[1. Overview of the battery sharing system]
FIG. 1 is a diagram illustrating an example of the configuration of a battery sharing system 1 according to this embodiment. The battery sharing system 1 is a system that lends batteries to users on the premise that the batteries will be shared by multiple users. Hereinafter, this battery lending service will be referred to as a "battery sharing service." FIG. 1 illustrates a configuration in which the battery sharing system 1 provides a battery sharing service to a user U. The battery sharing system 1 includes, for example, a battery exchange station 300, a management device 400, and a terminal device 500 of the user U (hereinafter referred to as a "user terminal device"). The battery exchange station 300, the management device 400, and the user terminal device 500 can communicate with each other via a communication network NW. For simplicity, one battery exchange station 300 is illustrated here; however, the battery sharing system 1 may include multiple battery exchange stations 300.

[2. Overview of each part of the battery sharing system]
The communication network NW may be a wired communication transmission path, a wireless communication transmission path, or a combination of a wireless communication transmission path and a wired communication transmission path. The communication network NW may include a wireless packet communication network, the Internet, a P2P network, a dedicated line, a VPN (Virtual Private Network), a power line communication line, a vehicle-to-vehicle communication line, a road-to-vehicle communication line, etc. The communication network NW may include (i) a mobile communication network such as a mobile phone network, or (ii) a wireless communication network such as a wireless MAN (Metropolitan Area Network) (e.g., WiMAX (registered trademark)), a wireless LAN (e.g., Wi-Fi (registered trademark)), Bluetooth (registered trademark), Zigbee (registered trademark), or NFC (Near Field Communication).

The battery 100 is a battery device that is detachably mounted on the electric motorcycle 200. The battery 100 supplies power to the mounted electric motorcycle 200. The battery 100 is charged by the battery exchange station 300. For example, when the remaining capacity of the battery 100 mounted on the electric motorcycle 200 becomes low, the user U requests the management device 400 to lend out the battery 100 stored in a specific battery exchange station 300. When the user U arrives at the battery exchange station 300, the user U removes the battery 100 from the electric motorcycle 200 and returns it to a return space provided at the battery exchange station 300. The battery exchange station 300 charges the returned battery 100 at an appropriate time, preparing it for its next use.

The electric motorcycle 200 consumes power supplied by the battery 100. More specifically, the electric motorcycle 200 moves using the power supplied by the battery 100. If the battery 100 has a memory device, the electric motorcycle 200 may store at least one of the riding history and operation history of the electric motorcycle 200 in the memory device.

1, electric motorcycle 200 is shown as an example of a use of battery 100 by user U, and the use of battery 100 is not limited to electric motorcycle 200. Battery 100 may be used as a power source for any electrical device. For example, battery 100 may be used as a power source for a mobile object that obtains propulsion power from a motor, or as a power source for a stationary power supply device. Examples of mobile objects include automobiles, motorcycles, stand-up vehicles with power units, ships, and aircraft. Examples of automobiles include gasoline-powered vehicles, diesel-powered vehicles, electric vehicles, fuel cell vehicles, hybrid vehicles, small commuter vehicles, and electric carts. Examples of motorcycles include motorcycles, tricycles, and electric bicycles. Examples of ships include ships, hovercrafts, jet skis, submarines, submersibles, and underwater scooters. Examples of aircraft include airplanes, airships, balloons, helicopters, and drones.

The battery exchange station 300 holds one or more batteries 100. The battery exchange station 300 charges each of the one or more batteries 100. The battery exchange station 300 executes a battery 100 lending process in response to a request from a user U. For example, the battery 100 lending process includes user authentication for the user U and a battery 100 disbursement process.

For example, user authentication is achieved through cooperative processing between the battery exchange station 300 and the management device 400. More specifically, the battery exchange station 300 requests the management device 400 to authenticate a user U who is about to begin using the station, and can determine whether the authentication was successful based on the authentication result returned from the management device 400. That is, in this embodiment, the management device 400 has a user authentication function, and the battery exchange station 300 allows a user who has successfully passed user authentication to use the station.

