Such charge / discharge result data is transmitted from the communication device 220 provided in the in-vehicle device 200, for example, immediately after the charging / discharging of the battery of the vehicle is completed or at a predetermined periodic timing.

  Further, the communication device 120 is set by the power monitoring control center 300 from the communication device 320 provided in the power monitoring control center 300, and the power status information in each area (information on occurrence of power surplus and power shortage) and the power monitoring control center 300. Incentive condition information is received.

  The power monitoring and control center 300 detects the occurrence of power surplus and power shortage for each area of the power system managed by the power company 400 and sets incentive conditions for alleviating the detected power surplus and power shortage. This is a facility for setting, and includes a control device 310 and a communication device 320 as shown in FIG.

  In the present embodiment, when the power monitoring and control center 300 detects the occurrence of power surplus or power shortage in any area, the control device 310 detects power surplus or power shortage based on the detected information. An incentive condition for mitigating, that is, a condition for giving an incentive when charging / discharging within a predetermined period at a charging facility in a predetermined area is set, and information on the set incentive condition is transmitted to the communication device 320. To the vehicle management center 100.

  For example, when the power monitoring control center 300 detects surplus power in any area, the power monitoring and control center 300 performs charging within a predetermined period at a charging facility in the area in order to mitigate the surplus power in that area. An incentive condition for giving an incentive to the user is set. On the other hand, when the power monitoring control center 300 detects a power shortage in any area, the power monitoring control center 300 executes the charging facility in the area within a predetermined period in order to alleviate the power shortage in the area. An incentive condition is set to give an incentive to a user who has stopped charging in the middle or a user who has discharged at a charging facility.

  Note that when setting the incentive condition, the predetermined period is set as appropriate within a range that can alleviate power surplus or power shortage in the target area. In setting incentive conditions, the charging facility is not particularly limited, and any facility that can charge and discharge a battery may be used.

  In the present embodiment, when the power monitoring control center 300 detects occurrence of power surplus or power shortage in a plurality of areas, the power monitoring control center 300 sets incentive conditions for each area, and sets the plurality of set incentive conditions. It transmits to the vehicle management center 100.

  The database 130 is a database that stores information received by the communication device 120 described above. Specifically, the database 130 stores the charge / discharge performance data of the battery provided in the vehicle based on the information received from the communication device 220 provided in the in-vehicle device 200 by the communication device 120. Further, the database 130 stores power status information and incentive condition information in each area based on information received from the communication device 320 provided in the power monitoring control center 300 by the communication device 120.

  The control device 110 includes, for example, a ROM that stores a program, a CPU that executes the program stored in the ROM, and a RAM that functions as an accessible storage device.

  The control device 110 includes battery charge / discharge performance data received from the communication device 220 provided in the in-vehicle device 200, and power status information in each area received from the communication device 320 provided in the power monitoring control center 300. And incentive condition information are stored in the database 130. In this embodiment, when the information on incentive conditions in each area is stored in the database 130, the control device 110 transmits the stored incentive condition information to the in-vehicle device 200 as a charge / discharge promotion notification.

  Here, the charge / discharge promotion notification includes a charge promotion notification for prompting the user to charge the battery, and a discharge promotion notification for prompting the user to stop charging the battery halfway or discharge the battery. Is included. For example, when the incentive condition stored in the database 130 is content that prompts the user to charge the battery, the control device 110 transmits a charge promotion notification to the in-vehicle device 200. On the other hand, when the incentive condition stored in the database 130 prompts the user to stop charging the battery halfway or discharge the battery, the control device 110 causes the in-vehicle device 200 to discharge the battery. Send a promotion notification.

  In addition, as described above, the charge / discharge promotion notification includes information on an incentive condition that an incentive is given when charging / discharging is performed within a predetermined period at a charging facility in a predetermined area. In addition to this, information on charging facilities that recommend charging / discharging among charging facilities existing in the predetermined area may be included.

  In the present embodiment, the control device 110 transmits the charge / discharge promotion notification only to the in-vehicle device 200 for which a contract (demand response contract) for receiving the charge / discharge promotion notification has been made in advance. . Here, the charging / discharging promotion notification may be transmitted to all the in-vehicle devices 200 for which a demand response contract is made, but may be performed only to a specific in-vehicle device 200 among them. For example, when the in-vehicle device 200 is registered in advance to receive only the charge / discharge promotion notification regarding the desired area, the control device 110 transmits the charge / discharge promotion notification according to the charge / discharge promotion notification. This is performed only for the in-vehicle device 200 in which the area is registered.

