Current control method and device, vehicle and storage medium

The invention discloses a current control method and device, a vehicle and a storage medium, and the method comprises the steps: carrying out the initial adjustment of a current output current according to the demand current of a power battery and the current output current and current output voltage of a vehicle-mounted charger, and obtaining a next output current; and according to the next output voltage of the vehicle-mounted charger, the maximum output current corresponding to the next output voltage, the required current of the power battery, the next charging current and a preset difference current, determining that the next output current meets a current safety adjustment condition, and carrying out safety adjustment on the next output current, and obtaining a new next output current; and if the new next output current meets the current safety adjustment condition, continuing to carry out safety adjustment on the new next output current until the vehicle-mounted charger finishes charging the power batt
