Mode for Carrying Out the Invention

[0013] 〔Exemplary Embodiment 1〕 The first exemplary embodiment of the present invention will be described in detail with reference to the drawings. This exemplary embodiment is a basic form of the exemplary embodiments described later. Note that the reference numerals in the drawings appended to this overview are for convenience and are appended to each element as an example to assist understanding, and are not intended to limit the present invention to the illustrated aspects. Also, the connection lines between the blocks in the drawings and the like referred to in the following description include both bidirectional and unidirectional ones. The one-way arrows schematically show the flow of main signals (data) and do not exclude bidirectionality. Also, the connection points of the inputs and outputs of each block in the figure may be configured with ports or interfaces, but illustration of these configurations is omitted.

[0014] <Management Apparatus 1 According to Exemplary Embodiment 1> FIG. 1 is a diagram showing the configuration of a management device according to a first exemplary embodiment of the present invention together with exemplary charging facilities and electric vehicles. As shown in FIG. 1, the management device 1 according to this exemplary embodiment includes an acquisition unit 11, an extraction unit 12, and a transmission unit 13. The management device 1 can be configured by a server or the like installed on a cloud platform or the Internet. Further, the management device 1 may be a MEC (Multi-access Edge Computing or Mobile Edge Computing) server installed at a position close to the base station. The acquisition unit 11 is configured to realize an acquisition means in this exemplary embodiment. The extraction unit 12 is configured to realize an extraction means in this exemplary embodiment. The transmission unit 13 is configured to realize a transmission means in this exemplary embodiment.

[0015] The acquisition unit 11 acquires power state information indicating the power state in a target area TA including one or more charging facilities ES1 to ES3, and power amount information indicating the power amount of each of a plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA.

[0016] The target area TA is set to include one or more charging facilities ES1 to ES3. For example, a circular range with a radius of several kilometers centered on one charging facility may be set as the target area TA, or a circular range with a radius of several kilometers centered on an arbitrary point may be set as the target area TA. Further, the target area TA may be set to include a specific area.

[0017] The management device 1 can communicate with in-vehicle terminals mounted on electric vehicles EV1 to EV3 within the target area TA via a base station (not shown) installed inside the target area TA or in the vicinity outside the target area TA. For example, the base station may be a base station of a fifth-generation mobile communication system (5G) installed by a telecommunications carrier, or a base station of a network operated by a person other than a telecommunications carrier called local 5G. Further, the base station may be a base station of Wifi (registered trademark) or a fourth-generation mobile communication system (4G). Also, the communication service providing area in the target area TA may be composed of a plurality of cells.

[0018] The charging facilities ES1 to ES3 are charging facilities equipped with charging stands and can charge or discharge electric power to and from the electric vehicles EV1 to EV3. The electric vehicles EV1 to EV3 are vehicles such as electric cars, plug-in hybrid vehicles, turret trucks, electric microcars, electric two-wheelers, and Segways. Generally, an electric vehicle with insufficient electric power performs charging (buying electricity) at the charging facilities ES1 to ES3, and an electric vehicle with surplus electric power performs discharging (selling electricity) at the charging facilities ES1 to ES3.

[0019] As an example, the management device 1 is configured to be able to communicate with an energy management system using a smart grid via a network. Here, the specific configuration of the network does not limit this exemplary embodiment, but as an example, a wireless LAN (Local Area Network), a wired LAN, a WAN (Wide Area Network), a public line network, a mobile data communication network, or a combination of these networks can be used.

[0020] The acquisition unit 11 can acquire, for example, power state information indicating the power state of each of the charging facilities ES1 to ES3 from an energy management system. Further, the acquisition unit 11 may acquire power state information indicating the power state from each of the charging facilities ES1 to ES3 via the above-described network. The power state information of the charging facility is, for example, a value indicating the ratio of the current power supply amount that the charging facility can supply (the amount of power that the charging facility can store at present) when the maximum value of the power supply amount that the charging facility can supply (the amount of power that the charging facility can store) is set to 100%.

[0021] In addition, the acquisition unit 11 acquires power amount information indicating the power amount from each of the electric vehicles EV1 to EV3. Each of the in-vehicle terminals mounted on the electric vehicles EV1 to EV3 periodically transmits the power amount information indicating the power amount of the electric vehicles EV1 to EV3 to the management device 11. Further, each of the in-vehicle terminals may transmit the power amount information indicating the power amount of each of the electric vehicles EV1 to EV3 to the management device 11 when a request is made from the management device 1.

