For one, information on the amount of power that can be supplied to the charger and the time transition information (specifically, the cost table 25b and the scheduling table 25c) is sequentially updated to update the storage medium (for example, magnetic storage) Medium) and such information is periodically transmitted to the target charger (including the charger 2) via the communication network.

  Hereinafter, the operation of the vehicle plug-in charging system configured as described above will be described. FIG. 2 shows a flowchart of processing realized by the control unit 17c of the charging condition setting management device 17 executing the program, and FIG. 3 shows an operation procedure of the vehicle side (in-vehicle system 1) and the charger 2.

  First, the power supply information storage control unit 23 of the charger 2 uses the server communication unit of the communication unit 21 repeatedly and periodically (for example, in a four-hour cycle) from the server 3 to supply power table 25a and cost table. 25b is received, and the received tables 25a and 25b are recorded in the storage unit 25 (step 310 in FIG. 3). The reception procedure may be a method of receiving the supply power table 25a and the cost table 25b that the server 3 voluntarily transmits periodically, or the request 23a periodically requests the server for the supply power table 25a and the cost table 25b. The server 3 may transmit the tables 25a and 25b in response to the request, and the power supply information storage control unit 23 may receive them.

  FIG. 4 shows an example of the supply power table 25a for the charger 2, and FIG. 5 shows an example of the cost table 25b. As illustrated in FIG. 4, the supply power table 25 a includes information on the maximum power that can be supplied from the target charger 2 for each date and time. As illustrated in FIG. 5, the cost table 25 b includes information on a charge (amount charged to the vehicle occupant) per unit power amount when charging from the target charger 2 for each date and time.

  Further, the in-vehicle system 1 operates while the vehicle is running and parked, and the control unit 17c stands by until it is determined in step 110 that the vehicle is parked in the process of FIG. Then, the vehicle is parked near the place where the charger 2 is installed (step 210 in FIG. 3). Then, in step 110, the control unit 17c determines that the vehicle is parked based on, for example, that all the drive sources (motors and engines) of the vehicle are stopped and the drive position is in the position P (parking). , Go to step 120.

  In step 120, information on the remaining battery level of the current battery 11 is acquired from the battery monitoring unit 14, and the in-vehicle information terminal 15 is controlled to display the remaining battery level on the display unit. Thereby, the passenger | crew in a vehicle can confirm the present battery remaining charge, and can grasp | ascertain how much he wants to charge (FIG. 3 step 220).

  Thereafter, the control unit 17c accepts the charging condition setting. Specifically, a reception screen that prompts input of charging condition settings is displayed on the display unit of the in-vehicle information terminal 15. FIG. 6 shows an example of this reception screen. The reception screen prompts the user to input the target date and time (target time) for completion of charging, the required power amount required for the charger 2 (power amount), the maximum cost, and the selection of cost priority or time priority (charging condition). It has become.

  The occupant uses the operation unit (installed in the vehicle) of the in-vehicle information terminal 15 to set these charging conditions (that is, the target date and time of charging completion, the required power amount, the maximum cost, and whether the cost priority or time priority) (Selection) is input (step 230 in FIG. 3). Then, the control unit 17c acquires the input charging condition setting, proceeds to step 140, reflects the charging condition setting on the display unit, and records the charging condition setting in the charging condition setting storage unit 17b ( FIG. 3 step 240). At this time, the passenger is in the vehicle, and the vehicle and the charger 2 are not connected by the connection cable 20. After recording the charging condition setting in step 140, the control unit 17c proceeds to step 150, where the plug-in sensing unit 17a indicates that the vehicle is connected (that is, plugged in) to the charger 2 via the connection cable 20. Wait until is detected.

  Thereafter, the passenger gets off the vehicle (step 250 in FIG. 3), and connects (plugs in) the vehicle and the charger 2 with the connection cable 20 (step 260 in FIG. 3). Then, the control unit 17c detects that it is plugged in in step 150, proceeds to step 160, and corrects the required power amount. Specifically, among the charging condition settings recorded in the charging condition setting storage unit 17b, the required power amount is stored in advance in the charging efficiency information input from the battery monitoring unit 14 and the charging condition setting storage unit 17b. Modify based on specific charging efficiency.

  That is, depending on the value of the charging efficiency information (the temperature of the battery 11 and the number of days used), even if it receives 15 kWh of power supplied from the charger 2, it may be able to charge 14 kWh or only 10 kWh. Therefore, the control unit 17c has a correspondence relationship between the value of the charging efficiency information (the temperature of the battery 11, the number of days used) and the charging rate (the amount of power that the battery 11 can actually charge relative to the amount of power received from the charger 2). A charge rate is determined from the charge efficiency information according to this table, and the required charge amount after correction is obtained by dividing the required charge amount by the charge rate.

