[0011] [Figure 1] 1 is a diagram illustrating an overall configuration of a power supply system according to an embodiment of the present invention. [Diagram 2] FIG. 4 is a sequence diagram illustrating an example of a power supply request process executed in the power supply system. [Diagram 3] FIG. 11 is a diagram illustrating an example of a power supply vehicle information list transmitted from a server. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0013] FIG. 1 is a diagram illustrating a schematic overall configuration of a power supply system 1 according to the present embodiment. The power supply system 1 includes a power supply vehicle group 100, a power receiving target group 200, and a server 300. The power supply vehicle group 100 is configured from a plurality of power supply vehicles 10. The power supply vehicle 10 may be any type of vehicle that can supply power to the outside of the vehicle. The power supply vehicle 10 may be an electric vehicle equipped with an externally chargeable power storage device. For example, the power supply vehicle 10 may be a BEV (Battery Electric Vehicle), a HEV (Hybrid Electric Vehicle), a FCEV (Fuel Cell Electric Vehicle), or a PHEV (Plug-in Hybrid Electric Vehicle).

[0014] The power receiving target group 200 is a vehicle, a house, a facility, etc. to which power is supplied (receives power) from the power supply vehicle 10, and may be, for example, an electric vehicle 20, a house 30, etc. The electric vehicle 20 may be a BEV that runs on power stored in a battery BT, or may be an HEV, a PHEV, or an FCEV. When the server 300 receives a power supply request from a user of the power receiving target group 200, it matches the power receiving target (electric vehicle 20, house 30) that has requested power supply with the power supply vehicle 10. The server 300 may be a computer including a processor 310, a RAM (Random Access Memory) 320, and a storage device 330.

[0015] Each power supply vehicle 10, or a mobile terminal 11 owned by a user who manages each power supply vehicle 10, is configured to be able to communicate with the server 300 through the network NW. The power supply vehicle 10 and the corresponding mobile terminal 11 can communicate with each other, for example, by short-range communication, and the mobile terminal 11 can acquire various information about the power supply vehicle 10.

[0016] An in-vehicle terminal of the electric vehicle 20 to be the power recipient, or a mobile terminal 21 of a user who owns the electric vehicle 20, is configured to be able to communicate with the server 300 via the network NW. A home 30 to be the power recipient (more specifically, a HEMS controller), or a mobile terminal 31 of a user who owns the home 30, is configured to be able to communicate with the server 300 via the network NW. These terminals operated by users of the power recipient group 200 correspond to an example of a "power receiving side terminal" in the present disclosure. Also, the server 300 corresponds to an example of a "management terminal" in the present disclosure.

[0017] In the power supply system 1, when the battery BT of the electric vehicle 20 runs out of power, when the power supply to the house 30 is stopped, when there is a power shortage in an off-grid area, etc., a user who is a target to receive power can make a power supply request (power reception request) to the power supply vehicle 10.

[0018] FIG. 2 is a sequence diagram showing an example of a power supply request process executed in the power supply system 1. For convenience, three power supply vehicles 10 (mobile terminals 11A, 11B, and 11C) are illustrated in FIG. 2. When a user of the power receiving target group 200 wants to receive power from the power supply vehicle 10 (when a user of the power receiving target group 200 wants to receive power), the user transmits a power supply request to the server 300 (step 10 (hereinafter, step is abbreviated as "S")). For example, when the electric vehicle 20 runs out of power, the user of the electric vehicle 20 operates the mobile terminal 21 (or the in-vehicle terminal of the electric vehicle 20) to transmit a power supply request to the server 300. The power supply request transmitted to the server 300 includes information such as a user ID (user identification number), the location (location information) of the electric vehicle 20, and the required amount of power supply (reception). The location of the electric vehicle 20 may be information acquired by a GPS (Global Positioning System) device mounted on the electric vehicle 20.

[0019] When the server 300 receives a power supply request from the mobile terminal 21, etc., it transmits the fact that there is a power supply request to the power supply vehicle group 100 (in this embodiment, the mobile terminal 11 corresponding to each power supply vehicle 10) (S50). The power supply request may include position information of the electric vehicle 20 and information on the required amount of power supply. When the power supply request is received, a user who manages each power supply vehicle 10 determines whether or not to accept the power supply request. A user who accepts the power supply request operates the mobile terminal 11 to transmit vehicle information of the power supply vehicle 10 (S20). The vehicle information includes a vehicle ID which is an identification number of the power supply vehicle 10, the current position of the power supply vehicle 10, the fee for power supply, etc. Details of the vehicle information will be described later.

[0020] The server 300 starts the matching process (S60) when receiving the vehicle information from the mobile terminal 11. In the matching process, the server 300 first transmits a power supply vehicle information list to the mobile terminal 21 (S60a).

