Disclosed is an apparatus of using a double-winding motor control topology for equivalent implementation of charging by a vehicle-mounted charger. The apparatus comprises a battery module, a switch assembly, a first-phase bridge arm, a second-phase bridge arm, a third-phase bridge arm, a fourth-phase bridge arm, a fifth-phase bridge arm, a sixth-phase bridge arm, a seventh-phase bridge arm, a capacitor C1, a capacitor C2, a first winding, a second winding, a third winding, a fourth winding, a fifth winding, and a sixth winding. A first working mode and a second working mode are formed by controlling the on and off of the switch assembly. The first working mode is a double-winding motor control mode, in which the switch assembly is controlled such that the first-phase bridge arm is in a cut-off state, and the capacitor C1, the second-phase bridge arm, the third-phase bridge arm and the fourth-phase bridge arm form a first double-winding motor power control module. According to the present invention, a vehicle-