  Subsequently, in Step 170, the communication unit 16 is used to set the charging condition (the necessary charge amount after correction and the other charging condition setting recorded in the charging condition setting storage unit 17b) via the communication line 20b. The data is transmitted to the charger 2 (step 270 in FIG. 3).

  When the charging scheduling unit 24 of the charger 2 receives the charging condition setting via the communication line 20b and the vehicle-side communication unit of the communication unit 21, the charging notification unit (Ack) receives the reception notification signal (Ack) via the vehicle-side communication unit and the communication line 20b. ) To the in-vehicle system 1. The control unit 17c proceeds to step 180 based on the receipt notification signal received through the communication unit 16, and erases the charging condition setting recorded in the charging condition setting storage unit 17b (step 280 in FIG. 3). ). In this way, by deleting the charging condition setting immediately after receiving the receipt notification by transmitting the charging condition setting, the charging condition setting input this time may be erroneously notified to the charger 2 at the next charging. Disappear.

  Subsequently, the control unit 17 c proceeds to step 190 and outputs a charge start command to the charge control unit 13. As a result, the charging control unit 13 enters a state in which the power received from the charger 2 via the power line 20 a of the connection cable 20 can be output to the charging circuit 12.

  On the charger 2 side, the charging scheduling unit 24 that has received the charging condition setting from the in-vehicle system 1 via the communication unit 2 receives the received charging condition setting and information on the time transition of the amount of power that can be supplied (stored). Based on the supply power table 25a updated to the latest version stored in the unit 25) and the time transition information of the charge (cost table 25b updated to the latest version stored in the storage unit 25) A charging schedule for the battery 11 is created (step 330 in FIG. 3), and the created schedule is recorded in the storage unit 25 as the scheduling table 25c (step 340 in FIG. 3).

  Here, a method for creating a schedule based on the received charging condition setting, the latest power supply table 25a, and the latest cost table 25b will be described. In the following, it is assumed that the date when the charger 2 receives the charging condition setting from the in-vehicle system 1 is 22:00:00 on December 7.

  First, as a first example, as shown in FIG. 6, the charging condition setting received from the in-vehicle system 1 is a target time of 7:00:00 on December 8, and a required power amount is 11 kWh ( Here, a case where the charging rate is 1), the maximum cost is 60 yen, and cost priority is selected will be described. In this case, since the power supply information storage control unit 23 is cost-prioritized, a charging schedule for performing charging by selecting only a time zone in which the power charge is lower than a predetermined charge (here, 8 yen per kWh). Create Therefore, on the basis of the cost table 25b of FIG. 5, an attempt is made to supply the required power amount of 11 kWh only in the time zone from 23:00 to 6:00, which is 5 yen per kWh. In addition, the charging schedule is set so that the interval from 23:00 to 6:00 is divided into units of one hour, and the power supply amount matches the required power amount at the end of the interval, and charging is completed earliest under the conditions. Create Then, according to the supply power table 25a in FIG. 4, the maximum supply power in this time zone is 2 kW, and therefore, as shown in FIG. 7, 1 kW is charged in the section from 23:00 minutes to 24:00. From 0:00 to 5:00, a charging schedule is created so as to charge 2 kW. Further, according to the cost table 25b of FIG. 5, since the total fee for such charging is 5 × 11 = 55 yen, it does not exceed the maximum cost (60 yen) during setting of the charging conditions.

The charging scheduling unit 24 records the charging schedule of FIG. 7 in the storage unit 25 as a scheduling table 25c representing the power supplied for each time interval (step 330).
Further, the charging scheduling unit 24, based on the calculated scheduling table 25c and cost table 25b, provides a charging schedule summary as illustrated in FIG. 8 as a charging completion time (charging completion time), supply power amount (power amount), fee (Cost) is displayed on the display unit of the display / operation unit 22. Thereby, the passenger who got off the vehicle can check the outline of the charging schedule.

  Next, as a second example, as shown in FIG. 9, the charging condition setting received from the in-vehicle system 1 is a target time of 7:00:00 on December 8, and a required power amount is 16 kWh ( Here, it is assumed that the charging rate is 1), the maximum cost is 90 yen, and the time priority is selected. In this case, since the power supply information storage control unit 23 is time-prioritized, the power charge is selected within the range of the power supply capability of the charger 2 by selecting a time slot when the power charge is higher or lower than the predetermined charge. The charging schedule is created so that the charging is completed earliest (and therefore faster than the case of cost priority).

