Description

  The present invention relates to an electric vehicle charging system for charging an electric vehicle.

  It is well known that mobiles that run on electric motors (hereinafter also referred to as batteries), such as electric cars and electric bicycles, are effective for effective use of earth resources such as oil and CO2 reduction to prevent global warming. Is the fact of For automobiles that run on oil, there is a gas station etc. as a conventional refueling method, but electric vehicles and bicycles (hereinafter, these mobiles are collectively referred to as “electric vehicles”) are equipped with storage batteries. Need to be charged. Charging this electric vehicle takes more time than refueling compared to oil, light oil, and the like.

  For this reason, an electric vehicle is used in the parking lot of each household that owns it, and in apartment buildings such as condominiums, it can be used individually when the vehicle is not driven by using a shared site such as the parking lot or a charging space. It is thought that it is often charged. The reason for this is that, as an electric vehicle possession method, a shared system such as so-called car sharing is adopted in an apartment house such as an apartment, where one electric vehicle is unspecified and shared among multiple households. But the same is true.

  In a housing complex such as a condominium, it is necessary to efficiently charge a plurality of electric vehicles in a parking lot allocated to each household or a charging space provided exclusively for charging. In Patent Document 1 below, in order to charge a plurality of electric vehicles, one rectifier is provided as a common DC power source for the plurality of chargers, and the set charger among the chargers is time-divisionally divided. By controlling the charging, the cost of the charging system is reduced and the size is reduced.

JP 05-336673 A

  In the configuration described in Patent Document 1 described above, a plurality of electric vehicles are intended to be charged in a time-sharing manner using a charger that originally has a charging capacity for one unit. Although it is considered that multiple electric vehicles can be charged with power consumption, eventually the charging time is long or the electric vehicle of one electric vehicle is incompletely charged and the electric vehicle is used. It may be necessary.

  In addition, the following problems are expected for simultaneous charging of a plurality of electric vehicles.

  At present, the current capacity of a 100V commercial AC power source required for charging one electric vehicle is considered to be about 10 to 15 A. For example, all the chargers installed in a parking lot or a charging space are simultaneously moved. This may not be possible in view of the current capacity of the entire apartment. In this case, for example, it is conceivable to perform an operation of limiting the number of units that can be used simultaneously to about 3 to 5 units out of 10 chargers installed in a parking lot or a charging space. In such a system, when the number of simultaneous charging reaches the limit, a user who newly applies for charging is allowed to connect an electric vehicle to the charger and perform a setting operation. However, the electric car must wait for charging.

  In this way, when operating an electric vehicle charging system to limit the number of electric vehicles that can be charged simultaneously, the system efficiently performs simultaneous charging and terminates the current charging as quickly as possible. If there is an electric vehicle waiting for charging, it must be able to start charging immediately.

  For example, the space for charging an electric vehicle is limited, and in an operation mode in which the next electric vehicle cannot be charged unless the electric vehicle that has been charged is moved from the charging space, the battery is quickly charged. In order to move a terminated electric vehicle from the charging space, the resident who applied for the charging service is informed of charging service information such as the charging status and charging end time, and the charging end timing is clearly indicated. Notification is required.

  On the other hand, collective housing such as condominiums have postal receipts, delivery storage devices, and so-called delivery boxes (hereinafter referred to as delivery boxes for the sake of brevity). May be installed. A parcel delivery box is an article storage (acquisition) device similar to a locker having a plurality of lockable article storage boxes for receiving parcels delivered to a specific resident or for collecting parcels delivered by a specific resident It is. This article storage box may be used in common by residents, but there may also be a usage form in which one article storage box is allocated exclusively to each resident. It can also be used for receiving goods.

  In this type of delivery box, the unlocking (or locking) necessary for taking in / out delivery packages to / from a plurality of article storage boxes is controlled by a control circuit that controls the operation display unit using a touch panel or the like. For example, an ID card (IC card or the like) is assigned to the resident as an authentication means, and when the resident performs an operation of taking out and putting in a parcel delivery to the article storage box, the ID card is presented on the operation display unit. Thus, the control circuit performs control so that the intended operation can be performed by proving that the user is a legitimate package receiver (or shipper) and performing a predetermined operation thereon. The delivery box operation performed in this way can be recorded and managed as usage information in a database or the like together with the resident identification information indicated by the time and the ID card. Usage information managed by the delivery box can be stored in the storage means of the control circuit, displayed on the operation display unit as needed, or transferred to a remote management center via a network. .

