The invention relates to the technical field of battery heating of new energy automobiles, in particular to a battery heating control method and system.The battery heating control method is characterized in that heating conditions are distinguished, and heating modes are divided into three heating modes including charging heating, idling heating and traveling heating according to different states of an automobile; the temperature thresholds for entering and exiting heating in the three heating modes are different, and the threshold temperature for starting heating and the threshold temperature for ending heating in the idling heating mode are both lower than the threshold temperature for starting heating and the threshold temperature for ending heating in the charging heating mode and the driving heating mode; therefore, the normal use of the vehicle in a driving or charging state can be ensured, the heating frequency of the vehicle in an idling state can be reduced, and the energy consumption is reduced.

    本发明涉及新能源汽车的电池加热技术领域,更具体地,涉及一种电池加热控制方法及系统,其中电池加热控制方法对加热工况进行了区分,针对车辆处于不同的状态,将加热模式分为充电加热、怠速加热、行车加热三种加热模式;所述三种加热模式进入和退出加热的温度阈值是不同的,其中怠速加热模式的开启加热的阈值温度和结束加热的阈值温度均低于充电加热模式及行车加热模式下开启加热的阈值温度和结束加热的阈值温度,从而既能确保车辆在行车或充电状态下的正常使用,又能减少车辆在怠速状态下的加热频次,减少能耗。
