The display unit 235 displays various information when the user uses the battery exchange station 200, and receives input of predetermined information (for example, authentication information) from the user.

The reading unit 240 reads authentication information and other information from a user card, which is an example of a medium held by a user. The authentication information includes, for example, a user ID and password. The user card is, for example, a contactless IC card. Alternatively, the user card may be a contact type IC card. Further, the user card may be issued for each electric vehicle 10 used by the user, for example. In this case, the authentication information includes a card ID and a vehicle ID as identification information for identifying the user card. Further, the medium held by the user may be an electronic device such as a smartphone or a tablet terminal. Further, the manner in which the reading unit 240 acquires the authentication information is not limited to the manner in which it is acquired through communication, but may be in a manner in which the information is optically read from a code image such as a QR code (registered trademark). The reading unit 240 outputs the read authentication information to the control unit 260. The reading unit 240 is an example of a device attached to the battery exchange device station 200 (battery exchange device).

The authentication unit 245 determines whether or not to permit the user to use the battery exchange station 200 based on the authentication information received from the display unit 235 or the authentication information read by the reading unit 240. Note that the authentication information may be obtained from, for example, voice from the user collected by a microphone (not shown) of the battery exchange station 200. For example, the authentication unit 245 uses the authentication information to check the authentication list 282 stored in the storage unit 280, and when the authentication list 282 includes information that matches the authentication information, Determine that the authentication was successful. The authentication list 282 is authentication information for verification distributed by the management server 300 at a predetermined timing or cycle. The authentication information for verification includes authentication information of one or more users. The authentication information for verification includes, for example, information such as a user ID that permits use of the battery exchange station 200, a card ID, a password, an expiration date, the number of removable batteries 100 that can be lent, and status. The expiration date is, for example, the last day of the period in which the battery exchange station 200 can be used. The number of removable batteries 100 that can be rented is, for example, the number of removable batteries 100 that can be mounted on the electric vehicle 10 associated with the card ID. The status is information indicating the usage status of the battery exchange system 1 in the electric vehicle 10 associated with the card ID. The usage status includes, for example, the removable battery 100 being lent, being authenticated for battery replacement, or being temporarily or permanently suspended due to unauthorized use by the user. is included.

If it is determined that the user has been successfully authenticated, the authentication unit 245 determines whether the user satisfies predetermined usage conditions. The predetermined usage condition is, for example, that the current date (usage date) has not passed the expiration date included in the authentication list 282. Further, the predetermined usage conditions may include that the user has not engaged in any unauthorized use or the like and is unable to use the service (use is suspended). For example, the authentication unit 245 allows the user to use (return and lend) the battery exchange station 200 if the current date has not passed the expiration date included in the authentication list 282.

Furthermore, when the authentication list 282 does not include information that matches the authentication information, the authentication unit 245 may send the authentication information from the communication unit 250 to the management server 300 to inquire about authentication. That is, the authentication unit 245 may be provided on the management server 300 side. In this case, the authentication unit 245 acquires the authentication result and verification authentication information from the management server 300 as an inquiry result, and if the user authentication is successful, uses the verification authentication information to perform the predetermined usage. Determine whether the condition is met. Furthermore, if predetermined usage conditions are met, the user is permitted to use the battery exchange station 200.

Further, if the user's authentication is not successful or if the predetermined usage conditions are not met, the authentication unit 245 displays information indicating that the service is unavailable on the display unit 235 and notifies the user. Note that the above-mentioned authentication using the user ID etc. does not necessarily need to be performed every time there is an exchange. Furthermore, instead of (or in addition to) the above-described authentication, the authentication unit 245 may perform biometric authentication using biometric information such as the user's fingerprint information, voiceprint information, and iris information. In this case, biometric information for verification is stored in the authentication list 282, and the authentication unit 245 performs authentication by comparing the biometric information and the biometric information for verification.

The communication unit 250 includes wired communication devices such as terminal adapters and Ethernet (registered trademark) communication devices, and wireless communication devices such as Wi-Fi adapters, 3G/LTE, 4G, and Bluetooth, and communicates with the management server 300 via the network NW. , communicate with terminal devices, etc.

