In the recently concluded 13th session of the Shanghai International Auto Show in a variety of stylish electric car concept has attracted the eyes of those who show. According to statistics, at this auto show, the brand new energy vehicles for the promotion of an unprecedented effort to increase, only a pure electric vehicles have as many as 14 models, in addition to foreign luxury brands, a joint venture brands, belonging to people's own proprietary brands, a strong realization of of the economic crisis of the "new battery energy" theme.

But back to reality, when it comes to the "mass production" this topic, it seems that very few car companies can stand out. Even if the battery is well-known BYD, it is not listed on its New F3DM as a production vehicle, only to the State government departments. Because, for China's industrialization and the development of electric vehicles, is still facing some difficulties need to be overcome.

The plight of a battery life well below the standard production

The new energy vehicles, according to experts in open-tong Wu, Senior Engineer, at present the electric vehicles have not yet reached volume production conditions, the toshiba laptop battery reason lies in the batteries for electric vehicles has not yet reached the reliability and life conditions for volume production. "While in Beijing during the Olympic Games, we used a number of vehicles, new energy vehicles, but in reality, these hybrids, there has also been poor battery reliability problems."

According to report, although China has a lot of battery production enterprises, the quality of the individual cells able to meet the standard, but once the battery tested together, they found that energy consumption is very large, the reliability can not guarantee and can not achieve the production standards. Therefore, how these monomers after the batteries up in series or in parallel to ensure its normal operation, a key issue. "In accordance with standard vehicle battery life for more than 5,000 hours to achieve, while the current battery life of electric vehicles can only be maintained at approximately 2000 hours, well below the toshiba pa3284u-1brs battery standard of life." Wu said open-tong.

Even in the United States and other developed countries electric vehicles, for the manufacture of battery levels are also there are many problems. It is open-tong Wu introduced last August, Toyota Prius had already used the well-known U.S. battery manufacturer's battery, on the highway due to a short circuit and cause spontaneous combustion.

The plight of two building blocks for charging facilities required to meet the national grid

For electric vehicles, the supporting toshiba pa3285u-1brs battery facilities is the key, that is, both the plug-in hybrids or pure electric cars, had to rely on city's fast-charging network. "To put a longer-term, the State is able to provide plug-in charging station, equipped with every family the possibility of charging the garage. These have a direct impact on the industrial development of electric vehicles." Open-tong, said Wu.

At present, throughout the country, electric cars are few fast-charging stations, which also contributed to BYD F3DM since late last year the retail market has not the direct cause. While BYD has been listed in the F3DM said that among the fast-charging stations are under construction, but did not give a specific timetable for the construction of charging stations. In addition, the issue of cooperation with the national power grid, nor any follow-up messages.

"To build an electric car charging stations, the toshiba pa3285u-2brs battery cost of investment is very significant. Only the construction of a charging station needs over 3,000 million yuan, while in a city would need at least several hundred charging stations to meet demand." Recreational-tong Wu frankly, in building the basis of charging facilities, there is no co-ordination of the national grid, almost no prospect of success. However, huge investment needs of national and regional government-funded, otherwise it will not be established.

"This will involve the upgrading of urban circuit, assembly, conversion devices, and even residents of meters may involve transformation is a very complex issue and the huge investment." Senior analyst, said the division bell.

The plight of three replacement batteries need Qiba Qian Yuan, consumers difficult to accept

Electric cars cost more than toshiba pa3285u-3brs battery conventional gasoline cars, electric cars are also difficult to mass commercial production, one of the main obstacles. It is understood that the domestic use of pure electric vehicles are mainly lead-acid batteries, nickel-metal hydride batteries and lithium-ion batteries, its costs are in a few thousand dollars to a few ten thousand dollars. According to the experiment showed that lead-acid rechargeable battery can only be repeated 300-500 times. Based on the current can travel 100 kilometers per charge calculation, a lead-acid battery can be driving 30000-50000 km. The current set of lead-acid battery electric car is probably Qiba Qian Yuan's selling price, if the electric car, after traveling 30,000 kilometers in need of replacement batteries, the cost is almost the same car with ordinary fuel. Moreover, the cost of replacement batteries to the present no specific figures. For consumers, vehicle price and the cost of vehicles is a measure of its electoral vehicle, an important indicator of car, if the car, car costs are rising, naturally unwilling to accept.

