[0040] The second display unit 23 is a liquid crystal panel, an organic EL panel, etc. The second display unit 23 can display a rescue request acquired from the server 30, as will be described later.

[0041] The second storage unit 24 stores vehicle information of the power supply vehicle 120 registered in advance by the power supply user in order to receive the service provided by the information processing system 1, registration information of the power supply user, and payment information for the power supply user to pay the usage fee for the service. The vehicle information is information related to the vehicle, and includes, for example, information indicating performance, a vehicle ID for identifying the power supply vehicle 120, etc.

[0042] The power supply vehicle 120 of the information processing system 1 is a vehicle that can supply power to the power receiving vehicle 110 of the power receiving user, and is the above-mentioned electric vehicle in which the power supply user rides.

[0046] The power supply device 123 is a device for charging the power receiving battery 114 mounted on the power receiving vehicle 110 by supplying power from a power supply battery 124 mounted on the power supply vehicle 120 to the power receiving vehicle 110. The power supply device 123 may be a device of either a contact power supply type or a contactless power supply type.

[0047] The power supply vehicle 120 may be able to become the power receiving vehicle 110 when the power supply battery 124 runs out of power. For this reason, the power supply vehicle 120 may be equipped with the power receiver 113. If the power supply user is set to receive only power supply service, the power supply vehicle 120 may not be equipped with the power receiver 113. In this embodiment, running out of power means that the battery installed in the vehicle has no remaining capacity, or that the vehicle cannot travel to the EV charging facility E even though the battery has remaining capacity.

[0048] The power supply battery 124 is a secondary battery such as a nickel-metal hydride battery or a lithium-ion battery. The power supply battery 124 is a battery that is mounted on the power supply vehicle 120 and supplies power to an electric motor configured to drive the power supply vehicle 120, and to on-board equipment. In this embodiment, the batteries for driving the electric motor and the like and the batteries for auxiliary equipment such as on-board equipment are collectively referred to as power supply batteries 124. The power supply battery 124 is an example of a battery.

The second battery remaining capacity calculation unit 125 monitors the remaining capacity for supplying power to the electric motor at predetermined intervals. The second battery remaining capacity calculation unit 125 is an example of a remaining capacity calculation unit.

[0051] The external battery 130 is a battery mounted on the power supply vehicle 120 in order to charge the power receiving battery 114 of the power receiving vehicle 110. The external battery 130 is configured to adjust power so that the power receiving battery 114 of the power receiving vehicle 110 can be charged.

[0052] The external battery 130 includes a battery cell 131 , an external battery remaining capacity calculation unit 132 , and a power supply unit 133 .

[0053] The battery cell 131 is configured to charge the power receiving battery 114 of the power receiving vehicle 110 and to supply power to the electric motor that is the drive source of the power supply vehicle 120. The battery cell 131 is an example of a battery.

[0054] The external battery remaining capacity calculation unit 132 can calculate the remaining capacity in the battery cell 131. The external battery remaining capacity calculation unit 132 monitors the remaining capacity in the battery cell 131 at predetermined intervals. The external battery remaining capacity calculation unit 132 is an example of a remaining capacity calculation unit.

[0055] The power feeder 133 is a device for charging the power receiving battery 114 mounted on the power receiving vehicle 110 by supplying power from the battery cells 131 of the external battery 130 mounted on the power supply vehicle 120 to the power receiving vehicle 110. The power feeder 133 may be a device of either a contact power feeding type or a contactless power feeding type.

[0056] In the service of the information processing system 1, the power receiving user and the power supply user can be interchangeable. For example, when the power receiving battery 114 of the power receiving vehicle 110 of the power receiving user is charged at an EV charging facility E or the like, the power receiving vehicle 110 may be switched to the power supplying vehicle 120 (the power receiving user becomes the power supplying user). Furthermore, when the power supplying battery 124 of the power supplying vehicle 120 of the power supplying user runs out of power, the power supplying vehicle 120 may be switched to the power receiving vehicle 110 (the power supplying user becomes the power receiving user).

[0057] Here, the server 30 will be described.

[0058] The server 30 includes a wireless communication unit 31 , a distance calculation unit 32 , a required charge amount calculation unit 33 , a list creation unit 34 , a third storage unit 35 , a map information acquisition unit 36 ​​, and a processing unit 37 .

