This acceptance completion screen is displayed when the timely charging button 71 is pressed in FIG. 5, when the decision button 75 is pressed in FIG. 6, or when the reserved charging button 70 or the timely charging button 71 is pressed in FIG. indicate. The operation panel 28 receives notification of the scheduled time for starting charging from the control device 30 and displays the scheduled time. Thereby, not only when the charge start time is specified, but also when the charge start time is not specified, the guide of the charge start time is notified. In addition, when the notification of the scheduled time required for charging is received from the control device 30, not only the scheduled time but also the scheduled time may be displayed.

  FIG. 9 is a block diagram illustrating the function and configuration of the control device 30. Each block shown here can be realized by hardware such as a computer (CPU) (Central Processing Unit) and other elements and mechanical devices, and software can be realized by a computer program or the like. The functional block realized by those cooperation is drawn. Therefore, it is understood by those skilled in the art who have touched this specification that these functional blocks can be realized in various forms by a combination of hardware and software.

  The control device 30 includes a reception unit 112, a determination unit 114, a management unit 116, a detection unit 118, and a holding unit 120. The holding unit 120 includes a vehicle information holding unit 122 and a reservation information holding unit 124.

  The vehicle information holding unit 122 holds the vehicle management number and the type of vehicle specified by the vehicle management number in association with each other. Information indicating whether the vehicle is an EV vehicle is stored as the type of vehicle. In the case of an EV vehicle, the time required for quick charging and the time required for normal charging are held as the position information of the power supply port and the scheduled time required for charging. For example, 30 minutes is held as the time required for quick charging, and 5 hours is held as the time required for normal charging. In addition, it is desirable to set an appropriate value for the required charging time depending on the model of the EV vehicle, the battery capacity mounted on the EV vehicle, and the like.

  FIG. 10 is a diagram illustrating an example of schedule information held in the reservation information holding unit 124. The reservation information holding unit 124 holds schedule information related to charging reservations for EV cars loaded for each charging pallet. The reservation information holding unit 124 holds, as schedule information, a pallet number, a vehicle management number, a reservation pattern, a charging method, a scheduled time, a scheduled time, a warehousing time, and a charging state.

  This figure shows a state in which seven charging pallets are registered, and schedule information regarding EV cars for which charging is reserved is registered in six of them. The pallet number is an identification number for identifying each pallet. In this embodiment, in order to identify a plurality of charging pallets, numbers “1” to “7” are assigned to the respective charging pallets. The reservation pattern identifies whether or not the start time is designated as a charge reservation method, and “reserved charge” or “timely charge” is set. As the charging method, normal charging or rapid charging is set. The state of charge is a status indicating whether or not the vehicle has been charged, and is set to “waiting for charging”, “charging”, “interruption of charging”, and “charged”.

  Returning to FIG. 9, the receiving unit 112 receives a control signal transmitted from the operation panel 28 and transmits a control signal including information to be displayed on the touch panel 60 to the operation panel 28. When the reception unit 112 receives a warehousing request signal, a warehousing instruction signal, and a warehousing instruction signal from the operation panel 28, the reception unit 112 notifies the management unit 116 of the contents. When the reception unit 112 receives a reception signal related to the charge reservation from the operation panel 28, the reception unit 112 notifies the determination unit 114 of the content. When receiving the notification of the scheduled time from the determining unit 114, the receiving unit 112 transmits a control signal including the scheduled time to the operation panel 28.

  The determination unit 114 determines the scheduled time required for charging based on the control signal received by the reception unit 112, and confirms the vacant schedule of the charging space that can secure the scheduled time with reference to the reservation information holding unit 124 Then, the scheduled charging start time corresponding to the empty schedule is determined.

  When receiving the charging method acceptance signal, the determining unit 114 determines the scheduled time required for charging with the charging method selected with reference to the vehicle information holding unit 122. For example, when an acceptance signal indicating that quick charging is selected is received, the scheduled time for charging is 30 minutes, and when an acceptance signal indicating that normal charging is selected is received, the estimated time is 5 hours. To do. The determination unit 114 confirms an empty schedule of the charging space using the determined scheduled time.

