A charging system includes a vehicle (200) that receives electric power with which a storage battery (240) is charged, from an inlet (226), and a power feeding apparatus (100) that supplies the electric power to a power-feed-side connector (126) connected to the inlet (226). The power feeding apparatus (100) and the vehicle (200) share a temporary signal pattern given to a control signal, through communication via communication units (130, 270), separately from communication established by connection between the inlet (226) and the power-feed-side connector (126). The vehicle (200) specifies the power feeding apparatus (100) as a destination of wireless communication, as the apparatus connected to the inlet (226), based on matching of a temporary signal pattern detected from the control signal, with the shared temporary signal pattern.
