It is assumed that (hereinafter collectively referred to as electric power company E) and a plurality of electric vehicles Va, b, c,... (Hereinafter collectively referred to as electric vehicles V) are present. The charging infrastructure information provision system 100 is a system for providing information on the charging infrastructure S to the user of the electric vehicle V. More specifically, the charging infrastructure information provision system 100 preferentially provides, to the user of the electric vehicle V, information on the charging infrastructure S that greatly contributes to the contribution of the predetermined attribute to the power supply. Here, the attribute is, for example, information indicating which power generation method is used to generate the power. The power generation system is roughly classified into a power generation system that uses renewable energy and a power generation system that uses depletable energy. Renewable energy includes energy such as wind, solar, hydro and biomass. Depletable energy includes energy such as petroleum, natural gas, oil sands, methane hydrate, uranium and the like. In addition, contribution refers to an action in which the charging infrastructure S preferentially adopts power of a predetermined attribute, and specifically, energy with low environmental load such as renewable energy is preferentially substituted for exhaustible energy.

As an evaluation method that refers to the absolute value, for example, the charging station Sa supplies 10 (kW) of power of a predetermined attribute, and the charging station Sb supplies 20 (kW) of power of the predetermined attribute. In this case, it is evaluated that the charging station Sb contributes to the power supply of a predetermined attribute rather than the charging station Sa. On the other hand, in the evaluation method referring to the relative value, for example, the charging station Sa supplies power of 100 (kW) of various attributes, of which 10 (kW) of power of a predetermined attribute is supplied. In the case where the station Sb supplies power of 400 (kW) of various attributes and supplies 20 (kW) of power of the predetermined attribute among them, the charging infrastructure Sa of the power of various attributes is The rate at which the power of the predetermined attribute is supplied is 10 (%), and the rate at which the charging infrastructure Sb is supplying the power of the predetermined attribute is 5 (%).

  FIG. 7 illustrates an example of an operation sequence of charging infrastructure information provision device 110, charging infrastructure device 130, power company device 150, and on-vehicle device 170. This operation sequence is evaluated with reference to the absolute value of the power supply amount generated by solar power generation as an evaluation of the contribution to the power supply of a predetermined attribute, to the supply of the power generated by solar power generation. The information on the charging infrastructure S that greatly contributed to the contribution is preferentially shown to the on-board unit 170 of the electric vehicle V. Furthermore, this operation sequence refers to FIGS. 1 to 6 together.

  It is assumed that the charging infrastructure S is provided with a commercial power source as a power source. Then, it is assumed that the grid power generated by the power company E with which the charge infrastructure S operator has contracted is supplied to the commercial power source. And each electric power company E assumes that the attribute information of the system power generated in its own is released. For example, each electric power company E is assumed that the electric power company apparatus 150 publishes WWW (World Wide Web) attribute information of the system power generated in its own company. In that case, the attribute information acquisition unit 131 of the charging infrastructure device 130 acquires the attribute information of the grid power published by the power company device 150 (S101). For example, when power generated by a plurality of power generation methods is mixed and supplied as grid power, the attribute information of the grid power is information indicating the ratio of the amount of power generated by each power generation method. Then, the attribute information acquisition unit 131 stores the acquired attribute information of the system power in the attribute information storage unit 135 (S102). Thus, the attribute information storage unit 135 of the charging infrastructure device 130 is attribute information of the system power generated by the contracting electric power company E as shown in FIG. 6 and supplied from the commercial power source to the charger. Will be stored.

  In addition, in the charging infrastructure S, a solar power generation system and a storage battery may be further provided as an electric power source. In that case, the attribute information generation unit 132 of the charging infrastructure device 130 generates attribute information of the power generated by the solar power generation system and supplied from the storage battery to the charger (S103). For example, the attribute information generation unit 132 generates information indicating that the solar power generation is 100 (%) as the attribute information of the power. Then, the attribute information generation unit 132 stores the generated attribute information of the power in the attribute information storage unit 135 (S104). In this manner, the attribute information storage unit 135 stores attribute information of power generated by the solar power generation system and supplied from the storage battery to the charger as shown in FIG.

  The power supplied from the charger to the electric vehicle V is supplied from a commercial power source or a storage battery. Here, the charging station S includes a first power meter that measures the amount of power supplied from the commercial power source to the charger, and a second power meter that measures the amount of power supplied from the storage battery to the charger And shall be provided. When power is supplied from the commercial power source to the charger, the first watt-hour meter measures the amount of power supplied, and transmits power supply data indicating the measured value to the charging infrastructure device 130. Similarly, when power is supplied from the storage battery to the charger, the second watt-hour meter measures the amount of power supplied, and transmits power supply amount data indicating the measured value to the charging infrastructure device 130. . When the power supply amount data receiving unit 133 of the charging infrastructure apparatus 130 receives the power supply amount data transmitted from the first watt-hour meter or the second watt-hour meter (S105), the power amount indicated by the power supply amount data The data including the information of the measured value of and the information indicating the watt-hour meter that has performed the measurement is sent to the feed data transmission unit 134.

