[0007] Problems to be Solved by the Invention

[0008] In an apartment or a large facility, there are sometimes multiple parking lots. In such a case, there are situations where management related to entry and exit and management related to charging processing are performed separately for each parking lot and situations where the above management is performed collectively for all parking lots. In such various management situations, a technology for achieving cooperation and appropriately performing storage management and charging management is required.

[0009] The present invention has been completed in view of the above circumstances, and an object thereof is to provide a storage management system and a storage management method capable of achieving cooperation and appropriately performing storage management and charging management for a plurality of storage facilities provided with charging equipment.

[0010] Means for Solving the Problems

[0011] The repository management system of the present invention for achieving the above object includes: a plurality of repository management devices that respectively manage a plurality of repositories, wherein each of the repositories has a plurality of storage spaces and chargers provided in the storage spaces; and a power management device connected to the plurality of repository management devices. Each of the plurality of repository management devices includes: a first in-out processing unit that determines whether an item to be stored can be stored in a repository to be managed when a request for storing an item in the repository is generated; a first power distribution request unit that, when determining that the item determined by the first in-out processing unit to be storable is an item to be charged during the storage request, sends a power distribution request related to the item to the power management device; and a charger control unit that, when obtaining a power distribution permission notification sent from the power management device in response to the power distribution request sent by the first power distribution request unit, switches the charger provided in the storage space where the item is stored to a power supply-enabled state. The power management device includes: an available power amount storage unit that stores the upper limit value of the power amount that can be used simultaneously in the plurality of repositories, i.e., available power amount information; a power amount in use storage unit that stores information on the power amount currently being used in the plurality of repositories, i.e., power amount in use information; a power distribution determination unit that, when receiving the power distribution request from any one of the repository management devices, determines whether power can be distributed to the received request based on the available power amount information stored in the available power amount storage unit and the power amount in use information stored in the power amount in use storage unit; and a determination result notification unit that, when the power distribution determination unit determines that power can be distributed to the received request, generates a power distribution permission notification related to the item and sends it to the corresponding repository management device.

[0012] In addition, the repository management system of the present invention is communicably connected to a plurality of repository management devices that respectively manage a plurality of repositories. Among them, the plurality of repositories have a plurality of storage spaces and chargers provided in the storage spaces. The repository management system includes: an available power amount storage unit that stores, for each of the plurality of repositories, an upper limit value of the power amount that can be used simultaneously, that is, available power amount information; a power amount in use storage unit that stores, for each of the plurality of repositories, information on the power amount currently in use, that is, power amount in use information; a power distribution determination unit that, when there is an item for which it is requested to be stored and charged in any one of the plurality of repositories to be managed, determines, based on the available power amount information stored in the available power amount storage unit and the power amount in use information stored in the power amount in use storage unit, the repository to which power can be distributed for the item; and a second in-out processing unit that determines, from among the repositories determined by the power distribution determination unit as being able to distribute power for the item, the repository to be the storage destination for the item, and sends an inbound notice and a power distribution permission notice related to the item to the repository management device corresponding to the determined repository.

[0013] In addition, in the repository management method of the present invention, the repository management system includes: a plurality of repository management devices that respectively manage a plurality of repositories, where the repositories have a plurality of storage spaces and chargers provided in the storage spaces; and a power management device that is connected to the plurality of repository management devices and stores the upper limit value of the power amount that can be used simultaneously in the plurality of repositories, that is, available power amount information, and the information on the power amount currently in use in the plurality of repositories, that is, power amount in use information. The plurality of repository management devices respectively perform the following processes: when there is an item for which it is requested to be stored in a repository to be managed, determine whether the item can be stored; and when the item determined to be able to be stored is determined to be an item for which it is requested to be charged during storage, send a power distribution request related to the item to the power management device. When the power management device receives the power distribution request from any one of the repository management devices, it determines whether it can distribute power for the received request based on the stored available power amount information and power amount in use information. When the power management device determines that it can distribute power for the received request, it generates a power distribution permission notice related to the item and sends it to the corresponding repository management device. The repository management device among the plurality of repository management devices that has received the power distribution permission notice sent from the power management device in response to the sending of the power distribution request switches the charger provided in the storage space storing the item to a power supply available state.

[0027] Hereinafter, taking a parking lot management system as an example, several embodiments of the storage management system of the present invention will be described. As described below, the parking lot management system includes a plurality of parking lot management devices as an example of a plurality of storage management devices and a power management device connected to the plurality of parking lot management devices. Each parking lot management device manages a parking lot as an example of a storage. An electric vehicle, which is an example of an object to be stored, is parked in the parking lot.

[0028] <<First Embodiment>>

[0029] 〈Structure of Parking Lot Management System〉

[0030] Figure 1 This is an overall view showing the structure of a parking lot management system 1A according to the first embodiment of the present invention. The parking lot management system 1A includes various devices provided in four parking lots, namely, the first parking lot 10, the second parking lot 20, the third parking lot 30, and the fourth parking lot 40, a first parking lot management device 100A that manages the first parking lot 10, a second parking lot management device 200A that manages the second parking lot 20, a third parking lot management device 300A that manages the third parking lot 30, a fourth parking lot management device 400A that manages the fourth parking lot 40, and a power management device 50A.

[0031] The first parking lot 10 is a mechanical parking lot. The first parking lot 10 has: a plurality of shelves 11 as parking spaces; pallets 12 provided on each shelf 11 as carriers for loading and unloading vehicles; chargers 13 provided on each pallet 12; an entrance / exit 14; an operation panel 15 provided near the entrance / exit 14; and a driving device 16 that moves the pallet 12 between the corresponding shelf 11 and the entrance / exit 14. In Figure 1 it, the case where the number of shelves 11 in the first parking lot 10 is 8 is shown, but the number of shelves 11 is not limited to 8 and may be 1 to 7 or 9 or more.

