The invention relates to a power battery temperature control method and device and a vehicle. The invention belongs to the field of battery temperature control. The method comprises the steps of: obtaining a plurality of battery cell temperatures of a power battery, and enabling each battery cell temperature value in the plurality of battery cell temperature values to correspond to a different battery cell area of the power battery and to be used for representing the current temperature of the different battery cell area; and under the conditions that the minimum battery cell temperature in the plurality of battery cell temperatures is greater than a preset first temperature threshold, the maximum battery cell temperature in the plurality of battery cell temperatures is less than a presetsecond temperature threshold, and the difference value between the minimum battery cell temperature and the maximum battery cell temperature is greater than a preset first temperature difference threshold, adjusting the temperature of the power battery in a constant temperature mode so as to reduce the difference between the temperature of a first battery cell area with the minimum battery cell temperature and the temperature of a second battery cell area with the maximum battery cell temperature.

    本公开涉及一种动力电池温度控制方法、装置以及车辆。属于电池温度控制领域,所述方法包括:获取所述动力电池的多个电芯温度,所述多个电芯温度值中的各电芯温度值分别对应所述动力电池的不同电芯区域,用于表征所述不同电芯区域当前的温度;在所述多个电芯温度中的最小电芯温度大于预设的温度第一阈值,且所述多个电芯温度中的最大电芯温度小于预设的温度第二阈值,且所述最小电芯温度与所述最大电芯温度的差值大于预设的温度差第一阈值的情况下,通过恒温模式对所述动力电池进行温度调节,以降低具备所述最小电芯温度的第一电芯区域的温度与具备所述最大电芯温度的第二电芯区域的温度之间的差值。
