In one aspect of a vehicle charging apparatus, a vehicle charging control method, and a vehicle charging system of the present invention, there is provided a charging circuit, an input side of the charging circuit being connected to an external power source via a first switching device and an output side of the charging circuit being connected to a vehicle driving battery in the order of a DC/DC converter and a second switching device, in which the DC/DC converter is connected to an auxiliary battery. When the voltage of the auxiliary battery drops, the charging circuit is actuated in a state in which the second switching device is open to start charging the auxiliary battery, and then the second switching device is closed to start charging the vehicle driving battery. This allows stable charging of the vehicle driving battery even when the auxiliary battery is in the voltage drop situation.
