  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 authenticates the current user and the charger. It is determined whether or not it has succeeded (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 matches the current user and the charger. It is determined that the authentication has succeeded. Otherwise, it is determined that the current user and the charger have not been 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 authentication of the current user and the charger has succeeded, the charger information update unit 36 refers to the charger information included in the charging start code, and the charger information The storage information in the storage 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 first mobile communication terminal 20 (step S31).

  On the other hand, if the code verification unit 35 does not determine in step S28 that the current user and the charger are successfully authenticated, the encryption unit 37 displays 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 encrypted. The wireless communication unit 31 transmits this error information to the quick charger 10 as in step S31 described above.

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 current user can operate one of the charging start screens displayed on the quick charger 10 and the first 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 current 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 current 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 electric vehicle side and confirms whether the electric vehicle and the quick charger 10 are in a state in which the 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. In other words, the charging control device 19 locks the power feeding connector to the power receiving connector (step S45) so that the current 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 first mobile communication terminal 20 via the wireless communication unit 17 at predetermined time intervals (step S47). The touch panel 24 of the first mobile communication terminal 20 displays the received charging information (step S48).

These displays are updated every predetermined time. The touch panel 24 displays a charging interruption button 24k for interrupting charging, and the current user can interrupt the 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 current 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 first time. It transmits to the portable communication terminal 20 (step S56). After the first mobile communication terminal 20 receives the charging end signal, the touch panel 24 displays a charging end message (step S57).
