[0040] [3. Hardware configuration] 3 and 4, the hardware configurations of the server device 1 and the user terminal 11 will be described. Components that are common to the server device 1 and the user terminal 11 will be given the same reference numerals, and detailed descriptions thereof will be omitted.

[0041] (Hardware configuration of server device 1) Next, the hardware configuration of the server device 1 will be described with reference to FIG. 3. As shown in FIG. 3, the server device 1 of this embodiment uses, for example, a computer. The server device 1 includes a CPU (or GPU) 30.

[0046] [4. Registration process to System 10] (Registration process) Next, the flow of the process of registering the user terminal 11, the electric vehicle 12, and the external power supply device 13 in the system 10 will be described. In this embodiment, when using the system 10, the user registers the user terminal 11, the electric vehicle 12, and the external power supply device 13. Note that the system 10 may be configured to be usable even if the user has not registered in advance. The following describes user registration of the user terminal 11. Registration of the electric vehicle 12 and the external power supply device 13 is almost the same as registration of the user terminal 11, so detailed description will be omitted.

[0047] (T1) An unregistered user who wishes to use the system 10 registers via the server device 1 or an external pre-registered login server device (hereinafter referred to as a server device, etc.). The user requests the server device, etc. to send a registration form via the user terminal 11 or another terminal (hereinafter referred to as a communication terminal, etc.) that the user owns.

[0054] (Installing an external power supply on an electric vehicle) If the position information 21c of the electric vehicle 12 and the position information 22c of the external power supply device 13 are the same or almost the same, the server device or the like determines that the external power supply device 13 is loaded on the electric vehicle 12. Then, the server device or the like registers the loading relationship in the other information 21e and 22d, respectively.

[0055] (Registration of usage information 6a) In this embodiment, the usage information 6a is registered as other information 21e and 22d in the electric vehicle information DB 21 and the power supply unit information DB 22.

[0056] [5. Program] (Flowchart showing the processing of the system 10) The processing flow of the system 10 will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an embodiment of the processing of the programs 36, 39, 39a, and 39b used in the server device 1, the user terminal 11, the electric vehicle 12, and the external power supply device 13.

[0057] (System 10 begins operation) When a condition 15 such as a disaster is satisfied, operation of the system 10 begins. In this embodiment, for example, when the server device 1 receives a special weather warning, the server device 1 sets a disaster area A. In this embodiment, the disaster area A is the same as the range of the warning issued by a government agency. When the user terminal 11 accesses the server device 1, it transmits location information 22c. When accessing the server device 1 by a user terminal 11 located within the disaster area A, the server device 1 permits access, but does not permit access by a user terminal 11 located outside the disaster area A.

[0058] (S1: Request for map information) In response to a user operation, the user terminal 11 requests map information from the server device 1. The map information displays the positions of the electric vehicle 12 and the external power supply device 13 on a map (see FIG. 7). The positions of the electric vehicle 12 and the external power supply device 13 are based on position information 21c, 22c (see FIG. 5).

[0059] (S2: Sending map information) The CPU 30 of the server device 1 receives a request for map information from the user terminal 11. The server device 1 transmits the map information to the user terminal 11.

[0060] FIG. 7 shows the display screen 19 of the display unit 11a of the user terminal 11. Map information is displayed on the display screen 19. Reference numeral 7 on the display screen 19 indicates an electric vehicle 12. The display element indicated by reference numeral 7 represents an electric vehicle 12 that can be immediately powered. On the other hand, the display element indicated by reference numeral 9 represents an electric vehicle 12 that requires an external power supply device 13. An exclamation mark indicates that power cannot be immediately supplied. The display element indicated by reference numeral 8 represents the external power supply device 13. The star display element indicated by reference numeral 23 represents the current location of the user terminal 11. Reference numeral 25 represents a landmark spot, such as a shrine, a shop, or a hotel.

[0061] (S3: Request for information on electric vehicle / external power supply) In this embodiment, when the user touches a portion of the display unit 11 corresponding to the table elements 7, 8, and 9, the user terminal 11 requests the server device 1 for detailed information on the display elements 7, 8, and 9 corresponding to the touched portion.

[0062] (S4: Transmitting information about electric vehicle / external power supply) The server device 1 acquires information including the requested electric vehicle power supply information 21b / external power supply compatibility information 22b based on the electric vehicle DB 21 / power supply device DB 22, and transmits the information to the user terminal 11. The power supply information 21b / external power supply compatibility information 22b of the touched display element is displayed on the display screen 19 of the user terminal 11. Note that the information described in the other information 21e, 22d, including the remaining battery charge, may also be transmitted.

[0063] Furthermore, in this embodiment, when the user touches a portion of the display unit 11 of the display element 9 marked with an exclamation mark, the display elements 8 of the external power supply device 13 that are compatible with the touched electric vehicle 12 are highlighted. Examples of highlighting include, but are not limited to, brightening the corresponding display element 8, enlarging it, or surrounding it with a frame. Note that incompatible display elements 9 may also be made invisible.

[0064] For example, according to the display screen 19, even if the user reaches the electric vehicle (reference number 9) closest to the current location 23, power cannot be supplied immediately because an external power supply reference number 8 is required. Therefore, the user can make an action plan from the beginning to move toward the electric vehicle reference number 7. The user, who is a disaster victim, can gather information and act efficiently.

[0065] (S5: Request for key information) Next, the user requests the key information 21d of the electric vehicle 12 that the user wishes to unlock from the server device 1. In this embodiment, by touching again the portion of the display unit 11 that corresponds to the display element 7 of the electric vehicle that the user wishes to unlock, the request for the key information 21d is sent to the server device 1 together with the user's ID 20a.

[0066] (S6: User information confirmation and recording) Upon receiving the request for the key information 21d, the server device 1 records information including at least the user ID 20a and the ID 21a of the selected electric vehicle in the storage unit 31. By keeping a usage record, the server device 1 encourages the user to use the service responsibly. The date and time when the request was received may also be stored.
