The solicitation information generation unit generates the solicitation information including information indicating a greater incentive as the size of the request is larger, or the solicitation information is an electric vehicle farther from the parking facility. The solicitation information including the designation of the notification range that is notified up to is generated.

  According to this configuration, the vehicle soliciting device can determine the power supply / demand balance of the entire vehicle charging / discharging device, and can more strongly solicit the vehicle necessary for balancing charging and discharging. As a result, the power supply / demand balance of the entire automobile charging / discharging device can be achieved. In other words, since the stock of electric power in the automobile charging / discharging device can be reduced, it is not necessary to store a large amount of electric power. As a result, it is not necessary to provide a large capacity power storage device. Further, it is not necessary to purchase a large amount of power from the power system or to reversely flow a large amount of power. Therefore, in the vehicle charging station, it is possible to realize a vehicle soliciting device that invites the vehicle to the charging station so that the capacity of the power storage device is reduced and the power quality on the power system side is not deteriorated.

  Specifically, the vehicle charging / discharging device includes a charging / discharging unit connected to an electric vehicle parked in the parking facility, and a power supply unit that supplies power to the charging / discharging unit and receives power from the charging / discharging unit. The power supply unit includes a power storage unit that stores received power and discharges power for power supply, and the charge / discharge management unit corresponds to the amount of power stored in the power storage unit. The value may be used as a power supply / demand balance in the charge / discharge process.

In the present embodiment, charging / discharging unit 101 and the electric vehicle are connected by a power cable. The charging / discharging unit 101 is distributed in the charging station 10. For example, in the case of a large-scale charging station 10 set in a large shopping center, the charging / discharging units 101 are distributed and installed at a plurality of locations.

  The car 2 is parked at the charging station 10. The automobile 2 parked at the charging station 10 is connected to the automobile charging / discharging device 100 via the charging / discharging unit 101 with a power cable. In addition, the automobile 3 is running outside the charging station 10.

  The car 2 is an electric car parked at the charging station 10. That is, the automobile 2 is an automobile that is parked at the charging station 10 and subjected to the charging / discharging process by the automobile charging / discharging device 100. Hereinafter, the automobile means an electric automobile. The electric vehicle includes a battery type electric vehicle that runs only by a motor, and a vehicle that can charge or discharge electric power, such as a plug-in hybrid car that uses a motor and an engine together.

  The automobile 3 is an automobile other than the automobile 2, that is, an electric vehicle outside the charging station 10. For example, the vehicle is traveling outside the charging station 10. In the following description, the traveling automobile includes a stopped automobile.

  The vehicle solicitation apparatus 1 includes a charge / discharge management unit 102, a solicitation information generation unit 103, and a communication unit 104.

  The vehicle soliciting device 1 is a vehicle soliciting device that solicits an electric vehicle to a parking facility equipped with the vehicle charging / discharging device 100.

  The charge / discharge management unit 102 manages charge / discharge power for charge / discharge. More specifically, the vehicle 3 outside the charging station 10 according to the power supply / demand balance in the charging / discharging process, which is charging or discharging of the power performed by the vehicle charging / discharging device 100 for the vehicle 2 parked at the charging station 10. A code indicating a charging process or a discharging process for and a size of a request for soliciting the electric vehicle to the charging station 10 is determined. For example, a code (hereinafter also referred to as a solicitation code) is determined so that the absolute value of the supply and demand balance when the automobile 3 performs charge / discharge processing at the charging station 10 becomes smaller. Also, the larger the absolute value of the current supply-demand balance, the larger the request size. Details of the charge / discharge management unit 102 will be described later.

  The solicitation information generation unit 103 generates solicitation information for soliciting the automobile 3 to the charging station 10 so that a balance between power supply and demand in the charging / discharging process for the automobile 2 performed by the automobile charging / discharging device 100 at the charging station 10 can be achieved. To do. Specifically, solicitation information for solicitation is generated according to the size of the request determined by the charge / discharge management unit 102. More specifically, the solicitation information includes information indicating an incentive obtained when the automobile 3 that has acquired the solicitation information responds to the solicitation. The solicitation information generation unit 103 generates solicitation information including information indicating a greater incentive as the request size is larger, or solicitation including designation of a notification range that is notified to a farther vehicle.

  The power receiving unit 5 receives power from the power grid 4 of the electric power company. Further, the power flows backward to the power grid 4 through the power receiving unit 5. For example, when the power charged in the power storage unit 105 is insufficient, the automobile charging / discharging device 100 purchases power from the power grid 4 via the power receiving unit 5. Further, when electric power exceeding the amount that can be charged in power storage unit 105 flows into power supply unit 130, automobile charging / discharging device 100 sells power to power system network 4 through power receiving unit 5.

