. Third, establish high standards of intellectual property protection system in China sony VGP-BPS12 battery  sony VGP-BPS13 battery .

The third point above, the issue of intellectual property protection to attend the forum attracted a strong response from professionals. Taiwan Kai Li Chih-Wei Yang energy technology with the “patent: the disappearance of a Chinese puzzle” to describe his situation on the Chinese market concerns about the current patent. He said that, in fact, the intellectual property rights, the Chinese battery industry has long been hindered face of patents and technological monopoly of commercial interference.

For example, as early as 2000, China Ni-MH Ovonic Battery Company, once by the United States in patent infringement allegations. Including BYD, Lucky, three general in Shenyang, Shenzhen, South China Sea and three-chun, Sony 8 to Ovonic Battery Company of China paid a huge amount of royalties.

July 2003, Sony made lithium batteries in Beijing BYD patent litigation. Currently, BYD events a year for legal expenses related to approximately 100 million.

July 2008, 3M on the Sony, Sony Electronics, Lenovo, Lenovo U.S., Hitachi, Panasonic and other 11 companies carried out the technical aspects of patent prosecution battery.

Therefore, China’s relevant departments and enterprises should manage the battery patent Fangmian greater attention, especially the Dianchi export of enterprises, As much as possible Zhangwo Zhishichanquan respect legal knowledge, to protect their own interests, Yi Mian Fei’s been a huge Zhuanlishouquan injury sony VGP-BPS13/S battery  sony VGP-BPS13A/B battery .

On the other hand, as of July 29, 2010, the Chinese patent on the lithium iron phosphate are 201, including materials composed of 24 patents, materials, technology patents and 177. From 2003 to 2010, Chinese enterprises in this area the number of patent applications has been rising. However, since 2005, final approval and the actual number ratio of the number of applications instead of showing a continuous downward trend.

In response to these circumstances, Chih-Wei Yang pointed out that enterprises should pay attention to the blindness of the patent application, because the number of patents and do not represent the true strength of a business. Patent application must focus on practical products, novelty and creativity.

Lithium iron phosphate material in the field of control of a key U.S. patents. University of Texas with NTT of Japan as lithium iron phosphate material litigation over patent issues, the result will be owned by NTT was forced to lithium iron phosphate material patents licensed to the University of Texas, to the other party paid 30 million U.S. dollars of the settlement. After, many Taiwanese companies have battery lithium iron phosphate by purchasing patents to avoid such disputes. Suzhou Heng is chairman of the board, according to Science and Technology, Hangzhou Sainz Dr. Dong Ming, president of energy technology introduction, in fact, Japanese companies such as Matsushita and Toyota also has a lithium iron phosphate material of similar patents, but because NTT events, these enterprises those who did not practice with the lithium iron phosphate material, and the main preference and ternary materials, lithium manganese oxide. Although Japan and Taiwan in the lithium iron phosphate material patents at a disadvantage, but in Europe the situation is completely different. December 2009, the European patent award for the revocation of the University of Texas of the lithium iron phosphate of the European patent, to protect the future development of European business interests iron phosphate lithium battery technology sony VGP-BPS13A/S battery  sony VGP-BPS13AS battery .

September 2009, the Chinese Ministry of Science and the “863 Program” has been clear that the lithium iron phosphate cathode material support for key technology development, the Chinese research institutions and companies are actively developing. According to Dong Ming, Heng is the electrochemical activity of materials science and technology manufacturing method patent (patent number: CN200910186259.9) was in 2010 in the U.S., Japan, Korea and other 16 countries or regions worldwide for granted.

In addition, the Chinese patent ruling in Europe’s ability to withdraw the United States as China’s iron phosphate lithium battery patent license, will largely determine the lithium iron phosphate, and materials of Chinese company Jin Hou’s Fa Zhan. However, Chih-Wei Yang said that even so, the future export of products for the North American business, trouble not been eliminated. However, in a certain period, the European market, the industry will provide some opportunities.

Furthermore, Chinese enterprises lithium manganese oxide, ternary materials, the future may also occur patent dispute with Japanese and Korean companies to do this early to prepare sony VGP-BPS13B/B battery .