The exchange control unit 262, charging control unit 264, battery information upload unit 268, and usage information upload unit 270 are configured by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Realized. In addition, some or all of the functions may be realized by hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or GPU (Graphics Processing Unit). Alternatively, it may be realized by cooperation of software and hardware. The above-mentioned program may be stored in advance in a storage device such as an HDD or a flash memory (a storage device equipped with a non-transitory storage medium) of the battery exchange station 200, or may be stored in a storage device such as a DVD, CD-ROM, memory card, etc. It may be installed in the storage device of the battery exchange station 200 by attaching the storage medium (non-transitory storage medium) to a drive device, card slot, or the like.

The storage unit 280 may be realized by the various storage devices described above, EEPROM (Electrically Erasable Programmable Read Only Memory), ROM (Read Only Memory), RAM (Random Access Memory), or the like. The storage unit 280 stores, for example, an authentication list 282, battery information 284, programs, and other various information. Authentication list 282 is distributed by management server 300. The battery information 284 stores battery IDs assigned to one or more removable batteries 100 managed within the battery exchange station 200 and SOC information (an example of battery status) for each removable battery 100.

The exchange control unit 262 controls the return of the used removable battery 100 mounted on the electric vehicle 10 and the lending of the charged removable battery 100 based on the authentication result by the authentication unit 245. For example, the exchange control unit 262 opens the slot 210 for storing the used removable battery 100 when returning the battery, or opens the slot 210 in which the charged removable battery 100 is stored when lending the battery. Furthermore, the exchange control unit 262 may determine whether the stored used removable battery 100 is a genuine (genuine product) removable battery. In this case, the exchange control unit 262 acquires the battery ID of the stored removable battery 100 and makes an inquiry to the management server 300 based on the acquired battery ID and user information (user ID, card ID). The management server 300 compares the battery ID and user information obtained from the battery exchange station 200 with the user management table 352, etc., and determines that the battery is a regular removable battery if matching information exists. , if matching information does not exist, it is determined that the battery is not a genuine removable battery. The case where the battery is not a genuine removable battery includes, for example, the case where the battery is not a genuine product or the case where the removable battery is returned by a user who is not the user who lent the battery. If the battery is not a genuine removable battery, the management server 300 temporarily or permanently suspends the user's next use. The management server 300 transmits the above-described processing details to the battery exchange station 200 as an inquiry result. Based on the received inquiry result, the exchange control unit 262 performs the above-described control regarding lending when the removable battery 100 is a regular one. Further, if the removable battery 100 is not a regular one, the exchange control unit 262 does not perform control regarding lending, but performs control to notify error information and the like, and to return the stored used removable battery.

Charging control unit 264 controls the charger so that power storage unit 120 is charged to a predetermined charging state (for example, SOC) based on the charging state of power storage unit 120 acquired from removable battery 100 via a signal line. 230. For example, the SOC of power storage unit 120 is sequentially transmitted to charging control unit 264, and charging control unit 264 associates the battery ID and SOC information of removable battery 100 with each other and stores it in storage unit 280 as battery information 284. let

For example, the battery information upload unit 268 counts the number of removable batteries 100 that have been fully charged (charged to a predetermined SOC) (number of charged batteries) at any timing, and stores its own station ID (battery replacement). (identification information for identifying the station 200) and the battery ID are transmitted to the management server 300. The arbitrary timing here includes, for example, the timing at which charging of the removable battery 100 is completed (or charged to a desired SOC), or the timing at which the removable battery 100 is lent. That is, the arbitrary timing may be the timing at which a change occurs in the number of removable batteries or the number of charged batteries stored in the battery exchange station 200. Furthermore, the battery information upload unit 268 may include in the transmitted information the "remaining time required for charging" determined from the charging speed, capacity, etc. for each of the removable batteries 100 that are being charged.

The usage information uploading unit 270 transmits the usage status of the battery exchange station 200 and its own station ID for each user to the management server 300 as usage information at an arbitrary timing. The arbitrary timing here is, for example, the timing when authentication by the authentication unit 245 is permitted and the removable battery is replaced (for example, returned or lent). The usage status may include, for example, the user ID, card ID, battery ID of the returned removable battery 100, battery ID of the lent removable battery 100, date and time of exchange (date and time of use), and the like. Information uploaded at any timing by the battery information upload section 268 or the usage information upload section 270 may be temporarily stored in the storage section 280.

