FIG. 4 is a schematic configuration diagram showing an embodiment of use acceptance means of an electric vehicle charging system for parking lots.

  In facilities where charging facilities for multiple electric vehicles are installed, for example, large stores, hotel parking lots and multi-storey parking lots of apartment buildings are assumed. ) And the required charging time (desired charging time) of each parked vehicle do not necessarily match, so it is not necessary to start charging at the same time as parking starts. Therefore, the present invention provides a plurality of charge patterns in advance (for example, pattern 1: immediate charge (full tank), pattern 2: specified time charge (charge time of 30 minutes, 1 hour, etc. can be selected), pattern 3: delivery In the electric vehicle charging system for parking lots, which is prepared by selecting a charge pattern desired by the user at the time of warehousing, etc., with time-specified charging (XX month XX day XX hour XX minutes scheduled to be released) is there.

  Currently, there are several types of parking lots where multiple cars can be parked. For example, parking lots that are mainly used for exclusive use by residents of condominiums, such as condominium parking lots, large stores such as department stores, and parking lots of hotels and hotel users. There are things that we are thinking about, public parking lots for general users, and those where they are mixed. In any case, as a future trend, the number of electric vehicle users will increase, so there is no doubt that parking facilities equipped with charging facilities for electric vehicles will also be created in these parking lots.

  On the other hand, the operating expenses of these parking lots are basically collected from each user as a parking lot usage fee. And in Japan, no power selling activities other than electric power companies are allowed, so even if you manage a parking lot equipped with a charging facility in the future, There is a problem in collecting the electricity charges. In addition, the electricity cost for a full charge of a car is not so large even if it is a quick charge. Then, it is necessary to charge the parking fee of the charged car as a usage fee for the parking space where the charging facility is installed. As a result, even if it is a parking lot with a slightly higher usage fee, if it is a parking lot with a highly convenient charging facility, the number of users using the parking lot can be increased, and an increase is expected in the future. The advantage of being able to call a user of an electric vehicle as a customer at his / her own store comes out.

  When managing a parking lot equipped with a charging facility as described above, it will be managed as a car that will be parked in a parking space with a charging facility at the time of entering or leaving ("parked car that needs to be charged after parking") ) Or a car that is scheduled to park in a normal parking space (or a parked car).

  One possible solution to this is a membership system (membership system such as a monthly contract or an annual contract) that allows users who park in a parking space with a charging facility to register as a member in advance. Therefore, it is conceivable that the user registers personal information as a member in advance to the parking lot electric vehicle charging system and passes the member parking lot card (for electric vehicle). It is also possible to register personal information such as a mobile mail address if necessary. Such a pre-member registration system may not be suitable for parking lots with strong publicity. In that case, at the time of warehousing, the intention of using the parking space with the charging facility is confirmed to the user from the usage reception means of the general management device (local management device) installed near the warehousing gate, and the charging facility is used. For a user who wishes, if a vacant charging facility can be used, a method of issuing a predetermined charging parking card and proceeding to the next step can be adopted.

  However, in the present invention, the membership system registration method and the selection method for determining whether or not the warehousing vehicle can be received at the time of warehousing are not intended as direct inventions. Therefore, in the following description of specific examples, the description will focus on the use of a membership-based electric vehicle charging system for parking lots, but the present invention is not limited thereto.

  Hereinafter, the system configuration of the electric vehicle charging system for a parking lot according to the present invention will be described with reference to FIG.

[Use acceptance means (IC card reader / operation display)]
Here, an electric vehicle charging system for a parking lot with a membership system will be described as an example. In this case, each user must have a member IC card 400 or the like in which member registration is completed and personal information is recorded (of course, the electric vehicle charging system for parking lots of the present invention needs to be a membership system). In that case, the present invention can be applied by issuing an appropriate parking lot use card). Each user causes the IC card reading unit 270 serving as a use receiving unit to read the IC card 400 for authenticating the user, and gives a charge pattern instruction to the local management device 200. At that time, the user's mobile mail address can be registered. If you have a membership system, you should register your mobile mail address in advance. In addition, it is possible to register after the fact that the mobile phone 500 reads the two-dimensional bar code displayed on the use accepting means 270 arranged in the vicinity of the local management device 200. In the embodiment of FIG. 1, the IC card reading unit controlled by the local management device 200 is shown as a device 270 integrated with the operation display unit, but, of course, each may be configured separately. When the desired reservation is completed, the operation display unit 271 displays the reservation contents.

