Thermal management control method and device for power battery of electric vehicle

The invention discloses an electric vehicle power battery thermal management control method and device, and the method comprises the steps: determining a thermal management mode of a battery according to the average temperature of the battery and/or the current operation condition of a vehicle, and determining the target temperature of the battery according to the temperature of the battery and/or the environment temperature and/or the SOC of the battery; heating or cooling the battery to a target temperature or maintaining the current temperature by adopting the thermal management mode; by utilizing the method and the device, the temperature requirement of the battery can be accurately controlled and met, and energy is saved to the maximum extent; when the environment temperature is extremely low and the available power of the power battery is insufficient, the available power of the battery is recovered as soon as possible; meanwhile, battery temperature is balanced, and excellent working performance of the
