Abstract

The invention discloses a battery thermal management system of a vehicle and the vehicle. The battery thermal management system includes an air-conditioning circulating system and a battery pack heatexchange system. The battery pack heat exchange system comprises a heat exchanger, a heater, a pump body, a controller, a temperature sensor and a battery pack heat exchange part, wherein the air-conditioning circulating system selectively provides cold energy or heat energy for the heat exchanger. The heat exchanger, the heater, the pump body and the battery pack heat exchange part are communicated; the battery pack heat exchange part is arranged on the battery pack, the heater, the pump body and the temperature sensor are all electrically connected with the controller, and the controller selectively controls the heater to work according to the temperature detection result of the temperature sensor. Therefore, through the cooperation of the air-conditioning circulating system and the battery pack heat exchange system, the problems of overheating and supercooling of the battery pack can be effectively solved, and the battery pack can be ensured to work normally under any working condition.
