The invention provides a dynamic heating control method and device for low-temperature charging of a battery, electronic equipment and a storage medium, and the method comprises the steps: dynamically adjusting the lower limit and upper limit of a battery heating threshold value based on the current SOC of the battery; and dynamically adjusting the target water temperature based on the current total heat absorption amount of the battery. The target water temperature for heating can be dynamically adjusted, so that the temperature rise rate of the battery dynamically corresponds to the current total heat absorption capacity of the battery, and the situations that heating becomes slow and charging time becomes long due to the too small temperature rise rate and the temperature difference becomes large and the service life becomes short due to the too large temperature rise rate are avoided. And meanwhile, the heating threshold value of the battery is controlled to change in real time along with the charging process, so that the battery can enter or exit heating in time according to the corresponding heating threshold value in different charging stages, the battery is always maintained in the optimal charging temperature range, and both the charging time and the heating energy consumption are reduced.

    本申请提供一种电池低温充电的动态加热控制方法、装置、电子设备和存储介质,其中,电池低温充电的动态加热控制方法包括:基于电池的当前SOC动态调整电池加热阈值的下限和上限;基于电池的当前总吸热量动态调整目标水温。本申请能够动态调整用于加热的目标水温,使电池的温升速率与电池的当前总吸热量动态对应,避免温升速率过小导致的加热变慢、充电时间变长,以及温升速率过大导致的温差变大、使用寿命变短。同时,通过控制电池的加热阈值随充电过程实时变化,保证电池在不同的充电阶段都能根据对应的加热阈值,及时进入或退出加热,使电池始终维持在最佳充电温度范围内,兼顾减小充电时间和降低加热能耗。
