Abstract
A cooling system for a rechargeable energy storage system (RESS) of a vehicle includes a coolant circuit configured to direct a coolant flow through the RESS to remove thermal energy from the RESS, and a refrigerant circuit through which a flow of refrigerant is circulated. A chiller is fluidly connected to the coolant circuit and the refrigerant circuit and is configured to transfer thermal energy between the coolant circuit and the refrigerant circuit. An auxiliary circuit is fluidly connected to the coolant circuit. The auxiliary circuit is configured to selectably direct at least a portion of the coolant flow across a first side of a cold plate for thermal energy exchange with a phase change material located at a second side of the cold plate. One or more valves are configured to selectably direct the at least a portion of the coolant flow through the auxiliary circuit.
