A thermal management system comprises a coolant system and a separate refrigerant system that are both selectively interconnectable to a chiller. The coolant system includes a radiator and a plurality of fluid lines forming a selectable interconnectable array of coolant loops. This array includes an energy storage system coolant loop and an electrical drive system coolant loop that are separately interconnectable with the radiator and that control the temperature of the energy storage system and the electrical drive system of an electric vehicle. The refrigerant system includes a condenser, an internal heat exchanger, and an array of refrigerant loops that control the temperature of a cabin of the electric vehicle. Together, the coolant system and the refrigerant system provide multiple thermal control modes for components of an electric vehicle.
