The invention relates to the technical field of battery heating, in particular to a battery heating control method and system, a medium and a vehicle. The method comprises the following steps: collecting the current temperature and the residual electric quantity of a power battery, determining the available electric quantity of the power battery according to the current temperature and the residual electric quantity, obtaining the target discharge power of the power battery according to the current temperature and the residual electric quantity, and obtaining the required electric quantity and the required power of a vehicle in a preset travel; and performing heating control on the power battery according to the required electric quantity, the required power, the available electric quantity and the target discharge power. In the application, whether to heat the power battery or not is judged according to the required electric quantity and the required power of the vehicle, and if the required electric quantity and the required power can meet the navigation planning path, the power battery does not need to be actively heated, so that extra power consumption caused by heating of the power battery is avoided, and the endurance mileage is improved.
本发明涉及电池加热技术领域,尤其涉及一种电池加热控制方法、系统、介质及车辆。采集动力电池的当前温度与剩余电量,根据当前温度与剩余电量,确定动力电池的可使用电量,根据当前温度与剩余电量,得到动力电池的目标放电功率,获取车辆在预设行程下的需求电量和需求功率,根据需求电量、需求功率、可使用电量与目标放电功率,对动力电池进行加热控制。本申请中,根据车辆的需求电量和需求功率,判断是否对动力电池进行加热,若需求电量和需求功率可以满足导航规划的路径,则不需要对动力电池进行主动加热,避免了动力电池加热带来的额外电耗,提高了续航里程。
