[0023] (First Implementation)

[0024] The following is for reference Figures 1-9 The power control system 10 according to the first embodiment will be described.

[0025] <Composition of the power control system 10>

[0026] like Figure 1 As shown, the power control system 10 includes multiple electric vehicles 20 and power-consuming facilities 50. Figure 1 This illustrates an example of an electric control system 10 comprising three electric vehicles 20 and a facility 50 equipped with three chargers 60. The number of electric vehicles 20 is not limited to three. The number of chargers 60 is not limited to three. Figure 1 The solid lines shown represent the paths for supplying electricity. Figure 1 The dashed lines shown represent the paths of information communication.

[0027] Facility 50 includes power receiving equipment 51, multiple chargers 60, server 100, communication device 103, and information processing terminal 104. Facility 50 also includes multiple power-consuming loads LD. The loads LD are electrically connected to the power receiving equipment 51. The loads LD may include, for example, air conditioning equipment and lighting equipment installed in facility 50. Facility 50 may be, for example, the office of a car dealership.

[0028] <Electrical Equipment 51>

[0029] The receiving equipment 51 is a device that receives power from the power system EG managed by the power operator. The receiving equipment 51 includes a transformer 52, a switchboard 53, a VCT 54 (Voltage and Current Transformer), a fuel meter 55, and a communication device 56.

[0030] Transformer 52 converts the voltage of the power supplied from the power system EG to a predetermined voltage that can be used by multiple loads LD. Distribution board 53 distributes the power, after being transformed to the predetermined voltage by transformer 52, to the multiple loads LD. VCT 54 converts the high-voltage, high-current power supplied from the power system EG to low-voltage, low-current power that can be used by meter 55. Meter 55 measures the power consumed by the loads LD of facility 50, i.e., the power supplied from the power system EG, based on the power converted by VCT 54.

[0031] The power receiving device 51 is wiredly connected to the server 100, enabling communication between them. The power receiving device 51 is connected to an external communication network 200 via a communication device 56. The power receiving device 51 can also communicate with the server 100 via the external communication network 200. The power receiving device 51 sends information including power usage measured by the fuel gauge 55 to the server 100.

[0032] <Multiple chargers 60 and multiple electric vehicles 20>

[0033] Multiple chargers 60 each have a charging plug 61 and a communication device 62. The multiple chargers 60 are electrically connected to a power receiving device 51. Specifically, the charging plug 61 of each of the multiple chargers 60 is electrically connected to the power distribution board 53 of the power receiving device 51. Figure 1 The illustration shows only the details of one of the multiple chargers 60, and the detailed descriptions of the other chargers 60 are omitted.

[0034] Multiple electric vehicles 20 each possess a motor 30, a rechargeable battery 33, a charging port 32, a charging / discharging circuit 31, a communication device 34, and an information processing terminal 35. The multiple electric vehicles 20 include plug-in hybrid electric vehicles 21 and electric vehicles 22. Figure 1 The illustration shows only the details of one of the multiple electric vehicles 20, and the detailed descriptions of the other electric vehicles 20 are omitted.

[0035] Motor 30 is the drive source for electric vehicle 20. Motor 30 uses electricity stored in battery 33 to drive electric vehicle 20. Information processing terminal 35 has a monitor 35M capable of displaying images. Plug-in hybrid vehicle 21 also has a fuel tank for storing fuel and an engine that consumes fuel to drive plug-in hybrid vehicle 21. Electric vehicle 22 does not have a fuel tank or engine.

[0036] The charging port 32 allows for electrical connection to the charging plug 61 of the charger 60. When the charging plug 61 is electrically connected to the charging port 32, the electric vehicle 20 is electrically connected to the charger 60. The charging / discharging circuit 31 includes a relay for switching the connection and disconnection of the power path from the charging port 32 to the battery 33, and a power conversion circuit. The charging and discharging operations, described later, are performed by controlling the charging / discharging circuit 31.

[0037] The charger 60, electrically connected to the electric vehicle 20, is capable of performing a charging operation. The charging operation is the act of supplying power from the power system EG to the electric vehicle 20 via the receiving device 51. By performing the charging operation via the charger 60, the facility 50 consumes the power supplied from the power system EG. The charger 60 performing the charging operation is a power-consuming load LD.

[0038] The charger 60, which is electrically connected to the electric vehicle 20, is capable of performing a discharge operation. The discharge operation is the operation of supplying the electric vehicle 20 with the electricity stored in the battery 33 toward the facility 50.

[0039] Multiple chargers 60 are each connected to an external communication network 200 via a communication device 62. The chargers 60 can communicate with the server 100 via the external communication network 200. The chargers 60 and the server 100 can also communicate via a wired connection.

[0040] The charger 60 sends information to the server 100 indicating that it is able to supply power from the electric vehicle 20 to the facility 50.

[0041] The charger 60 also sends information to the server 100 indicating whether a new electric vehicle 20 can be connected to it. Specifically, the charger 60 sends information indicating whether its charging plug 61 is connected to the charging port 32. A charger 60 whose charging plug 61 is not connected to the charging port 32 is a charger 60 that can connect to the electric vehicle 20. A charger 60 whose charging plug 61 is connected to the charging port 32 is a charger 60 that cannot connect to the electric vehicle 20.

[0042] The charger 60 also sends charger identification information to the server 100 to identify itself. This charger identification information may include, for example, the location where the charger 60 is installed, its identification number, or its model number.

[0043] The charger 60 also sends information to the server 100 identifying the electric vehicle 20 connected to it. Specifically, the charger 60 obtains vehicle identification information from the electric vehicle 20 connected to it, which identifies the electric vehicle 20. The vehicle identification information will be described later. The charger 60 generates information determining the combination of the connected charger 60 and the electric vehicle 20 by associating the obtained vehicle identification information with its own charger identification information.

[0044] Multiple electric vehicles 20 are each connected to an external communication network 200 via a communication device 34. The electric vehicles 20 are able to communicate with the server 100 via the external communication network 200.

[0045] Electric vehicle 20 sends vehicle identification information to server 100 to identify itself. The vehicle identification information includes the numbers and symbols recorded on the license plate of electric vehicle 20. The vehicle identification information also includes information indicating whether electric vehicle 20 is a plug-in hybrid vehicle 21 or an electric vehicle 22. The vehicle identification information may also include the VIN (Vehicle Identification Number) of electric vehicle 20.

[0046] The electric vehicle 20 also sends information to the server 100 indicating the electrical power stored in the battery 33 of the electric vehicle 20.

[0047] <Server 100>

[0048] Server 100 includes: processing circuitry 101, which executes programs to perform various processes; and storage device 102, which stores programs. Processing circuitry 101 includes a processor. Storage device 102 stores power control programs. Processing circuitry 101 executes the power control programs to perform various processes. Server 100 is connected to an external communication network 200 via communication device 103.

[0049] Storage device 102 stores information received from power receiving device 51, multiple electric vehicles 20, and multiple chargers 60. Specifically, storage device 102 stores the electrical power used by facility 50 at each predetermined time. Storage device 102 stores information indicating the amount of power each of the multiple chargers 60 can supply from electric vehicles 20 to facility 50. Storage device 102 stores information indicating whether each of the multiple chargers 60 can newly connect to an electric vehicle 20. Storage device 102 stores charger identification information for each of the multiple chargers 60. Storage device 102 stores information determining the combination of connected chargers 60 and electric vehicles 20. Storage device 102 stores vehicle identification information for each of the multiple electric vehicles 20. Storage device 102 stores information indicating the electrical power stored in the batteries 33 of each of the multiple electric vehicles 20.

