Description

Technical Field

[0001] The present invention relates to a charging system provided in a building having a plurality of exclusive parts and for charging vehicles such as electric vehicles.

Background Art

[0002] The above charging system is provided in an apartment building having a plurality of living rooms, and is known to enable charging of a vehicle by supplying power from the living room side of the apartment building to a plurality of vehicle chargers installed in a parking lot (see, for example, Patent Document 1).

[0003] When supplying power from the living room side to the vehicle charger, simply supplying power makes it impossible to grasp which user of which living room has used which vehicle charger, and the power consumption during charging cannot be known, resulting in problems such as inability to charge according to the power consumption.

[0004] Therefore, the charging system described in Patent Document 1 includes an authentication information input unit, a power switching device, a charging control unit, etc., and grasps the total power consumption of the residents including the usage amount of the vehicle charger.

[0005] The authentication information input unit is for authenticating that the user is a resident of the apartment building. If the user can be authenticated as a resident of the apartment building, the vehicle charger can be used. The power switching device has a power line arranged from the secondary side of a watt-hour meter installed in each living room of the apartment building drawn in, enables power supply from each individual living room to the vehicle charger, and switches the power supply to the vehicle charger. The charging control unit identifies the living room of the user based on the information input to the authentication information input unit, and controls the power switching device to switch to the power line corresponding to the identified living room for the power line connected to the vehicle charger.

[0006] As a result, the power consumption during charging can also be measured by the electricity meter installed in the user's living room, and by billing the resident for the total power consumption including the power consumption during charging, it is possible to charge according to the power consumption during charging.

Summary of the Invention

Problems to be Solved by the Invention

[0008] In the charging system described in Patent Document 1, since the user does not select the vehicle charger to be used and the charging control unit selects the vehicle charger to be used, it is assumed that one vehicle charger is shared and used by multiple residents. Therefore, for example, in a parking lot, it is conceivable to provide a space for parking a vehicle charger and a space for parking a vehicle to be charged by that vehicle charger separately from the residents' parking spaces.

[0009] Regarding which of the multiple vehicle chargers to use, the charging control unit selects and determines one of the unused vehicle chargers in a predetermined order. Therefore, until the charging control unit selects a vehicle charger, the user may not know which vehicle charger will be used. For this reason, for example, it may be necessary to move the vehicle, such as parking the vehicle at a place other than the vehicle charger once, performing authentication by the authentication information input unit, and then moving the vehicle to the selected vehicle charger and parking it again, and improvement is required in terms of usability.

[0010] In addition, in the charging system described in Patent Document 1, since one vehicle charger is shared by a plurality of residents, for example, it becomes impossible to use the vehicle charger during a time period when users of the vehicle charger concentrate, etc., and it is difficult to meet the demand that the vehicle charger can be used at any time when the user wants to use it.

[0011] In view of this situation, the main problem of the present invention is to provide a user-friendly charging system that is provided in a building having a plurality of exclusive parts, improves the usability of users, and can easily charge a vehicle.

Means for Solving the Problems

[0012] A first characteristic configuration of the present invention is a charging system provided in a building having a plurality of exclusive parts and performing charging of a vehicle, A dedicated charging device is installed, and at least one parking space with a charging device where a vehicle can be parked is provided, A plurality of power lines branched from the secondary side of a watt-hour meter corresponding to each of the plurality of exclusive parts and capable of supplying power, A power supply state switching unit is provided that can freely switch the connection state between the plurality of power lines and the charging device and supplies power from the power line in the connection state to the charging device. The power supply state switching unit is configured to be freely switchable to a connection state for a parking space that connects a power line corresponding to the specified exclusive part and a charging device corresponding to the specified parking space with a charging device based on parking space usage information that determines a parking space with a charging device that can be used by a user of the specified exclusive part in a state that specifies the exclusive part and the parking space with a charging device.

[0013] According to this configuration, the power supply state switching unit switches to a connection state for a parking space that connects a power line corresponding to the specified exclusive part and a charging device corresponding to the specified parking space with a charging device based on the parking space usage information, so that power is supplied from the power line of the specified exclusive part to the charging device of the specified parking space with a charging device, and the charging device becomes usable.