[0032] Figure 2It is a block diagram showing the detailed structures of the first parking lot management device 100A to the fourth parking lot management device 400A and the power management device 50A.

[0033] The first parking lot management device 100A includes a first storage unit 110, a first communication unit 120, and a first CPU 130A. The first storage unit 110 has a first shelf information storage unit 111 as a first storage space information storage unit, which stores shelf information indicating whether there is a vehicle currently in each shelf 11 as storage space information. The first communication unit 120 communicates with the power management device 50A.

[0034] The first CPU 130A includes a first in-out processing unit 131, an operation control unit 132, a first power distribution request unit 133, and a charger control unit 134.

[0035] If the first in-out processing unit 131 detects, based on the operation information from the operation panel 15, that a vehicle has requested to enter the first parking lot 10, it determines whether the vehicle can enter the first parking lot 10 based on the shelf information stored in the first shelf information storage unit 111.

[0036] The operation control unit 132 controls the equipment in the first parking lot 10, specifically, the opening and closing of the driving device 16 and the doors (not shown) of the in-out ports 14. The first power distribution request unit 133 sends a power distribution request related to the electric vehicle to the power management device 50A when it determines that the vehicle determined by the first in-out processing unit 131 to be able to enter the warehouse is an electric vehicle equipped with a battery and requesting charging after entering (i.e., after entering the warehouse).

[0037] The charger control unit 134 switches the charger 13 provided on the shelf 11 where the electric vehicle is stored to the power supply enabled state when it obtains a power distribution permission notice sent from the power management device 50A in response to the power distribution request sent by the first power distribution request unit 133.

[0038] The second parking lot 20, the third parking lot 30, and the fourth parking lot 40 have the same structure as the first parking lot 10, so detailed descriptions are omitted.

[0039] The power management device 50A includes a second storage unit 51A, a second communication unit 52, and a second CPU 53A. The second storage unit 51A includes an available power amount storage unit 511A and a used power amount storage unit 512A. The available power amount storage unit 511A stores the upper limit value of the power amount that can be used simultaneously in the first parking lot 10 to the fourth parking lot 40, that is, the available power amount information. The used power amount storage unit 512A stores the information on the power amount currently being used in the chargers in the first parking lot 10 to the fourth parking lot 40, that is, the used power amount information.

[0040] The second communication unit 52 communicates with the first parking lot management device 100A of the first parking lot 10, the second parking lot management device 200A of the second parking lot 20, the third parking lot management device 300A of the third parking lot 30, and the fourth parking lot management device 400A of the fourth parking lot 40.

[0041] The second CPU 53A has a power distribution determination unit 531A and a determination result notification unit 532A. The power distribution determination unit 531A acquires a power distribution request from any one of the parking lot management devices, and determines whether power distribution can be performed for the acquired request based on the available power amount information stored in the available power amount storage unit 511A and the in-use power amount information stored in the in-use power amount storage unit 512A.

[0042] When the power distribution determination unit 531A determines that power distribution can be performed for the acquired request, the determination result notification unit 532A generates a power distribution permission notification related to the electric vehicle and sends it to the corresponding parking lot management device. In addition, when the power distribution determination unit 531A determines that power distribution cannot be performed for the acquired request, the determination result notification unit 532A generates a non-permission power distribution notification related to the electric vehicle and sends it to the corresponding parking lot management device.

[0043] <Operation of the Parking Lot Management System>

[0044] As an example of the operation of the parking lot management system 1A of the present embodiment, the processing executed when the electric vehicle E0 enters the first parking lot 10 will be described.

[0045] In the present embodiment, in the available power amount storage unit 511A of the power management device 50A, the number of electric vehicles that can be charged simultaneously in the entire first parking lot 10 to the fourth parking lot 40 is stored as the available power amount information. In the present embodiment, this number is 12.

[0046] As Figure 1As shown, before the electric vehicle E0 enters the warehouse, the electric vehicles E1 to E10 and the ordinary vehicles C1 to C6 that are not electric vehicles are parked in any one of the first parking lot 10 to the fourth parking lot 40. Specifically, 6 electric vehicles E1 to E6 are stored in the first parking lot 10 and are in the charging state. 2 electric vehicles E7 and E8 are stored in the second parking lot 20 and are in the charging state, and 1 ordinary vehicle C1 that is not an electric vehicle is stored. 2 electric vehicles E9 and E10 are stored in the third parking lot 30 and are in the charging state, and 3 ordinary vehicles C2, C3, and C4 are stored. 2 ordinary vehicles C5 and C6 are stored in the fourth parking lot 40. That is, within the first parking lot 10 to the fourth parking lot 40, a total of 10 electric vehicles E1 to E10 are in the charging state. In the in-use power storage unit 512A, as the in-use power amount information, the number of electric vehicles currently being charged, that is, "10 vehicles", is stored.

[0047] Figure 3 It is a sequence diagram showing the actions executed within the parking lot management system 1A of the present embodiment. First, if the user of the electric vehicle E0 uses the operation panel 15 in the first parking lot 10 to perform an operation to request the entry of the electric vehicle E0, the first in-out processing unit 131 of the first parking lot management device 100A acquires the corresponding operation information and detects that an entry request vehicle for the first parking lot 10 has occurred (in step S1, "Yes").

[0048] If the first in-out processing unit 131 detects that an entry request vehicle has occurred in the first parking lot 10, it determines whether the electric vehicle E0 as the entry request vehicle can enter the first parking lot 10 based on the shelf information stored in the first shelf information storage unit 111 (step S2).

[0049] Currently, in the first parking lot 10, as Figure 1 shown, 2 out of the 8 shelves 11 are in the idle state. The first in-out processing unit 131 identifies the idle shelves 11 based on the shelf information and determines that the electric vehicle E0 can enter the first parking lot 10 (in step S2, "Yes"). When the first in-out processing unit 131 determines that the electric vehicle E0 can enter the first parking lot 10, the motion control unit 132 controls the drive device 16 to move the pallet 12 on which the electric vehicle E0 is to be loaded to the in-out port 14 and opens the door of the in-out port 14.

