  The configuration of the charging device 1 according to the present embodiment has been described above. Next, the control method and operation executed in the charging device 1 will be described with reference to the flowchart of FIG. In the present embodiment, the control is set so as to be performed corresponding to a plurality of parking spaces having the configuration shown in FIGS.

  First, the control unit 22 determines whether or not a charging start condition is satisfied (step S1). Here, when the charging start condition is satisfied, it is determined whether or not there is a plug moving mechanism for moving the charging plug 11 in the parking space where the vehicle to be charged is arranged (step S2). In Step S2, if there is a plug moving mechanism, that is, a mechanism that includes the guide rail 17 as shown in FIG. 6 and automatically moves the charging plug 11 toward the vehicle-side connector 5B, the charging plug 11 is connected to the vehicle. Automatic connection to the side connector 5B is enabled (step S3). At this time, the lock arm 14A of the charging plug 11 is set to be in an unlocked state regardless of whether or not the vehicle is in the parking space. For this reason, it is possible to prevent the lock arm 14A from interfering with the vehicle-side connector 5B during connection.

  Next, it is determined whether or not there is a vehicle 5 at the parking space position (step S4). In step S4, when the vehicle 5 is arranged in the parking space, it is determined whether or not the vehicle is a reserved vehicle (step S5). This determination is made by connecting the charging plug 11 and the vehicle-side connector 5B to the vehicle ID information obtained by CAN communication from the vehicle 5 side and the reserved vehicle ID input to the reservation management processing unit 21 of the charging facility 2. Based on the information, the reserved vehicle determination unit 24 compares the information.

  After determining in step S5 that the vehicle 5 parked in the parking space is a reserved vehicle, as shown in FIG. 2, the lock arm is operated so that the lock arm 14A is changed from the unlocked state to the locked state. Actuate section 14B. The lock arm operating unit 14B is controlled by the charging plug control means 23, and the connection between the vehicle side connector 5B and the charging plug 11 is locked by the lock arm 14A (step S6).

  After being locked by the lock arm 14A in step S6, power is supplied from the charging stand 16 to start charging (step S7). Thereafter, it is determined whether or not the charging is finished (step S8). In the present embodiment, the information of the battery 5A of the vehicle 5 is set to obtain the information of the battery 5A by CAN communication. However, the battery 5A is detected by a method such as detecting the charging current on the charging device 1 side. Of course, it may be determined whether charging is complete (whether fully charged).

  In step S8, when the charging end condition is not satisfied, the process returns to step S7 and the charging is continued. In step S8, when the charging end condition is satisfied, the charging plug control means 23 performs control to release the locked state of the locking mechanism 14, and then performs control to push out the plug removal pin 15 (step S9). Specifically, in this step S9, the charging plug control means 23 operates the lock arm operating portion 14B, and the lock arm 14A releases the engagement between the charging plug 11 and the vehicle side connector 5B, and then this state is changed. While being held, a drive unit (not shown) is operated to control the plug removal pin 15 so as to protrude from the front end surface of the charging plug 11.

  Next, whether or not there is a mechanism (plug insertion arm 18) for moving the charging plug 11 backward from the vehicle-side connector 5B and a mechanism (guide rail 17 or the like) for moving the charging plug 11 to the home position where the charging stand 16 is disposed. Is determined (step S10). If it is determined in step S10 that these plug separating / moving mechanisms are present, after the charging plug 11 is separated from the vehicle-side connector 5B, the plug insertion arm 18 is rotated to a position where it does not interfere with the vehicle 5. After the movement, the movement to the home position is started along the guide rail 17, and at the same time, the cable winding device 13 is operated to wind the charging cable 12 (step S11).

  In step S11, after the charging plug 11 is moved to the home position, the display device (not shown) provided in the charging stand 16 displays the end of charging, and the reservation management processing unit 21 of the charging facility 2 uses the usage status data. To output charging end information. Accordingly, the reservation management processing unit 21 of the charging facility 2 performs a reservation schedule update process. Further, the reservation management unit 21 outputs a charge end notification to a device designated by the user such as the in-vehicle reservation terminal 5C, the mobile phone 6, and the communication network personal computer 7 via the communication network 3 such as the Internet (step S12). . In this way, the charging plug 11 is automatically inserted and removed as shown in FIG. 6, and the charging process is performed in a facility that has a connection locking function by the lock mechanism 14 and can be moved by the plug insertion arm 18. It can be performed.

  However, if the facility is not as shown in FIG. 6, for example, when the charging plug 11 is manually operated as shown in FIGS. 4 and 5, it is determined in step S2 that there is no plug moving mechanism. In this case, a chargeable notification is made (step S13). Then, it waits until it is confirmed that the charge plug 11 is connected to the vehicle side connector 5B (step S14), and it is determined whether or not the vehicle is a reserved vehicle in step S5.