  Note that the power supply unit 130 may include only one of the power storage unit 105 and the power receiving unit 5.

  FIG. 2 shows an example of a charge / discharge request of an automobile that visits the charging station 10 sequentially. The car that has visited the charging station 10 is a car that is parked in a parking space provided in the charging station 10 and connected to the charging / discharging unit 101 provided in the automobile charging / discharging device 100. The arrival time is the time when the vehicle arrives at the charging station 10. The vehicle identifier is an identifier for vehicle identification. The vehicle identifier may be a member identifier for power charging / discharging, for example, or license plate information. The charge / discharge request code indicates whether the request for the automobile charge / discharge device 100 of the automobile that has visited the charging station 10 is charging or discharging. The charge / discharge request amount is a request amount for charging or discharging.

  FIG. 3 is an example of a graph showing, in time series, the total charge / discharge power for responding to the charge / discharge request of the vehicle when the vehicle having the charge / discharge request shown in FIG. 2 visits. The vertical axis represents power. The horizontal axis indicates time.

  When a car having a charging request visits the charging station 10, the power increases to the charging side (that is, the positive side of the vertical axis) and disappears when charging is completed (that is, the vertical axis becomes 0). Further, when a car having a discharge request visits, the power increases to the discharge side (that is, the minus side of the vertical axis), and when the discharge is completed, the power disappears (that is, the vertical axis becomes 0). When charging / discharging electric power for meeting the demands of a plurality of automobiles is accumulated, a line graph as shown by a thick line in FIG. 3 is obtained.

  Actually, the charging / discharging power of the car does not become an accurate horizontal broken line as shown in FIG. 3 because the charging / discharging current is adjusted according to the situation of the in-vehicle battery, but here it is simplified for explanation. Yes.

  FIG. 4 is a diagram for explaining an example of a state in which the power supply / demand balance in the charge / discharge process performed by the automobile charge / discharge device 100 is maintained. Similar to FIG. 3, the vertical axis represents power. The horizontal axis indicates time.

  The thick line graph shown in FIG. 4 shows the total charge / discharge power indicated by the thick line in FIG. The broken line graph shown in FIG. 4 is a graph obtained by inverting the power indicated by the bold line graph with respect to the X axis (that is, the axis where power = 0). 4, assuming that the same number of vehicles having requests opposite to the thick line in FIG. 3 visit as shown by the broken line graph, the charging / discharging process performed by the vehicle charging / discharging device 100 at the charging station 10 is performed. Indicates that the supply-demand balance is kept at zero.

  As shown by the arrows in FIG. 4, the vehicle soliciting apparatus 1 according to the present embodiment invites the charging station 10 to a vehicle having a charge / discharge request in the opposite direction to the current supply / demand balance of charge / discharge. Thereby, the power supply-demand balance in the charging / discharging process which the vehicle charging / discharging apparatus 100 performs in the charging station 10 can be brought close to zero.

  Next, operation | movement of the vehicle charging / discharging apparatus 100 provided with the motor vehicle solicitation apparatus 1 which concerns on this Embodiment comprised as mentioned above is demonstrated using the flowchart of FIG. Note that the automobile charging / discharging device 100 is activated before the start of business of the charging station or the like, and is not terminated until an input for termination of the administrator is input after the business is finished.

  (Step S <b> 101) The charging / discharging unit 101 charges / discharges a unit amount of electric power to the automobile 2 in accordance with a charge / discharge request of the connected automobile 2.

  The power used for charging is the power of the power storage unit 105 when the power storage unit 105 stores the power. Further, when power is not accumulated, the grid power acquired from the power grid 4 is used.

  The electric power discharged to the automobile 2 is stored in the power storage unit 105 unless the power storage unit 105 is fully charged. Further, if the power storage unit 105 is in a fully charged state, it flows backward to the power grid 4.

  (Step S <b> 102) The charge / discharge management unit 102 totalizes charge / discharge power for all the cars 2 currently being charged / discharged.

  (Step S <b> 103) The charge / discharge management unit 102 indicates a code indicating whether the solicitation information is to be transmitted to a car that desires “charging” or “discharging” among the cars 3 and a request for the solicitation to be successful. The size D is determined. Hereinafter, D is also referred to as a request size.

  The signs “charging” and “discharging” of the solicitation information mean that solicitation of the automobile that is to be “charged” and the automobile that is to be “discharged”, respectively. The charge / discharge management unit 102 determines which of the automobiles that want to be charged or the automobiles that want to be discharged, according to the power supply / demand balance in the charge / discharge processing. Here, the charge / discharge management unit 102 may use, for example, a value corresponding to the amount of power stored in the power storage unit 105 as a power supply / demand balance in the charge / discharge process. Note that the value corresponding to the electric energy includes, in addition to the electric energy, a value determined for each classified electric energy, a value obtained by converting the electric energy with a function that monotonously increases or decreases monotonously, and the like.