Recently, the work led by the Ministry drafted a letter, “New Energy Auto Industry Development Plan” (hereinafter “Plan”) content exposure, the program is the first of a new energy industry-specific sector development plan that will guide the next 10 years China the development of new energy automotive industry.

The exposure of the “new energy automotive industry development plan” put forward in 2020, the scale of China’s new energy auto sales to be up first in the world; new energy to electric cars to the main technical line; the next 10 years and financial investment 100 billion yuan to create new energy vehicles industrial chain.

A source close to government departments, industry experts said that this plan has now been completed on the business of consultation with industry experts, is currently being sought the views of relevant ministries. Subsequently, the Ministry of Industry and will be formally submitted for approval to the State Council. Goes well, planning is expected to formally introduced during the year VGP-BSP13/S  GP-BPS10 .

Objective world

An enterprise by a foreign car, government and environmental agencies and many other forces are expected to contribute to the electric car craze in China, staged climactic scene. Because this year is expected to formally introduce the “new energy automotive industry development plan to” lock the 10 years the world’s development goals.

“Plan” put forward by 2020, new energy automotive industry and market size to reach the world’s first. Among them, the new energy vehicles (plug-in hybrid vehicles, electric cars, hydrogen fuel cell vehicles, etc.) to maintain capacity to 5 million; to hybrid vehicles as the representative of the fuel-efficient vehicles sold in the world, annual sales reached 1,500 10000.

“Planning” has developed to achieve this objective two-step strategy. From 2011 to 2015, power battery, motor, electronic control and other key components of the core technology to achieve independence, pure electric vehicles and plug-in hybrid electric vehicle initial industrialization, the market volume of more than 500,000 reserves; the other to achieve general large-scale hybrid vehicles industrial, moderate, severe hybrid car ownership scheme more than one million; basic mastery of advanced internal combustion engines, automatic transmissions, VGP-BPS10A  VGP-BPS10B automotive electronics, light weight and other key technologies, the average passenger car fuel consumption of 5.9 liters / 100 km.

From 2016 to 2020, electric cars and plug-in hybrid vehicles to achieve industrialization, market ownership in hope more than 5 million; massive popularity of hybrid vehicles, moderate, severe hybrid vehicle sales of more than 300 annual 10000; also advanced internal combustion engines, automatic transmissions, automotive electronics, lightweight, large-scale popularization of key technologies, passenger car average fuel consumption of 4.5 liters / 100 km.

This is undoubtedly a series of ambitious goals, achieve them is not easy. Consider the automobile industry development policy before the fall of the lesson the number of Mubiaojingchang, the industry experts close to the government said the number of objectives other than static, emphasis Biaoming new energy vehicles in China reached the forefront of the industrialization of the determination. If the new energy automotive technology advances quickly, to promote the successful demonstration of these goals in the future the process is likely to further increase. If not successful, have reduced the number of targets possible VGP-BPS9A/B  VGP-BPS9/S .

And last year introduced the top ten industrial restructuring and revitalization plan as the first new energy industry for the industrial development policy, not by several ministries jointly issued a departmental rules, but by the State Council issued the country’s highest administrative organ. Its importance is evident.

Taking a battery-based

Not long ago, Secretary, Ministry of Industry and Zhang Xiang Mu equipment industry have said the formulation through planning, and actively guide full of local and corporate social investment role, to avoid low-level, blind investment and duplicated construction phenomenon.

“Plan” put forward, will adhere to the pure electric as the transformation of China’s automobile industry the main strategic orientation. Focus on the development of pure electric vehicles, plug-in hybrid vehicles, focusing on the traditional automotive technology level, to develop energy efficient cars, and keep track of fuel cell vehicle technology, local conditions, appropriate development of alternative fuel vehicles sony VGP-BPS13AS battery  sony VGP-BPS13B/B battery .

In order to avoid indiscriminate investments, low-level redundant construction, “planning” make build “national team”: combination of demonstration projects to create new energy automotive industry pilot demonstration base; rely on existing car key enterprises in the construction of Changchun, Shanghai, Wuhan, Chongqing, , Beijing, Guangdong, Anhui and other energy-saving and new energy vehicle industrial base. By 2020, the base of industrial concentration above 90%, 2-3 home nurture the formation of more than 6 million sales of large-scale automobile enterprise group, 1-2 production and marketing of new energy scale of more than 1 million vehicles in the auto groups 3-5-scale production and marketing of new energy vehicles to 500,000 vehicles enterprise groups.