[0050] Server 100 is connected to information processing terminal 104 via communication device 103. Information processing terminal 104 has a monitor 104M for displaying images. Information processing terminal 104 is a terminal installed in facility 50. Information processing terminal 104 is, for example, a terminal used by the administrator of facility 50.

[0051] Server 100 can communicate with multiple portable information processing terminals 300 via external communication network 200. Each portable information processing terminal 300 has a monitor 300M displaying images. Portable information processing terminals 300 may include, for example, business smartphones used by staff of facility 50. Staff of facility 50 may include, for example, managers overseeing electric vehicles 20. Portable information processing terminals 300 may also include wearable terminals and tablet terminals. Wearable terminals may include, for example, wristband-type terminals and necklace-type terminals worn around the neck.

[0052] <Peak shaving and valley filling of electricity based on charging and discharging actions>

[0053] In most cases, the larger the contracted electricity value, the higher the base cost of electricity supplied from the power system (EG). Contracted electricity is set based on the maximum electricity demand over the past year. Maximum electricity demand is the maximum value of electricity used within each predetermined demand period. For example, a demand period might be 30 minutes.

[0054] If the electricity consumption in a certain demand period exceeds the maximum electricity demand in the past year, a new contracted electricity capacity is set based on the electricity consumption in that demand period. In order to keep the base cost low, the electricity consumption in each demand period needs to be suppressed to a value below the maximum electricity demand in the past year.

[0055] The processing circuit 101 controls the charging and discharging operations of each charger 60. Thus, the power control system 10 achieves peak shaving and valley filling of electricity demand. Peak shaving and valley filling refers to suppressing electricity consumption during each demand period to a value below the maximum electricity demand of the past year.

[0056] For example, the processing circuit 101 controls the charging and discharging operations of each charger 60 to ensure that the power consumption of facility 50 at any given time does not exceed the maximum power demand of facility 50 in the past. The given time may be a shorter period than the demand period. Thus, the power control system 10 prevents the power consumption at any given time from exceeding the maximum power demand of the past year.

[0057] Figure 2 The solid line C1 shown represents the electricity consumption over a given period of time, from 0 to 24 hours, without charging or discharging operations. In other words, solid line C1 is a load curve representing the time-series change in electricity consumption for each given period. Electricity consumption tends to be higher during the day than at night. A given period is, for example, 30 minutes, which is the same as the demand period.

[0058] like Figure 2 As shown, the maximum power consumption at each given time without charging or discharging is "L1". Here, "L1" is also the maximum power demand in the past.

[0059] The dashed line B1 represents the change in power consumption when a charging action was performed between 10:00 and 15:00. The maximum power consumption when a charging action was performed between 10:00 and 15:00 is "L2", which is greater than "L1".

[0060] The dashed line B2 represents the shift in power consumption when charging is performed from 0:00 to 3:00 and from 22:00 to 24:00, and when discharging is performed from 10:00 to 15:00. During the periods from 0:00 to 3:00 and from 22:00 to 24:00, the load LD other than the charger / discharger 60 undergoing charging consumes little power, so even when charging is performed, the power consumption does not exceed "L1". When discharging is performed from 10:00 to 15:00, facility 50 consumes power supplied from the power system EG and from the electric vehicle 20 during this period. Therefore, compared to the case where neither charging nor discharging is performed, as shown by the solid line C1, the maximum power consumption is "L3", which is smaller than "L1".

[0061] <Notification of connection requests based on the power usage forecast for the next day by the processing circuit 101>

[0062] In order to achieve peak shaving and valley filling of electricity using electric vehicle 20, electric vehicle 20 that can supply power to facility 50 needs to be connected to charger 60.

[0063] The power control system 10 performs a series of processes at predetermined times to enable the electric vehicle 20, which can supply power to facility 50, to connect to the charger 60. This series of processes includes a forecasting process that predicts the power consumption for each predetermined time of the next day. This series of processes also includes a connection request notification process that, if any of the predicted power consumption for each predetermined time exceeds a predetermined value DE, notifies the electric vehicle 20, which can supply power to facility 50, of a request to connect to the charger 60 on the predicted day. Hereinafter, the step numbers of each process are represented by numbers beginning with "S".

[0064] like Figure 3 As shown, if this series of processes begins, in process S10, processing circuit 101 obtains the information needed to predict the power consumption at each predetermined time of the next day. For example, processing circuit 101 obtains the weather data for the next day and the power consumption at each predetermined time in the past, which is stored in storage device 102. Then, processing circuit 101 causes the process to proceed to S11.

[0065] In the processing of S11, the processing circuit 101 predicts the electricity usage for each predetermined time of the next day based on the acquired information. The processing circuit 101 uses known methods to predict the electricity usage for each predetermined time of the next day.

[0066] For example, processing circuit 101 predicts the electricity usage for each given time of the next day based on weather data for the next day and the electricity usage for each given time in the past. Processing circuit 101 can be configured to use a learning model learned through machine learning to predict the electricity usage for each given time of the next day for facility 50.

[0067] like Figure 4 As shown, processing circuit 101 executes processing S11 at time "T1" on day "A". Time "T1" is, for example, a time on day "A" that precedes the time of the morning meeting of facility 50. Through processing S11, processing circuit 101 obtains a predicted load curve P1 representing the time series change of predicted electricity usage at each given time on the next day "A" (i.e., day "A+1"). Then, processing circuit 101 initiates processing... Figure 3 S12 is shown.

[0068] exist Figure 3 In the process shown in S12, the processing circuit 101 determines whether there are time periods during which the electricity consumption at each predetermined time of the predicted second day (at time "T1") exceeds a predetermined value DE. The predetermined value DE is, for example, the maximum electricity demand of facility 50. If the electricity consumption at any of the predetermined times of the predicted second day (at time "T1") does not exceed the predetermined value DE (S12: No), the processing circuit 101 terminates. Figure 3 The series of processes shown.

[0069] like Figure 4 As shown, during the period from time "T2" to time "T3" on day "A+1", the predicted electricity consumption exceeds a predetermined value DE. If the predicted electricity consumption at any predetermined time on the next day exceeds the predetermined value DE (S12: Yes), the processing circuit 101 initiates processing. Figure 3 S13 is shown.

[0070] exist Figure 3In the process shown in S13, the processing circuit 101 obtains information needed to select the recommended vehicle 20RE, which is connected to the charger 60, from among the plurality of electric vehicles 20. Specifically, the processing circuit 101 obtains information from the storage device 102 indicating whether each of the plurality of electric vehicles 20 is a plug-in hybrid vehicle 21 or an electric vehicle 22. In addition, in the process of S13, the processing circuit 101 obtains information needed to select the recommended charger 60RE from among the plurality of chargers 60 as the charger 60 to which the recommended vehicle 20RE is connected. Specifically, the processing circuit 101 obtains information from the storage device 102 indicating the amount of power that each of the plurality of chargers 60 can supply from the electric vehicle 20 to the facility 50. Then, the processing circuit 101 proceeds to S14.

[0071] In the process of S14, the processing circuit 101 performs a vehicle selection process to select a recommended vehicle 20RE from among the multiple electric vehicles 20 as the electric vehicle 20 to be connected to the charger 60. In addition, in the process of S14, the processing circuit 101 also performs a charger selection process to select a recommended charger 60RE from among the multiple chargers 60 as the charger 60 to be connected to the recommended vehicle 20RE.