The management device 400 performs various management operations related to the battery sharing system 1. For example, the management device 400 monitors the status and manages the operation of the battery exchange station 300. Furthermore, for example, the management device 400 manages the usage of each of the one or more batteries 100. For example, the battery sharing system 1 manages the lending status (e.g., available for lending, unavailable for lending, being lent, etc.), operating status (e.g., charging, discharging, standby, etc.), charging status (e.g., current SOC), storage status (e.g., temperature, humidity, etc.), and degradation status of each of the one or more batteries 100.

The management device 400 also has the function of providing user U with information regarding the availability of the battery sharing service (hereinafter referred to as "availability information") by operating in cooperation with the user terminal device 500. For example, the management device 400 accepts various requests from user U via the user terminal device 500, executes processing related to the accepted requests, and returns the processing results to the user terminal device 500. Examples of such requests include a search request to search for battery exchange stations 300 that meet specific conditions, or a reservation request to reserve any or a specific battery 100 stored in a specific battery exchange station 300. The user terminal device 500 also outputs information received from the management device 400. The information output may be in the form of image output, audio output, output (recording) to a storage medium, output (transmission) to another communication device, or other forms.

The user terminal device 500 may be any information processing terminal capable of communicating with the battery exchange station 300 and the management device 400 via the communication network NW, and its details are not particularly limited. The user terminal device 500 may be a personal computer, or a portable terminal such as a mobile phone, smartphone, PDA, tablet, notebook computer or laptop computer, or wearable computer.

[3. Battery Rental]
The battery exchange station 300 determines which batteries 100 to lend to the user U from among the batteries 100 housed therein, based on the state of the batteries 100 housed therein and various attribute information (hereinafter referred to as "user information") managed for the user U. The user information may include any information managed for each user regarding the battery sharing service. For example, the user information of the user U may include information such as the content of the service contract concluded between the user U and the service provider when using the battery sharing service, the user U's battery 100 usage history, reservations for use of the battery exchange station 300, and reservations for lending the battery 100. For example, if the user U has a service contract for the use of two batteries 100, the battery exchange station 300 selects two batteries 100 to lend from among the batteries 100 housed therein whose charging rates exceed the lending threshold.

The priority determination unit 354 determines the priority of each of the multiple batteries 100 held by the battery exchange station 300, in terms of the battery to be loaned or charged. The priority of a battery 100 to be loaned may be whether the battery 100 can be loaned or may be the priority level for loaning the battery 100. The priority of a battery 100 to be charged may be whether the battery 100 can be charged or may be the priority level for charging the battery 100. The above priority levels may be indicated by continuous numerical values or by graded divisions. The priority of a battery 100 to be loaned may be the same as the priority of a battery 100 to be charged.

The lending target determination unit 358 determines a battery 100 to be provided to a specific user in response to a request from the user from among one or more batteries 100 stored in the battery storage chamber 322 of one or more charging units 320. The lending target determination unit 358 may determine a battery 100 to be lent from among the multiple batteries 100 held in the battery exchange station 300.

For example, the lending target determination unit 358 accesses the user management information 416 described below to obtain information indicating the user's user attributes (user information). Based on the user's user attributes, the lending target determination unit 358 extracts a battery 100 to be provided to the user from among the multiple batteries 100 held by the battery exchange station 300. This allows the lending target determination unit 358 to determine a battery 100 to be provided to the user from among the multiple batteries 100 in response to a request from the user.

As described above, the user attributes include user U's contract information regarding the battery sharing service and user U's usage history of the battery 100. In addition to these, the user attributes may also include the usage trends of the battery 100 analyzed for each user. The usage trends of the battery 100 here refer to the tendency of how the user uses the battery 100, and can be analyzed by the margin estimation unit 460, rental price determination unit 470, station information transmission unit 480, etc., which will be described later.