[0050] The user moves the electric vehicle E0 onto the pallet 12, gets off, and connects the charger 13 to the electric vehicle E0 with a cable in order to charge during parking. And if the user uses the operation panel 15 to perform an operation to indicate closing the door, the motion control unit 132 closes the door of the in-out port 14 based on this operation.

[0051] The movement control unit 132 moves the pallet 12 loaded with the electric vehicle E0 from the loading / unloading port 14 to the shelf 11 at the storage destination (step S3). When the pallet 12 reaches the predetermined shelf 11, the charger 13 is installed on the power supply device (not shown) in the first parking lot 10.

[0052] In addition, if the first power distribution request unit 133 determines that the electric vehicle E0 determined by the first loading / unloading processing unit 131 to be able to be stored is an electric vehicle equipped with a battery and determines that it is a vehicle requesting charging during storage ( "Yes" in step S4), the first power distribution request unit 133 sends a power distribution request regarding the electric vehicle E0 to the power management device 50A (step S5). The first power distribution request unit 133 may also send a power distribution request to the power management device 50A when the electric vehicle E0 is an electric vehicle and the user of the electric vehicle E0 performs an operation indicating charging processing during parking.

[0053] In the power management device 50A, the power distribution determination unit 531A acquires the power distribution request sent from the first parking lot management device 100A, and determines whether power can be distributed to the acquired request based on the available power amount information stored in the available power amount storage unit 511A and the in-use power amount information stored in the in-use power amount storage unit 512A (step S6).

[0054] Here, the power distribution determination unit 531A determines that the number of electric vehicles currently being charged, which is the in-use power amount information stored in the in-use power amount storage unit 512A, is "10", and has not reached the number of electric vehicles that can be charged simultaneously, which is the available power amount information stored in the available power amount storage unit 511A, which is "12", and power can be distributed to the electric vehicle E0.

[0055] When the power distribution determination unit 531A determines that power can be distributed to the electric vehicle E0, it generates a power distribution permission notice as a distribution determination result notice related to the electric vehicle E0. The determination result notice unit 532A sends the generated power distribution permission notice to the corresponding first parking lot management device 100A (step S7).

[0056] In the first parking lot management device 100A, the charger control unit 134 acquires the power distribution permission notice sent from the power management device 50A ( "Yes" in step S8). When the charger control unit 134 acquires the power distribution permission notice, it switches the charger 13 provided on the shelf 11 where the electric vehicle E0 is stored to the power supply available state. Specifically, the charger control unit 134 switches the power supply device on which the corresponding charger 13 is installed to the on state (step S9).

[0057] When the first in-out processing unit 131 determines that the electric vehicle E0 cannot enter the first parking lot 10 (No in step S2), it does not perform the entry processing and returns to step S1.

[0058] In addition, when the first power distribution request unit 133 determines that the vehicle requesting entry is not an electric vehicle equipped with a storage battery (No in step S4), it does not make a power distribution request and ends the process.

[0059] In addition, when the charger control unit 134 obtains a power non-distributable notice (No in step S8), it does not perform the process of switching to the power supply available state and ends the process.

[0060] When there is a vehicle requesting entry to the second parking lot 20, the third parking lot 30, or the fourth parking lot 40, the same processing as steps S1 to S9 described above is also executed.

[0061] According to the above first embodiment, regarding multiple parking lots provided with charging facilities, it is possible to determine whether entry is possible for each parking lot and perform entry management, and also manage the charging facilities of multiple parking lots together to determine whether charging is possible. Thus, regarding the entire multiple parking lots, even when an upper limit value of the power consumption is set according to the contract power amount, it is possible to appropriately determine whether entry is possible and whether charging is possible respectively at the time of entry.

[0062] In the above first embodiment, the following situation was described: the number of electric vehicles that can be charged simultaneously is stored in the available power amount storage unit 511A as available power amount information, the number of electric vehicles currently being charged is stored in the in-use power amount storage unit 512A as in-use power amount information, and when the number of electric vehicles currently being charged does not reach the number of electric vehicles that can be charged simultaneously, the power distribution determination unit 531A determines that the electric vehicle E0 to be entered can be charged. However, it is not limited to this processing. It may also be that the available power amount storage unit 511A stores the upper limit value of the power amount (kW) that can be used simultaneously as available power amount information, the in-use power amount storage unit 512A stores the total power consumption (kW) of the currently allocated charging as in-use power amount information, and if the value obtained by subtracting the total power consumption (kW) of the currently allocated charging from the upper limit value of the power amount (kW) that can be used simultaneously is greater than the power consumption used for charging the electric vehicle E0 to be entered, the power distribution determination unit 531A determines that charging of the electric vehicle E0 to be entered can be performed.

[0063] By determining whether power can be distributed in this way, it is possible to appropriately make a determination even when the output power amount during charging varies depending on the electric vehicle.

[0064] Second Embodiment

[0065] <Structure of Parking Lot Management System>

[0066] Figure 4 This is an overall view showing the structure of a parking lot management system 1B according to the second embodiment of the present invention. The parking lot management system 1B of the second embodiment has the same structure as the parking lot management system 1A described in the first embodiment, except that it has a first parking lot management device 100B, a second parking lot management device 200B, a third parking lot management device 300B, a fourth parking lot management device 400B, and a power management device 50B instead of the first parking lot management device 100A, the second parking lot management device 200A, the third parking lot management device 300A, the fourth parking lot management device 400A, and the power management device 50A. Therefore, the detailed description of the parts with the same functions is omitted.

[0067] Figure 5 This is a block diagram showing the detailed structure of the first parking lot management device 100B to the fourth parking lot management device 400B and the power management device 50B. The power management device 50B has a second storage unit 51B and a second CPU 53B.

