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

The authentication key storage unit 124 stores the 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 battery 250 is stored in the battery storage unit 101, the communication unit 102 reads out the first authentication key written in the battery 250 through wired communication or wireless communication, and outputs it to the collation 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 be mutually authenticated, the collation unit 127 outputs authentication information indicating this to the deletion unit 129. When the first authentication key and the third authentication key cannot be mutually authenticated, the collation unit 127 outputs an instruction to display an authentication error message to the display unit 131 and displays the message.

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 when the authentication information is input from the collation unit 127 and store it 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 storage battery 250 via the communication unit 102. In addition, a new first authentication key is written in the storage battery 250, but the deletion unit 129 selectively does not delete the new first authentication key.

FIG. 22 is a block diagram of the storage battery 250. The storage unit 210 of the storage battery 250 includes an authentication key storage unit 218 that stores authentication keys. The authentication key storage unit 218 stores the first authentication key and the third authentication key.

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

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 authentication keys. The authentication key storage unit 430 stores, for example, the second authentication key.

The management device 450 includes a collation unit 441 to collate the authentication key; a generation unit 443 to generate a new authentication key; and a deletion unit 445 to delete the old authentication key stored in the authentication key storage unit 430.

When the comparison unit 441 inputs the first authentication key and the third authentication key from the reading unit 401, it obtains the second authentication key stored in the authentication key storage unit 430, and compares the first authentication key and the third authentication key with the second authentication key, respectively. Authentication key. When the first authentication key, the third authentication key, and the second authentication key can each be mutually authenticated, the collation unit 441 outputs authentication information indicating this to the generation unit 443. When at least one of the first authentication key, the third authentication key, and the second authentication key cannot authenticate each other, the comparison unit 441 will display an authentication error. The instruction of the erroneous message is output to the display unit 307 of the site 300, and the message is displayed. The message can also indicate which authentication key group cannot mutually authenticate.

When the authentication information is input from the collation unit 441, the generating unit 443 generates three new authentication keys that can be mutually authenticated. 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 stored in the authentication key storage unit 430 in advance. The 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 that exists before the authentication key is generated by the generating unit 443 is sometimes referred to as the old authentication key, and the authentication key generated by the generating unit 443 is sometimes referred to as the 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, it will provide information to the user who lent it from the site 300 and returned the battery 250 The instructions written by the battery 250 of 60 are output to the station 300.

For the purpose of clarification only, the management device 450 in this embodiment does not include the presentation unit 405, the management unit 419, the lending processing unit 407, and the place output of the management device 400 according to the first embodiment shown in FIG. Section 412, Excellent Return Award Section 414, and Excellent Envoy The reward unit 416 also does not include the ID list storage unit 429, the related information storage unit 431, the address distance storage unit 433, the area information storage unit 435, and the reward information storage unit 437 included in the storage unit 420 of the management device 400. However, the management device 450 in the present embodiment may be provided with a part or all of these structures included in the management device 400 according to the first embodiment.

FIG. 24 is a flowchart according to the fifth embodiment. The description of the flow of FIG. 24 starts with the specific user 60 returning the storage battery 250 used in the own vehicle 150 to the station 300.

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

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

If any of the first authentication key and the third authentication key cannot be mutually authenticated with the second authentication key (S109: "No"), an authentication error display instruction is output to the site 300 (S111), and the flow is Finish. When any of the first authentication key and the third authentication key can be mutually authenticated with the second authentication key (S109: Yes), the information of the storage battery 250 returned to the site 300 is read (S112). In addition, in the case where mutual authentication is not possible, the site 300 does not read the information of the storage battery 250.

The management device 450 generates a new first authentication key, a new second authentication key, and a new third authentication key (S113), and deletes the old second authentication key stored in the management device 450 Key to store 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 storage battery 250 loaned to the user 60 and outputs the instruction to perform the loan processing to the site 300 (S117 ). In this case, even if other first authentication keys and third authentication keys are stored in the loaned storage battery 250 in advance, they are updated to the above-mentioned first authentication keys and third authentication keys. In addition, the management device 450 preferably lends the battery 250 that has been charged.

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 keeps the old first authentication key with itself Is compared with the old third authentication key (S123).

When the old first authentication key and the old third authentication key cannot be mutually authenticated (S125: No), the vehicle 150 displays an authentication error message (S127), and the flow ends. In the case where the first authentication key and the third authentication key can be mutually authenticated (S125: "Yes"), the vehicle 150 reads out the new third authentication key from the battery 250 and stores it (S129), and deletes its own old The third authentication key (S131). At the same time, the vehicle 150 transmits 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 flow 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 embodiment, in S125, the vehicle 150 may arbitrarily perform the writing process and the reading process of information for the battery 250 on the condition that the authentication key can be mutually authenticated with the lent battery 250.

As described above, according to the management system 19 of this embodiment, even a malicious third party Illegal acquisition of the first authentication key from the storage battery 250 and write it into a low-priced counterfeit product whose quality is not guaranteed. Since the genuine storage battery 250 storing the first authentication key has been returned to the site 300 Update to a new authentication key, so authentication of counterfeit products will not succeed. Therefore, the counterfeit product cannot be applied to any one of the management device 450 and the vehicle 150. Thus, it is possible to prevent the user 60 from unintentionally borrowing a counterfeit product from the power station 300, and it can also prevent the user 60 from borrowing a counterfeit product, which is believed to be a genuine battery 250, from being dissatisfied with, for example, low-horsepower driving and severe battery consumption.

In addition, according to the above-mentioned structure, 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 and reading processing of information to the battery 250. Therefore, it is also possible to prevent information from being written or read. Illegal outflow through imitations.