  In addition, the power storage unit 105 receives a request from the vehicle 2 or actually performs the charge / discharge processing in the charging / discharging process at a predetermined time as a power supply / demand balance in the charging / discharging process. The difference may be used. For example, it corresponds to an integral value obtained by integrating the graph shown in FIG. 3 for a predetermined period.

  The charge / discharge management unit 102 sets the sign to “charge” because the charging station 10 wants to sell power when the aggregated power supply-demand balance P is positive. When the aggregated power supply / demand balance P is negative, the charging station 10 wants to buy power, so the charge / discharge management unit 102 sets the sign to “discharge”.

  The size D of the request for solicitation is proportional to the absolute value of P, for example.

D = k | P |
(K> 0)

  If D does not reach the predetermined value, solicitation is not performed. In this case, the processing shown in (Step S104) and (Step S105) is not performed.

  (Step S104) The solicitation information generating unit 103 generates solicitation information for soliciting the traveling vehicle 3 to the charging station 10 according to the size of D.

  Specifically, the solicitation information includes various information as an incentive to make the automobile 3 visit the charging station 10.

  For example, the solicitation information may include discount information indicating a discount rate of at least one of products and services at a store where the charging station 10 is provided. At this time, the solicitation information generation unit 103 generates solicitation information including information indicating a higher discount rate as an incentive as the size of the request is larger.

  The solicitation information may include discount information indicating a discount rate of a charge price in charge / discharge processing or premium information indicating an increase rate of a discharge price. At this time, the solicitation information generation unit 103 generates solicitation information including information indicating a higher discount rate or premium rate as an incentive as the request size is larger.

  In addition, the solicitation information may include point information indicating the number of points that can be exchanged for at least one of a product and a service in a store or the like where the charging station 10 is provided. The solicitation information generation unit 103 generates solicitation information including point information indicating more points as an incentive as the request size is larger.

  More specifically, the solicitation information generation unit 103 refers to a look-up table as shown in FIG. 6, for example, the location range information of the solicited automobile, the premium discount on the charge / discharge price of in-vehicle power, the product, Service discount information, the number of points exchangeable for goods and services may be determined according to the size of D.

  According to the lookup table shown in FIG. 6, if D is less than 100, the vehicle soliciting apparatus 1 does not solicit. If D is 100 or more and less than 300, the automobile soliciting apparatus 1 designates an automobile within a radius of 3 km from the charging station 10 as an automobile to be solicited. When D is “charging”, the vehicle soliciting apparatus 1 sets the selling price of power sold by the vehicle charging / discharging device 100 to the vehicle 3 by 2 yen per unit power. On the contrary, when D is “discharge”, the purchase price of the electric power that the automobile charging / discharging device 100 buys from the automobile 3 is increased by 2 yen per unit electric power. In addition, the car soliciting apparatus 1 gives the passengers of the car who visited the charging station 10 a score at which the target product is 3% OFF. Furthermore, 10 points are given.

  If D is 300 or more and less than 1000, the vehicle soliciting apparatus 1 designates a vehicle within a radius of 5 km from the charging station 10 as a soliciting vehicle. When D is “charging”, the car soliciting apparatus 1 sets the selling price of the electric power sold by the car charging / discharging apparatus 100 to the car 3 by 5 yen per unit power. On the contrary, when D is “discharge”, the purchase price of the electric power that the automobile charging / discharging device 100 buys from the automobile 3 is increased by 5 yen per unit electric power. Furthermore, the vehicle soliciting device 1 gives the vehicle passengers who have visited the vehicle charging / discharging device 100 a score that makes the target product 5% OFF. Furthermore, 10 points are awarded.

  As described above, the solicitation information generation unit 103 generates solicitation information indicating a greater incentive as D increases.

  An example of the solicitation information generated by the solicitation information generation unit 103 is shown in FIG.

  The solicitation information ID is unique identification information generated based on, for example, a date. The solicitation information ID is assigned so that the vehicle side that has received the solicitation information can manage whether the solicitation information is the same as the received solicitation information. For example, the solicitation information ID “2206091331” in FIG. 7 is determined based on the fact that the solicitation information was issued at 13:31 on June 09, 2022.

  In this example, discharge is solicited. Therefore, the purchase price of electricity is higher than usual. Also, product discount information, point additional information, and the like are included. Furthermore, the stay time used as the standard which is time required until the charging / discharging process is completed is included. Further, in FIG. 7, for the sake of explanation, all the information included in the solicitation information is text information. However, actually, the text information other than the character string displayed to the user may not be text information. That is, the solicitation information may include image information, moving image information, and the like.

