Description

Technical Field

[0001] The present invention relates to an elevator - electric vehicle charging and discharging control system and an elevator - electric vehicle charging and discharging control method.

Background Art

[0002] In recent years, electric vehicles powered by batteries have been popularized and expanded. Along with this, the installation of charging facilities for electric vehicles in large facilities such as shopping centers, condominiums, and office buildings has also been popularized and expanded. This charging facility usually charges electric vehicles, but it can also switch from charging to power supply during a power outage in a building and supply power to the facilities in the building using the battery of the electric vehicle. And devices and products as so - called hybrid - type electric vehicle charging facilities have also been developed.

[0003]

[0004] On the other hand, buildings such as condominiums usually have elevators as lifting facilities. To prevent passengers from being trapped in the elevator during a power outage, facilities for running to the nearest floor using the battery equipped in the elevator are often provided. However, the battery equipped in the elevator is basically for the purpose of preventing trapping, and since its power - supplying capacity is small, there is a problem that the elevator stops until the power outage is restored after running to the nearest floor.

[0005] Therefore, an elevator system has been proposed in which, when a power outage occurs and the supply of commercial power to the elevator system is cut off, a switching unit on a power supply stand installed in the building switches to the side that supplies power to the elevator system, and the elevator is powered from the power supply of an electric vehicle, thereby allowing the elevator to operate even during a power outage (see Patent Document 2). [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2021-180548 [Patent Document 2] Japanese Patent Publication No. 2015-51844 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] As described in Patent Document 2, it is possible to operate an elevator during a power outage by supplying power from an electric vehicle to the elevator using an electric vehicle charging facility installed in the building. However, while the elevator system described in Patent Document 2 mentions supplying power from an electric vehicle to the elevator using electric vehicle charging equipment during a power outage, it does not mention supplying power from an electric vehicle that was being charged during a power outage to building equipment such as the elevator.

[0008] Generally, when a power outage occurs and electricity needs to be supplied to building facilities such as elevators from electric vehicle charging stations, the power is supplied by electric vehicles belonging to the building manager or building facilities maintenance company. However, if a power outage occurs while an electric vehicle owned by a regular user is charging, it becomes impossible to connect the electric vehicles of building managers or building equipment maintenance companies. Therefore, building managers and building equipment maintenance companies need to ask users of electric vehicles currently charging to move their vehicles, but if they cannot contact the users of the charging electric vehicles, they cannot smoothly restore building equipment such as elevators.

[0009] The object of the present invention is to provide an elevator-electric vehicle charging and power supply control system and an elevator-electric vehicle charging and power supply control method that enable smooth temporary restoration of elevators by contacting users of electric vehicles being charged, even if a power outage occurs in a building while an electric vehicle is being charged using charging equipment installed in the building. [Means for solving the problem]

[0010] To solve the above problems, for example, the configuration described in the claims may be adopted. This invention includes multiple means for solving the above problems, but to give one example, the present invention is an elevator / electric vehicle charging and power supply control system that is connected to an electric vehicle and an elevator, and is equipped with a hybrid electric vehicle charging facility that is capable of charging and supplying power to the electric vehicle and supplying power to the elevator, and in the event of a power outage, power can be supplied from the electric vehicle to the elevator via the hybrid electric vehicle charging facility, Hybrid electric vehicle charging facilities are used by elevator and building management companies in the event of a power outage. Building equipment monitoring center The system includes a dedicated app / building equipment monitoring center linkage unit that receives power outage detection information and notifies the user's smartphone of the user who owns an electric vehicle that is charging, asking for confirmation as to whether or not it is permissible to supply power from the user's electric vehicle that is charging to the elevator, and a charging and supply control unit that controls the start and stop of power supply from the electric vehicle to the elevator. The dedicated app and building equipment monitoring center coordination unit will notify the user's smartphone via the dedicated app if permission to supply power to the elevator from the user's charging electric vehicle is not granted, requesting a change in the electric vehicle's parking location. Furthermore, when the user's smartphone app notifies the building management company that the electric vehicle's parking location has been changed, the unit will notify the elevator and building management company's building equipment monitoring center of the change in the electric vehicle's parking location. The building's equipment monitoring center then moves another electric vehicle, prepared for power supply, to the empty space left after the first electric vehicle has moved, and supplies power to the elevator. . [Effects of the Invention]

