Since the charging trays 1A to 1D have the same configuration, the charging tray 1A will be described here as a representative. The charging tray 1A has a rectangular plate-like structure in a plan view, and on the lower surface side thereof, a tray-side current collector 13A that can be electrically contacted with the power supply terminal 12A and an electric power supply terminal 12B can be electrically contacted. A tray-side collector 13B is provided. These tray-side collecting electrons 13A and 13B are arranged at diagonal positions on the left and right of the charging tray 1A in the approach direction of the electric vehicle, respectively. In this way, the tray-side collectors 13A and 13B are arranged diagonally to the left and right of the approach direction of the electric vehicle in the charging tray 1A, and are located in the charging space 8A and the charging space 8B as described above. By arranging the power supply terminals 12A and 12B at diagonal positions, the charging tray 1A can be stored in the charging space 8A in the moving direction of the arrow A, and into the charging space 8B in the moving direction of the arrow B. Can be stored. Further, the mechanical parking device is provided with a swivel device by arranging the tray-side collectors 13A and 13B at diagonal positions on the left and right of the approach direction of the electric vehicle in the charging tray 1A. Even when the charging tray 1A is swiveled by the swivel device, the tray-side collectors 13A and 13B can face the feeding terminals 12A and 12B without depending on the orientation of the charging tray 1A.

Further, in the corners on the upper surface side of the charging trays 1A to 1D, foldable charging stands 15A and 15B having charging outlets 14A and 14B electrically connected to the battery of the electric vehicle are provided. ..

In the first embodiment, when charging is performed while the electric vehicle is parked by operating the operation panel, the control device selects, for example, the charging tray 1A, sets a charging reservation, and stores the charging. At the same time, the charging tray 1A is prepared on the elevating table 6 of the elevating chamber 2. On the other hand, when parking of a general vehicle is selected by operating the operation panel, for example, a general tray 10A is prepared on the elevating table 6 of the elevating chamber 2.

When the charging tray 1A is prepared on the elevating table 6 of the elevating chamber 2, the door 3 of the entrance / exit of the elevating chamber 2 is opened. Here, the driver of the electric vehicle rides the electric vehicle on the charging tray 1A of the elevating table 6. After that, when it is detected by a photoelectric detection device (not shown) that the driver leaves the electric vehicle and goes out from the door 3 and the operation switch of the elevating device is operated, the door 3 is closed.
Next, the control device gives a signal to the lift drive unit and the tray drive unit to convey the charging tray 1A to the storage space of the storage area for storing general vehicles other than the charging space 8A or 8B. From this time onward, the elevating device 4 can be prepared for the next warehousing / delivery. Here, the charging tray 1A in which the electric vehicle is mounted is not directly carried into the charging space, but is temporarily moved to the storage space. If the warehousing is carried out at any time according to this method, it is possible to warehousing the electric vehicle reserved for charging by using the charging trays having more than the number of charging spaces 8A and 8B. Moreover, since the electric vehicle for which the charging reservation is set is made to stand by in the storage area, it is not necessary to restrict the warehousing with the lift device 4, and the warehousing / delivery processing can be efficiently performed.

After this, the control device determines whether the electric vehicle in the charging space 8A or 8B is in a fully charged state, or whether the charging spaces 8A and 8B are free. When the electric vehicle in the charging space is fully charged, the charged charging tray is moved to another storage space to form a space in the charging space. On the other hand, if there is no space in the charging space because another electric vehicle is charging, wait for the charging space to complete charging earliest.

Here, when a vacancy is formed in the charging space 8A, the control device stores the charging tray 1A for which the charging reservation is set while controlling the floor side driving device and the tray side driving rail frame. The storage space 9A is moved to 9A, and the storage space 9A is stored in the vacant charging space 8A in the moving direction indicated by the arrow A. On the other hand, when a vacancy is formed in the charging space 8B, the charging tray 1A is moved to the storage space 9F and stored in the vacant charging space 8B from the storage space 9F in the moving direction indicated by the arrow B.

When the charging tray 1A is stored in the charging space 8A, the tray-side current collector 13A is in electrical contact with the power feeding terminal 12A to form a charging circuit, and charging is started. On the other hand, when the charging tray 1A is stored in the charging space 8B, the tray-side current collector 13B is in electrical contact with the power feeding terminal 12B to form a charging circuit, and charging is started.

The charging tray with the fully charged electric vehicle mounted can be stored in various ways. For example, the charging tray can be stored in the charging space as it is and moved to the storage space as needed, the charging tray can be moved from the charging space to the storage space at any time, and the charging tray is always stored in the charging area. A number can be set, and when the number exceeds this set number, the charging tray can be quickly controlled to move to the storage area.

Since the charging tray 1A on which the fully charged electric vehicle is mounted is moved to a storage space other than the charging space 8A or 8B, the number of electric vehicles to be parked increases. Even if the number of charging trays increases, it is possible to perform an efficient charging service by moving the charging trays on which the charged electric vehicle is mounted to the charging space 8A or 8B.