It is noteworthy that “planning” is also proposed to establish and improve standards of small low-speed electric vehicle laws and regulations. This means that those who were not regular car-industry enterprise business team, the capital also has the opportunity to enter the field of electric vehicles.

“Planning” also reflects the emphasis the development of new energy vehicles to build public R & D platform, the concept of the industrial chain. Plan proposes to rely on national research institutes and research university, building a number of national saving and new energy vehicles and parts of test base, the establishment of industry-wide sharing of test platform and product development data.

Crucial in the development of battery electric vehicles, we should set up a national power in the world advanced level cell research. Key construction in Tianjin, Shenzhen, Hangzhou and other lithium-ion battery industry gathering area. 2-3 scale production and marketing training home more than 20 billion watts, with cell materials R & D and production capacity battery leading enterprises were formed 2-3 lithium-ion power key enterprises at home Sony battery .

In order to avoid the car in the field of key technologies of the old road hollow, “planning” provisions of the new vehicle power batteries, drive motor, vehicle control system, a key component of new energy vehicles joint venture enterprises with independent research capabilities and needs of intellectual property rights, the Chinese stock ratio not less than 51%.

100 billion government investment

To achieve the new energy scale in the world auto industry’s goals, “planning” that the Government has taken special fund central subsidies, tax relief and other measures, from the development, production, marketing and other aspects multi-pronged approach.

“Planning” proposal in 2011 to 2020 decade, the central government invested 100 billion yuan heavily. Of which, 500 billion for energy-saving and new energy auto industry development of special funds to support R & D and industrialization of key technologies, and promote joint development of mechanisms of public platforms; 30 billion yuan to support the demonstration and popularization of new energy vehicles; 20 billion yuan for promotion of hybrid vehicles focus on fuel-efficient vehicles; another 100 billion yuan was used to support the core automotive components industry; 5 billion yuan for the pilot urban infrastructure projects VGP-BPS2C  VGP-BPS5 .

“Planning,” also suggested that the next 10 years, the Government tax policy to promote energy conservation and new energy to great benefits vehicle. For example, exemption from pure electric vehicles, plug-in hybrid car vehicle purchase tax, halved ordinary hybrid car vehicle purchase tax and consumption tax. Included in the “national priority areas to support high-tech” enterprises and key parts of the vehicle business, the high-tech enterprises will enjoy the state income tax incentives.

Smart Battery System (SBS) the emergence of the independent battery systems greatly simplify the design, so its application has been Chao Chu of the notebook computer field, and reappear in other various applications Biru backup Dianyuan system, high-reliability military and aerospace applications. Other key applications include the automotive, security / surveillance / security systems, medical equipment, blade servers, telecommunications and portable electronics.

Smart battery using the internal electronic circuits to measure, calculate and store the battery data, it makes use of a more predictable power supply. Moreover, another important advantage of smart battery that can prevent unexpected system downtime XPS M1730 battery XPS M2010 battery .

A basic SBS system consists of the following components: System Management Bus (SMBus), intelligent battery charger and smart battery.

SBS’s modular design features closed-loop battery charging system to become very easy, such a system allows for independent battery charger (smart charger), minimizing the non-duplication of hardware and software engineering (NRE) of the cost of and contributed to a solid system, which high reliability is particularly important application of battery backup. The integrated battery pack in the highly accurate barometer is able to accurately monitor the battery has been, even when the battery is not in the same system. The pressure gauge in accordance with the actual battery capacity values of the calibration, thus removing the bias, ensuring accuracy.

Smart battery charger main function is to provide smart battery charging voltage and current sources. Smart battery charger through the SMBus interface and smart communication and can choose to communicate with the host. In order to prevent the loss of function and overcharge SMBus, watchdog timer and running to monitor smart battery and charger call frequency. If the battery is no movement for more than 3 minutes, then pause and wait for the battery charger to charge the request again. In addition, the battery can also force the shutdown function to control the charger, so you can bypass the SMBus, to provide redundancy level and let the battery charger that is real Inspiron XPS M170 battery Inspiron XPS M1710 battery .