[0014] Accordingly, the power consumption during charging can also be measured by the watt-hour meter corresponding to the exclusive area of the user. For example, by billing the user for the total power consumption including the power consumption during charging, charging can be billed according to the power consumption during charging. Incidentally, by separately providing a watt-hour meter on the path of the power line, the power consumption during charging can be grasped. The user of the exclusive area usually grasps the parking space with a charging device that can be used from the parking space use information, etc., and can charge the vehicle using the charging device corresponding to the parking space with a charging device by simply parking the vehicle in the grasped parking space with a charging device, which is user-friendly. Moreover, since the parking space with a charging device can be utilized as a parking space where the user of the exclusive area parks the vehicle, for example, it is not necessary to provide a charging device and a space for parking the vehicle to be charged by the charging device separately from the parking space.

[0015] The users of the exclusive area who can use the parking space with a charging device are limited to specific users, so the use of one charging device is limited to specific users. Therefore, the users of the exclusive area can freely use the charging device corresponding to the parking space with a charging device at any time when they want to use it without considering the usage status of other charging devices, etc., and can charge the vehicle, thus improving the usability. Moreover, when the building manager or the like switches the connection state for the parking space at the power supply state switching unit, the user of the exclusive area can use the parking space with a charging device without performing authentication or the like, so the usability can be improved. Furthermore, not only a configuration for managing the usage status such as whether each of a plurality of charging devices is in use, but also a configuration for selecting one charging device to be used from a plurality of charging devices may not be provided, and the configuration can be simplified and the cost can be reduced.

[0016] The second characteristic configuration of the present invention is that, as the power line, in addition to the power line branched from the secondary side of the watt-hour meter in the exclusive area, a power line for the common area branched from the secondary side of the watt-hour meter in the common area of the building is provided. The power supply state switching unit is configured to be able to switch to a connection state for the shared part that connects the power line for the shared part and the charging device.

[0017] According to this configuration, by switching the power supply state switching unit to the connection state for the shared part, the charging device can be used in a form where power is supplied from the secondary side of the watt-hour meter in the shared part to the power line for the shared part. As a result, for a parking space with a charging device where the user of the available exclusive part is not defined, for example, a building manager or the like can also allow a person other than the user of the exclusive part to use it. In this case, the amount of power used during charging is also measured by the watt-hour meter in the shared part, and the total power consumption including the power consumption during charging can be grasped. Therefore, charging can be performed considering the total power consumption, such as the amount set by the building manager or the like. Incidentally, by separately providing a watt-hour meter on the path of the power line for the shared part, the amount of power used during charging can be grasped, and charging can be performed considering the amount of power used.

[0018] In this way, not only does it become a convenient system where the user of the exclusive part can freely use the charging device, but also a building manager or the like can use a parking space with a charging device where the user of the available exclusive part is not defined for another use purpose, making it a convenient system for the building manager or the like as well.

[0019] The third characteristic configuration of the present invention is that the power supply state switching unit includes a plurality of power line side connection parts connected to each of the plurality of power lines and a charging device side connection part connected to the charging device. By changing the combination of connections between the plurality of power line side connection parts and the charging device side connection part, the connection state between the plurality of power lines and the charging device is configured to be switchable.

[0020] According to this configuration, for example, just by a building manager or the like performing a combination change operation of changing the combination of connections between a plurality of power line side connection parts and the charger side connection parts, the connection state between the plurality of power lines and the charger can be switched. Therefore, the switching operation of the connection state between the power lines and the charger can be easily performed. Moreover, it is not necessary to provide a control configuration or the like for switching the connection state between the power lines and the charger, and simplification of the configuration and cost reduction can be achieved.

[0021] A fourth characteristic configuration of the present invention lies in that an artificial operation type power supply interruption operation part for interrupting the power supply from the power line in the connection state to the charger is provided.