  (Step S <b> 105) The communication unit 104 notifies the automobile 3 together with the invitation code determined by the charge / discharge management unit 102 and the invitation information generated by the invitation information generation unit 103.

  As a notification method, for example, a method using a mobile phone network is conceivable as in the case of currently performed traffic jam information or a probe service for providing service information.

  For example, when the traveling vehicle 3 constantly notifies the communication unit 104 of the position information of the own vehicle by radio, the communication unit 104 always knows the position of the traveling vehicle. Therefore, it is possible to notify the solicitation information from the charging station 10 to a vehicle within a certain position range.

  (Step S <b> 106) When the administrator ends the automobile charging / discharging device 100, the process performed by the automobile charging / discharging device 100 ends. When not ending, it returns to (step S101) at a fixed timing.

  In addition, although the magnitude | size D of the request | requirement with respect to solicitation demonstrated in the example which is proportional to the absolute value of P, you may calculate D as a value which added the variation | change_quantity of P to the absolute value of P. In that case, as the supply and demand balance of power, not only the current supply and demand balance but also the prediction of the future supply and demand balance can be considered.

  The vehicle soliciting apparatus 1 is effective only when the solicitation information is received by the automobile 3 and a user who is a passenger of the automobile 3 visits the charging station 10. Therefore, an example in which solicitation information is displayed to the user via the in-vehicle terminal device included in the traveling automobile 3 will be described.

  The in-vehicle terminal device included in the traveling automobile 3 is implemented as a function of a car navigation system, for example. In this case, for example, an invitation information display unit 1100 as shown in FIG. 8 is also one of the components of the car navigation system. The solicitation information display unit 1100 includes, for example, a return distance calculation unit 1101, a required power amount calculation unit 1102, a sellable power amount calculation unit 1103, a sales profit calculation unit 1104, and a display unit 1105.

  When the solicitation information receiving unit 1107 provided in the in-vehicle terminal device receives the solicitation information transmitted from the car soliciting device 1, the return distance calculation unit 1101 determines the distance required for the traveling car 3 to return from the current location to the home. Calculate based on map link information. This calculation can be realized as a function of a general navigation system.

  The required power amount calculation unit 1102 calculates the amount of power required to return home by dividing the distance calculated by the return home distance calculation unit 1101 by the power consumption of the vehicle. The power consumption is a value indicating the distance that the car can travel per unit power amount, for example.

  The sellable power amount calculation unit 1103 subtracts the amount of power required for returning home from the in-vehicle battery remaining amount of the own vehicle, and also subtracts a predetermined amount of power amount therefrom to calculate the power amount that can be sold. .

  The sales profit calculation unit 1104 calculates the predicted sales by multiplying the sellable power amount by the purchase price of the solicitation information. In addition, the charging cost is calculated by multiplying the amount of electric power that can be sold by the electricity charge at home, and the difference is used as the predicted profit.

  Hereinafter, the return distance calculation unit 1101, the required power amount calculation unit 1102, the available power amount calculation unit 1103, and the sales profit calculation unit 1104 are collectively referred to as a profit calculation unit 1200.

  The display unit 1105 displays the predicted sales and the predicted profit calculated by the sales profit calculation unit 1104 on the display device 1106 provided in the in-vehicle terminal device together with the solicitation information. An example of display on the display device 1106 is shown in FIG. In FIG. 9, an area 1201 displays that this display is notification of solicitation information and that the code indicates discharge. In the area 1202, the name of the charging station solicited is displayed. In the area 1203, solicitation information converted into user-readable text information is displayed. In the area 1204, as described with reference to FIG. 8, predicted sales and predicted profits that are processed and calculated by the in-vehicle terminal of the host vehicle are displayed. When the passenger of the car presses the “Guidance” button displayed in the area 1205, the vehicle will navigate to the soliciting charging station. The solicitation information display unit 1100 may notify the car solicitation apparatus 1 that the passenger of the car has pressed the “guide” button together with the identification information of the car.

  The example of the in-vehicle terminal device included in the traveling vehicle 3 described above is an example of processing / displaying the solicitation information received from the vehicle soliciting device 1, and there may be various ways of processing / display depending on the vehicle. That is, the in-vehicle terminal device receives the solicitation information from the car soliciting device 1 and the solicitation information receiving unit 1107, and the profit calculating unit 1200 that calculates the profit of the user when soliciting based on the power supply / demand balance of the own vehicle. And a display unit 1105 for causing the display device 1106 to display the calculated profit.