  Therefore, regardless of the cost table 25b in FIG. 5, the maximum power supply for each hour described in the supply power table 25a in FIG. 4 is set to 9 hours from 22:00 to 7:00 as shown in FIG. A charging schedule is created so that the battery 11 is charged by supplying 16 kWh of the required power amount. Further, according to the cost table 25b of FIG. 5, the total charge 10 × 1 × 2 + 5 × 2 × 6 = 80 yen for such charging does not exceed the maximum cost (90 yen) during the charging condition setting.

The charging scheduling unit 24 records the charging schedule of FIG. 10 in the storage unit 25 as a scheduling table 25c representing the power supplied for each time interval (step 330).
Further, the charge scheduling unit 24, based on the calculated scheduling table 25c and cost table 25b, provides a charge schedule summary as illustrated in FIG. 11 as a charge completion time (charge completion time), supply power amount (power amount), charge (Cost) is displayed on the display unit of the display / operation unit 22. Thereby, the passenger who got off the vehicle can check the outline of the charging schedule.

  Next, as a third example, as shown in FIG. 12, the charging condition setting received from the in-vehicle system 1 is a target time of 7:00:00 on December 8, and a required power amount is 16 kWh. (Here, it is assumed that the charging rate is 1), and the case where the maximum cost is 70 yen and the cost priority is selected will be described. In this case, since the power supply information storage control unit 23 is cost-prioritized, a charging schedule for performing charging by selecting only a time zone in which the power charge is lower than a predetermined charge (here, 8 yen per kWh). Create Therefore, on the basis of the cost table 25b of FIG. 5, an attempt is made to supply 16 kWh of the required power amount only in 7 hours from 23:00 to 6:00, which is 5 yen per kWh. Since the power is 2 kW according to the supply power table 25a of FIG. 4, only 14 kWh can be supplied at maximum.

  In this case, the charging scheduling unit 24 removes the condition that the required power amount is satisfied, and creates a charging schedule that performs maximum charging in a time zone that is equal to or lower than a predetermined charge by the target time. Therefore, as shown in FIG. 13, a charging schedule for charging the battery 11 by supplying the maximum 2 kW from 23:00 to 6:00 is created. According to the cost table 25b of FIG. 5, since the total fee for such charging is 7 × 2 × 5 = 70 yen, it does not exceed the maximum cost (70 yen) during setting of the charging conditions.

The charging scheduling unit 24 records the charging schedule of FIG. 13 in the storage unit 25 as a scheduling table 25c that represents the power supplied for each time interval (step 330).
Further, the charge scheduling unit 24, based on the calculated scheduling table 25c and cost table 25b, provides a charge schedule summary as illustrated in FIG. 14 as a charge completion time (charge completion time), a supplied power amount (power amount), (Cost) is displayed on the display unit of the display / operation unit 22. Thereby, the passenger who got off the vehicle can check the outline of the charging schedule.

  At this time, the charging scheduling unit 24 may cause the display unit of the display / operation unit 22 to perform a warning notification that the required charging amount during the charging condition setting cannot be satisfied.

  In the above first to third examples, the total charge due to charging according to the created charging schedule did not exceed the maximum cost during the charging condition setting, but if it exceeds, the actual charge will be A warning notification may be made on the display / operation unit 22 that the charge for setting the charging condition is exceeded.

  In this way, the charging scheduling unit 24 of the charger 2 creates a charging schedule according to the charging condition setting received from the charging condition setting management device 17, and the created charging schedule satisfies a part or all of the charging condition setting. Based on the absence, a warning is given to the passenger who gets off the vehicle.

  In the present embodiment, the charging condition setting is transmitted from the charging condition setting management device 17 to the charger 2 after the passenger gets out of the vehicle and connects the vehicle and the charger 2 with the connection cable 20. Therefore, when the created charging schedule does not satisfy a part or all of the charging condition setting, it is transmitted to the occupant that the charger 2 outside the vehicle is informed rather than in the vehicle as described above. easy.

