As shown in FIG. 2, the quick charging system 1 performs a communication line establishment process (step S1), an authentication process (step S2), a quick charge process (step S3), and a transaction process (step S4).

  First, communication line establishment processing (step S1 in FIG. 2) will be described based on the block configuration diagram shown in FIG. 1 and the timing chart shown in FIG.

  The wireless communication unit 17 of the quick charger 10 forms a communication area by transmitting a wireless LAN (for example, WiFi) radio wave (step S11). When the mobile communication terminal 20 enters the communication area, a wireless LAN selection screen is displayed on the touch panel 24 (step S12).

  Thereafter, user information and information such as a personal identification number are transmitted from the mobile communication terminal 20 to the quick charger 10 (step S14), and a communication establishment process between them is executed (step S15).

  After communication is established between the quick charger 10 and the mobile communication terminal 20, when a user executes an application for performing quick charging, for example, a screen as shown in FIG. 4B is displayed on the touch panel 24. The intention of using the quick charger 10 is confirmed. In FIG. 4B, a button 24d for executing “use quick charger” and a cancel button 24e for canceling “use quick charger” are displayed. When the user selects the button 24d, a use request signal is transmitted to the quick charger 10 (step S16 in FIG. 3).

  The quick charger 10 that has received the use request signal transmits a signal designating the server device 30 to the server device 30 via the mobile communication terminal 20 (step S17), and between the mobile communication terminal 20 and the server device 30. The communication establishment process is executed (step S18).

  The server device 30 transmits an authentication request signal for authenticating the user and the quick charger 10 to the quick charger 10 via the mobile communication terminal 20 (step S19).

  Next, the authentication process (step S2 in FIG. 2) will be described based on the block configuration diagram shown in FIG. 1 and the timing chart shown in FIG.

  The 1st encryption part 15 of the quick charger 10 acquires various information (step S21). That is, the first encryption unit 15 acquires user information from the user information acquisition unit 11, charger information from the charger information acquisition unit 12, and one-time code from the code generation unit 13.

  Then, the 1st encryption part 15 produces | generates a charge start code from the acquired various information (step S22).

  FIG. 6 shows an example of the charging start code. In FIG. 6, the charging start code 42 includes user information 42a, charger information 42b, and a one-time code 42c. In the illustrated example, the user information 42a is configured by a user ID. The charger information 42b includes information on a charger ID, a charger model, a charger time, and an error code.

  Returning to FIG. 5, the first encryption unit 15 encrypts the charging start code by the first encryption method (step S <b> 23), and outputs it to the wireless communication unit 17.

  On the other hand, similarly to the first encryption unit 15, the second encryption unit 16 obtains user information, charger information, and a one-time code to generate a charge start code, and encrypts the charge start code by the second encryption method. (Step S24) and output to the collation unit 18.

The decryption unit 32 decrypts the encrypted charge start code with the decryption key (step S26), and outputs the decrypted charge start code to the code verification unit 35.

  The code verification unit 35 reads the user information and the charger information from the management information storage unit 33, compares the user information and the charger information included in the charging start code (step S27), and succeeds in the authentication of the user and the charger. It is determined whether or not it has been done (step S28). Here, if the user information and charger information read from the management information storage unit 33 matches the user information and charger information included in the charging start code, the code verification unit 35 authenticates the user and the charger. In other cases, it is determined that the user and the charger are not successfully authenticated. Further, the code verification unit 35 determines that the authentication is not successful even when a predetermined error occurs in the quick charger 10.

  In step S28, when the code verification unit 35 determines that the user and the charger are successfully authenticated, the charger information update unit 36 refers to the charger information included in the charging start code and stores the charger information. The accumulated information in the unit 34 is updated (step S29). Then, the encryption unit 37 encrypts the charging start code as a use permission code by the second encryption method (step S30), and outputs it to the wireless communication unit 31.

  The wireless communication unit 31 transmits the encrypted use permission code to the quick charger 10 via the mobile communication terminal 20 (step S31).

  On the other hand, if the code verification unit 35 does not determine in step S28 that the authentication of the user and the charger has succeeded, the encryption unit 37 encrypts error information indicating that the user information or the charger information is invalid. The data is output to the wireless communication unit 31 without being converted. The wireless communication unit 31 transmits this error information to the quick charger 10 as in step S31 described above.

