Electric vehicle thermal management system
First Claim
1. An electric vehicle thermal management system for heating a passenger cabin of an electric vehicle by means of the heat absorbed from a first component and/or a second component of the electric vehicle, the system comprising:
- a first cooling path, wherein cooling liquid is circulated in the first cooling path, and the cooling liquid passes through the first component and performs heat exchange with the first component;
a second cooling path, wherein the cooling liquid is circulated in the second cooling path, and the cooling liquid passes through the second component and performs heat exchange with the second component;
a third cooling path, wherein the third cooling path comprises an inlet and an outlet, and the inlet and the outlet are in fluid communication; and
wherein, the cooling liquid flows through at least one of the first cooling path and through the second cooling path,wherein when the cooling liquid flows through the first cooling path and through the second cooling path, the cooling liquid from the first cooling path and the cooling liquid from the second cooling path converge at the inlet of the third cooling path, flow through the third cooling path and then divide at the outlet of the third cooling path to re-flow into the first cooling path and the second cooling path.

Abstract
An electric vehicle thermal management system and an electric vehicle using the thermal management system, wherein a passenger cabin is heated by the heat dissipated from a battery and/or a motor, and the battery and the electric motor are connected in different cooling paths. Heat is supplied to the passenger cabin by using the heat absorbed by cooling liquid from the battery and/or the motor, so that the electric power of the electric vehicle can be effectively utilized to increase the endurance mileage of the electric vehicle.
