摘要:
A capacitor is configured to be in thermal contact with an electrical load. A controller is configured to charge and discharge the capacitor to change a temperature of the capacitor. The controller is configured to selectively discharge the capacitor at a discharge current at which entropic cooling of the capacitor is greater than Joule heating of the capacitor to provide cooling for the electrical load.

Disclosed herein is a battery pack thermal management system for an electric vehicle. The battery pack thermal management system includes a refrigerant cycle circuit in which refrigerant is circulated through a compressor, a condenser, an expander, and an evaporator, a coolant circulation circuit in which water is circulated through a battery pack by a circulation pump, and a heat exchange module disposed to share portions of the refrigerant cycle circuit and the coolant circulation circuit, so as to exchange heat between the water and the refrigerant branched from the refrigerant cycle circuit to cool the battery pack using the water or so as to electrically heat the water and then heat the battery pack using the heated water. Consequently, it is possible to reduce costs and weight and improve the degree of design of peripheral components.