[0022] According to this configuration, for example, when the charger is not in use, the user of the exclusive part can stop the power supply from the power line in the connection state to the charger by artificially operating the power supply interruption operation part, thereby preventing the charger from being used by others. Moreover, in order to interrupt the power supply from the power line in the connection state to the charger, the user of the exclusive part only needs to operate the power supply interruption operation part, and the operability is also good.

Embodiments for Carrying Out the Invention

[0024] An embodiment of the charging system according to the present invention will be described based on the drawings. 〔First Embodiment〕 As shown in FIG. 1, this charging system 1 is provided in a building 3 having a plurality of exclusive parts 2, and is for the user of the exclusive part 2 or the like to charge the vehicle 5.

[0025] In FIG. 1, as an example of the building 3, an apartment building having a plurality of dwellings is shown, and as the exclusive parts 2, three dwellings, i.e., Room 101 21, Room 102 22, and Room 103 23, are shown. As the building 3, not only apartment buildings and condominiums having a plurality of dwellings, but also various buildings having a plurality of exclusive parts such as office buildings and commercial buildings having a plurality of tenants can be applied.

[0026] As shown in FIG. 1, in the charging system 1, a dedicated charging device 4 is installed, and a plurality of parking spaces 6 with charging devices where the vehicle 5 can be parked are provided. The vehicle 5 is not limited to automobiles such as electric vehicles and hybrid vehicles, and vehicles having a power storage device such as various lithium-ion batteries, such as electric motorcycles, electric bicycles, and electric kick scooters, can be applied.

[0027] The parking space 6 with a charging device can be applied to various parking lots, such as a flat parking lot provided with a plurality of adjacent parking spaces on the ground, or a multi-story parking lot provided with a plurality of parking spaces arranged in the vertical or horizontal direction. Regarding the parking space 6 with a charging device, it is preferably arranged inside the building 3 or in an adjacent location of the building 3. However, for example, it can also be arranged at a location far from the building 3, and the location where the parking space 6 with a charging device is arranged can be appropriately changed.

[0028] In FIG. 1, as the parking space 6 with a charging device, three parking spaces 6 with charging devices are provided, i.e., the first parking space 61 with a charging device where the first charging device 41 is installed, the second parking space 62 with a charging device where the second charging device 42 is installed, and the third parking space 63 with a charging device where the third charging device 43 is installed. However, the number of parking spaces 6 with charging devices provided can be appropriately changed.

[0029] As shown in Fig. 1, in the charging system 1, in order to supply power from each of a plurality of exclusive parts 2 to each of a plurality of charging devices 4, a plurality of power lines 8 branched from the secondary side of a watt-hour meter 7 corresponding to each of the plurality of exclusive parts 2 and capable of supplying power, and a power supply state switching unit 9 for supplying power from the power line 8 in the connected state to the charging device 4 are provided.

[0030] In each of the plurality of exclusive parts 2, a distribution board 10 is provided on the secondary side of the watt-hour meter 7. Each of the plurality of power lines 8 is branched from the distribution board 10 and connected to the power supply state switching unit 9. In Fig. 1, since three exclusive parts 2 of Room 101 to Room 103 21 to 23 are illustrated, as the power lines 8, a first power line 81 corresponding to Room 101 21, a second power line 82 corresponding to Room 102 22, and a third power line 83 corresponding to Room 103 23 are shown.

[0031] In the building 3, in addition to the plurality of exclusive parts 2, a common part 11 is provided. In order to enable power supply from the common part 11 to the charging device 4 as well, a power line 84 for the common part branched from the secondary side of the watt-hour meter 7 in the common part 11 and capable of supplying power is provided. The power line 84 for the common part is branched from the distribution board 10 and connected to the power supply state switching unit 9 in the same manner as the first to third power lines 81 to 83 in the exclusive part 2.

[0032] As the power lines 8, the first to third power lines 81 to 83 in the exclusive part 2 and the power line 84 for the common part in the common part 11 are provided, and each of these power lines 81 to 84 is branched from the distribution board 10. However, for example, as shown by the dotted line in Fig. 1, each of the power lines 81 to 84 can also be arranged to be branched from the watt-hour meter 7.