[0072] Processing circuit 101 selects at least one recommended vehicle 20RE and at least one recommended charger / discharger 60RE so that the power used does not exceed a predetermined value DE. Processing circuit 101 selects the recommended vehicle 20RE and the recommended charger / discharger 60RE, for example, in a manner that allows power to be supplied from the electric vehicle 20 to the facility 50 for the amount exceeding the predetermined value DE during the predicted period of time when the power used exceeds the predetermined value DE.

[0073] like Figure 5 As shown, in the case where multiple electric vehicles 20 include at least one plug-in hybrid vehicle 21 and at least one electric vehicle 22, the processing circuit 101 selects the plug-in hybrid vehicle 21 as the recommended vehicle 20RE in the processing of S14.

[0074] In the processing of S14, the processing circuit 101 selects the charger 60 with the largest power supply from the electric vehicle 20 to the facility 50 as the recommended charger 60RE.

[0075] exist Figure 5 In the example shown, there is a charger 60A capable of supplying 6kW of power from the electric vehicle 20 to the facility 50, and a charger 60B capable of supplying 3kW of power from the electric vehicle 20 to the facility 50. In this case, the processing circuit 101 selects the charger 60A as the recommended charger 60RE in the processing of S14.

[0076] After selecting the recommended vehicle 20RE and the recommended charger 60RE, the processing circuit 101 initiates processing. Figure 3 S15 is shown.

[0077] The processing circuit 101 can also select multiple recommended vehicles 20RE and multiple recommended chargers 60RE.

[0078] exist Figure 3 In the process shown in S15, the processing circuit 101 performs a notification process for a connection request, which is a request to connect the electric vehicle 20, which is capable of supplying power to the facility 50, to the charger 60. Specifically, the processing circuit 101 performs a notification process for a first connection request as a connection request, which enables the recommended vehicle 20RE to connect to the recommended charger 60RE.

[0079] The power control system 10 notifies the information processing terminal 104 installed in facility 50 of a first connection request. The power control system 10 also notifies the office staff's portable information processing terminal 300 via external communication network 200. Furthermore, the power control system 10 notifies the manager of electric vehicle 20's portable information processing terminal 300 via external communication network 200. Finally, the processing circuit 101 terminates. Figure 3 The series of processes shown.

[0080] <Image showing the connection of electric vehicle 20 to charger 60 on the following day>

[0081] like Figure 6 As shown, the first request image IM1 is displayed on the monitor 104M of the information processing terminal 104 that has been notified of the first connection request. The first request image IM1 is an example of an image that prompts the electric vehicle 20 to be connected to the charger 60 the following day. The first request image IM1 is also displayed on the monitor 300M of the portable information processing terminal 300 that has been notified of the first connection request, and on the monitor 35M of the information processing terminal 35 that has been notified of the first connection request.

[0082] The first request image IM1 contains the date and time of the day on which the recommended vehicle 20RE is connected to the recommended charger 60RE. Specifically, the first request image IM1 shows the date and time of the day after the processing circuit 101 notifies the first connection request. The first request image IM1 contains the number of recommended vehicles 20RE.

[0083] The first requested image IM1 includes a first part image IP1, a second part image IP2, and a third part image IP3.

[0084] The first image IP1 represents the recommended vehicle 20RE. The second image IP2 represents the recommended charger 60RE. The third image IP3 represents the time period during which the recommended vehicle 20RE shown in the first image IP1 and the recommended charger 60RE shown in the second image IP2 will be connected.

[0085] exist Figure 6 The first portion of image IP1 shown depicts the first vehicle, the second vehicle, and the third vehicle as recommended vehicles 20RE. The first portion of image IP1 may also display identification information for recommended vehicles 20RE. For example, the first portion of image IP1 may display the numbers and symbols of the license plate recorded on recommended vehicles 20RE.

[0086] exist Figure 6 The second part of image IP2 shows a first charger / discharger, a second charger / discharger, and a third charger / discharger as recommended charger / dischargers 60REs. The first charger / discharger is the recommended charger / discharger 60RE for connecting a first vehicle. The second charger / discharger is the recommended charger / discharger 60RE for connecting a second vehicle. The third charger / discharger is the recommended charger / discharger 60RE for connecting a third vehicle.

[0087] exist Figure 6 The third image, IP3, shows the time period from 9:00 to 12:00 as the time when the first vehicle was connected to the first charger. The third image, IP3, also shows the time period from 9:00 to 12:00 as the time when the second vehicle was connected to the second charger. The third image, IP3, further shows the time period from 9:00 to 12:00 as the time when the third vehicle was connected to the third charger. "9:00 to 12:00" refers to the period from 9:00 to 12:00.

[0088] If the portion of the first request image IM1 that is displayed as "Confirmed" is selected, then the first request image IM1 will not be displayed.

[0089] <Notification of connection requests based on the daily electricity usage predicted by processing circuit 101>

[0090] The processing circuit 101 also performs a series of processes at predetermined times, including: a prediction process that predicts the electricity usage for each predetermined time of the day, and a notification process that notifies the connection request if any of the predicted electricity usage for each predetermined time of the day exceeds a predetermined value DE.

[0091] like Figure 7 As shown, if this series of processes begins, in process S20, processing circuit 101 obtains the information needed to predict the electricity usage for each predetermined time of the day in which the process is performed. For example, processing circuit 101 obtains the weather data for the day and the electricity usage for each predetermined time up to the previous day stored in facility 50 of storage device 102. Then, processing circuit 101 causes the process to proceed to S21.

[0092] In the processing of S21, the processing circuit 101 predicts the electricity usage for each predetermined time of the day based on the acquired information. The processing circuit 101 uses known methods to predict the electricity usage of facility 50 for each predetermined time of the day.

[0093] For example, processing circuit 101 predicts the electricity usage of facility 50 for each given time of the day based on the weather data of the day and the electricity usage of facility 50 for each given time up to the previous day. Processing circuit 101 may be configured to use a learning model learned through machine learning in order to predict the electricity usage of facility 50 for each given time of the day.

[0094] like Figure 8 As shown, processing circuit 101 executes processing S21 at time "T4" on day "A+1". Time "T4" is, for example, a time on day "A+1" that precedes the meeting time of facility 50. Through processing S21, processing circuit 101 obtains a predicted load curve P2 representing the time series changes in predicted power consumption for each given time after time "T4" on day "A+1". Then, processing circuit 101 proceeds to processing S22.

[0095] exist Figure 7 In the process shown in S22, the processing circuit 101 determines whether there are time periods in which the electricity consumption predicted at each predetermined time of the day at time "T4" exceeds the predetermined value DE. If the electricity consumption predicted at any given time of the day at time "T4" does not exceed the predetermined value DE (S22: No), the processing circuit 101 terminates. Figure 7 The series of processes shown.

[0096] like Figure 8As shown, during the period from time "T2" to time "T3", the predicted power consumption exceeds a predetermined value DE. If the predicted power consumption at any given time of the day exceeds the predetermined value DE (S22: Yes), the processing circuit 101 causes the processing to proceed to S23.

[0097] exist Figure 7 In the process shown in S23, the processing circuit 101 obtains the information needed to select the electric vehicle 20 connected to the charger 60, i.e., the recommended vehicle 20RE, from among the multiple electric vehicles 20. For example, with Figure 3 The processing in S13 is the same as shown; the processing circuit 101 retrieves information from the storage device 102 indicating whether each of the plurality of electric vehicles 20 is a plug-in hybrid vehicle 21 or an electric vehicle 22. In addition, in the processing in S23, the processing circuit 101 retrieves information needed to select the charger 60 to connect to the recommended vehicle 20RE from among the plurality of chargers 60, i.e., the recommended charger 60RE. For example, with... Figure 3 The processing is the same as in S14. Processing circuit 101 obtains information from storage device 102 indicating that each of the plurality of chargers 60 can supply power from electric vehicle 20 to facility 50. Furthermore, processing circuit 101 also obtains information from storage device 102 indicating whether each of the plurality of chargers 60 can be connected to electric vehicle 20. Processing circuit 101 also obtains information from storage device 102 determining the combination of the connected chargers 60 and electric vehicle 20. Then, processing circuit 101 proceeds to S24.

