[Technical Field]

[0001] The present disclosure relates to a server, a management method, a system, and a display device. [Background technology]

[0002] International Publication No. 2013-137071 (Patent Document 1) discloses a system in which an electric vehicle is charged based on a reservation for use of a charger. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2013-137071 Summary of the Invention [Problem to be solved by the invention]

[0004] In some cases, users of electric vehicles want to make effective use of the time while their electric vehicles are being charged. In this case, it is conceivable to inspect and maintain the electric vehicle while it is being charged. Therefore, it is desirable to be able to appropriately inspect and maintain the electric vehicle while it is being charged (and discharged).

[0005] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide a server, a management method, a system, and a display device that enable appropriate inspection and maintenance of an electric vehicle while the electric vehicle is being charged and discharged. [Means for solving the problem]

[0006] A server according to a first aspect of the present disclosure is a server that manages inspection and maintenance of an electric vehicle, and includes a control unit that extracts at least one item from multiple inspection and maintenance items that can be performed during a reserved period based on the length of a reservation period during which power control including at least one of charging and discharging the battery of the electric vehicle is reserved by a user of the electric vehicle, and a communication unit that transmits information about the at least one item to at least one of the electric vehicle and the user's first information device.

[0007] As described above, the server according to the first aspect of the present disclosure transmits information about at least one item that can be performed during the reservation period to the at least one device. This allows the user to select an item that can be performed during the reservation period. As a result, inspection and maintenance of the electric vehicle can be performed appropriately during power control of the electric vehicle.

[0008] In the server according to the first aspect, the control unit preferably extracts the at least one item that can be completed within the reservation period. With this configuration, the user can select an inspection and maintenance item that can be completed within the reservation period.

[0009] In the server according to the first aspect, the control unit preferably extracts the at least one item based on the length of time required for each of the plurality of items and the schedule of the technician who will perform the inspection and maintenance. With this configuration, it is possible to prevent the user from being notified of an inspection and maintenance item that is difficult for the technician to handle.

[0010] In the server according to the first aspect, preferably, the at least one device includes a display unit. The control unit controls the transmission of signals to the at least one device via a communication unit, causing the display unit to display the at least one extracted item and the items not extracted from the plurality of items in different modes. With this configuration, the user can obtain information on the extracted items as well as information on the items not extracted.

[0011] In the server according to the first aspect, the control unit preferably extracts an item that is recommended to be performed from the at least one item based on information related to a travel schedule of the electric vehicle, and controls the control unit to transmit information related to which of the at least one item is the recommended item to the at least one device via the communication unit. With this configuration, the user can obtain information on the item that is recommended based on the travel schedule of the electric vehicle from among the items that can be performed within the reservation period.

[0012] In the server according to the first aspect, the control unit preferably extracts an item that is recommended to be performed from the at least one item based on historical information about inspection and maintenance of the electric vehicle, and controls the control unit to transmit information about the at least one item, which is the recommended item, to the at least one device via the communication unit. With this configuration, the user can obtain information about the item that is recommended based on the historical information about inspection and maintenance, from among the items that can be performed within the reservation period.

[0013] In the server that extracts at least one item that can be completed within the reservation period, preferably, the at least one device includes a display unit. The control unit predicts an estimated completion time for power control, and, if the at least one item includes multiple items and the estimated completion time is earlier than the end time of the reservation time, controls the at least one device to transmit, via the communication unit, a signal that causes the display unit to display, in different ways, items among the multiple items that will be completed by the estimated completion time and items among the multiple items that will be completed after the estimated completion time. With this configuration, if the estimated completion time of power control is earlier than the end time of the reservation period, it is possible to select items that can be completed by the estimated completion time. As a result, the user can depart the electric vehicle earlier.

[0014] In the server according to the first aspect, the control unit preferably controls the transmission of information on an item selected by the user from the at least one item to a second information device of a worker at a shop where the inspection and maintenance is to be performed, via the communication unit. With this configuration, the worker at the shop can smoothly start performing the inspection and maintenance item selected by the user.