  FIG. 11 is a diagram schematically showing the vacant schedule of the charging space, and is a schedule table in which the schedule information shown in FIG. 10 is arranged in time series. In this figure, the vacant schedule when two charging spaces A and B are provided is shown, the schedule information of the reserved charge pattern is outlined, and the schedule information of the timely charge pattern is shaded. When the determination unit 114 receives the reservation charge acceptance signal, the determination unit 114 refers to the reservation information holding unit 124 and confirms whether or not an empty charging space can be secured at the specified charge start time. The determination unit 114 counts the number of schedule information that is registered redundantly in the time period from the charging start time until the scheduled time elapses, and when the count number is less than the number of charging spaces, the charging space It is determined that a free space can be secured.

  For example, when 22:00 is specified as the charging start time and 30 minutes is required as the scheduled time required for quick charging, the determination unit 114 is registered overlapping with the “designation 1” time zone of FIG. 11. Count the number of schedule information. In this case, since the overlapping schedule information is only the schedule information with the pallet number “1”, the count number is 1, which is less than the number of charging spaces. Therefore, it is determined that the charging space can be secured during the “designation 1” time zone.

  On the other hand, when 23:00 is specified as the charging start time and 30 minutes is required as the scheduled time required for quick charging, the determination unit 114 is registered overlapping with the “designation 2” time zone of FIG. 11. Count the number of schedule information. In this case, since there are schedule information with a pallet number “1” and schedule information with a pallet number “3” as overlapping schedule information, the count number is 2, which is not less than the number of charging spaces. Therefore, it is determined that the charging space cannot be secured during the “designation 2” time zone.

  When the charging space held in the reservation information holding unit 124 can be secured, the determining unit 114 determines the charging start time as the scheduled time and notifies the receiving unit 112 of the charging start time. On the other hand, if the charging space cannot be secured, an alternative time at which the charging space can be secured is searched, and the searched alternative time is notified to the reception unit 112.

  When a plurality of candidates are found as alternative times, the determination unit 114 gives priority to a time close to the designated charging start time. For example, if a vacant space could not be secured in the “designated 2” time zone of FIG. 11, the scheduled time of 30 minutes can be secured, and the “alternate” time zone as the closest start time at 23:00 of the scheduled time 22:30 as the start time corresponding to is notified as an alternative time.

  In addition, when receiving the timely charge acceptance signal, the determination unit 114 refers to the reservation information holding unit 124 and searches for a start time at which a charging space can be secured. The determination unit 114 determines the searched start time as the scheduled charging start time, and notifies the reception unit 112 of it. Note that the determination unit 114 determines, as the scheduled time, the earliest possible time when the charging space is available.

  For example, if there is a charge reservation with a timely charging pattern at 21:40 and 30 minutes is required as a scheduled time for rapid charging, the time zone in which the vacant space shown in FIG. It is 30 minutes from 22:00. Therefore, the determination unit 114 determines the scheduled start time for charging as 22:00. If there is a similar charge reservation at 23:00, the determination unit 114 sets the scheduled start time for charging to 1:30.

  When determining the scheduled time, the determination unit 114 registers the schedule information corresponding to the determined content in the reservation information holding unit 124. At this time, the determination unit 114 registers the schedule information with the charging state as “waiting for charging”.

  Returning to FIG. 9, the management unit 116 controls the first transport device 56, the second transport device 58, and the lifting device 94 to move a predetermined pallet to the passenger compartment 12 or the specific parking space 50. The management unit 116 determines the movement of the pallet in the mechanical parking lot 10 required for the movement of the pallet using a known puzzle operation algorithm. At this time, if there is a charging pallet being charged, the movement of the charging pallet is prohibited, and a puzzle operation for moving a pallet other than the pallet being charged is determined. The management unit 116 transmits a command to the first transport device 56, the second transport device 58, and the lifting device 94 so that the determined movement of the pallet is realized.