[0098] In the process of S24, the processing circuit 101 performs vehicle selection processing to select the electric vehicle 20 connected to the charger 60, i.e., the recommended vehicle 20RE, from among the multiple electric vehicles 20.

[0099] In the process of S24, the processing circuit 101 also performs a charger selection process to select the charger 60 connected to the electric vehicle 20 from among the plurality of chargers 60, that is, to recommend the charger 60RE.

[0100] and Figure 3 The process is the same as S14 shown. The processing circuit 101 selects at least one recommended vehicle 20RE and at least one recommended charger 60RE in such a way that the power used does not exceed a predetermined value DE. For example, the recommended vehicle 20RE and the recommended charger 60RE are selected in such a way that during the predicted period of time when the power used on a given day exceeds the predetermined value DE, power corresponding to the amount exceeding the predetermined value DE can be supplied from the electric vehicle 20 to the facility 50.

[0101] In the process of S24, the processing circuit 101 also performs the process of determining whether the selected recommended vehicle 20RE is connected to the selected recommended charger 60RE. Then, the processing circuit 101 causes the process to proceed to S25.

[0102] In the processing of S25, the processing circuit 101 executes a notification process for a connection request, namely, a notification of a request to connect the electric vehicle 20, which can supply power to the facility 50, to the charger 60. Specifically, the processing circuit 101 executes a notification process for a second connection request, namely, a notification of a connection request to connect the recommended vehicle 20RE to the recommended charger 60RE. The second connection request includes a determination result of whether the recommended vehicle 20RE and the recommended charger 60RE are connected.

[0103] The power control system 10 notifies the information processing terminal 104 installed in facility 50 of a second connection request. The power control system 10 also notifies the portable information processing terminal 300 held by staff members of the office. The power control system 10 further notifies the portable information processing terminal 300 held by the manager of the electric vehicle 20. The power control system 10 then notifies the information processing terminal 35 installed in the electric vehicle 20. Finally, the power control system 10 notifies the information processing terminal 35 installed in the recommended vehicle 20RE of a second connection request. Then, the processing circuit 101 terminates. Figure 8 The series of processes shown.

[0104] <Image showing the connection between electric vehicle 20 and charger 60 on the same day>

[0105] like Figure 9 As shown, the second request image IM2 is displayed on the monitor 104M of the information processing terminal 104 that has been notified of the second connection request. The second request image IM2 is an example of an image that prompts the electric vehicle 20 to be connected to the charger 60 on the same day. The second request image IM2 is also displayed on the monitor 300M of the portable information processing terminal 300 that has been notified of the second connection request and on the monitor 35M of the information processing terminal 35 that has been notified of the second connection request.

[0106] The second request image IM2 contains the date and time of the day the recommended vehicle 20RE is connected to the recommended charger 60RE. Specifically, the second request image IM2 displays the date and time of the day the processing circuit 101 notifies the second connection request. The second request image IM2 also contains the number of recommended vehicles 20RE.

[0107] The second request image IM2 contains a fourth image IP4, a fifth image IP5, and a sixth image IP6.

[0108] Image IP4 in Part 4 represents the recommended vehicle 20RE. Image IP5 in Part 5 represents the recommended charger 60RE. Image IP6 in Part 6 represents the time period during which the recommended vehicle 20RE shown in Image IP4 in Part 4 will be connected to the recommended charger 60RE shown in Image IP5 in Part 5.

[0109] exist Figure 9 The fourth image IP4 shown depicts the first vehicle, the second vehicle, and the third vehicle as recommended vehicles 20RE. The display method of the fourth image IP4 is the same as that of the first image IP1. The identification information of recommended vehicle 20RE can also be displayed in the fourth image IP4. For example, the numbers and symbols recorded on the license plate of recommended vehicle 20RE can be displayed in the fourth image IP4.

[0110] exist Figure 9 The fifth part of the image IP5 shows a first charger, a second charger, and a third charger as recommended chargers 60RE.

[0111] exist Figure 9 Image IP6 in the sixth section shows the time period from 9:00 to 12:00 as the period during which the first vehicle was electrically connected to the first charger / discharger. Image IP6 in the sixth section shows the time period from 9:00 to 12:00 as the period during which the second vehicle was electrically connected to the second charger / discharger. Image IP6 in the sixth section shows the time period from 9:00 to 12:00 as the period during which the third vehicle was electrically connected to the third charger / discharger.

[0112] The second request image IM2 also includes a seventh part image IP7 indicating whether the recommended vehicle 20RE and the recommended charger 60RE are electrically connected.

[0113] If the recommended vehicle 20RE and the recommended charger / discharger 60RE are not electrically connected, the IP7 image in Part 7 will display "Please connect the recommended vehicle". If the recommended vehicle 20RE and the recommended charger / discharger 60RE are electrically connected, the IP7 image in Part 7 will display "OK".

[0114] exist Figure 9 In the example shown, the first vehicle is electrically connected to the first charger / discharger. Therefore, in the seventh part of the image (IP7), in... Figure 9 In the case of the second request image IM2 shown, "OK" is displayed as the connection status between the first vehicle and the first charger / discharger. Figure 9 In the example shown, the second vehicle is electrically connected to the second charger / discharger. Therefore, in the seventh part of the image (IP7), in... Figure 9In the case of the second request image IM2 shown, "OK" is displayed as the connection status between the second vehicle and the second charger / discharger. Figure 9 In the example shown, the third vehicle is not electrically connected to the third charger / discharger. Therefore, in the seventh part of the image, IP7, Figure 9 In the case of the second request image IM2 shown, the connection status of the third vehicle and the third charger is displayed as "Please connect the recommended vehicle".

[0115] If the portion of the second request image IM2 that is displayed as "Confirmed" is selected, the second request image IM2 will no longer be displayed.

[0116] <Function of the First Embodiment>

[0117] like Figure 3 as well as Figure 7 As shown, the processing circuit 101 of the power control system 10 notifies a connection request if the predicted power consumption at any given time exceeds a predetermined value DE. Thus, the power control system 10 prompts the electric vehicle 20, capable of supplying power to the facility 50, to connect to the charger 60.

[0118] <Effects of the First Implementation>

[0119] (1-1) It is easy to achieve peak shaving and valley filling using the electricity of electric vehicle 20.

[0120] (1-2) such as Figure 3 As shown, the processing circuit 101 performs prediction processing to predict the power consumption for each predetermined time of the next day, and notification processing to notify a first connection request as a connection request on the day when it is predicted that there is a time period in which the predicted power consumption exceeds a predetermined value DE. That is, the power control system 10 predicts the power consumption for each predetermined time of the previous day, and prompts the connection of the electric vehicle 20, which is capable of supplying power to the facility 50, to the charger 60 on the previous day.

[0121] Therefore, preparations can begin the day before for implementing peak shaving and valley filling for the next day's use of electric vehicle 20. For example, to prepare for peak shaving and valley filling the next day, one could connect electric vehicle 20 to charger 60 in advance the day before. Alternatively, to prepare for peak shaving and valley filling the next day, one could adjust the usage schedule of electric vehicle 20 the day before.

