Once the information determining the amount of electric power to be charged has been input, the control unit controls a billing part to calculate the amount of electric power, so that a billing server performs a billing process on the amount of money corresponding to the amount of electric power. The control unit then controls a communication unit and turns on a selector switch.

Abstract: A control unit controls a reader/writer to generate a vehicle ID read signal that is formed of a high frequency signal and used to read a vehicle ID recorded in an ID circuit, and supply the signal to a high-pass filter. The read signal or a write signal formed of the high frequency signal is superimposed on a power supply line and supplied to the high-pass filter. The high-pass filter supplies the vehicle ID read signal formed of the high frequency signal to the ID circuit.

An authentication part of the control unit turns on a selector switch when the vehicle ID being the response signal is determined to be legitimate.
