  The notification information creation unit 23 extracts notification information, which is information to be transmitted to the mobile phone 70, that is, information such as a charging progress status and a parking fee, from the storage unit 21 and converts it into an e-mail format. Further, the notification information creating unit 23 creates a charging completion notification mail for notifying the mobile phone 70 that charging is completed when the battery is fully charged and charging is completed. By transmitting these e-mails to the mobile phone 70, the charging device management server 20 functions as a notification means for notifying the notification information.

  The warehousing management device 30 is a device installed at the entrance of the parking lot. When the driver of the electric vehicle 3 causes the electric vehicle 3 to enter the parking lot, for example, by issuing a magnetic card to the driver, Carrying in the car 3 As described above, an authentication code different for each magnetic card is recorded on the magnetic card.

  When the warehousing management device 30 issues the magnetic card, for example, based on a clock signal generated by an oscillation circuit (not shown) provided in the warehousing management device 30, the warehousing management device 30 specifies the issue time (the warehousing time) of the magnetic card, The warehousing time and the authentication code are transmitted to the charge management server 50.

  The fee collection device 40 is a device installed at the parking lot exit to collect a parking fee, and includes a magnetic card reading unit and a parking fee display unit. The driver causes the fee collection device 40 to read the magnetic card and pays the parking fee displayed on the display unit to the fee collection device 40 when taking out the electric vehicle 3 from the parking lot. The calculation of the parking fee will be described in detail later.

  When the fee collection device 40 reads the magnetic card, for example, based on a clock signal generated by an oscillation circuit (not shown) provided in the fee collection device 40, the fee collection device 40 identifies the reading time (shipment time) of the magnetic card, The time and the authentication code are transmitted to the charge management server 50.

  The fee management server 50 is a server for calculating a parking fee based on the parking time and managing the parking fee. The fee management server 50 includes a CPU, a RAM, an HDD, etc., and includes a storage unit 51, a parking time measuring unit 52 (parking time) Measuring means) and a charge calculating unit 53 (charge calculating means).

  The storage unit 51 is, for example, the HDD included in the charge management server 50, and the authentication code, the warehousing time, and the charge code transmitted from the charging device management server 20, the warehousing management device 30, and the fee collection device 40 to the fee management server 50. Various types of information such as the correspondence between the delivery time and the authentication code and unit time charges are stored. The unit time fee is a first unit time fee (regular fee) applied to the parking time excluding the charging time, and a unit time fee reduced from the regular fee, and is applied to the charging time. It consists of two unit time charges (discounted charges including free charges).

  The parking time measuring unit 52 measures the parking time of the electric vehicle 3 using the entry time and the exit time. Further, the parking time measuring unit 52 calculates the parking time from the warehousing time as needed based on, for example, a clock signal generated by an oscillation circuit (not shown) included in the fee management server 50.

  The charge calculation unit 53 is a discounted charge that is reduced from the regular charge for the parking charge during the time when the electric vehicle 3 is connected to the charging device 10 and the charging operation is actually performed by the charging device 10 (charging time). To calculate the parking fee. The fee calculation unit 53 transmits the calculated parking fee data to the fee collection device 40. The fee collection device 40 displays the parking fee on a display unit included in the fee collection device 40 based on the received parking fee data. In addition, this display may display only the total amount collected by the fee collection device 40, or in addition to the total amount, displays the total parking time and the charging time, and the parking fee for the charging time and other time The parking fee may be further displayed.

  The correspondence between the operation performed by the driver of the electric vehicle 3 and the operation of each part of the charging system 1 will be described below. The driver receives a magnetic card from the storage management device 30 when the electric vehicle 3 is stored in the parking lot. When the driver parks the electric vehicle 3 in the electric vehicle-dedicated parking space 2 and causes the card reader 15 of the charging device 10 to read the magnetic card, the authentication code is transmitted to the charging device management server 20 and further charged. The data is transferred from the device management server 20 to the charge management server 50.