[0015] A management method according to a second aspect of the present disclosure is a management method for managing inspection and maintenance of an electric vehicle, and includes the steps of: extracting at least one item from a plurality of inspection and maintenance items that can be performed during a reserved period based on the length of a reserved period during which at least one of charging and discharging of the battery of the electric vehicle is reserved by the user of the electric vehicle; and transmitting information on the at least one item to at least one of the electric vehicle and the user's information device.

[0016] In the management method according to the second aspect of the present disclosure, as described above, information on at least one item that can be performed during the reservation period is transmitted to the at least one device. This allows the user to select the item that can be performed during the reservation period. As a result, it is possible to provide a management method that allows appropriate inspection and maintenance of an electric vehicle during power control of the electric vehicle.

[0017] A system according to a third aspect of the present disclosure includes an electric vehicle and a server that manages inspection and maintenance of the electric vehicle. The server extracts at least one inspection and maintenance item that can be performed during a reservation period based on the length of a reservation period during which at least one of charging and discharging of the battery of the electric vehicle is reserved by a user of the electric vehicle, and transmits information on the at least one item to at least one of the electric vehicle and the user's information device.

[0018] In the system according to the third aspect of the present disclosure, as described above, information on at least one item that can be performed during the reservation period is transmitted to the at least one device. This allows the user to select an item that can be performed during the reservation period. As a result, it is possible to provide a system that can appropriately perform inspection and maintenance of an electric vehicle during power control of the electric vehicle.

[0019] In the system according to the third aspect, the server preferably receives information on an item selected by a user from the at least one item, and controls the electric vehicle based on the item selected by the user. With this configuration, the state of the electric vehicle is controlled based on the item selected by the user, making it easier to implement the item.

[0020] A display device according to a fourth aspect of the present disclosure is a display device provided in at least one of an electric vehicle and an information device of a user of the electric vehicle. The at least one device communicates with a server that extracts at least one item that can be performed during a reservation period from among multiple inspection and maintenance items of the electric vehicle, based on the length of a reservation period during which the user has reserved power control including at least one of charging and discharging of the electric vehicle's battery. The server transmits information on the at least one item to the at least one device. The display device includes a signal acquisition unit that acquires a signal based on information received by the at least one device, and a display unit that displays the at least one item based on the signal acquired by the signal acquisition unit.

[0021] In the display device according to the fourth aspect of the present disclosure, as described above, at least one item that can be carried out during the reservation period is displayed on the display unit, thereby providing a display device that allows appropriate inspection and maintenance of an electric vehicle during power control of the electric vehicle.

[0022] In the display device according to the fourth aspect, the display unit preferably displays the at least one item extracted by the server and the items not extracted by the server among the plurality of items in different modes. With this configuration, it is possible to provide a display device that is capable of acquiring information on the extracted items and information on the items not extracted.

[0023] In the display device according to the fourth aspect, the server preferably extracts an item that is recommended to be performed from the at least one item based on information related to a travel schedule of the electric vehicle. The display unit indicates which of the at least one item is a recommended item. With this configuration, it is possible to provide a display device that can acquire information on an item that is recommended based on a travel schedule of the electric vehicle from among items that can be performed within a reservation period.

[0024] In the display device according to the fourth aspect, the server preferably extracts a recommended item from the at least one item based on historical information about inspection and maintenance of the electric vehicle. The display unit indicates which of the at least one item is the recommended item. With this configuration, it is possible to provide a display device that can acquire information about recommended items based on historical information about inspection and maintenance, among items that can be performed within a reservation period.

[0025] In the display device according to the fourth aspect, preferably, the server predicts an estimated completion time for completing the power control. When at least one item includes multiple items and the estimated completion time is earlier than the end time of the reservation period, the display unit displays, in different ways, items among the multiple items that will be completed by the estimated completion time and items among the multiple items that will be completed after the estimated completion time. This configuration makes it possible to provide a display device that allows a user to select items that can be completed by the estimated completion time when the estimated completion time of the power control is earlier than the end time of the reservation period.

[0028] 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 numerals, and description thereof will not be repeated.

[0029] 1 is a diagram showing the configuration of a system 1 according to this embodiment. The system 1 includes a server 100, a terminal 200, an electric vehicle 10, and an EVSE (Electric Vehicle Supply Equipment) 20. The electric vehicle 10 is an example of "at least one of the devices" in the present disclosure.

