Abstract
Electric vehicle thermal management systems and electric vehicles using the thermal management system, are disclosed. A passenger cabin is heated by the heat dissipated from a battery and/or a motor. A cooling circuit in the management system fluidly connects the battery, the motor and a first radiator in series. The first radiator provides a heat source to the passenger cabin by means of the heat dissipated from the battery and/or the electric motor. Under certain conditions, the electric motor is selectively separated from the cooling circuit, so that when the passenger cabin needs to be heated, the thermal management system can provide heat to the passenger cabin without affecting the heat dissipation of the battery.
