The invention relates to a vehicle charging control method and device, a vehicle and a storage medium, and relates to the technical field of charging, and the method comprises the steps: obtaining a rotor position, determining target bridge arms and target currents corresponding to the target bridge arms according to the rotor position, and controlling the target bridge arms according to the target currents, and the power supply equipment charges the battery through the target motor winding corresponding to the target bridge arm and the target bridge arm. The motor and the motor driving module existing on the vehicle can be reused to convert the voltage provided by the power supply equipment into the voltage required by the battery and charge the battery, the weight of the whole vehicle and the cost of the vehicle can be reduced, the usable space in the vehicle can be improved, the target current corresponding to the target bridge arm can be selected according to the position of the rotor, and the service life of the vehicle is prolonged. The target bridge arm is controlled to charge the battery, so that the number of motor windings connected in parallel when the battery is charged can be reduced, the inductance value of the motor for boosting is improved, and thus the current ripple when the battery is charged is reduced.