  In this step S5, when it is determined that the vehicle is not a reserved vehicle, a reservation confirmation is performed (S15), and then the reservation is reset or the charging is performed (step S16). At this time, it is determined whether or not there is a reservation-free charge (step S17). If it is determined in step S17 that there is no reservation, that is, it is determined that there is a reservation, next step S6 is performed.

  When it is determined in step S17 that there is no reservation charging, the charging plug control means 23 connects the vehicle-side connector 5B and the charging plug 11 in an unlocked state, and performs the charging in step 7.

  If it is determined in step S10 that there is no plug separation / movement mechanism, it is confirmed that the charging plug 11 is manually separated from the vehicle-side connector 5B side (step S18), and then a notification in step S12 is made. Do. The information that the charging plug 11 is separated from the vehicle-side connector 5B is input to the charging plug control means 23 via the communication line 12A. Based on this information, the charging plug control means 23 notifies the charging stand 16 and the reservation management processing unit 21 of the end of charging.

  For example, a case where the parking spaces A and B as shown in FIG. 4 are to be used efficiently by using the charging device 1 according to the present embodiment will be described using a reservation schedule as shown in FIG. In the parking spaces A and B shown in FIG. 4, one charging station 16 is arranged. In the parking spaces A and B, one charging plug 11 of the charging stand 16 is selectively used in different time zones.

  As shown in FIG. 8, the reserved time zone of T1 is a time zone in which the vehicle 5 whose vehicle ID is AAAA is reserved in the parking space A of FIG. When the vehicle 5 whose ID is AAAA is fully charged in this reserved time zone T1, the remaining reservation time R1 is reserved, and then the charging device 1 is reserved and parked in the parking space B. It is also possible for the vehicle 5 with the existing vehicle ID BBBB to advance the reservation and use it. Therefore, in this case, it can be avoided that the charging device 1 is not used for the time R1. Further, it is possible to charge the vehicle without reservation (or to make a reservation) for the remaining time R1. In the case of charging the vehicle 5 without a reservation, the charging plug 11 can be moved to the reserved vehicle 5 when the charging is stopped after a predetermined time without locking by the lock mechanism 14. It has become.

  Further, as in the reserved time zone of T2 shown in FIG. 8, it is detected that the vehicle plug 5 having the vehicle ID BBBB waiting in the parking space B is connected to the vehicle-side connector 5B after the reserved time starts. Then, after the reservation vehicle is determined, the lock mechanism 14 is locked and charging is started. The reservation management processing unit 21 updates the reservation status data on the schedule when the battery is fully charged or when the reservation time ends or when the charging is canceled.

  In addition, when the vehicle 5 does not charge even when the reservation time comes, or when the charging ends before the reservation end time, as in the reservation time zone of T3 in FIG. 8, the next parking space A It may be possible to park until the reserved time period, and to avoid leaving the vehicle 5 in combination with setting of a parking fee.

  By performing such schedule management, when the charging of the battery mounted on the vehicle is completed before the end of the charging reservation time, the reservation vehicle is preferentially charged by the lock mechanism 14 until it is fully charged. In addition, it is possible to make it possible to make a reservation for the next reserved vehicle, or to open and charge a vehicle without a reservation for a reserved time. Even if the vehicle 5 of the previous user is left unattended after the end of charging, the charging plug 11 can be moved to the parking space of the vehicle without reservation if the lock mechanism 14 is released. For this reason, the idle time of the charging device 1 can be reduced and the equipment operation rate can be improved. If the charging plug 11 is moved to the home position after the end of charging as in the present embodiment, the end of charging of the previous user can be made clear.

  In the present embodiment, it is necessary to touch the vehicle 5 of the previous user by adopting a configuration in which the charging plug 11 can be automatically inserted, removed and moved as a configuration including the plug insertion arm 18 as shown in FIG. The trouble between users can be reduced. And as shown in FIG. 5, if the vehicle 5 to be charged is parked in advance in the parking space by providing the guide rail 17 and enabling the plug insertion arm 18 to move across a plurality of parking spaces, The vehicle 5 can be charged even when the user is not nearby at the charging start time.

  In the charging device 1 according to the present embodiment, unauthorized use of the charging device 1 and the parking space of the person without reservation can be avoided, and the reservation person can use it with peace of mind within the reservation time.

  Further, in the present embodiment, as shown in FIG. 4, the lock plug 14 is only locked and released at the start and end of charging, and the charging plug 11 is manually replaced after the charging is completed. After that, the configuration automatically moves to the home position, and after charging is completed, the charging plug 11 is automatically removed, and if there is a next reservation, the next reserved vehicle is moved to the parking space where it is parked and automatically connected. If there is no next reservation, a configuration that automatically moves to the home position is included, and the facility operating rate can be improved in the charging device 1 of any configuration. In the present embodiment, it is preferable that at least the release of the lock mechanism 14 is automated by the charging plug control means 23.