[0011] According to the present invention, in the event of a power outage, the power supply of an electric vehicle that is being charged can be used to supply power to the elevator, or if it is not possible to supply power to the elevator from an electric vehicle that is being charged, the power supply of another electric vehicle prepared for power supply can be used to supply power to the elevator, thereby enabling a smooth temporary restoration of the elevator. Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

Modes for Carrying Out the Invention

[0013] <Overall Configuration of Elevator - Electric Vehicle Charging and Discharging Control System> Hereinafter, embodiments of the elevator - electric vehicle charging and discharging control system of the present invention (hereinafter referred to as "this example") will be described in detail with reference to FIGS. 1 to 7. FIG. 1 is a functional block diagram showing the overall configuration of the functions of the elevator - electric vehicle charging and discharging control system of this example. As shown in FIG. 1, in the elevator - electric vehicle charging and discharging control system of this example, commercial power supply 1 is supplied to building facilities such as an elevator via hybrid electric vehicle charging equipment 2.

[0014] [Configuration of Hybrid Electric Vehicle Charging Equipment 2] Hybrid electric vehicle charging equipment 2 is connected to electric vehicle 19. When there is a power outage in commercial power supply 1, power from the battery mounted on electric vehicle 19 is supplied from hybrid electric vehicle charging equipment 2 to elevator 12, and elevator 12 is configured to operate.

[0015] Hybrid electric vehicle charging equipment 2 includes a power switching unit 3, an AC / DC conversion unit 4, a charging unit 5, a power supply unit 6, a charging and discharging switching unit 7, a charging and discharging control unit 8, a battery remaining amount detection unit 9, a dedicated app - building facility monitoring center cooperation unit 10, and a communication unit 11.

[0016] The AC / DC converter 4 of the hybrid electric vehicle charging equipment 2 converts the commercial power supply 1 (AC power supply such as 200V) to a DC power supply (direct current power supply) during normal operation when the commercial power supply 1 is supplied, and supplies the converted DC power supply to the charging unit 5. The charging unit 5 supplies the obtained DC power to the electric vehicle 19 via the charging / power supply switching unit 7 to charge the battery mounted on the electric vehicle 19.

[0017] Normally, the remaining battery charge and charging / discharging status of the electric vehicle 19 are managed by a battery control unit (not shown) installed in the electric vehicle 19. The battery charge detection unit 9 communicates with the battery control unit installed in the electric vehicle 19 to manage the charging and discharging status of the electric vehicle 19's battery.

[0018] Furthermore, the charging and power supply control unit 8 controls the switching between charging and power supply in the charging and power supply switching unit 7, as well as the timing of starting and ending charging to the electric vehicle 19 and starting and ending power supply from the electric vehicle 19. In other words, the charging and power supply control unit 8 controls the timing of starting charging or power supply to the electric vehicle 19 based on information from a dedicated app 20 on the user's smartphone 21, which is obtained from the dedicated app / building equipment monitoring center linkage unit 10.

[0019] Furthermore, the charging and supply control unit 8 also controls the cessation of charging to the electric vehicle 19 when the battery level detection unit 9 detects that the battery is fully charged. The charging and supply control unit 8 then notifies the dedicated app 20 on the user's smartphone 21 and the building equipment monitoring center 23 of the elevator and building management company 22, via the dedicated app / building equipment monitoring center linkage unit 10, that the battery is fully charged and charging of the electric vehicle 19 has been completed. Furthermore, the dedicated app / building equipment monitoring center linkage unit 10 receives battery level information from the battery level detection unit 9 and notifies the dedicated app 20 on the user's smartphone 21 and the building equipment monitoring center 23 of the battery level via the communication unit 11.

