The vehicle 150 further includes: a communication unit 102 that communicates with the storage battery 250 stored in the battery storage unit 101; a comparison unit 127 that compares the authentication key; and a deletion unit 129 that sends a deletion signal for deleting the old authentication key via the communication unit 102 To the battery 250 and the display unit 131, an arbitrary message, such as a message of an authentication error, is displayed.

The authentication key storage unit 124 stores an authentication key. The authentication key storage unit 124 stores a third authentication key for the vehicle 150 that can be mutually authenticated with the first authentication key for the storage battery 250 written in the storage battery 250 and the second authentication key for the management device 450.

When the storage unit 250 is stored in the storage unit 101, the communication unit 102 reads the first authentication key written in the storage unit 250 through wired communication or wireless communication, and outputs it to the comparison unit 127.

When the first authentication key is input from the communication unit 102, the collation unit 127 obtains the third authentication key stored in the authentication key storage unit 124, and collates the first authentication key and the third authentication key. When the first authentication key and the third authentication key can mutually authenticate each other, the collation unit 127 outputs the authentication information indicating the meaning to the deletion unit 129. When the first authentication key and the third authentication key cannot mutually authenticate each other, the collation unit 127 outputs an instruction to display a message indicating an authentication error to the display unit 131 and displays the message.

When the deletion unit 129 has input the authentication information from the collation unit 127, the deletion unit 129 causes the communication unit 102 to read the new third authentication key written in the battery 250 stored in the battery storage unit 101 and stores the new third authentication key in the authentication key storage unit 124. Furthermore, the deletion unit 129 deletes the old third authentication key stored in the authentication key storage unit 124. Furthermore, the deletion unit 129 deletes the old first authentication key written in the battery 250 via the communication unit 102. In addition, a new first authentication key is also written in the battery 250, but the deletion unit 129 selectively does not delete the new first authentication key.

FIG. 22 is a block diagram of the battery 250. The storage unit 210 of the battery 250 includes an authentication key storage unit 218 that stores an authentication key. The authentication key storage unit 218 stores a first authentication key and a third authentication key. The battery 250 includes a communication unit 230 that communicates with the station 300 and the vehicle 150.

When the communication unit 230 receives an instruction to read and write the information stored in the storage unit 210 from the management device 450 via the site 300, the communication unit 230 reads and writes the information according to the instruction, and reads the read information. Information is sent to site 300. In addition, the communication section 230 is still When the deletion signal is received from the vehicle 150, the old first authentication key stored in the authentication key storage unit 218 is deleted in accordance with the deletion signal, for example. In addition, the communication unit 230 outputs an instruction to the deterioration display unit 240 when receiving an instruction to display the current deterioration state of the battery 250 from the site 300.

FIG. 23 is a block diagram of the management device 450. The storage unit 420 of the management device 450 includes an authentication key storage unit 430 that stores an authentication key. The authentication key storage unit 430 stores, for example, a second authentication key.

The management device 450 includes a collation unit 441 that collates the authentication key, a generation unit 443 that generates a new authentication key, and a deletion unit 445 that deletes the old authentication key stored in the authentication key storage unit 430.

The collating unit 441 obtains the second authentication key stored in the authentication key storage unit 430 when the first authentication key and the third authentication key are input from the reading unit 401, and compares the first authentication key, the third authentication key, and the second authentication key, respectively. Authentication key. When the first authentication key, the third authentication key, and the second authentication key can mutually authenticate each other, the collation unit 441 outputs authentication information indicating the meaning to the generation unit 443. When at least one of the first authentication key, the third authentication key, and the second authentication key cannot mutually authenticate, the collation unit 441 outputs an instruction to display a message indicating an authentication error to the display unit 307 of the site 300, and causes the The message is displayed. This message may also indicate which authentication key group cannot mutually authenticate each other.

The generation unit 443 generates three new authentication keys capable of mutual authentication when the authentication information is input from the collation unit 441. Specifically, the generating unit 443 generates a new second authentication key, a new first authentication key, and a new third authentication key. The generating unit 443 outputs the new second authentication key to the deleting unit 445, and outputs the new first authentication key and the new third authentication key to the writing unit 417 together with the old first authentication key.