[0059] The wireless communication unit 31 is a communication interface capable of wireless communication, and is connected to a communication network such as the Internet or a communication line. The wireless communication unit 31 is capable of communicating with each of the first information terminal 10, the second information terminal 20, the power receiving vehicle 110, and the power supply vehicle 120 via the communication network. The wireless communication unit 31 is an example of an acquisition unit and a communication unit.

[0060] The distance calculation unit 32 acquires the position of the power receiving vehicle 110 from the wireless communication unit 31 and the positions of EV charging facilities E present in the vicinity of the power receiving vehicle 110 from the third memory unit 35 or the map information acquisition unit 36, and calculates the distance between the acquired power receiving vehicle 110 and the EV charging facilities E present in the vicinity of the power receiving vehicle 110. The distance is the distance on the route traveled by the power receiving vehicle 110.

[0061] The required charge amount calculation unit 33 calculates the amount of power required when the power receiving vehicle 110 travels the distance calculated by the distance calculation unit 32 .

[0062] The list creation unit 34 searches for a power supply vehicle 120 that can supply power to the power receiving vehicle 110 equivalent to the required amount of power calculated by the required charge amount calculation unit 33, and outputs the search result. Specifically, the list creation unit 34 searches for a power supply vehicle 120 that can supply power to the power receiving vehicle 110, creates a rescue list that is a result of the search for the power supply vehicles 120, and outputs the created rescue list to the first information terminal 10 via the wireless communication unit 31. The rescue list includes the time required for the power supply vehicle 120 to arrive at the vehicle, the fee to be paid to the power supply vehicle 120, etc. Furthermore, the rescue list may include characteristics for identifying the power supply vehicle 120 so that the power receiving user of the power receiving vehicle 110 can recognize that it is the power supply vehicle 120. This allows the power receiving user to recognize the rescue list via the first information terminal 10 and select a desired power supply vehicle 120 (power supply user) from the rescue list. The list creation unit 34 is an example of an output unit.

[0063] The third storage unit 35 stores map information and information included in the map information that indicates the location of the EV charging facility E. The map information may be information indicating a map for each country or information indicating a map of the entire world. The third storage unit 35 may also store vehicle information for the power receiving vehicle 110, vehicle information for the power supply vehicle 120, registration information for the power receiving user, registration information for the power supply user, payment information for the power receiving user, payment information for the power supply user, etc.

[0064] The map information acquisition unit 36 ​​acquires a map from an external map information server at predetermined intervals. When a rescue request is received from the power receiving vehicle 110, the map information acquisition unit 36 ​​may acquire a map of the power receiving vehicle 110 and the power supply vehicle 120 and their surroundings based on the location information of the first information terminal 10 acquired from the first information terminal 10 and the location information of the second information terminal 20 acquired from the second information terminal 20. The map information acquisition unit 36 ​​stores the acquired map in the third storage unit 35.

[0065] The processing unit 37 causes the map information acquisition unit 36 ​​to display, for example, the position of the power receiving vehicle 110 and the position of the power supply vehicle 120 (the power supply vehicle 120 selected by the power receiving user) that will rescue the power receiving vehicle 110 on the acquired map, and outputs the information to the second information terminal 20 of the power receiving vehicle 110 via the wireless communication unit 31.

[0066] Furthermore, the processing unit 37 calculates a travel time based on the distance from the power receiving vehicle 110 to the power supply vehicle 120 and an amount to be paid to the power supply vehicle 120, and outputs the calculated travel time and amount to the power supply vehicle 120 via the wireless communication unit 31. This allows the power supply user aboard the power supply vehicle 120 to understand the travel time and the amount to be received. Therefore, the power supply user can also select whether to head to the power receiving vehicle 110 to rescue the power receiving vehicle 110 (to supply power to the power supply vehicle 120). The distance from the power receiving vehicle 110 to the power supply vehicle 120 is the distance on the route that the power receiving vehicle 110 travels.

[0067] <Operation> Next, the information processing system 1, the information processing method, and the operation based on the program functions will be described with reference to FIGS.

