The invention relates to an electric driving system for a vehicle and a charging control method. The electric driving system for the vehicle comprises a driving motor, a relay and a motor controller, the driving motor comprises a three-phase winding and a three-phase inverter bridge circuit; the output end of the three-phase winding is connected with the input end of the three-phase inverter bridge circuit; the motor controller comprises a three-phase rectifier bridge circuit and a control circuit; the three-phase rectifier bridge circuit is connected with the first end of the relay; the second end of the relay is connected with the neutral point of the three-phase winding; the control circuit is connected with the three-phase inverter bridge circuit and the three-phase rectifier bridge circuit so as to control on-off of a switch tube of the three-phase inverter bridge circuit and on-off of a switch tube of the three-phase rectifier bridge circuit. A three-phase rectifier bridge circuit is added to form a charging circuit with a driving motor in a vehicle electric driving system, so that a vehicle-mounted charger is replaced, and based on good heat dissipation conditions of a motor controller and the driving motor and support of the motor controller and the driving motor on high-power input, the charging power is improved, and the charging duration is shortened.
