Description

  The present invention relates to a vehicle charge management system for charging a battery provided in a vehicle during parking.

  In order to popularize electric vehicles and plug-in hybrid vehicles, it is said that maintenance of parking lots equipped with charging facilities is indispensable. And in large-scale parking lots and general-time rental parking lots such as shopping centers and condominiums, unlike uninhabited parking lots, unspecified vehicles are parked at unspecified parking positions, so there is a charging fee charging system. It becomes a problem.

  With respect to such a problem, in the invention of Patent Document 1, when an electric vehicle enters a parking area of a parking lot, a vehicle stop is activated by a vehicle sensor, and after charging by a charging terminal provided at each charging position, It has proposed a billing system in which parking is released and parking can be released after paying the parking fee and the charging fee.

  However, such a billing system requires a car stop device for each parking position, and there is a problem that a very large facility cost is required in a parking lot with a large number of parked vehicles.

  In order to avoid placing a large number of car stop devices in this way, it is conceivable to collect charging charges at the entrance and exit of the parking lot, but in order to grasp which car consumed how much power to charge It is necessary to grasp which vehicle used the charging terminal provided for each parking position. For this reason, after all, a user authentication device such as an IC card reader is provided for each parking position, and the terminal for charging at the parking position can be used on condition that user authentication has been performed. Must adopt a system that charges the user for charging.

However, in such a system that requires an IC card reader for each parking position, the facility cost of the parking lot becomes extremely high, which is a major obstacle in constructing a charging system for a parked vehicle.
JP-A-6-318288

  The present invention has been completed based on the circumstances as described above, and provides a vehicle charge management system capable of realizing a charge system for the charge fee at a low cost while enabling charging in a parking lot. With the goal.

  The vehicle charge management system according to the present invention includes a charging terminal provided at a parking position for parking a vehicle in a parking lot, and a charging terminal identification provided corresponding to these charging terminals to identify them. A sign section indicating information, a distribution board connected to the charging terminal by a power supply line and individually controlling power supply to the charging terminal, and a usage measurement for measuring the usage for each charging terminal And the power distribution permission signal for identifying the charging terminal based on the charging terminal identification information transmitted from the wireless information terminal device and allowing the power feeding to the charging terminal. A charging management server that controls the panel and records the usage amount of the charging terminal for each user specified by identifying the user by terminal identification information sent from the wireless information terminal device. That.

  The operation of the charge management system configured as described above is as follows. A driver parks at an arbitrary parking position in a parking lot, and first makes a vehicle chargeable using a charging terminal provided there. Next, the driver or passenger uses, for example, a wireless information terminal device such as his mobile phone, and transmits the charging terminal identification information of the sign corresponding to the charging terminal to be used to the charging management server. . Then, the charge management server identifies the charging terminal based on the charging terminal identification information transmitted from the wireless information terminal device, and supplies a power supply permission signal for allowing power supply to the charging terminal. And charging at the charging terminal is allowed.

  On the other hand, when communicating with the wireless information terminal device, the charge management server side can acquire terminal identification information for identifying a communication partner, so that the charge management server uses the charging terminal using it. Can be identified. Alternatively, the wireless information terminal device allows the user to transmit a user ID and the like to the charge management server.

  And since the usage-amount measuring means acquires charging information such as the amount of power used and the usage time in the charging terminal, for example, the charging information for each user can be recorded by associating and recording the charging information and the charging terminal identification information. It is possible to charge based on the usage of the terminal.

  Note that it is convenient that the above-described charge management server has a WEB server function because it is easy for a user to input information related to vehicle charging such as a charging time and a charging end time. Furthermore, if the charge management server is configured to include a user database using the user identification information as a key, a plurality of users can be managed using a single wireless communication line.

  Further, when a mobile phone terminal with a camera is used as the wireless information terminal device, a bar code sheet can be used as the indicator, and in this case, the URL for accessing the WEB server is used as the bar code. By recording, the usability will be improved.