[0021] 3 is a diagram showing an example of a power supply vehicle information list transmitted from the server 300. This power supply vehicle information corresponds to "power supply information" in the present disclosure. The power supply vehicle information list (hereinafter also simply referred to as "list") includes a "vehicle ID" which is an identification number of the power supply vehicle 10, a "current location" of the power supply vehicle 10, an "expected arrival time" to the location of the electric vehicle 20, a "power supplyable amount", a "maximum output", an "electricity charge" per unit of power, an "hourly charge", a "fee" per unit of time, a "CO2 emission amount" at the time of power supply, a "CO2 emission amount" at the time of dispatch (when moving to the location of the electric vehicle 20), and a past "evaluation".

[0022] The list is an aggregation of vehicle information received by the server 300 from the mobile terminal 11 (power supply vehicle 10). The "current location" includes the "distance" (preferably the route distance) between the power supply vehicle 10 and the electric vehicle 20. The "distance" and "estimated arrival time" are calculated by the server 300 based on the current location and the location information of the electric vehicle 20 received from the mobile terminal 11. The "available power supply amount," "maximum output," "electricity fee," "hourly fee," "fee," and "CO2 emission amount" during power supply are values ​​received from the mobile terminal 11.

[0023] The "hourly rate" may be a rate set by the user of the power supply vehicle 10 when supplying power for a long period of time with a small power supply. The "fee" may be a fee set arbitrarily by the user of the power supply vehicle 10 as an expense required for travel when dispatching the vehicle.

[0024] The amount of CO2 emissions per unit distance traveled is stored in association with the vehicle ID in the storage device 330 of the server 300. The "amount of CO2 emissions" at the time of vehicle dispatch is calculated by the server 300 based on the "distance" and the amount of CO2 emissions per unit distance traveled.

[0025] The "rating" is linked to the vehicle ID and stored in the storage device 330. The "rating" is evaluated by the user of the power receiving target group 200 every time power supply from the power supply vehicle 10 to the power receiving target group 200 is completed, and is updated as needed.

[0026] In S21, the mobile terminal 21 that has received the list displays the received list on the mobile terminal 21. Then, when the user of the mobile terminal 21 (electrically powered vehicle 20) refers to the list and selects a power supply vehicle 10 that satisfies the user's request, the selection result is transmitted to the server 300.

[0027] When the server 300 receives the selection result from the mobile terminal 21, it transmits a vehicle allocation request to the mobile terminal 11 corresponding to the selected power supply vehicle 10 (S60b). In the example of Fig. 3, the vehicle allocation request is transmitted to the mobile terminal 11C.

[0028] The mobile terminal 11C that has received the dispatch request displays a notification of the dispatch request (S22). When the user who manages the power supply vehicle 10 approves the dispatch and operates the mobile terminal 11C, an approval notification is transmitted from the mobile terminal 11C to the server 300 (S24). The user who transmitted the approval notification dispatches (moves) the power supply vehicle 10 to the location of the electric vehicle 20 as appropriate.

[0029] When the server 300 receives the approval notification, it transmits a result notification to the mobile terminal 21 (S60c). The result notification includes information that the selected (requested) power supply vehicle 10 will be dispatched. When the mobile terminal 21 receives the result notification, it displays that the selected power supply vehicle 10 will be dispatched (S14).

[0030] When the power supply to the electric vehicle 20 that is the power receiving target is completed, the mobile terminal 21 is operated to perform post-termination processing (S16). First, the mobile terminal 21 performs payment processing for the power supply fee (S16a). When the payment processing for the power supply fee is completed in the mobile terminal 21, the server 300 performs settlement processing and pays a reward to the manager of the power supply vehicle 10 (mobile terminal 11C) (S70). In addition, the mobile terminal 21 evaluates the current power supply (S16b). The evaluation may be, for example, an evaluation rank and an arbitrary comment. When the server 300 receives the evaluation, it updates the evaluation information stored in the storage device 330. The evaluation information is linked to the vehicle ID of the power supply vehicle 10 and stored in the storage device 330.

[0031] According to this embodiment, when a user of a power receiving target (for example, the electric vehicle 20, the house 30) makes a power supply request, a power receiving side terminal (mobile terminals 21, 31, etc.) managed by the user displays a list of power supply information including the distance between the power supply vehicle 10 and the power receiving target (for example, the electric vehicle 20, the house 30) and the amount of power that can be supplied by the power supply vehicle 10. The user can refer to the information displayed in the list, select a power supply vehicle 10 according to his / her needs, and receive power supply, thereby satisfying the user's request.

[0032] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present disclosure is defined by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