Compared with the fixed independent chargers, smart battery charger has the following advantages.

① truly plug and play, free from battery chemistry and battery configuration effects. Intelligent battery pack can be any smart battery charger with any. With different chemical characteristics, configuration, and even different battery charging algorithm can be used without modification for the charger circuit.

② built-in security features. SBS standards watchdog timer and a battery and charger in particular between the “safety signal” interface.

③ reliable battery detection system.

④ automatic charge management, not the host.

⑤ without host intervention in closed-loop charging system. Host can power measurement information to be collected.

LTC1760 Dual Smart Battery System Manager XPS M140 battery XPS M1530 battery  

LTC1760 is a highly integrated battery charger and selector 3, for the use of dual smart battery products. It is a buck topology switching battery charger with intelligent battery standards meet the definition of a variety of functions and other new features, such as input current limiting and security restrictions, and so on. 3 SMBus interface allows the LTC1760 to achieve, such as track two battery’s internal voltage and current of the type of servo functions, and allows a SMBus host monitors the status of any battery. This servo technology allows the battery charger with the accuracy of the internal voltage and current measurement error of only ± 0.2%.

Traditionally, dual battery system is the order of discharge system, allowing battery power consumption in order to simply extend the overall battery life. LTC1760 uses a proprietary analog control technology that allows security to parallel the two batteries to charge or discharge. This structure to charge a 50% speed, battery life extended by 10%. In addition, the parallel discharge not only enhances the current capabilities, but also reduce the I2R loss and improved conditions at very high load capacity of the voltage regulator. Lower I2R losses and improving the voltage regulation were extended timing solutions, the total discharge time.

The main features ● LTC1760 XPS M1210 battery XPS M1330 battery  

① independent three polling battery charger charging requirements and monitoring by the internal battery power measurements to determine the actual current and voltage (error ± 0.2%), fast, secure and completely charge.

② fast charge mode can be used to further shorten the charging time.

③ support the battery checked to achieve the barometer calibration.

④ 3 power supplies allow safe access FET diodes and low-loss and two from the DCIN the same time discharge the battery.

⑤ two FET diodes to achieve two batteries at the same time safe, low loss to discharge.

⑥ hardware programmable current and voltage security constraints, and many other security features to supplement the battery’s internal protection circuitry.

LTC1760 Although very precise, but very easy to use. In any given design only identified four key parameters: input current limiting resistor RICL, and matching the current limiting resistor RILIM charge current detection resistor RSENSE, limited pressure resistance RVLIM, short circuit protection resistor RSC.

LTC1760 plus some smart battery and an AC adapter, you can form a simple system.

● Input current limiting resistor RCL Inspiron XPS Gen 2 battery

Shown in Figure 2, this circuit limits the charge current to prevent the system from the AC adapter when the power increase of overload. To set the input current limit, the most important thing is to minimize the wall fitting device rated current. Limiting resistor can be calculated under two formulas.

“BYD is a satellite unit last year, we have to find the next BYD.” Hong Kong, China Everbright Holdings analyst Li Weimin told reporters that the new energy vehicles have been in the Mainland and Hong Kong is the most popular areas of common interest investors.

Just which part or sub-sectors with higher barriers and prospects, which may be part of a great company compaq Tablet PC TC1000 battery ?

“I think the investment in new energy vehicles are subject to all the best varieties, and other problems facing the industry is the story finished, the profit can not be honored.” Shanghai, a new energy to the field says.

Auto industry in the country’s new energy policy is increasingly clear, investors are most concerned about several issues: First, how much profit can be available immediately.

Problem 2: In the industry chain is, whether the selected upstream raw material suppliers, or select the middle or lower reaches of the vehicle battery manufacturers. Which part of most interest to investors involved in it?

“We think the battery and motor areas of investment opportunities than the material in 2010 -2 012 years, motor and control system of market capacity will be 130 billion yuan, the battery in the field of market capacity at 190 million, while the materials market capacity, but 30 billion. “Yuan Yao analysts believe compaq Tablet PC TC1100 battery  compaq Presario 1700 battery .