[0020] The dedicated app 20 on the user's smartphone 21 holds the user identification information of the electric vehicle 19, and the dedicated app / building equipment monitoring center linkage unit 10 holds the identification information of the hybrid electric vehicle charging equipment 2. This identification information is recorded in a storage device (database) not shown, provided by the building equipment monitoring center 23 of the elevator / building management company 22. Then, when a command to start charging the electric vehicle 19 is received via the dedicated app 20 on the user's smartphone 21, this charging start information is transmitted from the dedicated app 20 on the user's smartphone 21 to the building equipment monitoring center 23.

[0021] Furthermore, the power switching unit 3 of the hybrid electric vehicle charging equipment 2 performs switching processing of the power supplied to the elevator 12 based on a command from the charging and power supply control unit 8. That is, under normal circumstances when the commercial power supply 1 is used by the elevator 12, the power switching unit 3 supplies the commercial power supply 1 to the power input unit 14 of the elevator 12. In the event of a power outage of the commercial power supply 1, the power switching unit 3 supplies power supplied from the electric vehicle 19 to the power input unit 14 of the elevator 12 based on a command from the charging and power supply control unit 8.

[0022] The charging and power supply control unit 8 switches the charging and power supply switching unit 7 to power supply mode when power is supplied from the electric vehicle 19 during a power outage. The charging and power supply control unit 8 then supplies power from the electric vehicle 19 to the AC / DC conversion unit 4 via the power supply unit 6. The AC / DC conversion unit 4 then converts the DC power from the electric vehicle 19 to AC power and supplies it to the power input unit 14 of the elevator 12 via the power switching unit 3.

[0023] [Elevator 12 configuration] The elevator 12 includes a power outage detection unit 13, a power input unit 14, an elevator control unit 15, an emergency battery 16, an elevator monitoring device 17, and a communication unit 18. The power outage detection unit 13 detects a power outage in the commercial power supply 1 and transmits power outage detection information to the elevator control unit 15.

[0024] The power input unit 14 receives power from the power switching unit 3 of the hybrid electric vehicle charging equipment 2, or from the commercial power supply 1 or the electric vehicle 19. In other words, the power input unit 14 of the elevator 12 performs power input processing to operate the elevator 12 using the power supplied from the power switching unit 3 of the hybrid electric vehicle charging equipment 2. The elevator control unit 15 operates using power supplied to the power input unit 14 and controls the operation of the elevator 12, including the movement and stopping of the elevator car by a hoisting machine (not shown), and the opening and closing of the elevator car doors.

[0025] Although not shown in the diagram, the elevator car is equipped with automatic announcement functions such as guide lights and LCD indicators to provide guidance and status information to users of elevator 12. The emergency battery 16 is designed to allow the elevator car to travel to the nearest floor, open and close the doors, and then stop in the event of a power outage that cuts off the power supply to the elevator 12. However, the capacity of this emergency battery 16 is only sufficient to allow the elevator car to travel to the nearest floor, open and close the doors, and then stop at least once. Therefore, if the emergency battery 16 runs out of charge, it will take some time after the commercial power supply 1 is restored for the emergency battery 16 to fully charge.

[0026] The elevator monitoring device 17 is a device that monitors for abnormalities in the elevator 12. When the elevator monitoring device 17 detects an abnormality in the elevator 12, it notifies the elevator monitoring center 24 of the elevator and building management company 22 via the communication unit 18.

[0027] The building equipment monitoring center 23 of the elevator and building management company 22 is in cooperation with the elevator monitoring center 24 and receives power outage detection information when a power outage occurs in the elevator 12. The building equipment monitoring center 23 then sends a notification to the user's smartphone 21 asking whether it is OK to supply power to the elevator 12 from the electric vehicle 19 that is charging.

[0028] Furthermore, the building equipment monitoring center 23 is equipped with a storage device (database) (not shown), which records various information regarding the charging of the electric vehicle 19 and the power supply from the electric vehicle 19. This information is transmitted to the building equipment monitoring center 23 from the dedicated app / building equipment monitoring center linkage unit 10 of the hybrid electric vehicle charging equipment 2 and from the dedicated app 20 on the user's smartphone 21. Furthermore, this information will be effectively utilized in the elevator and electric vehicle charging and supply control system during a power outage, as described later in the embodiment shown in Figure 7.

