Information providing system, power receiving device, information providing method and information providing program

A power receiver which is mounted on a moving object and is able to receive power fed from a power transmitter in a wireless power transfer system including one or more power transmitters installed in one or more charging stations, the power receiver comprising:

• an ID storage unit configured to store a power receiver ID for identifying the power receiver;
• and
• an ID providing unit configured to output the power receiver ID to an information providing system that provides information about the wireless power transfer system,
• wherein the information providing system extracts location information of a charging station in which a power transmitter capable of feeding power to the power receiver is installed, by referring to a station storage unit that stores station information indicating correspondence between the location information of the charging station and the power transmitter of the charging station and to a history storage unit that stores a usage history indicating one or more power transmitters previously used by the power receiver, by using the power receiver ID output from the ID providing unit,
• wherein the information providing system outputs the extracted location information of the charging station,
• wherein the usage history further indicates an actual value of power feeding performance of each of the power transmitters, and
• wherein the information providing system extracts the location information of the charging station having the power transmitter in which the actual value of the power feeding performance satisfies a reference value.

An information providing method to be executed by a computer system for providing information about a wireless power transfer system including a power receiver mounted on a moving object and one or more power transmitters installed in one or more charging stations, the information providing method comprising:

• a search step of extracting location information of a charging station in which a power transmitter capable of feeding power to the power receiver is installed, by referring to a station storage unit that stores station information indicating correspondence between the location information of the charging station and the power transmitter of the charging station and to a history storage unit that stores a usage history indicating one or more power transmitters previously used by the power receiver;
• and
• an output step of outputting the location information of the charging station extracted in the search step,
• wherein the usage history further indicates an actual value of power feeding performance of each of the power transmitters, and
• wherein the search step including a step of extracting the location information of the charging station having the power transmitter in which the actual value of the power feeding performance satisfies a reference value.

A non-transitory recording medium storing an information providing program for causing a computer to function as an information providing system for providing information about a wireless power transfer system including a power receiver mounted on a moving object and one or more power transmitters installed in one or more charging stations, the computer functioning as:

• a search unit configured to extract location information of a charging station in which a power transmitter capable of feeding power to the power receiver is installed, by referring to a station storage unit that stores station information indicating correspondence between the location information of the charging station and the power transmitter of the charging station and to a history storage unit that stores a usage history indicating one or more power transmitters previously used by the power receiver;
• and
• an output unit configured to output the location information of the charging station extracted by the search unit,
• wherein the usage history further indicates an actual value of power feeding performance of each of the power transmitters, and
• wherein the search unit extracts the location information of the charging station having the power transmitter in which the actual value of the power feeding performance satisfies a reference value.
