A vehicle thermal management system includes a heat pump system, a coolant loop that transfers heat energy between a battery and a cabin heating, ventilation, and air-conditioning (HVAC) module. The heat pump system can be an air-source heat pump or coolant-based heat pump with a water condenser. The coolant loop includes a low-temperature cooling system that rejects coolant heat to the ambient environment through a radiator. The cabin HVAC module includes a blower, a vent door, a cabin heater, and an evaporator. The coolant loop of the thermal management system includes an electric water pump, a chiller, a cabin heat exchanger, a three-way valve, and a one-way valve. The vehicle thermal management system can take advantage of a temperature difference between cabin exhaust air and battery coolant for heating and cooling, which reduces system power consumption.