[0022] The extraction unit 12 extracts, based on the power amounts of the plurality of electric vehicles EV1 to EV3 indicated by the power amount information, the electric vehicles EV1 to EV3 corresponding to the power state of the target area among the plurality of electric vehicles EV1 to EV3.

[0023] For example, the extraction unit 12 refers to the power amount information of the electric vehicles EV1 to EV3, and for an electric vehicle with a surplus of power amount that can discharge to the charging facility, extracts the electric vehicle as an electric vehicle corresponding to the charging facility with a tight power state among the charging facilities ES1 to ES3. Further, the extraction unit 12 refers to the power amount information of the electric vehicles EV1 to EV3, and for a vehicle that has no surplus of power amount and needs to be charged from the charging facility, extracts the electric vehicle as an electric vehicle corresponding to the charging facility in a supply-excessive state with a surplus of power state among the charging facilities ES1 to ES3.

[0024] The transmitter 13 transmits information about the target area TA to at least one of the electric vehicles EV1 to EV3 extracted by the extractor 12. For example, the transmitter 13 transmits information about charging facilities ES1 to ES3 in the target area TA that are under power pressure to vehicles that have excess power and can discharge at charging facilities. The transmitter 13 also transmits information about charging facilities ES1 to ES3 in the target area TA that have excess power and are under power oversupply to vehicles that have no excess power and need to be charged from charging facilities.

[0025] (Effects of the management device according to the first exemplary embodiment) As described above, according to the management device 1 of this exemplary embodiment, the extraction unit 12 extracts electric vehicles EV1-EV3 from the plurality of electric vehicles EV1-EV3 that correspond to the power state of the target area based on the power amounts of each of the plurality of electric vehicles EV1-EV3 indicated by the power amount information. Therefore, for example, the transmission unit 13 transmits information about charging facilities ES1-ES3 in the target area TA that are under power pressure to electric vehicles that have excess power and can discharge to charging facilities. This allows electric vehicles with excess power to discharge (sell) to charging facilities that are under power pressure.

[0026] Furthermore, to vehicles that do not have a surplus in the amount of power and need to be charged from a charging facility, the transmitter 13 transmits information about charging facilities that have a surplus in the power state among the charging facilities ES1 to ES3 in the target area TA. This allows electric vehicles that do not have a surplus in the amount of power to be charged (purchased electricity) from charging facilities that have a surplus in the power state.

[0027] <Management Method According to Exemplary Embodiment 1> Figure 2 is a flowchart showing the flow of the management method according to the first exemplary embodiment of the present invention. As shown in Figure 2, the management method S1 includes steps S11 to S13. First, the acquisition unit 11 acquires power state information indicating the power state in the target area TA including one or more charging facilities ES1 to ES3, and power amount information indicating the power amount of each of a plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA (S11).

[0028] Next, the extraction unit 12 extracts, based on the power amount of each of the plurality of electric vehicles EV1 to EV3 indicated by the power amount information, the electric vehicles EV1 to EV3 among the plurality of electric vehicles EV1 to EV3 that correspond to the power state of the target area TA (S12).

[0029] Finally, the transmission unit 13 transmits information regarding the target area TA to at least any one of the extracted electric vehicles EV1 to EV3 (S13). For example, the transmission unit 13 transmits information regarding the charging facilities in the target area TA that are in a tight power state among the charging facilities ES1 to ES3 to the vehicles that have a surplus of power amount and can discharge to the charging facilities. Also, the transmission unit 13 transmits information regarding the charging facilities in a surplus supply state with a power state margin among the charging facilities ES1 to ES3 in the target area TA to the vehicles that do not have a surplus of power amount and need to be charged from the charging facilities.

[0030] (Effect of the management method according to Exemplary Embodiment 1) As described above, according to the management method according to this exemplary embodiment, for example, the transmission unit 13 transmits information regarding the charging facilities in the target area TA that are in a tight power state among the charging facilities ES1 to ES3 to the electric vehicles that have a surplus of power amount and can discharge to the charging facilities. As a result, the electric vehicles with a surplus of power amount can discharge (sell electricity) to the charging facilities in a tight power state.

[0031] In addition, for a vehicle that does not have enough power and needs to be charged from a charging facility, the transmission unit 13 transmits information about a charging facility in a supply surplus state with a power margin among the charging facilities ES1 to ES3 in the target area TA. As a result, an electric vehicle without enough power can charge (purchase electricity) from a charging facility with a power margin.