[0030] The server 100, the terminal 200, and the EVSE 20 are provided at a dealer 900. The terminal 200 is a terminal used by a worker 210 at the dealer 900. Note that the dealer 900 may have multiple workers 210 available to perform inspection and maintenance, which will be described later. Note that the dealer 900 is an example of a "store" in the present disclosure.

[0031] The electric vehicle 10 includes, for example, a plug-in hybrid electric vehicle (PHEV), a battery electric vehicle (BEV), and a fuel cell electric vehicle (FCEV).

[0032] The electric vehicle 10 includes a navigation system 11 and a communication device 12. The electric vehicle 10 also includes a battery 13 that supplies power to electrical devices such as the navigation system 11 and the communication device 12. The communication device 12 may include a DCM (Data Communication Module) or a communication I / F compatible with 5G (fifth generation mobile communication system). The navigation system 11 is an example of a "display device" in the present disclosure.

[0033] The electric vehicle 10 is configured to be electrically connectable to the EVSE 20. A charging cable 21 connected to the EVSE 20 is connected to an inlet of the electric vehicle 10, thereby charging the battery 13 of the electric vehicle 10. Charging the battery 13 using the EVSE 20 is an example of "power control" in the present disclosure.

[0034] The server 100 is a server that manages inspection and maintenance of the electric vehicle 10. The server 100 also manages charging reservations for the electric vehicle 10 (and other electric vehicles) in the EVSE 20. Note that a server that manages inspection and maintenance of the electric vehicle 10 and a server that manages charging reservations for the electric vehicle 10 may be provided separately.

[0035] Server 100 is also configured to manage information on a plurality of registered electric vehicles 10 (hereinafter also referred to as "vehicle information"), information on each registered user (hereinafter also referred to as "user information"), and information on registered EVSEs 20 (hereinafter also referred to as "EVSE information"). The user information, vehicle information, and EVSE information are distinguished by identification information (ID) and stored in memory 102, which will be described later.

[0036] The user ID is identification information for identifying a user, and also functions as information (terminal ID) for identifying the mobile terminal 14 carried by the user. The server 100 is configured to store information received from the mobile terminal 14 separately for each user ID. The user information includes the communication address of the mobile terminal 14 carried by the user and the vehicle ID of the electric vehicle 10 belonging to the user. The mobile terminal 14 is an example of a "first information device" and an "information device."

[0037] The vehicle ID is identification information for identifying the electric vehicle 10. The vehicle ID may be a license plate or a VIN (Vehicle Identification Number). The vehicle information includes the travel schedule of each electric vehicle 10.

[0038] The EVSE-ID is identification information for identifying the EVSE 20. The EVSE information includes the communication address of each EVSE 20 and the status of the electric vehicle 10 connected to each EVSE 20. The EVSE information also includes information indicating the combination of the electric vehicle 10 and the EVSE 20 that are connected to each other (for example, a combination of the EVSE-ID and the vehicle ID).

[0039] The server 100 includes a processor 101, a memory 102, and a communication unit 103. The processor 101 is an example of a "control unit" in the present disclosure.

[0040] The memory 102 stores the programs executed by the processor 101 as well as information used in the programs (for example, maps, formulas, and various parameters). The memory 102 also stores schedule information for the worker 210. The schedule information is updated when the schedule of the worker 210 is changed.

[0041] The memory 102 also stores information about each of a plurality of inspection and maintenance items for the electric vehicle 10. Specifically, the memory 102 stores information about the time required for each of the plurality of items. For example, the memory 102 stores information that checking tire pressure and replacing air conditioner filters take 30 minutes and 60 minutes, respectively. The memory 102 also stores information about the costs required for each of the plurality of items.

[0042] The communication unit 103 includes various communication I / Fs. The processor 101 controls the communication unit 103. Specifically, the processor 101 communicates with the communication device 12 (or the mobile terminal 14) of the electric vehicle 10, the EVSE 20, and the terminal 200 via the communication unit 103.

