The invention discloses a vehicle-mounted charger, a vehicle and a charging method of the vehicle, and relates to the technical field of new energy vehicles. The vehicle-mounted charger comprises a resonance circuit, wherein the resonance circuit comprises a three-phase winding of a generator and a relay unit connected with the three-phase winding; under the condition that the relay unit is in a disconnected state, the vehicle-mounted charger works in a range extending power generation state, and the resonance circuit is used for providing control voltage for a three-phase winding of the generator so as to control the generator and a range extending engine in mechanical linkage with the generator to rotate. And alternating current electric energy generated by rotation of the range extending engine and the generator is rectified and output to a battery pack of the vehicle. The vehicle-mounted charger is reused as the generator controller, the generator and the range extending engine in mechanical linkage with the generator are controlled to rotate to generate electric energy, the part utilization rate is increased, and the vehicle cost, the weight, the power consumption and the occupied space are reduced.