[0032] <Management system 100 according to Exemplary Embodiment 1> As shown in FIG. 3, the management system 100 according to this exemplary embodiment includes an acquisition unit 11, an extraction unit 12, and a transmission unit 13. The acquisition unit 11, the extraction unit 12, and the transmission unit 13 are communicably configured via a network N as an example. Here, the specific configuration of the network N does not limit this exemplary embodiment, but as an example, a wireless LAN, a wired LAN, a WAN, a public line network, a mobile data communication network, or a combination of these networks can be used.

[0033] The acquisition unit 11 acquires power state information indicating the power state in a target area TA including one or more charging facilities ES1 to ES3, and power amount information indicating the power amount of each of a plurality of electric vehicles EV1 to EV3 that can be charged and discharged in the target area TA.

[0034] The acquisition unit 11 can acquire, for example, power state information indicating the power state of each of the charging facilities ES1 to ES3 from an energy management system. Also, the acquisition unit 11 may acquire power state information indicating the power state from each of the charging facilities ES1 to ES3 via the above-described network. Further, the acquisition unit 11 acquires power amount information indicating the power amount from each of the electric vehicles EV1 to EV3.

[0035] The extraction unit 12 extracts electric vehicles EV1 to EV3 corresponding to the power state of the target area among the plurality of electric vehicles EV1 to EV3 based on the power amount of each of the plurality of electric vehicles EV1 to EV3 indicated by the power amount information.

[0036] The transmitting means 13 transmits information regarding the target area TA to at least any one of the electric vehicles EV1 to EV3 extracted by the extracting means 12. For example, the transmitting means 13 transmits information regarding a charging facility in a tight power state among the charging facilities ES1 to ES3 in the target area TA to an electric vehicle that has a surplus of electric power and can discharge to the charging facility. Further, the transmitting means 13 transmits information regarding a charging facility in a supply surplus state with a power state margin among the charging facilities ES1 to ES3 in the target area TA to an electric vehicle that has no surplus of electric power and needs to be charged from the charging facility.

[0037] (Effect by the management system according to Exemplary Embodiment 1) As described above, according to the management system 100 according to this exemplary embodiment, for example, the transmitting means 13 transmits information regarding a charging facility in a tight power state among the charging facilities ES1 to ES3 in the target area TA to an electric vehicle that has a surplus of electric power and can discharge to the charging facility. Thereby, an electric vehicle with a surplus of electric power can discharge (sell electricity) to a charging facility in a tight power state.

[0038] Further, the transmitting means 13 transmits information regarding a charging facility in a supply surplus state with a power state margin among the charging facilities ES1 to ES3 in the target area TA to a vehicle that has no surplus of electric power and needs to be charged from the charging facility. Thereby, an electric vehicle with no surplus of electric power can charge (buy electricity) from a charging facility with a power state margin.

[0039] [Exemplary Embodiment 2] The second exemplary embodiment of the present invention will be described in detail with reference to the drawings. Note that components having the same functions as those described in Exemplary Embodiment 1 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0040] <Information processing apparatus 1A according to Exemplary Embodiment 2> 4 is a diagram showing the configuration of an information processing device 1A according to a second exemplary embodiment of the present invention, together with exemplary charging equipment and an electric vehicle. As shown in FIG. 4, the information processing device 1A according to this exemplary embodiment includes a control unit 10A, a storage unit 20A, and a communication unit 40A.

[0041] The communication unit 40A can communicate with the onboard terminals mounted on the electric vehicles EV1-EV3 and the charging facilities ES1-ES3 within the target area TA via base stations (not shown) installed within the target area TA or in the vicinity outside the target area TA. For example, the base stations may be base stations of a fifth-generation mobile communication system (5G) installed by a telecommunications carrier, or may be base stations of a network operated by a party other than a telecommunications carrier, known as local 5G. The base stations may also be base stations of Wifi (registered trademark) or a fourth-generation mobile communication system (4G). The area providing communication services in the target area TA may be composed of multiple cells.

[0042] The control unit 10A includes an acquisition unit 11, an extraction unit 12, a transmission unit 13, and a transmission information generation unit 14. Note that components having the same functions as those described in the first exemplary embodiment are denoted by the same reference numerals, and their description will be omitted as appropriate.

[0043] The acquisition unit 11 acquires, via the communication unit 40A, power status information indicating the power status in a target area TA including one or more charging facilities ES1 to ES3, and power amount information indicating the amount of power of each of multiple electric vehicles EV1 to EV3 that can be charged or discharged within the target area TA.