Local government first introduced the new energy vehicles competing subsidy policy


Driven by a strong central government,toshiba pa3331u-1brs battery, local governments started to become a vehicle to promote the development of new energy the mainstay of the country's 13 pilot cities to subsidize the promotion of policies have been introduced. In mid-April, Nissan and Engineering Department and the Wuhan municipal government letter signed two agreement, including a letter for the workers developed by the Department, including charging network construction and maintenance, the promotion of large-scale use of electric vehicles, while in 2011 the first to introduce electric cars in Wuhan . This is by far the workers a letter signed by the Ministry of multinational companies first electric vehicle development agreements.

Meanwhile, before the World Expo 2010, Shanghai plans to update the bus 4000. Among them, the country Ⅲ emission and environmental protection, public transportation vehicles, more than 50%. In addition, Shenzhen, Chongqing, Changchun, Dalian has also performed in this Shijizhizhan eye-catching. In December of this year, the NDRC will also take the lead in the development of new energy vehicles infrastructure planning,toshiba pa3356u-1brs battery,toshiba pa3356u-2brs battery,toshiba pa3356u-3brs battery most of which the content directly to electric cars.

According to the Investment Adviser Lee Sheng-mao auto industry analyst noted that with the gradual promotion of new energy vehicles, the future demand for power lithium battery materials will be detonated. Right now, although China electric bicycles, motorcycles and other light electric vehicles to retain volume has more than 50 million, ranking first in the world, thus derived are also a large number of battery manufacturers. However, some key technologies, it is still foreign to master, lithium batteries with the electrolyte membrane, is one example.

Lithium-ion batteries with a working voltage due to the high energy density (light weight), no memory effect, long cycle life, and pollution-free, etc., all kinds of electronic products to become the main power supply, the global demand for lithium-ion batteries average annual increase of 30 %, and a huge market, China's current lithium-ion battery production accounted for more than a third of the world's total and more than 100 manufacturers of lithium lithium-ion battery materials, the strong demand for lithium-ion battery from the positive and negative electrodes, electrolyte and polymer material isolation membrane composition, divide the Department of Li-ion materials technology, the highest barriers to a high-value-added material, gross profit margin is usually 70% or more, accounting for 20-30% of the cost of lithium ibm laptop battery. Isolating film lithium-ion battery commonly used polypropylene (PP), polyethylene (PE) single-layer microporous membrane, as well as PP and PE by the multi-layer composite microporous membranes as a separation membrane, polypropylene, for example, its raw material cost of about eight thousand dollars / ton, but will its processing into a membrane, its value can be up to 300 yuan / ton, a substantial appreciation of the several hundred times.

From the exterior point of view, it is an ordinary white plastic no significant difference, but in the structure of lithium batteries, the diaphragm is one of the key components of the inner layer. Membrane performance, a direct impact on the ibm thinkpad r50 battery capacity, cycle performance, and security features such as. Fosugufen Chief Engineer, Jin Hui, chairman WU Yao Kan pointed out that as a high technological content, divide the last localization of lithium battery products, and now has mastered the film's core technology. At present, the domestic annual demand is about 130 million square meters, while Jinhui company to 1,200 million square meters.

According to the Investment Advisor "issued by China's new energy vehicles 2008-2010 Industry Analysis and Investment Consulting Report" points out that by 2012, if the formation of one million hybrid vehicles the size of the battery separator need nearly 400 million square meters, while the current domestic divide the total production capacity is only 130 million square meters. Future power battery is likely to be double-type growth, their needs will be 10 times more cell phone battery.