[0029] [Image of user's smartphone 21] Figure 2 is an illustrative diagram showing how the elevator and building management company 22 contacts a user's smartphone 21 to inquire whether power can be supplied to the elevator 12 from the user of an electric vehicle 19 that is currently charging. In the example shown in Figure 2, the building equipment monitoring center 23 of the elevator and building management company 22 sends an example message to the user's smartphone 21 that reads, "Due to a power outage inside the building, the elevators in the building are currently out of service. We can temporarily use the elevators by supplying power from an electric vehicle that is currently charging. Could you please supply power to the elevators?"

[0030] If the user authorizes the supply of power to elevator 12, the user will click "Yes (Allow power supply)" displayed on the screen of the user's smartphone 21. If the user does not authorize the supply of power, the user will click "No (Do not allow power supply)".

[0031] If a user authorizes the supply of power to the elevator 12, the dedicated app 20 on the user's smartphone 21 notifies the charging and supply control unit 8 of the permission to supply power to the elevator 12 via the dedicated app / building equipment monitoring center linkage unit 10 of the hybrid electric vehicle charging equipment 2. Then, the power switching unit 3 of the hybrid electric vehicle charging equipment 2 switches the connection of the electric vehicle 19 to the power supply side in response to a command from the charging and supply control unit 8, and supplies the power supplied from the electric vehicle 19 to the power input unit 14 of the elevator 12 via the power supply unit 6, AC / DC conversion unit 4 and power switching unit 3.

[0032] Furthermore, if the user does not authorize the supply of power to elevator 12, a response indicating that power supply to elevator 12 is not authorized is sent from the user's smartphone 21 to the elevator monitoring center 24 via the building equipment monitoring center 23 of the elevator and building management company 22.

[0033] If the user does not authorize the supply of power to the elevator 12, the elevator monitoring center 24 of the elevator and building management company 22 will then need to request the dispatch of an electric vehicle owned by the elevator and building management company 22 for power supply and connect the electric vehicle for power supply to the hybrid electric vehicle charging equipment 2. Therefore, the elevator monitoring center 24 will notify the user's smartphone 21 of the electric vehicle 19 that is charging, requesting a change in the parking position of the electric vehicle 19 that is charging.

[0034] Figure 3 shows an example of a request to change the parking location of a car, which is sent from the building equipment monitoring center 23 to the user's smartphone 21. In the example shown in Figure 3, the building equipment monitoring center 23 sends a notification to the user's smartphone 21 stating, "We have requested the dispatch of a vehicle to supply power to the elevator. We apologize for the inconvenience, but we would appreciate your cooperation in changing the parking position of the charging vehicle in order to supply power to the elevator." Upon receiving this notification, the user clicks "Yes (Change Parking Position)" on their smartphone 21 and sends a notification to the elevator / building management company 22's building equipment monitoring center 23 that the parking position of the charging vehicle has been changed.

[0035] <Hardware configuration of elevator and electric vehicle charging / power supply control system> Figure 4 shows the hardware configuration of the hybrid electric vehicle charging equipment 2 that constitutes the elevator / electric vehicle charging and power supply control system in this example. Each function of the hybrid electric vehicle charging station 2 shown in Figure 1 is realized by a program implemented in the computer device shown in Figure 4. In other words, as shown in Figure 4, the computer device constituting the hybrid electric vehicle charging facility 2 consists of a CPU (Central Processing Unit) 41, ROM (Read Only Memory) 42, RAM (Random Access Memory) 43, non-volatile storage 44, communication interface (communication IF) 45, input unit 46, and output unit 47 connected to the bus 40.

[0036] The CPU 41 reads the program code for the software that implements the functions of the hybrid electric vehicle charging station 2 from the ROM 42 and executes calculations. Variables and other information generated during the calculations performed within the hybrid electric vehicle charging station 2 are temporarily written to the RAM 43.

[0037] The non-volatile storage 44 consists of non-volatile memory such as an SSD (Solid State Drive). This non-volatile storage 44 stores programs and data necessary for the CPU 41 to operate as a hybrid electric vehicle charging station 2.

