The invention relates to the technical field of power batteries, in particular to a charging method and device of a power battery, a vehicle and a storage medium, and the method comprises the steps that the current state of charge SOC and the charging temperature of the power battery are acquired; the current SOC and the charging temperature are input into a pre-established comprehensive satisfaction degree model, the optimal comprehensive satisfaction degree of the charging time and capacity fading of the power battery is output, and the comprehensive satisfaction degree model is a comprehensive satisfaction degree function established based on a charging time satisfaction degree function and a capacity fading satisfaction degree function; and charging the power battery according to the charging current corresponding to the optimal comprehensive satisfaction degree. Therefore, the problem that the service life of the battery is shortened due to the fact that the charging current is not sufficiently considered when the power battery is charged in the prior art is solved.

    本申请涉及动力电池技术领域,特别涉及一种动力电池的充电方法、装置、车辆及存储介质,其中,方法包括:获取动力电池的当前荷电状态SOC和充电温度;将当前SOC和充电温度输入预先建立的综合满意度模型,输出动力电池的充电时间与容量衰减的最优综合满意度,其中,综合满意度模型为基于充电时间满意度函数和容量衰减满意度函数建立的综合满意度函数;根据最优综合满意度对应的充电电流对动力电池进行充电。由此,解决了相关技术中在动力电池充电时,对于充电电流的大小考虑不足,从而降低电池的使用寿命等问题。