[0068] FIG. 3 is a sequence diagram showing the operation of the information processing system 1 according to the embodiment. FIG. 4 is a block diagram showing how a power receiving user and a power supplying user perform advance usage registration. FIG. 5 is a block diagram showing how the first information terminal 10 and the power receiving vehicle 110 transmit location information to the server 30. FIG. 6 is a block diagram showing how the distance to the EV charging facility E and the required amount of power are calculated. FIG. 7 is a block diagram showing how a rescue request is made to the second information terminal 20 of the power supplying user when searching for the power supplying vehicle 120. FIG. 8 is a block diagram showing how a rescue list is created. FIG. 9 is a block diagram showing how a match is notified. FIG. 10 is a block diagram showing how the power supplying vehicle 120 heads toward the power receiving vehicle 110 and supplies power. In FIGS. 4 to 10, the block diagrams may be simplified to avoid complexity of the drawings.

[0069] 3 and 4, in order for the power receiving user to receive the services provided by the information processing system 1, the power receiving user installs a dedicated application on the first information terminal 10 and registers in advance with the server 30 via the dedicated application (S11). During the registration, the power receiving user inputs, into the first information terminal 10, vehicle information of the power receiving vehicle 110, registration information of the power receiving user, and payment information for the power receiving user to pay a usage fee for the service. As a result, the vehicle information of the power receiving vehicle 110, registration information of the power receiving user, and payment information for the power receiving user to pay a fee are stored in the first storage unit 14 of the first information terminal 10.

[0070] Furthermore, in order for the power supply user to receive the services provided by the information processing system 1, the power supply user installs a dedicated application on the second information terminal 20 and registers in advance with the server 30 via the dedicated application (S21). During the registration, the power supply user inputs, into the second information terminal 20, vehicle information of the power supply vehicle 120, registration information of the power supply user, and payment information for the power supply user to pay the usage fee for the service. As a result, the vehicle information of the power supply vehicle 120, registration information of the power supply user, and payment information for the power supply user to pay the fee are stored in the second storage unit 24 of the second information terminal 20.

[0071] 3 and 5, when the power receiving battery 114 of the power receiving user's power receiving vehicle 110 runs out of power, the power receiving user operates the first information terminal 10, which causes the first information terminal 10 to request rescue due to the power shortage from the server 30 (S12). At this time, when sending the rescue request to the server 30, the first information terminal 10 outputs information indicating the position of the first information terminal 10 detected by the first terminal position detection unit 12 (hereinafter referred to as position information) and electricity cost information indicating the electricity cost of the power receiving vehicle 110 to the server 30 via the first terminal communication unit 11 (S13). Furthermore, when the power receiving battery 114 of the power receiving vehicle 110 runs out of power, the power receiving vehicle 110 automatically outputs information indicating the position of the power receiving vehicle 110 detected by the first vehicle position detection unit 112 (hereinafter referred to as position information) to the server 30 via the first vehicle communication unit 111 (S14). In addition, the receiving vehicle 110 may output the location information of the first information terminal 10 and the location information of the receiving vehicle 110 to the server 30 via the first vehicle communication unit 111 at predetermined intervals, regardless of whether the receiving battery 114 has run out of power.

[0072] As a result, the wireless communication unit 31 of the server 30 acquires the location information of the first information terminal 10, the electricity cost information of the power receiving vehicle 110, and the location information of the power receiving vehicle 110.

[0073] Next, as shown in Figures 3 and 6, the distance calculation unit 32 acquires the map information stored in the third memory unit 35, and calculates the distance between the power receiving vehicle 110 and the EV charging facility E located in the vicinity of the power receiving vehicle 110 based on the location information of the power receiving vehicle 110 and the location information of the EV charging facility E included in the map information and located in the vicinity of the power receiving vehicle 110.

[0074] The required charge amount calculation unit 33 calculates the amount of power required when the power receiving vehicle 110 travels the distance calculated by the distance calculation unit 32, taking into account the electricity cost information of the power receiving vehicle 110 acquired by the wireless communication unit 31 (S31). At this time, the required charge amount calculation unit 33 may acquire information indicating the remaining capacity from the power receiving vehicle 110, and calculate the amount of power required for the vehicle to reach the EV charging facility E, taking into account the information indicating the remaining capacity of the power receiving vehicle 110.