  In addition, in a vehicle adopting a plug-in charging system, as a charging terminal, an outlet is provided on a support column disposed at a parking position, and a sign section that describes charging terminal identification information (parking position number, etc.) Since it suffices to provide it in the column, the equipment for each parking position becomes extremely simple.

  According to the present invention, as a facility on the parking lot side, a charging terminal and a sign unit are installed at each parking position, and a charging management server is installed at the management room side. Compared to a conventional system that required the provision of a user authentication device, it can be constructed at a significantly lower cost.

  An embodiment in which the present invention is applied to a shopping center or a parking lot of an apartment house will be described with reference to FIGS.

  In the parking lot, parking positions of a plurality of vehicles are divided and provided, and charging posts 10 corresponding to the column portions are erected corresponding to the parking positions. The charging post 10 is made of, for example, a stainless steel pipe and has a cylindrical shape with the upper end closed, and an outlet 11 corresponding to a charging terminal is embedded in the peripheral wall surface. On the outer peripheral surface of the charging post 10, a bar code sheet 12 corresponding to the mark portion is attached under the outlet 11.

  The barcode sheet 12 is configured by, for example, a QR code, and records information indicating URL information of a predetermined WEB site, a parking lot name, and a parking position thereof. In this embodiment, since the parking position and the outlet 11 are in a one-to-one correspondence, the content of the barcode sheet 12 corresponds to charging terminal identification information for specifying the charging terminal.

  Each outlet 11 is connected to a distribution board 14 through a power supply line 13, and the distribution board 14 is supplied with AC power from a power receiving facility 15 in a parking lot. The distribution board 14 is provided with a relay 16 corresponding to each outlet 11, and the power supply to each outlet 11 can be individually controlled by this relay 16. Each relay 16 is controlled by a relay control circuit 17, and the relay control circuit 17 is controlled by a charge management server 18.

  The main functions of the charge management program executed by the charge management server 18 are as shown in FIG. 2 and FIG. 3, and are basically a WEB server function for a mobile phone, a user database function, and an outlet use database function. And a relay control function.

  Next, the operation of the charge management system of this embodiment will be described. For example, it is assumed that a vehicle EV (plug-in charge type electric vehicle) entering a shopping center parking lot is parked at an arbitrary parking position. When the driver wants to charge the vehicle EV, the charging plug P provided in the vehicle is inserted into the outlet 11 of the charging post 10 so that the vehicle can be charged. At this stage, the corresponding relay 16 of the distribution board 14 is not closed, and power is not supplied to the outlet 11.

  Next, the driver or the passenger activates the barcode photographing function of the cellular phone terminal 20 and photographs the barcode sheet 12 under the outlet 11 into which the charging plug P is inserted by the camera built in the cellular phone. Then, the mobile phone terminal 20 reads the URL of the WEB site for parking lot management, the parking lot name, and the parking position information from the barcode, and establishes a wireless communication line with the base station 21 based on the information. Then, it is connected to the Internet line and guided to the WEB site provided for each outlet by the browser of the mobile phone terminal 20 (step S101). This WEB site is provided by the WEB server function of the charge management server 18.

  When the mobile phone terminal 20 is connected to the charge management server 18, a screen requesting input of a user ID and password is transmitted from the charge management server 18 to the mobile phone terminal 20 and displayed on the screen. When the user inputs a user ID and password in response to the request (step S102), the user is authenticated by searching whether or not the user database is already registered (steps S103 and S104). If the user database is not registered in advance, a display for prompting user registration is displayed on the screen of the mobile phone terminal 20. This user authentication is provided by a user database function of the charge management server 18, and the user database includes fields such as a user ID, a user name, an address, a charge billing destination, a payment method, and the like. It is constructed using a user ID as information as a key.

  When the user authentication is successful, the charge management server 18 transmits a screen requesting the user to input the usage time, and in response, the user inputs the length of time for which the electric vehicle EV is desired to be charged as the usage time. (Step S105).