  In the present embodiment, the charge / discharge promotion notification transmitted to the in-vehicle device 200 is notified to the user via the display 240 provided in the in-vehicle device 200. For example, a map is displayed on the display 240, and a charging promotion area that is an area for prompting the user to charge the battery is displayed on the map. Alternatively, on the map displayed on the display 240, it is also possible to display a discharge promotion area, which is an area for encouraging battery charging or discharging the battery.

  Here, FIG. 2 is a diagram illustrating an example of a method of notifying the user of a charge / discharge promotion notification. In the present embodiment, when the control device 110 transmits both the charge promotion notification and the discharge promotion notification to the in-vehicle device 200, as shown in FIG. 2, charging around the host vehicle on the map is performed. The promotion area (area surrounded by a broken line in FIG. 2) and the discharge promotion area (area surrounded by a one-dot chain line in FIG. 2) are displayed in a distinguishable manner.

  Thereby, according to this embodiment, in order to notify a user of the charge promotion area and the discharge promotion area in the charge / discharge promotion notification in a manner distinguishable from each other, the user intuitively understands the contents of the incentive condition. It is possible to prompt the user to charge / discharge appropriately.

  In FIG. 2, a circle mark is displayed at a position where the charging facility exists on the map. Among the marks indicating these charging facilities, the charging facility located in the charge promotion area is displayed as the charge promotion facility, while the charging facility located in the discharge promotion area is displayed as the discharge promotion facility. Thereby, it is possible to intuitively understand at which charging facility the user can enjoy the incentive, and to prompt the user to charge / discharge more appropriately.

  In FIG. 2, the information on the period for which the incentive set in the incentive condition is given is omitted, but in this embodiment, the period for which the incentive is obtained together with the information on the charge promotion area and the discharge promotion area. May be displayed on the display 240.

  In the present embodiment, when the control device 110 transmits the charge / discharge promotion notification to the in-vehicle device 200 as described above, the vehicle that has transmitted the transmitted charge / discharge promotion notification and the charge / discharge promotion notification. And the like are stored in the database 130.

  In addition, after transmitting the charge / discharge promotion notification to the in-vehicle device 200, the control device 110 refers to the received charge / discharge record data when receiving the charge / discharge record data from the in-vehicle device 200. It is determined whether or not the user of the in-vehicle device 200 has charged / discharged the battery according to the incentive condition of the charge / discharge promotion notification.

  Specifically, the control device 110 extracts the charge / discharge start time and end time, and information on the place where the charge / discharge was performed, from the received charge / discharge record data. And the control apparatus 110 determines whether the user charged / discharged the battery within the range of the area and period set by the incentive condition based on the extracted information.

  When the control device 110 determines that the user has performed charging / discharging of the battery according to the incentive condition of the charge / discharge promotion notification, the control device 110 displays the information on the charge / discharge performance data in the vehicle as information on the corresponding incentive condition. At the same time, the data is transmitted from the communication device 120 to the power monitoring control center 300.

  In the present embodiment, when the control device 110 transmits charge / discharge performance data and corresponding incentive condition information to the power monitoring control center 300 in this way, the power monitoring control center 300 performs power monitoring control. An incentive point to be given to the vehicle is calculated by the control device 310 provided in the center 300.

  The incentive point is a point used for obtaining a price to be paid to the user of the vehicle, and is calculated as follows. For example, when the user receives a charge promotion notification for encouraging charging of the battery and charges the battery within a set area and period according to the incentive condition of the charge promotion notification, the battery is charged. Incentive points are calculated according to the time spent, the amount of power charged, and the charging facility where the charging was performed.

  On the other hand, when the user receives the discharge promotion notification and stops the charging of the battery that has already been executed within the set area and period in accordance with the incentive condition of the discharge promotion notification, Incentive points can be calculated according to the time when charging was stopped, the time when charging was stopped, the remaining battery level when charging was stopped, and the like. Alternatively, when the user discharges within the set area and period according to the incentive condition of the discharge promotion notification, for example, the discharge time, the amount of discharged electric power, and the discharge are performed. Incentive points can be calculated according to the charging facility.

  When the power monitoring control center 300 calculates the incentive points in this way, the power monitoring control center 300 pays the user a price corresponding to the calculated incentive points. In the present embodiment, the consideration paid to the user is not particularly limited, and examples thereof include money, electronic money, coupons, and merchandise.

  As described above, in the present embodiment, a charge / discharge promotion notification is notified to a user who has made a demand response contract in advance, and charging / discharging according to incentive conditions is performed among the users notified of the charge / discharge promotion notification. Give an incentive to the user who went. Therefore, according to the present embodiment, when the power system of each area is stabilized by demand response using a vehicle battery, the target to be given incentive is limited to users who have previously contracted for demand response. In addition, since it is possible to impart incentives fairly to users who have contracted for demand response, it is possible to improve the satisfaction of users participating in demand response.

