The invention belongs to the technical field of electric vehicles, and discloses an electric vehicle battery pack heating control method, device and equipment and a storage medium. The method comprises the following steps: when a vehicle meets a preset driving condition, acquiring a mileage signal and the lowest temperature of a battery pack; determining a real-time mileage value and an initial mileage value according to the mileage signal; determining a mileage difference value according to the real-time mileage value and the initial mileage value; when the mileage difference value and the lowest temperature of the battery pack meet a battery pack heating condition, starting battery pack heating; and collecting and updating the lowest temperature of the battery pack, and stopping heating the battery pack when the updated lowest temperature of the battery pack meets a heating stop condition. By means of the mode, energy consumption is distributed more reasonably, short-distance driving energy consumption in the low-temperature environment is improved and reduced, and the low-temperature driving mileage of the pure electric vehicle is increased.

    本发明属于电动汽车技术领域,公开了一种电动汽车电池包加热控制方法、装置、设备及存储介质。该方法包括:在车辆满足预设行驶条件时,获取行驶里程信号和电池包最低温度;根据所述行驶里程信号确定实时里程值和初始里程值;根据所述实时里程值和所述初始里程值确定里程差值;当所述里程差值和所述电池包最低温度满足电池包加热条件时,打开电池包加热;采集并更新电池包最低温度,当所述更新后的电池包最低温度满足加热停止条件时,关闭电池包加热。通过上述方式,更加合理的分配能耗,提高减少低温环境下短途行车能耗,提升纯电动汽车的低温可行驶里程。
