  Next, Tables 1 to 3 show examples of the device table and management table stored in the management DB 141, which is the DB of the management server 14, and the authentication / billing table stored in the authentication / billing DB 142. Data for authentication (authentication information) is stored in an authentication information storage unit in the authentication / billing DB 142, and data for charging (billing information) is stored in a charging information storage unit in the authentication / billing DB 142.

  Table 1 is a table showing an example of the device table. The device table is a table for registering information on available devices, a device ID that uniquely identifies the device, a device type (whether it is ESSC or EVSE), a device manufacturer, a model number, The serial number and device name are included. Device IDs are assigned in the order registered in the device table. With this table, for each device including ESSC and EVSE, the manufacturer, model number, serial number, and device name of the device can be known, and the processing contents of the vendor dependent unit 112 based on these data Can be changed depending on the vendor, and the user or the like can also check the performance and standards of each device.

  The manufacturer name and model number of the EVSE 12 device are used when the ESSC 11 recognizes the EVSE 12, and are written as, for example, a property file in the memory 110 of FIG. 1A on the ESSC 11 side. Further, it is written in the management DB 141 of the management server 14 (Table 1). The manufacturer name and model number of the ESSC 11 device are also used when the management server 14 recognizes the ESSC 11, and thus are written in the management DB 141 of the management server 14 (Table 1). Thereby, in the process of FIG. 3A-FIG. 3D mentioned later, recognition of EVSE12 by ESSC11 and recognition of ESSC11 by the management server 14 are attained.

  The serial number and device name are data for the server administrator to identify EVSE and ESSC.

  Table 2 stores the ID of a charging spot (such as a stand that can be charged) and the IDs of ESSC and EVSE provided at the charging spot. In the charging spot I, EVSE0002, 0003,... Are registered for ESSC0001, and EVSE0005, 0006,. That is, this table shows the relationship between the ESSC provided for each charging spot and the EVSE managed by the ESSC.

  When registering the charging spot, ESSC, EVSE in the database, 1. 1. Charging spot ESSC, 3. Register in order of EVSE. The reason is that, in order to register EVSE, ESSC and charging spot information are required. When information is deleted from the device table, the information is deleted in the reverse order of registration. In the device table, ESSC and EVSE are mixed, but device IDs are assigned in the order registered in the DB.

  Table 3 is a diagram showing a configuration example of the authentication / billing table stored in the authentication / billing DB 142 (including the authentication storage unit). The authentication / billing table relates to the user ID, the card ID in the name of the user, the authentication password (PW), the date and time of charging, the ID of the EVSE that performed charging, and the EVSE status for each card ID. Management information including status information (charger usage status information indicating charger usage status such as preparation, standby, charged, charging, etc.), and charging information including whether or not charging has been performed, a charging amount, etc. And are stored. The management information may be stored in the management table of Table 2 so that the management information is associated with the card ID or the like. Information for authentication (a user ID, a card ID in the name of the user, an authentication password (PW), etc.) is referred to as authentication information. When the authentication is performed using a card ID (authentication ID), the authentication information reading unit (card reader) 114 of the ESSC 11 is put in the card to read the authentication ID, and this authentication ID matches the card ID shown in Table 3. If so, the user authentication may be permitted, or the user authentication is performed depending on whether or not the PW input by the user from the GUI (operation) unit 117 matches the authentication PW of the management server. May be.

  Table 1 and Table 2 are associated with each other by device ID, and Table 2 and Table 3 are also associated with each other by device ID. That is, by the device ID of EVSE, device attribute information such as device type, manufacturer and model number, information related to the installation location of the device such as a charging spot and ESSC, the date and time when the charging process was actually performed, the amount of charge, etc. Information relating to charging management and information relating to charging are associated with each other.

  An example of processing for managing the EVSE 12 in the charging system S configured as described above will be described with reference to FIGS. 2A to 2C and FIGS. 3A to 3D. In addition, the following description is an example and it is not limitedly interpreted regarding places, such as a shopping center and a parking lot, the main body of a process, etc. The following processing is executed by instructing each function unit with the operation unit 118 of the ESSC 11, the control unit 12a of the EVSE 12, and the control unit 140 of the management server as control entities.