[0122] (1-3) such as Figure 7As shown, the processing circuit 101 performs prediction processing to forecast the electricity usage for each predetermined time of the day, and notification processing to notify a second connection request as a connection request if there is a time period in which the predicted electricity usage exceeds a predetermined value DE. The predicted electricity usage sometimes changes over time. The processing circuit 101 predicts the electricity usage for each predetermined time of the day. Therefore, the processing circuit 101 can predict the electricity usage more accurately than if the electricity usage were predicted the previous day. The power control system 10 can then connect the electric vehicle 20 to the charger 60 based on the more accurate prediction of electricity usage. This facilitates peak shaving and valley filling of the electricity used by the electric vehicle 20.

[0123] (1-4) The processing circuit 101 performs vehicle selection processing, which selects at least one electric vehicle 20 (i.e., the recommended vehicle 20RE) from among a plurality of electric vehicles 20 to be connected to the charger 60, and notification processing, which sends a connection request including a request to connect the recommended vehicle 20RE to the charger 60. When there are multiple electric vehicles 20, it is difficult to know which of the multiple electric vehicles 20 should be connected to the charger 60. The aforementioned processing circuit 101 selects the electric vehicle 20 to be connected to the charger 60 from among the multiple electric vehicles 20. Therefore, the power control system 10 can alleviate the burden of selecting the electric vehicle 20 to be connected to the charger 60 from among the multiple electric vehicles 20.

[0124] (1-5) In the case where multiple electric vehicles 20 include at least one plug-in hybrid vehicle 21 and at least one electric vehicle 22, the processing circuit 101 selects the plug-in hybrid vehicle 21 as the recommended vehicle 20RE. If a discharge operation is performed, the electrical power stored in the battery 33 of the electric vehicle 20 gradually decreases. If the electrical power stored in the battery 33 reaches a predetermined lower limit, the electric vehicle 22 in the electric vehicle 20 will be unable to operate. On the other hand, the plug-in hybrid vehicle 21 in the electric vehicle 20 can also operate by burning fuel even when the electrical power stored in the battery 33 reaches the predetermined lower limit. Since the power control system 10 selects the plug-in hybrid vehicle 21 as the recommended vehicle 20RE, it can suppress the situation where the electric vehicle 20 cannot operate due to the electrical power stored in the battery 33 reaching the predetermined lower limit.

[0125] (1-6) When multiple chargers 60 exist within facility 50, it is difficult to determine which charger 60 to connect the electric vehicle 20 to. Processing circuit 101 performs charger selection processing to select at least one charger 60 from the multiple chargers 60 to connect to the electric vehicle 20, i.e., a recommended charger 60RE. Processing circuit 101 performs a connection request notification processing, including a request to connect the electric vehicle 20 to the recommended charger 60RE. Thus, the power control system 10 can alleviate the burden of selecting the charger 60 to connect to the electric vehicle 20 from the multiple chargers 60.

[0126] (1-7) The plurality of chargers 60 includes at least two chargers 60 that can supply different amounts of power from the electric vehicle 20 to the facility 50 during the discharge operation. If the electric vehicle 20 is connected to a charger 60 that can supply less power from the electric vehicle 20 to the facility 50, there is a possibility that the power used exceeds a predetermined value DE due to insufficient power supply to the facility 50. The processing circuit 101 selects the charger 60 that can supply the most power from the electric vehicle 20 to the facility 50 as the recommended charger 60RE. As a result, the power control system 10 is able to suppress the occurrence of insufficient power supply from the electric vehicle 20 to the facility 50.

[0127] (1-8) The power control system 10 notifies the information processing terminal 104 located in the facility 50 of a connection request. For example, the power control system 10 may notify the administrator of the facility 50 of a connection request that enables the electric vehicle 20, which supplies power to the facility 50, to connect to the charger 60.

[0128] (1-9) Facility 50 is an office. The power control system 10 notifies the staff of the office of a connection request via a portable information processing terminal 300. The power control system 10 can notify the staff of facility 50 of a connection request that enables the electric vehicle 20, which supplies power to facility 50, to connect to the charger 60.

[0129] (1-10) The power control system 10 notifies the portable information processing terminal 300 held by the manager of the electric vehicle 20 of a connection request. The power control system 10 can notify the manager of the electric vehicle 20 of a connection request that enables the electric vehicle 20, which is capable of supplying power to the facility 50, to connect to the charger 60.

[0130] (1-11) The power control system 10 notifies the information processing terminal 35 installed on the electric vehicle 20 of a connection request. Thus, the power control system 10 can notify the user operating the electric vehicle 20 of a connection request that enables the electric vehicle 20, which is capable of supplying power to the facility 50, to connect to the charger 60.

[0131] (1-12) The power control system 10 notifies the information processing terminal 35 installed on the recommended vehicle 20RE of a connection request. Thus, the power control system 10 can notify the user operating the recommended vehicle 20RE of a connection request that enables the electric vehicle 20, which is capable of supplying power to the facility 50, to connect to the charger 60.

[0132] (1-13) The power control method executed by the power control system 10 includes the step of processing circuit 101 predicting the power consumption at each predetermined time (S11, S21). The power control method executed by the power control system 10 includes the step of notifying a connection request (S15, S25) when any of the predicted power consumption at each predetermined time exceeds a predetermined value DE, the connection request being a request to connect the electric vehicle 20, which is capable of supplying power to facility 50, to charger 60. By executing such a power control method, the power control system 10 prompts the connection of the electric vehicle 20, which is capable of supplying power to facility 50, to charger 60 when any of the predicted power consumption exceeds the predetermined value DE. Thus, peak shaving and valley filling of the power used by electric vehicle 20 can be easily achieved.

[0133] (1-14) The storage device 102 of the server 100 of the power control system 10 stores a power control program that causes the processing circuit 101 to perform processing. The power control program causes the processing circuit 101 to perform prediction processing to predict the power consumption for each predetermined time. If any of the predicted power consumption for each predetermined time exceeds a predetermined value DE, the power control program performs a notification processing to notify a connection request, which is a request to connect the electric vehicle 20, which can supply power to the facility 50, to the charger 60. According to the power control program described above, the power control system 10 can cause the electric vehicle 20, which can supply power to the facility 50, to connect to the charger 60 if any of the predicted power consumption for each predetermined time exceeds the predetermined value DE. Thus, peak shaving and valley filling of the power used by the electric vehicle 20 can be easily achieved.

[0134] <Example of a modification to the first embodiment>

[0135] The first embodiment can be modified as follows. The above-described first embodiment and the following modifications of the first embodiment can be combined and implemented with each other within the scope of technical non-contradiction.

[0136] • The processing circuit 101 can also perform forecasting processing simultaneously, predicting power consumption for each predetermined time of the day and predicting power consumption for each predetermined time of the next day. Specifically, the processing circuit 101 can perform forecasting processing simultaneously... Figure 3 The series of processes and Figure 7 The series of processes shown.

[0137] like Figure 10 As shown, the processing circuit 101 executes at time "T5" on day "A". Figure 3 The processing of S11 shown and Figure 7 The processing described in S21 is as follows. Therefore, the processing circuit 101 obtains the time series variation prediction load curve P3 representing the predicted electricity consumption for each predetermined time after time "T5" on day "A". During the periods from time "T6" to time "T7" and from time "T8" to time "T9", the predicted electricity consumption exceeds the predetermined value DE. In this case, the processing circuit 101 performs... Figure 3 The notification processing of the first connection request shown in the figure (S15) and Figure 7 The notification processing of the second connection request is shown in S25.

[0138] like Figure 11 As shown, after being notified Figure 3 The first connection request shown and Figure 7 The monitor 104M of the information processing terminal 104 shown in the second connection request displays the third request image IM3.