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

FIG. 26 is a block diagram of the vehicle 160. The vehicle 160 differs in the point where it does not have the deletion unit 129 and the point where the communication unit 162 communicates with the management device 460. In addition, the description of the same structure as that of the vehicle 150 of the fifth embodiment is omitted.

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

FIG. 28 is a flowchart of the operation of the management system 21 of the sixth embodiment. Figure 28 The flow of operations in and after step S123 in the operations in FIG. 24 is shown. In the case where mutual authentication cannot be performed in the comparison of step S123 in FIG. 24 (S225: No), the vehicle 160 displays an authentication error on the display unit 131 (S227), and the flow ends.

When mutual authentication is possible (S225: Yes), the vehicle 160 reads out the new third authentication key from the battery 250 and stores it (S229). Furthermore, the vehicle 160 transmits an authentication notification indicating that the mutual authentication is successful to the management device 460 (S231).

When receiving the authentication notification, the management device 460 transmits a delete signal for deleting the old first authentication key to the storage battery 250 (S233). When the storage battery 250 receives the deletion signal via the site 300, it deletes the old first authentication key (S235).

Similarly, when receiving the authentication notification, the management device 460 transmits a deletion signal for deleting the old third authentication key to the vehicle 160 (S237). When the vehicle 160 receives the deletion signal, it deletes the old third authentication key (S239). Above, the process ends. 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 effect as that of 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 of the fifth embodiment in the point that it does not have the deletion unit 445 and the point that the communication unit 473 communicates with the vehicle 170. In addition, the description of the same configuration as that of the management device 450 of the fifth embodiment is omitted.

The point where the vehicle 170 communicates with the management device 450 and the point where the deletion signal for deleting the authentication key is sent to the deletion unit 129 is different from the vehicle 150 of the fifth embodiment. That Others are the same as the vehicle 150 of the fifth embodiment, so the block diagram and description are omitted.

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

In step S325, mutual authentication is a condition, and the vehicle 170 transmits a delete signal to the management device 470 (S337), and deletes the old second authentication key recorded in the management device 470 (S339). Above, the process ends. 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 effect as that of 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, in the case where the authentication of the vehicle 170 and the storage battery 250 has not succeeded due to a certain event even though it is a regular storage battery 250, it is possible to reuse the old authentication key and start the operation from step S107.

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

In this case, a collation unit may be provided in the battery to read the third authentication key from the vehicle and collate it with its own first authentication key. If the verification by the verification 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 in the storage battery may read the second authentication key from the management device and compare it with its own first authentication key. When the verification by the verification unit is successful, the deletion unit of the storage battery deletes the old second authentication key of the management device.

In addition, if the authentication is unsuccessful, the reading and writing of battery information cannot be performed, which is the same as the other embodiments.

In addition, each of the management device, the storage battery, and the vehicle may have a deletion unit. In addition, it is not necessary to have a deletion unit, so that the new authentication key can be programmed in a way that triggers the deletion of the old authentication key.

In the above fifth to seventh embodiments, the authentication keys are not particularly limited as long as they can be verified by mutual comparison. For example, it is judged that the authentication is successful based on the fact that at least a part of the authentication keys are the same character string, number sequence, or a combination thereof, and the same part is the same. It is also possible to judge that the authentication is successful based on that the authentication key is a different sequence of numbers, and when a specific calculation such as adding the values of each bit is performed, a known solution is exported.

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

In the above fifth to seventh embodiments, when the storage battery is returned to the site, the management device newly generates the management device, the storage battery, and the vehicle's unique, capable The authentication key for mutual authentication is based on the premise that the user returns to the same site as the site where the battery was borrowed. 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 deployed at different sites, even if the user returns to and borrows the new authentication key. Sites with different storage battery sites can also perform mutual authentication of authentication keys between the storage 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 multiple management devices and performs one-dimensional management. When the user returns to a site different from the site where the battery is borrowed, the server will pass through the different site. The management device of the point queries the server to obtain a new authentication key, and can perform mutual authentication of the authentication key between the storage battery returned by the user and the management device of the different site.

In the above fifth to seventh embodiments, when the battery is returned to the site, the management device generates a new authentication key that is unique to each of the management device, the battery, and the vehicle each time. When the battery is returned to the site at a predetermined date and time, for example, after 0:00 on January 1st and before 0:00 on January 1 of the following year, the management device repeatedly generates information for the management device and battery. And one authentication key common to the vehicle. If 0:00 on January 1st of the following year passes, it will be changed to a new authentication key common to the management device, battery, and vehicle. Same as last year, every time to the station When the battery is returned, the new authentication key is repeatedly generated.

In addition, in the above fifth to seventh embodiments, when the storage battery is returned, the authentication key of the storage battery may be updated. In addition, in the above fifth to seventh embodiments, instead of updating the authentication key every time the storage battery is lent, the authentication key may be updated at a predetermined timing. As an example of the predetermined timing, one can cite During a certain period, the number of times the authentication key is used for authentication, etc.

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

FIG. 31 is a schematic diagram of a station 1000 as a modified example. In the station 1000 shown in FIG. 31, as a point different from the station 300 shown in FIG. The storage battery 200 has a transport path between the storage bays, and the storage battery 200 stored in each storage bay can be moved via the transport path.

In addition, in each storage shed, a return port for the battery 200 indicated as IN is arranged at one position, and a discharge port for the loaned battery 200 indicated as OUT is arranged at one position, so that the user 60 cannot visually recognize it from the outside. The storage battery 200 is housed in the storage shed.
