Abstract: The present disclosure discloses a temperature adjustment method including: obtaining a required power for temperature adjustment on a battery; obtaining an actual power for temperature adjustment on the battery; and adjusting a temperature of the battery according to the required power for temperature adjustment and the actual power for temperature adjustment. The present disclosure may precisely control a temperature adjustment time of the battery, and the actual power for temperature adjustment on the battery is adjustable in real time, so that a heating power and a cooling power of the vehicle-mounted battery may be precisely controlled according to an actual status of the vehicle-mounted battery, thereby adjusting the temperature of the vehicle-mounted battery when the temperature is excessively high or excessively low, maintaining the temperature of the vehicle-mounted battery within a preset range, and avoiding a case of affecting performance of the vehicle-mounted battery because of the temperature.