[0139] The third request image IM3 is an example of an image that prompts the connection of the electric vehicle 20 to the charger 60 on the same day and the following day. The third request image IM3 is also displayed on the monitor 300M of the portable information processing terminal 300, which has been notified of the first connection request and the second connection request, and on the monitor 35M of the information processing terminal 35, which has been notified of the first connection request and the second connection request.

[0140] The third request image IM3 contains the date and time of multiple days for connecting the recommended vehicle 20RE to the recommended charger 60RE. Specifically, the third request image IM3 displays the date and time of the day on which the processing circuit 101 notified the first connection request and the second connection request, and the date and time of the day after the day on which the processing circuit 101 notified the first connection request and the second connection request. The third request image IM3 also includes the number of recommended vehicles 20RE for each day.

[0141] The third request image IM3 contains the eighth image IP8, the ninth image IP9, the tenth image IP10, the eleventh image IP11, the twelfth image IP12, the thirteenth image IP13, and the fourteenth image IP14.

[0142] Part 8 Image IP8 and Figure 6 The first part of the image shown is the same as IP1, indicating the recommended vehicle 20RE for the second day. The ninth part of the image, IP9, is the same. Figure 6 The second part of the image, IP2, is the same, indicating the recommended charger 60RE for the next day. The tenth part of the image, IP10, indicates the time period during which the recommended vehicle 20RE shown in the eighth part of the image, IP8, will be electrically connected to the recommended charger 60RE shown in the ninth part of the image, IP9.

[0143] Part 11 Image IP11 and Figure 9 The fourth image shown is the same as IP4, indicating the recommended vehicle for that day, 20RE. The twelfth image, IP12, is the same. Figure 9 The fifth image, IP5, is the same as the recommended charger 60RE for that day. The thirteenth image, IP13, indicates the time period during which the recommended vehicle 20RE shown in the eleventh image, IP11, and the recommended charger 60RE shown in the twelfth image, IP12, will be electrically connected. The fourteenth image, IP14, is... Figure 9 The seventh part of the image shown is the same as IP7, indicating whether the recommended vehicle 20RE and the recommended charger 60RE connected to the recommended vehicle 20RE are electrically connected.

[0144] If the portion of the third request image IM3 that is displayed as "Confirmed" is selected, the third request image IM3 will no longer be displayed.

[0145] • Processing circuit 101 can also perform only Figure 3 The series of processes shown are Figure 7 This is one of a series of processes shown.

[0146] • The processing circuit 101 can also execute multiple times during a day. Figure 3 The series of processes shown.

[0147] • The processing circuit 101 can also execute multiple times during a day. Figure 7 The series of processes shown.

[0148] • The power consumption predicted by the processing circuit 101 is not limited to the power consumption for the next day. For example, the processing circuit 101 can also predict the power consumption for two days later. For example, the processing circuit 101 can predict the power consumption for one week later.

[0149] • Multiple electric vehicles 20 can also all be plug-in hybrid vehicles 21.

[0150] • Multiple electric vehicles 20 can also all be electric vehicles 22.

[0151] • The processing circuit 101 can also select electric vehicle 22 as recommended vehicle 20RE when there are multiple electric vehicles 20 including plug-in hybrid vehicle 21 and electric vehicle 22.

[0152] • The processing circuit 101 can also select the electric vehicle 20 with the most electric power stored in the battery 33 as the recommended vehicle 20RE.

[0153] • The processing circuit 101 may also not perform the processing of obtaining information on the amount of electricity stored in the batteries 33 of each of the multiple electric vehicles 20.

[0154] • If the processing circuit 101 notifies of a connection request, it may not perform the vehicle selection process of selecting the recommended vehicle 20RE. If the processing circuit 101 does not perform the vehicle selection process of selecting the recommended vehicle 20RE, the connection request will not include a request to connect the recommended vehicle 20RE to the charger 60.

[0155] • The processing circuit 101 can also select a charger 60 other than the charger 60 that can supply the most power from the electric vehicle 20 to the facility 50 as the recommended charger 60RE.

[0156] • The processing circuit 101 may also not perform the processing of obtaining information on the power that each of the chargers 60 can supply from the electric vehicle 20 to the facility 50.

[0157] • If the processing circuit 101 notifies of a connection request, it may not perform the charger / discharger selection process of selecting the recommended charger / discharger 60RE. If the processing circuit 101 does not perform the charger / discharger selection process of selecting the recommended charger / discharger 60RE, the connection request will not include a request to connect the electric vehicle 20 to the recommended charger / discharger 60RE.

[0158] (Second Implementation)

[0159] The following is for reference Figure 3 , Figure 7 as well as Figure 12 The power control system according to the second embodiment will be described below. The description will focus on the differences from the first embodiment. Points identical to those in the first embodiment will be simplified or omitted in the description.

[0160] In the second embodiment, in Figure 3 S13 and shown Figure 7 The reference for selecting the recommended vehicle 20RE and the recommended charger 60RE in the processing of S23 shown is different from that in the first embodiment.

[0161] exist Figure 3 S13 and shown Figure 7 In S23 shown, the processing circuit 101 of the second embodiment selects a recommended vehicle 20RE in a manner that minimizes the number of electric vehicles 20 connected to the charger 60. That is, the processing circuit 101 selects at least one recommended vehicle 20RE in a manner that minimizes the number of recommended vehicles 20REs required to achieve the required electric power.

[0162] Reference Figure 12 The following explanation addresses the situation where, in order to prevent the electrical power used by facility 50 from exceeding the predetermined value DE, it is necessary to supply 6kW of electricity from electric vehicle 20 to facility 50 for 3 hours.

[0163] Processing circuit 101 in Figure 3 S13 and shown Figure 7 In the process shown in S23, from Figure 12 Among the plug-in hybrid vehicle 21A, plug-in hybrid vehicle 21B, and electric vehicle 22A shown, vehicle 20RE is selected as the recommended vehicle. The plug-in hybrid vehicle 21A has a battery capacity of 12 kWh stored in its battery 33. The plug-in hybrid vehicle 21B also has a battery capacity of 12 kWh stored in its battery 33. The electric vehicle 22A has a battery capacity of 72 kWh stored in its battery 33.

[0164] Processing circuit 101 in Figure 3 S13 and shown Figure 7 In the process shown in S23, from Figure 12 Among the chargers 60C, 60D, and 60E shown, charger 60RE is recommended. Charger 60C can supply 3kW of power from electric vehicle 20 to facility 50. Charger 60D can also supply 3kW of power from electric vehicle 20 to facility 50. Charger 60E can supply 6kW of power from electric vehicle 20 to facility 50.

[0165] Several modes exist for supplying power to facility 50 to prevent its power consumption from exceeding a predetermined value DE. For example, such as... Figure 12 As shown, the first method involves electrically connecting the plug-in hybrid vehicle 21A to the charger 60C and the plug-in hybrid vehicle 21B to the charger 60D, as indicated by the dashed lines. In the first method, after 3 hours from the start of the discharge operation, the electrical energy stored in the battery 33 of the plug-in hybrid vehicle 21A is 3 kWh. In the first method, after 3 hours from the start of the discharge operation, the electrical energy stored in the battery 33 of the plug-in hybrid vehicle 21B is also 3 kWh. Therefore, when the processing circuit 101 selects the first method, even after power is supplied to the facility 50, each electric vehicle 20 can achieve operation based on the motor 30 by consuming the electrical energy stored in the battery 33.

