Further, for unauthorized use, the detachable battery 100 lent to the first user may be lent again to a third party other than the first user, or replaced with a detachable battery mounted on a third party's electric vehicle. Aspects may be included. Further, the unauthorized use may include a mode of exchanging a genuine product for a non-genuine product. The details of the function of the fraud determination unit 268 will be described later.

For example, the upload unit 270 counts the number of removable batteries 100 (the number of charged removable batteries) that have been charged (charged to a predetermined SOC) at an arbitrary timing, and owns the device ID (battery replacement). It is transmitted to the management server 300 together with the identification information) that identifies the device 200 and the battery ID. The arbitrary timing here includes, for example, the timing at which the detachable battery 100 has been charged (or has been charged to a desired SOC), or the timing at which the detachable battery 100 has been rented. That is, the arbitrary timing may be the timing at which the number of detachable batteries stored in the battery exchange device 200 and the number of charged detachable batteries fluctuate. Further, the upload unit 270 may include the "remaining time required for charging" obtained from the charging speed, the capacity, and the like for each of the detachable batteries 100 in the middle of charging in the information to be transmitted.

Further, the upload unit 270 transmits the usage status of the battery replacement device 200 for each user and its own device ID as usage information to the management server 300 at an arbitrary timing. The arbitrary timing here is, for example, the timing at which authentication by the authentication unit 245 is permitted and the removable battery is replaced (for example, returned or rented). The usage status may include, for example, a user ID and a card ID, a battery ID of the returned removable battery 100, a battery ID of the rented removable battery 100, a replacement date and time (usage date and time), and the like.

Further, the upload unit 270 may transmit, for example, the information acquired by the acquisition unit 264 or the information determined by the fraud determination unit 268 to the management server 300. The information uploaded by the upload unit 270 at an arbitrary timing may be temporarily stored in the exchange device side storage unit 280.

Communicates with the switching device 200, the electric vehicle 10, and the like.

The management unit 320 manages the usage status (including authentication) of the user at the time of replacement of the removable battery 100 shown in FIG. For example, the management unit 320 manages the content of the verification authentication information required for authentication in each battery replacement device 200, and manages the timing of providing the verification authentication information. Further, when the battery replacement device 200 receives an authentication inquiry, the management unit 320 performs authentication using the authentication information acquired together with the inquiry and the user management table 352, and is based on the authentication result and the authentication result. The verification authentication information may be transmitted to the battery exchange device 200.

Further, the management unit 320 receives a new registration of the user and a request for changing the registered contents, and updates the user management table 352 based on the received information. New registration and change of registration contents are performed, for example, by communicating with the management server 300 from a terminal device (not shown) or the like used by the user. Further, the management unit 320 updates the status table 354 based on the upload information acquired from the battery replacement device 200. Further, the management unit 320 may manage, for example, the billing status and the expiration date for each user ID or card ID.

Further, the management unit 320 updates the user management table 352, the status table 354, the map information 356, and the vehicle-specific electricity cost table 358 based on the information uploaded by the upload unit 270 and the information acquired from the external server or the like. do. For example, when the information uploaded by the upload unit 270 includes information regarding the determination result of unauthorized use, the management unit 320 updates the user management table 352 based on the determination result. Specifically, for example, when it is determined that a certain user has illegally used the user, the management unit 320 is associated with the user ID and the card ID of the user included in the user management table 352. Update the status such as suspending the use or canceling the suspension by paying a fine.

The providing unit 330 generates the verification authentication information (authentication list) based on the user management table 352, and provides the generated verification authentication information to the battery exchange device 200. For example, the provider 330 distributes the verification authentication information to some of the battery replacement devices among the plurality of battery replacement devices, based on the information about the battery obtained from the battery replacement device 200 and the like. The providing unit 330 estimates, for example, the movable distance (for example, the cruising range) of the electric vehicle 10 used by the user based on the position information of the battery switching device 200 used by the user, and the estimated movable distance. Based on the distance, the collation authentication information is provided to the movable range (for example, the cruising range) of the electric vehicle 10 starting from the battery exchange device 200. Further, the providing unit 330 may provide the battery exchange device 200 with information regarding the user ID and the card ID whose status is suspended.

Further, the providing unit 330 inquires about the position and usage status (number of charged removable batteries 100) of the battery replacement device 200 by the electric vehicle 10 or the terminal device (for example, a smartphone or tablet terminal) used by the user. If so, the state table 354 is referred to based on the position information acquired from the electric vehicle 10 or the terminal, and the battery replacement device 200 existing within a predetermined range from the position of the electric vehicle 10 or the terminal device is acquired.

