摘要
锂离子电池作为电动汽车的主要储能动力源,是影响电动汽车动力性和经济性的主要因素。锂离子动力电池系统的SoC使用范围的设计是动力电池系统设计的难点,目前尚无统一认识。为了更好地利用电池,本文从功率需求、容量需求、效率、寿命等角度对锂离子电池系统SoC使用范围进行了综合分析。
Li-ion battery as the power source of electric vehicle/hybrid electric vehicle is the main factor for motility and economy.The design of the using range of SoC is the key point of battery system,there is noconsensus about it to date.In order to make a better use of battery,the SoC usage range of Li-ion battery system was analyzed from the impacts of power demands,capacity demands,efficiency,life.