[0033] The power supply state switching unit 9 supplies power from a specific power line 8 to a specific charging device 4 by connecting a specific power line 8 among the plurality of power lines 8 including the power line 84 for the common part and a specific charging device 4 among the plurality of charging devices 4. The power supply state switching unit 9 is configured to be able to freely switch the connection state between the plurality of power lines 8 and the plurality of charging devices 4 that determines which power line 8 is connected to which charging device 4.

[0034] In order to switch the connection state between a plurality of power lines 8 and a plurality of charging devices 4, as shown in FIG. 2, the power supply state switching unit 9 is provided with an operation unit 91. This operation unit 91 is used when an administrator or the like of the building 3 performs a connection state setting operation or a connection state release setting operation. The connection state setting operation is an operation for setting the connection state between a plurality of power lines 8 and a plurality of charging devices 4, and the connection state release setting operation is an operation for releasing the connection state between a plurality of power lines 8 and a plurality of charging devices 4. For example, the power supply state switching unit 9 is housed in a housing or the like, and a key is provided on the housing so that only an administrator or the like of the building 3 can operate the operation unit 91 of the power supply state switching unit 9 and the like.

[0035] As shown in FIG. 2, the operation unit 91 is provided with a connection button 92, a release button 93, a building side selection button 94, a parking space side selection button 95, a decision button 96, and a cancel button 97.

[0036] The connection button 92 is for switching to a state for performing a connection state setting operation for setting a connection target. The release button 93 is for switching to a state for performing a connection state release operation for releasing the connection target in the connection state. The building side selection button 94 is for selecting a connection target on the building 3 side, and is provided with buttons such as "room number", "101", "102", "103", and "common area". The parking space side selection button 95 is for selecting a connection target on the side of the parking space 6 with a charging device, and is provided with buttons such as "parking space", "No. 1", "No. 2", and "No. 3". Incidentally, the parking space side selection button 95 may be a button for specifying the charging device 4 such as "No. 1" or "No. 2" of the charging device 4 arranged in the parking space 6 with a charging device.

[0037] For example, when performing a connection state setting operation to connect a power line 8 in a certain proprietary section 2 and a charging device 4 in a parking space 6 with a charging device, for example, an administrator of the building 3 or the like switches to a mode in which the connection button 92 is pressed to perform the connection state setting operation. In order to select the proprietary section 2 to be connected, after pressing the "room number", the button for selecting the proprietary section 2 to be connected, such as "101" or "102", is pressed. In order to select the parking space 6 with a charging device to be connected, after pressing "parking space", the button for selecting the parking space 6 with a charging device to be connected, such as "No. 1" or "No. 2", is pressed. In this way, by selecting the proprietary section 2 on the building 3 side to be connected and the parking space 6 with a charging device and pressing the determination button 96, the power supply state switching unit 9 switches to the connection state for the parking space in which the power line 8 corresponding to the selected proprietary section 2 and the charging device 4 in the selected parking space 6 with a charging device are in a connected state.

[0038] In FIG. 1, as shown by the solid line arrows, the first power line 81 in the 101st room 21 and the first charging device 41 in the first parking space 61 with a charging device are in a connected state, the second power line 82 in the 102nd room 22 and the second charging device 42 in the second parking space 62 with a charging device are in a connected state, and the third power line 83 in the 103rd room 23 and the third charging device 43 in the third parking space 63 with a charging device are in a connected state.

[0039] For example, when performing a connection state release setting operation to release the connection state between the power line 8 in a certain exclusive section 2 and the charging device 4 of a parking space 6 with a charging device, for example, an administrator of the building 3 or the like switches to a mode in which the connection state release setting operation of setting the object to be disconnected by pressing the release button 93 is performed. After pressing the "room number", the button for selecting the exclusive section 2 to be disconnected, such as "101" or "102", is pressed. After pressing the "parking space", the button for selecting the parking space 6 with a charging device to be disconnected, such as "No. 1" or "No. 2", is pressed. In this way, by selecting the exclusive section 2 on the building 3 side and the parking space 6 with a charging device to be disconnected and pressing the determination button 96, the power supply state switching unit 9 releases the connection state between the power line 8 corresponding to the selected exclusive section 2 and the charging device 4 in the selected parking space 6 with a charging device.

