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, wherein cooling liquid is circulated in the first cooling path, and the cooling liquid passes through the battery and performs heat exchange with the battery; a second cooling path, wherein the cooling liquid is circulated in the second cooling path, and the cooling liquid passes through the motor and performs heat exchange with the motor; 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.