  In recent years, apartments such as condominiums equipped with this type of delivery box have increased, and the control circuit, storage means, and database means of the delivery box configured as described above are used for each resident through an ID card or the like. If such a system can be used to manage not only the delivery box but also the charging operation and the charge (billing) information of the above-mentioned electric vehicle, the convenience of the resident will increase. In addition, since the delivery box control system and the electric vehicle charging control system can be shared, it is considered that the overall cost required for the entire facilities and system management required for the apartment house can be expected.

  In apartments such as condominiums, settings related to charging and billing are made via the parking lot assigned to each household or the operation panel of the charging system installed in the charging space dedicated to charging. In many cases, information related to the charging service, such as the state of charge of the electric vehicle, is displayed via an indicator of the charger or an operation panel of the charging system.

  However, it is normal that the parking lot allocated to each household or the charging space provided exclusively for charging is located away from each room, and in the configuration as described above, charging of the electric vehicle was started. Also, there is a problem that it is necessary to go to the parking lot and the charging space for display information such as the operation panel of the charging system and the indicator of the charger.

  In the delivery box system as described above, it is considered that the arrival status is notified by using the intercom in the resident's room. For example, the control of the delivery system of the delivery box system and the charging system of the electric vehicle is integrated. Accordingly, there is a possibility that information regarding the charging service of the electric vehicle can be directly notified to the resident in the apartment room using the intercom of the resident's room.

  The subject of the present invention is that, from the above viewpoint, a plurality of electric vehicles can be efficiently charged in a parking lot and a charging space such as an apartment house, and information on the electric vehicle charging service is provided to residents in the apartment house room. An object is to provide an electric vehicle charging system capable of direct notification.

  In order to solve the above-mentioned problems, in the present invention, an article receiving apparatus including a plurality of article storage boxes that are opened and closed by an electric lock used for collection of parcels or mail in an apartment house, and the electricity of the article receiving apparatus. A control means for controlling opening and closing of the lock; a power supply circuit for charging the electric vehicle; a charge control section for controlling the power supply circuit; and an interphone arranged in a room of a resident of the apartment house, wherein the control means In addition to controlling the opening and closing of the electric lock of the article receiving apparatus, the charging control of the electric vehicle performed through the power supply circuit and the charging control unit is performed, and the charging service of the electric vehicle to the resident A configuration is adopted in which information is notified via the intercom placed in the room of the resident.

  According to the above configuration, since the control unit of the article receiving device performs control related to the charging service for the electric vehicle, the article receiving device control system and the electric vehicle charging control system can be shared, and the article By centralizing the control of the toll device and the charging control of the electric vehicle, it is possible to reduce the contract electricity charge necessary for the apartment house and to reduce the overall cost required for the overall equipment and system management. In addition, the charging management information of the electric vehicle, the information about the charging state, the registration information of the charging service, that is, various information about the charging service are used not only for the display operation unit used for the management and use of the article storage box but also for the resident Since notification can be made via the intercom in the room, there is no need to check the position of the display operation unit used for the use and management of the article storage box, or the parking lot or the charging space. However, there is an excellent effect that it is possible to acquire the charge management information or the information about the charging service.

  Hereinafter, as an example of a mode for carrying out the present invention, an embodiment relating to a charging system for an electric vehicle suitable for implementation in an apartment house such as an apartment will be described with reference to the accompanying drawings.

  FIG. 1 shows a main configuration of an electric vehicle charging system employing the present invention, and FIG. 2 shows an overall configuration of the system.

  Hereinafter, a hardware configuration of an electric vehicle charging system employing the present invention will be described with reference to FIGS. 1 and 2.

  The electric vehicle charging system according to the present embodiment is installed in a housing complex such as a condominium. As shown in FIG. 2, charging receptacles 205, 205... Chargers 207, 207... Are included.