  First, a user parks EV13 near a parking lot of a commercial facility such as a shopping center (charging spot in the management table in Table 2), for example, EVSE12 (for example, EVSE0002 in Table 2) installed at charging spot I. Then, for example, by touching the welcome screen (S201, S301) on the display unit 12f of the EVSE12 (S202, S302), the connector connection screen is displayed on the touch screen of the EVSE12 (S203, S303), and the connector ( When the connection part 12i) and the connected part 13a of the EV 13 are connected by, for example, the sensor part 12g (for example, connection / disconnection is detected by a pressure sensor or the like) (S204, S304). ), The connection that reports the connection confirmation on the screen of the display section 12f of the EVSE 12. Confirmation screen is displayed, the connection confirmation processing with the EVSE12 and EV13 is made (S205, S305).

  In the present embodiment, when the EVSE 12 locks the connector and transmits connection confirmation start information from the communication unit 12h to the ESSC 11 via the charger communication unit 113, the ESSC 11 enters a charging ready state. (The state of the EVSE 12 is updated. That is, the EVSE state information in the management information of the authentication / billing table is updated from the charging instruction waiting state to the charging preparation state). When the connection confirmation of the connector (the connected part 13a and the connection part 12i) in the EV 13 is started in the EVSE 12, a connection confirmation process between the EVSE 12 and the EV 13 is performed (S205, S305).

  In the connection confirmation process (S205, S305), if the connection is OK (OK), a connection confirmation completion screen is displayed on the display unit 12f of the EVSE 12 (S206, S306), and the user is installed in the store. (S207, S307). If the specification is such that charging is started with a connector lock, if the connector lock is released within a certain period of time, the connection confirmation start information is displayed in ESSC 11 (ESSC0001 in Table 2 associated with EVSE0002). Transmitted from the communication unit 12h via the charger communication unit 113, and the ESSC enters a charging standby state (updates the EVSE usage state. That is, the EVSE of the management information of the authentication / billing table via the network NT) The state information is updated from the charge preparation state to the charge standby state.) That is, in accordance with the lock / release processing of the connector lock, the ESSC 11 performs control to update the charger usage state information such as EVSE 12 charging preparation, charging standby, and charging start. As a result, the charge state of EVSE is updated. In addition, on the display unit of the GUI unit 117, various screen displays according to the usage state information (the above-mentioned welcome screen, charger selection screen, user authentication start screen, user authentication completion screen, charge start screen, charging Notification to the user such as a middle screen, a charging stop instruction screen, a charging completion screen, and a maintenance screen, or a display prompting the user to perform an operation) is performed. The connector lock releasing process is a process arbitrarily performed according to the specification.

  On the other hand, if the connection confirmation between the EVSE 12 and the EV 13 fails, the charging is stopped (charging errors: S210 and S310).

  When the user who has moved to ESSC 11 (0001 in Table 2) touches, for example, the welcome screen (S208, S308) of ESSC 11, for example (S209, S309), ESSC 11 notifies ESSC information to management server 14 ( S310-1), the management server 14 refers to the management DB 141, acquires information on the ESVE 12 controlled by itself (ESSC) based on Table 2 (S310-2), and selects the charger based on this information A device selection screen is displayed (S211, S311). The user can select the charger EVSE (0002) connected to the EV 13 to be charged from the charger selection screen (S212, S312).

  Instead of this selection process, the IC card is read by a card reader (not shown) of the EVSE 12, and the authentication ID stored in the IC card is stored in the authentication ID storage unit of the memory 12e. The charger EVSE (0002) may be selected by confirming that it matches the authentication ID read by the authentication information reading unit 114 of the ESSC 11.

