摘　　要：电池的热管理可以保证电池在一个合适的温度区间内放电,且减少电池间的不一致性,提高电池的放电率和使用寿命。以10 Ah薄片型电池为基础建立电池组,设计上下两侧进出气的风道模型。与传统的风冷模型相比,该模型能够改善电池热管理效果,通过仿真分析表明,电池在2 C放电,电池组的温度差控制在2℃以内。The thermal management of the battery can ensure that the battery discharges in a suitable temperature range,reduce the inconsistency between cells and improve the battery discharge rate and service life.Using 10 Ah thin batteries as the research object,the model of the air inlet and outlet on both sides was designed.Compared with the traditional air cooling model,the model can effectively improve the efficiency of the battery thermal management.The simulation analysis show that the battery temperature difference is controlled within 2℃during discharging at 2 C.