“Motive power industry from scratch, market capacity from the current ten million to about 32.5 billion yuan in 2012, a huge room for growth enables companies to have reason to enjoy the high valuation.” SW analyst Wang Hua also that link is the biggest benefit from the battery part.

From the industry perspective, the material in the field of traditional industries from the path not far away, not entirely new industry, and the battery, the electrical power source for vehicles, but the technology is still exploring. And downstream of the vehicle plant, due to the water currently in the testing phase, hybrid, electric vehicles subject to high costs and lower sales of relying on government procurement, subsidies, can not generate profits in the short term is an inevitable.

“Of course, if from the risks that the upper and middle reaches of the battery material differences also came out, middle battery technology companies to bear more risk alternative materials relatively small area, such as CITIC Guoan, after the battery if this material was not his , he would not suffer significant risk. But the huge amounts of money into the battery manufacturers do not. for instance, are two lines of nickel hydrogen, lithium batteries, we recognized the advantages of lithium batteries should be higher. adhere to the listing of nickel hydrogen line company’s ability to grow on the questionable, such as Section power far. “Shanghai, a public offering of investment fund managers talk about their ideas compaq Presario 2100 battery .

Electrical field is now generally optimistic for the agency is oceanic motor, which is already the ocean Foton, Dalian bus, Suzhou Jinlong, Shenzhen Wuzhou Dragon and other new energy vehicles the main motor and control system supplier. Reported according to the NDRC urban planning, 2012, these four cities together to promote new energy bus 14000. It is estimated that in Beijing alone this year will have nearly a thousand electric vehicles, sanitation vehicles and 500 buses on the road over the new energy, so the ocean will realize annual sales income of new energy vehicles about 150 million yuan, net profit of 030 million -0.4 million contribution . In the beginning of the development of new energy vehicles, Ocean Motor profit pocket already.

1 June, the state issued a “personal car allowance to buy new energy policy.” Has already arrived in August, the “energy saving and new energy vehicle development plan” will be submitted to State Council for approval. Gradually introduced a series of policies have delivered a clear signal: China’s new energy vehicles will be a clear line of development, full development of new energy automobiles and related industries to meet the new energy automotive revolution in the global auto industry.

We are generally talking about the new energy vehicles, is three kinds of solutions, collectively, that is, hybrid vehicles, electric cars and represented by hydrogen fuel cell vehicles. To our neighbors South Korea, for example, investment in development of the three at the same time. Such as Hyundai and Kia cars, hybrid, the 2009 introduction of the Elantra [Review Photo Forum] Hybrid, Geneva Motor Show in March this year to launch a diesel hybrid i-flow, 10 月 will also introduce Sonata hybrid. Electric vehicles, next year in August to test operation of modern Kia mini electric cars, and production part. The modern electric vehicle charging seven hours using lithium-ion batteries VGP-BPS8 , VGP-BPS8A , will reach 130 kilometers per hour. Fuel cell, Hyundai Kia Motors to complete the world’s most advanced fuel cell system. Hydrogen fuel cell powered Hyundai Tucson [Review Photo Forum], Kia Sportage [Review Photo Forum] a day without interruption across from San Francisco to Los Angeles 635 km, and now is trying to run 4 cars.

In fact, the cost of electricity supply, China has the development of electric vehicles the advantages of new energy resources. To successfully develop the world’s first lithium-polymer battery Elantra LPI Hybrid Hyundai Kia Motors, for example, Hyundai and Kia vehicles in the world now maintain two Blue Drive with the Eco Driving green brand, also plans to 2013 , Hyundai Kia Motors will be in the green car R & D spend 4.1 trillion won.

On new energy development plan in China, Hyundai Kia relevant responsible person said that the “first quarter to 4.6 million this year to continue to lead the world auto market, China has huge purchasing power and economic development momentum, the future development of new energy potential of non-auto market underestimated. I believe in planning the development of five pilot cities practice a mature business model, China will usher in new energy vehicles in short supply in the future. Hyundai-Kia Motors is also actively preparing for, willing to fully support the development of new energy vehicles in China VGP-BPS13B/B , VGP-BSP13/S . “