  When the charger EVSE (0002) connected to the EV 13 is selected on the charger selection screen of the ESSC 11, a user authentication start screen is displayed (S213, S313), and user authentication processing is performed (S214, S314). ). This user authentication process is performed, for example, when the user holds the authentication card over the authentication information reading unit 114 provided in the ESSC 11, and for example, a combination of the user ID and the card ID in the authentication / billing table of Table 3 The authentication process is completed by inputting the predetermined PW. That is, when the ESSC 11 obtains an authentication ID via a card reader, displays an authentication message screen on the GUI (operation) unit 117, and transmits the authentication ID to the management server 14, for example, the authentication / billing server by PW input or the like. The authentication of the user is performed in cooperation with, and the authentication result is returned from the management server 14 to the ESSC 11. Here, if the authentication result is NG, a charging error occurs. Basically, if user authentication fails in (S214, S314), re-authentication is performed (S220). However, even if re-authentication is performed, charging is stopped if authentication is NG (S221).

  If the authentication result is OK, a user authentication completion screen is displayed on the screen of the GUI (operation) unit 117 of the ESSC 11 (S215, S315), and an instruction to start charging is issued from the ESSC 11 to the EVSE 12, in response to this. EVSE 12 locks the connector. Then, the connection confirmation start information is transmitted from the EVSE 12 to the ESSC 11, the state of the EVSE 12 is updated to the charge preparation state, the connection confirmation start information is transmitted to the management server, and the EVSE state of the management information in Table 3 is charged. Update to ready state.

  Among the management information of Table 3, in the charging preparation state in which the charger usage state information is being prepared, the connection confirmation between the EVSE 12 and the EV 13 is performed again (S216, S316), the connection confirmation is completed, and the above ( If the connector lock is not released within a certain time as in the case of S205, S305), a charging start command is transmitted from the ESSC 11 to the EVSE 12, and the EVSE 12 starts charging to the EV 13 (S217, S317). In addition, if the connection confirmation fails in (S216, loop of S314 in FIG. 3B), charging is stopped (S221, charging error in FIG. 3B). When connection confirmation start information is transmitted from the EVSE 12 to the ESSC 11, the state of the EVSE is updated by the ESSC 11, and when information indicating that charging is being performed as connection confirmation start information is transmitted to the management server 14, the management is performed. EVSE status information in the server 14 is updated during charging.

  When the charger usage state information is being charged (charging), the ESSC 11 requests the EVSE 12 to check the charging status, and the charging screen is displayed for both the ESSC 11 and the EVSE 12 according to the charging status (S218, S318). . When the charging is completed, a charging end signal is transmitted from the EV 13 (S219, S319), and the charging completion screen is displayed for both the ESSC 11 and the EVSE 12 (S222, S320). For example, when the user touches the screen of the EVSE 12, An instruction to disconnect the connector from the EV 13 is displayed on the screen. For example, when the user or administrator disconnects the connector from the EV 13 (S223, S321), a usage end screen is displayed on the EVSE 12 screen (S224, S322). At this time, the connector disconnection information is transmitted from the EVSE 12 to the ESSC 11, the EVSE state is updated to standby, the connector disconnection information is transmitted to the management server 14, and the management information of the authentication / billing table of the management server 14 is updated. Update. With the update of the state of the EVSE 12 in the management server 14, the management information in Table 3 is updated. For example, the user can know the current state of the EVSE 12 from the display screen of the ESCC 11 based on this information.

  The notification that charging is completed may be configured to be notified from the ESCC 11 to a portable terminal carried by the user by e-mail or the like.

  Here, based on the card ID in Table 3 and the management information (in particular, the charging time or charge amount measured by the timer 12b or the like), charge amount information (3000 yen is created for the card 001 in Table 3), If the billing process is complete, the information “done” is stored, and if the billing process is not complete, the information “not yet” is stored. Or may be deducted from billing.

  As described above, according to the charging system according to the present embodiment, in a facility that wants to attract customers, such as a commercial facility, an increase in customers who want to use a charger is expected, and an increase in sales is also expected. In addition, the charger user can enjoy shopping and meals at commercial facilities during charging, and can effectively use the charging waiting time.

  In the above-described embodiment, the configuration and the like illustrated in the accompanying drawings are not limited to these, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention.