  In the quick charger 10, the collation unit 18 collates the encrypted use permission code received by the wireless communication unit 17 and the charge start code encrypted by the second encryption unit 16 in step S24 (step S24). S32). Here, when the server device 30 successfully authenticates the user and the charger, the usage permission code and the charging start code match, and the charging control device 19 authenticates to the mobile communication terminal 20 via the wireless communication unit 17. Is transmitted (step S33), and the process proceeds to the quick charge process (step S3 in FIG. 2). On the other hand, if the server device 30 does not succeed in authenticating the user and the charger, the use permission code and the charging start code do not match, and the authentication process is terminated (step S34), and the charging service is not provided. .

  Next, the quick charge process (step S3 in FIG. 2) will be described based on the block configuration diagram shown in FIG. 1 and the timing chart shown in FIG. It is assumed that the power feeding connector of the quick charger 10 is connected to the power receiving connector of the electric vehicle.

  In the quick charger 10, the user and the charger are successfully authenticated in the above-described step S32 (see FIG. 5), and the charging control device 19 displays a charging start screen on the display panel (step S41).

  On the other hand, the mobile communication terminal 20 receives the authentication success signal in the above-described step S33 (see FIG. 5). Based on the authentication success signal, the charging start screen is displayed on the touch panel 24 by the application stored in the program memory 23 (step S42). That is, the user can operate one of the charging start screens displayed on the quick charger 10 and the mobile communication terminal 20.

  An example of the charge start screen displayed on the touch panel 24 is shown in FIG. 4C, the touch panel 24 displays a charge start button 24f and a cancel button 24g for canceling the charge start. When the user selects the charge start button 24f, the first wireless communication unit 21 transmits a charge start request signal to the quick charger 10 under the control of the control unit 25 (step S43).

  When the wireless communication unit 17 of the quick charger 10 receives the charge start request signal or when the user operates the charge start button on the charge start screen displayed on the display panel of the quick charger 10, the charge control device 19 It communicates with the charging device on the vehicle side, and confirms whether the electric vehicle and the quick charger 10 are in a state in which quick charging can be normally executed (step S44). For example, the charging control device 19 performs an insulation test on the electric vehicle and the quick charger 10. If the normal state cannot be confirmed in step S44, the process ends without performing the quick charge process.

  When it is confirmed in step S44 that the state is normal, the charging control device 19 starts providing the charging service. That is, the charging control device 19 locks the power feeding connector to the power receiving connector (step S45), so that the user cannot remove the power feeding connector from the power receiving connector. And the charging control apparatus 19 outputs an electric current with respect to an electric vehicle (step S46).

  The charging control device 19 transmits charging information during rapid charging to the mobile communication terminal 20 via the wireless communication unit 17 at predetermined time intervals (step S47). The touch panel 24 of the mobile communication terminal 20 displays the received charging information (step S48).

  An example of the charging information displayed on the touch panel 24 is shown in FIG. As shown in FIG. 4D, the touch panel 24 displays charging time information 24h, charging power amount information 24i, and a charge 24j as charging information. These displays are updated every predetermined time. In addition, a charging interruption button 24k for interrupting charging is displayed on the touch panel 24, and the user can interrupt rapid charging by selecting the charging interruption button 24k.

  Returning to FIG. 7, the control unit 25 determines whether or not the charge interruption button 24k has been selected (step S49). Here, when it is not determined that the charging interruption button 24k is selected, the process returns to step S48, and the touch panel 24 displays the charging information.

  If it is determined in step S49 that the charging interruption button 24k has been selected, the control unit 25 transmits a charging interruption signal for interrupting charging to the quick charger 10 via the first wireless communication unit 21 ( Step S50).

  On the other hand, the charging information illustrated in FIG. 4D is also displayed on the display panel of the quick charger 10 (step S51). Then, the charging control device 19 determines whether or not the user has selected the charging interruption button displayed on the display panel (step S52). If it is determined that the charging interruption button has been selected, the process proceeds to step S54. If it is not determined that the charging interruption button has been selected, the process proceeds to step S53.

  In step S53, the charging control device 19 determines whether or not the charging is completed. If it is determined that the charging is completed, the process proceeds to step S54 and stops outputting the current (step S54). On the other hand, if the charging control device 19 does not determine that the charging has ended, the charging control device 19 returns to step S46.