  FIG. 4 shows the detailed configuration of this usage acceptance means. The use accepting unit 270 is provided with a display 271 for various displays. In FIG. 4, three charging types are displayed. These charge types are selected by pressing a charge type selection switch 272. Of course, the charge type selection switch 272 may be a touch panel type. In addition, a numeric keypad 273 is provided and used for inputting a shipping time and the like. In the case of a membership system, a membership card is inserted into the card insertion slot 274 and data is read. When it is desired to send and receive information through a mobile phone, a label 275 described with an address two-dimensional barcode accessible to the electric vehicle charging system for parking is read with the mobile phone. The use accepting unit 270 is connected to the local management device 200, and the local management device 200 includes a power supply control unit 201, a reservation management control unit 202, a charging / settlement calculation unit 203, and an information communication control unit 204. ing. In the present invention, the “mobile phone” does not mean that the mobile phone is limited to only a mobile phone, and it does not depart from the idea of the present invention as long as it is a portable information terminal device.

  The charging method by the electric vehicle charging system for parking lots according to the present invention will be described in the order of circled numbers in FIG. That is, the user A possesses the membership card (IC card or the like) 400 and the mobile phone 500, and (1) performs an acceptance operation to the electric vehicle charging system for parking lot. At that time, it is possible to register personal information such as an address using his / her mobile phone. (2) Next, a desired charging pattern is instructed. (3) If charging with a desired charging pattern is possible, it is accepted and a charging instruction is issued according to the pattern. (4) When charging is completed, billing / settlement is calculated and processed. (5) If the mobile mail address is registered, a charging completion mail for the mobile mail is transmitted. (6) It is possible to change the reserved charging pattern from the mobile phone.

  Hereinafter, the operation method of the electric vehicle charging system for parking lots according to the present invention will be described with reference to FIGS.

[Member information]
Explain the membership system. A user obtains an IC card or the like for authenticating an individual as a member in advance for membership registration. If this is a condominium or the like, it can be shared with a use card of a delivery box installed in a common space. Moreover, if it is a department store, a store, etc., it is also possible to make it common with a store's own member system. In the case of the electric vehicle charging system for parking lots according to the present invention, what is registered in advance as member information can register the charging voltage of the electric vehicle owned, the time required for normal full charging, and the like. In addition, more detailed services can be achieved by registering the model and registration number of the car you own.

  It is preferable to set the mobile mail address of the user corresponding to the IC card in advance at the time of member information registration or initial setting. Thereby, various communications (charging completion report etc.) can be made to the user from the electric vehicle charging system for parking lot according to the present invention, and the user can charge the electric vehicle for parking lot using a mobile phone. It is also possible to change the charge pattern reserved by connecting to the system.

〔Initial setting〕
When the user first uses the electric vehicle charging system 100 for parking lot according to the present invention, the user registers initial setting information of personal data in advance with respect to the local management device 200 as the overall management means. Of course, this initial setting information can also be registered in advance using a personal computer or a mobile phone. Such initial setting is not necessarily required in the present invention, and is difficult to implement in a public parking lot. However, by performing such initial settings, it is possible to provide a more detailed service in accordance with individual requests.

[Charging pattern]
In the electric vehicle charging system and the charging method for a parking lot according to the present invention, the user is provided with a plurality of charging patterns prepared according to his / her car status (current charging status, future drive plan, etc.) at the time of storage. Select one of the charging patterns that you want from and enter it.
The plurality of charging patterns include, for example, (1) immediate charging (full tank), (2) specified time charging (15 minutes, 30 minutes, etc.), and (3) delivery specified charging (scheduled completion time specified charging). It is possible to select and input a desired charge pattern from among the charge patterns. In this case, it is also possible to design a charging pattern desired by the user by combining charging speeds such as fast charging, medium speed charging, or normal charging.

[Price pattern]
In the electric vehicle charging system 100 for parking lot according to the present invention, it is also possible to prepare a pattern of charge setting (night power use etc.) according to a time zone such as use date and time as calendar information.

[Selection of charging pattern at warehousing]
In the case of the membership system, the user has registered as a member in advance, and the local management device 200 of the electric vehicle charging system 100 for parking lot is replaced by the IC card 400 or the like at the warehousing step S10 in FIG. (IC card reader incorporated in use accepting means 270). If it is not a membership system, the control device installed in the vicinity of the local management device 200 (using the usage acceptance unit 270 in FIG. 4) inquires the user whether or not the parking space with the charging facility is desired (control of the usage acceptance unit 270). Only when it is determined that the local management device 200 can be used (by button operation of the device), the use of the parking space with the charging facility is permitted. So far, it is preferable to carry out before or when entering the parking lot. Of course, it is possible to perform the above operation near a parking space with a charging facility after warehousing, but in this case, the electric vehicle charging system 100 for parking at the time of warehousing has a free space in the parking space with a charging facility that can be charged. It is necessary to be able to confirm that there is at the time of goods receipt.

