ELECTRIC VEHICLE THERMAL MANAGEMENT SYSTEM WITH SERIES AND PARALLEL STRUCTURE

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 101, the motor 102 and a first radiator 104 in series. The first radiator 104 provides a heat source to the passenger cabin by means of the heat dissipated from the battery 101 and/or the electric motor 102. 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 101.
