A charging apparatus assigns an area ID, which is information that the charging apparatus uses to determine the presence of a vehicle, to a charging area BS and transmits the assigned area ID. Based on return of the transmitted area ID from the vehicle 200, the charging apparatus establishes pairing, which is a communication connection setting, between the charging apparatus and the vehicle. The charging apparatus then performs electric power management of the electric power transmitted from the charging area BS to the vehicle in a non-contact manner through wireless communication between the paired vehicle and charging apparatus.
