Thermal management

Thermal management controls the temperature of an EV battery, power electronics and other components so they operate within suitable limits. Systems can use liquid cooling, air cooling, refrigerant circuits, heaters or combinations of these approaches. Battery temperature affects available charging power, discharge power, ageing and safety protection. The BMS uses temperature information when setting allowable limits. Thermal management is therefore part of both driving and charging performance, particularly at high DC charging power.
