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使用范围进行综合分析。
The lithium-ion battery is the main factor to influence the dynamic property and economical efficiency of EV as its power source. The design of used range of battery SOC is the key point of battery system, and there is no consensus about it to date. In order to make a better use of battery system, the used range of battery SOC is analyzed from the aspects of power demand, capacity requirement, efficiency and life.
