If the antenna is selected, the control unit 10 controls the function selection unit 72 to select the start authentication unit 60 and connect the antenna selection unit 71 to the antenna selection unit 71 (S315).

When the start authentication unit 60 and the antennas of the multiple antenna unit 40 are connected through the switching unit 70, the controller 10 controls the start authentication unit 60 to generate a start authentication request signal, After the transmission (S317), it is checked whether the startup authentication information is received in response to the startup authentication request signal (S319).

When the startup authentication information is received, the controller 10 performs authentication according to a normal startup authentication method (S321).

After the authentication, the control unit 10 terminates if the authentication result is unsuccessful. If the authentication result is successful, the control unit 10 starts the vehicle according to the normal startup method (S325), switches to the wireless charging mode, and terminates (S327).

In the above description, a case has been described in which a preset antenna is selected to supply a charging current.