Further, some or all of the functions may be realized by hardware such as LSI, ASIC, FPGA, GPU, etc., or may be realized by collaboration of software and hardware. The above-mentioned program may be stored in advance in a storage device such as an HDD or a flash memory (a storage device equipped with a non-transitory storage medium) of the management server 300, or may be stored in a storage device such as a DVD, CD-ROM, or memory card. It is stored in a removable storage medium, and may be installed in the storage device of the management server 300 by attaching the storage medium (non-transitory storage medium) to a drive device, card slot, or the like.

The storage unit 350 may be realized by the various storage devices described above, or EEPROM, ROM, RAM, or the like. The storage unit 350 stores, for example, a user management table 352, a status table 354, map information 356, a discrepancy information table 358, programs, and other various information.

FIG. 6 is a diagram showing an example of the contents of the user management table 352. The user management table 352 is information in which user IDs and card IDs are associated with passwords, expiration dates, the number of batteries that can be installed, types of usable batteries, status, IDs of batteries being lent, usage history, detailed information, etc. be. For example, a user ID (or card ID) and password are examples of information necessary for user authentication.

The expiration date is set, for example, at the time of registering to use the battery exchange system 1 or at the time of paying the usage fee. The expiration date may be, for example, a fixed period (for example, one year from the time of registration or renewal), and corresponds to the expiration date (vehicle inspection date) specified in the vehicle inspection of the electric vehicle 10 (vehicle continuous inspection specified by the country, etc.). It may also be a set deadline. The number of batteries that can be mounted is the number of batteries that can be mounted on the electric vehicle 10 associated with the card ID. The usable battery type is information such as the type, size, model number, etc. of the removable battery 100 that can be used by the electric vehicle 10 associated with the card ID.

The loaned battery ID is identification information of the removable battery 100 that is being loaned to the electric vehicle 10 associated with the card ID. The usage history is information regarding the past usage history of the battery exchange system 1 that is associated with the user ID and card ID. The usage history includes, for example, information such as the station ID of the battery exchange station 200 used and the date and time of usage. The usage history may include, for example, information uploaded by the usage information upload unit 270. The detailed information includes, for example, personal information such as the user's address, age, and gender acquired at the time of user registration. Further, the detailed information may include performance information and vehicle type information of the electric vehicle 10 associated with the card ID. The performance information of the electric vehicle 10 is, for example, the mileage when one charged removable battery 100 is mounted.

FIG. 7 is a diagram showing an example of the contents of the status table 354. The status table 354 stores information regarding the status of the plurality of battery exchange stations 200 managed by the battery exchange system 1. For example, the status table 354 may include information uploaded by the battery information upload unit 268. For example, the status table 354 includes, for each station ID, the number of charged batteries at the battery exchange station 200 associated with the station ID, the position of the battery exchange station 200, and the battery exchange station 200 specified by the station ID. This information is associated with the business ID of a business that operates a battery replacement service using the service provider ID. If the information to be uploaded includes the remaining time required to charge each removable battery 100 as described above, the status table 354 includes the number of removable batteries 100 being charged and the remaining time for each removable battery 100. information may be added. Further, the status table 354 may include performance information of the removable battery 100. The performance information of the removable battery 100 is, for example, information such as the amount of power when fully charged, the number of times of charging, and the degree of deterioration.

The map information 356 may include, for example, information on the location of the battery exchange station 200 in map coordinates, as well as facility information (POI: Point Of Interest) such as convenience stores, restaurants, accommodation facilities, and various activity facilities. good. The map coordinates are, for example, a coordinate system of three-dimensional coordinates or two-dimensional coordinates measured by a GNSS receiver. Further, the map information 356 may include the position of a road in map coordinates and other road information. Road information includes, for example, road type (for example, general road or expressway), number of lanes, traffic regulation information, installed road signs, legal speed, radius of curvature (or curvature), width, gradient, and unevenness of the road. etc. are included. The map information 356 may be updated at any time by communicating with other devices via the communication unit 310.

