  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts will be described with the same reference numerals.

(Embodiment)
First, the configuration of the vehicle charge management system according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a configuration diagram of a vehicle charge management system 100 according to the present embodiment.

  In the present embodiment, an example of an electric vehicle in which a storage battery and a motor that rotates wheels are mounted as the vehicle 7 and the motor is driven using electric power stored in the storage battery will be described. In an electric vehicle, electric power stored in a storage battery can be supplied to a motor, and the vehicle can run by rotating wheels with the motor.

  As shown in FIG. 1, the vehicle charging management system 100 includes a vehicle charging device 1 and a plurality of reservation terminals 4 connected to the vehicle charging device 1.

  The vehicle charging device 1 is installed in a power supply room 2d in the apartment house 2 and is supplied with power from the power supply unit 3 of the power supply room 2d. The vehicle charging device 1 supplies charging power to each vehicle 7 via the power line 5. The power line 5 is stored in the storage unit 6 when not in use. The power supply unit 3 is provided with a circuit breaker (not shown) for preventing overcurrent. In addition, although the vehicle charging device 1 was installed in the power supply room 2d of the apartment house 2, it is not limited to this. For example, you may make it install in the place close to the parking lot outside the housing complex 2.

  The reservation terminal 4 is installed in each of the dwelling 2a, dwelling 2b, and dwelling 2c of the apartment house 2, for example. Reservation input information for charging each vehicle 7 is input from each reservation terminal 4.

  By the way, when the vehicle charging device 1 is jointly used in the housing complex 2, the vehicle charging device 1 is not always free, and the user may be able to use other residents such as at which timing and time. It was difficult to know the usage situation. For this reason, every time the user charges, the user goes out of the residence and goes to the parking lot, and there are many troubles such as the availability of the charging place, whether or not charging is completed, and the request for moving the charged vehicle from the charging place. There was a problem that it was difficult to do.

  Furthermore, since the electric power company raises the charge step by step according to the amount of electric power supplied from the commercial power source, the supplied electric energy is calculated on the assumption that all of the vehicles 7 are charged. If you sign a contract, the electricity charge will be quite high. Further, if a large number of vehicle charging devices 1 are installed in the apartment house 2, the purchase cost increases.

  Therefore, in the present embodiment, as shown in FIG. 1, the vehicle charging device 1 is simultaneously connected to the vehicle charging device 1 via the power line 5 so that the user can connect the vehicle 7 to the vehicle charging device 1 at any time. did. Furthermore, the power supplied from the external power supply unit 3 is suppressed, and the user can charge at a low charge.

  That is, the vehicle charging device 1 is configured as shown in FIG. FIG. 2 is a block diagram showing a configuration of the vehicle charging device 1 according to the embodiment of the present invention.

  As shown in FIG. 2, the vehicle charging device 1 is connected to a plurality of reservation terminals 4 (FIG. 1), and a plurality of vehicles 7 (FIG. 1) based on reservation input information input from these reservation terminals 4. ), A power supply unit 14 that divides the plurality of vehicles 7 to supply the charging power, and a reservation information acquisition unit 11 that acquires reservation input information from the plurality of reservation terminals 4. The charging timing creation unit 12 that creates charging timing management information for each vehicle 7 based on the reservation input information acquired by the reservation information acquisition unit 11, and the charging timing management information created by the charging timing creation unit 12. The power supply unit 14 includes a charging control unit 15 that controls charging power that is supplied to the plurality of vehicles 7 based on the charging power. The charging control unit 15 supplies or stops charging power to the plurality of vehicles 7 in a time division manner.

  With this configuration, the charging timing generation unit 12 generates charging timing management information based on the reservation input information, and the charging control unit 15 performs charging that the power supply unit 14 divides and supplies to the plurality of vehicles 7 based on the charging timing management information. Since the electric power is controlled, the electric power supplied from the external power supply unit 3 is suppressed by divided supply, whereby a plurality of vehicles 7 can be simultaneously connected to the vehicle charging device 1 and charged. The power supply unit 14 may be installed in a location adjacent to the parking lot and controlled remotely from the charge control unit 15. Thereby, the number of the power lines 5 can be reduced to a location adjacent to the parking lot, and can be easily installed.

