新能源车电池低温用电机加热研究及验证

Research and Verification of Motor Heating for New Energy Vehicle Batteries at Low Temperature

本文通过设计一种电机堵转给电池加热的方案,在电池低温环境中电机产热给电池加热,让电池温度快速上升,保证电池的充放电性能,节省充电时间,降低加热系统成本。

In this paper,a scheme of motor plugging to battery heating is designed.When the battery is in a low temperature state,the motor produces heat to heat the battery,so that the battery temperature rises rapidly,which ensures the charge and discharge performance of the battery,saves charging time and reduces the cost of heating system.