[0044] The extraction unit 12 extracts, from the plurality of electric vehicles EV1 to EV3, electric vehicles EV1 to EV3 that correspond to the power state of the target area, based on the amount of power of each of the plurality of electric vehicles EV1 to EV3 indicated by the power amount information.

[0045] The transmission information generation unit 14 generates information about the target area TA from power status information indicating the power status of one or more charging facilities ES1 to ES3 included in the target area TA, power amount information indicating the amount of power of each of multiple electric vehicles EV1 to EV3 that can be charged or discharged within the target area TA, etc.

[0046] The storage unit 20A is configured by a RAM (Random Access Memory) equipped with a battery, a flash memory which is a nonvolatile memory, a hard disk, etc. It is preferable that the storage unit 20A retains information when the power supply of the information processing device 1A is turned off, but this information may be stored on a hard disk or the like of the information processing device 1A and transferred from the hard disk or the like to the storage unit 20A configured by a volatile RAM when the information processing device 1A is started up.

[0047] The storage unit 20A stores power status information EPSI, charging facility location information EPPI, selling and buying price information PRI, power quantity information EPQI, and electric vehicle location information EVPI. The power status information EPSI is information that indicates the power status of each of one or more charging facilities ES1 to ES3 included in the target area TA.

[0048] Fig. 5 is a diagram showing an example of power status information EPSI, charging facility location information EPPI, and selling / buying price information PRI stored in storage unit 20A of information processing device 1A. Fig. 6 is a diagram showing an example of power quantity information EPQI and electric vehicle location information EVPI stored in storage unit 20A of information processing device 1A. Note that the charging facilities with charging facility IDs "001" to "003" correspond to charging facilities ES1 to ES3, respectively. Also, the electric vehicles with electric vehicle IDs "00001" to "00003" correspond to electric vehicles EV1 to EV3, respectively.

[0049] As shown in the upper diagram of FIG. 5, for example, the power state information EPSI of each of the charging facilities with charging facility IDs from "001" to "003" indicates that they are "92%", "64%", and "72%". The acquisition unit 11 appropriately receives, via the communication unit 40A, the power state information indicating the power state of each of the charging facilities ES1 to ES3 from the energy management system, and updates the power state information EPSI stored in the storage unit 20A. Further, the acquisition unit 11 may appropriately receive, via the communication unit 40A, the power state information indicating the power state from each of the charging facilities ES1 to ES3, and update the power state information EPSI stored in the storage unit 20A.

[0050] The charging facility position information EPPI is information indicating the position of each of the one or more charging facilities ES1 to ES3 included in the target area TA. As shown in the middle diagram of FIG. 5, for example, the position information EPPI of each of the charging facilities with charging facility IDs from "001" to "003" indicates that they are "XXXX", "YYYY", and "ZZZZ". Since the charging facility position information EPPI stored in the storage unit 20A is fixed, it is assumed to be pre-registered. In the case of new installation or abolition of a charging facility, the charging facility position information EPPI stored in the storage unit 20A is appropriately added or deleted.

[0051] The selling and buying price information PRI is information indicating the selling price and buying price of the power of each of the one or more charging facilities ES1 to ES3 included in the target area TA. As shown in the lower diagram of FIG. 5, for example, the selling and buying price information PRI of each of the charging facilities with charging facility IDs from "001" to "003" indicates that they are "Selling price: aaa yen, Buying price: bbb yen", "Selling price: ccc yen, Buying price: ddd yen", and "Selling price: eee yen, Buying price: fff yen". The acquisition unit 11 appropriately receives, via the communication unit 40A, the selling and buying price information PRI from each of the charging facilities ES1 to ES3, and updates the selling and buying price information PRI stored in the storage unit 20A.

[0052] The amount-of-power information EPQI is information indicating the amount of power of each of a plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA. As shown in the upper diagram of FIG. 6, for example, it shows that the amount-of-power information EPQI of each of the electric vehicles with electric vehicle IDs "00001" to "00003" is "60%", "20%", and "90%". The acquisition unit 11 appropriately receives, via the communication unit 40A, the amount-of-power information indicating the amount of power from each of the electric vehicles EV1 to EV3, and updates the amount-of-power information EPQI stored in the storage unit 20A.