FIG. 8 is a diagram showing an example of the contents of the mismatch information table 358. In the discrepancy information table 358, the user ID of the user previously linked to the removable battery 100 returned to the battery exchange station 200 is the user ID of the user who returned the removable battery 100 to the battery exchange station 200. Information indicating that the user IDs do not match (mismatch information) is stored. For example, the discrepancy information table 358 includes at least information about the removable battery 100 returned to the battery exchange station 200 for the return user ID, which is the identification information of the user who returned the removable battery 100 to the battery exchange station 200. This is information associated with a battery ID. The returned user ID may be further associated with the user ID of the user previously linked to the returned removable battery 100. Hereinafter, the removable battery 100 returned to the battery exchange station 200 will be referred to as a returned battery 100, and the removable battery 100 lent from the battery exchange station 200 will be referred to as a rental battery 100. Further, the user who returned the returned battery 100 to the battery exchange station 200 will be referred to as a returning user. Furthermore, a user who is linked in advance to the returned battery 100 will be referred to as a lending user.

The communication unit 310 includes a wired communication device such as a terminal adapter and an Ethernet (registered trademark) communication device, and a wireless communication device such as a Wi-Fi adapter, 3G/LTE, 4G, and Bluetooth, and connects the battery exchange station via the network NW. 200, the electric vehicle 10, etc.

The management unit 320 manages the usage status (including authentication, etc.) of the user when replacing the removable battery 100 shown in FIG. 6. For example, the management unit 320 manages the content of verification authentication information necessary when performing authentication at each battery exchange station 200, and manages the timing of distributing verification authentication information. Further, when there is an authentication inquiry from the battery exchange station 200, the management unit 320 performs authentication using the authentication information acquired along with the inquiry and the user management table 352, and uses the authentication result and the authentication result based on the authentication result. The authentication information for verification may be sent to the battery exchange station 200.

Additionally, the management unit 320 receives requests for new user registration or changes to registered contents, and updates the user management table 352 based on the received information. New registration or changes to registered contents are performed, for example, by a user communicating with the management server 300 from a terminal device or the like. The management unit 320 also updates the status table 354 based on the upload information acquired from the battery exchange station 200. Furthermore, the management unit 320 may manage the billing status and expiration date for each user ID or card ID, for example.

In addition, when the user of the battery exchange station 200 returns the removable battery 100, the management unit 320 checks whether the returning user and the lending user match, and if they do not match, the management unit 320 converts the mismatch information into mismatch information. It is stored and accumulated in the table 358. The management unit 320 confirms the above-mentioned consistency when returning the removable battery 100, and outputs and accumulates discrepancy information as a result of the confirmation, thereby making it easier for returning users and lending users to provide the battery exchange service. Processing can be performed depending on the situation. As a result, the provider of the battery exchange service can restrict the use of the service and charge fees depending on the difference between the returning user and the lending user.

Note that if the battery replacement service is provided through collaboration between a service vendor and a service provider, and the management server 300 is operated by the service vendor, the management unit 320 sends discrepancy information to the service provider's management server (not shown). may be sent. In this case, the service provider's management server can communicate with the management server 300 via the network NW, for example. In this way, by providing the mismatch information to the service provider, the service provider can limit the use of the battery replacement service and charge charges based on the mismatch information. Here, storing the mismatch information in the mismatch information table 358 (that is, saving it in the storage unit 350) and transmitting it to another device (for example, a management server of a service provider) are examples of outputting the mismatch information. be. Further, the management unit 320 is an example of a “lending management unit” and an example of a “charging unit”.

[Processing flow]
The flow of processing executed by the battery exchange system 1 of the embodiment will be described below. Note that the processing executed by the battery exchange system is broadly divided into processing on the battery exchange station 200 side and processing on the management server 300 side. Note that the management server 300 executes authentication processing in conjunction with the processing of the battery exchange station 200, which will be described later, and updates the user management table 352 and status table 354 according to the provision status of the battery exchange service. However, we omit the details here. Below, details of the processing on the battery exchange station 200 side and the processing on the management server 300 side will be explained in order.

[Processing of battery exchange station 200]
FIG. 9 is a flowchart illustrating an example of the flow of processing executed by the battery exchange station 200 of the embodiment. In the example of FIG. 9, the authentication unit 245 receives input of authentication information from the user (step S200). Next, the authentication unit 245 compares the received authentication information with the authentication list 282 stored in the storage unit 280 (step S202), and determines whether matching authentication information is included in the authentication list 282. Determination is made (step S204). If it is determined that matching authentication information does not exist, the authentication unit 245 communicates with the management server 300 using the communication unit 250, transmits the received authentication information to the management server 300, and inquires about the authentication result (step S206 ). Next, the authentication unit 245 determines whether an authentication result corresponding to the inquiry has been obtained (step S208). The authentication result corresponding to the inquiry may include information as to whether the authentication was successful or not, and authentication information for verification in the case of success.

