Abstract

A charging control apparatus (310) controls wireless charging between one charging apparatus (10) and a vehicle (20) which communicates with the one charging apparatus via a communication relay apparatus (30). The charging control apparatus is provided with: an outputting device (320, 330) for transmitting a first signal which is a signal for designating a signal outputted from the one charging apparatuses, to of the one charging apparatuses; a detecting device (320, 330) for detecting a third signal, which is transmitted by wireless communication from the vehicle and which is a signal corresponding to a second signal which is a signal outputted from the one charging apparatus due to the transmitted first signal; and a distinguishing device (310) for correlating the one charging apparatus with the vehicle on the basis of the transmitted first signal and the detected third signal.