[0075] When the required charge amount calculation unit 33 calculates the required amount of power, the list creation unit 34 of the server 30 searches for a power supply vehicle 120 that can supply the power receiving vehicle 110 with power equivalent to the required amount of power calculated by the required charge amount calculation unit 33. For example, the list creation unit 34 may search only for power supply vehicles 120 that are located within a predetermined distance from the power receiving vehicle 110 or power supply vehicles 120 that have a predetermined remaining capacity or more. In this case, the server 30 has previously acquired location information of the power receiving vehicle 110 and the power supply vehicle 120, and information indicating the total remaining capacity of the power supply vehicle 120.

[0076] Next, as shown in Figures 3 and 7, the list creation unit 34 starts a search to extract the power supplying vehicles 120 present around the power receiving vehicle 110, and outputs a rescue request to the second information terminal 20 owned by the power supplying user of the power supplying vehicle 120 via the wireless communication unit 31 (S32).

[0077] When the second information terminal 20 receives the rescue request from the server 30, the second display unit 23 of the second information terminal 20 displays the received rescue request. This allows the power supply user to recognize the rescue request from the power receiving user.

[0078] At this time, the second display unit 23 displays options for the power supply user to indicate whether or not to accept the rescue request. If the power supply user inputs into the input unit of the second information terminal 20 that the rescue request will not be accepted, the information processing system 1 ends the processing of FIG.

[0079] On the other hand, if the power supply user accepts the rescue request and makes an input indicating the intention to rescue into the input unit of the second information terminal 20 (S22), the second terminal communication unit 21 of the second information terminal 20 outputs the location information of the second information terminal 20 detected by the second terminal location detection unit 22 to the server 30 along with a notification of acceptance of the rescue request indicating the intention to rescue (S23).

[0080] Furthermore, when the power supply user inputs acceptance of the rescue request into the second information terminal 20, the power supply vehicle 120 from which the rescue request was made (hereinafter referred to as the rescue candidate vehicle) outputs information indicating the total remaining capacity, including information indicating the remaining capacity of the power supply battery 124 and information indicating the remaining capacity of the battery cells 131 of the external battery 130, to the server 30 (S23).

[0081] Specifically, when the power supply user inputs acceptance of the rescue request into the input unit of the second information terminal 20, the second information terminal 20 outputs a notification instruction to the rescue candidate vehicle and the external battery 130.

[0082] When the rescue candidate vehicle receives the notification instruction, the second vehicle position detection unit 122 outputs the detected position information of the rescue candidate vehicle to the server 30 via the second vehicle communication unit 121.

[0083] Furthermore, when the rescue candidate vehicle receives the notification instruction, second battery remaining capacity calculation unit 125 of the rescue candidate vehicle calculates information indicating the remaining capacity of power supply battery 124. Second battery remaining capacity calculation unit 125 automatically outputs the calculated information indicating the remaining capacity of power supply battery 124 to server 30 via second vehicle communication unit 121.

[0084] Furthermore, when the external battery 130 receives the notification instruction, the external battery remaining capacity calculation unit 132 of the external battery 130 calculates information indicating the remaining capacity of the battery cell 131. The external battery remaining capacity calculation unit 132 automatically outputs the calculated information indicating the remaining capacity of the external battery 130 to the server 30 via the second vehicle communication unit 121. Note that the external battery remaining capacity calculation unit 132 may output the information indicating the remaining capacity of the external battery 130 to the server 30 via the second vehicle communication unit 121 of the rescue candidate vehicle, or, if the external battery 130 is equipped with a wireless communication device, may output the information indicating the remaining capacity of the external battery 130 to the server 30 via the wireless communication device.

[0085] In the above description, the rescue candidate vehicles and the external battery 130 receive a notification instruction, and thereby output information indicating the remaining capacity of the rescue candidate vehicles and the external battery 130 to the server 30, but this is not limited to this. For example, when the power supply user inputs acceptance of the rescue request into the input unit of the second information terminal 20, the second information terminal 20 may display an input screen on the second display unit 23 for inputting the remaining capacity of the power supply battery 124 and the remaining capacity of the external battery 130. When the power supply user inputs the remaining capacity of the power supply battery 124 and the remaining capacity of the external battery 130 into the input unit of the input screen, the second information terminal 20 may output information indicating the remaining capacity of the rescue candidate vehicles and the external battery 130 to the server 30.