  Next, a screen requesting selection of a charging method is transmitted from the charge management server 18 (step S106). There are three types of charging methods: “immediate charging” for immediately starting charging, “starting time reservation” for reserving the charging start time, and “completion time reservation” for reserving the charging completion time. When “start time reservation” is selected, a start time input screen appears. When the start time is input here (step S107), the timer enters a standby state until that time (step S108). When “reservation of completion time” is selected, an input screen for completion reservation time appears, and when the completion time desired to be charged is input (step S109), the charge management server 18 Selects the time zone with the lightest load for the power receiving equipment 15 in consideration of the usage status and reservation status of other outlets and the time required for charging the vehicle, and sets the start time in that time zone as the start time of charging. (Step S110), and a standby state is set by the timer until the start time (Step S111).

  When the above-mentioned “immediate charging” is selected, the charge management server 18 immediately sets the time together with the user ID when the “start time reservation” or “completion time reservation” is selected. It records in the outlet use database (step S112), and simultaneously outputs a power feed permission signal to the distribution board 14 via the relay control circuit 17 (step S113). Then, the relay control circuit 17 closes the corresponding relay 16 of the distribution board 14 to supply power to the specified outlet 11. As a result, charging of the electric vehicle EV is started, and the charge management server 18 calculates an end time (step 114), and proceeds to a charge end process (step S200).

  The specific contents of the charge termination process are as shown in FIG. That is, on the condition that a charge end notification is received from the vehicle being charged (step S201) or the end time is reached (step S202), the current time is recorded in the outlet use database together with the user ID ( In step S203, simultaneously, the output of the power feed permission signal to the distribution board 14 is stopped via the relay control circuit 17 (step S204). Then, the usage time of the charging power through the outlet 11 is obtained by subtracting the start time from the end time (step S205), and this is recorded in the outlet use database together with the user ID (step S206), and the process ends. The outlet usage database includes fields of outlet identification information (charging terminal identification information), user ID of the user who performed charging, start time (including date and time), end time (same), and usage time. In this embodiment, since the usage amount of the outlet 11 is recorded as the usage time (step S205), the charge management server 18 also functions as a usage amount measuring means for measuring the usage amount of the outlet 11.

  According to this embodiment, the usage time (charging time) of the outlet 11 for each outlet 11 (for each parking position) is recorded in the outlet usage database of the charging management server 18 together with the user ID. Therefore, by accessing the outlet usage database and the user database, it is possible to calculate and charge the usage fee of the outlet 11 for each user.

In this embodiment, as a fixed facility on the parking lot side, it is only necessary to install the charging post 10 at each parking position and connect it to the distribution board 14. Since the charging post 10 is an extremely simple one having only the outlet 11 and the barcode sheet 12, it can be mass-produced at a very low cost and has almost no maintenance burden. And in this embodiment, since the mobile phone terminal which the driver | operator and passenger of a vehicle have extensively can use effectively as an apparatus for performing user authentication, for user authentication, such as an IC card reader There is no need to prepare expensive and complicated electronic equipment on the parking lot side. Of course, the charge management server 18 is required in the parking lot, but this can use an inexpensive general-purpose personal computer or general-purpose server, and the program for the charge management server 18 should be used universally for many parking lots. Therefore, the introduction cost can be kept low. Thus, according to the present embodiment, the construction cost of the charge management system in the parking lot can be greatly reduced.
In particular, in the present embodiment, when the user selects “completion of completion time”, the charge management server 18 receives power in consideration of the use status and reservation status of other outlets and the time required for charging the vehicle. The time zone with the lightest load for the facility 15 is selected, and the start time in that time zone is set as the charging start time (step S110). This makes it possible to control the number of vehicles that are in a charged state simultaneously as compared to a system that starts charging an electric vehicle immediately if there is a request, so the power receiving equipment 15 has a small capacity for the number of parked vehicles. It becomes possible to respond. As a result, since the capital investment cost for the parking lot with a charging function can be kept low, there is a great advantage also for an apartment house manager such as a condominium.