  As described above, according to the vehicle soliciting apparatus 1 according to the present embodiment, the power supply / demand balance in the charging / discharging process performed by the vehicle charging / discharging device 100 at the charging station 10 is determined, and the vehicle for balancing is determined. By soliciting, it becomes possible to reduce the operation of the charging station with high public interest to the user's profit by reducing the cost, and to expand the business opportunities for the user.

(Modification 1)
In the first embodiment, the example in which the automobile soliciting apparatus 1 solicits the automobile to balance the power supply and demand in the charging / discharging process performed by the automobile charging / discharging apparatus 100 in the charging station 10 has been described. In the first modification, an example in which not only the power supply / demand balance in the charging / discharging process performed by the vehicle charging / discharging device 100 in the charging station 10 but also the remaining amount of the storage battery provided in the vehicle charging / discharging device 100 is taken into consideration will be described. To do. The difference from the first embodiment is that (step S103) shown in FIG. 5 is replaced with (step S203) described below. Therefore, only the difference will be described.

  (Step S203) The charge / discharge management unit 102 determines the sign of the solicitation information (either “charge” or “discharge”) according to the following calculation formula in accordance with the remaining amount U of the power storage unit 105 and the change rate V of the remaining amount. And the required size D is determined.

D = | kU + jV |
(K and j are constants, k and j> 0)

  Here, when V is positive, it indicates that the remaining amount of power storage unit 105 is increasing. Further, when V is negative, it indicates that the remaining amount of the power storage unit 105 is decreasing. The solicitation code is “charge” when kU + jV is positive, and “discharge” when negative.

  For example, when the remaining amount of the power storage unit 105 is large and the remaining amount is not in a decreasing direction, there is sufficient power. Therefore, since the charging station wants to sell power, the sign is “charging”. Here, the larger the remaining amount is, and the faster the remaining amount is increased, the larger the request size D is. This means that there is a higher need for a vehicle to be charged from the vehicle charging / discharging device 100. On the other hand, when the remaining amount of the power storage unit 105 is small and the remaining amount is not increasing, power tends to be insufficient. Therefore, since the charging station wants to buy power, the sign is “discharge”. Here, the smaller the remaining amount is, and the faster the remaining amount is decreased, the larger the required size D is. This indicates that there is a higher need to visit a car that discharges to the car charging / discharging device 100.

  If D does not reach the predetermined value, no solicitation is performed. At this time, the vehicle soliciting apparatus 1 does not perform the processing shown in Step S104 and Step S105 of FIG.

(Modification 2)
In the first embodiment, the example in which the automobile soliciting apparatus 1 solicits the automobile 3 so as to balance the power supply and demand in the charging / discharging process performed by the automobile charging / discharging apparatus 100 in the charging station 10 has been described. In Modification 2, an example will be described in which solicitation is performed in consideration of not only the power supply / demand balance in the charge / discharge processing performed by the vehicle charging / discharging device 100 included in the charging station 10 but also the power supply / demand balance information in the grid power network. The difference from the first embodiment is that step S103 shown in FIG. 5 is replaced with step S303 described below. Therefore, only the difference will be described.

  (Step S303) The charge / discharge management unit 102 uses the following formula to determine the sign of the solicitation information (either “charging” or “discharging”) according to the aggregated power P and power price information C of the power grid network 4. And the required size D is determined.

D = | kP−j (C−m) |
(K, j, m are constants, k, j, m> 0)

  Here, the solicitation code is “charge” when kP−j (C−m) is positive and “discharge” when kP−j (Cm) is negative.

  For example, if the supply and demand balance of the charging station is surplus and the price of the grid power is low, the power charging station wants to sell the power, so it is a sign of “charging”. In addition, when the supply and demand balance is insufficient and the price of the grid power is high, it means that it is a sign of “discharge” because it is desired to buy power.

  That is, the charge / discharge management unit 102 according to the present modification uses the power supply / demand balance information in the grid power network 4 as the power supply / demand balance in the charge / discharge process. The power supply / demand balance information in the grid power network 4 is, for example, the power price of the grid power network 4.

  If D does not reach the predetermined value, solicitation is not performed. At this time, the vehicle soliciting apparatus 1 does not perform the processing shown in Step S104 and Step S105 of FIG.

(Embodiment 2)
In the first embodiment, the example in which the automobile soliciting apparatus 1 solicits the automobile to balance the power supply and demand in the charging / discharging process performed by the automobile charging / discharging apparatus 100 in the charging station 10 has been described. On the other hand, in the second embodiment, an example in which a vehicle can be solicited in consideration of a power supply / demand balance between vehicles outside the charging station 10 will be described.

