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.