[About fraud judgment]
Next, the fraud determination process in the fraud determination unit 268 of the battery replacement device 200 will be specifically described. Hereinafter, each of several determination patterns will be described. Further, in the following example, after the user has been successfully authenticated by the authentication unit 245 and the used removable battery 100 has been returned, and before the charged removable battery 100 has been rented out. It is assumed that fraud determination processing is performed. Further, the fraud determination process shown below shall be performed for each of the returned removable batteries 100.

<First judgment pattern>
The first determination pattern is to determine whether or not the detachable battery 100 has been illegally used based on the information of the odometer of the electric vehicle 10 obtained from the detachable battery 100. FIG. 9 is a diagram for explaining the first determination pattern. In the example of FIG. 9, the value of the odometer [Km] acquired from the electric vehicle 10 at predetermined time intervals from the time when the removable battery 100 is rented out from the battery exchange device 200 to the time when the removable battery 100 is returned is shown. These pieces of information are information stored in the storage unit 140. Further, in the example of FIG. 9, the value of the odometer corresponding to the number of acquisitions (1 to 5 times) is shown, but the number of acquisitions is not limited to this.

Since the odometer of the electric vehicle 10 is the integrated mileage after the electric vehicle 10 is manufactured (completed), the distance does not decrease in the same vehicle. Therefore, when the value of the odometer acquired from the electric vehicle 10 continuously increases according to the mileage at predetermined time intervals, the fraud determination unit 268 illegally uses it between the time it is rented and the time it is returned. It is determined that it has not been done. On the other hand, when the value of the odometer is smaller than the previous value, the fraud determination unit 268 determines that the detachable battery 100 has been illegally used between the time of lending and the time of returning.

In the example of FIG. 9, the value of the odometer from the first time to the third time is continuously increasing, while the value of the odometer is decreasing at the time of the fourth acquisition. In this case, the fraud determination unit 268 determines that the detachable battery 100 has been illegally used.

According to the first determination pattern described above, it is possible to easily grasp the use of the detachable battery 100 in a plurality of vehicles. Therefore, unauthorized use can be determined more appropriately.

<Second judgment pattern>
In the second determination pattern, in addition to the first determination pattern, even when the value of the odometer continues to increase, if the amount of change is equal to or greater than the threshold value, the removable battery 100 is illegally used. It is determined that it has been done. FIG. 10 is a diagram for explaining the second determination pattern. In the example of FIG. 10, the value of the odometer acquired from the electric vehicle 10 at predetermined time intervals after the detachable battery is rented is shown as in FIG. 9. When the fraud determination unit 268 continuously increases (or does not decrease) the value of the odometer from the first to the fifth time, the acquisition unit 264 informs the acquisition unit 264 based on the user ID and the card ID at the time of authentication. The management server 300 is inquired about the past usage history of the detachable battery 100, and the management server 300 is made to acquire the usage history. The fraud determination unit 268 derives the average or maximum value of the past increase in the odometer based on the usage state of the user as a threshold value based on the acquired usage history. The threshold value may include an allowable range (margin) with respect to the average value or the maximum value. Then, the fraud determination unit 268 determines that the detachable battery 100 is not illegally used when the increase amount is not equal to or more than the threshold value, and determines that the detachable battery 100 is illegally used when the increase amount is equal to or more than the threshold value.

Here, it is assumed that the threshold value is derived as 30 [km]. In the example of FIG. 10, the amount of change in the value of the odometer from the second time to the third time is 40 [km]. In this case, the fraud determination unit 268 determines that the detachable battery 100 has been illegally used.

As described above, according to the second determination pattern, even when the value of the odometer continuously increases according to the mileage, the threshold value based on the usage history of the removable battery 100 is used more appropriately. Unauthorized use can be determined.

<Third judgment pattern>
The third determination pattern determines whether or not the removable battery 100 has been illegally used, based on the vehicle type information in addition to the first and second determination patterns. FIG. 11 is a diagram for explaining the third determination pattern. In the example of FIG. 11, the value of the odometer acquired every time the power consumption by the power storage unit 110 exceeds the first threshold value (for example, 1 [kWh]) after the detachable battery 100 is rented is shown.