[0053] The electric vehicle position information EVPI is information indicating the position of each of a plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA. As shown in the lower diagram of FIG. 6, for example, it shows that the electric vehicle position information EVPI of each of the electric vehicles with electric vehicle IDs "00001" to "00003" is "xxxx", "yyyy", and "zzzz". The acquisition unit 11 appropriately receives, via the communication unit 40A, the electric vehicle position information indicating the position of the electric vehicle from each of the electric vehicles EV1 to EV3, and updates the electric vehicle position information EVPI stored in the storage unit 20A.

[0054] Here, the electric vehicle position information of each of the electric vehicles EV1 to EV3 can be obtained, as an example, by a GPS (Global Positioning System) device mounted on each of the electric vehicles EV1 to EV3. The electric vehicles EV1 to EV3 appropriately transmit the electric vehicle position information obtained by the GPS device to the information processing device 1A.

[0055] (When the power state of the charging facility indicates an excess supply of power) When the power state of the charging facility indicates an excess supply of power, the extraction unit 12 extracts, from among the plurality of electric vehicles EV1 to EV3, the electric vehicles whose amount of power is equal to or less than a first threshold value. For example, the first threshold value is a value of about 20%, but is not particularly limited to this value.

[0056] For example, the extraction unit 12 refers to the power quantity information EPQI of electric vehicles EV1 to EV3 shown in the upper diagram of Fig. 6, and extracts electric vehicle EV2, whose power quantity information EPQI is "20%", as an electric vehicle that has no excess power and needs to be charged from a charging facility. Furthermore, the extraction unit 12 refers to the power status information EPSI shown in the upper diagram of Fig. 5, and extracts charging facility ES1, whose power status is relatively high at "92%", as a charging facility whose power status indicates an oversupply of power.

[0057] The transmission information generating unit 14 generates, as information on the target area TA, information on the charging facility ES1 extracted by the extracting unit 12 as the charging facility whose power state indicates an excess supply of power.

[0058] The information related to the target area TA includes location information of one or more charging facilities ES1 to ES3 in the target area TA. The transmission information generation unit 14 includes the location information of the charging facility ES1 as the transmission information extracted by the extraction unit 12 and to be transmitted to the electric vehicle EV2. The transmission unit 13 transmits the location information of the charging facility ES1 to the electric vehicle EV2 via the communication unit 40A.

[0059] Furthermore, the information about the target area may include information about at least one of the selling and buying prices of electricity at each of one or more charging facilities ES1 to ES3 in the target area TA. For example, the transmission information generation unit 14 includes the selling and buying price information PRI of the charging facility ES1 as the transmission information to be transmitted to the electric vehicle EV2, which is extracted by the extraction unit 12. The transmission unit 13 transmits the selling and buying price information of the charging facility ES1 to the electric vehicle EV2 via the communication unit 40A.

[0060] In addition, the information regarding the target area may include information recommending charging at one or more charging facilities ES1 to ES3 in the target area TA. For example, the transmission information generation unit 14 includes, as transmission information to be transmitted to the electric vehicle EV2 extracted by the extraction unit 12, information recommending charging at the charging facility ES1. The transmission unit 13 transmits, via the communication unit 40A, information recommending charging at the charging facility ES1 to the electric vehicle EV2.

[0061] FIG. 7 is a diagram showing an example of information regarding the target area. For example, the electric vehicles EV1 to EV3 are equipped with a car navigation system, and it is possible to display route information and recommendation information together with map information on this car navigation system. The upper diagram in FIG. 7 shows an example of the display screen of the display device of the car navigation system, and displays route information MI to the charging facility ES1 and recommendation information RI recommending charging at the charging facility ES1 for the electric vehicle EV2. Further, the display device displays the electricity purchase price “bbb yen” at the charging facility ES1 as the recommendation information RI.

[0062] (When the power state of the charging facility indicates a power shortage) When the power state of the charging facility indicates a power shortage, the extraction unit 12 extracts electric vehicles among the plurality of electric vehicles EV1 to EV3 whose power amount is equal to or greater than a second threshold value. For example, the second threshold value is about 80%, but is not particularly limited to this value.

[0063] For example, the extraction unit 12 refers to the power amount information EPQI of the electric vehicles EV1 to EV3 shown in the upper diagram of FIG. 6, and extracts the electric vehicle EV3 whose power amount information EPQI is “90%” as an electric vehicle with a surplus power amount and capable of discharging to the charging facility. Further, the extraction unit 12 refers to the power state information EPSI shown in the upper diagram of FIG. 5, and extracts the charging facility of the charging facility ES2 with a relatively low power state of “64%” as a charging facility whose power state indicates a power shortage.

