The invention provides an electric vehicle thermal management system and an electric vehicle. The system comprises a controller, a heat pump system, an electric drive loop, a battery loop and a control valve. The controller is used for obtaining the environment temperature outside the vehicle, the water temperature of the electric drive loop and the water temperature of the battery loop. The controller is further used for controlling the control valve to conduct the heat pump system, the electric drive loop and the battery loop when a first difference value between the water temperature of the electric drive loop and the ambient temperature outside the vehicle is within a first temperature difference range and a second difference value between the water temperature of the electric drive loop and the water temperature of the battery loop is within a second temperature difference range. And the heat generated by the electric drive loop is transferred to the battery loop. According to the system, the battery heating efficiency is improved, and the heat preservation effect of the battery is improved.