[0166] For example, the second method is to electrically connect the electric vehicle 22A to the charger 60E, as shown by the solid line. In the second method, after 3 hours from the start of the discharge operation, the electric vehicle 22A has 54 kWh of electricity stored in the battery 33. Therefore, when the processing circuit 101 selects the second method, each electric vehicle 20 can also achieve driving based on the motor 30 by consuming the electricity stored in the battery 33.

[0167] Processing circuit 101 selects recommended vehicle 20RE in a manner that minimizes the number of electric vehicles 20 connected to charger 60. Therefore, as for the connection method between the electric vehicle 20 and charger 60, processing circuit 101 selects the second method between the first and second methods. That is, processing circuit 101... Figure 3 S13 and shown Figure 7 In the process shown in S23, electric vehicle 22A is selected as recommended vehicle 20RE, and charger 60E is selected as recommended charger 60RE.

[0168] The power control system 10 may also include a charger 60 with multiple charging plugs 61. In this case, the processing circuit 101 further selects a recommended charger 60RE in such a way that the number of chargers 60 connected to the electric vehicle 20 is minimized. That is, the processing circuit 101 selects at least one recommended charger 60RE in such a way that the number of recommended chargers 60REs required to achieve the required electrical power is minimized.

[0169] <The Role of the Second Embodiment>

[0170] If the predicted power consumption at any given time exceeds a predetermined value DE, the power control system 10 prompts the electric vehicle 20 capable of supplying power to facility 50 to connect to charger 60. The processing circuit 101 selects recommended vehicle 20RE to minimize the number of electric vehicles 20 connected to charger 60.

[0171] <Effects of the Second Implementation>

[0172] In the configuration of the second embodiment, the same effects as those of (1-1) to (1-4), (1-6), and (1-8) to (1-14) of the first embodiment can be obtained. In addition, the following effects can also be obtained in the configuration of the second embodiment.

[0173] (2-1) The power control system 10 can reduce the number of electric vehicles 20 that cannot be used as a mobility mechanism.

[0174] (2-2) Chargers 60 already connected to electric vehicles 20 cannot be used for charging other electric vehicles 20. The processing circuit 101 selects a recommended charger 60RE in a manner that minimizes the number of chargers 60 connected to electric vehicles 20 among the multiple chargers 60. As a result, the power control system 10 is able to reduce the number of chargers 60 that cannot be used for charging operations.

[0175] <Example of a modification to the second embodiment>

[0176] The second embodiment can be modified as follows. The above-described second embodiment and the following modifications of the second embodiment can be combined and implemented with each other within the scope of technical non-contradiction.

[0177] • The processing circuit 101 can also select the recommended vehicle 20RE in a manner that minimizes the number of plug-in hybrid vehicles 21 connected to the charger 60.

[0178] • The processing circuit 101 can also select the recommended vehicle 20RE in a manner that minimizes the number of electric vehicles 22 connected to the charger 60.

[0179] (Third implementation method)

[0180] The following is for reference Figures 13-16 The power control system according to the third embodiment will be described below. The description will focus on the differences from the first embodiment. Points identical to those in the first embodiment will be simplified or omitted in the description.

[0181] In the first embodiment, the power control system 10 determines whether to notify a connection request based on the predicted power consumption at each predetermined time. Alternatively, in the third embodiment, the processing circuit 101 determines whether to notify a connection request based on the current power consumption obtained from the fuel meter 55.

[0182] <Notification based on the obtained connection request for the use of electrical power>

[0183] The processing circuit 101 repeatedly executes a series of processes based on the current power consumption obtained from the fuel gauge 55 to determine whether to notify a connection request at a predetermined period. The processing circuit 101 may also execute this series of processes at a predetermined time.

[0184] like Figure 13 As shown, if this series of processes begins, in process S30, the processing circuit 101 obtains the current power consumption from the power meter 55. Then, the processing circuit 101 causes the process to proceed to S31. The current power consumption is the power consumption over a predetermined time period calculated based on the most recent power consumption.

[0185] In the processing of S31, the processing circuit 101 determines whether the obtained power usage exceeds the threshold TH. The threshold TH is a value smaller than the predetermined value DE.

[0186] If the obtained power consumption exceeds the threshold TH (S31: Yes), the processing circuit 101 initiates the processing step S32. If the obtained power consumption does not exceed the threshold TH (S31: No), the processing circuit 101 temporarily terminates. Figure 13 The series of processes shown.

[0187] like Figure 14 As shown, when the processing circuit 101 executes the processing of S31 at time "T10", since the obtained power consumption does not exceed the threshold TH (S31: No), the processing circuit 101 temporarily terminates. Figure 13 The series of processes shown. When the processing circuit 101 executes the process S31 at time "T11", since the obtained power consumption exceeds the threshold TH (S31: Yes), the processing circuit 101 initiates the processing. Figure 13 S32 is shown.

[0188] In the S32 processing, processing circuit 101 and Figure 3 The process shown in S13 is the same, obtaining the information needed to select the electric vehicle 20 connected to the charger 60, i.e., the recommended vehicle 20RE, from among the multiple electric vehicles 20. In addition, in the process of S32, the processing circuit 101 and... Figure 3The process in S13 is the same as shown, obtaining the information needed to select the recommended charger 60 (i.e., the recommended charger 60RE) from among the plurality of chargers 60 to connect to the recommended vehicle 20RE. Furthermore, the processing circuit 101 also obtains information from the storage device 102 indicating whether each of the plurality of chargers 60 can be connected to the electric vehicle 20. The processing circuit 101 also obtains information from the storage device 102 determining the combination of the connected charger 60 and the electric vehicle 20. Then, the processing circuit 101 proceeds to S33.

[0189] In the S33 process, the processing circuit 101 determines whether there is a charger 60 among the plurality of chargers 60 that can be connected to the electric vehicle 20.

[0190] If one of the multiple chargers 60 is a charger 60 that can be connected to the electric vehicle 20 (S33: Yes), the processing circuit 101 causes the processing to proceed to S34.

[0191] If there is no charger 60 that can be connected to the electric vehicle 20 (S33: No), the processing circuit 101 is temporarily terminated. Figure 13 The series of processes shown.

[0192] In the process of S34, the processing circuit 101 performs a vehicle selection process to select at least one electric vehicle 20, i.e., a recommended vehicle 20RE, from among the plurality of electric vehicles 20 that is connected to the charger 60. In addition, in the process of S34, the processing circuit 101 performs a charger selection process to select at least one recommended charger 60RE from among the chargers 60 that can be connected to the electric vehicle 20.

[0193] The processing circuit 101 of the third embodiment selects the electric vehicle 20 with the highest stored electric power in its battery 33 from among the multiple electric vehicles 20 as the recommended vehicle 20RE based on information stored in the storage device 102. The storage device 102 stores the electric power stored in the battery 33 of each of the multiple electric vehicles 20.

[0194] like Figure 15 As shown, the case of a plug-in hybrid vehicle 21 with 12 kWh of stored power in battery 33 and an electric vehicle 22 with 72 kWh of stored power in battery 33 will be described. In this case, the processing circuit 101 selects the electric vehicle 22, which has the most stored power in battery 33, as the recommended vehicle 20RE. Then, the processing circuit 101 initiates processing S35.

[0195] In the S35 process, the processing circuit 101 executes a notification process for a third connection request to connect the recommended vehicle 20RE to the recommended charger 60RE as a connection request. Then, the processing circuit 101 terminates. Figure 13 The series of processes shown.

