The coolant system includes a first control loop thermally coupled to an energy storage system, a second control loop thermally coupled to a drive train system, a third control loop thermally coupled to a radiator system, a first multiple valve unit and a second multiple valve unit, and a first heat exchanger configured to transfer heat to the refrigerant system. The first control loop, the second control loop and the third control loop are configured to transfer heat to the first heat exchanger. The first heat exchanger is arranged between the first multiple valve unit and the second multiple valve unit. The control unit is configured to switch the first multiple valve unit and the second multiple valve unit in a first mode to couple the first control loop with the second control loop to collectively transfer heat to the first heat exchanger independently of the third control loop.

A thermal management system includes a first cooler that cools a first heat source, a first circulation path that connects the first cooler and a first pump, a second cooler that cools a second heat source, a second circulation path that connects the second cooler and a second pump, a changeover valve, and a controller. The changeover valve is switchable between first and second valve positions. The first and second circulation paths are separated from each other when the changeover valve is in the first valve position. The controller causes both the first and second pumps to operate when the temperature difference between refrigerants in the first and second circulation paths is more than a predetermined temperature difference threshold when the changeover valve is set to the first valve position and one of the first and second pumps is operating and the other is not operating.

A thermal management system includes a switching valve that switches between a first mode in which first and second flow paths are separated and a second mode in which parts of the first and second flow paths are connected. In the first mode, a control unit acquires measured values of first and second temperatures in the first and second flow paths and estimated values of the first and second temperatures when the switching valve is not in a slightly open state. The switching valve is in the slightly open state when the measured value of the first temperature is higher than the estimated value of the first temperature by a value greater than a first predetermined threshold and the measured value of the second temperature is lower than the estimated value of the second temperature by a value greater than a second predetermined threshold.