[0040] Since the power supply state switching unit 9 only switches the connection state between a plurality of power lines 8 and a plurality of charging devices 4 based on a manual operation using the operation unit 91, it can switch the connection state between a plurality of power lines 8 and a plurality of charging devices 4 with only a simple configuration such as a power switch without having a special control configuration.

[0041] When the user of the exclusive section 2 wants to charge the vehicle 5 with the charging device 4, a contract such as a lease contract for using the parking space 6 with a charging device is concluded with the administrator of the building 3 or the like. The content of the contract becomes the parking space use information that determines the parking space 6 with a charging device that can be used by the user of the exclusive section 2 in a state where the exclusive section 2 and the parking space 6 with a charging device are specified. The administrator of the building 3 or the like performs a connection state setting operation and a connection state release setting operation using the operation unit 91 based on the parking space use information. Therefore, the power supply state switching unit 9 switches to the connection state for the parking space in which the power line 8 corresponding to the specified exclusive section 2 and the charging device 4 corresponding to the specified parking space 6 with a charging device are connected based on the parking space use information.

[0042] For example, a user of Room 101 21 has contracted to use the parking space 61 with the first charging device, a user of Room 102 22 has contracted to use the parking space 62 with the second charging device, and a user of Room 103 23 has contracted to use the parking space 63 with the third charging device. In this case, the administrator of the building 3 or the like performs a connection state setting operation and a connection state release setting operation using the operation unit 91 based on the parking space usage information which is the content of the contract. Therefore, as shown by the solid arrows in FIG. 1, the power supply state switching unit 9 switches to the connection state for the parking space that connects the first power line 81 corresponding to Room 101 21 and the first charging device 41 corresponding to the parking space 61 with the first charging device, switches to the connection state for the parking space that connects the second power line 82 corresponding to Room 102 22 and the second charging device 42 corresponding to the parking space 62 with the second charging device, and switches to the connection state for the parking space that connects the third power line 83 corresponding to Room 103 23 and the third charging device 43 corresponding to the parking space 63 with the third charging device.

[0043] The user of Room 101 21 can park the vehicle 5 in the parking space 61 with the first charging device and charge the vehicle 5 with the first charging device 41. Similarly, the user of Room 102 22 can park the vehicle 5 in the parking space 62 with the second charging device and charge the vehicle 5 with the second charging device 42, and the user of Room 103 23 can park the vehicle 5 in the parking space 63 with the third charging device and charge the vehicle 5 with the third charging device 43. FIG. 1 shows the case where the vehicle 5 is parked only in the parking space 63 with the third charging device.

[0044] When the user of Room 101 21 parks the vehicle 5 in the parking space 61 with the first charging device and charges the vehicle 5 with the first charging device 41, the first watt-hour meter 71 corresponding to Room 101 21 can also measure the power consumption during charging. Therefore, for example, by billing the total power consumption of the user of Room 101 21 including the power consumption, it is possible to perform billing according to the power consumption during charging. Incidentally, by providing a separate watt-hour meter on the path of the power line 8, the power consumption during charging can be grasped.

[0045] Since the users of the exclusive section 2 where the first charging device-equipped parking space 61 can be used are limited to the users of Room 21 on the 101st floor, the users of Room 21 on the 101st floor can exclusively use the first charging device 41. Therefore, the users of Room 21 on the 101st floor can freely use the first charging device 41 and charge the vehicle 5 whenever they want, without considering the usage status of other charging devices 4.

[0046] In FIG. 1, the case where the user of the exclusive section 2 has contracted to use one charging device-equipped parking space 6 is illustrated. However, for example, it is also possible to contract to use a plurality of charging device-equipped parking spaces 6, such as when the user of the exclusive section 2 uses two charging device-equipped parking spaces 6.

