Abstract
The present technique relates to a power supply device and method as well as a program which allow a billing process to be surely performed in charging a vehicle. When a vehicle ID registered in advance in an external storage matches a vehicle ID acquired by a reader/writer, a control unit controls a lock control part to fit a lock of an outlet into a hole in a projection of a plug and lock the connection between the outlet and the plug. The control unit in this state turns on a selector switch to charge a battery of an electric vehicle from a charger. Once charging has been completed, the control unit controls a billing part to calculate the amount of electric power so that a billing server performs a billing process for the amount of money corresponding to the amount of electric power.

9. A power supply device comprising:
-
a switching unit which turns on/off electric power supplied to a device through a power supply line; a reader/writer unit which reads a device ID from a storage unit included in the device by means of load modulation using a high frequency signal through the power supply line, or writes information in the storage unit of the device; a lock unit which locks connection with the device by the power supply line; and
a control unit which performs control to turn on the switching unit and supply electric power to the device through the power supply line when connection between the device and the power supply line is locked by the lock unit and, when it is requested to release the lock by the lock unit, performs control to release the lock by the lock unit once predetermined information has been written in the storage unit of the device by the reader/writer unit.

10. A power supply device comprising:
-
a power supply unit which supplies electric power from a commercial power supply to a device through a power supply line; a switching unit which turns on/off electric power supplied from the power supply unit to the device through the power supply line; a reader/writer unit which reads a device ID from a storage unit included in the device by means of load modulation using a high frequency signal through the power supply line, or writes information into the storage unit included in the device; a lock unit which locks connection with the device by the power supply line; and a control unit which performs control to turn on the switching unit and supply electric power to the device through the power supply line when connection between the device and the power supply line is locked by the lock unit and, when it is requested to release the lock by the lock unit, performs control to discontinue supplying the electric power to the device through the power supply line and release the lock by the lock unit once information has been written in the storage unit of the device by the reader/writer unit. - View Dependent Claims (11, 12, 13)

15. A power supply device comprising:
-
a power supply step in which electric power is supplied from a commercial power supply to a device through a power supply line by a power supply unit which supplies electric power from the commercial power supply to the device through the power supply line; a switching step in which electric power supplied to the device through the power supply line by the process performed in the power supply step is turned on/off by a switching unit which turns on/off electric power supplied from the power supply unit to the device through the power supply line; a read/write step in which a device ID is read from a storage unit of the device by means of load modulation using a high frequency signal through the power supply line or information is written into the storage unit of the device by a reader/writer unit which reads the device ID from the storage unit of the device by means of load modulation using the high frequency signal through the power supply line or writes the information into the storage unit of the device; a lock step in which connection with the device is locked by means of the power supply line by a lock unit which locks the connection with the device by means of the power supply line; and a control step in which control is performed to turn on the process performed in the switching step and supply electric power to the device through the power supply line when the connection between the device and the power supply line is locked by the process performed in the lock step and, when it is requested to release the lock implemented by the process performed in the lock step, control is performed to discontinue supplying the electric power to the device through the power supply line and release the lock implemented by the process performed in the lock step once information has been written into the storage unit of the device by the process performed in the read/write step, the control step being performed by a control unit which performs control to turn on the switching unit and supply electric power to the device through the power supply line when connection between the device and the power supply line is locked by the lock unit and, when it is requested to release the lock by the lock unit, performs control to discontinue supplying the electric power to the device through the power supply line and release the lock by the lock unit once the information has been written in the storage unit of the device by the reader/writer unit.

16. A program which causes a computer controlling a power supply device to execute a process comprising:
-
a power supply step in which a power supply unit supplies electric power from a commercial power supply to a device through a power supply line; a switching step in which a switching unit turns on/off electric power supplied to the device through the power supply line by the process performed in the power supply step; a read/write step in which a reader/writer unit reads a device ID from a storage unit of the device by means of load modulation using a high frequency signal through the power supply line or writes information into the storage unit of the device; a lock step in which a lock unit locks connection with the device by means of the power supply line; and a control step in which a control unit performs control to turn on the process performed in the switching step and supply electric power to the device through the power supply line when the connection between the device and the power supply line is locked by the process performed in the lock step and, when it is requested to release the lock implemented by the process performed in the lock step, performs control to discontinue supplying the electric power to the device through the power supply line and release the lock implemented by the lock unit once information has been written into the storage unit of the device by the process performed in the read/write step, wherein the power supply device includes; the power supply unit which supplies electric power from the commercial power supply to the device through the power supply line; the switching unit which turns on/off electric power supplied from the power supply unit to the device through the power supply line; the reader/writer unit which reads the device ID from the storage unit of the device by means of load modulation using the high frequency signal through the power supply line or writes the information into the storage unit of the device; the lock unit which locks connection with the device by the power supply line; and the control unit which performs control to turn on the switching unit and supply electric power to the device through the power supply line when connection between the device and the power supply line is locked by the lock unit and, when it is requested to release the lock by the lock unit, performs control to discontinue supplying the electric power to the device through the power supply line and release the lock by the lock unit once the information has been written in the storage unit of the device by the reader/writer unit.