[0068] In addition to having the structure of the second storage unit 51A, the second storage unit 51B also has an allocation waiting information storage unit 513B. The allocation waiting information storage unit 513B stores the power allocation waiting information described later according to the instruction of the second CPU 53B.

[0069] The second CPU 53B has a power allocation determination unit 531B and a determination result notification unit 532B. When the power allocation determination unit 531B determines that power allocation cannot be performed for the obtained power allocation request, it generates power allocation waiting information related to the corresponding electric vehicle and stores it in the allocation waiting information storage unit 513B. When the power allocation determination unit 531B determines that the current power consumption has decreased because charging of a certain electric vehicle has been completed in a certain parking lot and power allocation can be performed for the electric vehicle corresponding to the power allocation waiting information stored in the allocation waiting information storage unit 513B, it sends the determination result to the determination result notification unit 532B and deletes the power allocation waiting information stored in the allocation waiting information storage unit 513B.

[0070] When the power allocation determination unit 531B determines that power allocation can be performed for the electric vehicle corresponding to the power allocation waiting information, the determination result notification unit 532B generates a power allocation permission notification related to the electric vehicle and sends it to the corresponding parking lot management device.

[0071] <Operation of Parking Lot Management System>

[0072] As an example of the operation of the parking lot management system 1B of the present embodiment, the processing executed when the electric vehicle E0 enters the first parking lot 10 will be described.

[0073] In the present embodiment, in the available power amount storage unit 511B of the power management device 50B, the number of electric vehicles that can be charged simultaneously, "12 vehicles", is stored as the available power amount information.

[0074] In addition, before the electric vehicle E0 enters the warehouse, as Figure 4 shown, electric vehicles E1 to E10 are stored in the first parking lot 10 to the fourth parking lot 40 in the same manner as in the first embodiment, and are being charged, and ordinary vehicles C1 to C6 are stored. In addition to this, charged vehicles E11 and E12 are stored in the fourth parking lot 40 and are being charged. Moreover, an electric vehicle E13 is stored in the first parking lot 10, and an electric vehicle E14 is stored in the second parking lot 20, and these electric vehicles E13 and E14 are in a charging waiting state.

[0075] With such a storage state, the number of currently charged electric vehicles, "12 vehicles", is stored in the in-use power amount storage unit 512B as the in-use power amount information.

[0076] In addition, in the allocation waiting information storage unit 513B, the information of the electric vehicle E13 is stored as the power waiting information of the first parking lot 10, and the information of the electric vehicle E14 is stored as the power waiting information of the second parking lot 20.

[0077] As described above, various information is stored in the power management device 50B. When the user of the electric vehicle E0 operates the operation panel 15 of the first parking lot 10 to request the electric vehicle E0 to enter the warehouse while vehicles are stored in each parking lot, the corresponding first parking lot management device 100B performs the same processing as steps S1 to S5 described in the first embodiment, and sends a power allocation request to the power management device 50B.

[0078] When the power allocation determination unit 531B of the power management device 50B receives a power allocation request related to the electric vehicle E0, it determines that the number of currently charged electric vehicles, "12 vehicles", stored in the in-use power amount storage unit 512B has reached the number of electric vehicles that can be charged simultaneously, "12 vehicles", stored in the available power amount storage unit 511B, and power cannot be allocated to the electric vehicle E0 (in step S11, "yes").

[0079] When the power distribution determination unit 531B determines that power distribution to the electric vehicle E0 cannot be performed, it generates power distribution waiting information related to the electric vehicle E0 and stores it in the distribution waiting information storage unit 513B, and generates a non-permission power distribution notice as a distribution determination result notice related to the electric vehicle E0, and sends it to the corresponding first parking lot management device 100B (step S7).

[0080] In the first parking lot management device 100B, the charger control unit 134 acquires the power non-distribution permission notice sent from the power management device 50B (in step S8, "no"). When the charger control unit 134 acquires the non-permission power distribution notice, it keeps the power supply device of the charger 13 installed on the shelf 11 where the electric vehicle E0 is stored in the off state.

[0081] After that, with reference to Figure 6 the sequence diagram, the power management process executed by the parking lot management system 1B will be described.

[0082] In the first parking lot 10 to the fourth parking lot 40, each electric vehicle to be charged is charged for a preset time (for example, 2 hours). When this time elapses, the charger control unit switches the power supply device of the corresponding charger to the off state. For example, if the charging time for the electric vehicle E10 elapses in the third parking lot 30, the charger control unit 334 switches the corresponding power supply device to the off state (in step S11, "yes").

[0083] When the charger control unit 334 switches the power supply device to the off state, it generates a charging completion notice related to the electric vehicle E10 and sends it to the power management device 50B (step S12). In the power management device 50B, the power distribution determination unit 531B acquires the charging completion notice related to the electric vehicle E10 sent from the third parking lot management device 300B, and updates the power consumption information stored in the in-use power amount storage unit 512B by reducing the number of currently charging electric vehicles by 1 (step S13).

[0084] When the power distribution determination unit 531B determines that since the number of currently charging electric vehicles has decreased, the currently used power amount has decreased, and power distribution to the electric vehicle corresponding to the power distribution waiting information stored in the distribution waiting information storage unit 513B can be performed (in step S14, "yes"), it sends the determination result to the determination result notification unit 532B, and deletes the power distribution waiting information stored in the distribution waiting information storage unit 513B (step S15).

[0085] Based on the determination result of the power distribution determination unit 531B, the determination result notification unit 532B generates a power distribution permission notification related to the electric vehicle E13 with the highest priority among the power vehicles in the power waiting state, and sends it to the corresponding first parking lot management device 100B (step S16).

[0086] In the first parking lot management device 100B, when obtaining the power distribution permission notification related to the electric vehicle E13 sent from the power management device 50B, the charger control unit 134 switches the power supply device opposite to the charger 13 provided on the shelf 11 where the electric vehicle E13 is stored to the on state (step S17).

