The invention discloses a battery pack low-temperature charging heating control method and device and related equipment. The method comprises the following steps: monitoring the working state of the battery pack, and when the working state is a gun insertion state, obtaining the current lowest temperature of the battery pack; determining a charging mode of the battery pack according to the current lowest temperature; when it is determined that the charging mode is a pure charging mode and it is determined that the environment temperature of the battery pack is smaller than a first temperature threshold value, refrigeration is controlled to be started or stopped according to the current state and the current highest temperature of the battery pack. According to the method, the charging time is shortened, and the thermal management energy consumption is reduced.

    本发明公开了一种电池包低温充电加热控制方法、装置及相关设备。该方法包括监测电池包的工作状态,当工作状态为插枪状态时,获取电池包的当前最低温度;根据当前最低温度确定电池包的充电模式;确定充电模式为纯充电模式,且确定电池包的环境温度小于第一温度阈值时,根据电流状态和电池包的当前最高温度,控制制冷开启或关闭。该方法缩短了充电时间,且减少热管理能耗。