[0064] The transmission information generation unit 14 generates information regarding the charging facility ES2 extracted as a charging facility indicating a power shortage in power state by the extraction unit 12, as information regarding the target area TA.

[0065] The transmission information generation unit 14 includes the position information of the charging facility ES2 as transmission information to be transmitted to the electric vehicle EV3, extracted by the extraction unit 12. The transmission unit 13 transmits the position information of the charging facility ES2 to the electric vehicle EV3 via the communication unit 40A.

[0066] Also, the transmission information generation unit 14 includes the selling and buying price information PRI of the charging facility ES2 as transmission information to be transmitted to the electric vehicle EV3, extracted by the extraction unit 12. The transmission unit 13 transmits the selling and buying price information of the charging facility ES2 to the electric vehicle EV3 via the communication unit 40A.

[0067] Also, the information regarding the target area may include information recommending discharging at one or more charging facilities ES1 to ES3 in the target area. For example, the transmission information generation unit 14 includes information recommending discharging at the charging facility ES2 as transmission information to be transmitted to the electric vehicle EV3, extracted by the extraction unit 12. The transmission unit 13 transmits information recommending discharging at the charging facility ES2 to the electric vehicle EV3 via the communication unit 40A.

For example, the display device of the car navigation system mounted on the electric vehicles EV1 to EV3 can display the route information to the charging facility, and the convenience of the user can be improved.

[0070] Further, the transmission unit 13 transmits, as information regarding the target area TA, including information regarding at least one of the selling price and the buying price of power at each of one or a plurality of charging facilities ES1 to ES3 in the target area TA. For example, the display device of the car navigation system mounted on the electric vehicles EV1 to EV3 can display at least one of the selling price and the buying price of power at the charging facility, and can provide a basis for the user to judge whether to sell or buy electricity.

[0071] Further, when the power state of the charging facility indicates an excess supply of power, the extraction unit 12 extracts electric vehicles among the plurality of electric vehicles EV1 to EV3 whose power amount is equal to or less than the first threshold value. Therefore, it is possible to easily extract the electric vehicle corresponding to the power state of the charging facility.

[0072] Further, the transmission unit 13 transmits, as information regarding the target area TA, including information indicating that charging is recommended at one or a plurality of charging facilities ES1 to ES3 in the target area TA.

[0075] 〔Exemplary Embodiment 3〕 A third exemplary embodiment of the present invention will be described in detail with reference to the drawings. Components having the same functions as those described in the first and second exemplary embodiments are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0076] <Information Processing Apparatus 1B According to Exemplary Embodiment 3> FIG. 8 is a diagram showing the configuration of an information processing apparatus 1B according to the third exemplary embodiment of the present invention together with exemplary charging facilities and electric vehicles. As shown in FIG. 8, the information processing apparatus 1B according to this exemplary embodiment includes a control unit 10B, a storage unit 20A, and a communication unit 40A.

[0077] The control unit 10B includes an acquisition unit 11, an extraction unit 12B, a transmission unit 13, and a transmission information generation unit 14. Components having the same functions as those described in the first and second exemplary embodiments are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0078] The acquisition unit 11 acquires, via the communication unit 40A, power state information indicating the power state in a target area TA including one or a plurality of charging facilities ES1 to ES3, and power amount information indicating the power amount of each of a plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA.

[0079] The extraction unit 12B extracts, based on the power amount of each of the plurality of electric vehicles EV1 to EV3 indicated by the power amount information, the electric vehicles EV1 to EV3 among the plurality of electric vehicles EV1 to EV3 that correspond to the power state of the target area.

[0080] The extraction unit 12B includes a priority assignment unit 121. When the extraction unit 12B extracts a plurality of electric vehicles EV1 to EV3, the priority assignment unit 121 assigns priorities to the plurality of extracted electric vehicles EV1 to EV3.

[0081] FIG. 9 is a diagram showing an example of the priorities assigned by the priority assignment unit 121. The priority assignment unit 121 of the extraction unit 12B assigns priorities to each of the plurality of electric vehicles EV1 to EV3 according to the amount of electricity of each of the plurality of electric vehicles EV1 to EV3. For example, assume that the extraction unit 12B refers to the electricity amount information EPQI of the electric vehicles EV1 to EV3 shown in the upper diagram of FIG. 6 and extracts the electric vehicles that need to be charged from the charging facility without sufficient margin in the electricity amount. In this case, as shown in the upper diagram of FIG. 9, the priority assignment unit 121 assigns higher priorities in ascending order of the amount of electricity. In the upper diagram of FIG. 9, the highest priority "1" is assigned to the electric vehicle EV2 with the least amount of electricity, and the priorities "2" and "3" are assigned to the electric vehicles EV1 and EV3 in this order.