  Next, the user selects S40 a charging pattern desired by the user from among a plurality of prepared charging patterns in the warehousing permission determination step S20. The selected desired charging pattern is determined by the local management device 200 that controls the electric vehicle charging system 100 for parking lots (S50). The local management device 200 manages the charge reservation status of the electric vehicle charging system 100 for the parking lot, issues a charge instruction within the power capacity range, and if the desired charge pattern can be accepted, Reservation is accepted (S70). When the setting of the charging pattern desired by the user is completed, the reservation completion information is displayed on the display device 271 of the usage receiving means 270, and the reserved charging pattern information is printed out on a parking card or the like, or is displayed on the user's mobile phone. In response, the information is transmitted (S80).

[Charging pattern resetting instructions]
When the charging pattern desired by the user cannot be received (S50), the local management device 200 displays the charging pattern that can be received on the operation display unit 271 and the like, and prompts the user to reset (S60). For example, although there is a vacant parking space with a charging facility, a quick 30-minute charge is impossible from the viewpoint of power capacity, but a normal charge of 1 hour is possible.

[Charging pattern reservation completed]
When the local management device 200 determines that the charging pattern desired by the user is an acceptable charging pattern, the charging reservation is accepted (S70). When the reservation is accepted, the reservation content and the completion of the reservation are displayed on the operation display unit, and the result can be printed out on a parking card or the like (S80). If the e-mail address is registered under the membership system or the like, it is also possible to send the reservation contents by e-mail to the e-mail address (S80).

  After confirming the completion of the reservation, the user parks the automobile in the parking space and connects to the charging facility (the quick charging device 210, the normal charging device 211, or the power outlet 220). The parking space to be used by the user can be designated by the local management device 200 as the number of the parking space, and after the parking space with the charging facility is parked, the reading installed in the parking space. It is also possible to display on the local management device 200 charging equipment (rapid charging device 210, normal charging device 211 or power outlet 220) to be supplied with power by holding an IC card or the like over the device.

For a user who has input a scheduled leaving time with a sufficient charging time as a charging pattern at the time of warehousing, some profits such as a discount on the usage fee or point acquisition can be prepared.
If the mobile mail address of the user is registered, the reservation content is notified by mobile mail together with the profit information (S80).

[Charging instructions and charging control]
The local management device 200 determines whether or not it is the charging start time according to the charging reservation status for each charging facility (rapid charging device 210, normal charging device 211 or power outlet 220) (S90), and the charging that has reached the charging start time. The supply of power to the facility is started and controlled (S100, S110). In addition, power is monitored by each of the supplied wattmeters 230, 230, and 230 so as not to exceed the capacity.

[Communication completion]
When charging of the parked vehicle is completed (full charging completed, time charging completed, etc.) (S120), the local management device 200 cuts off the power supply to the charging facility or the power outlet 220. At the same time, when the mobile mail address of the user is registered, the completion of charging is notified by mobile mail (S140). In addition, when the charging is not completed by the delivery time, the mobile mail is notified (the same processing can be performed when there is a possibility that the desired charging may not be completed).

[Change charging pattern]
Further, the user can instruct to change the charging pattern having a different charge system from the mobile phone 500 or the like via the Internet (S150). The local management device 100 can accept a charge pattern change request from a user at any time via the mobile phone 500 or the like by the Internet function. The local management device 100 that has received the charge pattern change instruction determines whether or not the changed charge pattern is an acceptable pattern. When a charge pattern to be selected is instructed, a reservation change is accepted.

[Billing / Payment]
When the user leaves the store, the local management device 200 provides user information, use date and time, use time, and information on power consumption to a billing / settlement system (not shown), and calculates a parking lot use fee ( S130). At the same time, some profit calculations such as discounts on usage fees and point acquisition are also performed. This step may be executed before the step (S140) of notifying the completion of charging by mobile mail, or may be executed after S140. If it is executed before, it is possible to convey information about the usage fee when notifying the completion of charging by mobile mail.

[Learning function]
A user who feels that the above warehousing operation is troublesome can also be considered. In particular, in a parking lot where a user such as an apartment is specified, the daily charging pattern is often the same. For such a case, it is possible to provide a learning function for each user ID with respect to the scheduled delivery time of each user in the membership system, and the daily charging pattern for the user by the learning function If there is no change instruction, the charging pattern stored at the time of warehousing can be selected. When charging is desired with a charging pattern different from the daily pattern, it is possible to charge with a desired charging pattern by performing normal input.

〔Other features〕
When a parking lot usage fee system is constructed by such a method, the usage fee varies depending on the user, and it is expected that it will take time to go out. Therefore, in the case of an electric vehicle (it is possible even in cases other than electric vehicles), the exit gate is configured to open the gate by omitting the fee payment operation like the ETC gate, and the charge is settled by card. Is possible.

  In the present invention, in the step of reserving charging, it is possible to select a desired charging pattern using a communication function of a mobile phone or a car navigation system installed in a car. In that case, it is desirable to have a membership system in which the ID information of users such as mobile phones is registered in advance.