In the third determination pattern, the acquisition unit 264 acquires vehicle type information of the electric vehicle 10 to which the removable battery is mounted from the storage unit 140 of the removable battery 100, and the electricity cost information associated with the acquired vehicle type information. Is inquired to the management server 300, and electricity cost information is acquired from the management server 300. The fraud determination unit 268 determines the difference between the mileage per 1 [kWh] of the detachable battery 100 acquired from the management server 300 as electricity cost information and the difference in the odometer value between the number of consecutive acquisitions acquired from the detachable battery 100 ( (Measured mileage) is compared, and if the difference is less than a predetermined value, it is determined that the vehicle has not been illegally used, and if it is greater than or equal to the predetermined value, it is determined that the vehicle has been illegally used. In the third determination pattern, the above-mentioned actually measured mileage corresponds to the actually measured electricity cost information. The above-mentioned predetermined value may be a fixed value, and the vehicle type information of the electric vehicle 10 (for example, large or small, special vehicle, etc.), the running state (for example, whether or not the vehicle is running on a slope or a highway, and whether or not air conditioning is provided). It may be a variable value according to (whether or not).

Here, it is assumed that the mileage per 1 [kWh] of the removable battery 100 with respect to the vehicle type information is 3 [km], and the predetermined value is 5 [km]. In the example of FIG. 11, the difference between the values of the third and fourth odometers is 14 [km], and the difference (14-3) from the electricity cost information is 9 [km], so that it is equal to or more than a predetermined value. In this case, the fraud determination unit 268 determines that the detachable battery 100 has been illegally used.

As described above, according to the third determination pattern, it is possible to more appropriately determine whether or not the removable battery 100 has been illegally used, taking into account vehicle type information (more specifically, electricity cost information). can. In addition, if a different rate plan is set for each vehicle type, there is a high possibility that the removable battery 100 rented out with a low rate plan will be illegally used for a vehicle with a high rate plan, so it is illegal including vehicle type information. By making the judgment, it is possible to more appropriately judge the unauthorized use.

In the third determination pattern, it was determined whether or not the information was illegally used by using the electricity cost information corresponding to the vehicle type information, but instead of (or in addition to) the vehicle type information, each vehicle ID or card ID was used. The above-mentioned determination process may be performed using the electricity cost information and the like. In this case, the management server 300 performs statistical processing in advance from the usage history for each vehicle ID or card ID, derives electricity cost information, and stores it in the server-side storage unit 350. Further, when the management server 300 inquires about the electricity cost information based on the vehicle ID or the card ID from the battery exchange device 200, the management server 300 receives the electricity cost information corresponding to the vehicle ID and the card ID from the information stored in the server side storage unit 350. To the battery replacement device 200. As a result, it is possible to more appropriately determine unauthorized use for each user based on the electricity cost information derived based on the usage status of each user.

<Fourth judgment pattern>
The fourth determination pattern is different from the third determination pattern in that it does not include electricity cost information and determines whether or not the removable battery 100 has been illegally used based on the vehicle type information. In this case, the acquisition unit 264 acquires vehicle type information of the electric vehicle 10 to which the detachable battery 100 is mounted from the storage unit 140 of the detachable battery 100. Further, the acquisition unit 264 inquires the management server 300 about the vehicle type information based on the card ID of the user card read from the reading unit 240, and acquires the vehicle type information associated with the card ID from the user management table 352. do. The fraud determination unit 268 determines that the vehicle model information acquired from the storage unit 140 of the removable battery 100 and the vehicle model information acquired from the management server 300 based on the card ID are not illegally used. If they are different, it is determined that they have been abused.

Further, in the fourth determination pattern, the vehicle ID may be used instead of (or in addition to) the vehicle type information. When the vehicle ID is used, for example, the acquisition unit 264 acquires the vehicle ID of the electric vehicle 10 to which the detachable battery 100 is mounted from the storage unit 140 of the removable battery 100, and is read from the user card by the reading unit 240. Obtain the vehicle ID. The fraud determination unit 268 determines that both vehicle IDs are not fraudulently used when they are the same, and determines that they are fraudulently used when they are different. By using the vehicle ID, it is possible to specify and compare the electric vehicle 10 rather than using the vehicle type information.

As described above, according to the fourth determination pattern, it is possible to more appropriately determine whether or not the removable battery 100 has been illegally used by using the vehicle type information without including the electricity cost information. In addition, if a different rate plan is set for each vehicle type, there is a high possibility that the removable battery 100 rented out with a low rate plan will be illegally used for a vehicle with a high rate plan, so it is illegal including vehicle type information. By making the judgment, it is possible to more appropriately judge the unauthorized use.

<Fifth judgment pattern>
In the fifth determination pattern, instead of (or in addition to) the first to fourth determination patterns, the battery ID of the detachable battery 100 at the time of rental and the battery ID of the detachable battery 100 at the time of return are collated. By doing so, it is determined whether or not the battery has been illegally used.

