The invention provides a power battery temperature adjusting method, and relates to the field of electric automobiles. When the temperature of a power battery is judged to be smaller than a minimum working temperature threshold value, it is indicated that the temperature of the power battery is too low and heating needs to be conducted, and if the outlet temperature of a cooling loop of a motor is larger than a preset outlet temperature, it is indicated that waste heat generated during operation of the motor can be used for heating the power battery, the waste heat generated during operation of the motor is used for heating the power battery, and therefore the temperature of the power battery is reasonably and effectively adjusted according to the actual working condition of the vehicle.
本申请提供了动力电池温度调节方法,涉及电动汽车领域,当判断出动力电池温度小于最低工作温度阈值时,则说明动力电池温度过低,需要进行加热,如果此时电机的冷却回路的出口温度大于预设出口温度,说明电机运转时产生的余热可以用于加热动力电池,则利用电机运转时产生的余热来对动力电池进行加热,从而根据车辆的实际工况,合理且有效地调节动力电池的温度。
