The invention relates to a power battery charging control method and device, equipment, a storage medium and a vehicle, and the method comprises the steps: obtaining a target SOC difference value which is used for indicating the difference between the SOC value of a battery cell with the maximum SOC value in a power battery in a full charge state and the SOC value of a battery cell with the minimum SOC value; based on the relation between the redundant charging SOC value and the battery cell SOC threshold value, the charging cut-off SOC value of the target power battery is determined, the redundant charging SOC value is the sum of the target SOC difference value and the basic charging SOC value, and the basic charging SOC value is the sum of the target SOC variable quantity and the discharging cut-off SOC value; the charging cut-off SOC value is larger than the basic charging SOC value and is smaller than or equal to the smaller one of the battery cell SOC threshold value and the redundant charging SOC value; and under the condition that the SOC value of the first battery cell in the target power battery is equal to the charging cut-off SOC value, stopping charging the target power battery.

    本申请涉及一种动力电池充电控制方法、装置、设备、存储介质和车辆,该方法包括:获取目标SOC差异值,目标SOC差异值用于指示满电状态下动力电池中SOC值最大的电芯的SOC值,与SOC值最小的电芯的SOC值之差;基于冗余充电SOC值与电芯SOC阈值的关系,确定目标动力电池的充电截止SOC值,冗余充电SOC值为目标SOC差异值和基础充电SOC值之和,基础充电SOC值为目标SOC变化量与放电截止SOC值之和;充电截止SOC值大于基础充电SOC值,且小于或等于电芯SOC阈值和冗余充电SOC值中的较小值;在目标动力电池中的第一电芯的SOC值等于充电截止SOC值的情况下,停止对目标动力电池进行充电。