  When receiving the warehousing request signal, the management unit 116 moves an empty pallet on which no vehicle is loaded to the passenger compartment 12. The management unit 116 refers to the vehicle information holding unit 122 to confirm the type of vehicle corresponding to the vehicle management number included in the warehousing request signal, and selects either the normal pallet 32 or the charging pallet 100. When the vehicle is an EV vehicle and the position information of the power supply port is registered, the charging pallet 100 provided with the outlet on the side corresponding to the position of the power supply port is selected. When the management unit 116 receives the warehousing instruction signal, the management unit 116 moves the pallet loaded with the vehicle to a predetermined parking space.

  When the charging space becomes empty, the management unit 116 refers to the reservation information holding unit 124, moves the charging pallet to be charged to the empty charging space, and starts charging. When there are empty spaces in the plurality of charging spaces, the charging spaces are accommodated in a charging space near the parking space where the charging pallet is accommodated. Further, the charging state of the schedule information corresponding to the charging pallet for starting charging is changed to “charging”.

  The management unit 116 checks whether there is a charging pallet that should be charged periodically when the charging space is continuously available, and if there is a charging pallet that satisfies the condition, Start charging. The time interval for periodically checking is, for example, 5 minutes. Further, in addition to the periodic confirmation timing, the charging pallet to be charged is confirmed at the timing when entering / exiting the mechanical parking lot 10 or changing the reservation time.

  The management unit 116 checks whether there is a charging pallet waiting for charging whose scheduled time held in the reservation information holding unit 124 is after the current time. If there is a charging pallet that satisfies the condition, the management unit 116 charges the charging pallet. The charging pallet to be started. At this time, when there are a plurality of charging pallets that satisfy the condition, the charging pallet with the old scheduled time is prioritized.

  On the other hand, when there is no charging pallet waiting for charging whose scheduled time is held after the current time in the reservation information holding unit 124, the management unit 116 starts the charging start time for the charging pallet whose reservation mode is “timely charging”. Check whether it is possible to move forward. Since the scheduled time determined at the time of warehousing and the actual time actually charged are not necessarily the same, there is a possibility that the charging space becomes empty earlier than planned. In addition, when a vehicle waiting for charging is discharged without being charged, a charging space is vacated during the time zone reserved for the vehicle. In such a case, the charge start time is advanced in advance for the charge reservation in the timely charge mode in which the charge start time is not specified so that the charge is started earlier. When a plurality of schedule information can be advanced, the schedule information with the old warehousing time is preferentially advanced.

  FIG. 12 is a diagram schematically showing a schedule when the charge reservation is carried out in advance. The upper part of the figure shows the schedule of the charging space B before the reservation is advanced, and the lower part shows the result after the advance. In the schedule before the advance, since the scheduled time of 5 hours from 17:10 of the start time is set as the schedule information with the pallet number “2”, the charging space B is scheduled to be vacant at 22:10. . In the results shown in the lower part, charging of the charging pallet with the pallet number “2” is completed at 21:40, which is earlier than planned, and the charging space B is in an empty state from 21:40.

  Since there is no charging pallet waiting for charging whose scheduled time is after the current time at 21:40, the management unit 116 has a pallet whose reservation pattern is “timely charging” and schedule information for “waiting for charging”. Confirm whether the numbers “4” and “5” can be moved forward. In the schedule information for pallet numbers “4” and “5”, 1 hour is set as the scheduled time, so the schedule is advanced to 23:00 when charging of the pallet for “3” is started. Judge that it is possible. Since the management unit 116 gives priority to the advance of the schedule information with the old warehousing time, the schedule information for the pallet number “4” with the old warehousing time is advanced to charge the charging pallet with the pallet number “4” to start charging. A palette is used.

  When the charging of the vehicle accommodated in the charging space is completed, the management unit 116 moves the charging pallet to the outside of the charging space and stores it in a predetermined parking space. In addition, the charging state of the schedule information corresponding to the charging pallet that has been charged is changed to “charged”.