The station information acquisition unit 420 acquires necessary information from the battery exchange station 300 and the user terminal device 500 as appropriate, and generates or updates the above-mentioned battery management information 412, station management information 414, and user management information 416.

The status monitoring unit 430 monitors each battery exchange station 300 that is the subject of management based on the station management information 414. The station management information 414 is updated by the station information acquisition unit 420 as appropriate according to the monitoring cycle of the status monitoring unit 430.

The battery management unit 440 manages one or more batteries 100 housed in each battery exchange station 300 based on the battery management information 412. The battery management unit 440 manages, for example, at least one of the operating status, charging status, storage status, and deterioration status of the battery 100 to be managed.

The user authentication unit 450 performs user authentication for users of the battery sharing service. User authentication may be based on a combination of a user ID and password, or on biometric information such as fingerprints, voiceprints, or iris information. The user authentication unit 450 may also perform user authentication for users of the battery exchange station 300 upon request from the battery exchange station 300.

The margin estimation unit 460 estimates the margin of a battery exchange station 300 designated as the estimation target (hereinafter referred to as the "target station") at a specified specific timing (hereinafter referred to as the "designated timing"). The margin is the degree of likelihood that the target station will be able to lend out a battery 100 at the specified timing. The margin estimation unit 460 estimates the margin of the target station based on station information acquired from the target station. As described above, the station information includes one or both of the battery 100 exchange history at the battery exchange station 300 and the charging completion time for each battery 100 housed in the battery exchange station 300. The charging completion time is the time required to complete charging of the battery 100. Here, charging completion means that the battery 100 has been charged to a level at which it can be lent out, and does not necessarily mean that it is fully charged. The level at which the battery 100 can be lent out may be set appropriately depending on the intended use of the battery 100, the degree of deterioration of the battery 100, etc. Here, the full charge time is updated as needed as the charging progresses, representing the time from the current time until the charging is completed. For example, if the charging rate of a certain battery 100 at time T1 is 50% and the time until the charging is completed is one hour, the charging completion time of the battery 100 at time T1 is one hour. If the charging rate is then 60% at time T2 and the time until the charging is completed is 50 minutes, the charging completion time of the battery 100 at time T2 is updated to 50 minutes. The update interval may be set appropriately depending on the allowable error in estimating the margin of error.

The rental price determination unit 470 determines the rental price of the battery 100 at the target station and the specified timing based on the margin estimation result by the margin estimation unit 460. For example, the rental price determination unit 470 may determine a higher rental price the higher the margin of the target station at the specified timing, and a lower rental price the lower the margin. The rental price determination unit 470 may be configured to update the rental price when the margin is estimated, or may be configured to determine the rental price when the management device 400 accepts a rental reservation for the battery 100 from the user terminal device 500. The rental price determination unit 470 may determine the rental price based on the most recently estimated margin, or may instruct the margin estimation unit 460 to estimate the margin when determining the rental price.

The station information transmission unit 480 generates station information including information about batteries 100 available for loan from the battery exchange station 300 and transmits it to the user terminal device 500. More specifically, the station information is used when the user terminal device 500 displays availability information about the battery exchange station 300, and includes the above-mentioned margin. In addition, the station information transmission unit 480 may include some or all of the battery management information 412 and station management information 414 stored in the memory unit 410, as well as various information obtained based on this management information, in the station information. The station information transmission unit 480 may also generate station information by inquiring of the necessary information from the battery exchange station 300 at the appropriate time.