  A plurality of parking spaces 208 are illustrated, and these are allocated to each resident, and are used exclusively by electric vehicles (including electric bicycles) owned by each resident or other parking spaces. It may be a common charging space where a resident moves from the position and only performs charging. The electric vehicle to be charged may be owned by each resident, or may be shared (car sharing) by the resident of the apartment house. When the electric vehicle to be charged is shared (car sharing), the electric vehicle is reserved and managed through a predetermined reservation procedure.

  In the charging system of the present embodiment, the control circuit (FIG. 1) of the delivery box 100 is used for charging control. As shown in FIG. 2, the delivery box 100 has an operation display unit 151 that is operated when a condominium resident receives and delivers a delivery item, or inquires about charge management or a charge service, which will be described later. Further, the operation display unit 151 includes a card interface for reading an ID card (IC card or the like) as an authentication means for a resident (or a courier).

  A key box 160 is arranged at the bottom of the operation display unit 151. This key box 160 is used for car sharing. For example, an electric vehicle is reserved through a predetermined reservation procedure. Then, the key of the electric vehicle is delivered to the user via the key box 160.

  The home delivery box 100 is connected to charging hardware such as charging receptacles 205, 205... And medium speed chargers 207, 207.

  The control circuit (FIG. 1) of the delivery box 100 is connected to a remote management system 401 via the Internet (or a network using a dedicated line or public line) 400. The charge control described later (or part or all of the delivery box control) can also be executed by this management system, but in this embodiment, the remote management system 401 executes control related to charging of the charging fee. To do.

  This management system 401 is connected to a charging system 402 having an interface 403 with, for example, a bank account withdrawal system, for example. Based on charging management information described later recorded in the management form database, the management system 401 is connected via the charging system 402. Charging can be charged. However, the interface 403 may not be a system for communicating with a bank account withdrawal system or the like, but may be a system for issuing an invoice for a charging fee (for example, a condominium management association). .

  Further, the management system 401 has a database 442 used for data management other than those related to billing. The database 442 can store and manage information necessary for charging control of the electric vehicle, statistical information on the use status of the delivery box, and the like. For charging control of electric vehicles, charging control information according to the vehicle type of the electric vehicle, such as necessary current and current control pattern according to the vehicle type, charging termination conditions, etc. are stored and used for charging control of the electric vehicle It is possible to do.

  In this embodiment, the control circuit of the delivery box 100 is connected to an interphone 441 arranged in each room of an apartment house such as an apartment where the delivery box 100 is arranged.

  As is well known, this intercom 441 is arranged mainly for the purpose of calling a guest by pressing a room number on a call control panel (not shown) arranged at the entrance of a so-called auto-lock apartment. . The interphone 441 of this embodiment is provided with a display unit including a liquid crystal display.

  The display device of the interphone 441 is used for displaying the video of the surveillance camera arranged at the entrance and making the image of the visitor visible as is well known. The control system of the delivery box 100 as in this embodiment is used. When a delivery item arrives for a resident in the room, the fact can be notified through voice or text display of the intercom 441.

  Furthermore, in this embodiment, particularly for a corresponding resident who applied for charging an electric vehicle, the charge management information of the electric vehicle, for example, a charging start time as described below, using the display of the resident's interphone 441, It can be used to display information about the charging service such as the charging end time.

  FIG. 1 shows a detailed configuration example when the overall configuration of FIG. 2 is implemented. The block indicated by reference numeral 100 in FIG. 2 substantially corresponds to the delivery box 100 in FIG. 2, and the circuit shown in this block corresponds to the control circuit of the delivery box 100, and controls for controlling only the conventional delivery box. The configuration is almost compatible with the circuit.

  In this embodiment, the charging control unit 200 for charging the electric vehicle 300 (illustrated in the form of an automobile) is shown as a separate block from the delivery box 100, and this part is accommodated in the housing of the delivery box 100, or It is arranged at a predetermined position in the vicinity of the parking space 208.

  Hereinafter, the control circuit of the delivery box 100 in FIG. 1, the charging control unit 200 that charges the electric vehicle 300 and its peripheral circuits will be described in order.

