Abstract
A heat pump system includes a refrigerant loop and a coolant loop. The refrigerant loop includes a compressor, a water condenser, an expansion valve, and a chiller. The coolant loop includes two water pumps, a one-way valve, six three-way valves, a cabin cooler, a cabin heater, a battery pack, and an electric drive system. An electric heater is used to generate additional heat power for cabin heating. A fan and a blower are used to control the front end and cabin airflow. The heat pump system provides a simplified thermal design for electric vehicles while providing efficient thermal management of the cabin and the powertrain system.