If it is determined in the process of step S204 that matching authentication information exists, or if it is determined that the authentication information corresponding to the inquiry has been acquired in the process of step S208, the authentication unit 245 determines that the usage conditions are satisfied. It is determined whether or not (step S210). The usage conditions here are, for example, that the expiration date for the use of the battery exchange system 1 has not passed, and that the use of the battery exchange system 1 has not been stopped due to unauthorized use.

If it is determined that the usage conditions are met, the authentication unit 245 determines that the user's authentication has been successful, and permits the user to use the service (step S212). In the process of step S212, when the user is permitted to use the slot, the exchange control unit 262 opens the vacant slot 210 and stores the used removable battery 100 to be exchanged. Next, the exchange control unit 262 determines whether the removable battery 100 housed in the open slot is a regular battery (step S214). If it is determined that a regular battery is stored, the exchange control unit 262 opens the slot in which the charged removable battery 100 is stored and lends it out (step S216). Next, the usage information upload unit 270 uploads the usage information to the management server 300 (step S218). Here, when the user returns the removable battery 100 to the battery exchange station 200, the usage information includes the user ID of the returning user and the battery ID of the returned battery 100. Further, when the user receives the loan of the removable battery 100 from the battery exchange station 200, the usage information includes the user ID of the lending user and the battery ID of the loan battery 100.

Furthermore, in the process of step S214, if it is determined that a legitimate battery is not stored, the exchange control unit 262 performs error processing (step S220). In the process of step S220, the exchange control unit 262 causes the display unit 235 to display information indicating that the charged removable battery 100 cannot be lent out because a regular battery is not stored. Further, the slot may be opened so as to take out the used removable battery 100 housed in the empty slot.

In addition, if it is determined that the authentication information corresponding to the inquiry has not been acquired in the process of step S208, or if it is determined that the usage conditions are not satisfied in the process of step S210, the battery may be replaced based on the user authentication result. The user is notified that the station 200 is unavailable (step S222). Thereby, the processing of this flowchart ends.

[Processing of management server 300]
FIG. 10 is a flowchart illustrating an example of the flow of processing executed by the management server 300 of the embodiment. In the example of FIG. 10, the series of processing flows is started, for example, in response to the management unit 320 receiving usage information from the battery exchange station 200 (step S301). Subsequently, the management unit 320 recognizes the returning user and the returned battery 100 based on the received usage information, and also recognizes the lending user linked in advance to the returned battery 100 (step S302). Subsequently, the management unit 320 determines whether the recognized user ID of the returning user matches the recognized user ID of the lending user (step S303).

Here, if it is determined that the user ID of the returning user matches the user ID of the lending user, there is no need to output the mismatch information, so the subsequent processing is skipped and the series of processing flows is ended. On the other hand, if it is determined that the user ID of the returning user does not match the user ID of the lending user, then the management unit 320 stores the recognized user ID of the returning user as a predetermined specific user ID. It is determined whether the user ID matches the user ID of the user (hereinafter referred to as a specific user) (step S304). The specific user is a user who is preset as a returning user who does not need to output discrepancy information even if the returning user is different from the lending user. The specific user may be arbitrarily set by the service provider. In this embodiment, it is assumed that a service person receives a request from a user, acquires a charged removable battery 100 from the battery exchange station 200 on behalf of the user, and delivers it to the user who made the request. Service personnel will be discussed later.

Here, if it is determined that the user ID of the returning user matches the user ID of the specific user, the management unit 320 skips the subsequent processing and ends the series of processing flows. On the other hand, if it is determined that the user ID of the returning user does not match the user ID of the specific user, the management unit 320 subsequently outputs mismatch information (step S305). For example, the management unit 320 stores the mismatch information in the mismatch information table 358. After outputting the mismatch information, the management unit 320 then calculates the current accumulated amount of mismatch information (step S306), and determines whether the calculated accumulated amount of mismatch information is equal to or greater than a threshold ( Step S307).

Here, if it is determined that the accumulated amount of discrepancy information is less than the threshold value, the management unit 320 determines that there is no need to make special charges to the user at that point, and skips the subsequent processing and continues the processing flow. end. On the other hand, if it is determined that the accumulated usage of the mismatch information is equal to or greater than the threshold value, the management unit 320 charges the user a special charge (step S308), and ends the series of processing flows.