In the fifth determination pattern, the acquisition unit 264 inquires the management server 300 about the battery ID of the detachable battery 100 at the time of the previous lending, based on the user ID and the card ID acquired at the time of authentication. When the management server 300 receives an inquiry from the battery switching device 200, the management server 300 refers to the user ID and the card ID of the user management table 352 by using the user ID and the card ID, and the user in the case of matching. Acquires information on the rented battery ID associated with the ID and the card ID. Then, the acquired information on the rented battery ID is transmitted to the inquired battery replacement device 200.

The fraud determination unit 268 compares the rented battery ID acquired from the management server 300 with the battery ID at the time of return, and determines that the battery ID at the time of return is not illegally used when the battery ID at the time of return is included in the rented battery ID. However, if the battery ID at the time of return is not included in the rented battery ID, it is determined that the battery is being used illegally.

As described above, according to the fifth determination pattern, the unauthorized use of the detachable battery 100 can be determined by comparing the battery IDs at the time of lending and at the time of returning. In the fifth determination pattern, the first user performs only when the removable battery 100 is rented and returned, and the actual use is performed by a third party electric vehicle 10 other than the first user. , It cannot be determined that it has been abused. Therefore, the accuracy of the determination result can be improved by executing the fifth determination pattern in combination of at least one of the first to fourth determination patterns described above.

When it is determined by the fraud determination unit 268 that the detachable battery 100 has been illegally used, the exchange control unit 262 causes the display unit 235 to display information (warning information) indicating that the detachable battery 100 has been determined to be illegally used. Further, the exchange control unit 262 controls to temporarily or permanently prohibit the lending of the charged detachable battery 100 and to give the user a predetermined penalty such as paying a fine. As a result, unauthorized use of the detachable battery 100 can be suppressed. Further, the exchange control unit 262 displays on the display unit 235 that the above-mentioned penalty is given when the user initially uses the battery exchange device 200 or rents out the detachable battery 100, and notifies the user. Therefore, the deterrent effect of unauthorized use can be further improved.

[Processing flow]
Hereinafter, the flow of processing executed by the battery replacement device 200 of the embodiment will be described. In the following, the explanation will mainly focus on the fraud determination process after the battery is returned (and before it is rented). FIG. 12 is a flowchart showing an example of a processing flow executed by the battery switching device 200 of the embodiment.

In the example of FIG. 12, the acquisition unit 264 acquires an odometer value (information about the vehicle) acquired from the stored unit 140 of the returned removable battery 100 from the electric vehicle 10 on which the removable battery 100 is mounted at a predetermined timing. (Example) is acquired (step S100). Next, the fraud determination unit 268 determines, for example, whether or not the value of the odometer acquired in a predetermined cycle is continuously increasing (step S102). If it is determined that the battery is continuously increasing, the acquisition unit 264 acquires the usage history of the detachable battery 100 (step S104). Next, the fraud determination unit 268 determines whether or not the amount of increase in the value of the odometer is less than the threshold value derived based on the usage history of the removable battery 100 (step S106).

When it is determined that the amount of increase in the value of the odometer is less than the threshold value, the acquisition unit 264 acquires the electricity cost information corresponding to the vehicle type (an example of information about the vehicle) acquired from the detachable battery 100 from the management server 300 ( Step S108). Next, the fraud determination unit 268 determines whether or not the difference between the actually measured electricity cost information obtained from the value of the odometer and the electricity cost information acquired from the management server 300 is less than a predetermined value (step S110). When it is determined that the difference between the actually measured electricity cost information and the electricity cost information acquired from the management server 300 is less than the threshold value, the fraud determination unit 268 determines that the detachable battery 100 is not illegally used (step S112). Next, the exchange control unit 262 controls to rent out the charged detachable battery 100 (step S114).

Further, in the process of step S102, when it is determined that the value of the odometer acquired at a predetermined timing does not continuously increase, the amount of increase of the odometer value in the process of step S106 is not less than the threshold value (greater than or equal to the threshold value). If it is determined that the difference between the actually measured electricity cost information and the electricity cost information is not less than a predetermined value (is more than a predetermined value) in the process of step S110, the fraud determination unit 268 is attached / detached. It is determined that the formula battery 100 has been illegally used (step S116). Next, the exchange control unit 262 displays information indicating that it has been determined to be illegally used on the display unit 235 and notifies the user (step S118), and uses the battery exchange service for the user. (Step S120). As a result, the processing of this flowchart ends.

[Modification example]