  For this reason, the user can charge the vehicle charging device 1 by connecting the vehicle 7 at any time without confirming that the vehicle charging device 1 is empty.

  For example, FIG. 3 is a diagram illustrating an example of connection between the vehicle charging device 1 and the vehicle 7 according to the embodiment of the present invention. As shown in FIG. 3, the user does not check the availability of the charging place. The vehicle 7 is stopped as usual in the parking area where the parking area 8 is contracted, the power line 5 as a power feeding cable is taken out from the storage unit 6 provided in each parking place, and the taken-out power line 5 is always connected to the vehicle 7. Can be connected and charged.

  And each user returns to the residence (for example, residence 2a, residence 2b, residence 2c, etc. in FIG. 1) in the apartment house 2, and the authentication process of the vehicle 7 from the reservation terminal 4 installed in the residence. Make a reservation input for charging. In this way, the reservation input for charging can be easily performed from within the house, and the vehicle charging device 1 automatically charges at a predetermined time automatically allocated based on the reservation input information, so that the user completes the reservation. Just do it.

  Thereby, even if it is a case where the some vehicle 7 uses the vehicle charging device 1 jointly, it can make it easy to use.

  As the vehicle charging device 1, even when there are 20 vehicles 7 (for example, electric vehicles) in the parking lot of the apartment house 2, for example, the power capacity assuming one vehicle 7, that is, 10 kW to 20 kW Even when the storage battery mounted on the vehicle 7 has a capacity of 25 kWh to 30 kWh (charging rate 80%), it can be charged.

  When the storage battery of the vehicle 7 is fully charged, for example, a travel of about 150 km is possible with a storage battery of 30 kWh. In general, it is estimated that about half of the vehicles 7 travel 30 km or less per day. Most of the vehicles 7 are not fully charged but are about replenished, and the charging time is shorter than 3 hours.

  Returning to FIG. 2, the vehicle charging device 1 includes a notification unit 13 and notifies each reservation terminal 4 of the registered charging reservation information. Thereby, the user can confirm the reservation status from another resident from the inside of the residence, making it easy to use the vehicle charging device 1.

  In addition, the charging reservation information includes charging completion scheduled time information of each vehicle 7 based on the charging timing management information. Thereby, the user can confirm from the dwelling when the other occupants complete the charging, thereby facilitating the use of the vehicle charging device 1.

  Further, the power line communication unit 10 that communicates with each vehicle 7 using the power line 5 and the charge completion detection unit 18 that detects the completion of charging via each vehicle 7 and the power line 5 are provided. When the charging completion vehicle is detected by the unit 18, a charging end message is notified to the reservation terminal that has reserved and input the detected charging completion vehicle. Thereby, the user can confirm the completion of charging even from within the house, making it easy to use the vehicle charging device 1.

  In addition, the vehicle charging apparatus 1 includes a charge calculation unit 16 that calculates a charge charge in order to charge for charging. The charging fee calculated by the fee calculation unit 16 is notified to the reservation terminal 4 via the notification unit 13 as charging information. The charging method will be described later.

  The vehicle charging device 1 includes a storage unit 17. The storage unit 17 includes charge information 17 a used by the charge calculation unit 16, reservation vehicle information 17 b acquired by the reservation information acquisition unit 11 via the power line communication unit 10, and charging timing management information 17 c generated by the charging timing generation unit 12. The charging information 17d calculated by the fee calculation unit 16 is stored. The charge information 17a, reserved vehicle information 17b, charge timing management information 17c, and billing information 17d will be described later.

  Next, the vehicle charging system 110 when the vehicle charging device 1 is introduced into the apartment house 2 will be described with reference to FIGS. 1, 2, and 4. FIG. 4 is a configuration diagram of the vehicle charging accounting system 110 according to the embodiment of this invention.

  As shown in FIG. 4, the vehicle charging accounting system 110 includes a vehicle charging device 1, a plurality of reservation terminals 4, and a charging management device 23.

  In the housing complex 2 (for example, an apartment, etc.), a reservation terminal 4 is installed in each residence (in FIG. 4, room A of the residence 2a, room B of the residence 2b, room C of the residence 2c).