[0082] Conversely, assume that the extraction unit 12B extracts the electric vehicles with sufficient margin in the electricity amount and capable of discharging to the charging facility. In this case, the priority assignment unit 121 will assign higher priorities in descending order of the amount of electricity.

[0083] The transmission information generation unit 14 generates information regarding the charging facility ES1 extracted as the charging facility indicating excessive power supply in the power state by the extraction unit 12B as information regarding the target area TA.

[0084] The transmission unit 13 transmits information regarding the target area TA to the electric vehicles with relatively high priorities. For example, assume that it is set to transmit information regarding the target area TA to two electric vehicles with relatively high priorities. In this case, the transmission unit 13 refers to the priorities shown in the upper diagram of FIG. 9 and transmits information regarding the target area TA to the two electric vehicles EV1 and EV2 with relatively high priorities.

[0085] Further, the priority assignment unit 121 of the extraction unit 12B may assign relatively high priorities to one or more electric vehicles among a plurality of electric vehicles that are relatively close to at least any one of the plurality of charging facilities ES1 to ES3. For example, as shown in the lower diagram of FIG. 9, the priority assignment unit 121 assigns priorities according to the distances from the electric vehicles EV1 to EV3 to the nearest power receiving facility. In the lower diagram of FIG. 9, the highest priority "1" is assigned to the electric vehicle EV3 with the smallest distance to the nearest charging facility, and the priorities "2" and "3" are assigned to the electric vehicles EV1 and EV2 in this order.

[0086] For example, it is assumed that information regarding the target area TA is set to be transmitted to two electric vehicles with relatively high priorities. In this case, the transmission unit 13 refers to the priorities shown in the lower diagram of FIG. 9 and transmits information regarding the target area TA to the two electric vehicles EV3 and EV1 with relatively high priorities.

[0087] (Effect by the information processing apparatus 1B according to the exemplary embodiment 3) As described above, according to the information processing apparatus 1B according to the present exemplary embodiment, when the extraction unit 12B extracts a plurality of electric vehicles EV1 to EV3, the priority assignment unit 121 assigns priorities to the extracted plurality of electric vehicles EV1 to EV3. As a result, the transmission unit 13 can transmit information regarding the target area TA to the electric vehicle with a relatively high priority, and can transmit the information to the user who has a relatively high need for the information regarding the target area TA.

[0088] In addition, since the priority assignment unit 121 of the extraction unit 12B assigns priorities to each of the plurality of electric vehicles EV1 to EV3 according to the amount of electricity of each of the plurality of electric vehicles EV1 to EV3, for example, it is possible to increase the priority of an electric vehicle that has no margin in the amount of electricity and needs to be charged from a charging facility. Conversely, the priority assignment unit 121 can also increase the priority of an electric vehicle that has a margin in the amount of electricity and can discharge to a charging facility.

[0089] Further, the priority assignment unit 121 of the extraction unit 12B assigns a relatively high priority to an electric vehicle among the plurality of electric vehicles EV1 to EV3 that is relatively close to at least one of the plurality of charging facilities ES1 to ES3. Therefore, the transmission unit 13 can preferentially transmit information regarding the target area TA to the electric vehicle close to the charging facility.

[0090] 〔Exemplary Embodiment 4〕 A fourth exemplary embodiment of the present invention will be described in detail with reference to the drawings. Components having the same functions as those described in the first to third exemplary embodiments are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0091] <Information Processing Apparatus 1C According to Exemplary Embodiment 4> FIG. 10 is a diagram showing the configuration of an information processing apparatus 1C according to a fourth exemplary embodiment of the present invention together with exemplary charging facilities and electric vehicles. As shown in FIG. 10, the information processing apparatus 1C according to this exemplary embodiment includes a control unit 10C, a storage unit 20A, and a communication unit 40A.

[0092] The control unit 10C includes an acquisition unit 11, an extraction unit 12B, a transmission unit 13, a transmission information generation unit 14, and a determination unit 15. Components having the same functions as those described in the first to third exemplary embodiments are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0093] The acquisition unit 11 acquires, via the communication unit 40A, power state information indicating the power state in a target area TA including one or more charging facilities ES1 to ES3, and power amount information indicating the power amount of each of the plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA.