[0047] In this case, for example, a plurality of power lines 8 will be provided in a state where a plurality of power lines 8 are wired from one exclusive section 2. The administrator of the building 3 or the like performs a connection state setting operation and a connection state release setting operation using the operation unit 91 based on the parking space usage information that is the contract content. The power supply state switching unit 9 switches to a connection state for the parking space that connects the power line 8 corresponding to the specified exclusive section 2 and the charging device 4 corresponding to the specified charging device-equipped parking space 6 based on the parking space usage information, and can connect one charging device 4 to each of the plurality of power lines 8 in one exclusive section 2. Thereby, for example, even when the user of a certain exclusive section 2 owns a plurality of vehicles 5, each of those plurality of vehicles 5 can be charged simultaneously by the charging device 4.

[0048] As shown in FIG. 1, the building 3 is provided with a shared section 11 in addition to a plurality of exclusive sections 2, and a power line 84 for the shared section corresponding to the shared section 11 is provided. Therefore, the power supply state switching unit 9 is configured to be switchable to a connection state for the shared section that connects the power line 84 for the shared section and any one of the plurality of charging devices 4, as indicated by the dotted arrow in FIG. 1.

[0049] For example, regarding the parking space 63 with the third charging device, when the user of the exclusive part 2 that can be used is not determined, the administrator of the building 3 or the like can allow a person other than the user of the exclusive part 2 to use the parking space 63 with the third charging device. At this time, as shown in FIG. 2, the administrator of the building 3 or the like performs a connection state setting operation for connecting the shared part power line 84 and the third charging device 43 corresponding to the parking space 63 with the third charging device in a state where the "shared part" button and the "No. 3" button are pressed using the operation unit 91. Therefore, based on the connection state setting operation, the power supply state switching unit 9 switches to the shared part connection state in which the shared part power line 84 and the third charging device 43 corresponding to the parking space 63 with the third charging device are connected, as indicated by the dotted arrow in FIG. 1.

[0050] In this case, a person other than the user of the exclusive part 2 can park the vehicle 5 in the parking space 63 with the third charging device and charge the vehicle 5 with the third charging device 43. At this time, the power consumption meter 74 for the shared part corresponding to the shared part 11 can also measure the power consumption during charging, and the total power consumption including the power consumption can be grasped. Therefore, it is possible to perform charging considering the total power consumption, such as the amount set by the administrator of the building or the like. Incidentally, by separately providing a power consumption meter on the path of the shared part power line 84, the power consumption during charging can be grasped, and charging considering the power consumption can be performed.

[0051] In this way, the administrator of the building 3 or the like can not only allow the user of the exclusive part 2 to use the plurality of parking spaces 6 with charging devices, but also allow a person other than the user of the exclusive part 2 to use them. Therefore, it becomes a charging system 1 that can effectively utilize the plurality of parking spaces 6 with charging devices.

[0052] In the distribution board 10 in the plurality of exclusive parts 2 and the common part 11, there is provided an artificially operable breaker 12 (corresponding to a power supply interruption operation part) for interrupting the power supply by the power line 8. Thus, when the charging device 4 is not in use, the user of the exclusive part 2, the administrator of the building 3, etc. can artificially operate the breaker 12 to stop the power supply from the power line 8 in the connected state to the charging device 4, thereby preventing others from using the charging device 4. Further, the user of the exclusive part 2 can reduce the risk of power theft by turning on and off the power supply at locations such as the breaker 12 and switches within the exclusive part 2 and locking the key on the charging device 4 side.

[0053] 〔Second Embodiment〕 This second embodiment is another embodiment of the power supply state switching unit 9, and other configurations and the like are the same as those in the first embodiment. Hereinafter, the power supply state switching unit 9 in the second embodiment will be mainly described, and the description of other configurations and the like will be omitted by using the same reference numerals.