  In the housing complex 2, since the telephone line 200 is already installed in each residence, a network is constructed using the telephone line 200, and the reservation terminal 4 and the vehicle charging device 1 are connected using the constructed network. To do. For example, a network using the telephone line 200 is constructed using HomePNA (Home Phoneline Networking Alliance) technology. Furthermore, using a VDSL (Very High-Bit-Rate Digital Subscriber Line) device 24, high-frequency data can be superimposed on the telephone line 200 and communicated. Thus, by using the existing telephone line 200, the cost of the network and the installation period can be greatly reduced. This facilitates introduction of the vehicle charge management system 100 (FIG. 1) and the vehicle charge accounting system 110 into the apartment house 2.

  The vehicle charging device 1 is connected to the reservation terminal 4 via the bridge unit 20, the separation device 21 and the telephone line 200.

  The bridge unit 20 converts a power line communication signal from the vehicle charging device 1 into a telephone line communication signal. Further, the telephone line communication signal from the reservation terminal 4 is converted into a power line communication signal. Thereby, the user can perform the reservation input and charge of charge of each vehicle 7 via the vehicle charging device 1 from each reservation terminal 4 in each residence.

  The separation device 21 separates the audio signal and the communication signal superimposed on the telephone line 200. The separation device 21 is connected to a public telephone network 201 and can communicate with an external telephone through the public telephone network 201.

  The VDSL device 24 is connected to the separation device 21 and the external network 202, and transmits / receives communication signals separated by the separation device 21 to / from external devices via the network 202.

  The billing management device 23 is installed in the management room 2e of the apartment house 2 and is connected to the telephone line 200 via the home VDSL device 22.

  The charge management device 23 totals and manages the charging fee calculated for each vehicle 7 by the fee calculation unit 16 based on the fee information 17a (FIG. 2). That is, the charging information 17d sequentially stored in the storage unit 17 of the vehicle charging device 1 is acquired, and the charging information of each vehicle 7 is tabulated and managed based on the acquired charging information 17d. The charge management device 23 is not limited to a dedicated machine, and a personal computer may be used. Thereby, for example, the charge management device 23 automatically counts the charge information charges for each vehicle 7 every month, and bills the user of each vehicle 7 for the use status and the charge for each month. Note that an administrator of the management room 2e may make billing.

  As described above, the vehicle charging system 110 includes the vehicle charging device 1, the plurality of reservation terminals 4 and the charging management device 23, and automatically calculates and manages the charging information of the plurality of vehicles 7. The vehicle charging device 1 eliminates the trouble of separately adjusting the charging fee each time, making it easy to use.

  Next, reservation input of each reservation terminal 4 will be described with reference to FIG. FIG. 5 is a diagram showing a display example of the reservation terminal 4 according to the embodiment of the present invention.

  As shown in FIG. 5, setting input areas 30 to 32 for making a reservation input are displayed on the display unit 4 a of the reservation terminal 4. The display unit 4a is configured by, for example, a touch panel, and can perform an input operation by pressing the displayed region portion with a finger.

  For example, a setting input area 30 for inputting quick charging and a setting input area 31 for inputting normal charging are displayed on the display unit 4a. Further, fee information 17 a is displayed in the setting input area 30 and the setting input area 31. The user selects one of quick charge and normal charge with reference to the charge information 17a. Note that the time can be input in the setting input area 32 during quick charging.

  Next, the charge table 25 in which the charge information 17a used in the vehicle charging device 1 is recorded will be described with reference to FIGS. FIG. 6 is a diagram illustrating an example of the charge table 25 used in the vehicle charging device 1 according to the embodiment of the present invention.

  As shown in FIG. 6, a fee table 25 is recorded as the fee information 17a. In the charge table 25, for example, charge data divided into two time zones according to the charge system of the electric power company is recorded.

  Specifically, in the time zone from 7 o'clock to 19 o'clock, charge data of 30 yen / kWh for quick charge and 20 yen / kWh for normal charge is recorded in the charge table 25. On the other hand, in the time zone from 19:00 to 7 o'clock, charge data of 20 yen / kWh is recorded in the charge table 25 for quick charge and 10 yen / kWh for normal charge. The charge calculation unit 16 (FIG. 2) of the vehicle charging device 1 calculates a charge charge based on the charge table 25.