8. Configuration of User Terminal Device
FIG. 7 is a diagram showing an example of the configuration of a user terminal device 500. The user terminal device 500 includes, for example, a storage unit 510, an input unit 520, a display unit 530, and a control unit 540. These components are implemented by, for example, a hardware processor such as a CPU executing a program (software). Some or all of these components may be implemented by hardware (including circuitry) such as an LSI, ASIC, FPGA, or GPU, or may be implemented by a combination of software and hardware. The program may be stored in advance in a storage device (a storage device with a non-transitory storage medium) such as an HDD, SSD, or flash memory, or may be stored in a removable storage medium (a non-transitory storage medium) such as a DVD or CD-ROM, and installed by inserting the storage medium into a drive device.

The memory unit 510 includes a non-volatile storage device such as an HDD, SSD, or flash memory. The memory unit 510 is used as a storage area for various information related to the operation of the user terminal device 500. For example, the memory unit 510 stores a user application program (hereinafter referred to as the "terminal app") 511 that displays availability information of battery exchange stations 300 in the form of a map. More specifically, the terminal app 511 displays the locations of the battery exchange stations 300 on a map, and displays information indicating the remaining capacity of the batteries 100 available for rental at each battery exchange station 300 (hereinafter referred to as "remaining capacity information") on the map in correspondence with each station. For example, the remaining capacity information may be displayed near the corresponding battery exchange station 300, or may be displayed anywhere on the map along with a display indicating the corresponding battery exchange station 300.

Figure 8 shows an example of the display of remaining capacity information by the terminal app 511. For example, the first display example G11 in Figure 8 displays the number of batteries 100 currently available for rental (rentable number) for a specific battery exchange station 300 (hereinafter referred to as "my station") registered in advance by the user, along with the location of my station on a map, as remaining capacity information. Furthermore, the second display example G12 displays the time required until the number of available batteries becomes zero, along with the location of my station on a map, as remaining capacity information. While Figure 8 shows an example of displaying current remaining capacity information for a battery exchange station 300, the terminal app 511 can display remaining capacity information for any future time in addition to displaying current remaining capacity information. The terminal app 511 displays such remaining capacity information based on station information received from the management device 400. The remaining capacity information may be included in the station information in advance, or may be generated by the terminal app 511 based on the station information.

Returning to Figure 7, the input unit 520 includes input devices such as a mouse, keyboard, and touch panel. The input unit 520 accepts various operations input by the user and converts the input operations into electrical signals, which are output to the control unit 540. The input unit 520 may also be equipped with an audio input device such as a microphone, and configured to accept operation input via audio input. Furthermore, if the input unit 520 is equipped with a touch panel, the input unit 520 may be configured integrally with the display unit 530. Furthermore, the input unit 520 is not limited to being an input device configured as part of the user terminal device 500. For example, the input unit 520 may be configured as an input interface that inputs electrical signals indicating operations on the user terminal device 500 from an external device configured separately from the user terminal device 500.

The display unit 530 is configured using a display device such as a CRT (Cathode Ray Tube) display, a liquid crystal display, or an organic EL display. Alternatively, the display unit 530 may be configured as an interface that connects these display devices to the device itself. For example, the screen of the terminal app 511 is displayed on the display unit 530.

The control unit 540 controls the operation of each unit of the user terminal device 500. The control unit 540 includes, for example, an authentication request unit 541, a display control unit 543, and a condition specification unit 545. For example, the authentication request unit 541, the display control unit 543, and the condition specification unit 545 are generated by the control unit 540 executing the terminal app 511.

The authentication request unit 541 requests the management device 400 to perform user authentication for the user. At this time, the authentication request unit 541 transmits the user's authentication information required for user authentication to the management device 400.

The display control unit 543 executes a display control process to control the screen display of the terminal app 511 based on the station information acquired from the management device 400. For example, the station information includes information such as the identification information, location information, battery information, and margin of the battery exchange station 300 to be displayed (hereinafter referred to as the "target station"). The display control unit 543 recognizes the location of the target station based on the various information included in the station information, acquires the margin of power information of the target station, and displays the acquired margin of power information on a map in association with the location of the target station (see, for example, Figure 7).