[0196] <Image showing the connection between the electric vehicle 20 and the charger 60>

[0197] like Figure 16 As shown, a fourth request image IM4 is displayed on the monitor 104M of the information processing terminal 104 that has been notified of the third connection request. The fourth request image IM4 is an example of an image prompting the connection of the electric vehicle 20 to the charger 60. The fourth request image IM4 is also displayed on the monitor 300M of the portable information processing terminal 300 that has been notified of the third connection request, and on the monitor 35M of the information processing terminal 35 that has been notified of the third connection request. The fourth request image IM4 contains the recommended number of vehicles 20RE.

[0198] The fourth request image IM4 contains the fifteenth image IP15, the sixteenth image IP16, and the seventeenth image IP17.

[0199] Part 15, image IP15, represents the recommended vehicle 20RE. Part 16, image IP16, represents the recommended charger 60RE. Part 17, image IP17, represents the time period during which the recommended vehicle 20RE shown in Part 15, image IP15, and the recommended charger 60RE shown in Part 16, image IP16, will be connected.

[0200] exist Figure 16 The fifteenth image IP15 shown depicts a first vehicle as the recommended vehicle 20RE. The display method of the fifteenth image IP15 is the same as that of the first image IP1. The fifteenth image IP15 may also display the identification information of the recommended vehicle 20RE. For example, the fifteenth image IP15 may display the numbers and symbols recorded on the license plate of the recommended vehicle 20RE.

[0201] exist Figure 16 The sixteenth image IP16 shown depicts a first charger / discharger as the recommended charger / discharger 60RE.

[0202] exist Figure 16 Image IP17, shown in section seventeen, indicates the period "~12:00" as the time period during which the first vehicle is connected to the first charger. "~12:00" refers to the period from the time the third connection request was notified until 12:00.

[0203] The fourth request image IM4 also includes an eighteenth image IP18 indicating whether the recommended vehicle 20RE and the recommended charger / discharger 60RE are electrically connected. The eighteenth image IP18 in the fourth request image IM4 is displayed in the same way as the seventh image IP7 in the second request image IM2. That is, when the recommended vehicle 20RE and the recommended charger / discharger 60RE are not electrically connected, the eighteenth image IP18 displays "Please connect the recommended vehicle". When the recommended vehicle 20RE and the recommended charger / discharger 60RE are electrically connected, the eighteenth image IP18 displays "OK".

[0204] exist Figure 16 In the example shown, the first vehicle is not electrically connected to the first charger. Therefore, in Part 18, image IP18 displays "Please connect the recommended vehicle".

[0205] If the portion of the fourth request image IM4 that is displayed as "Confirmed" is selected, the fourth request image IM4 will no longer be displayed.

[0206] <The Role of the Third Implementation>

[0207] When the current power consumption obtained exceeds the threshold TH, the processing circuit 101 prompts the electric vehicle 20, which is capable of supplying power to the facility 50, to be connected to the charger 60.

[0208] <Effects of the Third Implementation>

[0209] In the configuration of the third embodiment, the same effects as in the first embodiment can be obtained. In addition, the following effects can be obtained in the configuration of the third embodiment.

[0210] (3-1) Sometimes there is a deviation between the predicted power consumption and the actual power consumption. Even when there is a deviation between the predicted power consumption and the actual power consumption, the power control system 10 described above can still connect the electric vehicle 20 to the charger 60 based on the current power consumption. As a result, peak shaving and valley filling of the power used by the electric vehicle 20 can be easily achieved.

[0211] (3-2) When there is a charger 60 among the plurality of chargers 60 that can be connected to the electric vehicle 20, the processing circuit 101 performs notification processing to notify a connection request. When there is no charger 60 that can be connected to the electric vehicle 20, even if a connection request is notified, the electric vehicle 20 cannot be connected to the charger 60. The power control system 10 can suppress the occurrence of a connection request being notified even when there is no charger 60 that can be connected to the electric vehicle 20.

[0212] (3-3) The threshold TH is a value smaller than the predetermined value DE. Therefore, the processing circuit 101 notifies the connection request before the current power consumption reaches the predetermined value DE. Thus, the power control system 10 is able to cause the electric vehicle 20 to be connected to the charger 60 before the current power consumption reaches the predetermined value DE.

[0213] (3-4) During the discharge operation, if the electrical power stored in the battery 33 of the electric vehicle 20 reaches a predetermined lower limit, the discharge operation cannot continue. The processing circuit 101 performs a process to obtain information on the amount of electrical power stored in the batteries 33 of each of the multiple electric vehicles 20. The processing circuit 101 performs a process to select the electric vehicle 20 with the most electrical power stored in its batteries 33 as the recommended vehicle 20RE. As a result, the power control system 10 is able to suppress the situation where the discharge operation cannot continue.

[0214] <Example of a modification to the third embodiment>

[0215] The third embodiment can be modified as follows. The above-described third embodiment and the following modifications of the third embodiment can be combined and implemented with each other within the scope of technical non-contradiction.

[0216] • The threshold TH can be any value below the predetermined value DE. For example, the threshold TH can also be the same as the predetermined value DE.

[0217] Even if there is no charger 60 that can be connected to the electric vehicle 20 because the charger 60 has already been connected to the electric vehicle 20, the processing circuit 101 can still perform notification processing of the connection request when the power used exceeds the threshold TH.

[0218] • If, despite the electric vehicle 20 being connected to the charger 60, the power consumption exceeds the threshold TH, the power stored in the battery 33 of the electric vehicle 20 connected to the charger 60 may reach a predetermined lower limit. Therefore, as a notification process for a connection request, the processing circuit 101 may also perform a notification process for disconnecting the charger 60 from the electric vehicle 20 and for a request to connect the charger 60 to another electric vehicle 20.

[0219] <Other Change Examples>

[0220] Furthermore, as elements common to all the above embodiments and capable of being modified, there are the following elements. The following modifications can be combined and implemented within a technically compatible scope.

[0221] • The destination of the connection request notification from the power control system 10 can be appropriately changed. For example, the power control system 10 may not notify the information processing terminal 104 installed in facility 50 of the connection request. The power control system 10 may not notify the portable information processing terminal 300 held by the staff of facility 50 of the connection request. The power control system 10 may not notify the portable information processing terminal 300 held by the manager of electric vehicle 20 of the connection request. The power control system 10 may not notify the information processing terminal 35 installed in electric vehicle 20 of the connection request. The power control system 10 may not notify the information processing terminal 35 installed in recommendation vehicle 20RE of the connection request.

[0222] • Processing circuit 101 in Figure 3 The processing of S14 shown and Figure 7 In the process shown in S24, the electric vehicle 20 with the most electric power stored in the battery 33 among the multiple electric vehicles 20 can also be selected as the recommended vehicle 20RE.

[0223] • The case where there is one plug-in hybrid vehicle 21 and one electric vehicle 22 as multiple electric vehicles 20 will be described. If the electric power stored in the battery 33 of the electric vehicle 22 is greater than the electric power stored in the battery 33 of the plug-in hybrid vehicle 21, the processing circuit 101 may also select the electric vehicle 22 as the recommended vehicle 20RE.

[0224] • The processing circuit 101 may also be configured as a processing circuitry comprising one or more processors that perform various processes according to a computer program (software). Furthermore, the processing circuit 101 may also be configured as one or more dedicated hardware circuits, such as application-specific integrated circuits (ASICs), or combinations thereof, that perform at least a portion of the various processes. The processor includes a CPU and memories such as RAM and ROM. The memories store program code or instructions configured to cause the CPU to perform processes. Memory, or non-transitory computer-readable medium, includes all available media accessible by a general-purpose or special-purpose computer. Programs may also be stored on non-volatile data storage media that can be read by a computer, such as CD-ROMs, and distributed as program products. Programs may also be provided by information providers connected to networks such as the Internet as downloadable program products.
