A method of operating an electric vehicle (EV) thermal management system, the EV thermal management system comprising a refrigerant-based thermal control loop (121) coupled to a refrigerant-air heat exchanger (127), a coolant-based thermal control loop (101) coupled to a liquid-air heat exchanger (105), a heat pump (401) integral to the refrigerant-based thermal control loop (121) with a heat pump condenser (403) coupleable to the coolant-based thermal control loop (121), wherein the refrigerant-air heat exchanger (127) and the liquid-air heat exchanger (105) are located within a passenger cabin air intake pathway, the method utilizing the heat pump (401) to permit efficient air recirculation by the vehicle's HVAC system, thereby increasing driving range, especially in cold weather conditions.