  When the feed data transmission unit 134 of the charging infrastructure apparatus 130 receives the data sent from the feed amount data reception unit 133, the feed data transmission unit 134 reads the information stored in the attribute information storage unit 135. For example, when the data received from the power supply amount data receiving unit 133 includes information indicating that the power meter that has performed the measurement of the power amount is the first power meter, the power supply data transmitting unit 134 , And reads the attribute information stored in association with the power source "commercial power source". Further, when the data received from the power supply amount data receiving unit 133 includes information indicating that the power meter that has performed the measurement of the power amount is the second power meter, the power supply data transmitting unit 134 , Read out the attribute information stored in association with the power supply "solar power generation system". Then, the power supply data transmission unit 134 includes the charging infrastructure ID, the information of the measured value of the power amount included in the data received from the power supply amount data reception unit 133, and the attribute information read from the attribute information storage unit 135. The included feed data is transmitted to the charging infrastructure information provision device 110 (S106).

  The charging infrastructure device 130 of each charging infrastructure S repeats the processing from step S101 to step S106 as described above each time power feeding to the electric vehicle V is performed in the charging infrastructure S.

  The power feeding data receiving unit 111 of the charging infrastructure information provision device 110 receives the power feeding data transmitted from the charging infrastructure device 130, each time based on the information included in the power feeding data, the charging infrastructure S performs the electric vehicle Information of the amount of power supplied to V and the attribute information of the power are associated with each other and stored in the power supply information storage unit 114 (S107). For example, when information such as charging infrastructure ID “Sa”, electric energy “10 (kW)”, and sunlight “100 (%)” is included in the feed data, the feed data receiving unit 111 receives the feed information storage unit. Among the information stored in 114, the value of each information stored in association with the charging infrastructure ID “Sa” is: nuclear power “0 (kW)”, thermal power “0 (kW)”, exhaustion Stores the values to which the other energy energy "0 (kW)", sunlight "10 (kW)", wind energy "0 (kW)", and other renewable energy "0 (kW)" are added. Thus, every time power feeding to the electric vehicle V is performed by the charging infrastructure S, information on the power amount of each attribute fed by the charging infrastructure S is integrated in the power feeding information storage unit 114. Will be stored.

  As described above, when the information stored in the power supply information storage unit 114 is updated, the contribution evaluation unit 112 of the charging infrastructure information provision device 110 determines each information based on the information stored in the power supply information storage unit 114. The contribution to the power supply of the predetermined | prescribed attribute in charge infrastructure S is evaluated (S108). In this example, the contribution evaluation unit 112 evaluates the contribution to the power supply generated by the power generation method using renewable energy. In the case of this example, the contribution evaluation unit 112 evaluates the absolute value of the sunlight (kW) associated with each charging infrastructure ID. Then, the contribution evaluation unit 112 sends data indicating the predetermined number of charging infrastructure IDs to the charging infrastructure information provision unit 113 in order from the one with the largest absolute value of sunlight (kW) as the evaluation result.

  Upon receiving the data sent from the contribution evaluation unit 112, the charge infrastructure information provision unit 113 of the charge infrastructure information provision device 110 reads the information stored in the charge infrastructure information storage unit 115. For example, the charging infrastructure information provision unit 113 reads out the charging infrastructure name and the address stored in association with each charging infrastructure ID indicated by the data received by the contribution evaluation unit 112. Then, the charging infrastructure information provision unit 113, for example, publishes each information read out to the WWW and provides the vehicle-mounted device 170 (S109).

  In this way, the on-board unit 170 can acquire information on the charging infrastructure S published by the charging infrastructure information provision device 110. Depending on this information, information on the charging infrastructure S that greatly contributes to the supply of power generated by solar power generation is preferentially introduced. Naturally, the charging infrastructure S introduced can be expected to increase customer attraction. Therefore, if the charge infrastructure S operator is asked to introduce its own charge infrastructure S to the user of the electric vehicle V, an attempt is made to actively supply power generated by solar power generation. It is speculated that the working mind will work.

  As described above, the charging infrastructure information provision system 100 can make the operator of the charging infrastructure S conscious of actively supplying power of a predetermined attribute to the electric vehicle V.
