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 battery and/or an electric motor of the electric vehicle, the system comprising:
- a first cooling path on which the battery is located, wherein a cooling liquid is circulated in the first cooling path, and the first cooling liquid passes through the battery and performs heat exchange with the battery;
a second cooling path on which the electric motor is located, wherein the cooling liquid is circulated in the second cooling path, and the second cooling liquid passes through the motor and performs heat exchange with the motor, and wherein the first and second cooling paths are separate and independent from each other; and
a first radiator, wherein the first radiator provides a heat source to the passenger cabin by dissipating the heat absorbed by at least one of the cooling liquids flowing in the first and second cooling paths, and wherein the first radiator is selectively connected to at least one of the first and second cooling paths.

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.