  The control means of the delivery box 100 is mainly used as a delivery box control unit 101 configured by using a CPU such as a microprocessor, a ROM 121 storing a control procedure described later, and a work area for executing a control procedure described later. The RAM 122 is configured. The interface 103 includes a network interface for communicating with the management system 401, an interface for communicating with the interphone 441, an interface for communicating with the operation display unit 151 (not shown in FIG. 1) in FIG.

  The reference numeral 104 is composed of a plurality of article storage boxes, and each of these article storage boxes is usually a door arranged on the public side of the apartment (mainly) opened and closed by the courier and a private apartment opened by the resident. It has a door arranged on the (common part) side, and further has electric locks 1042 and 1043 for locking / unlocking these two doors.

  Here, a resident does not occupy one article storage box. For example, each delivery is shared so that the delivery company designates the destination of a delivery item stored in a specific article storage box using the operation display unit on the public side. Although a method is also conceivable, in this embodiment, for ease of explanation, one article storage box is assigned to each resident (living room).

  Further, each article storage box has a display unit 1041. The display unit 1041 is configured by using an LCD, an LED, or the like, and can take display states such as character display, blinking, lighting, and extinguishing. Depending on these display states, the state of the article storage box, for example, the article storage box is displayed. In addition to displaying various states relating to the article storage box, such as whether or not the delivery item has arrived (accommodated), in this embodiment, it is also possible to display information relating to the charging service of the electric vehicle.

  The home delivery box control unit 101 presents the operation display unit 151 with an ID card when a resident (or home delivery company) performs a delivery operation of a home delivery package or the like with respect to the article storage box, as in the conventional home delivery box. Authentication control and unlocking / locking control of the electric locks 1042 and 1043 based on the authentication control are performed.

  The delivery box control unit 101 has an interface 102 for communicating with the charging control unit 200. In addition, the charging control unit 200 includes an interface 203 having a corresponding specification. The specification of the communication interface between the delivery box control unit 101 and the charging control unit 200 is arbitrary, and for example, an interface using a bundle of appropriate control lines or a network interface such as IEEE802.3 can be used.

  The charging control unit 200 (master unit) includes a delivery box control unit 101 (CPU) that constitutes a delivery box control circuit, a control circuit 201 including a ROM 121, a RAM 122, and the like, and a power supply circuit 202. For example, in the simplest configuration, the power supply circuit 202 outputs the output of a commercial AC power supply (not shown) such as a single-phase / 3-phase (100 V, 220 V, etc.) based on the control of the control circuit 201. And a switch circuit for supplying to the medium-speed charger 207 (only one charging receptacle 205 and one medium-speed charger 207 are shown).

  The charging receptacle 205 can be connected to a plug 301 at the tip of the charging cable 302 extending from the charging circuit 308 of the electric vehicle 300 on which the battery 304 is mounted, and is used to supply the output of the power supply circuit 202 to the charging circuit 308. .

  In the present embodiment, the charging receptacle 205 is exemplified as the charging output means, but the configuration of the charging output means (outlet) is arbitrary, and the charging output means (outlet) is used by being connected to the charging connector on the electric vehicle side. It goes without saying that the present invention can also be implemented using such means as a cable gun.

  In the present embodiment, the charging receptacle 205 and the charging connector of the charging circuit of the electric vehicle are connected by the charging cable to perform charging. However, the present embodiment is also applied to the configuration in which the battery removed from the electric vehicle is charged. Of course, the invention can be implemented, in which case the charging output means can be replaced with any configuration suitable for the subject battery, such as a cable with an alligator clip.

  The charging receptacle 205 is equipped with a card reader 211 for performing authentication for charging at the position of the charging receptacle 205 as described later. The card reader 211 is provided with a card interface for reading an ID card (IC card or the like) presented by a resident and a display (details not shown) using an LCD or the like.