[0087] In step S14 above, when the power distribution determination unit 531B determines that power distribution to the electric vehicle corresponding to the power distribution waiting information stored in the power distribution waiting information storage unit 513B cannot be performed (in step S14, "no"), the process ends.

[0088] According to the above second embodiment, when the power amount close to the contract power amount is used in multiple parking lots and charging processing cannot be performed on the newly stored electric vehicle, by performing the charging waiting process, the charging process can be started at the time point when the charging process can be performed on the electric vehicle.

[0089] 《Third Embodiment》

[0090] 〈Structure of Parking Lot Management System〉

[0091] Figure 7 It is an overall view showing the structure of the parking lot management system 1C according to the third embodiment of the present invention. The parking lot management system 1C of the third embodiment has the same structure as the parking lot management system 1B described in the second embodiment except that it has the first parking lot management device 100C, the second parking lot management device 200C, the third parking lot management device 300C, the fourth parking lot management device 400C, and the power management device 50C instead of the first parking lot management device 100B, the second parking lot management device 200B, the third parking lot management device 300B, the fourth parking lot management device 400B, and the power management device 50B. Therefore, the detailed description of the parts with the same functions is omitted.

[0092] The available power amount storage unit 511C of the power management device 50C stores the available power amount information of at least any one of each parking lot group and each parking lot classified for multiple parking lots. The in-use power amount storage unit 512C stores the in-use power amount of at least any one of each parking lot group and each parking lot. The distribution waiting information storage unit 513C stores the power distribution waiting information for each parking lot.

[0093] When the power distribution determination unit 531C receives a power distribution request from a certain parking lot management device, it determines whether power can be distributed to the received request based on the available power amount information and the in-use power amount information of the corresponding parking lot group or parking lot. In addition, when the power distribution determination unit 531C detects that charging of a certain electric vehicle has been completed in a certain parking lot, it determines whether power distribution to the electric vehicle corresponding to the power distribution waiting information can be performed based on the available power amount information, the in-use power amount information, and the power distribution waiting information of the corresponding parking lot group or parking lot.

[0094] 〈Operation of Parking Lot Management System〉

[0095] As an example of the operation of the parking lot management system 1C of the present embodiment, the processing performed when the electric vehicle E0 enters the first parking lot 10 will be described.

[0096] In the present embodiment, the power management device 50C manages the first parking lot 10 and the second parking lot 20 among the first parking lot 10 to the fourth parking lot 40 to be managed as the parking lots of the first parking lot group G1, and manages the third parking lot 30 and the fourth parking lot 40 as the parking lots of the second parking lot group G2.

[0097] In the present embodiment, in the available power amount storage unit 511C of the power management device 50C, as the available power amount information related to the first parking lot group G1, the number of electric vehicles that can be charged simultaneously, "6 vehicles", is stored. As the available power amount information related to the second parking lot group G2, the number of electric vehicles that can be charged simultaneously, "4 vehicles", is stored. In addition, in the available power amount storage unit 511C, different from the available power amount information of the first parking lot group G1 and the second parking lot group G2, as the available power amount information unique to the first parking lot 10, the number of electric vehicles that can be charged simultaneously, "2 vehicles", is also stored. The available power amount information unique to the first parking lot 10 is information on the available power amount allocated to a predetermined user by signing a contract that allows charging at all times, and is not included in the available power amount information related to the first parking lot group G1.

[0098] In addition, before the electric vehicle E0 enters the warehouse, as Figure 7 shown, there are 6 electric vehicles E1 to E6 parked in the first parking lot 10 and being charged. Among the electric vehicles E1 to E6, the 2 electric vehicles E1 and E2 are charged using the available power amount inherently allocated to the first parking lot 10, and the 4 electric vehicles E3 to E6 are charged using the available power amount allocated to the first parking lot group G1.

[0099] In the second parking lot 20, two electric vehicles E7 and E8 are being charged, and one ordinary vehicle C1 that is not an electric vehicle is stored. The electric vehicles E7 and E8 are charged using the available power amount allocated to the first parking lot group G1.

[0100] In the third parking lot 30, two electric vehicles E9 and E10 are being charged, and three ordinary vehicles C2, C3, and C4 are stored. The electric vehicles E9 and E10 are charged using the available power amount allocated to the second parking lot group G2. In the fourth parking lot 40, two ordinary vehicles C5 and C6 are stored.

[0101] According to such a storage situation, in the in-use power amount storage unit 512C, as the in-use power amount related to the first parking lot group G1, the number of electric vehicles "6" charged using the available power amount allocated to the first parking lot group G1 is stored. In addition, in the in-use power amount storage unit 512C, as the in-use power amount related to the second parking lot group G2, the number of electric vehicles "2" charged using the available power amount allocated to the second parking lot group G2 is stored. In addition, in the in-use power amount storage unit 512C, the number of electric vehicles "2" charged using the available power amount inherently allocated to the first parking lot 10 is stored.

[0102] As described above, various information is stored in the power management device 50C. When the user of the electric vehicle E0 requests the electric vehicle E0 to enter the first parking lot 10 through the operation panel 15 in the state where vehicles are stored in each parking lot, the corresponding first parking lot management device 100C performs the same processing as steps S1 to S5 described in the first embodiment, and sends a power allocation request to the power management device 50C.

[0103] When the power allocation determination unit 531C of the power management device 50C receives a power allocation request related to the electric vehicle E0 in the first parking lot 10, it determines whether power can be allocated to the received request based on the available power amount information of the first parking lot group G1 corresponding to the first parking lot 10, the available power amount information inherent to the first parking lot 10, the in-use power amount information of the first parking lot group G1, and the in-use power amount information inherent to the first parking lot 10 (step S6).

