The invention provides a charging circuit, a control method of the charging circuit and an electric vehicle, and relates to the technical field of electric vehicles, the charging circuit comprises a first switch, a driving motor and a driving motor control unit; one end of the first switch is connected with a DC charging port, and the other end is connected with a third winding of the driving motor; direct current input from the direct current charging port flows to the third winding through the closed first switch; direct current flowing into the third winding flows to the first winding and the second winding of the driving motor; direct current flowing into the first winding and the second winding is boosted by a boosted circuit formed by the first winding, the second winding and the driving motor control unit and then flows to a power battery. High-power parts in the electric vehicle are greatly reduced, the number of components in the whole charging circuit is small, the circuit line is simple, the space occupancy rate is greatly reduced, and meanwhile the cost of the electric vehicle is well reduced.

    本发明提供了一种充电电路、充电电路的控制方法及电动汽车,涉及电动车技术领域,所述充电电路包括:第一开关、驱动电机以及驱动电机控制单元;第一开关的一端与直流充电口连接,另一端与驱动电机的第三绕组连接;直流充电口输入的直流电,经闭合的第一开关流向第三绕组;第三绕组流入的直流电,流向驱动电机的第一绕组、第二绕组;第一绕组、第二绕组流入的直流电,经第一绕组、第二绕组以及驱动电机控制单元构成的升压电路升压后,流向动力电池。本发明极大的减少了电动汽车中的大功率零部件,整个充电电路中元器件很少,电路线路简洁,极大的减少了空间占用率的同时,还极好的降低了电动汽车的成本。