  The charging circuit 308 of the electric vehicle 300 includes a rectifying circuit that converts a charging AC input input from the cable 302 into a direct current for charging the battery 304, and the battery 304 according to various conditions such as a charging amount of the battery 304. It is composed of a current control circuit that can obtain a charging current suitable for charging, and a charging control circuit that monitors the amount of charge of the battery 304 and shuts off the input from the cable 302 when the battery is fully charged. The

  The medium-speed charger 207 includes a charging circuit for charging the battery 304 or the like removed from the electric vehicle 300 in a short time. The medium-speed charger 207 is constituted by a charging circuit that can obtain a low-voltage DC charging output configured to obtain a charging current / voltage curve that can efficiently charge the battery 304 in a short time, for example.

  In order to fully charge the battery 304 of the electric vehicle 300 (using the charging receptacle 205), a long charging time such as one day and night may be required. However, such a medium speed charger 207 is provided. Thus, in a situation where only a short traveling time is expected, it is possible to perform charging as much as necessary in a short charging time. The medium-speed charger 207 is also equipped with a card reader 211 for performing authentication for charging at that position.

  The charging receptacle 205, the medium-speed charger 207, and their card reader 211, the control circuit 201, and the power supply circuit 202 are connected by a cable 204.

  Next, the operation of the charging system configured as described above will be described with reference to FIGS. Hereinafter, charging of the electric vehicle 300 using the charging receptacle 205 will be described as an example. For charging using the medium-speed charger 207, a plug of the cable 302 drawn from the electric vehicle 300 to the charging receptacle 205 is described. Instead of connecting 301, the battery (304) is connected to the medium-speed charger 207 using a cable (not shown), and the authentication using each card reader 211 is the same. Shall be omitted.

  3 to 7 show the control procedure of this charging system. FIG. 3 shows the charging control procedure of the control circuit 201 of the charging control unit 200, FIG. 4 shows the charging control procedure of the delivery box control unit 100, FIG. 5 shows the charge monitoring procedure of the delivery box control unit 100, respectively. 6 shows an inquiry control procedure controlled by the delivery box control unit 100, FIG. 7 shows a charging condition setting control procedure controlled by the delivery box control unit 100, and FIG. 8 shows a delivery box control unit in each of the above procedures. A control table used by 100 is shown.

  The control procedure of the delivery box control unit 100 can be stored in the ROM 121 as a control program for the CPU constituting the delivery box control unit 100. The control procedure of the control circuit 201 of the charge control unit 200 is controlled by As a control program for the CPU constituting the circuit 201, it can be stored in an equivalent ROM in the control circuit 201.

  First, control of the control circuit 201 of the charging control unit 200 will be described with reference to FIG. When charging the electric vehicle 300, the resident connects the plug 301 of the cable 302 drawn from the electric vehicle 300 to the charging receptacle 205 in step S101 of FIG. 3, and the resident charges the ID card assigned to him / her to the charging receptacle. The information is presented to a card reader 211 of 205 and ID information (resident identification information) is read.

  In step S <b> 102, the control circuit 201 of the charging control unit 200 communicates with the delivery box control unit 100 via the interfaces 203 and 102, and transmits the ID information read by the card reader 211 to the delivery box control unit 100. The delivery box control unit 100 determines whether or not the received ID information is ID information of a resident who may permit charging of the electric vehicle 300 with reference to table data in FIG. Is returned to the control circuit 201 of the charging control unit 200.

  When the control circuit 201 of the charging control unit 200 receives information indicating that authentication is not possible from the delivery box control unit 100 in step S102, an error is displayed using the display of the card reader 211 in step S103 (further, an operation display is displayed). The same error display may be performed in the part 151).

  In step S104, usage registration related to charging of the electric vehicle 300 is performed. Here, information such as the charging start time and (predicted) charging end time is transmitted to the delivery box control unit 100 to the delivery box control unit 100, and the delivery box control unit 100 associates the information with the previously transmitted ID information. Are stored in the table data of FIG.

  In step S105, the power supply circuit 202 is controlled to turn on its charging AC output, whereby supply of charging current to the charging circuit 308 of the electric vehicle 300 is started (step S106).