[0043] As shown in FIG. 2, the navigation system 11 includes a display screen 11a and a signal receiving unit 11b. The display screen 11a displays an image based on a signal received by the signal receiving unit 11b. The signal receiving unit 11b receives (acquires) a signal based on a signal received by the electric vehicle 10 (communication device 12) from the server 100. The signal based on the signal received from the server 100 may be the signal itself received by the communication device 12 from the server 100, or may be a signal received by the communication device 12 from the server 100 that has been converted by a predetermined processing unit. The display screen 11a and the signal receiving unit 11b are examples of a "display unit" and a "signal acquiring unit," respectively, in the present disclosure.

[0044] 3, the mobile terminal 14 includes a display device 140 having a display screen 141 and a signal receiving unit 142. The mobile terminal 14 also includes a communication unit 143. The display screen 141 displays an image based on a signal received by the signal receiving unit 142. The signal receiving unit 142 receives (acquires) a signal based on a signal received by the communication unit 143 from the server 100. The signal based on the signal received from the server 100 may be the signal itself received by the communication unit 143 from the server 100, or may be a signal received by the communication unit 143 from the server 100 and converted by a predetermined processing unit.

[0045] Here, a user of the electric vehicle 10 may wish to make effective use of the time while the electric vehicle 10 is being charged. In this case, it may be considered to inspect and maintain the electric vehicle 10 while the electric vehicle 10 is being charged. Therefore, it is desirable to appropriately inspect and maintain the electric vehicle 10 while the electric vehicle 10 is being charged.

[0046] Therefore, in this embodiment, the processor 101 extracts items that can be carried out (completed) during the reservation period from among a plurality of inspection and maintenance items, based on the length of a reservation period for which charging of the battery 13 of the electric vehicle 10 is reserved by the user, and transmits information on the extracted items to the electric vehicle 10 (communication device 12) via the communication unit 103. In other words, the processor 101 transmits a signal to the electric vehicle 10 via the communication unit 103 to notify the electric vehicle 10 of the extracted items. That is, the processor 101 transmits a signal to the electric vehicle 10 (communication device 12) via the communication unit 103 to control the electric vehicle 10 (navigation system 11) so as to notify the user of the extracted items. This will be described in detail with reference to the sequence diagram of FIG. 4.

[0047] (Management method) A method for managing inspection and maintenance of the electric vehicle 10 by the system 1 will be described with reference to the sequence diagram of FIG.

[0048] In step S1, the user of the electric vehicle 10 accesses a reservation site for reserving the use of the EVSE 20 through the navigation system 11. As a result, a reservation screen 30 for the EVSE 20 (see FIG. 5) is displayed on the navigation system 11. Note that access to the reservation site and display of the reservation screen 30 may be performed by the mobile terminal 14. Note that, as shown in FIG. 5, free items and paid items are displayed separately on the reservation screen 30. Furthermore, the configuration of the reservation screen 30 is not limited to the example shown in FIG. 5 and FIG. 6 described below.

[0049] The reservation screen 30 displays a plurality of inspection and maintenance items that can be handled by the dealer 900. Note that, at the stage of step S1, selection operations for the plurality of items displayed on the reservation screen 30 are not accepted. For example, at step S1, the selection buttons 34 corresponding to the respective items are displayed in gray (shown by dashed lines in FIG. 5).

[0050] Free services include "air pressure inspection," "brake oil inspection," "washer fluid refill," "coating condition inspection," "window cleaning," and "trade-in price assessment." Paid services include "interior cleaning" and "water repellent."

[0051] In step S2, the user of electric vehicle 10 inputs a reservation period for which charging of battery 13 is scheduled to be reserved in input field 31 of reservation screen 30. Input field 31 includes field 31a for inputting the start time of the reservation period and field 31b for inputting the end time of the reservation period.

[0052] In step S3, processor 101 extracts, from among the multiple inspection and maintenance items, items that can be performed during the reservation period set by the user in step S2, based on the length of the reservation period. For example, if the user sets the reservation period from 2:00 PM to 2:30 PM in step S2, from among the multiple items, items that can be completed within 30 minutes are extracted.

