VEHICLE THERMAL MANAGEMENT SYSTEM AND VEHICLE

Provided are a thermal management system applied in a vehicle, and the vehicle. The thermal management system includes a cooling circuit (10), a thermostatic circuit (20), a heating circuit (30), and an expansion tank (40). The cooling circuit (10), the thermostatic circuit (20), and the heating circuit (30) are all connected to the expansion tank (40), and the expansion tank is configured for liquid-filling and air-exhausting of the cooling circuit (10), the thermostatic circuit (20), and the heating circuit (30). In the thermal management system, the cooling circuit (10), the thermostatic circuit (20), and the heating circuit (30) are connected by using one expansion tank, thereby reducing the cost of the vehicle, improving a coolant-filling efficiency of the expansion tank and a production takt on the vehicle production line, and improving the after-sales maintenance efficiency of the vehicle.
