Abstract: A thermal management system includes a circulation channel that connects a motor cooler, outside air heat exchanger, and a heater, a switching valve, and a controller. In a heating mode of operating the heater, the controller sets the switching valve in the first valve position when the motor temperature is lower than a motor temperature threshold value, and sets the switching valve in the second valve position when the motor temperature is higher than the motor temperature threshold value. When a load or a load predicted value of the motor exceeds a load threshold value, the controller holds the switching valve in the second valve position during a predetermined holding time.