  In the charge table 25, the quick charge charge is set higher than the normal charge charge. The reason for this charge difference is to guide the user to normal charging with the lowest possible charge to reduce the time designation, thereby making it easier to empty the vehicle charging device 1. Thereby, even when an urgent user occurs, the vehicle charging device 1 can be used. This gives the user a sense of security and makes it easier to use.

  Next, a display example of the display unit 4a when a reservation input is made from the reservation terminal 4 will be described with reference to FIG. FIG. 7 is a diagram showing another display example of the reservation terminal 4 according to the embodiment of this invention. Here, an example in which the order of reservation input is the order of vehicle A, vehicle B, and vehicle C is shown.

  As shown in FIG. 7, when the reservation input is completed, the reservation vehicle information 17b, the completion time information based on the charging timing management information 17c, and the billing information 17d are displayed on the display unit 4a. When approving, “OK” is input from the setting input area 35. On the other hand, if the decision is rejected, “cancel” is input from the setting input area 36.

  The charge calculation unit 16 calculates a charge charge with reference to the charge table 25 when “OK” is input. For example, in a time zone from 7 o'clock to 19 o'clock, all users of the residence 2a (vehicle A in FIG. 7), the residence 2b (vehicle B in FIG. 7), and the residence 2c (vehicle C in FIG. 7) are all When normal charging is reserved, the charge calculation unit 16 calculates 600 yen based on the charge table 25 (normal charging is 20 yen / kWh). In the present embodiment, the storage battery capacity of vehicle A, vehicle B, and vehicle C is set to 30 kWh, respectively, and calculation is performed assuming a full charge. Actually, the charging power amount (kWh) required for each vehicle 7 is detected, and the charge calculation unit 16 calculates the charge charge based on the charge table 25.

  Further, since other registration reservation information 26 to 28 is displayed on the display unit 4a, the user can make reservations such as reservation vehicle information 17b, completion time information based on the charging timing management information 17c, and charging information 17d, for example. Is easy to view and use.

  Next, creation of charging timing management information 17c performed based on the reservation input information from the reservation terminal 4, which is a feature of the present embodiment, and charging control of the vehicle charging device 1 based on the charging timing management information 17c The operation will be described in detail.

  First, a first pattern example of the charging control operation in the vehicle charging device 1 will be described with reference to FIGS. 7, 8, and 9. FIG. 8 is a diagram for explaining the charging timing for the vehicle 7 by the vehicle charging device 1 according to the embodiment of the present invention, and FIG. 9 is a diagram for explaining another charging timing for the vehicle 7 by the vehicle charging device 1.

  In the first pattern example, normal charging is selected and reserved for all vehicles 7. Moreover, the vehicle charging device 1 charges each vehicle 7 based on the registration reservation information 26-28 shown in FIG. Note that the order of reservation input from the reservation terminal 4 is the order of vehicle A, vehicle B, and vehicle C, and the reservation input is performed without any time setting.

  In this case, the vehicle charging device 1 completes charging in the order of the vehicle A, the vehicle B, and the vehicle C, and performs a charging operation that is evenly distributed.

  Specifically, as shown in FIG. 8, for example, when reservations for the vehicle A, the vehicle B, and the vehicle C are made during one hour from the start of 9 o'clock to 10 o'clock, the charging timing creation unit 12 The charging timing management information 17c is set, in which the section 300 for charging A is set from 10 o'clock start to 11 o'clock, 13 o'clock start to 14 o'clock, 16 o'clock start to 17 o'clock. Next, the charging timing creation unit 12 sets the charging timing management in which the section 301 for charging the vehicle B is set from 11:00 to 12:00, from 14:00 to 15:00, and from 17:00 to 18:00. Information 17c is created. The charging timing creation unit 12 sets the charging timing management information for the section 302 for charging the vehicle C from the start at 12:00 to 13:00, from 15:00 to 16:00, and from 18:00 to 19:00. 17c is created.

  As a result, the vehicle charging device 1 creates charging timing management information 17c in which the vehicle A is set at 17:00, the vehicle B is set at 18:00, and the vehicle C is set at 19:00 as completion time information (FIG. 7), and the completion time information is reserved. Notify the terminal 4.