Whether or not the charging of the vehicle is completed is determined based on the current value of the power supplied by the power feeding device 42, the actual time when the charging is performed, or the like. For example, when it is determined that charging is completed according to time, charging ends when the actual time of charging exceeds a specific charging upper limit time. As a result, the charging is prevented from continuing significantly exceeding the originally scheduled time. The charging upper limit time is calculated by the following formula.
(Charging upper limit time) = (scheduled time) x (coefficient) + (room time)
Here, the scheduled time is a scheduled time held in the reservation information holding unit 124, and is a value set for each charging pallet. The coefficient and the margin time are values that are uniformly set in advance regardless of the vehicle. The coefficient is a value set to make the charging upper limit time proportional to the scheduled time, and a value of 1 or more is set. For example, it may be 1.1 or 1.5. The allowance time is a time that is uniformly added, and may be, for example, about 5 to 30 minutes.

  When the management unit 116 receives the delivery request signal, the management unit 116 moves the pallet loaded with the vehicle corresponding to the vehicle management number included in the delivery request signal to the passenger compartment 12. Thereafter, when the vehicle moves out of the passenger compartment 12 and the pallet for charging in the passenger compartment 12 does not carry the vehicle and the delivery is confirmed, the management unit 116 sets the corresponding schedule information from the reservation information holding unit 124. Is deleted.

  When the vehicle requested to leave is being charged, the management unit 116 stops charging the vehicle and moves the charging pallet to the passenger compartment 12. At this time, the management unit 116 changes the charging state of the schedule information corresponding to the charging pallet for which charging has been suspended to “charging interruption”, and temporarily secures a charging space for the charging pallet for which charging has been suspended. To do. For example, another charging pallet is temporarily prohibited from starting charging in a charging space in which the charging pallet is accommodated. This is to allow charging to be resumed immediately after re-entry when the charging pallet that has been interrupted is re-entry.

  On the other hand, when the delivery is confirmed for the charging pallet for which charging is interrupted, the temporarily secured charging space is released so that the charging pallet waiting for charging can be used. In addition, even if the charge reservation setting is changed at the time of re-entry, the temporarily reserved charging space is released. This is because, since a new charge reservation is set, it may not be necessary to resume charging in preference to other charging pallets waiting for charging.

  Returning to FIG. 9, when the detection unit 118 receives a signal from a seismometer provided in the parking room and detects a predetermined shake due to an earthquake or the like, the power from the power supply device 42 to the charging pallet is detected for safety. Stop supplying. This is because, when shaking occurs during charging, the power receiving terminal that contacts the power feeding terminal may temporarily come off while current is flowing. In addition, when the detected maximum value of the shake is less than a predetermined value and the shake has stopped, the power supply from the power supply device 42 that has been stopped to the charging pallet may be resumed.

Operation | movement of the mechanical parking lot 10 by the above structure is demonstrated.
FIG. 13 is a flowchart showing the flow of the charge reservation process. When a vehicle is received (S10) and a reservation for charging the vehicle is made (Y in S12), the scheduled time for charging is confirmed (S14). When the charging start time is designated (Y in S16), it is confirmed whether there is a charging space vacant schedule at the designated starting time (S18). When there is an empty charging space schedule (Y in S18), schedule information is registered as a reserved charging pattern (S20). When there is no vacant space in the designated start time (N in S18), an alternative time that can secure the charging space is searched for and presented (S22). When the presented alternative time is designated as the charging start time (Y in S24), schedule information is registered as a reserved charging pattern (S20).

  When the charging start time is not specified (N in S16) or when the alternative time is not specified as the charging start time (N in S24), the vacant schedule for the charging space is confirmed to determine the scheduled charging start time. (S26), schedule information is registered as a timely charging pattern (S28). If the vehicle is not reserved for charging (N in S12), the steps after S14 are skipped.