In addition to display control based on such station information, the display control unit 543 may also perform display control based on the user attributes of the user that can be recognized based on the results of user authentication. As described above, the user attributes of the users are managed by the user management information 416 in the management device 400. In this case, the user authentication unit 450 acquires the user attributes from the user management information 416 for a user who has successfully been authenticated and transmits them to the user terminal device 500. This allows the display control unit 543 to recognize the user attributes of the user of the device itself (the user terminal device 500) based on the results of the user authentication. For example, the display control unit 543 can recognize the electrical equipment for which the user intends to use the battery 100 (hereinafter referred to as "application equipment"), the user's usage history of the battery 100, and the like, based on the user authentication results. Furthermore, the display control unit 543 can analyze the user's usage trends of the battery 100 by analyzing the usage history of the battery 100 and battery information corresponding to the usage history. For example, the display control unit 543 can estimate the degree of deterioration of the battery 100 caused by use by the user and analyze the deterioration pattern. For example, the degree of deterioration of the battery 100 can be recognized from changes in the SOC, changes in the full charge capacity, changes in the time required for charging, etc. The display control unit 543 may be configured to determine the battery exchange stations 300 to be displayed and the batteries 100 to be available for rental based on various user attributes recognized in accordance with the results of user authentication in this way, and to display availability information within that range.

The condition specification unit 545 specifies the margin estimation conditions to be notified as part of the station information when the user terminal device 500 requests the management device 400 to provide station information. As described above, the margin estimation conditions include the target station, which is the battery exchange station 300 to be estimated, and the specified timing, which is the timing at which the estimation is to be performed. The condition specification unit 545 accepts input of the estimation conditions by the user, for example, via the input unit 520. The input estimation conditions are transmitted to the management device 400 together with the request to provide station information.

In this embodiment, the user terminal device 500 can display the margin of the specified battery exchange station 300 (target station) at the specified timing (specified timing) as availability information for the target station.

[9. Availability Information Providing Process]
9 is a sequence chart showing an example of a process flow in which user terminal device 500 cooperates with management device 400 to display the margin at a specified timing (designated timing) as availability information for battery exchange station 300 designated as a target station. First, an operation to start terminal application 511 is input in user terminal device 500 (step S101). In response to this start-up operation, control unit 540 starts terminal application 511, thereby generating authentication request unit 541 and display control unit 543 in user terminal device 500.

When the terminal app 511 is launched on the user terminal device 500, the authentication request unit 541 first requests user authentication of the user from the management device 400 (step S102). At this time, the authentication request unit 541 transmits the user's authentication information (e.g., user ID and password) to the management device 400.

Next, in the management device 400, the user authentication unit 450 receives a request from the user terminal device 500 and performs user authentication for the requesting user (step S103). The user authentication unit 450 notifies the user terminal device 500 of the result of the user authentication (step S104). The following describes the case where user authentication of the user is successful in step S103. However, if user authentication fails in step S103, the user authentication unit 450 notifies the requesting user terminal device 500 that user authentication has failed in step S104, and the series of processes ends.

Next, in the user terminal device 500, in response to successful user authentication of the user, the display control unit 543 requests the management device 400 to provide station information (step S105). At this time, the display control unit 543 presents the estimation conditions related to the estimation of the margin of safety to the management device 400. For example, the display control unit 543 may present to the management device 400 the estimation conditions that the user has registered in advance in the user terminal device 500, or may be configured to accept input of estimation conditions from the user when requesting the provision of station information.

Next, in the management device 400, the margin estimation unit 460 recognizes the target station and the specified timing based on the estimation conditions notified by the user terminal device 500, and estimates the margin of the target station at the specified timing based on various management information (battery management information 412, station management information 414, user management information 416, etc.) stored in the memory unit 410 (step S106). Next, the rental price determination unit 470 determines the rental price of the battery 100 at the specified timing of the target station based on the margin estimated by the margin estimation unit 460 in step S106 (step S107). Next, the station information transmission unit 480 generates station information necessary for display control of the terminal app 511 in the user terminal device 500 and transmits it to the user terminal device 500 (step S108). At this time, the station information transmission unit 480 transmits the margin estimated in step S106 and the rental price determined in step S107 to the user terminal device 500, including the station information.