  Furthermore, in the present embodiment, since the charging condition desired by the user and the charging condition such as the charging start time or the charging end time can be input using the WEB server function of the charge management server 18, it is complicated. Even simple condition settings can be set freely and are easy to use. In addition, since the bar code shooting function of the mobile phone terminal 20 is used to record the URL information of the parking lot management WEB server in the QR bar code, the WEB access becomes extremely simple. Furthermore, since the user database function is provided, there is an effect that a plurality of registered users can be charged for each user.

<Other embodiments>
The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  (1) In this embodiment, the usage amount of the charging terminal (outlet 11) is measured as the usage time, and is recorded and calculated in the charging management server 18. However, the present invention is not limited to this. A measuring device such as a wattmeter or an ammeter is installed on the power supply line to measure the amount of power used for charging for each outlet 11 as the usage amount of the charging terminal, and the measured power amount (usage amount) You may charge accordingly. Even in this case, a measuring device such as a wattmeter can be intensively provided on the distribution board 14, so that it is not necessary to provide a measuring device at each charging post or charging terminal portion, and the distribution board It can be installed at low cost by installing only the part. In addition, the expansion work for adding a charging terminal is extremely simple, and it is possible to reduce the construction cost and the equipment cost as a whole.

  (2) In the above-described embodiment, the charging terminal is configured by the outlet 11 corresponding to the plug-in charging method. However, the present invention is not limited thereto, and the power supply connector on the charging device side is connected to the power receiving connector provided in the vehicle. It is good also as a structure. Further, it is not always necessary to adopt a contact type power supply method, and for example, an electromagnetic induction type non-contact type power supply method may be used.

  (3) In the above embodiment, an example in which a mobile phone terminal is used as a wireless information terminal device has been shown. However, the present invention is not limited to this, and even in a PDA or car navigation system having an Internet connection function through a wireless communication line, It can be configured similarly. In addition, the terminal identification information for charging and the user identification information may be directly input to the charging control server via a wireless communication line, without necessarily connecting to the WEB server via the Internet. Further, the terminal identification information for charging is not limited to the one recorded in the barcode, but may be simply a parking position number, and the user identification information uses the identification information itself of the terminal apparatus that the wireless information terminal apparatus originally has. May be.

(4) In the above embodiment, the charging terminal is specified based on the information from the user's wireless information terminal device, and the charging permission signal for the charging management server to supply power to the charging terminal on the distribution board is provided. It was set as the structure to output. However, advertisement viewing by the wireless information terminal device may be added as a condition for outputting the power supply permission signal as follows.
That is, for example, when the user photographs the barcode sheet 12 attached to the charging post 10 with the mobile phone terminal 20 and connects to the WEB site, the position of the charging post 10 is specified by the information recorded on the barcode sheet 12. At the same time, an advertisement screen of a specific store or shopping street is displayed on the display of the user's mobile phone terminal 20. When it is determined that the user has watched the screen for a certain period of time, power is supplied to the outlet 11 corresponding to the charging post 10 so that the charging is possible. In the case of such a system, it is possible to cover part or all of the facility and operating expenses (electricity charges, etc.) of the parking charging system using the advertising fee to be received from the publisher of the advertisement as a source. The introduction cost of the system can be greatly reduced, and the introduction becomes easy. In addition, since free parking and free charging are possible, there are merits for the vehicle user, and there are also merits for shops and shopping streets, etc., because an increase in the number of visitors expecting this is expected. In the case of the above system, the parking / charging fee is not necessarily free, and the fee may be discounted. Also, when shopping at a specific store or shopping street, for example, by taking a barcode received at that store / shopping street with a mobile phone terminal, parking and charging fees can be discounted and made free. May be.