  FIG. 10 is a schematic diagram and a functional block diagram showing a configuration of a charging station 10A provided with the automobile soliciting apparatus 1A in the present embodiment. As shown in FIG. 10, the vehicle soliciting apparatus 1A according to the present embodiment is obtained by adding a traveling car management unit 201 and a solicited car selection unit 202 to the car soliciting apparatus 1 according to the first embodiment. The other components are the same as those in the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The traveling vehicle management unit 201 manages the position of each of the traveling vehicles 3A to 3C outside the charging station 10A and the amount of power for charging / discharging allowed. More specifically, the traveling vehicle management unit 201 uses the communication unit 104 to determine the position information of each of the plurality of electric vehicles 3A to 3C outside the charging station 10A and the charging power amount or discharging power allowed in the charging / discharging process. The allowable power information indicating the quantity is acquired.

  The solicited car selection unit 202 selects a running car that solicits to visit the charging station 10A. More specifically, the solicited car selection unit 202 selects solicited cars that are a plurality of electric cars to be solicited based on the power supply / demand balance and allowable power information in the charge / discharge process. Details will be described later.

  After the solicited car selection unit 202 selects the solicited car, the communication unit 104 notifies the solicitation code and the solicitation information for the solicited car.

  Next, in the present embodiment, an example of a time-series change in the total charge / discharge power in response to the charge / discharge request of the automobile that has visited the charging station 10A will be described with reference to FIGS.

  FIG. 11 shows an example of allowable power information. The vehicle identifier shown in FIG. 11 is an identifier for identifying a vehicle as in the first embodiment. For example, it may be a member identifier for power charging / discharging or a license plate. Here, for example, the car identifier of the car 3A is c1, the car identifier of the car 3B is c2, and the car identifier of the car 3C is c3.

  The current position shown in FIG. 11 is the current position of the automobile. For example, it can be obtained by GPS (Global Positioning System).

  The charging / discharging allowable code shown in FIG. 11 is a code representing whether each of the automobiles 3A to 3C can permit charging or discharge. Further, the charge / discharge allowable amount shown in FIG. 11 is an amount that allows each of the automobiles 3A to 3C to allow charge / discharge at the charging station. The charge / discharge allowable code and the charge / discharge allowable amount may be set by a passenger of the vehicle. Alternatively, the vehicle may automatically calculate. As a method of automatically calculating, for example, each automobile may obtain the amount of power necessary for traveling by dividing the distance to the destination by the average power consumption. After that, when the required amount of power and the remaining battery level of each car are compared, and there is a surplus power amount greater than or equal to a predetermined value, the difference obtained by subtracting the predetermined value from the surplus power amount is defined as the discharge allowable power amount. Also good. Further, when there is only a surplus power amount equal to or less than a predetermined value, a difference obtained by subtracting the surplus power amount from a predetermined value may be used as the charge allowable power amount, and otherwise, neither charging nor discharging may be permitted.

  In addition, with respect to a certain automobile, both charge and discharge allowable codes and charge and discharge allowable amounts may be set. In this case, the traveling vehicle management unit 201 may acquire allowable power information indicating at least one of a charging power amount and a discharging power amount that the electric vehicle outside the charging station 10A allows in the charging / discharging process.

  FIG. 12 is a diagram for explaining that if the vehicles that newly visit the charging station 10 </ b> A can maintain a mutual power supply-demand balance, the supply-demand balance of the entire charging station 10 will not be affected. In FIG. 12, for example, when there is a total charge / discharge power indicated by the same thick line as in FIG. 3 due to charge / discharge requests of automobiles A to J, a plurality of new automobiles K, L, M, N, etc. Even if a car visits, if the mutual charge / discharge demands of the cars K and L, and M and N are the same, it indicates that there is no effect on the overall supply-demand balance. More specifically, as shown in FIG. 12, if the total amount of charge required by the cars K and L is equal to the total amount of discharge required by the cars M and N, they cancel each other. There is no effect on the overall supply-demand balance. In this way, if the total amount of power transaction increases without affecting the supply-demand balance, there is a merit for both the operator and the user of the charging station.

  In the present embodiment, not only soliciting vehicles to bring the supply-demand balance described in the first embodiment closer to zero, but also as shown by the arrows in FIG. Is solicited as a set so as not to affect the balance of supply and demand, thereby increasing the operating rate of the charging station 10A and increasing the transaction volume.

  Next, operation | movement of 100 A of motor vehicle charging / discharging apparatuses provided with 1 A of motor vehicle invitation apparatuses which concern on this Embodiment comprised as mentioned above is demonstrated using the flowchart of FIG.

  The automobile charging / discharging device 100A is activated before the business of the charging station 10A is started, and does not end until the administrator inputs the end after the business ends.

  Steps S101 to S103 shown in FIG. 13 are the same as those in the first embodiment, and a description thereof will be omitted.

