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.

At present, the Institute in cooperation with relevant universities and companies have together to build a Chinese high-power lithium-ion battery system development platform
