The invention discloses a battery thermal management control method, a battery management system and an electric vehicle. The method comprises the steps that a vehicle BMS sends temperature data and duration data to a cloud BMS; the vehicle BMS receives the current optimal working temperature of the battery and the current target dormancy duration returned from the cloud BMS; the vehicle BMS determines a difference value obtained by subtracting a preset minimum SOC value from the current SOC value of the battery; and the vehicle BMS controls the working temperature of the battery according to the difference value, the current optimal working temperature of the battery and the current target dormancy duration, the battery is heated or cooled through self-awakening of the vehicle BMS, the battery reaches the optimal working temperature in advance, the waiting time of a user can be shortened, heat management in the whole life cycle of the battery is achieved, and the service life of the battery is prolonged.
本发明公开了一种电池热管理控制方法、电池管理系统和电动车辆,该方法包括:车辆BMS将温度数据和时长数据发送到云端BMS;车辆BMS接收从云端BMS返回的当前电池最优工作温度和当前目标休眠时长;车辆BMS确定电池的当前SOC值减去预设最低SOC值的差值;车辆BMS根据差值、当前电池最优工作温度和当前目标休眠时长控制电池的工作温度,通过车辆BMS自唤醒进行加热或冷却电池,使电池提前达到最优工作温度,可减少用户等待时间,并实现在电池的全生命周期进行热管理,提高了电池的使用寿命。