  At this time, the charging current pattern and the like can be controlled based on the charge management information of the electric vehicle 300 obtained from the database 442. The charge management information such as the charge current pattern stored in the database 442 can be selected from the vehicle type information of the electric vehicle 300, for example. For this purpose, for example, vehicle type information of the resident's electric vehicle 300 is stored in an ID card presented to the card reader 211, and this is read and the charge management information such as the charging current pattern stored in the database 442 is selected. be able to. In addition, in order to select charge management information such as a charge current pattern stored in the database 442 by providing user interface means such as a keyboard or a display on the card reader 211 and a resident inputs vehicle type information. The vehicle type information of the electric vehicle 300 can be acquired.

  In step S107, monitoring of the charging AC output of the power supply circuit 202 is started. For example, when an abnormality such as a short circuit or leakage is detected, the charging AC output of the power supply circuit 202 is turned off and communication with the delivery box control unit 100 is performed. Then, the occurrence of an error is reported using an error number corresponding to the abnormality that has occurred (step S108). Further, when setting of the maximum charging time described later (step S503 in FIG. 7) is performed, the charging can be terminated in the same manner as an error even when the maximum charging time has elapsed. Further, when the charge management information is obtained from the database 442, the charge management information obtained from the database 442 such as the pulse charge pattern at the initial stage and the end of charge, the charge current decay pattern from the middle stage to the end of charge, and the like. Can be controlled based on

  In step S107, information such as the charging start time and (predicted) charging end time stored in the table data in FIG. 8 in association with the ID information is transmitted to the intercom 441 of the corresponding room and displayed on the display. . This display may be performed when a predetermined inquiry operation is performed on the intercom 441 side, or may be displayed at all times while the intercom 441 (the display device) is not used for other operations. It may be.

  In FIG. 9, reference numeral 901 indicates a display example on the display of the intercom 441. Here, the charging start time (date and time) and the charging end time (date and time) are displayed together with the room number (304) of the corresponding room. .

  On the other hand, when the monitoring of the charging AC output of the power supply circuit 202 is normally completed, the process proceeds to step S109. For example, the charging end timing is determined by the charging circuit 308 of the electric vehicle 300. For example, this type of charging circuit 308 is usually provided with a charging control circuit that monitors the amount of charge of the battery 304 as described above and shuts off the input from the cable 302 when full charging occurs. Therefore, for example, the control circuit 201 and the power supply circuit 202 may monitor the charging AC current and determine that the charging is finished when the charging AC current almost stops flowing. Further, information related to the charging end condition, for example, information such as the elapsed time after the charging current value becomes below a certain level, is stored in the database 442 in association with the vehicle type information, and the charging end condition acquired from the database 442 is stored. The charging end timing may be determined according to the information.

  When the power supply circuit 202 detects the end of charging, in step S109, the control circuit 201 turns off the charging AC output of the power supply circuit 202 (step S110), and reports the end of charging to the delivery box control unit 100 (step S111). The home delivery box control unit 100 generates billing data related to the charging process and records it together with the ID information, or transmits the information to the management system 401 via the Internet 400.

  Further, the end of charging is notified from the delivery box control unit 100 to the interphone 441 in the room of the corresponding resident (step S308 in FIG. 5).

  Note that the billing amount can be calculated by, for example, the charging time calculated from the charging start time and the charging start end time according to the simplest calculation method. Alternatively, the control circuit 201 may constantly capture the output of the current detection circuit provided in the power supply circuit 202, and the total amount of power used for charging may be accumulated and reported to the delivery box control unit 100.

  In step S112, it is determined whether or not an inquiry operation has been performed on the charging process completed as described above via the operation display unit 151 of the delivery box control unit 100 or the like. When this inquiry operation is performed, a later-described inquiry control procedure (FIG. 6) is executed via the operation display unit 151 where the operation is performed.

  Next, the charging control procedure of the delivery box control unit 100 in FIG. 4 will be described.

  In step S201 of FIG. 4, it is determined whether or not ID information (read from the ID card) is transmitted from the control circuit 201 of the charging control unit 200 in step S102 of FIG. 3. In step S202, the delivery box control unit 100 determines whether or not the received ID information is ID information of a resident who may permit charging of the electric vehicle 300 with reference to table data in FIG. . If the authentication is successful, an affirmative response (ACK) is returned in step S203, and if the authentication is unsuccessful, an error response is returned to the control circuit 201 of the charging control unit 200 in step S204.

