Further, the A electric vehicle 22 is equipped with an ETC on-board device 70 for an electronic toll collection system (hereinafter referred to as "ETC"), and is capable of wireless communication with an antenna at a toll road toll gate, etc. The A electric vehicle 22 is further provided with a V control section 74, which controls the entire A electric vehicle 22 by being connected to the EV drive section 68, the EV connector 62, the ETC on-vehicle device 70, etc. via an in-vehicle wiring 72. Further, the A electric vehicle 22 has a normal license plate 76.

The charging unit 52 is provided with a charging control section 78 and receives information on the meter reading results of the charging meter 59. The charging unit 52 is further provided with an ETC/ID recognition section 80, which identifies the electric vehicle A 22 by wireless communication with the ETC onboard device 70 of the electric vehicle A 22 parked in the parking space 60. - Recognize the ID and report it to the charging control unit 78. In addition, the license plate optical reading unit 82 of the charging control unit 78 optically reads the vehicle registration number that identifies the A electric vehicle 22 by capturing an image of the license plate 76 of the A electric vehicle 22 parked in the parking space 60. is read and reported to the charging control unit 78. In this way, both the ETC/ID recognition unit 80 and the license plate optical reading unit 82 have the function of identifying the electric vehicle parked in the parking space 60 of household A 10. Therefore, in order to identify an electric vehicle, it is sufficient to use either the ETC/ID recognition section 80 or the license plate optical reading section 82, but in the embodiment, both are used together for cross-checking.

As described above, if the ETC/ID recognition unit 80 or the license plate optical reading unit 82 or both identify that it is the A electric vehicle 22 that is parked in the parking space 60, the charging The control unit 78 allows charging from the charging connector 58. In this case, the smart meter 36 reports the power consumption by the house 34 as well as the power consumption due to the charging of the A electric vehicle 22 to the power company 2 via the Internet 6, and the power company 2 charges the reported power rate to the A home 10. do. Note that if the power generation of the solar system 46 covers the charging of the electric vehicle A 22, there is no power consumption via the smart meter 36, so there is no charge for charging. Incidentally, even if the power consumption by the home appliances 44 and the like in the house 34 is covered by the discharge of the storage battery 66, there is no power consumption via the smart meter 36, so there is no charge for that amount.

Next, a case will be explained in which it is determined by either or both of the ETC/ID recognition unit 80 and the license plate optical reading unit 82 that the electric vehicle parked in the parking space 60 is owned by another person. do. This corresponds to, for example, a case where the B electric vehicle 24 is parked at the C household 18 shown in FIG. 2 and is being charged. Although not shown in FIG. 2, it is assumed that the C household 18 has the same configuration as the A household 10, and the B electric vehicle 24 has the same configuration as the A electric vehicle.

To avoid confusion, we will return to the A household 10 and explain the case where the B electric vehicle 24 is parked in the parking space 60 and is being charged. (In the following explanation, the configuration of the electric vehicle A 22 in FIG. Since it is specified that the B electric vehicle 24 is parked in the parking space 60, the communication unit 84 of the charging control unit 78 reports this to the charging management company 4 via the Internet 6. Upon receiving the report, the charging management company 4 checks whether the B electric vehicle 24 has joined the power interchange system, and when the joining is confirmed, reports the fact to the communication section 84 of the charging control section 78 via the Internet 6. do. Based on this report, the charging control unit 78 permits charging of the B electric vehicle 24 from the charging connector 58.

The power meter 59 measures the power supply from the distribution board 42 to the charging connector 58 via the AC-DC converter 56, and reports this to the charging controller 78. The communication unit 84 of the charging control unit 78 reports the measured amount of power supplied to the B electric vehicle 24 to the charging management company 4 via the Internet 6. After receiving the report, the charging management company 4 reports the amount of power supplied to the B electric vehicle 24 to the electric power company 2 via the Internet 6.

In the above, the power consumption of household A reported to the electric power company from the smart meter 36 includes not only the power consumption by household A itself but also the power consumption due to charging of electric vehicle B 24. However, as mentioned above, since the amount of power supplied to the B electric vehicle 24 is reported from the charging management company 4 to the electric power company 2, the electric power company calculates the B electric power from the power consumption of the A household reported from the smart meter 36. Household A 10 is charged the electricity fee after deducting the amount of electricity supplied to vehicle 24. On the other hand, the electric power company charges the B household 12 (see FIG. 1) that owns the B electric vehicle 24 by adding the power consumption due to charging of the B electric vehicle 24 to the electric power consumption by the B household itself. As a result, even if the B electric vehicle 24 is charged at the A household 10, it can be charged by the electric power company in the same way as for charging at the B household 12, and the A household 10 can also charge the electric vehicle of another person. Even if you charge the battery, you will not actually be charged for it. Therefore, an electric vehicle that has joined the power interchange system can be charged in a parking space of another household that has joined the power interchange system, even when away from home.

