THERMAL MANAGEMENT SYSTEM AND ELECTRIC VEHICLE

This application provides a thermal management system and an electric vehicle. The thermal management system includes a battery water circuit and a seat water circuit. The battery water circuit includes a cooling water pump and a battery cooling/heating plate connected through a cooling water pipe. The seat water circuit has a liquid inlet end and a liquid outlet end. The liquid inlet end is connected between a liquid outlet of the cooling water pump and a liquid inlet of the battery cooling/heating plate through a seat water pipe and the cooling water pipe, and the liquid outlet end is connected between a liquid inlet of the cooling water pump and a liquid outlet of the battery cooling/heating plate through the seat water pipe and the cooling water pipe. A liquid medium in the battery water circuit may enter the seat water circuit from the liquid inlet end. The seat water circuit includes a seat heat exchange branch. The seat heat exchange branch includes a seat heat exchanger and a branch control valve. The branch control valve is disposed between the liquid inlet end and the seat heat exchanger and is configured to control a temperature of a liquid medium in the seat heat exchanger. By using the thermal management system provided in this application, the seat water circuit can be cooled by using the battery water circuit, to improve energy efficiency of the thermal management system.
