The invention provides a battery heating control method and device, a storage medium and a vehicle, and belongs to the technical field of vehicles. According to the embodiment of the invention, under the condition that the battery temperature of a high-voltage battery is smaller than or equal to a temperature threshold value, the output voltage of a charging pile is determined as first pile voltage based on the current battery voltage of the high-voltage battery; wherein the first pile voltage is smaller than the current battery voltage; and then the heating device is controlled to be started, the switch module is closed, and the first pile voltage is sent to the charging pile, so that the charging pile supplies power to the heating device according to the first pile voltage. According to the embodiment of the invention, the output voltage of the charging pile is limited to be smaller than the current battery voltage of the high-voltage battery, so that no current flows into the high-voltage battery in the process that the charging pile supplies power to the heating device. Thus, in the process of heating the high-voltage battery, the lithium precipitation phenomenon of the high-voltage battery can be effectively avoided, and the service life of the high-voltage battery is effectively prolonged.

    本申请提供了一种电池加热控制方法、装置、存储介质和车辆,属于车辆技术领域,本申请实施例在高压电池的电池温度小于或者等于温度阈值的情况下,基于高压电池的当前电池电压,确定充电桩的输出电压为第一桩电压;其中,第一桩电压小于当前电池电压;进而控制加热装置开启,开关模块闭合,并将第一桩电压发送给充电桩,以使充电桩按照第一桩电压给加热装置供电。本申请实施例通过限制充电桩的输出电压小于高压电池的当前电池电压,能够在充电桩给加热装置供电的过程中,确保不会有电流流进高压电池内。如此,能够在加热高压电池的过程中,有效避免高压电池出现析锂现象,进而有效提高高压电池的使用寿命。
