The invention relates to the technical field of vehicle thermal management control, and discloses a thermal management control method, device and equipment of a power battery and a storage medium, and the method comprises the following steps: in the charging process of the power battery, obtaining parameter information, a heat increment and a heat exchange speed of the power battery; calculating the temperature rise speed of the power battery based on the parameter information, the heat increment and the heat exchange speed of the power battery; and controlling the power battery to heat or stop heating according to the temperature rise speed. According to the technical scheme, the problem that when the vehicle is slowly charged at low temperature, the charging pile has charging output, but the SOC of the power battery of the vehicle does not rise or even declines, so that electric quantity loss is caused in the charging process of the vehicle is solved, the charging efficiency of the vehicle is improved, and the charging time of the vehicle is shortened.

    本申请涉及车辆热管理控制技术领域,公开了一种动力电池的热管理控制方法、装置、设备及存储介质,该方法包括:在动力电池充电过程中,获取动力电池的参数信息、热量增加值和热交换速度;基于动力电池的参数信息、热量增加值和热交换速度计算动力电池的温升速度;根据温升速度控制动力电池加热或者停止加热。应用本申请的技术方案,解决了车辆在低温慢充时,存在充电桩有充电输出,但车辆动力电池的SOC没有上升,甚至还会下降,导致车辆充电过程中电量损耗的问题,提升了车辆的充电效率,缩短了车辆的充电时间。