[0104] Here, the power distribution determination unit 531C recognizes that the number of electric vehicles being currently charged, i.e., "6 vehicles", which is the power consumption information related to the first parking lot group G1 stored in the in-use power storage unit 512C, has reached the number of electric vehicles that can be charged simultaneously, i.e., "6 vehicles", which is the available power information related to the first parking lot group G1 stored in the available power storage unit 511C. In addition, the power distribution determination unit 531C recognizes that the number of electric vehicles being currently charged, i.e., "2 vehicles", relative to the available power inherent to the first parking lot 10, has reached the number of electric vehicles that can be charged simultaneously, i.e., "2 vehicles", relative to the available power inherent to the first parking lot 10. Based on the recognized information, even if there is still a surplus in the overall power consumption of the first parking lot 10 to the fourth parking lot 40, the power distribution determination unit 531C determines that power distribution to the electric vehicle E0 in the first parking lot 10 cannot be performed.

[0105] When the power distribution determination unit 531C determines that power distribution to the electric vehicle E0 cannot be performed, it generates power distribution waiting information related to the electric vehicle E0 and stores it in the distribution waiting information storage unit 513C, and generates a non-permission power distribution notice as a distribution determination result notice related to the electric vehicle E0, and sends it to the corresponding first parking lot management device 100C (step S7).

[0106] In the first parking lot management device 100C, the charger control unit 134 acquires the non-permission power distribution notice sent from the power management device 50C ("Yes" in step S8). When the charger control unit 134 acquires the non-permission power distribution notice, it keeps the power supply device of the charger 13 installed in the shelf 11 where the electric vehicle E0 is parked in the off state.

[0107] After that, during the process of the electric vehicle E0 parking in the first parking lot 10, if the charging process of a certain electric vehicle is completed within the first parking lot 10 to the fourth parking lot 40, the corresponding charger control unit switches the power supply device of the corresponding charger to the off state ("Yes" in step S11), generates a charging completion notice related to the electric vehicle and sends it to the power management device 50C (step S12).

[0108] When the power distribution determination unit 531C receives a charging completion notification from the corresponding parking lot management device, it updates the number of electric vehicles currently being charged in the corresponding parking lot stored in the in-use power amount storage unit 512C by reducing it by 1 (S13). For example, if the charging process for the electric vehicle E1 is completed in the first parking lot 10 and a charging completion notification related to the electric vehicle E1 is sent from the parking lot management device 100C to the power management device 50C, the power distribution determination unit 531C reduces the number of electric vehicles currently being charged, which is specific to the first parking lot 10 and stored in the in-use power amount storage unit 512C, to "1 vehicle".

[0109] If the power distribution determination unit 531C determines that the current power consumption has decreased due to the reduction in the number of electric vehicles currently being charged in the first parking lot 10 and power distribution to the electric vehicle corresponding to the power distribution waiting information related to the first parking lot 10 stored in the distribution waiting information storage unit 513C can be performed ("Yes" in step S14), it sends the determination result to the determination result notification unit 532C and deletes the power waiting information related to the electric vehicle E0, which is one piece of power distribution waiting information corresponding to the first parking lot 10, stored in the distribution waiting information storage unit 513C (S15).

[0110] Based on the determination result of the power distribution determination unit 531C, the determination result notification unit 532C generates a power distribution permission notification related to the electric vehicle E0 and sends it to the corresponding first parking lot management device 100C (S16).

[0111] In the first parking lot management device 100C, when it receives the power distribution permission notification related to the electric vehicle E0 sent from the power management device 50C, the charger control unit 134 switches the power supply device opposite to the charger 13 provided on the shelf 11 where the electric vehicle E0 is placed to the on state (step S17).

[0112] In the above-described embodiment, when the contract for always being able to charge and use in the first parking lot 10 is terminated, the number of electric vehicles that can be charged simultaneously, which is stored as the available power amount information specific to the first parking lot 10, is changed from "2 vehicles" to "1 vehicle".

[0113] According to the above third embodiment, by presetting the power distribution for each group and each parking lot after classifying multiple parking lots, power management corresponding to the usage mode can be performed. For example, among multiple parking lots provided in a commercial facility, it is also possible to group them into a parking lot for staff use and a parking lot for visitors, and make the number of allocated power different. In addition, at this time, it is also possible to make the available power amount different for each group or each parking lot according to each time period or each week, etc.

[0114] 《Fourth Embodiment》

[0115] 〈Structure of Parking Lot Management System〉

[0116] Figure 8 It is an overall view showing the structure of the parking lot management system 1D of the fourth embodiment of the present invention. The parking lot management system 1D of the fourth embodiment has a first parking lot management device 100D, a second parking lot management device 200D, a third parking lot management device 300D, a fourth parking lot management device 400D, and a power management device 50D instead of the first parking lot management device 100A, the second parking lot management device 200A, the third parking lot management device 300A, the fourth parking lot management device 400A, and the power management device 50A, and also has an entrance management device 60. In addition, it has the same structure as the parking lot management system 1A described in the first embodiment, so the detailed description of the parts with the same functions is omitted.

[0117] Figure 9 It is a block diagram showing the detailed structures of the first parking lot management device 100D to the fourth parking lot management device 400D, the power management device 50D, and the entrance management device 60.

[0118] The first parking lot management device 100D has a first communication unit 120 and a first CPU 130D. The first CPU 130D has an operation control unit 132 and a charger control unit 134.

[0119] The power management device 50D has a second storage unit 51D and a second CPU 53D. The second storage unit 51D includes an available power amount storage unit 511D and a power amount in use storage unit 512D. The available power amount storage unit 511D stores the number of electric vehicles that can be charged simultaneously in the first parking lot 10 to the fourth parking lot 40 as the available power amount information for the first parking lot 10 to the fourth parking lot 40 as a whole. In addition, the available power amount storage unit 511D stores the number of electric vehicles that can be charged simultaneously in each parking lot as the available power amount information for each of the first parking lot 10 to the fourth parking lot 40.

[0120] The power consumption storage unit 512D stores the number of electric vehicles currently being charged among all of the first to fourth parking lots 10 to 40 as the power consumption information of all of the first to fourth parking lots 10 to 40. In addition, the power consumption storage unit 512D stores the number of electric vehicles currently being charged in each parking lot as the power consumption information of each of the first to fourth parking lots 10 to 40.