Here, the special charge is a charge to the user when the accumulated amount of mismatch information exceeds a threshold value. For example, in general, in the above-mentioned battery exchange service, if the lending user and the returning user are different, it is assumed that the rented removable battery 100 is not used by an authorized user, or the service This is not preferable because it may be assumed that the usage fee will not necessarily be charged to the user who uses the removable battery 100. Therefore, in such a case, it is typically assumed that a violation fee will be charged as a special charge. In this case, the special charge may be charged to the returning user, may be charged to the lending user who has lent the returned battery 100, or may be charged at a predetermined rate. It is also possible to charge both parties.

FIG. 11 is a diagram showing an example of a situation in which the returning user becomes a service person (an example of a specific user). In the example of FIG. 11, the user U is the driver of the electric vehicle M. The electric vehicle M is driven by a removable battery 100 as a power source, and the situation in the example shown in FIG. It represents the situation.

On the other hand, service center C is a business office of a business that provides various support services to vehicle drivers. For example, support services may dispatch workers to the vehicle site to repair the vehicle, or if it is difficult to respond on-site, a vehicle transport vehicle or tow vehicle may be dispatched to the site to repair the vehicle. This service involves transporting the vehicle to a repair shop, etc. In the example situation of FIG. 11, the service center C dispatches a service person with a charged removable battery 100 to the site of the vehicle M, and provides the user U with a battery replacement service. Further, the battery exchange station 200S is a battery exchange station 200 used by a service person when returning the removable battery 100 with zero remaining capacity collected from the user U. The battery exchange station 200S may be the battery exchange station 200 that lent the removable battery 100M to the user U, or may be any other battery exchange station 200.

In such a situation, the user U requests the service center C to replace the removable battery 100M using the user terminal device T such as a smartphone or a mobile phone (step S41: rescue request). At this time, the user terminal device T may notify the service center C of the location where the vehicle M is stopped by transmitting its own location information. Upon receiving a rescue request from user U, service center C dispatches a serviceman SM with a replacement removable battery 100R1 (fully charged) to the site where vehicle M is stopped (step S42: rescue instruction). . After receiving the rescue instruction, the service man SM heads to the place where the vehicle M is stopped with the removable battery 100R1 (step S43), and when he arrives at the place where the vehicle M is stopped, the serviceman SM carries the transported removable battery 100R1 to the place where the remaining battery is zero. The battery is replaced with a removable battery 100M (step S44). This allows the user U to resume driving the own vehicle M.

After the serviceman SM replaces the removable battery 100 at the stop site, he then heads to the battery replacement station 200S with the removable battery 100M collected from the user U (step S45). When the serviceman SM arrives at the battery exchange station 200S, he performs authentication using the user card, returns the removable battery 100M collected from the user U to the battery exchange station 200S (step S46), and also returns the charged battery to the battery exchange station 200S. A new removable battery 100R2 is lent (step S47). The serviceman SM returns to the service center C with the new detachable battery 100R2 that was lent to him (step S48).

In such a support service, when the serviceman SM returns the removable battery 100M to the battery exchange station 200S, if the serviceman SM has already been registered as a specific user in the management server 300, the management unit 320 , even if the user ID of the serviceman SM does not match the user ID associated with the removable battery M (that is, the user ID of the user U in the example of FIG. 11), the battery exchange station 200S The customer is instructed to lend a new removable battery 100 to the customer. This allows the serviceman SM to return the removable battery 100M collected from the user U to the battery exchange station 200 on behalf of the user.

Furthermore, if the serviceman SM has been registered in advance as a specific user, the management unit 320 does not output discrepancy information regarding the return of the removable battery 100M by the serviceman SM. As a result, it is possible to prevent inconsistent information from being accumulated for specific users such as service personnel, so it is possible to prevent the accumulation of inconsistent information for specific users such as service personnel. can be monitored for consistency.

