The invention relates to a battery power control method and device, a vehicle and a storage medium, and relates to the technical field of automobiles. The method is applied to a vehicle which is provided with a power battery, and comprises the following steps: acquiring the current voltage of the power battery; under the condition that a first difference value between the current voltage and a first preset voltage is smaller than a preset threshold value, the current power and a second difference value of the power battery are obtained; and performing interpolation processing on the first difference value and the second difference value to obtain a power change coefficient corresponding to each voltage in a plurality of voltages between the current voltage and the first preset voltage. And in the process of changing the current voltage of the power battery to the first preset voltage, adjusting the power of the power battery according to the power change coefficients corresponding to the plurality of voltages. Therefore, the technical problem that the accuracy of the output power of the power battery is low can be solved.

    本申请涉及一种电池功率控制方法、装置、车辆及存储介质,涉及汽车技术领域。应用于车辆,车辆设置有动力电池,该方法包括:获取动力电池的当前电压。在当前电压与第一预设电压之间的第一差值小于预设阈值的情况下,获取动力电池的当前功率和第二差值。对第一差值与第二差值进行插值处理,得到当前电压与第一预设电压之间多个电压中每个电压对应的功率变化系数。在动力电池从当前电压变化至第一预设电压的过程中,按照多个电压对应的功率变化系数,调整动力电池的功率。由此,可以解决动力电池输出功率的准确性较低的技术问题。
