国外电动车用锂离子蓄电池研制概况

介绍了世界上主要电池公司的电动车和混合电动车用锂离子蓄电池研究进展和性能水平以及锂离子蓄电池电动车的情况。目前,研制的锂离子蓄电池单元和电池组已达到和超过USABC的中期目标(价格除外),几辆用锂离子蓄电池的电动车已成功地进行了证实性试验。但是电动车和混合电动车用锂离子蓄电池要推广应用还有一些问题,锂离子蓄电池性能还需进一步提高。

Development of foreign lithium-ion batteries for electric vehicle

The developmentand performancelevel of Lithium-ionbatter ies for EV and HEVmadeby major companiesin the world,and EVor HEVpoweredwith Lithium-ionbat-ter ies were introduced.Now,the performanceof developed Lithium-ionbattery module and pack have reached and exceeded the mid-termtarget of USABC(except for cost)and several electric vehicles with Lithium-ionbatteries have been tested for demonstra-tion successfully.But there are some problems to extend application of Lithium-ion batter ies for EVand HEV.The performanceof Lithium-ionbatteries for EVand HEVhas to be further improved.