Note that while the B electric vehicle 24 is being charged, the power consumption of the house A household 10 as determined by the smart meter 36 is the total power consumption in the house 34 as determined by the HEMS 40 and the B electric vehicle as determined by the power meter 59. 24, the difference in power is being supplied from the solar system 46. In this case as well, the electric power company charges household A 10 an electricity fee calculated by subtracting the amount of power supplied to electric vehicle B 24 from household A's power consumption reported by smart meter 36, and owns electric vehicle B 24. The B household 12 is billed by adding the power consumption due to the charging of the B electric vehicle 24 to the power consumption by the B household itself. This means that the power provided from the solar system 46 out of the amount of power supplied to the B electric vehicle 24 is sold from the A household 10 to the electric power company 2.

In addition, in the power interchange system of the present invention, even if a system subscriber, a stranger may charge the battery in the parking space of the home, so for security reasons, the ETC/ID recognition unit 80 or the license plate optical reader The identification information of another person's electric vehicle and the charging date and time information acquired by either or both of 82 are recorded in the storage unit 79 of the charging control unit 78, and can be viewed and understood in the A household 10. In the power interchange system of the present invention, owners of electric vehicles in other households also receive charging in the parking spaces of other households, knowing that such recording will be performed when they become system subscribers.

In the parking space 60 of the A household 10, a parking display warning section 86 controlled by the charging control section 78 is provided at a position easily visible from the road and the parking space for the following purpose. The first purpose is to vacate the parking space 60, but when you plan to return the A electric vehicle 22 in a short period of time and you would not want another person's electric vehicle to occupy the parking space 60 for charging. It is compatible. For this purpose, in the charging control unit 78, it is possible to set the time period during which charging by another person is possible in the storage unit 79 using the manual operation unit 88. If the charging time is available, a message ``Charging available'' is displayed, and at other times, a ``Parking prohibited'' message is displayed.

The charging control unit 78's setting of each household's chargeable time period is collected from the communication unit 84 via the Internet 6 to the charging management company 4, and the charging management company 4 follows this report to determine the charging possible time slots for each household. will be published as map data for the car navigation system 90 installed in electric vehicles. Note that this disclosure is limited to car navigation systems 90 of electric vehicles that have joined the power interchange system. This allows electric vehicles running on the road that are part of the power interchange system to know the nearest home where they can be charged, if necessary.

Note that when the parking display warning section 86 finds that another person's electric vehicle is parked in the parking space 60 even though the parking display warning section 86 is displaying "no parking", the parking display warning section 86 will notify you by voice. Make an announcement asking them to leave. On the other hand, if another person's electric vehicle is parked in the parking space 60 despite the "No Parking" sign, the charging management company 4 will notify the police based on the information from the charging unit 52. Report to that effect.

The second purpose of the parking display warning unit 86 is to prevent electric vehicles that are not part of the power interchange system from attempting to steal power or from parking under the guise of charging. Specifically, based on checking the report from the ETC/ID recognition unit 80 or the license plate optical reader 82, the charging management company 4 determines whether the person parked in the parking space 60 is an electrician who is not subscribed to the power interchange system. When it is discovered that it is a vehicle, it notifies charging control section 78 of this fact. Based on this notification, the charging control unit 78 prohibits charging of the B electric vehicle 24 from the charging connector 58, and displays a message “Parking violation!” on the parking display warning unit 86. Furthermore, the parking display warning unit 86 makes an announcement requesting the driver to leave by voice. On the other hand, when the charging management company 4 also discovers that a vehicle parked in the parking space 60 is not subscribed to the power interchange system, it also reports the fact to the police in parallel with the above.

The third purpose of the parking display warning section 86 is to prevent an electric vehicle owned by another person from remaining in the parking space 60 for an unnecessarily long period of time. Even if the report from the charging management company 4 confirms that the vehicle parked in the parking space 60 is an electric vehicle that is subscribed to the power interchange system, charging may not start immediately after parking. It is necessary to prevent unauthorized use of another family's parking space as a mere parking lot, such as when a vehicle does not leave after charging is complete. For this reason, if an electric vehicle owned by another person remains in the parking space 60 for a predetermined period of time before charging starts or after charging is completed, a message will be displayed saying "Unauthorized Parking" and a voice request will be made to immediately start charging. Or make a warning announcement to request you to leave immediately after charging is complete. Furthermore, if the electric vehicle does not start charging or leave within a predetermined time even after this warning announcement, the charging control unit 78 reports this to the charging management company, and the charging management company 4 receives the report. Based on this, we will also report the matter to the police.

Note that the various features of the present invention are not limited to the above-described embodiments, but can be widely applied to other embodiments. For example, in the above embodiment, the electric power company 4 handles the settlement of the power interchange, but instead, the charging management company 4 handles the settlement of the electric power interchange between households that have joined the power interchange system. The payment may be made by debit or transfer using a registered bank account.

Furthermore, the present invention can be implemented not only for the interchange of electric vehicle charging power between ordinary households, but also for the settlement of charges when electric vehicles are charged in parking lots of general consumer business facilities (restaurants, supermarkets, etc.). . This will allow general consumer business facilities to expand their customer base while cooperating with the development of charging infrastructure for electric vehicles, as well as leave the settlement of charging power provided to customers and the sale of power from solar systems to charging management companies. I can do it.

INDUSTRIAL APPLICATION This invention can be utilized for the charging system of an electric vehicle, a charging device, a power interchange system, an electric power bill settlement system, an electric vehicle, etc., and can promote the installation of a charging system by rationalizing electricity bill settlement etc.