When a new second authentication key is input from the generating unit 443, the deleting unit 445 stores the new second authentication key in the authentication key storage unit 430, and deletes the second authentication key previously stored in the authentication key storage unit 430, that is, Old 2nd authentication key. The process of storing the new second authentication key in the authentication key storage unit 430 and the process of deleting the old second authentication key stored in the authentication key storage unit 430 may be performed in a predetermined order or in a different order. .

As described above, the authentication key existing before the authentication key is generated by the generating unit 443 may be referred to as an old authentication key, and the authentication key generated by the generating unit 443 may be referred to as a new authentication key.

When the writing unit 417 inputs the new first authentication key and the new third authentication key generated by the generating unit 443 together with the old first authentication key, the user who has loaned the site 300 to the battery 250 is returned. The instruction written in the battery 250 of 60 is output to the station 300.

For the purpose of clarity, the management device 450 in this embodiment does not include the presentation unit 405, the management unit 419, the loan processing unit 407, and the location output of the management device 400 according to the first embodiment shown in FIG. The unit 412, the excellent return reward unit 414, and the good use reward unit 416 do not include the ID list storage unit 429, the related information storage unit 431, the address distance storage unit 433, and the area information storage included in the storage unit 420 of the management device 400 The unit 435 and the reward information storage unit 437. However, the management device 450 in the present embodiment may include a part or all of these configurations included in the management device 400 according to the first embodiment.

FIG. 24 is a flowchart according to the fifth embodiment. Description of the flow of FIG. 24. The battery 250 used in the own vehicle 150 is returned to the site 300 by the specific user 60. beginning.

When the battery 250 is mounted on the vehicle 150, the vehicle 150 writes the third authentication key into the battery 250 in advance (S101). When the battery 250 is removed from the vehicle 150 (S103) and returned to the station 300, the management device 450 reads the first authentication key and the third authentication key written in the battery 250 via the station 300 (S105).

The management device 450 compares each of the read first authentication key and the third authentication key with the second authentication key held by the management device 450 (S107).

In the case where any of the first authentication key and the third authentication key and the second authentication key cannot mutually authenticate (S109: NO), the display instruction of the authentication error is output to the site 300 (S111), and the flow is End. When any of the first authentication key and the third authentication key and the second authentication key can mutually authenticate (S109: YES), the information of the battery 250 returned to the site 300 is read (S112). In addition, when mutual authentication cannot be performed, the station 300 does not read the information of the battery 250.

The management device 450 generates a new first authentication key, a new second authentication key, and a new third authentication key (S113), deletes the old second authentication key stored in the management device 450, and stores a new second authentication key ( S115).

The management device 450 writes the new first authentication key and the new third authentication key together with the old first authentication key to the battery 250 lent to the user 60 to perform the lending process to the site 300 (S117 ). In this case, even if the other first authentication key and third authentication key are stored in advance in the battery 250 to be lent, the first authentication key and the third authentication key are updated. In addition, the management device 450 preferably lends the charged battery 250.

When the user 60 installs the battery 250 loaned from the site 300 to the vehicle 150 (S119), the vehicle 150 reads the old first authentication key from the battery 250 (S121), and holds the old first authentication key with itself The old third authentication key is compared (S123).

In a case where the old first authentication key and the old third authentication key cannot mutually authenticate (S125: NO), the vehicle 150 displays an authentication error message (S127), and the flow ends. When the first authentication key and the third authentication key can mutually authenticate (S125: Yes), the vehicle 150 reads the new third authentication key from the battery 250 and stores it (S129), and deletes the old one held by itself Third authentication key (S131). At the same time, the vehicle 150 sends a delete signal to the battery 250 (S133), deletes the old first authentication key and the new third authentication key written in the battery 250 (S135), and the process ends. As described above, the flow of FIG. 24 is repeatedly executed while each device such as the management device 450 is operating.

In the above-mentioned embodiment, in S125, the vehicle 150 may arbitrarily perform writing processing and reading processing of information for the storage battery 250 on the condition that the authentication key can be mutually authenticated with the storage battery 250 on loan.

As described above, according to the management system 19 of this embodiment, even if a malicious third party illegally obtains the first authentication key from the battery 250 and writes it into a low-priced counterfeit with no guaranteed quality, the first authentication is stored. The real battery 250 of the secret key has been updated to a new authentication key when it is returned to the site 300, so the counterfeit product authentication will not succeed. Therefore, this counterfeit cannot be applied to any of the management device 450 and the vehicle 150. As a result, it is possible to prevent the user 60 from inadvertently borrowing a counterfeit product from the power station 300, and it is also possible to prevent the counterfeit product, which is considered a genuine battery 250, from being lent, and is dissatisfied with, for example, low horsepower driving and severe battery consumption.

