The invention provides a thermal management method for a vehicle-mounted battery. The thermal management method comprises the steps that the vehicle state, the pre-driving distance, the predicted vehicle using duration, the real-time temperature of the vehicle-mounted battery and the to-be-started duration are obtained; estimating the estimated energy consumption, ideal energy consumption and battery heating energy consumption of the automobile running for the preset running distance at the real-time temperature and the preheating time required for heating the vehicle-mounted battery from the real-time temperature to the ideal temperature according to the estimated vehicle using time; judging a vehicle state; when the preheating function of the vehicle is in an on state and the state of the vehicle is flameout, controlling to preheat the vehicle-mounted battery according to the to-be-started duration, the preheating duration, the estimated energy consumption, the ideal energy consumption and the battery heating energy consumption; otherwise, the vehicle-mounted battery is not preheated. By means of the thermal management method and system of the vehicle-mounted battery, the service life of the vehicle-mounted battery can be prolonged.

    本发明提供了一种车载电池的热管理方法,包括:获取车辆状态、预行驶距离、预计用车时长、车载电池的实时温度和待启动时长;根据预计用车时长预估汽车在实时温度下行驶预行驶距离的预估能耗、理想能耗、电池加热能耗以及车载电池从实时温度加热至理想温度所需要的预加热时长;判断车辆状态;当车辆的预加热功能处于开启状态,且车辆状态为熄火时,根据待启动时长、预加热时长、预估能耗、理想能耗和电池加热能耗,控制预加热车载电池;否则,不对车载电池进行预加热。通过本发明提供的一种车载电池的热管理方法以及系统,能够提升车载电池的使用寿命。