  By the way, in the charging system 1, the discounted unit time fee is applied to the parking fee during the charging time. In order for the driver to receive the discount, it goes without saying that between the issuance of the magnetic card at the time of receipt by the warehousing management device 30 and the reading of the magnetic card at the time of delivery by the toll collection device 40. It is necessary to make the charging device 10 read the magnetic card.

  The driver starts charging by connecting the charging cable 14 to the charging socket of the electric vehicle 3, and reads the two-dimensional information code 80 using the mobile phone 70 before leaving the charging device 10, to the URL. to access. Since the URL is displayed as the two-dimensional information code 80, the driver can access the URL without troublesome character input.

  For example, an e-mail address is displayed on the Web page connected by accessing the URL, and the driver transmits a blank e-mail to the e-mail address using, for example, the mobile phone 70. The empty mail is transmitted to the charging apparatus management server 20 via the Internet 60, and the mail address of the mobile phone 70 is registered in the charging apparatus management server 20.

  By performing this registration operation, the driver can receive charging information such as the end of charging of the battery of the electric vehicle 3 and the progress of charging by e-mail.

  The e-mail address displayed on the Web page is preferably changed every time the URL is accessed. For example, it is assumed that another driver who has used the charging device 10 in the past erroneously sent a blank email to the email address displayed on the Web page during a registration operation. In this case, since the e-mail address is already invalid, the charging information relating to the driver who is using the charging device 10 is not transmitted by e-mail. That is, the e-mail address displayed on the Web page is changed every time the URL is accessed, thereby preventing charging information relating to the driver using the charging device 10 from leaking to a third party. .

  By setting the transmission destination of the information to the mobile phone 70, it is not necessary to prepare a dedicated mobile terminal, so that the construction cost of the billing system can be reduced. In addition, the communication cost can be reduced by notifying the mobile phone 70 of the information as voice guidance but as an e-mail.

  The registration operation enables the driver to know the progress of charging of the battery by the e-mail, so that the time until the end of charging of the battery is estimated and the time until the end of charging is effective. Can be used for

  When the driver registers the URL in the mobile phone 70 during the registration operation, and the driver accesses the URL and displays the web page, the progress of charging, etc. You may make it display on a web page. As described above, since the mobile phone 70 and the charging device management server 20 can communicate bidirectionally, the driver can know progress information of the battery charging at any time. The convenience for the person is further improved.

  The calculation of the parking fee by the fee calculating unit 53 will be described in detail with reference to FIG. FIG. 2 is a diagram illustrating a time chart from the entry to the exit of the electric vehicle. The total parking time T includes a first period t1 corresponding to the charging time and a second period t2 corresponding to the time excluding the charging time.

  Billing starts when the warehousing management device 30 issues the magnetic card during the warehousing procedure. Since it is not the charging time from the start of charging to the start of charging of the electric vehicle 3, it is the second period t2. When charging of the electric vehicle 3 is started, the first period t1 starts, and when the battery of the electric vehicle 3 reaches full charge or when the driver removes the charging cable 14 from the charging socket of the electric vehicle 3 Thus, the first period t1 ends. The period from the end of the first period t1 to the end of billing in the shipping process in the fee collection device 40 is again the second period t2.

  The fee calculation unit 53 uses a unit time fee that is reduced based on the first unit time fee for the parking fee in the first period t1, and is reduced from the first unit time fee for the parking fee in the second period t2. The parking fee is calculated based on a certain second unit time fee.

  The first unit time charge and / or the second unit time charge can be input / changed from an input device 54 (setting means) such as a keyboard connected to the charge management server 50. In this case, for example, when changing the fee structure of the time-rental parking lot, the parking fee of the electric vehicle can be set flexibly.

  In addition, a plurality of the second unit time charges are stored in the storage unit 51 in advance, and the charge calculation unit 53 determines one unit from the plurality of unit time charges based on predetermined information including at least day information or time information. The hourly fee may be automatically selected, and the parking fee may be calculated based on the selected unit time fee. In this case, the parking fee of the electric vehicle 3 can be set according to the parking space utilization rate that varies depending on the time of day or day of the week.

