The invention provides a power battery power correction method, a vehicle and a storage medium. The method comprises the following steps: acquiring initial discharge power of a power battery; obtaining a minimum single battery voltage and a minimum single battery temperature in the power battery, and determining a single battery target power based on the minimum single battery voltage and the minimum single battery temperature; and correcting the initial discharge power based on the target power of the single battery to obtain the final discharge power of the power battery. According to the application, the voltage closed-loop control correction is introduced according to the minimum single battery voltage and the minimum single battery temperature in the power battery, so that the correction of the initial discharge power of the power battery is realized, and the risks of over-high power output and over-discharge of the battery when the single battery voltage value of the power battery is too low are avoided.

    本申请提供一种动力电池功率修正方法、车辆及存储介质。该方法包括:获取动力电池的初始放电功率;获取动力电池中的最小单体电池电压和最小单体电池温度,并基于最小单体电池电压和最小单体电池温度,确定单体电池目标功率;基于单体电池目标功率对初始放电功率进行修正,得到动力电池的最终放电功率。本申请以动力电池中的最小单体电池电压和最小单体电池温度,引入电压闭环控制修正,以实现对动力电池的初始放电功率的修正,避免在动力电池的单体电池电压值过低时,产生功率输出过大,电池过放的风险。
