摘要
通过理论分析,建立了串并联混合电动汽车(HEV)运行的功率分配模型,由此确立了HEV设计参数与动力电池设计参数间的关系.研究了HEV所用电池的容量、组合数及放电倍率与HEV的相关设计参数间的匹配关系.从理论上解释了HEV所用动力电池的基本特性.计算对比了HEV在高速公路、市区内正常行驶及超低速行驶3个运行过程中的功率分配情况,表明在高速公路加速时HEV对动力电池的要求最高.以镍氢电池为说明对象,研究了电池容量、电池组合数及充放电倍率之间相互关系.
Theoretical analysis of correlativity between power batteries and HEV have been carried out with a model of power distribution which is established for series parallel HEV. Study on relationship between power batteries and HEV shows that characteristic parameters of batteries such as capacity, series numbers and charge/discharge rates, are strongly affected by HEV parameters. Theoretically, the basic characteristics of power batteries are interpreted.
