Abstract
In one aspect, a thermal management system includes a first coolant circuit, through which a first coolant circulates, and including at least a radiator for cooling the first coolant, a storage containing one or more power electronics, a heat exchanger, and a thermostatic valve that outputs the first coolant to at least one of the storage containing the one or more power electronics and the heat exchanger. A second coolant circuit, through which a second coolant circulates, includes the heat exchanger configured to cool the second coolant using the first coolant, an energy storage unit cooled by the second coolant, and a refrigeration unit configured to cool the second coolant. A coolant temperature sensor outputs a temperature of the coolant in the second coolant circuit, and a controller controls at least the refrigeration unit based on the temperature of the coolant output by the coolant temperature sensor.