Depending on the timing of receiving the request for station information, it is possible that the management device 400 has not acquired sufficient management information. If such a possibility is anticipated, the station information acquisition unit 420 may be configured to request update information from the battery exchange station 300 (step S201) and acquire the update information from the battery exchange station 300 (step S202) in response to successful user authentication. In this case, the station information acquisition unit 420 may perform an information update process for various management information in the memory unit 410 based on the update information acquired from the battery exchange station 300 (step S203), and then proceed to step S106. This information update process allows the management device 400 to provide more appropriate station information to the user terminal device 500.

Next, in the user terminal device 500, the display control unit 543 executes a display control process to display availability information of the battery exchange station 300 on the display unit 530 based on the station information provided by the management device 400 (step S108). For example, the display control unit 543 recognizes the target station and the specified timing based on the station information, and displays the margin of the target station at the specified timing. Note that there may be one target station or multiple target stations. Similarly, there may be one specified timing or multiple specified timings. Furthermore, the margin of margin may be displayed on a map in association with the position of the target station displayed on the map by the terminal app 511.

In addition, in the example of Figure 9, a case was described in which the margin of the battery exchange station 300 is displayed in response to the startup of the terminal app 511, but the timing at which the margin of the battery exchange station 300 is displayed may be any timing. For example, the terminal app 511 may display the margin of the battery as illustrated in Figure 8 upon startup, and then execute processing to display the margin of the battery in response to a user operation instructing the display of the margin of the battery. For example, in the example of Figure 9, the user terminal device 500 may execute processing from step S102 onwards in response to an operation being input to display the margin of the battery. In this case, if user authentication has already been successful, the processing related to user authentication (steps S102 to S104) may be omitted.

Figure 10 is a diagram showing an example of a method in which the margin estimation unit 460 in the management device 400 estimates the margin at a specified timing for a battery exchange station 300 designated as a target station. For example, as shown in the matrix in Figure 9, the margin estimation unit 460 can determine the margin based on a combination of the predicted number of batteries 100 that have completed charging at the target station at the specified timing (hereinafter referred to as the "number of completed charges") and a predicted value of the degree of congestion in the use of batteries 100 at the target station at the specified timing (hereinafter referred to as the "usage congestion degree").

The degree of usage congestion is represented, for example, by the number of battery 100 replacements predicted to occur at the specified timing. For example, the margin estimation unit 460 can classify the number of battery 100 replacements that occurred at the specified timing among the battery 100 replacement histories included in the station information for the same day of the week and the same time period as the specified timing, thereby classifying the number of replacements into several groups of representative numbers (which may be a range of numbers), and predict the occurrence frequency of each group as the degree of usage congestion.

Here, the number of completed charges represents the available lending capacity of the battery 100, while the usage congestion level is a factor that reduces the available lending capacity. Therefore, the actual available lending capacity of the battery 100 at the specified timing of the target station is expressed as an index value obtained by subtracting the usage congestion level from the number of completed charges. For example, the example matrix in Figure 10 shows an example of determining the available lending capacity when the number of completed charges is assumed to be "0 to 1," "2 to 5," or "6 or more," and the usage congestion level is assumed to be "0 times," "1 to 2 times," or "3 or more."

In the example of Figure 10, for example, if the number of completed charges is "2 to 5" and the usage congestion level is "0 times," the actual remaining lending capacity of battery 100 is "2 to 5," so the margin is determined to be "high (sunny mark)." Also, for example, if the number of completed charges is "2 to 5" and the usage congestion level is "1 to 2 times," the actual remaining lending capacity of battery 100 is "1 to 3," so the margin is determined to be "medium (cloudy mark)." Also, for example, if the number of completed charges is "2 to 5" and the usage congestion level is "3 or more times," the actual remaining lending capacity of battery 100 is "0 to 2," so the margin is determined to be "low (rainy mark)."