[0094] The extraction unit 12B extracts the electric vehicles EV1 to EV3 corresponding to the power state of the target area among the plurality of electric vehicles EV1 to EV3 based on the power amount of each of the plurality of electric vehicles EV1 to EV3 indicated by the power amount information. When the extraction unit 12B extracts a plurality of electric vehicles EV1 to EV3, the priority assignment unit 121 assigns priorities to the extracted plurality of electric vehicles EV1 to EV3.

[0095] The transmission information generation unit 14 generates information related to the target area TA from the power state information indicating the power states of the one or more charging facilities ES1 to ES3 included in the target area TA, the power amount information indicating the power amount of each of the plurality of electric vehicles EV1 to EV3 that can be charged and discharged within the target area TA, and the like. The transmission unit 13 transmits the information related to the target area TA generated by the transmission information generation unit 14 to the electric vehicle with a relatively high priority.

[0096] The determination unit 15 determines whether any of the plurality of electric vehicles EV1 to EV3 has performed charging or discharging. More specifically, the determination unit 15 refers to the position information regarding each of the plurality of electric vehicles EV1 to EV3 and the position information of the one or more charging facilities ES1 to ES3 in the target area TA, and determines whether any of the plurality of electric vehicles EV1 to EV3 has performed charging or discharging.

[0097] For example, the determination unit 15 acquires the electric vehicle position information EVPI of the electric vehicle EV2 for which charging was recommended shown in the upper figure of FIG. 7 and the charging facility position information EPPI of the recommended charging facility ES1 from the storage unit 20A. Then, when the electric vehicle EV2 stays at the charging facility ES1 for a predetermined time or more, the determination unit 15 determines that the electric vehicle EV2 has performed charging at the charging facility ES1. In addition, even when the electric vehicle EV2 stays at a charging facility that is not recommended for a predetermined time or more, it may be determined that the electric vehicle EV2 has performed charging at that charging facility.

[0098] Similarly, the determination unit 15 acquires, from the storage unit 20A, electric vehicle position information EVPI of the electric vehicle EV3 recommended to discharge and charging facility position information EPPI of the recommended charging facility ES2, as shown in the lower diagram of Fig. 7. Then, when the electric vehicle EV3 remains at the charging facility ES2 for a predetermined time or longer, the determination unit 15 determines that the electric vehicle EV3 has discharged at the charging facility ES1.

[0099] The transmitter 13 transmits information about the target area TA to electric vehicles with a relatively low priority, depending on the determination result by the determiner 15. If an electric vehicle with a relatively high priority that has received information about the target area TA purchases or sells electricity, the priority of that electric vehicle becomes low. Therefore, the transmitter 13 transmits information about the target area TA to electric vehicles with a relatively low priority, excluding that electric vehicle.

[0100] Furthermore, the determination unit 15 may refer to information acquired from at least one of the electric vehicles EV1-EV3 indicating that charging or discharging has been performed, and determine whether the electric vehicle has performed charging or discharging. In this case, the on-board terminal mounted on each of the electric vehicles EV1-EV3 transmits information indicating that charging or discharging has been performed to the information processing device 1C when charging or discharging is completed. Then, when the information processing device 1C receives the information indicating that charging or discharging has been performed via the communication unit 40A, the determination unit 15 determines that the electric vehicle has performed charging or discharging.

[0101] (Effects of the information processing device 1C according to the fourth exemplary embodiment) As described above, according to the information processing device 1C according to this exemplary embodiment, the transmitter 13 transmits information about the target area TA even to electric vehicles with a relatively low priority, in accordance with the determination result by the determiner 15. Therefore, when an electric vehicle with a relatively high priority that has received information about the target area TA purchases or sells electricity, the transmitter 13 can transmit information about the target area TA to electric vehicles with a relatively low priority, excluding that electric vehicle.

[0102] Further, the determination unit 15 refers to the position information regarding each of the plurality of electric vehicles EV1 to EV3 and the position information of one or more charging facilities ES1 to ES3 in the target area TA, and determines that any one of the plurality of electric vehicles EV1 to EV3 has performed charging and discharging. Therefore, the determination unit 15 can easily determine that any one of the plurality of electric vehicles EV1 to EV3 has performed charging and discharging.

[0103] Also, the determination unit 15 refers to the information indicating that charging and discharging has been performed, which is acquired from at least any one of the plurality of electric vehicles EV1 to EV3, and determines that the electric vehicle has performed charging and discharging. Therefore, the determination unit 15 can easily determine that any one of the plurality of electric vehicles EV1 to EV3 has performed charging and discharging.
