The invention provides a charging control method for a power battery, electronic equipment and a storage medium, and the method comprises the steps: judging whether a vehicle has an external power supply request under the condition of detecting that the power battery of the vehicle meets a charging cut-off condition, and if yes, switching a charging loop of the power battery into an external power supply state, the main positive relay of the power battery in the charging loop is switched off, and then all electric energy output by external power supply equipment is provided for a high-voltage system which is running on the vehicle and comprises a thermal management device and other high-voltage accessories through the charging loop in the external power supply state, so that under the condition that the power battery meets the charging cut-off condition, the power battery is charged. According to the method, the external power supply equipment only supplies power to the running high-voltage system of the vehicle, the problem that the SOC is continuously reduced due to running of the high-voltage system can be solved, the situation that the power battery is repeatedly charged in a small range of the high SOC to cause an overcharge risk or influence on the service life can be avoided, and the method does not need to limit user function use scenes.

    本申请提供一种动力电池的充电控制方法、电子设备及存储介质,该方法在检测到车辆的动力电池满足充电截止条件的情况下,判断车辆是否存在外部供电请求,若是,则将动力电池的充电回路切换为外部供电状态,以断开充电回路中动力电池的主正继电器,进而通过处于外部供电状态的充电回路,将外部供电设备输出的全部电能提供给车辆正在运行的包括热管理器件和其它高压附件的高压系统,以实现在动力电池满足充电截止条件的情况下,通过外部供电设备仅为车辆正在运行的高压系统供电,既可以解决高压系统运行导致SOC持续下降的问题,也可以避免动力电池在高SOC的小范围往复充电所导致过充风险或对寿命产生影响,并且,该方法无需限制用户功能使用场景。