Furthermore, when the user U who has been loaned a new removable battery 100R1 through such a support service returns the removable battery 100R1 to the battery exchange station 200S after using the removable battery 100R1, the management unit 320 If it is recognized that the returned removable battery 100R1 was lent based on a rescue request, no discrepancy information regarding the return of the removable battery 100R1 is output, and a new removable battery is sent to the battery exchange station 200S. An instruction is given to lend out the battery 100. For example, whether or not the removable battery 100R1 has been lent based on a rescue request can be determined by checking whether information indicating that fact (hereinafter referred to as a rescue flag) is recorded in the storage unit 140 of the removable battery 100R1. It can be determined whether or not. In this case, the serviceman SM may record the rescue flag in the storage unit 140 of the removable battery 100R1 to be lent to the user U, and then lend the removable battery 100R1 to the user U. When the removable battery 100R1 is returned, the battery exchange station 200S reads the battery information including the rescue flag and sends it to the management server 300, so that the management unit 320 can confirm that the removable battery 100R1 was lent based on a rescue request. It can be recognized that

Note that the form of support service provision described in FIG. 11 is an example, and is not limited to this. Specifically, the support service may be provided in any form as long as it is possible to prevent the output of discrepancy information for a specific user. For example, in the example of FIG. 11, when the serviceman SM hands over the replacement removable battery 100R1 to the user U, the rescue flag may be exchanged directly between the user U and the serviceman SM. . For example, the rescue flag may be transmitted from the serviceman terminal device owned by the serviceman SM to the user terminal device T when the removable battery 100R1 is handed over. In this case, when the user U returns the removable battery 100R1, by making the battery exchange station 200 to which the battery is returned recognize the rescue flag, it is possible to prevent discrepancy information from being recorded regarding the return. The rescue flag may be transmitted and received by short-range wireless communication between terminals, by communication via a network NW, or by information displayed on a serviceman terminal device (for example, a bar code or QR code). (registered trademark) etc.) may be exchanged by the user terminal device T reading the information.

According to the battery exchange system 1 of the embodiment configured as described above, the authentication unit 245 authenticates the user, and the charged removable battery 100 is lent to the authenticated user or At the battery exchange station 200 that collects used removable batteries 100 from users, and when renting out the removable batteries 100, the identification information of the user to be lent and the identification information of the removable battery 100 to be lent are provided. and a management unit 320 that manages the linked battery, wherein the management unit 320 sets the identification information of the user who returned the removable battery 100 to the identification information of the user linked in advance to the returned removable battery 100. If they do not match, output mismatch information including the identification information of the user who returned the removable battery 100 and the identification information of the returned removable battery 100, and then return the removable battery 100 to the battery exchange station 200. By having the user lend out a new removable battery 100, it is possible to improve the convenience of the battery sharing service and to suppress unauthorized use of the battery.

[Modified example]
In the embodiment described above, among the functions of the management unit 320 provided in the management server 300, when lending out the removable battery 100, the identification information of the user to be lent and the identification information of the removable battery 100 to be lent are The function of linking and managing and the function of outputting and managing discrepancy information may be provided on the battery exchange station 200 side.

In the embodiment described above, when the authentication information input by the user is not stored in the authentication list 282 stored in the storage unit 280, the battery exchange station 200 makes an inquiry to the management server 300 about the authentication information. However, due to a disaster such as a typhoon or an earthquake, or a system error, communication between the battery exchange station 200 and the management server 300 may be disabled, and inquiries to the management server 300 may not be made. Therefore, when making an inquiry to the management server 300 for user authentication information, the battery exchange station 200 determines whether or not the authentication was successful if communication with the management server 300 is not possible for a predetermined period of time or longer, and if predetermined conditions are met. Regardless of whether this is the case, the charged removable battery 100 may be lent out. If predetermined conditions are met, for example, if the authentication information input by the user for user authentication matches the registrant information of the battery exchange system 1, or if the authentication information is This includes cases where a flag that allows lending is included. As a result, even if proper user authentication cannot be performed due to a communication error or the like, the removable battery 100 can be lent out without waiting for communication to be restored.

Note that when renting out the removable battery 100 using the method described above, the exchange control unit 262 stores authentication information from the user in the storage unit 280, and sends the authentication information to the management server 300 after communication is restored. The storage unit 280 is queried. If matching authentication information exists in the user management table 352 and the usage conditions are met, the management server 300 updates the usage history for that user. On the other hand, if there is no matching authentication information in the user management table 352, or if the usage conditions are not met, the management server 300 stops the user from using the service from next time onwards. In this case, the management server 300 may set the status of the user management table 352 to "suspended" and prohibit future use of the removable battery.
