纯电动汽车动力电池热管理技术探析

Analysis on Thermal Management Technology of Power Battery of BEV

纯电动汽车动力电池在充电放电时会产生大量的热量,在经过低温静置后,温度会很低,此时动力电池需要热管理系统为其冷却或加热,以保证续驶里程、使用寿命和安全性。文章总结了动力电池冷却和加热的不同方式,列举某款纯电动汽车热管理系统方案,为电动汽车热管理系统设计提供参考。

The power battery of BEV will generate a lot of heat when charging and discharging,and after low temperature resting,the temperature will be very low,by now the power battery needs a thermal management system to cool or heat it to ensure driving range,service life and safety.This paper summarizes the different ways of power battery cooling and heating,and lists a BEV thermal management system scheme,which provides a reference for the design of BEV thermal management system.