[0121] When the power distribution determination unit 531D receives the rechargeable device determination request described below from the warehousing management device 60, it extracts the parking lot that can distribute power to the electric vehicle requesting warehousing and power distribution based on the available power information stored in the available power storage unit 511D and the power consumption information stored in the power consumption storage unit 512D.

[0122] The determination result notification unit 532D sends the rechargeable device determination result generated by the power distribution determination unit 531D to the warehousing management device 60.

[0123] The warehousing management device 60 includes a third storage unit 61, an input unit 62, an output unit 63, a third communication unit 64, and a third CPU 65. The third storage unit 61 includes a second shelf information storage unit 611 as a second storage space information storage unit, which stores shelf information indicating the current presence or absence of vehicles in the storage space for each shelf 11.

[0124] The input unit 62 inputs the operation information of the user. The output unit 63 outputs the information obtained from the third CPU 65 through sound or display information. The input unit 62 and the output unit 63 may be integrally formed by a touch panel. The third communication unit 64 performs communication between the first to fourth parking lot management devices 100D to 400D and the power management device 50D.

[0125] The third CPU 65 includes a second in-out processing unit 651, a second power distribution request unit 652, and a display control unit 653. When the second in-out processing unit 651 detects that a vehicle has requested warehousing and charging in a certain parking lot, it generates a rechargeable device determination request for obtaining information on a rechargeable parking lot and sends it to the power management device 50D. In addition, the second in-out processing unit 651 obtains the rechargeable device determination result sent from the power management device 50D in response to the sent rechargeable device determination request, and determines the parking lot of the warehousing destination of the vehicle based on the obtained rechargeable device determination result and the information stored in the second shelf information storage unit 611.

[0126] The display control unit 653 causes the output unit 63 to output the information on the parking lot of the warehousing destination determined by the second in-out processing unit 651 and the information related to power distribution obtained from the power management device 50D.

[0127] <Actions of the parking lot management system>

[0128] As an example of the operation of the parking lot management system 1D of the present embodiment, the processing executed when the electric vehicle E0 enters any one of the first parking lot 10 to the fourth parking lot 40 will be described.

[0129] In the present embodiment, in the available power amount storage unit 511D of the power management device 50D, as the available power amount information of the entire first parking lot 10 to the fourth parking lot 40, the number of electric vehicles "12 vehicles" that can be charged simultaneously in the entire first parking lot 10 to the fourth parking lot 40 is stored. In addition, in the available power amount storage unit 511D, as the available power amount information of each of the first parking lot 10 to the fourth parking lot 40, the number of electric vehicles "6 vehicles" that can be charged simultaneously in each parking lot is stored.

[0130] In addition, before the electric vehicle E0 enters the warehouse, as Figure 8 shown, 6 electric vehicles E1 to E6 are stored in the first parking lot 10 and are being charged. 2 electric vehicles E7 and E8 are stored in the second parking lot 20 and are being charged, and 1 non-electric vehicle ordinary vehicle C1 is stored. 2 electric vehicles E9 and E10 are stored in the third parking lot 30 and are being charged, and 3 ordinary vehicles C2, C3, and C4 are stored. 2 ordinary vehicles C5 and C6 are stored in the fourth parking lot 40. That is, a total of 10 electric vehicles are being charged in the first parking lot 10 to the fourth parking lot 40. In the in-use power amount storage unit 512D, as the in-use power amount information, the number of currently charging electric vehicles in the entire first parking lot 10 to the fourth parking lot 40 "10 vehicles", the number of currently charging electric vehicles in the first parking lot 10 "6 vehicles", the number of currently charging electric vehicles in the second parking lot 20 "2 vehicles", the number of currently charging electric vehicles in the third parking lot 30 "2 vehicles", and the number of currently charging electric vehicles in the fourth parking lot 40 "0 vehicles" are stored.

[0131] Figure 10 It is a sequence diagram showing the operation of the parking lot management system 1D of the present embodiment. First, if the user of the electric vehicle E0 performs an operation of requesting the entry of the electric vehicle E0 from the input unit 62 of the entry management device 60, the second entry / exit processing unit 651 acquires the corresponding operation and detects that an entry request vehicle has occurred for a certain parking lot among the first parking lot 10 to the fourth parking lot 40 ("Yes" in step S21).

[0132] If the second in-out processing unit 651 detects an incoming vehicle for which an incoming request has been made, it determines whether the electric vehicle E0 can enter a certain parking lot among the first parking lot 10 to the fourth parking lot 40 based on the shelf information stored in the second shelf information storage unit 611 (step S22).

[0133] Based on the shelf information, the second in-out processing unit 651 identifies a shelf in an idle state in the first parking lot 10 to the fourth parking lot 40 and determines that the electric vehicle E0 can enter ( "Yes" in step S22). If the second in-out processing unit 651 determines that the electric vehicle E0 can enter, since the vehicle is an electric vehicle, it is identified as a vehicle requesting charging ( "Yes" in step S23), and a rechargeable device determination request for obtaining information on a parking lot where the electric vehicle E0 can be charged is generated and sent to the power management device 50D (step S24).

[0134] In the power management device 50D, the power distribution determination unit 531D obtains the rechargeable device determination request sent from the in-out management device 60, and based on the available power amount information stored in the available power amount storage unit 511D and the in-use power amount information stored in the in-use power amount storage unit 512D, extracts the parking lots that can perform charging processing on the electric vehicle E0. Here, the power distribution determination unit 531D extracts the second parking lot 20, the third parking lot 30, and the fourth parking lot 40 where the number of charging vehicles has not reached 6 as the parking lots that can perform charging processing, and generates a rechargeable device determination result including the identification information of these parking lots. The determination result notification unit 532D sends the rechargeable device determination result generated by the power distribution determination unit 531D to the in-out management device 60 (step S25).