  In addition, when such a warning notification is made, the charging scheduling unit 24 accepts a change operation of the charging condition setting based on the occupant's input to the operation unit of the display / operation unit 22, and according to the received change operation, The charging condition setting received from the charging condition setting management device 17 is changed, and the charging schedule is created as described above based on the changed charging condition, the supply power table 25a, and the cost table 25b, and the scheduling table 25c is stored. The information may be recorded in the unit 25. In this way, the occupant can change the charging condition setting that is not fully or partially satisfied by the charger 2 without bothering to return to the vehicle.

  After creating the charging schedule (step 320 in FIG. 3), recording the scheduling table 25c (step 330 in FIG. 3), and displaying the summary (step 340 in FIG. 3) as in the first to third examples above, The power supply control unit 26 of the charger 2 reads the scheduling table 25c from the storage unit 25, and controls the power supply control unit 26 according to the read scheduling table 25c, thereby charging the battery 11 according to the scheduling table 25c. Is performed via the power line 20a of the connection cable 20 (step 350 in FIG. 3). Under the control of the supply power control unit 26, the supply power control unit 26 supplies power according to the scheduling table 25 c to the charge control unit 13.

  In the in-vehicle system 1, the charging control unit 13 that has already received a charging start command from the control unit 17 c (see step 190 in FIG. 2) charges the power received from the charger 2 via the power line 20 a of the connection cable 20. Output to the circuit 12. Then, the charging circuit 12 charges the battery 11 with the power received from the charging control unit 13 (step 290). In this way, charging of the battery 11 according to the scheduling table 25c is realized.

  As described above, when the vehicle is not connected to the charger 2 via the connection cable 20, the charging condition setting management device 17 acquires the charging condition setting input by the occupant in the vehicle, and the charging condition setting storage unit 17b. (Steps 130 and 140), and based on the fact that the vehicle is connected to the charger 2 via the connection cable 20, the recorded charging condition setting is transmitted to the charger 2 via the connection cable 20. (Steps 160, 170), the charger 2 charges the battery 11 according to the charging condition setting received from the charging condition setting management device 17 via the connection cable 20.

  Thus, when the vehicle occupant inputs the charging condition setting, the setting is temporarily held in the charging condition setting storage unit 17b of the vehicle. Thereafter, when the occupant gets off the vehicle and connects the charger 2 and the vehicle with the connection cable 20, the stored charging condition setting is sent to the charger 2 via the connection cable 20. Thereby, the charger 2 can charge the battery 11 according to the charging condition setting. And since a passenger | crew does not need to return to a vehicle again in order to input charging condition setting, after leaving a vehicle once in order to connect a vehicle and the charger 2 with the connection cable 20, convenience of a passenger | crew improves. To do.

  The charging condition setting management device 17 corrects the required power amount required of the charger 2 among the recorded charging condition settings based on the charging efficiency information of the battery 11 (step 160), and the corrected required power amount. Is transmitted to the charger 2 via the connection cable 20 (step 170). By doing in this way, the required electric energy transmitted to the charger 2 can be corrected according to the charging efficiency of the battery 11.

  In addition, the charger 2 creates a charging schedule for the battery 11 of the vehicle based on the information on the amount of power supply and the time transition of the charge and the charging condition setting received from the charging condition setting management device 17. Charge according to the created charging schedule. By doing in this way, it can charge with the flexible schedule according to the power supply possible quantity and the time transition of a charge.

  In addition, the power supply side system includes a charger 2 to which the connection cable 20 is connected and a server 3 that can communicate with the charger 2. The charger 2 communicates with the server 3 to supply a power supply amount and a charge. By repeatedly receiving the information on the time transition, the information on the time transition of the power supply amount and the charge is repeatedly updated. Based on the updated information on the power supply amount and the time transition of the charge, the vehicle battery 11 is created, and charging is performed according to the created charging schedule.

  In this way, the charger 2 to which the connection cable 20 is connected acquires information on the amount of power that can be supplied and the time transition of the charge from the server 3, so that the power supply side can supply the amount and the charge that can be supplied. Therefore, it is not necessary to go to a certain position of the charger 2 in order to update the time transition information.

  In addition, the charger 2 selects the information on the amount of power that can be supplied and the time transition information of the charge (power supply table 25a and cost table 25b) and whether the cost priority or time priority received from the charging condition setting management device 17 is selected. Based on the above, if the cost is prioritized, create a charging schedule for charging by selecting a time period in which the power charge is lower than the predetermined charge. If the priority is time, the power charge is higher than the predetermined charge Select a time zone and a low time zone, and create a charging schedule so that charging is completed earlier than in the case of cost priority. In this way, the vehicle occupant can receive charging according to his / her request by making a simple selection between cost priority and time priority.