  Based on FIG. 3, the process performed in the charging system 1 during the period from entry to exit of the electric vehicle 3 will be described over time. FIG. 3 is a flowchart illustrating processing performed in the charging system 1 during the period from entry to exit of the electric vehicle 3.

When the warehousing management device 30 issues the magnetic card as a warehousing procedure, the warehousing time and the authentication code, which are warehousing information, are transmitted to the fee management server 50 (step S1). When the fee management server 50 receives the warehousing information, the parking time measuring unit 52 starts measuring the parking time (step S2).

  The driver who has completed the warehousing procedure parks the electric vehicle 3 in the electric vehicle-dedicated parking space 2. At this time, the driver causes the card reading unit 15 of the charging device 10 to read the magnetic card and accesses the URL assigned to the charging device 10 to register the mail address of the mobile phone 70. In this registration work, the charging device management server 20 receives an empty mail transmitted from the mobile phone 70, and the registration receiving unit 22 recharges the mail address of the mobile phone 70 transmitted to the charging device management server 20 by the registration operation. The device 10 is associated and the correspondence is stored in the storage unit 21 (step S3).

  The driver who has finished the registration work connects the charging cable 14 of the charging device 10 installed in the electric vehicle-dedicated parking space 2 to the charging socket. Thereby, the charging state detection unit 12 starts communication for exchanging information such as the charging state of the battery included in the electric vehicle 3 with the electric vehicle 3, and based on the information received by the charging state detection unit 12. The charging unit 11 starts charging the battery (step S4).

  When charging is started, the charging time measuring unit 13 starts measuring charging time (step S5). While the charging state of the charging unit 11 continues, the charging time measuring unit 13 continues to measure the charging time (NO in step S6). When the charging state of charging unit 11 ends (YES in step S6), charging time measuring unit 13 ends the measurement of the charging time (step S7).

  Furthermore, when the charging state of the charging unit 11 ends, the charging device 10 transmits information such as a charging end time, a charging time, and a charging electric capacity to the charging device management server 20 as a charging end notification (step S8). At this time, the notification information creating unit 23 creates a charging completion notification mail for notifying the mobile phone 70 that the charging has been completed, and transmits it to the mobile phone 70 (step S9).

  The driver who knows the end of charging through the charging completion notification e-mail drives the electric vehicle 3 toward the parking lot exit and causes the fee collection device 40 to read the magnetic card in order to take out the electric vehicle 3. Will do. When the fee collection device 40 reads the magnetic card, the fee collection device 40 transmits the reading time (shipping time) of the magnetic card as the shipping information and the authentication code to the fee management server 50 (step S10).

  When the fee management server 50 receives the delivery information, the parking time measuring unit 52 ends the parking time measurement (step S11). Then, the charge calculation unit 53 calculates the parking fee with a discount fee reduced from the regular fee for the parking fee for the charging time, and transmits the calculated parking fee data to the fee collection device 40. (Step S12). The fee collection device 40 displays the parking fee on a display unit provided in the fee collection device 40 based on the received parking fee data, and the driver pays the parking fee to the fee collection device 40 and performs a delivery process. Is completed.

  As described above, according to the above-described embodiment, the second unit time fee in which only the parking fee for the time for charging the electric vehicle 3 in the parking time is reduced from the predetermined first unit time fee. The charge is calculated at the other time, and the charge is calculated at the first unit time charge at other times. That is, if the electric vehicle-dedicated parking space 2 is unnecessarily occupied even after the charging is completed, the driver of the electric vehicle 3 pays an expensive parking fee. Therefore, an incentive for the driver to quickly move the electric vehicle 3 from the electric vehicle-dedicated parking space 2 including the charging device 10 is activated, and the utilization rate of the charging device 10 can be improved. Therefore, the charging facilities for electric vehicles can be minimized, and the capital investment cost can be reduced. As a result, the effect of promoting the popularization of charging facilities for electric vehicles can be expected.
