Abstract

A center server includes a receiver that receives position information transmitted from an electric vehicle that can be charged externally, a processing unit and a storage device. The position information is on a charging facility at which the electric vehicle has been charged. The processing unit determines a standard or specification of the charging facility based on the position information received by the receiver, and associates standard/specification information indicating the standard or specification of the charging facility with the position information on the charging facility, and stores the associated information in the storage device.

the information relating to whether the power source type of the charging facility is alternate current or direct current, or the information relating to the magnitude of the power source voltage.

4. The center server according to claim 1, wherein the processing unit

determines whether the charging facility, the position information on which is received by the receiver, is a facility that is able to be used by an unspecified user, and

when the processing unit determines that the charging facility is able to be used by the unspecified user, the processing unit associates the position information with the standard/specification information pertaining to the charging facility, and registers the associated information in the storage device.

5. The center server according to claim 4, wherein

the receiver receives identification information of the electric vehicle that transmits the position information on the charging facility, from the electric vehicle that is able to be charged externally at the charging facility;

the processing unit determines, on the basis of the identification information of the electric vehicle that is able to be charged externally at the charging facility, whether the position information pertaining to the same charging facility is received from a predefined number or more of electric vehicles; and

when the processing unit determines that the position information pertaining to the same charging facility is received from the predefined number or more of electric vehicles, the processing unit determines that the charging facility is able to be used by the unspecified user.

6. The center server according to claim 1, wherein the processing unit decides an accuracy of registered information pertaining to each charging facility.

7. The center server according to claim 6, wherein as the number of electric vehicles, from which the receiver has received the position information relating to the same charging facility, increases, the processing unit increases the accuracy of the registered information pertaining to the charging facility.

8. A charging facility registration system comprising:

the center server according to claim 1; and

an on-board device that is installed in the electric vehicle that is able to be charged externally at the charging facility, and that transmits to the center server at least the position information upon completion of charging, in the charging facility, of the electric vehicle on which the on-board device is installed.

11. The center server according to claim 1, wherein

the processing unit is further programmed to determine the at least one of the standard or the specification of the charging facility on the basis of identification information of the electric vehicle that is able to be charged externally at the charging facility, and

the identification information includes at least one of:

an on-board device identification, a vehicle identification number (VIN), or a vehicle model of the electric vehicle.

13. The center server according to claim 1, wherein the processing unit is programmed to determine the at least one of the standard or the specification of the charging facility on the basis of the charging incompatibility notification transmitted from the electric vehicle that is not able to be charged externally at the charging facility.

9. A charging facility registration method comprising:

receiving, by a center server, position information transmitted from an electric vehicle that is able to be charged externally, the position information being on a charging facility at which the electric vehicle that is able to be charged externally has been charged, and receiving, by the center server, a charging incompatibility notification from an electric vehicle that is not able to be charged externally at the charging facility;

determining, by the center server, at least one of a standard or a specification of the charging facility pertaining to the received position information, wherein the center server is located remotely from the charging facility;

associating, by the center server, standard/specification information indicating the at least one of the standard or the specification of the charging facility with the position information on the charging facility, wherein the at least one of the standard or the specification of the charging facility includes a category or charger type of the charging facility;

storing the associated information in a storage device; and

providing an update to another electric vehicle that is not the electric vehicle that is able to be charged externally at the charging facility by transmitting displayable information based on the determined at least one of the standard or the specification of the charging facility and the position information of the charging facility, wherein