[0086] The wireless communication unit 31 of the server 30 acquires from the second information terminal 20 an acceptance response to the rescue request, the location information of the second information terminal 20, and from the rescue candidate vehicles, the location information of the rescue candidate vehicles, information indicating the remaining capacity of the power supply battery 124, and information indicating the remaining capacity of the external battery 130. Then, the list creation unit 34 ends the search.

[0087] 3 and 8, the server 30 acquires an acceptance response to the rescue request from the second information terminal 20, and the distance calculation unit 32 calculates the distance from the power receiving vehicle 110 to the rescue candidate vehicle. The processing unit 37 of the server 30 calculates the travel time based on the calculated distance and the amount to be paid to the rescue candidate vehicle. The processing unit 37 outputs the calculated travel time and amount to the second information terminal 20 or the rescue candidate vehicle via the wireless communication unit 31 (S33).

[0088] The second information terminal 20 may display the acquired travel time and amount on the second display unit 23. Furthermore, the rescue candidate vehicle may display the acquired travel time and amount on a display device mounted thereon. This allows the power supply user to recognize the travel time required to reach the power receiving vehicle 110 and the amount to be paid.

[0089] Next, a rescue request is made to the rescue candidate vehicles, the power supply user who made the rescue request expresses an intention to rescue, and the second information terminal 20 outputs a notification of acceptance of the rescue request to the server 30. The list creation unit 34 of the server 30 then includes the rescue candidate vehicles that expressed an intention to rescue in the rescue list and creates a rescue list that is a result of searching for rescue candidate vehicles. At this time, the list creation unit 34 creates a rescue list that includes rescue candidate vehicles that can supply power to the power receiving vehicle 110 based on information indicating the total remaining capacity of the power supply vehicle 120, location information of the rescue candidate vehicles, and the amount of power required by the power receiving vehicle 110.

[0090] Furthermore, the list creation unit 34 may create a rescue list that is the result of searching for rescue candidate vehicles, by including only rescue candidate vehicles that are within a predetermined distance based on the distance from the power receiving vehicle 110 to the rescue candidate vehicles. In other words, the list creation unit 34 may create a rescue list that is filtered to exclude power supply vehicles 120 that are far away from the power receiving vehicle 110.

[0091] Furthermore, the list creation unit 34 may create a rescue list that is a result of searching for rescue candidate vehicles, by including only rescue candidate vehicles with a predetermined remaining capacity or more in the rescue list based on the total remaining capacity of the rescue candidate vehicles calculated by the second battery remaining capacity calculation unit 125 and the external battery remaining capacity calculation unit 132. In other words, the list creation unit 34 may create a rescue list that is filtered to exclude power supply vehicles 120 with low remaining capacity.

[0092] The list creation unit 34 outputs the created rescue list to the first information terminal 10 via the wireless communication unit 31 (S34). In the rescue list, one or more rescue candidate vehicles are listed so that the time required for the rescue candidate vehicle to arrive at the power receiving vehicle 110 corresponds to the fee paid by the power receiving user for the rescue candidate vehicle.

[0093] Next, the first information terminal 10 acquires the rescue list from the server 30 and displays the rescue list on the first display unit 13. The power receiving user selects one rescue candidate vehicle from one or more rescue candidate vehicles while viewing the rescue list displayed on the first display unit 13. That is, the power receiving user inputs the selected rescue candidate vehicle into the input unit of the first information terminal 10.

[0094] 3 and 9, the input unit outputs information indicating the power supply user that identifies the rescue candidate vehicle selected and input by the power receiving user to the server 30 via the first terminal communication unit 11 (S15). The information indicating the power supply user includes the vehicle ID of the power supply vehicle 120, etc. (S16). The wireless communication unit 31 of the server 30 outputs a match establishment notification to one rescue candidate vehicle selected from one or more rescue candidate vehicles included in the rescue list, that is, the rescue candidate vehicle indicated by the vehicle ID acquired from the first information terminal 10. The match establishment notification includes details indicating the establishment of the match, the position of the power receiving vehicle 110, the driving route to the power receiving vehicle 110, etc. (S35).