  Then, the charging control device 19 displays a charging end message indicating that charging has ended on the display panel (step S55), and sends a charging end signal indicating that charging has ended via the wireless communication unit 17 to the mobile communication terminal. 20 (step S56). After the mobile communication terminal 20 receives the charging end signal, the touch panel 24 displays a charging end message (step S57).

  Next, transaction processing (step S4 in FIG. 2) will be described based on the block configuration diagram shown in FIG. 1 and the timing chart shown in FIG.

  The 1st encryption part 15 of the quick charger 10 acquires various information after charge (step S61). That is, the first encryption unit 15 acquires charger information from the charger information acquisition unit 12 and charging result information from the charging information acquisition unit 14.

  Then, the 1st encryption part 15 produces | generates a charge completion code from the acquired various information (step S62).

  FIG. 9 shows an example of the charge completion code. In FIG. 9, the charging completion code 43 includes charger information 43a and charging result information 43b. The charger information 43a includes a charger ID and an error code. The charge result information 43b includes information such as a charge time, a charge power amount, a charge start time, a charge end time, a charge remaining battery level, and a charge end battery level.

  Returning to FIG. 8, the first encryption unit 15 encrypts the charging completion code by the first encryption method (step S <b> 63), and outputs it to the wireless communication unit 17.

  On the other hand, like the first encryption unit 15, the second encryption unit 16 obtains charger information and charge result information, generates a charge completion code, and encrypts the charge completion code using the second encryption method (step S64) and output to the collation unit 18.

  The wireless communication unit 17 transmits the encrypted charge completion code to the server device 30 via the mobile communication terminal 20 (step S65).

  The wireless communication unit 31 of the server device 30 receives the encrypted charge completion code and outputs it to the decryption unit 32. The decryption unit 32 decrypts the encrypted charge completion code with the decryption key (step S66), and outputs it to the code verification unit 35.

  The code verification unit 35 reads the charger information from the management information storage unit 33, compares it with the charger information included in the charge completion code (step S67), and determines whether or not the authentication of the charger is successful (step S67). S68). Here, when the charger information read from the management information storage unit 33 matches the charger information included in the charging completion code, the code verification unit 35 determines that the authentication of the charger is successful, Otherwise, it is determined that the charger has not been successfully authenticated.

  If it is determined in step S68 that the code verification unit 35 has succeeded in authenticating the charger, the billing settlement unit 38 communicates with the billing settlement server 41 via the wireless communication unit 31 and the network 5 to perform billing settlement processing. This is performed (step S69).

  The charger information update unit 36 updates the charger management information in the charger information storage unit 34 with reference to the charger information and the charging result information included in the charging completion code (step S70). Then, the encryption unit 37 encrypts the charging completion code as a transaction completion code by the second encryption method (step S71), and outputs it to the wireless communication unit 31.

  The wireless communication unit 31 transmits the encrypted transaction completion code to the quick charger 10 via the mobile communication terminal 20 (step S72).

  On the other hand, if the code verification unit 35 does not determine that the charger authentication has succeeded in step S68, the encryption unit 37 performs wireless communication without encrypting error information indicating that the charger information is invalid. To the unit 31. The wireless communication unit 31 transmits this error information to the quick charger 10 as in step S72 described above.

  In the quick charger 10, the collation unit 18 collates the encrypted transaction completion code received by the wireless communication unit 17 with the charge completion code encrypted by the second encryption unit 16 in step S64 (step S64). S73). Here, when the authentication of the charger is successful in the server device 30, the transaction completion code and the charging completion code match, and the charging control device 19 releases the lock of the power feeding connector (step S74). The charging service is terminated.

  The charging control device 19 displays a transaction completion message indicating that the transaction is completed on the display panel (step S75), and transmits a transaction completion signal indicating that the transaction is completed to the mobile communication terminal 20 via the wireless communication unit 17. Transmit (step S76). After the mobile communication terminal 20 receives the transaction completion signal, the touch panel 24 displays a transaction completion message (step S77).

  On the other hand, when the authentication of the charger is not successful in the server device 30, the transaction completion code and the charging completion code do not match, and the charging control device 19 causes the service person to investigate the cause of the authentication failure. A message to that effect is displayed on the display panel (step S78).

  As described above, the quick charging system 1 according to the present embodiment is configured to perform the authentication process of the user who uses the quick charger 10 and the authentication process of the quick charger 10 via the mobile communication terminal 20. Even when the device 10 is not connected to the network, the authentication process can be performed.