[0053] The processor 101 extracts items that can be completed within the reservation period and that the worker 210 can handle during the reservation period. Therefore, items that no worker 210 can handle during the reservation period (because the worker 210 is engaged in other work) are not extracted.

[0054] In step S4, the user of the electric vehicle 10 inputs a target value of the SOC of the battery 13 to be increased by charging in the input field 32 of the reservation screen 30. Note that if no value is input in the input field 32, the target value may be automatically set to 100%.

[0055] In step S5, the user of the electric vehicle 10 inputs the current SOC of the battery 13 in the input field 33 of the reservation screen 30. If no value is input in the input field 33, the current SOC may be automatically set to a predetermined value (for example, 30%). Information about the current SOC may also be acquired by the server 100 (communication unit 103). The processor 101 may also estimate the current SOC based on the driving history of the electric vehicle 10, etc.

[0056] In step S6, the processor 101 estimates (calculates) the time when the SOC of the electric vehicle 10 will reach the target SOC value set in step S4. Specifically, the processor 101 estimates the time based on the difference between the target value and the current SOC input (acquired) in step S5. For example, the processor 101 estimates the time by dividing the amount of power corresponding to the difference by the amount of charging power per unit time. In this way, the processor 101 predicts the charging completion time when charging of the electric vehicle 10 will be completed.

[0057] In step S7, processor 101 extracts, from among the multiple inspection and maintenance items, items that can be performed (completed) by the charging completion time predicted in step S6. For example, if the reservation period is from 2:00 PM to 2:30 PM and the time required to reach the target SOC estimated in step S6 is 20 minutes, items that can be performed (completed) by 2:20 PM are extracted. Note that if the time required to reach the target SOC estimated in step S6 is longer than the length of the reservation period set in step S2, the processing of step S7 is not executed. The predicted charging completion time is an example of the "estimated completion time" in the present disclosure.

[0058] The processor 101 extracts items that the worker 210 can handle between the charging start time and the charging completion time. Therefore, items for which no worker 210 is available (because the worker 210 is engaged in other work) between the charging start time and the charging completion time are not extracted. The processes of steps S4 to S7 may be performed before step S2.

[0059] In step S8, the server 100 (communication unit 103) acquires information about a travel schedule for the electric vehicle 10. The information about the travel schedule includes, for example, information about a travel route and a destination after charging of the electric vehicle 10 is completed. The information about the travel schedule may be transmitted to the server 100 from the electric vehicle 10 or a server (not shown) that manages information about the electric vehicle 10.

[0060] In step S9, based on the information acquired in step S8, the processor 101 extracts, from among the multiple inspection and maintenance items, items that are recommended for the electric vehicle 10. For example, if the electric vehicle 10 is scheduled to use an expressway after charging, an item that requires attention when traveling at high speeds (for example, checking tire air pressure) may be extracted.

[0061] In step S10, the server 100 (communication unit 103) acquires information on history information of inspections and maintenance that the electric vehicle 10 has undergone in the past. The history information includes information on the items of inspections and maintenance that the electric vehicle 10 has undergone in the past and the inspection dates corresponding to the items. The history information may be transmitted to the server 100 from the electric vehicle 10 or a server (not shown) that manages information about the electric vehicle 10.

[0062] In step S11, based on the information acquired in step S10, the processor 101 extracts, from among the plurality of inspection and maintenance items, items that are recommended for the electric vehicle 10. For example, items that have not been performed for a predetermined period of time (e.g., six months or more) may be extracted.

[0063] The processes of steps S8 to S11 may be performed at the stage of step S1, for example.

[0064] In step S12, the processor 101 transmits information on the extraction results obtained in each of steps S3, S7, S9, and S11 to the electric vehicle 10. Specifically, the processor 101 transmits a signal to the communication device 12 of the electric vehicle 10 to display a reservation screen 30 based on the extraction results.

[0065] The signal receiving unit 11b of the navigation system 11 receives a signal based on the signal received by the communication device 12. As a result, the reservation screen 30 updated based on the extraction result is displayed on the display screen 11a of the navigation system 11.