[0095] As a result, the rescue candidate vehicle that has received the notification of successful matching from the server 30 is matched with the power receiving vehicle 110. The matched rescue candidate vehicle moves toward the power receiving vehicle 110 as the power supply vehicle 120, as shown in Fig. 3 and Fig. 10 , and after arriving, can supply power to the power receiver 113 of the power receiving vehicle 110 from the power supply device 123 of the power supply vehicle 120 and the power supply device 133 of the external battery 130.

[0096] <Action and effect> Next, the effects of the information processing system 1, the information processing method, and the program according to the present embodiment will be described.

[0097] As described above, the information processing system 1 of technique 1 according to this embodiment includes a distance calculation unit 32 that calculates the distance between the vehicle (power receiving vehicle 110) and the external power supply device (EV charging facility E) based on the position of the vehicle (power receiving vehicle 110) that is traveling while receiving power and the position of the external power supply device (EV charging facility E) that is present in the vicinity of the vehicle (power receiving vehicle 110), a required charge amount calculation unit 33 that calculates the amount of power required when the vehicle (power receiving vehicle 110) travels the distance calculated by the distance calculation unit 32, and an output unit that searches for a power supplying mobile object (power supplying vehicle 120) that can supply power equivalent to the amount of power required calculated by the required charge amount calculation unit 33 to the vehicle (power receiving vehicle 110), and outputs the search results.

[0098] According to this, even if the power receiving vehicle 110 runs out of power, the power receiving vehicle 110 can receive the necessary amount of power from the power supply vehicle 120. Therefore, the power receiving vehicle 110 can move to the EV charging facility E.

[0099] Therefore, even if the battery of the power receiving vehicle 110 runs out of power, the power receiving vehicle 110 can travel to the nearby EV charging facility E by receiving power from the power supply vehicle 120.

[0100] In addition, in the information processing system 1 of Technology 2 according to this embodiment, the output unit is a list creation unit 34 that creates a rescue list as a result of searching for a power supply mobile body (power supply vehicle 120) and outputs the created rescue list.

[0101] This allows a list (rescue list) of one or more power supply vehicles 120 that can supply power to the power receiving vehicle 110 to be generated, allowing the power receiving user to select a desired power supply vehicle 120 from the rescue list.

[0102] In the information processing system 1 of technique 3 according to the present embodiment, the power supplying mobile body (power supplying vehicle 120) has a battery (power supplying battery 124, battery cell 131), a remaining capacity calculation unit (second battery remaining capacity calculation unit 125, external battery remaining capacity calculation unit 132) that calculates the remaining capacity of the battery (power supplying battery 124, battery cell 131), and power supply devices 123 and 133 that supply power from the battery (power supplying battery 124, battery cell 131) to a vehicle (power receiving vehicle 110), and the information processing system The system 1 includes an acquisition unit (wireless communication unit 31) that acquires information indicating the remaining capacity and information (location information) indicating the location of the power supply mobile body (power supply vehicle 120) from the power supply mobile body (power supply vehicle 120), and the list creation unit 34 creates a rescue list including power supply mobile bodies (power supply vehicles 120) that can supply power to the vehicle (power receiving vehicle 110) based on the information indicating the remaining capacity and the information indicating the location of the power supply mobile body (power supply vehicle 120) acquired by the acquisition unit (wireless communication unit 31) and the required amount of power, and outputs the created rescue list.

[0103] This allows a rescue list to be created that includes power supply vehicles (power supply vehicles 120) that can supply power to the power receiving vehicle 110, so that the power receiving user can select a power supply vehicle 120 that is nearby, for example.

[0104] Furthermore, in the information processing system 1 of Technology 4 relating to this embodiment, the rescue list includes the time required for the power supplying mobile body (power supplying vehicle 120) to arrive at the vehicle (power receiving vehicle 110) and the fee to be paid to the power supplying mobile body (power supplying vehicle 120).

[0105] This allows the power receiving user to, for example, select a power supply vehicle 120 that requires a short travel time even if the fee is high, or select a power supply vehicle 120 that requires a long travel time even if the fee is low. Therefore, the power receiving vehicle 110 can select the desired power supply vehicle 120 by checking the travel time and the fee.