[0038] For example, a NIC (Network Interface Card) can be used as the communication interface 45. This communication interface 45 corresponds to the communication unit 11 in the hybrid electric vehicle charging equipment 2 shown in Figure 1.

[0039] The input section 46 corresponds to the charging / power supply switching section 7 when power is supplied from the electric vehicle 19 of the hybrid electric vehicle charging equipment 2, and the AC / DC conversion section 4 when power is input from the commercial power supply 1. The output section 47 corresponds to the charging / power supply switching section 7 when charging the electric vehicle 19, and the power switching section 3 that supplies power to the elevator 12.

[0040] While Figure 4 illustrates the hardware configuration of the computer used to implement the functions of the hybrid electric vehicle charging station 2, the elevator 12, user smartphones 21, the building equipment monitoring center of the elevator / building management company 22, and the elevator monitoring center 24 are also composed of computers with software functions to implement their respective functions, similar to the hybrid electric vehicle charging station 2.

[0041] <Charging process for electric vehicle 19> Figure 5 is a flowchart illustrating the charging operation of the electric vehicle 19 in the elevator / electric vehicle charging and supply control system of this example. First, it is determined whether the user has selected to start charging the electric vehicle 19 using the dedicated app 20 on their smartphone 21 (S101). If the user has not selected to start charging the electric vehicle 19 in step S101 (NO in S101), the system waits until the user selects to start charging the electric vehicle 19 using their smartphone 21.

[0042] In step S101, if the user selects to start charging the electric vehicle 19 (YES in S101), the dedicated app 20 on the user's smartphone 21 communicates wirelessly with the dedicated app / building equipment monitoring center linkage unit 10 via the communication unit 11 of the hybrid electric vehicle charging equipment 2.

[0043] Subsequently, the dedicated app 20 transmits the identification information of the hybrid electric vehicle charging equipment 2 received from the dedicated app / building equipment monitoring center linkage unit 10 to the building equipment monitoring center 23 of the elevator / building management company 22 (S102), and then transmits the identification information of the electric vehicle 19 user recorded in the dedicated app 20 (S103). Note that the processing in step S102 and the processing in step S103 may be performed in either order.

[0044] Next, the charging and supply control unit 8 of the hybrid electric vehicle charging equipment 2 receives a charging start command from the dedicated app 20 and starts charging the electric vehicle 19 (S104). The dedicated app / building equipment monitoring center linkage unit 10 receives battery level information from the battery level detection unit 9 and notifies the dedicated app 20 on the user's smartphone 21 and the building equipment monitoring center 23 of the elevator / building management company 22 of the charging status, including the battery level, via the communication unit 11 (S105).

[0045] Next, the battery level detection unit 9 of the hybrid electric vehicle charging equipment 2 detects whether or not the battery of the electric vehicle 19 is fully charged (S106). If the battery level detection unit 9 detects that the battery of the electric vehicle 19 is fully charged in step S106 (YES in S106), the charging and supply control unit 8 stops charging the electric vehicle 19 (S107). If the battery level detection unit 9 does not detect that the battery of the electric vehicle 19 is fully charged (NO in S106), the process returns to S105.

[0046] When charging of the electric vehicle 19 is stopped in step S107, the dedicated app / building equipment monitoring center linkage unit 10 notifies the dedicated app 20 on the user's smartphone 21 and the building equipment monitoring center 23 of the elevator / building management company 22 that charging of the electric vehicle 19 is complete (S108). Although not shown in Figure 5, upon receiving notification of charging completion in step S108, the building equipment monitoring center 23 registers the electric vehicle 19 and its identification code in a storage device (database) not shown. The electric vehicle 19 registered here may also be used to supply power to the elevator 12 during a power outage.

[0047] <Power supply process from electric vehicle 19 to elevator 12> Next, referring to the flowchart in Figure 6, the power supply process from the electric vehicle 19 to the elevator 12 during an elevator power outage in this example of the elevator-electric vehicle charging and power supply control system will be explained. First, the power outage detection unit 13 of the elevator 12 determines whether or not it has detected a power outage in the elevator 12 (S201). If the power outage detection unit 13 has not detected a power outage in the elevator 12 in step S201 (NO in S201), the system returns to step S201 and waits until a power outage is detected.

