A method of operating a cooling system for a vehicle including providing a cooling system including a coolant loop having a coolant valve, a first refrigerant loop having a first compressor and a first chiller configured to exchange heat with the coolant loop, a second refrigerant loop having a second compressor and a second chiller configured to exchange heat with the coolant loop, and a cooling system controller operably coupled to the first compressor, the second compressor, and the coolant valve. The coolant valve is configured to selectively direct or prevent the flow of coolant between the battery and each of the first chiller and the second chiller. The method further includes operating the cooling system in one of a second chiller only mode, a first chiller only mode, an air conditioning (AC) only mode, a first refrigerant loop only mode, and a dual refrigerant loop mode.

Method of operating a cooling system having dual independent refrigerant loops for providing cooling to a vehicle cabin and vehicle battery

A cooling system for a vehicle including a coolant loop configured to exchange heat with a battery. The coolant loop includes a proportional valve for directing a coolant from the battery to at least one of a first chiller and a second chiller. The cooling system for a vehicle also includes a first refrigerant loop comprising the first chiller. The first chiller is configured to exchange heat between the first refrigerant loop and the coolant loop. The cooling system for a vehicle also includes a second refrigerant loop comprising the second chiller. The second chiller is configured to exchange heat between the second refrigerant loop and the coolant loop.
