Abstract

A charging control apparatus (310) controls wireless charging between one charging apparatus (10) and a vehicle (20) which communicates with the one charging apparatus via a communication relay apparatus (30). The charging control apparatus is provided with: an outputting device (320, 330) for transmitting a first signal which is a signal for designating a signal outputted from the one charging apparatuses, to of the one charging apparatuses; a detecting device (320, 330) for detecting a third signal which is transmitted by wireless communication from the vehicle and which is a signal corresponding to a second signal which is a signal outputted from the one charging apparatus due to the transmitted first signal; and a distinguishing device (310) for correlating the one charging apparatus with the vehicle on the basis of the transmitted first signal and the detected third signal.

Claims

1. A charging control apparatus for controlling a plurality of charging apparatuses, each of the charging apparatuses being configured to be capable of supplying electric power to a vehicle through a predetermined power supplying path, wherein

the charging control apparatus is configured to perform pairing between the vehicle and one of the plurality of charging apparatuses based on a signal outputted from the vehicle which detects a first electric power having predetermined power pattern, the first electric power is supplied from the one of the plurality of charging apparatuses to the vehicle via the predetermined power supplying path,

the charging control apparatus is configured to control at least one charging apparatus such that at least one charging apparatus supplies the first electric power to the vehicle after receiving a request for starting the pairing via wireless communication.

4. The charging control apparatus according to claim 1, wherein

the wireless communication allows the communication with the vehicle.

5. The charging control apparatus according to claim 1, wherein

the wireless communication does not uses the predetermined power supplying path as a communication path.

6. The charging control apparatus according to claim 1, wherein

the predetermined power supplying path is a path which is used to supply second electric power for charging a battery of the vehicle.

8. A non-transitory computer readable recording medium recording thereon a computer program, wherein

the computer program makes a computer function as the charging control apparatus according to claim 1.

2. A charging control apparatus mounted on a vehicle to which each of a plurality of charging apparatuses supplies electric power through a predetermined power supplying path, wherein

the charging control apparatus is configured to output signal, which is used to perform pairing between the vehicle and one of the plurality of charging apparatuses, based on a detection result of a first electric power having predetermined power pattern, the first electric power is supplied from the one of the plurality of charging apparatuses to the vehicle via the predetermined power supplying path,

the charging control apparatus is configured to transmit, via wireless communication, a request for starting the pairing to another charging control apparatus which controls the plurality of charging apparatuses, the request allows at least one charging apparatus to supplies the first electric power to the vehicle.

3. A charging control apparatus mounted on one of a plurality of charging apparatuses, each of the plurality of charging apparatuses being configured to be capable of supplying electric power to a vehicle through a predetermined power supplying path, wherein

the charging control apparatus is configured to supply a first electric power having predetermined power pattern to the vehicle via the predetermined power supplying path such that pairing between the vehicle and the one of the plurality of charging apparatuses is performed based on a signal outputted from the vehicle which detects the first electric power,

the charging control apparatus is configured to supply the first electric power to the vehicle after another charging control apparatus which controls the plurality of charging apparatuses receives, via wireless communication, a request for starting the pairing, the request allows at least one charging apparatus to supplies the first electric power to the vehicle.

7. A charging control method of controlling a plurality of charging apparatuses, each of the plurality of charging apparatuses being configured to be capable of supplying electric power to a vehicle through a predetermined power supplying path, wherein

the charging control method performs pairing between the vehicle and one of the plurality of charging apparatuses based on a signal outputted from the vehicle which detects a first electric power having predetermined power pattern, the first electric power is supplied from the one of the plurality of charging apparatuses to the vehicle via the predetermined power supplying path,

the charging control method controls at least one charging apparatus such that at least one charging apparatus supplies the first electric power to the vehicle after receiving a request for starting the pairing via wireless communication.