In addition, according to the above configuration, if the authentication key cannot be mutually authenticated with the stored battery 250, neither the management device 450 nor the vehicle 150 performs the writing process and the reading process of the information for the battery 250, so that the information can also be prevented. Illegal outflow via imitation.

FIG. 25 is a schematic diagram of a management system 21 according to the sixth embodiment. In the management system 21, the same configurations as those of the management system 19 of the fifth embodiment are assigned the same reference numerals, and descriptions thereof are omitted. As shown in FIG. 25, in the management system 21, the vehicle 160, the battery 250, and the management device 460 communicate with each other via a communication network 40.

FIG. 26 is a block diagram of the vehicle 160. The vehicle 160 is different in a point that does not include the deletion unit 129 and a point in which the communication unit 162 communicates with the management device 460. The same configuration as the vehicle 150 according to the fifth embodiment will not be described.

FIG. 27 is a block diagram of the management device 460. The management device 460 also communicates with the vehicle 160 in the communication unit 463, and the deletion unit 465 instructs the vehicle 160 to delete the authentication key. The same configuration as the management device 450 according to the fifth embodiment is omitted.

FIG. 28 is a flowchart of operations of the management system 21 according to the sixth embodiment. FIG. 28 shows a flow of steps S123 and subsequent operations in the operation of FIG. 24. When mutual authentication cannot be performed in the comparison at step S123 in FIG. 24 (S225: NO), the vehicle 160 displays an authentication error on the display unit 131 (S227), and ends the flow.

When mutual authentication is possible (S225: YES), the vehicle 160 reads a new third authentication key from the battery 250 and stores it (S129). Furthermore, the vehicle 160 transmits an authentication notification indicating that the authentication is mutually successful to the management device 460 (S231).

When the management device 460 receives the authentication notification, it sends a message to the battery 250 A deletion signal for deleting the old first authentication key is transmitted (S233). When the storage battery 250 receives the deletion signal via the station 300, it deletes the old first authentication key (S235).

Similarly, when the management device 460 receives the authentication notification, it sends a deletion signal to the vehicle 160 to delete the old third authentication key (S237). When the vehicle 160 receives the deletion signal, it deletes the old third authentication key (S239). This concludes the process. As described above, the flow of FIG. 28 is repeatedly executed while each device such as the management device 460 is operating.

This embodiment also has the same effects as the fifth embodiment. Furthermore, even if the deletion unit is not provided in the vehicle 160, the old authentication keys of the vehicle 160 and the battery 250 can be deleted.

FIG. 29 is a block diagram of a management device 470 according to the seventh embodiment. The management device 470 is different from the management device 450 in the fifth embodiment in that the management unit 470 does not include the deletion unit 445 and the communication unit 473 communicates with the vehicle 170. The same configuration as the management device 450 according to the fifth embodiment is omitted.

The vehicle 170 is different from the vehicle 150 of the fifth embodiment in a point of communicating with the management device 450 and a point of transmitting a deletion signal to delete the authentication key to the deletion unit 129. The other components are the same as those of the vehicle 150 according to the fifth embodiment, and therefore the block diagram and description are omitted.

FIG. 30 is a flowchart of the operation of the seventh embodiment. FIG. 30 shows a flow of steps S113 and subsequent operations in the operation of FIG. 24. First, in step S315, the management device 470 stores a new second authentication key. However, since the management device 470 does not have a deletion unit, the old authentication key is also left. After that, steps S317 to S335 are the same as steps S117 to S135 of FIG. 24, so the description is omitted.

As a condition that mutual authentication can be performed in step S325, the vehicle 170 sends a request to the management device. 470 sends a delete signal (S337) to delete the old second authentication key recorded in the management device 470 (S339). This concludes the process. As described above, the flow of FIG. 30 is repeatedly executed while each device such as the management device 470 is operating.

This embodiment also has the same effects as the fifth embodiment. Furthermore, after the authentication with the battery 250 in the vehicle 170 is successful, the old authentication key of the management device 470 is deleted. Therefore, if the authentication of the vehicle 170 and the storage battery 250 is unsuccessful due to a certain event despite the regular storage battery 250, the operation can be restarted from step S107 using the old authentication key.

