Abstract
This application provides an electric vehicle thermal management system, including an air-cooled evaporator, an air-cooled condenser, a refrigerant loop system, and a coolant loop system. The coolant loop system includes five passages: a first passage connects to a water-cooled condenser and a liquid-cooled module; a second passage connects to a water-cooled evaporator; a third passage connects to a battery pack; a fourth passage connects to a radiator module; and a fifth passage connects to a powertrain. The five passages are connected by a valve group to allow at least two passages to communicate with each other. The refrigerant loop system includes a compressor, a first expansion valve, and a second expansion valve. The compressor and the water-cooled condenser are connected in series, forming a first branch and a second branch. The first branch connects to the compressor via the first expansion valve and the air-cooled evaporator, and the second branch connects to the compressor via the second expansion valve and the water-cooled evaporator. This application provides an electric vehicle thermal management system that can improve the integration of the thermal management system.