[0048] In step S201, if the power outage detection unit 13 detects a power outage in the elevator 12 (YES in S201), the elevator monitoring device 17 notifies the elevator monitoring center 24 of the elevator building management company 22 of the power outage detection in the elevator 12 via the communication unit 18 of the elevator 12 (S202).

[0049] Then, the building equipment monitoring center 23 of the elevator and building management company 22 sends a notification to the dedicated app 20 on the user's smartphone 21, which is held by the user of the electric vehicle 19 that is charging, asking for confirmation of whether it is OK to supply power from the user's electric vehicle 19 to the elevator 12 (S203).

[0050] Next, the dedicated app / building equipment monitoring center linkage unit 10 for the hybrid electric vehicle charging equipment 2 determines whether the user of the electric vehicle 19 has authorized the supply of power to the elevator 12 in response to the notification of confirmation of whether power can be supplied to the elevator 12 in step S203 (S204).

[0051] In step S204, if the dedicated app / building equipment monitoring center linkage unit 10 determines that the user of the electric vehicle 19 has authorized the supply of power to the elevator 12 (YES in S204), the dedicated app 20 on the user's smartphone 21 instructs the charging and supply control unit 8 of the hybrid electric vehicle charging equipment 2 to start supplying power to the elevator 12. Then, the power switching unit 3 of the hybrid electric vehicle charging equipment 2 connects the power from the user's electric vehicle 19, which has been authorized to supply power by the command from the charging and supply control unit 8, to the power input unit 14 of the elevator 12 and starts supplying power (S205), and the process ends.

[0052] Furthermore, if, in step S204, the user of the electric vehicle 19 who received a notification confirming whether or not power can be supplied to the elevator 12 refuses to supply power to the elevator 12 (NO in S204), the building equipment monitoring center 23 notifies the user's smartphone 21, which was charging the electric vehicle 19 using the hybrid electric vehicle charging equipment 2, of a message requesting that the parking position (stopping position) of the electric vehicle 19 be changed (see Figure 3) (S206). Then, the building equipment monitoring center 23 determines whether or not a notification has been received from the user's smartphone 21 of the user who received the request to change the parking location of the electric vehicle 19 that the change in parking location has been completed (S207).

[0053] If the user of the electric vehicle 19 replies that the parking location of the electric vehicle 19, which is currently charging, has been changed (YES in S207), the building equipment monitoring center 23 receives the notification of the change in parking location (S208) and terminates the series of processes. Although not shown in Figure 6, once the process in step S207 is completed, the building equipment monitoring center 23 of the elevator and building management company 22 moves an electric vehicle prepared for power supply to the empty space left after the electric vehicle 19 has moved, and supplies power to the elevator 12.

[0054] <Second Embodiment of the Present Invention> Figure 7 is a flowchart showing the processing flow in an elevator / electric vehicle charging and supply control system as a second embodiment of the present invention. The configuration of the second embodiment of the present invention differs from the embodiments described so far in that multiple electric vehicles 19 being charged are connected to the charging / discharging switching unit 7 of the hybrid electric vehicle charging equipment 2 shown in Figure 1. The other configurations of the hybrid electric vehicle charging equipment 2 and elevator 12 are the same as those shown in Figure 1.

[0055] Steps S301 and S302 shown in Figure 7 are the same as steps 201 and S202 in Figure 6, so redundant explanations are omitted. In step S302, when the elevator monitoring device 17 of elevator 12 notifies the elevator monitoring center 24 of the elevator / building management company 22 of the power outage detection information, the building equipment monitoring center 23, via the dedicated app / building equipment monitoring center linkage unit 10 of the hybrid electric vehicle charging equipment 2, inquires whether it is possible to supply power to elevator 12 from all of the electric vehicles 19 that are currently charging (S303). Upon receiving this inquiry, the dedicated app / building equipment monitoring center linkage unit 10 determines whether at least one user of the electric vehicles 19 that are currently charging has authorized the supply of power to elevator 12 (S304).