[0106] Furthermore, in the information processing system 1 of technique 5 relating to this embodiment, when a rescue request is made to a power supplying mobile body (power supplying vehicle 120) to supply power to a vehicle (power receiving vehicle 110), and the power supplying mobile body (power supplying vehicle 120) to which the rescue request was made expresses its intention to rescue, the list creation unit 34 includes the power supplying mobile body (power supplying vehicle 120) that expressed its intention to rescue in the rescue list.

[0107] According to this, since the power supply vehicles 120 that are willing to rescue are included in the rescue list, the power receiving user can have more options for selecting the power supply vehicle 120.

[0108] In addition, the information processing system 1 of technique 6 relating to this embodiment includes a processing unit 37 that calculates a travel time based on the distance from the vehicle (power receiving vehicle 110) to the power supplying mobile body (power supplying vehicle 120) for which a rescue request has been made, and an amount to be paid to the power supplying mobile body (power supplying vehicle 120) for which a rescue request has been made, and outputs the calculated travel time and amount to the power supplying mobile body (power supplying vehicle 120) for which a rescue request has been made.

[0109] This allows the power supply user to check the travel time and cost in advance, which allows the power supply user to determine whether or not to accept rescue from the power receiving vehicle 110 that has requested rescue.

[0110] In addition, the information processing system 1 of technology 7 relating to this embodiment is provided with a communication unit that outputs a matching establishment notification to one power supply vehicle (power supply vehicle 120) selected from one or more power supply vehicles (power supply vehicles 120) included in the rescue list.

[0111] This allows the power supply user to know that matching has been established, and so starts moving toward the power receiving vehicle 110. This allows the power supply vehicle 120 to arrive at the power receiving vehicle 110 as quickly as possible.

[0112] Furthermore, in the information processing system 1 of technique 8 relating to this embodiment, the distance calculation unit 32 calculates the distance from the vehicle to the power supplying mobile body (power supplying vehicle 120), and the list creation unit 34 creates a rescue list including only power supplying mobile bodies (power supplying vehicles 120) that are located within a predetermined distance based on the distance from the vehicle to the power supplying mobile body (power supplying vehicle 120), and outputs the created rescue list.

[0113] This allows a rescue list to be created that lists power supply vehicles 120 that are located near the power receiving vehicle 110, so that the power receiving user can select one power supply vehicle 120 from one or more power supply vehicles 120 that are located nearby. This allows the power supply vehicle 120 to arrive at the power receiving vehicle 110 quickly.

[0114] Furthermore, in the information processing system 1 of technique 9 relating to this embodiment, the list creation unit 34 creates a rescue list including only power supply vehicles (power supply vehicles 120) with a predetermined remaining capacity or more based on the remaining capacity of the battery (power supply battery 124) mounted on the power supply vehicle (power supply vehicle 120) calculated by the remaining capacity calculation unit, and outputs the created rescue list.

[0115] This allows a rescue list of power supply vehicles 120 with large remaining capacities to be created, allowing the power receiving user to select one power supply vehicle 120 from one or more power supply vehicles 120 with large remaining capacities. This prevents the power supply vehicle 120 from running out of power due to the remaining capacities of the power supply battery 124 and the battery cells 131 of the power supply vehicle 120 becoming low.

[0116] Furthermore, the information processing method of technique 10 according to this embodiment includes the steps of: a distance calculation unit 32 calculating the distance between the vehicle and the external power supply device based on the position of the vehicle that is running while receiving power and the positions of the external power supply devices present around the vehicle; a required charge amount calculation unit 33 calculating the amount of power required when the vehicle runs the distance calculated by the distance calculation unit 32; searching for a power supplying mobile object (power supplying vehicle 120) that can supply power to the vehicle equivalent to the amount of power required calculated by the required charge amount calculation unit 33; and an output unit outputting the search result.

[0117] In this case, the same effects as those described above are also achieved.

[0118] Furthermore, the program of Technique 11 according to the present embodiment is a program configured to cause a computer to execute the information processing method.

[0119] In this case, the same effects as those described above are also achieved.
