The invention relates to a power battery power control method and device, a vehicle and a storage medium. The method comprises the steps that actual state information of a power battery in a preset working time period is obtained; determining the working voltage of the power battery according to the actual state information; according to a preset current threshold value and the working voltage of the power battery, the working power of the power battery is determined, the working power is the product of the working voltage and the preset current threshold value, the preset current threshold value is the allowable maximum current when the power battery is in the working state, and the working power is the power when the power battery is in the working state; when the working power is greater than the preset power, determining the preset power as the allowable power of the power battery; when the working power is smaller than the preset power, determining that the working power is allowable power of the power battery; wherein the preset power is the power of the preset working time period to which the actual state information belongs, and the service life and the safety of the power battery are ensured.

    本公开涉及一种动力电池功率控制方法、装置、车辆和存储介质,包括:获取动力电池在预设工作时间段的实际状态信息;根据实际状态信息确定动力电池的工作电压;根据动力电池的预设电流阈值和工作电压,确定动力电池的工作功率,工作功率为工作电压与预设电流阈值的乘积,预设电流阈值为动力电池处于工作状态时允许的最大电流,工作功率为动力电池处于工作状态时的功率;当工作功率大于预设功率,确定预设功率为动力电池的许用功率;当工作功率小于预设功率,确定工作功率为动力电池的许用功率;其中,预设功率为实际状态信息所属的预设工作时间段的功率,保证动力电池的使用寿命以及安全性。
