The invention provides a battery electric quantity correction method and device, a vehicle and a computer readable storage medium, and relates to the technical field of vehicles, and the method comprises the steps: judging whether a power-off event of the vehicle is triggered or not when the correction condition of the remaining electric quantity of a battery pack is satisfied; if yes, executing depolarization operation of the battery pack; under the condition that depolarization of the battery pack is completed, obtaining a voltage extreme value in voltages of all single batteries of the battery pack; and correcting the remaining capacity of the battery pack according to the voltage extreme value. According to the invention, active correction of the SOC of the vehicle battery pack can be realized, and the accuracy of SOC estimation can be improved.

    本申请提供了一种电池电量修正方法、装置、车辆和计算机可读存储介质,涉及车辆技术领域,该方法包括:在满足电池包的剩余电量的修正条件时,判断车辆的下电事件是否被触发;若是,执行电池包的去极化操作;在电池包去极化完成的情况下,获取电池包的所有单体电池的电压中的电压极值;根据电压极值修正电池包的剩余电量。本申请能够实现车辆电池包的SOC的主动修正,有利于提高SOC估计的准确性。
