The invention discloses a discharging control method of a vehicle-mounted charging circuit, the vehicle-mounted charging circuit, a vehicle-mounted charger and a storage medium, and relates to the technical field of vehicle-mounted charging. The vehicle-mounted charging circuit has a first working state and a second working state, and comprises: an alternating current input end and a direct current output end; a filter capacitor connected with the alternating current input end; a pre-charging resistor connected with the alternating current input end and the filter capacitor; and a switch bridge arm circuit connected with the pre-charging resistor. In the first working state, the pre-charging resistor is short-circuited; and in the second working state, the switch bridge arm circuit and the pre-charging resistor form a discharging loop so as to discharge the filter capacitor. The safety of the vehicle-mounted charger is improved, the size and production cost of the vehicle-mounted charger are reduced, and the voltage conversion efficiency of the vehicle-mounted charger is improved.
