THERMAL MANAGEMENT SYSTEM, METHOD FOR CONTROLLING THERMAL MANAGEMENT SYSTEM, AND ELECTRIC VEHICLE

This application provides a thermal management system capable of relatively efficiently using heat generated by a motor, a method for controlling a thermal management system, and an electric vehicle. The thermal management system in this application includes a refrigerant loop and a motor coolant loop. The refrigerant loop and the motor coolant loop jointly include a low pressure chiller. The low pressure chiller is configured to enable a refrigerant in the refrigerant loop to absorb heat from a motor coolant in the motor coolant loop, to heat a target temperature-controlled space and/or a target temperature-controlled device, that is, the heat from the motor coolant is absorbed by a heat pump to implement heating. Therefore, a temperature of the motor coolant may be relatively low on a basis that a required heating temperature can be achieved, so that a difference between the temperature of the motor coolant and an ambient temperature is relatively small. In this way, heat loss caused by dissipation of heat from a motor to a surrounding environment can be reduced, thereby improving utilization of the heat from the motor.
