Abstract:
A power supply system includes an authentication server. Before receiving power supplied from a power supply coil of a power supply apparatus, an electric vehicle is authenticated by the authentication server. For receiving power supplied from the power supply coil, the electric vehicle gives a power-supply request to request a power-supply controller, which controls the power supply apparatus, to issue a temporary ticket for receiving power supply. The electric vehicle transmits the temporary ticket to the power supply apparatus, and upon determining that the temporary ticket is legitimate, the power supply apparatus executes power supply.