[0066] A signal for displaying the reservation screen 30 based on the extraction result may be transmitted to the communication unit 143 of the mobile terminal 14. In this case, the display screen 141 and the signal receiving unit 142 are examples of the "display unit" and the "signal acquisition unit" of the present disclosure, respectively. In the above case, the mobile terminal 14 is an example of the "at least one device" of the present disclosure. A signal for displaying the reservation screen 30 based on the extraction result may be transmitted to both the electric vehicle 10 (communication device 12) and the mobile terminal 14.

[0067] Specifically, processor 101 transmits, via communication unit 103 to electric-powered vehicle 10 (communication device 12), a signal that causes the items extracted in step S3 and the items not extracted in step S3 to be displayed in different modes. In particular, processor 101 changes the color of selection buttons 34 corresponding to the items extracted in step S3 from gray to green (represented by diagonal lines slanting downward to the right in FIG. 6). Note that the selection buttons 34 corresponding to the items extracted in step S3 are changed to a selectable state on the reservation screen 30. Processor 101 also maintains the color of selection buttons 34 corresponding to items not extracted in step S3 as gray. Note that the method of distinguishing between items extracted in step S3 and items not extracted in step S3 is not limited to the above example.

[0068] Furthermore, the processor 101 transmits to the electric vehicle 10 (communication device 12) via the communication unit 103 a signal for displaying the items extracted in the processing of step S7 and the items extracted by the processing of step S3 but not extracted in the processing of step S7 in different modes on the reservation screen 30. In other words, the processor 101 performs processing for displaying the items that can be performed (completed) by the predicted charging completion time and the items that can be performed (completed) after the charging completion time within the reservation period in different modes.

[0069] Specifically, processor 101 performs processing to display in green the selection buttons 34 corresponding to items that can be performed after the charging completion time within the reservation period. On the other hand, processor 101 performs processing to display in orange (represented by diagonal lines slanting upward to the right in FIG. 6) the selection buttons 34 corresponding to items that can be performed before the charging completion time within the reservation period. Note that the method of distinguishing between items that can be performed after the charging completion time within the reservation period and items that can be performed before the charging completion time is not limited to the above example.

[0070] Furthermore, processor 101 performs processing to attach, for example, a white star-shaped mark 35 (see FIG. 6 ) to selection buttons 34 corresponding to items extracted based on the information on the travel schedule of electric vehicle 10 (information in S8) from among the items extracted in the processing of step S3 or S7. This notifies the user which items have been extracted based on the information on the travel schedule of electric vehicle 10. Note that the color, shape, and position of mark 35 are not limited to the above example. Furthermore, the user may be notified of the items extracted based on the information on the travel schedule by a method other than attaching mark 35 (for example, a method of sending a notification message to the user).

[0071] Furthermore, processor 101 performs processing to attach, for example, a black star-shaped mark 36 (see FIG. 6 ) to selection button 34 corresponding to an item extracted based on the inspection and maintenance history information (information at S10) of electric vehicle 10, among the items extracted in the processing of step S3 or S7. This notifies the user of which item has been extracted based on the inspection and maintenance history information of electric vehicle 10. Note that the color, shape, and position of mark 36 are not limited to the above example. Furthermore, the user may be notified of the item extracted based on the inspection and maintenance history information by a method other than attaching mark 36 (for example, by sending a notification message to the user).

[0072] In step S13, the user selects the desired inspection and maintenance items on the reservation screen 30 updated by the processing of step S12. The user can select multiple items. If the multiple items selected by the user cannot be executed in parallel with each other and must be executed serially (see FIG. 7), processor 101 adjusts reservation screen 30 so that the total time required for the selected multiple items is equal to or less than the length of the reservation period.

[0073] For example, suppose the reservation period is 30 minutes, and the user initially selects an item with a required time of 10 minutes. In this case, processor 101 adjusts reservation screen 30 so that only items with a required time of 20 minutes or less (30 minutes - 10 minutes) can be selected. Specifically, processor 101 makes selection button 34 corresponding to an item with a required time longer than 20 minutes unselectable. Note that items that can be executed in parallel with the initially selected item with a required time of 10 minutes (see FIG. 7) can be selected as long as their required time is 30 minutes or less. Also, item selection may be performed after charging has started.