  When an affirmative response (ACK) is transmitted in step S203, the control circuit 201 of the charging control unit 200 starts the above-described charging process. Therefore, in step S205, a charging flag 803 arranged in a table shown in FIG. Turn on.

  Next, the charge monitoring procedure of the delivery box control unit 100 will be described with reference to FIG. This charging monitoring procedure can be implemented as a timer interrupt process or the like that is periodically started after the charging flag is turned on in the above-described charging control procedure of FIG. Further, it is assumed that the charge monitoring procedure in FIG. 5 is activated for each charge receptacle 205 every time one charge job is started.

  In step S300 in FIG. 5, the display unit 1041 of the delivery box corresponding to the ID card presented in step S101 in FIG. 3 is set in a predetermined lighting state, whereby the charging process started by the resident corresponding to the ID card is performed. It displays that the electric vehicle 300 is being charged. By the display on the display unit 1041, the resident can confirm that the started charging continues by viewing the display unit 1041 of the delivery box assigned to him.

  Subsequently, in step S301, the delivery box control unit 100 determines whether or not a normal charging end report (step S109 in FIG. 3) has been received from the control circuit 201 of the charging control unit 200. If a normal charging end report is received, the process proceeds to step S302.

  In step S302, if a charge end report has not been received, it is determined whether an error report (step S108 in FIG. 3) has been received from the control circuit 201 of the charge control unit 200. If an error report has been received, the process proceeds to step S306.

  If no error report has been received in step S302, in step S308, the delivery box control unit 100 notifies the interphone 441 of the corresponding resident's room from the delivery box control unit 100, and the process returns to step S300. A display example on the display of the intercom 441 at this time is as shown in FIG.

  If the charging end report is received in step S301, the charging flag 803 in FIG. 8 is turned off in step S303, and the corresponding delivery box display unit 1041 is turned off in step S304 (or in a lighting state with a predetermined color). Yes). By visually recognizing the display on the display unit 1041, the resident can confirm that the charging started by the resident has been normally completed.

  On the other hand, if the charging has ended in error, the charging flag 803 is turned off in step S306, and the corresponding delivery box display unit 1041 is set in a predetermined blinking state in step S307. By visually recognizing the display on the display unit 1041, the resident can confirm that the charging started by the resident has ended in error.

  Note that the display state of the display unit 1041 exemplified in steps S300, S303, and S306 (lighting, blinking, extinguishing, and changing the display color) is merely an example of a display form that uses an LED or the like. When a display means capable of displaying more detailed information is used for the display unit 1041, characters such as “charging is in progress”, “charging has been completed successfully”, “charging has ended in error”, or an appropriate symbol What is necessary is just to display the information regarding the charging service which should be displayed at these steps by display etc.

  In step S305, the usage data related to the charging service received by the resident is recorded (or communicated with the management system 401 via the Internet 400) according to the result of whether the charging process has ended in error or has ended normally. And send usage data). Here, for example, information such as charging start time, end time, required charging time, amount of charge for using the charging service is recorded as usage data (or transmitted to the management system 401) in association with the resident ID information.

  Further, in step S305, a character string such as “charging is completed” or “charging error is completed” is displayed on the display of the intercom 441 along with time information or the like depending on whether charging is normally completed or an error is terminated. . In addition, a charging end message may be output by an alarm sound or a synthesized voice using a speaker of the interphone 441.

  FIG. 6 shows an inquiry control procedure controlled by the delivery box control unit 100. This inquiry control procedure is executed by the delivery box control unit 100 when a predetermined operation (step S112 in FIG. 3) is performed on the operation display unit 151 and an inquiry job regarding the charging process of the electric vehicle is designated. Here, although the procedure which controls the inquiry process which the administrator with the management authority of the delivery box and the charging system of an electric vehicle uses the operation display part 151 is illustrated, a resident (user of the charging system of an electric vehicle) Can use a similar user interface. Modifications in that case will be described as appropriate where necessary.

  Step S401 means that, for example, the administrator (resident) has selected an inquiry regarding “electric vehicle” from the top menu display of the operation display unit 151 using the touch panel of the operation display unit 151.