[0054] In the first embodiment, an example was given in which the power supply state switching unit 9 includes the operation unit 91 shown in FIG. 2. On the other hand, in the second embodiment, as shown in FIG. 3, the power supply state switching unit 9 is provided with a plurality of power line side connection parts 101 connected for each of the plurality of power lines 8 and a plurality of charging device side connection parts 111 connected for each of the plurality of charging devices 4.

[0055] The power line side connection part 101 is constituted by a socket connected for each of the plurality of power lines 8, the charging device side connection part 111 is constituted by a wiring power plug connected for each of the plurality of charging devices 4, and the charging device side connection part 111 is provided so as to be pluggable into the power line side connection part 101. For short - circuit prevention, it is preferable to make the power line side connection part 101 the female side of the socket. The power line side connection part 101 and the charging device side connection part 111 may be arranged so as to be accommodated in the same board, or may be arranged so as to be accommodated in separate boards, and how to arrange them can be appropriately changed.

[0056] As the power line side connection part 101, as shown in FIGS. 1 and 3, there are provided a first outlet 102 corresponding to the first power line 81 of the 101st room 21, a second outlet 103 corresponding to the second power line 82 of the 102nd room 22, a third outlet 104 corresponding to the third power line 83 of the 103rd room 23, and a shared part outlet 105 corresponding to the shared part power line 84 of the shared part 11. When the power line side connection part 101 is not used, a cover member or the like is attached to the power line side connection part 101.

[0060] A display such as "parking space" is provided for the charging device side connection portion 111 so that it can be grasped that it is on the side of the parking space 6 with a charging device. For the first to third wiring power plugs 112 to 114, displays such as "No.1", "No.2", "No.3", etc. are provided so that it can be grasped which parking space 6 with a charging device they correspond to. Incidentally, the display of the first to third wiring power plugs 112 to 114 may be a display for specifying the charging device 4 such as "No.1" or "No.2" of the charging device 4 arranged in the parking space 6 with a charging device.

[0061] As described above, since the power line side connection portion 101 and the charging device side connection portion 111 have displays that can identify each of them, the administrator of the building 3 or the like can easily visually recognize the current connection state. Therefore, it is possible to prevent accidentally connecting a plurality of private parts 2 and the charging device 4.

[0062] Regarding the power line side connection portion 101, a case is illustrated in which one charging device side connection portion 111 is provided for each of a plurality of private parts 2. For example, for each of a plurality of private parts 2, a plurality of two charging device side connection portions 111 or the like can be provided. Thereby, for example, even when a user of a certain private part 2 owns a plurality of vehicles 5, each of those plurality of vehicles 5 can be charged simultaneously by the charging device 4.

[0063] 〔Another Embodiment〕 Another embodiment of the present invention will be described. Note that the configurations of the embodiments described below are not limited to being applied individually, and can also be applied in combination with the configurations of other embodiments.

[0064] (1) In the above embodiment, the number of parking spaces 6 with charging devices is the same as the number of exclusive parts 2. However, for example, it is also possible to provide parking spaces 6 with charging devices that are fewer than the number of exclusive parts 2, or to provide parking spaces 6 with charging devices that are more than the number of exclusive parts 2. Regardless of the number of exclusive parts 2, the number of parking spaces 6 with charging devices can be set.

[0065] (2) In the above embodiment, the breaker 12 provided in the distribution board 10 is used as the power supply interruption operation unit. However, on the building 3 side, a power supply interruption operation switch or the like can be provided separately from the breaker 12, and how to configure the power supply interruption operation unit can be appropriately changed.

[0066] (3) In the first embodiment, the power supply state switching unit 9 that switches the connection state between the plurality of power lines 8 and the plurality of charging devices 4 according to the operation of the operation unit 91 is exemplified. In the second embodiment, the power supply state switching unit 9 that switches the connection state between the plurality of power lines 8 and the plurality of charging devices 4 by changing the combination of connections between the plurality of power line side connection parts 101 and the plurality of charging device side connection parts 111 is exemplified. However, as the power supply state switching unit 9, any configuration can be applied as long as it switches the connection state between the plurality of power lines 8 and the plurality of charging devices 4 based on the parking space usage information.