[0074] In step S14, the processor 101 transmits information about the item selected in step S13 to the terminal 200 of the worker 210. Specifically, the processor 101 transmits a signal notifying the terminal 200 of the item selected in step S13 via the communication unit 103. As a result, the item selected in step S13 is notified to the worker 210 by the terminal 200. The terminal 200 is an example of a "second information device" in the present disclosure.

[0075] In step S15, the processor 101 controls the electric vehicle 10 based on the item selected in step S13. For example, when an item that requires the worker 210 to enter the vehicle (for example, interior cleaning) is selected in step S13, the processor 101 unlocks the doors of the electric vehicle 10. In the above cases, the processor 101 may also perform control to disconnect communication between the electric vehicle 10 and the mobile terminal 14 or to lower the volume of the music player of the navigation system 11. In addition, the processor 101 may control the electronically controlled suspension when checking tire air pressure is selected by the user. The processing of step S15 may be performed simultaneously with step S14.

[0076] As described above, in this embodiment, the processor 101 extracts, from among multiple inspection and maintenance items, items that can be performed during the reservation period based on the length of the reservation period for which charging of the battery 13 of the electric vehicle 10 is reserved. Then, the communication unit 103 notifies the user of the extracted items. This makes it possible to prevent the user from selecting inspection and maintenance items that are difficult to complete within the reservation period.

[0077] In the above embodiment, an example in which charging of the electric vehicle 10 is reserved is shown, but the present disclosure is not limited to this. For example, discharging in response to a request from a VPP or energy management may be reserved. In this case, the discharging is an example of "power control" in the present disclosure. Furthermore, both charging and discharging may be performed.

[0078] In the above embodiment, an example is shown in which items that can be completed within the reservation period are extracted, but the present disclosure is not limited to this. For example, items whose completion time exceeds the end time of the reservation period may be extracted as long as at least a part of the work is performed within the reservation period.

[0079] In the above embodiment, an example has been shown in which items extracted by the processor 101 and items not extracted by the processor 101 are displayed in different modes, but the present disclosure is not limited to this. Items not extracted by the processor 101 may not be displayed.

[0080] In the above embodiment, an example has been described in which the items extracted by the server 100 are displayed on the navigation system 11, but the present disclosure is not limited to this. The items extracted by the server 100 may be notified to the user by voice.

[0081] In the above embodiment, an example has been described in which the EVSE 20 is provided in the dealer 900, but the present disclosure is not limited to this. The EVSE 20 may be provided in a parking lot or the like. In this case, a worker from the dealer 900 may be dispatched to the EVSE 20 to perform inspection and maintenance.

[0082] In the above embodiment, the inspection and maintenance items are described as items that are manually performed by the worker 210, but the present disclosure is not limited to this. For example, the inspection and maintenance items may include a process for updating a vehicle program via OTA (Over The Air).

[0083] In the above embodiment, in addition to extracting feasible items based on the length of the reservation period, extraction based on the target SOC (extraction of S7), extraction based on the driving schedule (extraction of S9), and extraction based on the inspection history (extraction of S11) are performed. However, the present disclosure is not limited to this. Extraction of step S7, extraction of step S9, and extraction of step S11 may not be performed. Alternatively, only one of extraction of step S7, extraction of step S9, and extraction of step S11 may be performed. Alternatively, only two of extraction of step S7, extraction of step S9, and extraction of step S11 may be performed.

[0084] In the above embodiment, an example has been shown in which items are extracted based on the length of time required for each of a plurality of inspection and maintenance items and the schedule of the worker 210, but the present disclosure is not limited to this. The extraction may be performed based on the length of time required for each of a plurality of items, regardless of the schedule of the worker 210.

[0085] In the above embodiment, an example is shown in which items that can be completed by the charging completion time when charging of the battery 13 is completed and items that can be completed after the charging completion time within the reservation period are displayed in different modes, but the present disclosure is not limited to this. For example, items that can be completed after the charging completion time may not be displayed, and items that can be completed by the charging completion time may be displayed.

[0086] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present disclosure is defined by the claims, not by the description of the above embodiments, and is intended to include all modifications within the meaning and scope of the claims.