[0056] In step S304, if power supply from the electric vehicle 19 to the elevator 12 is permitted (YES in S304), that is, if at least one user who owns an electric vehicle 19 that is being charged has permitted power supply to the elevator 12 (S305). Then, the charging and supply control unit 8 of the hybrid electric vehicle charging equipment 2 starts supplying power to the elevator 12 from all electric vehicles 19 that are being charged and have been permitted to supply power to the elevator 12 (S306), and the process ends.

[0057] If power supply to the elevator 12 is not permitted in step S304 (NO in S304), that is, if all users of the multiple electric vehicles 19 that are being charged have not permitted power supply from the electric vehicles 19 to the elevator 12 (S307). At this time, the building equipment monitoring center 23 sends a request to all users who refused power supply to change the parking location (stopping position) of their electric vehicles 19, which were being charged before the power outage, via a dedicated app 20 on their smartphones 21 (S308).

[0058] Then, the system waits for a response indicating whether or not the change in the parking position (stopping position) of the electric vehicle 19 that was charging has been completed (S309). In step S309, if the change in the parking position (stopping position) of any of the electric vehicles 19 that was charging has been completed (YES in S309), the user of any of the electric vehicles 19 that was charging will be notified of the completion of the change in the parking position of the electric vehicle 19 via the dedicated app 20 on their user smartphone 21 (S310). Then, the building equipment monitoring center 23 dispatches an electric vehicle for power supply, connects it to the charge / supply switching unit 7 of the hybrid electric vehicle charging equipment 2, starts supplying power to the elevator 12, and ends the process. If, in step S309, no notification of completion of the parking position change is received from any of the charging vehicles (NO in S309), return to step S308 and wait for a notification of completion of the parking position change.

[0059] [Differentiation] In the processing flow of the second embodiment shown in Figure 7, in step S303, a query is simultaneously sent to the dedicated app 20 on the user smartphones 21 of all users who own an electric vehicle 19 that is charging, asking whether it is possible to supply power from the electric vehicle 19 that is charging to the elevator 12.

[0060] However, among the electric vehicles 19 that are charging, some may be nearly fully charged, while others may have just started charging and have a low charge level. Taking this situation into consideration, the building equipment monitoring center 23 may, in step S304, first inquire with the user smartphone 21 of the user who owns the electric vehicle 19 with the highest charge level among the users of the electric vehicles 19 that were charging before the power outage, whether it is possible to supply power to the elevator 12.

[0061] Then, in step S304, if the user of the electric vehicle 19 with the highest charge level refuses to supply power, the system will ask the user of the electric vehicle 19 with the next highest charge level whether it is possible to supply power to the elevator 12. This processing procedure can be achieved by recording the battery levels of multiple electric vehicles 19 being charged using the hybrid electric vehicle charging equipment 2 in real time in a storage device (database) not shown, which is connected to the building equipment monitoring center 23 of the elevator and building management company 22.

[0062] In large facilities such as shopping centers, apartment buildings, and office buildings, it is expected that a large number of electric vehicles 19 will be connected to the charging / discharging switching unit 7 of the hybrid electric vehicle charging equipment 2. In such cases, it is effective to inquire about the possibility of supplying power to the elevator 12 in order, starting with the electric vehicle 19 with the highest charge level, thereby avoiding unnecessary inquiries to the electric vehicle 19 with a low charge level that has just started charging.

[0063] Furthermore, in the second embodiment shown in Figure 7, all users of the electric vehicle 19 that is being charged and has refused power supply are requested to change the parking position (stopping position) of the electric vehicle 19. However, by asking users to change their parking position in order of the electric vehicle 19 with the highest charge level, it is possible to minimize unnecessary requests to change parking positions.

[0064] It should be noted that the present invention is not limited to the embodiments described above, but includes various applications and modifications. Furthermore, the embodiments described above are explained for the purpose of clearly illustrating the present invention, and the present invention is not necessarily limited to having all the configurations described above, and can be applied to other configurations as appropriate.