  (Step S201) The traveling vehicle management unit 201 communicates with the plurality of vehicles that are traveling outside the charging station 10A through the communication unit 104, thereby obtaining vehicle identifiers, current positions, and allowable power information of the plurality of vehicles. get. Further, the received information is stored. If information about the same car is already stored, the information is updated. More specifically, the traveling vehicle management unit 201 manages the allowable power information of each of a plurality of vehicles, for example, as a data structure as shown in FIG.

  (Step S202) The solicited vehicle selection unit 202 refers to the allowable power information managed by the traveling vehicle management unit 201, so that the charge power amount in the charge / discharge process can be selected from among combinations of vehicles among a plurality of vehicles. The sum of the difference between the amount of discharged power and the difference between the amount of charged power and the amount of discharged power allowed by the soliciting car is within a predetermined range, and the number of soliciting cars is maximized. Select a solicitation car. Selection can be obtained by a general method as a combination optimization problem. In addition, instead of maximizing the number of solicited cars, the solicited car selection unit 202 selects solicited cars so that the number of cars that can be parked in the parking space provided in the charging station 10A matches the number of solicited cars, for example. May be.

  In addition, for example, taking into account that the arrival time varies depending on the range of the distance between the charging station and each of the traveling vehicles (0 to 5 km, 5 km to 10 km, 10 km). Can be expected to maintain a balance between supply and demand. In other words, the solicited car selection unit 202 selects the solicited car from among the cars 3A to 3C that have not been visited, among the cars that have a difference in arrival time at the charging station 10A within a predetermined threshold. Good.

  Furthermore, the solicited car selection unit 202 has previously determined the sum of the difference between the charge power amount and the discharge power amount in the charge / discharge process and the difference between the charge power amount and the discharge power amount allowed by the solicitation car. The solicited car may be selected so that the staying time at the charging station 10A of each solicited car is within the range and at least a part of the staying time overlaps.

  Step S104 is the same as that in the first embodiment, and a description thereof will be omitted.

  (Step S203) The communication unit 104 combines the solicitation code determined by the charge / discharge management unit 102 with the solicitation information generated by the solicitation information generation unit 103, and the traveling vehicle selected in Step S202 (ie, the solicitation vehicle) ).

  Step S106 is the same as that in the first embodiment, and a description thereof will be omitted.

  As described above, according to the vehicle soliciting apparatus 1A according to the present embodiment, the charging / discharging process performed by the vehicle charging / discharging device 100A in the charging station 10A also takes into account the supply / demand balance of the vehicle outside the charging station 10A. You can solicit cars to balance the supply and demand of electricity. As a result, the operation of the charging station with high public interest can be reduced to the user's profit by reducing the cost. Moreover, it becomes possible for the user to expand the opportunities for transactions. Furthermore, so as not to affect the balance between supply and demand, it is possible to increase the operating rate of charging station operation by soliciting vehicles with charging requirements and vehicles with discharging requirements. As a result, it is possible to increase the transaction amount at the charging station 10A.

  The solicited car selection unit 202 according to the present embodiment selects the solicited car so as to balance the supply and demand of electric power in the entire charging station 10A. That is, the solicited automobile selection unit 202 according to the present embodiment has a sum of the power supply / demand balance in the charge / discharge process performed by the automobile charge / discharge device 100A and the power supply / demand balance of a plurality of automobiles outside the charging station 10A. Solicited cars were selected so that they would fall within a certain range. However, the solicited car selection unit 202 may select the solicited car in consideration of only the power supply / demand balance between a plurality of cars outside the charging station 10A.

  In this case, the vehicle soliciting apparatus 1A performs communication with the vehicle 104 outside the charging station 10 and charging / discharging processing that is charging or discharging of power performed by the vehicle charging / discharging device 100A on the vehicle 2. Based on the allowable power information, the traveling vehicle management unit 201 that acquires the allowable power information indicating at least one of the charging power amount and the discharging power amount allowed by the vehicle outside the charging station 10 and the charging station 10A. You may provide the invitation vehicle selection part 202 which selects the invitation vehicle which is the some vehicle used as the object of invitation, and the invitation information generation part 103 which produces | generates the invitation information for performing an invitation. Here, the communication unit 104 notifies the soliciting car of the solicitation information.

  More specifically, the soliciting car selection unit 202 determines that the difference between the charging power amount and the discharging power amount allowed by the soliciting car in the charging / discharging process is within a predetermined range, and charging each soliciting car. The soliciting car may be selected so that at least part of the staying time at the station 10A overlaps.

