The invention discloses a charging pile preheating method, device and equipment and a storage medium, and relates to the technical field of electric vehicle charging, and the method comprises the steps: obtaining the temperature of a battery pack in response to a charging signal of a charging pile; performing voltage control on the voltage converter based on the battery pack temperature; when the voltage of the voltage converter is equal to the voltage value of the battery pack, the heating unit is controlled to preheat the battery pack, the battery pack can be preheated without high voltage under the condition that the battery pack is extremely low in temperature, and the charging mode can be switched when the temperature of the battery pack is appropriate.

    本申请公开了一种充电桩预热方法、装置、设备及存储介质,涉及电动汽车充电技术领域,包括:响应充电桩充电信号,获取电池包温度;基于电池包温度对电压转换器进行电压控制;当电压转换器的电压等于电池包的电压值时,控制加热单元对电池包进行预热,可以在电池包极低温情况下无需上高压即可完成对电池包预加热,在电池包温度合适同时可切换成充电模式。