[0135] In the in-out management device 60, the second in-out processing unit 651 obtains the rechargeable device determination result sent from the power management device 50D, and based on the obtained rechargeable device determination result and the information stored in the second shelf information storage unit 611, determines the parking lot for the entry destination of the electric vehicle E0 from the information of the second parking lot 20, the third parking lot 30, and the fourth parking lot 40. Here, the second in-out processing unit 651 determines the second parking lot 20, which is included in the rechargeable device determination result and has a shelf in an idle state, as the entry destination of the electric vehicle E0.

[0136] If the second in-out processing unit 651 determines the entry destination of the electric vehicle E0 as the second parking lot 20, it generates an entry notification notifying the entry of the electric vehicle E0 and sends it to the second parking lot management device 200D (step S26).

[0137] In the second parking lot management device 200D, the operation control unit 232 acquires the warehousing notice sent from the warehousing management device 60, controls the drive device 26 to move the pallet 22 on which the electric vehicle E0 is to be loaded to the loading / unloading port 24, and opens the door of the loading / unloading port 24.

[0138] The user moves the electric vehicle E0 onto the pallet 22 in the second parking lot 20 and gets off, and connects the charger 23 and the electric vehicle E0 through a cable for charging during parking. And if the user operates the operation panel 25 to indicate closing the door, the operation control unit 232 closes the door of the loading / unloading port 24.

[0139] The operation control unit 232 moves the pallet 22 loaded with the electric vehicle E0 from the loading / unloading port 24 to the shelf 21 at the storage destination (step S27). When the pallet 22 reaches the predetermined shelf 21, the charger 23 is installed on the power supply device (not shown) in the second parking lot 20.

[0140] In addition, since the vehicle identified as warehousing in step S23 is an electric vehicle, in step S26, the second loading / unloading processing unit 651 determines the parking lot capable of charging as the warehousing destination. Thus, the second power distribution request unit 652 determines that charging processing is to be performed on the warehousing electric vehicle E0 ( "Yes" in step S28). The second power distribution request unit 652 generates a power distribution request for the electric vehicle E0 to the second parking lot 20 determined as the warehousing destination of the electric vehicle E0, and sends it to the power management device 50D.

[0141] In the power management device 50D, the power distribution determination unit 531D acquires the power distribution request sent from the warehousing management device 60, updates the information in the in-use power amount storage unit 512D based on the acquired request, and generates a power distribution notice for the electric vehicle E0 to the second parking lot 20. The determination result notification unit 532D sends the generated power distribution notice to the corresponding second parking lot management device 200D (step S30).

[0142] In the second parking lot management device 200D, the charger control unit 234 acquires the power distribution notice sent from the power management device 50D ( "Yes" in step S31). If the charger control unit 234 acquires the power distribution notice, it switches the charger 23 provided on the shelf 21 where the electric vehicle E0 is stored to the power supply available state. Specifically, the charger control unit 234 switches the power supply device on which the corresponding charger 23 is installed to the on state (step S32).

[0143] Further, if the second in-out processing unit 651 determines that the electric vehicle E0 cannot be stored in any of the parking lots (No in step S22), the storage process is not executed, and the process returns to step S21.

[0144] In addition, when the second in-out processing unit 651 determines that the vehicle requesting storage is not an electric vehicle (No in step S23), the process does not transfer to step S25 but transfers to step S26, and the parking lot for the storage destination of the electric vehicle E0 is determined based on the information stored in the second shelf information storage unit 611.

[0145] In addition, when the vehicle being stored is not subjected to a charging process, specifically, when it is identified in step S23 that the vehicle being stored is not an electric vehicle, when in step S26 the second in-out processing unit 651 determines that there is no parking lot capable of charging as the storage destination of the electric vehicle E0, or when a non-chargeable parking lot is determined as the storage destination, the process ends without performing a charging process (No in step S28).

[0146] According to the above fourth embodiment, regarding multiple parking lots provided with charging devices, when the in-out management device uniformly determines the feasibility of storing an electric vehicle, it is possible to consider the charging process status in multiple parking lots and determine the parking lot capable of performing a charging process as the storage destination.

[0147] In the above fourth embodiment, it is described that the power management device 50D sends the information of multiple parking lots extracted according to the obtained rechargeable device determination request to the in-out management device as the rechargeable device determination result. However, the power management device 50D may also determine the best one parking lot according to the rechargeable device determination request and send it to the in-out management device 60 as the rechargeable device determination result. With such a configuration, the processing load of the in-out management device 60 can be reduced.

[0148] The power management device 50D and the in-out management device 60 described in the above fourth embodiment may also be configured as an integrated device.

[0149] In the above first to fourth embodiments, the case where the parking lot that is the management object of the parking lot management systems 1A to 1D is a mechanical parking lot has been described, but it is not limited thereto, and it may also be a self-propelled parking lot or a flat parking lot.

[0150] In addition, in the above-described first to fourth embodiments, the case where the storage management system is a parking lot management system, the storage to be managed is a parking lot, and the stored item is a vehicle has been described, but it is not limited thereto. The stored item in the parking lot may also be a scooter or a bicycle. In addition, the storage may be a parking device for drones or robots, and the stored item may be a drone or a robot equipped with a battery. The charger may be a device that supplies power to the stored drone or robot. The storage management device may also be a management device that manages them. Furthermore, as the item stored in the storage and the object to be powered, as long as it is an item that can be stored in the storage and is equipped with a battery, for example, it may also be an electronic device such as a portable power supply device, or a container, storage box, etc. that is equipped with a battery and uses the power supplied by the battery for refrigeration or ventilation.

[0151] Above, the embodiments of the present invention have been described, but modifications or variations of the embodiments can be made based on the above disclosure. As long as all the constituent elements of the above embodiments and all the features described in the scope of patent protection do not contradict each other, they can also be separately extracted and combined.
