  In other words, the power supply installation manager and the user are in a separately concluded contract. In addition, the power supply installation manager and the power supply service provider have a power supply service consignment contract. As a result, the user has a relationship indirectly concluded with the power supply service provider through the power supply installation manager. Further, the power supply service provider and the settlement agent have a relationship for consigning usage fee billing. The payment agent charges the user a usage fee, and the user pays the usage fee to the payment agent.

  A power supply charging process (see FIG. 1) constituting the power supply charging system for an electric vehicle in this embodiment will be specifically described below with reference to FIGS.

  First, in the power supply request (STEP 1) shown in FIG. 3, the user 10 captures the QR code 21 attached to the power supply apparatus 20 with the mobile phone 11, thereby allowing the power supply service provider to connect via the communication network 30. The power supply server 40 is accessed (STEP 1-1). By the access from the user 10 to the power supply server 40, the power supply server 40 specifies the power supply device 20 that the user 10 requests to supply power. In the power supply server 40, user information for specifying the user 10 and apparatus information for specifying the power supply apparatus 20 are stored in advance as a database (not shown). Here, the communication network 30 includes a network such as a mobile phone network and the Internet.

Can be selected and used, and generally inexpensive late-night power can be selected and used.

  In the power supply start (STEP 4) shown in FIG. 6, the power supply server 40 that has received the power supply start request transmits a power supply start command to the power supply apparatus 20 via the communication network 30 (STEP 4-1). In the power supply device 20 that has received this power supply start command, for example, when the red LED 23 is lit (indicated by a black circle in the figure) (STEP 4-2), the user 10 can recognize that the power supply device 20 is supplying power. it can. The power supply device 20 starts power supply to the battery of the electric vehicle 12 by turning on the built-in power supply switch 26, and starts measuring the amount of power used by the built-in measuring device 25 (STEP 4-3). If power supply starts in this way, the user 10 does not have to wait at the place where the power supply device 20 is installed, and can leave the place and return home.

  7, when a power supply completion command is transmitted from the electric vehicle 12 to the power supply device 20 (STEP 5-1), the power supply device 20 completes power supply by turning off the power supply switch 26. For example, when the green LED 24 is turned on (indicated by a black circle in the drawing) (STEP 5-3), the user 10 can recognize that the power supply device 20 is in a power supply completion state. Even when the power supply completion command is not transmitted from the electric vehicle 12 to the power supply device 20, if the power supply device 20 monitors the power amount of the measuring instrument 25 and detects the completion of power supply (STEP5-2), the power supply device 20 Then, the power supply is completed by turning off the power supply switch 26 and the green LED 24 is lit (indicated by a black circle in the figure) (STEP 5-3), so that the user 10 recognizes that the power supply device 20 is in a state of completion of power supply. can do. It is also possible to complete the power supply by specifying the time with a timer built in the power supply apparatus 20. The power supply device 20 transmits a power supply completion notification to the power supply server 40 via the communication network 30 (STEP 5-4), and transmits the used power amount as data measured by the measuring instrument 25 built in the power supply device 20. (STEP5-5). The power supply server 40 calculates a power charge according to the amount of power used, and in addition to the power charge, the equipment calculated from the cost required for the installation of the power supply apparatus 20 and the cost required for the operation of the power supply apparatus 20 Calculate the fee and set the usage fee by adding the facility fee to the aforementioned electricity rate (STEP 5-6). Then, the power supply server 40 transmits a power supply completion notification, a usage fee, and a power consumption amount by electronic mail to the mobile phone 11 of the user 10 via the communication network 30 (STEP 5-7). In addition, about the content transmitted by an e-mail, items other than a power supply completion notification, a usage fee, and a power consumption amount are possible, and the transmission content is arbitrary.

  In the payment process (STEP 6) shown in FIG. 8, the power supply service provider requests the payment agent 50 for a payment process using a credit card for the usage fee (power charge + equipment charge) calculated by the power supply server 40 (STEP 6-STEP 6). 1). The settlement agent 50 executes a settlement process using a credit card (STEP 6-2) and charges the user 10 for a usage fee (STEP 6-3). This settlement process may be performed, for example, by summing up a plurality of uses for each month. As described above, by periodically performing payment processing for a plurality of uses, it is possible to efficiently charge the user 10 for a usage fee.

  In the above embodiment, as a parking lot used by the user 10 who has signed a contract with the power supply service provider, the power supply device 20 is installed in a parking lot attached to an apartment house such as a parking lot of a monthly contract or a condominium. Although the case where it installed is demonstrated, this invention is not limited to this, As shown in FIG. 9, it is in the parking lot of a coin parking lot, a shopping mall, or a hotel where the fee payment machine using a parking ticket is not installed.