  FIG. 14 is a flowchart showing a flow of processing for starting charging of the charging pallet. It is confirmed whether the scheduled time is after the current time and there is schedule information waiting for charging. If there is schedule information that exceeds the scheduled time (Y in S32), the schedule is selected from the charging pallets corresponding to the schedule information. Charging is started by moving the charging pallet with the old time to the charging space (S34).

  When there is no schedule information exceeding the scheduled time (N in S32), it is confirmed whether there is schedule information waiting for charging in a timely charge pattern (S36). If the charging pattern is timely and there is schedule information waiting for charging (Y in S36), it is confirmed whether the charging start time can be advanced by confirming the vacant schedule of the charging space (S38). If the start time can be advanced (Y in S38), among the charging pallets corresponding to the schedule information that can be advanced, the charging pallet with the old storage time is moved to the charging space and advanced from the scheduled time. To start charging (S40). If the timely charging pattern is present and there is no schedule information waiting for charging (N in S36), or if the charging start time cannot be advanced (N in S38), this flow ends.

  FIG. 15 is a flowchart showing a flow of processing for leaving a vehicle. When a vehicle exit instruction is received (S50), it is confirmed whether the exit instruction target vehicle is being charged (S52). If charging is in progress (Y in S52), the charging of the vehicle is interrupted and the charging state is changed to "charging interruption" (S54), and the charging space used for charging the vehicle is temporarily prepared for re-entry. (S56). If the vehicle is not being charged (N in S52), steps S54 and S56 are skipped.

  When the vehicle instructed to leave is re-stocked (Y of S58), the setting of the charge reservation is not changed at the time of re-stocking (Y of S60), and the charge state is “Charge interruption” ( (Y of S62), the vehicle is moved to the charging space temporarily secured (S64), and charging is resumed (S66). When the state of charge is not “charge interruption” (N in S62), the vehicle to be re-stocked is moved to a predetermined parking space. When the setting of the charge reservation is changed at the time of re-entry (N in S60), the schedule information of the charge reservation is updated (S68) and moved to a predetermined parking space (S70). When the vehicle instructed to leave moves out of the passenger compartment and the departure is confirmed (N in S58), if there is a temporarily reserved charging space as the exit confirmation process, it is released. The charging reservation schedule information corresponding to the vehicle is cleared (S72).

  In the mechanical parking lot 10 according to the present embodiment, it is possible to make a reservation for charging by specifying a charging start time when an EV car is stored, so the vehicle is charged in a time zone according to the user's request. be able to. In addition, even if the charging start time is not specified, the earliest possible time for starting charging is determined at the time of warehousing. Charging can be started at a time earlier than the time.

  In addition, when there is no plan to vacate the charging space at the specified charging start time, an alternative time is searched for and presented. Save time and effort.

  In the mechanical parking lot 10 according to the present embodiment, in accordance with the vacant schedule of the charging space, the vehicle whose charging start time is not specified is started earlier than the scheduled time determined at the time of warehousing. Charging can be started at the time. In addition, for vehicles for which the charging start time is designated, charging can be started at the designated scheduled time because the charging start time is not advanced. Thereby, while charging to a vehicle in the time slot | zone according to a user's request | requirement, about the vehicle without time specification, it can charge earlier. In addition, by efficiently using the limited charging space, it is possible to prevent the vacant schedule of the charging space from being lost and widen the time period during which reserved charging can be performed.

  In the mechanical parking lot 10 according to the present embodiment, when the pallet is moved based on a predetermined puzzle operation, the movement of the charging pallet during charging is prohibited, and the other charging pallets are moved. As a result, the charging pallet that is being charged is moved along with the puzzle operation to prevent the suspension and resumption of charging of the vehicle from being repeated, and the influence on the battery life due to repeated interruption and resumption of charging is suppressed. be able to.

  Further, since the charging space is provided at a position farthest from the hoistway 96, even if the movement of the charging pallet during charging is prohibited, the restriction for obtaining the solution of the puzzle operation for moving other pallets It is hard to become. In addition, even if there is a restriction that prohibits movement of the charging pallet during charging, the number of times of movement in the puzzle operation is less likely to increase compared to the case where there is no restriction, so that the time it takes to enter and exit is longer. Can be suppressed. Thereby, it can prevent that a user's convenience falls.