  After the vehicle charging device 1 has created the charging timing management information 17c, the charging control unit 15 controls the power supply unit 14 based on the charging timing management information 17c created by the charging timing creation unit 12, and the vehicle 7 Supply charging power in splits.

  When there are two reservations for the vehicle C next to the vehicle A, as shown in FIG. 9, the charging timing creation unit 12 sets the section 300 for charging the vehicle A from the start at 10:00 to before 11:00. The charging timing management information 17c set from 12:00 to 13:00 and from 14:00 to 15:00 is created, and the section 302 for charging the vehicle C is started from 11:00 to 12:00 before 13:00. From 15:00 to 14:00, charging timing management information 17c set from 15:00 to 16:00 is created.

  The vehicle charging device 1 supplies charging power in a time-sharing manner according to the section set for each vehicle 7 from the power supply unit 14 based on the charging timing management information 17c created by the charging timing creation unit 12.

  Next, a second pattern example of the charging control operation in the vehicle charging device 1 will be described with reference to FIGS. 10 and 11. FIG. 10 is a diagram for explaining still another display example of the reservation terminal 4 according to the embodiment of the present invention, and FIG. 11 is a diagram for explaining yet another timing for charging the vehicle 7 by the vehicle charging device 1.

  In the second pattern example, one quick charge and two normal charge reservations are mixed. Here, reservations for vehicle A, vehicle B, and vehicle C are made one hour before the start of 10:00 to 10:00, and the order of reservation input is the order of vehicle A, vehicle B, and vehicle C, and vehicle A and Assume that vehicle C is normally charged and vehicle B is rapidly charged. Furthermore, in the vehicle B, a reservation input is made for the desired time for completion of charging before 14:00.

  As shown in FIG. 10, the charging information 17d for the vehicle B in the registration reservation information 27 is 900 yen (30 yen / kWh), and the charging information 17d for the vehicles A and C in the registration reservation information 26 and 27 is displayed on the display unit 4a. Is displayed at 600 yen (20 yen / kWh). The completion time information that is the charging timing management information 17c will be described later. For example, in the time zone from 19:00 to 7:00, the charging information 17d for the vehicle B is 600 yen (20 yen / kWh), and the charging information 17d for the vehicles A and C is 300 yen (10 yen / kWh).

  Further, as shown in FIG. 11, the desired time for completion of charging of the vehicle B is set with priority. That is, the charging timing creation unit 12 sets the charging timing management for the section 300 for charging the vehicle A from 10 o'clock to 11 o'clock, from 15 o'clock to 16 o'clock, and from 17 o'clock to 18 o'clock. Information 17c is created.

  Then, the charging timing creation unit 12 sets the charging section 301 from the start at 11:00 to before 14:00 in order to prioritize the desired completion time for charging the vehicle B over the completion time for charging the vehicles A and C. Charge timing management information 17c is created. As described above, the charging timing creation unit 12 gives priority to the desired charging completion time input together with the rapid charging as the reservation input information over the other charging completion times of the normal charging. As a result, charging can be preferentially performed in an emergency, and the user can have a sense of security.

  Thereby, the charging timing preparation part 12 turns the section 302 which charges the vehicle C later, from 14:00 start to 15:00 before, from 16:00 to 17:00, from 18:00 to 19:00 before The set charging timing management information 17c is created.

  As a result, the vehicle charging device 1 creates the charging timing management information 17c in which the vehicle A is set to 18:00, the vehicle B is set to 14:00, and the vehicle C is set to 19:00 as the completion time information of the registration reservation information 26 to 28 (FIG. 10). Then, the completion time information as the charging timing management information 17c is notified to the reservation terminal 4.

  The vehicle charging device 1 supplies charging power in a time-sharing manner according to the section set for each vehicle 7 from the power supply unit 14 based on the charging timing management information 17c created by the charging timing creation unit 12.

  Next, a third pattern example of the charging control operation in the vehicle charging device 1 will be described with reference to FIGS. 12 and 13. FIG. 12 is a diagram for explaining still another display example of the reservation terminal 4 according to the present embodiment, and FIG. 13 is a diagram for explaining yet another timing for charging the vehicle 7 by the vehicle charging device 1 according to the present embodiment. It is.

  In the third pattern example, two time priorities and one no time priority are mixed and reserved.