Polymer film in the thin-film solar cells with a wide range of applications in the same space, development and production of lithium ibm thinkpad r50e battery separation film, solar photovoltaic system for the new material is a film company in the general direction of industrial upgrading. However, domestic enterprises can produce only a handful of membrane, leading to have been subject to foreign imports, high prices, it is lithium a major cause of high production costs, of course, affect the application of lithium, one of the important reasons.

At present, the domestic companies able to produce membrane only star-source technology, Jinhui High-Tech 2 technology is ibm thinkpad r50p battery relatively mature market, a serious shortage of supply, most dependent on imports, the market dominated by Japanese Asahi Chemical Industry, Tonen Chemical, and the United States Celgard dominate. Membrane with a typical "high-tech, high-capital" characteristics, and the project cycle is very long, the investment risk greater enthusiasm for investing in domestic enterprises is not high.

Expected global demand for polyethylene, polypropylene and aromatics and other major demand for petrochemical products will be higher than the global GDP2-3% rate of growth, while the fastest growth rate in Asia. To this end, the world's leading petroleum and petrochemical companies,ibm thinkpad r51 battery, ExxonMobil Chemical is actively investing in order to meet this growing demand. Through the ongoing construction of a joint venture in Fujian, China and the construction of new petrochemical plant in Singapore to make it a world-class petrochemical plant of the increase in production capacity more than doubled. Meanwhile, Saudi Arabia and Qatar is also to promote large-scale investment projects, and in Korea, the construction of a new lithium battery separator plant.

Although the development of lithium power industry divide on the promotion of great significance, but from investment point of view statement, diaphragm with a typical "high-tech, high-capital" characteristics, and the project from start to production operation cycle is very long, greater investment risk, to a certain extent hindered of domestic enterprises in this ibm thinkpad r52 battery important area of investment.

Lithium battery charging process is like this: First detection voltage voltage, if more than 2V, which shows that the battery performance of normal, began to constant current charging, the standard charging rate is 0.2C, which 860mAH battery will be close to 200mA of current charging, up to 4.2V, then go to constant voltage charging, that is, 4.2V constant voltage, current getting smaller and smaller, until the charge current is less than 0.01C, that is around 10mA, the charge for the full instructions, this time can stop charging, but also to continue to charge, but the power will not increase in number, in fact E398 charging rate is 0.4C, with each time the battery has not left empty, there are nearly 30% of the electricity, so when the time is normally filled only about three hours can be filled.


Cell phone lithium battery nominal voltage is 3.6V, after full voltage is 4.2V, in fact the standard rate of discharge (0.2C, C is the lithium battery capacity) lithium battery discharge platform, generally in the 3.7V, lithium battery pack in the In fact, also include a shield to protect board's main role is to prevent the lithium battery overcharge and over discharge and short-circuit, so although marked on the battery with metal objects that can not short-circuit the pavilion dv2000 battery , hp hstnn-lb31 positive and negative, but in fact you have nothing to do with short-circuit , the protection board will move to cut off discharge circuit.

Because the chemical properties of lithium batteries, if no post-discharge the battery may be damaged, so need to design protection circuitry to prevent battery over-discharge, the general design of the over-discharge protection voltage of 2.4 - 2.6V, while mobile phone applications, mobile phones house will also have power management circuitry in the mobile phone to detect when the battery is depleted and will show enough electricity to meet the voltage detection, battery has not been to release will be off automatically. Lithium battery charging voltage normally-off set at 4.35V, because the charging voltage value of the IC over shipments of the largest, in fact, if the hp f4486b ,hp cgr-b1870ae,pavilion zd7000 battery , pp2182d battery,hp laptop battery voltage charge to 4.35V is already a bit too filling, and is best 4.25V to stop charging.