  On the other hand, when an instruction to leave the vehicle is being charged, the charging to the vehicle is interrupted and issued, and the charging space in which the vehicle is accommodated is temporarily reserved for re-entry. deep. Thereby, it is possible to prevent the charge reservation from being reset when the charge is interrupted and re-stocked, so that the charge start time becomes later than originally scheduled. Therefore, even if it is necessary to call the vehicle to the passenger compartment temporarily, it is possible to charge the vehicle according to the original schedule determined when the vehicle enters the parking lot, and the convenience for the user can be improved.

  In the mechanical parking lot 10 according to the present embodiment, the charging upper limit time is calculated using a uniformly set coefficient and margin time, and charging is terminated when the actual charging time exceeds the charging upper limit time. As a result, it is possible to prevent the vehicle from being charged significantly beyond the originally scheduled time, and the start of charging the subsequent vehicle from being significantly delayed from the scheduled time. In addition, because the upper limit charging time can be calculated according to the scheduled time that varies depending on the type of vehicle and the charging method based on the uniformly set value, the upper limit time suitable for each vehicle can be calculated with a relatively simple control method. Can be imposed. In addition, overcharging of the vehicle can be prevented.

  In the mechanical parking lot 10 according to the present embodiment, when a predetermined shake due to an earthquake or the like is detected, the power supply from the power supply device 42 to the charging pallet is stopped. Thereby, it is possible to prevent the power supply unit 44 and the power receiving unit 104 from being temporarily disconnected when power is supplied from the power supply device 42, and safety can be improved.

(Second Embodiment)
FIG. 16 is a block diagram illustrating functions and configurations of the control device 30 according to the second embodiment. The mechanical parking lot 10 according to the second embodiment is different from the first embodiment in that the holding unit 120 of the control device 30 further includes a permission attribute holding unit 126. The permission attribute holding unit 126 holds a correspondence relationship between a charging space and a charging pallet that permits charging in the charging space. For example, in a charging space where a power supply device that supports rapid charging is installed, Only pallets that support charging are accommodated. Hereinafter, the description will focus on differences from the first embodiment, and description of common points will be omitted.

  FIG. 17 is a diagram illustrating an example of permission attribute information held by the permission attribute holding unit 126. The permission attribute holding unit 126 holds permission attribute information indicating a relationship between a charging space and attribute information of a charging pallet that permits charging in the charging space. This figure shows a state where the permission attribute “α” is set in the charging space A and the permission attribute “β” is set in the charging space B among the two charging spaces A and B.

  FIG. 18 is a diagram illustrating an example of attribute information held in the reservation information holding unit 124. In the present embodiment, attribute information is further set as schedule information held by the reservation information holding unit 124. The attribute information is set for each charging pallet as information indicating the type of pallet. In this figure, among a plurality of charging pallets, the attribute information “α” is set for the charging pallets with the pallet numbers “1” and “2”, and the attribute information is set for the charging pallets with the pallet numbers “3” to “7”. A state in which “β” is set is shown.

  The management unit 116 refers to the permission attribute holding unit 126 and permits charging only a charging pallet having a specific attribute in a specific charging space, and prohibits charging to a charging pallet having other attributes. Since “α” is set as the permission attribute for charging space A, only charging pallets with pallet numbers “1” and “2” whose attribute information is “α” are allowed to be charged in charging space A. The charging pallets with the pallet numbers “3” to “7” are prohibited from being charged in the charging space A, and instead are allowed to be charged in the charging space B having the same permission attribute.

  When determining the scheduled start time for charging, the determination unit 114 confirms the vacant schedule of the charging space in which the permission attribute corresponding to the attribute information attached to the charging pallet is set. For example, when determining the scheduled time of the pallet number “1”, the scheduled time is determined by confirming the vacant schedule of the charging space A. Even when designation of the charging start time is received, reserved charging is accepted only when charging space A is available. If there is no free space in the charging space A, even if there is a free space in the charging space B at the specified time, the charging space A is checked for a free space, and an alternative time is searched and presented to the user.