  In the present embodiment, the timing at which the power monitoring control center 300 pays the user is not particularly limited. For example, immediately after the user performs charge / discharge according to the incentive condition (that is, the user charges / discharges). It may be during a stay at the charging facility where the user has performed, or may be several hours or days after the user performs charging / discharging according to the incentive condition.

  Moreover, in this embodiment, the control apparatus 110 transmits the instruction | indication which charges / discharges the battery of a vehicle with respect to the vehicle-mounted apparatus 200, without transmitting the charging / discharging promotion notification mentioned above, charging / discharging of a battery. May be executed. That is, when the vehicle on which the in-vehicle device 200 is mounted is in a state where the battery can be charged / discharged in accordance with a charge / discharge command input from the outside without requiring a charge / discharge operation by the user, the control is performed. The device 110 may transmit a charge / discharge command to the in-vehicle device 200 without transmitting a charge / discharge promotion notification to cause the battery to be charged / discharged.

  Specifically, first, the control device 110 determines whether or not the vehicle on which the in-vehicle device 200 is mounted is permitted to be charged / discharged without requiring a charge / discharge operation by the user. Next, when it is determined that such permission is granted for the vehicle, the control device 110 refers to the incentive condition stored in the database 130 and the vehicle exists in the area set by the incentive condition. In addition, it is determined whether or not charging / discharging is possible. Here, the state where charging / discharging is currently possible indicates a state where charging / discharging can be started by a charging / discharging command without requiring any work by the user. For example, a charging / discharging plug is connected to the vehicle. Status.

  When the control device 110 determines that the vehicle exists in the area set by the incentive condition and is currently chargeable / dischargeable, the control device 110 performs charge / discharge with respect to the in-vehicle device 200 of the vehicle. A charge / discharge command for executing charge / discharge according to the incentive condition is transmitted without notifying the promotion notification.

  Note that the charge / discharge command includes a charge command for charging the vehicle, a charge stop command for stopping charging for the vehicle that has already been charged, and a discharge command for discharging the vehicle. Is mentioned. In addition, the charge / discharge command includes information such as the time for charging / discharging, the amount of power to be charged / discharged, and the time for stopping charging halfway.

  Thereafter, in the present embodiment, control device 110 stores in database 130 information on the content of the charge / discharge command transmitted to in-vehicle device 200 and information on the vehicle that transmitted the charge / discharge command. Further, the control device 110 causes the in-vehicle device 200 of the vehicle that has been charged / discharged according to the charge / discharge command to transmit the charge / discharge performance data of the vehicle at a predetermined timing, which is received by the communication device 120 and received by the database 130. Remember me.

  Moreover, the control apparatus 110 transmits the charge / discharge instruction | command and the information of charging / discharging track record data which were memorize | stored in the database 130 in this way from the communication apparatus 120 to the electric power monitoring control center 300 with the information of a corresponding incentive condition.

  In the present embodiment, the power monitoring and control center 300 calculates incentive points based on the charge / discharge performance data and the incentive conditions, and the user pays consideration according to the calculated incentive points.

  Thereby, in this embodiment, when permission that charging / discharging may be performed without requiring a charging / discharging operation by the user for a vehicle on which the in-vehicle device 200 is mounted is given to the in-vehicle device 200. Without sending a charge / discharge promotion notification, the charging / discharging command is transmitted to execute the charging / discharging, and the incentive is given to the user based on the charging / discharging performance data executed according to the charging / discharging command. can do. Therefore, according to the present embodiment, it is possible to appropriately give an incentive to the user who has performed charging / discharging according to the charging / discharging command while omitting the trouble of notifying the user of the charging / discharging promotion notification, By causing the vehicle to be charged / discharged regardless of the user's operation, it is possible to efficiently execute the mitigation of power surplus or power shortage in a specific area.

  As described above, when charging / discharging is executed in accordance with the charging / discharging command, whether the incentive point is calculated for the vehicle in addition to the charging / discharging performance data and the incentive condition. No, that is, whether or not the user is permitted to perform charging / discharging without requiring a charging / discharging operation may be considered. For example, in the case where such permission has been granted, as described above, the above-mentioned permission is granted because there is an effect that power surplus or power shortage in a specific area can be efficiently reduced. Incentive points may be added as compared to the case where it is not. Thereby, according to the present embodiment, it is possible to prompt the user that the user can perform charging / discharging without requiring a charging / discharging operation by the user, and alleviate power surplus or power shortage in a specific area. Can be performed more efficiently.