As described above, in the fifth embodiment, the management device and the vehicle have a deletion portion. In the sixth embodiment, only the management device has a deletion portion. In the seventh embodiment, only the vehicle has a deletion portion. Alternatively, only the storage battery may have a deletion portion.

In this case, a comparison unit may be provided in the battery, and the third authentication key may be read from the vehicle and compared with its own first authentication key. In the case where the authentication by the comparison unit is successful, a new third authentication is sent to the vehicle, and the deletion unit of the battery deletes the old second authentication key of the vehicle.

Furthermore, the comparison unit may read the second authentication key from the management device in the storage battery and collate it with the first authentication key of itself. When the authentication of the collation unit is successful, the deletion unit of the battery deletes the old second authentication key of the management device.

In addition, the process of reading and writing the information of the storage battery when the authentication is unsuccessful is the same as the other embodiments.

In addition, each of the management device, the battery, and the vehicle may have a deletion section. In addition, it is not necessary to have a deletion part so that the new authentication key can be triggered by some kind. Programming the way to delete old authentication keys.

In the fifth to seventh embodiments described above, the authentication keys are not particularly limited as long as they can authenticate each other. For example, it is determined that the authentication is successful if at least a part of the authentication keys are the same string, sequence, or combination thereof, and the same part is the same. The authentication key may be determined to be successful if it is a sequence of numbers different from each other, and when a specific operation such as adding the numerical values of each bit is performed to a known solution.

In the fifth to seventh embodiments described above, the management device stores the authentication key for the management device generated every time the battery is returned for the number of batteries lent out until the battery is returned. Alternatively, when the battery is returned, the management device only generates the authentication key for the battery and the vehicle, and maintains a common hash value for all the generated authentication keys. When the battery is returned, the authentication key is not used for mutual authentication. The authentication key for the battery and the vehicle obtained from the battery and the hash value are judged to be genuine batteries and the vehicle.

In the fifth to seventh embodiments described above, each time the battery is returned to the site, the management device newly generates an authentication key that is unique to the management device, the battery, and the vehicle and can be mutually authenticated. The premise is to borrow the same site as the battery site. However, it is also possible to distribute the new authentication key generated by one management device to multiple other management devices, and share the new authentication key among multiple management devices configured at different sites, even if the user returns to and borrows it. The different sites of the battery can also perform mutual authentication of the authentication key between the battery and the management device of the different site. In addition, the management system may additionally include a server that receives newly generated authentication keys from a plurality of management devices and performs one-dimensional management, and returns the user to a site different from the site where the battery is borrowed. At this time, a new authentication key is obtained by querying the server of the management device of the different site, and mutual authentication of the authentication key can be performed between the battery returned by the user and the management device of the different site.

In the fifth to seventh embodiments described above, each time the battery is returned to the site, the management device newly generates an authentication key unique to the management device, the battery, and the vehicle, which can be mutually authenticated. However, it may be replaced by When the battery is returned to the site at a predetermined date and time, for example, after 0 o'clock on January 1 and before 0 o'clock on January 1 of the following year, the management device repeatedly generates a pair of management devices and batteries. And one authentication key common to the vehicle, if it passes 0 o'clock on January 1 of the following year, it will be changed to a new authentication key common to the management device, battery, and vehicle. When the battery is returned, the new one authentication key is repeatedly generated.

In addition, in the fifth to seventh embodiments described above, when the battery is returned, the authentication key of the battery may be updated. In addition, in the above fifth to seventh embodiments, instead of updating the authentication key every time when the battery is lent, the authentication key may be updated at a predetermined timing. As an example of the predetermined timing, the number of times of authentication with the authentication key every fixed period can be mentioned.

In the fifth to seventh embodiments described above, when a new vehicle is introduced, there is no stage for returning the battery, and the battery is loaned out. Therefore, when a battery is installed in a vehicle for the first time, it is preferable that the management company controls the vehicle and causes the vehicle to read a new third authentication key from the battery and store it without performing a collation process. In addition, in a case where the authentication is not successful in step S109 and the like in FIG. 24, the same control can be performed when a new battery is lent.

FIG. 31 is a schematic diagram of a station 1000 as a modification. The station shown in Figure 31 At point 1000, two storage sheds are arranged horizontally as points different from the station 300 shown in FIG.