  When this operation is performed, in step S402, the card reader of the operation display unit 151 presents an ID card, and whether or not the ID information obtained from the ID card is ID information that may permit inquiries regarding the electric vehicle. Determine. Only when this authentication process is successful, the inquiry operation after step S403 is allowed (if the authentication fails, an error process (not shown) is performed). Depending on whether or not the ID card is a card used by a person with management authority, it is selected whether to select a user interface for the administrator or a user interface for the resident (charging system user). That's fine. In the following, an example in which an ID card used by a person with management authority is presented and a user interface for the administrator is selected is shown.

In step S403, a lower management menu than “electric vehicle” in step S401 is displayed. In the menu example of FIG.
・ Resident room number (room number used)
・ Usage data ・ Basic charge settings can be selected. When each menu entry is selected, a display output such as steps S404, S405, and S406 is performed on the operation display unit 151 as shown in the figure.

  In the display of “use room number” in step S404, the room number of the resident who has used the charging system up to now is displayed based on the use data recorded in the RAM 122 or the like. Here, it is displayed that the occupants in each of the rooms 202, 301, and 605 used the charging system.

  In the display of “basic charge setting” in step S405, the current basic charge setting of XX yen per 1H (1 hour) is displayed. Here, the menu interface used by the administrator is shown, and changes related to “basic charge setting” are possible. For example, it may be permitted to use a touch panel to select an amount setting number and input a different amount. By using the basic charge setting amount per charge time, the charge amount can be calculated from the charge time. Note that the user interface used by the user may simply perform processing for displaying the current set amount of the basic charge. Further, the user interface used by the user may further display the user billing data identified by the ID card (for example, the past monthly billing record, the billing schedule for the next month, etc.).

  In the “usage data” display interface in step S406, the charging start time, the charging end time, the room number, the charging, and the like for the past charging job based on the usage data recorded in the RAM 122 or the like in the table format shown in the figure. Display time. It is easier to grasp the display contents by changing the sort order of data according to each item by clicking each item part of charging start time, charging end time, room number, charging time on the touch panel .

  The procedure shown in FIG. 6 is performed via the operation display unit 151 of the delivery box 100, but a similar inquiry can be performed via the intercom 441 of the resident's room. In this case, of course, authentication by the ID card (step S402) is unnecessary, and if other operations are performed through a keyboard or the like provided on the interphone 441, steps S404 to S406 are performed in response to an inquiry. The report can be displayed by the display of the intercom 441 in each room.

  FIG. 7 shows a charging condition setting control procedure controlled by the delivery box control unit 100. Here, too, the procedure for controlling the inquiry process performed by the administrator having the authority to manage the delivery system and the charging system of the electric vehicle using the operation display unit 151 is illustrated as a resident (user of the charging system of the electric vehicle). Can use a similar user interface. Modifications in that case will be described as appropriate where necessary.

  In the procedure of FIG. 7, as in the case of FIG. 6, first, ID card authentication is performed, and if the authentication is successful, menu operations after step S <b> 502 are permitted.

  When the authentication of the manager (user) ID card is successful, in step S502, the sub-menu of “electric vehicle use registration” is entered.

  In the menu operation below “electric vehicle use registration”, various electric vehicle registration and change operations other than those shown in the figure can be performed. Here, for example, a resident can apply for an electric vehicle charging service. An example of an initial setting procedure to be performed when it is performed is shown.

  In the interface in step S503, the charging time can be limited. Here, as an example, the maximum charging time is set to 5 hours, and the maximum charging time allowed for residents who have applied within the range can be set. This maximum charging time can also be set according to the desire of the resident who applied. The maximum charging time can be used, for example, as a condition for terminating charging in step S107 in FIG.

  In the interface in step S504, the room number of the resident who applied for the service can be registered. Here, the room number input on the operation display unit 151 is registered, and in the display immediately after registration, the registered room number is displayed as shown in the figure, the setting content of the maximum charging time set by the interface in step S503, and the like.

  In addition, in the interfaces in steps S503 and S504, the model of the electric vehicle owned by the user can be input and registered.
