The invention provides a charging circuit, a charging system and an electric vehicle, and relates to the technical field of electric vehicles. The charging circuit comprises a motor and a motor control loop. A charging leading-out wire of each phase winding in the motor is connected with a resonant full-bridge converter; the wire outlet end of each phase of winding in the motor is connected with the motor control loop; the alternating current output by the resonant full-bridge converter is input from the charging lead-out wire and output to the motor control loop from the wire outlet end; and the motor control loop rectifies and filters the alternating current output from the wire outlet end and outputs rectified and filtered direct current to a power battery. The winding and the control loop of the motor are multiplexed, boosting is achieved through the motor winding, rectification and filtering are achieved through the control loop of the motor, components used by a transformer, a full-bridge rectification module and a filtering module are omitted, a circuit line is simple, the space occupancy rate is reduced, and due to the fact that the components are omitted, the cost of an electric automobile is indirectly reduced, and the high practicability is achieved.

    本发明提供了一种充电电路、充电系统以及电动汽车,涉及电动车技术领域,所述充电电路包括:电机、电机控制回路;电机中每相绕组的充电引出线与谐振全桥变换器连接;电机中每相绕组的出线端与电机控制回路连接;谐振全桥变换器输出的交流电,从充电引出线输入,从出线端输出至电机控制回路;电机控制回路对从出线端输出的交流电进行整流滤波,向动力电池输出整流滤波后的直流电。本发明复用电机的绕组和控制回路,利用电机绕组实现升压,利用电机的控制回路实现整流、滤波,省去了变压器、全桥整流以及滤波模块所使用的元器件,不但使得电路线路简洁,还减少了空间占用率,并且由于元器件的省去,间接降低了电动汽车的成本,具有较高的实用性。