  For example, when “α” is attribute information indicating that quick charging is supported and “β” is attribute information indicating that normal charging is supported, the charging space provided with the power feeding device 42 that supports quick charging is used. The permission attribute “α” is set, and “β” is set for a charging space that is not. Similarly, attribute information “α” is set for a charging pallet corresponding to quick charging, and attribute information “β” is set for a charging pallet that is not. In this way, by setting the correspondence relationship between the charging space and the charging pallet and directing only the charging pallet satisfying the correspondence relationship to the specific charging space, even when different types of power feeding devices are provided, Can be managed as a whole. Moreover, the charge reservation for quick charge and the charge reservation for normal charge can be managed separately, and the convenience can be improved.

  In addition, the attribute information for parking subscribers is set to “α”, and the attribute information for temporary users is set to “β”, so that there is a difference in the charging space and charging pallet that each user can use. Can be managed. In this case, the charging space A is a dedicated space for subscribers, and a dedicated charging pallet is prepared according to the number of subscribers. A person can use a dedicated space.

  The attribute information may be set according to the type of vehicle loaded on the pallet. For example, when a regular contractor's vehicle with a registered vehicle management number is received, “α” is set as attribute information at the time of storage, and a temporary user's vehicle with no registered vehicle management number is registered. In the case of warehousing, “β” is set as attribute information. Also in this case, the regular contractor's vehicle in which “α” is set as the attribute information can use a dedicated space.

  The attribute information may be set according to the vehicle management number of the vehicle loaded on the pallet. For example, the permission given to the occupied space only on the charging pallet loaded with the occupied vehicle associated with the specific vehicle management number so that only a specific occupied vehicle can use a predetermined charging space designated as the occupied space The attribute is set. For example, the permission attribute of the charging space A is “γ”, and the attribute information of the charging pallet is “γ” only when the occupied vehicle is loaded. Thereby, vehicles other than the occupied vehicle cannot be charged in this charging space, and the occupied vehicle can always use the specific charging space.

  The configuration and operation of the mechanical parking lot according to the embodiment have been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements, and such modifications are also within the scope of the present invention.

Moreover, you may apply the preset scheduled time irrespective of the classification of a vehicle.

  In the embodiment, the charging reservation is instructed through the touch panel provided on the operation panel, but the method of instructing the control device is not limited to this. For example, a charging reservation Web page may be prepared and a charging reservation may be made from outside the control device via a network such as the Internet. Further, it is also possible to confirm the vacant schedule of the charging space, the scheduled start time of charging of each vehicle, and the like by inquiry from the Web page.

  In the embodiment, one attribute information is set for one charging space as a permission attribute, but a plurality of attribute information may be set. For example, both “α” and “β” may be set as permission attributes to be set in the charging space B. Further, the permission attribute may be set by combining the attribute information set according to the type of the pallet and the attribute information set according to the type of the vehicle loaded on the pallet.

  In the embodiment, the charging space 52 is arranged at a position farthest from the hoistway 96, but may be arranged at other positions. In this case, it is desirable to set the position where there is little need to move when determining the puzzle operation of the pallet. For example, a rectangular parking room may be provided at the four corners. Further, when a pillar or a wall is provided in the parking room, there is only one adjacent parking space, and a position that is a dead end may be used as a charging space.

  In the embodiment, the so-called underground mechanical parking lot 10 in which the passenger compartment is located at the upper end of the hoistway has been described. However, the present invention is not limited to this, and when the passenger compartment is located at the lower end of the hoistway, It can also be applied to the case where a boarding / exiting room is provided in the middle. Moreover, although the example where the mast is installed as the support at the four corners of the hoistway has been described, the structures of the hoistway and the hoisting device other than those exemplified as the embodiment may be used.