The margin estimation unit 460 may perform this margin determination in response to receiving a request for station information from the user terminal device 500, or may create a matrix like the example in Figure 10 as a lookup table for combinations of the number of completed charges and the usage congestion level that can be predicted. In this case, the margin estimation unit 460 may determine the margin by referencing the lookup table using the predicted results of the number of completed charges and the usage congestion level obtained in response to the request for station information. While the margin is expressed as a graded level of strength (e.g., high margin, medium margin, low margin, etc.) here, the margin may also be expressed numerically. For example, the margin estimation unit 460 may use the maximum imaginable margin as a reference value and calculate the margin as a ratio or percentage of the reference value.

Figure 11 is a diagram showing an example of a display when the terminal app 511 on the user terminal device 500 displays the remaining capacity information of a target station. For example, the display example in Figure 11 shows that when two battery exchange stations 300 (my stations) whose installation locations are represented by icons C1 and C2 on the map are specified as the target stations and the time period from 4:00 PM to 6:00 PM is specified as the specified timing, the remaining capacity information including the respective margins is displayed on the map in correspondence with each installation location.

11, the first display example G21 notifies the user that the battery exchange station 300 associated with icon C1 has a high margin of availability at the specified time and has a surplus of rentable batteries 100 in stock. Also, in FIG. 11, the second display example G22 notifies the user that the battery exchange station 300 associated with icon C2 has a low margin of availability at the specified time and has no rentable batteries 100 in stock, and suggests that the user search for alternative battery exchange stations 300 in the vicinity of the target station. In this way, by displaying the marginal capacity information for the specified battery exchange station 300 at the specified time, the user can recognize the appropriate timing for using the battery exchange station 300 in advance and select a more appropriate battery exchange station 300 to use.

For example, in the example of FIG. 11, if a user is at point P1 shown on the map, the user recognizes that My Station A, associated with icon C1, offers a higher margin of safety between 4:00 PM and 6:00 PM than My Station B, associated with icon C2, and can plan to use My Station A between 4:00 PM and 6:00 PM. Furthermore, in this case, if the user recognizes that My Station A offers a higher margin of safety between 4:00 PM and 6:00 PM but considers it to be far from the user's current location, the user can search for available battery exchange stations 300 near My Station B, which is closer to the user's current location. In this case, the display control unit 543 of the terminal app 511, in response to an operation instructing a search for battery exchange stations 300, identifies battery exchange stations 300 near My Station B, sets them as target stations, and transmits a request for station information for the same specified time period (4:00 PM to 6:00 PM in this example) to the management device 400. The user terminal device 500 may pre-store location information for battery exchange stations 300 other than My Station, or may inquire about this information from the management device 400.

The second display example G22 is an example of a mode in which, for a target station whose margin is below a predetermined value, battery exchange stations 300 other than the target station are displayed as replacement candidates. While FIG. 11 illustrates a case in which the predetermined value is set to zero, this predetermined value is not limited to zero and may be set arbitrarily. Also, while FIG. 11 illustrates a case in which a search for battery exchange stations 300 that are replacement candidates for the target station is performed in response to user operation, such a search for replacement candidates may be performed as appropriate in response to the estimated margin for the target station, without relying on user operation. In this case, the margin estimation unit 460 of the management device 400 may search for replacement battery exchange stations 300 in the vicinity of the target station and transmit the search results to the user terminal device 500 in station information. In this case, the margin for the replacement candidates may be estimated and the estimated margin may be transmitted to the user terminal device 500 in station information.

According to the battery sharing system 1 of this embodiment configured as above, more appropriate information can be provided to users regarding the availability of battery exchange stations 300 in the battery sharing service.