(Embodiment 3)
In the first embodiment, the example in which the automobile soliciting apparatus 1 solicits the automobile to balance the power supply and demand in the charging / discharging process performed by the automobile charging / discharging apparatus 100 in the charging station 10 has been described. On the other hand, the automobile soliciting apparatus according to Embodiment 3 is an automobile soliciting apparatus that allows the soliciting automobile to make a reservation for charge / discharge processing in accordance with the solicitation. In addition, the automobile charging / discharging device according to the present embodiment manages a parking lot and a lane at the charging station based on a charge / discharge reservation. As a result, the solicited car can make a smooth charge / discharge transaction. As a result, the merit of the soliciting vehicle for solicitation increases.

  FIG. 14 is a schematic block diagram and a functional block diagram showing a configuration of a charging station 10B to which the vehicle soliciting apparatus 1B according to the present embodiment is applied. As shown in FIG. 14, an automobile soliciting apparatus 1B according to the present embodiment is obtained by adding a reservation management unit 301 and a parking lot management unit 302 to the automobile soliciting apparatus 1 according to the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The charge / discharge management unit 102B is configured such that the difference between the charge power amount and the discharge power amount in the charge / discharge process and the difference between the charge power amount and the discharge power amount that the vehicle accepted by the reservation management unit 301 accepts in the charge / discharge process. As a value corresponding to the sum, the power supply / demand balance in the charge / discharge process is calculated. For example, in the charge / discharge management unit 102B, the charge power amount in the charge / discharge process is 20 kWh, the discharge power amount in the charge / discharge process is 25 kWh, the charge power amount allowed by the automobile that has accepted the reservation is 11 kWh, and the automobile that has accepted the reservation is acceptable Assuming that the amount of discharge power to be 10 kWh, (20−25) + (11−10) = − 4 is the power supply / demand balance.

  The reservation management unit 301 accepts a reservation for charge / discharge processing from the solicited soliciting car.

  The parking lot management unit 302 manages the parking space provided in the charging station 10B so that the reserved solicited automobile can smoothly charge and discharge.

  A more detailed functional block diagram of the parking lot management unit 302 is shown in FIG.

  The visit reservation database 3022 stores reservation information.

  The visiting car discriminating unit 3023 discriminates whether the car that has visited the charging station 10B is the solicited car that has made a reservation.

  The reserved car guide section 3024 guides to a certain parking space where a solicited car that has been reserved and visited is secured. For example, referring to FIG. 14 again, the solicited automobile 3D that has made a reservation and visits is guided to an empty parking space 310 for charge / discharge processing by the automobile charging / discharging device 100B.

  The operation of the automobile charging / discharging device 100B including the automobile soliciting apparatus 1B according to the present embodiment configured as described above will be described with reference to the flowchart of FIG.

  The vehicle charging / discharging device 100B is activated before the start of business of the charging station 10B, and does not end until an administrator's end input is input after the end of business.

  Steps S101 to S103 are the same as those in the first embodiment, and a description thereof will be omitted.

  (Step S104B) The solicitation information generation unit 103 generates solicitation information for soliciting the traveling cars 3A to 3C to the charging station 10B according to the size of D.

  As in the first embodiment, for example, referring to a look-up table corresponding to the size of D as shown in FIG. Determine discount information for products and services, and the number of points that can be exchanged for products and services.

  In FIG. 17, the normal solicitation privilege 3101 is the content of the privilege of normal solicitation information, and the content is the same as in the first embodiment. The reservation solicitation privilege 3102 is the content of the privilege when making a reservation by looking at the solicitation information, and the content of the reservation is more beneficial for the user. The vehicle soliciting apparatus 1B not only solicits the charging station 10B but also makes a reservation from the vehicle by transmitting the soliciting information of both the normal soliciting privilege 3101 and the reservation soliciting privilege 3102 to the traveling vehicles 3A to 3C. Prompt. In other words, in the present embodiment, the reservation management unit 301 prompts a reservation by giving a premium incentive with an incentive increased to a car that has made a reservation for a visit.

  FIG. 18 shows a display example when the solicitation information for prompting the reservation is displayed on the in-vehicle terminal device. In the area 3201 shown in FIG. 18, as in the area 1201 shown in FIG. 9, it is displayed that this display is notification of solicitation information and that the solicitation code is discharge. In addition, the name of the charging station solicited in the area 3202 is displayed. In the area 3203, the solicitation information converted into text information that can be read by the passenger of the vehicle, and the predicted sales and the predicted profit that are processed and calculated by the in-vehicle terminal device of the vehicle are displayed. In addition, in the area 3204, solicitation information including a premium incentive when making a reservation is displayed.

  When the vehicle passenger presses the “Reserve” button displayed in the area 3205, a reservation request signal is sent to the vehicle soliciting apparatus 1B. Thereafter, the in-vehicle terminal device starts navigation to the charging station 10B.
