  In the database 7, information (device information) related to backup devices provided in each of the plurality of facilities 10 includes, for each facility ID, the types of backup devices of the facilities 10 (for example, POS systems, lighting devices, and OA devices). Etc.), the rated power consumption of the backup device, and the emergency operation schedule are registered. As an operation schedule, for example, there is a time schedule of ON and OFF of the backup device.

  In addition, the database 7 includes information on automobiles 30 provided with the automobile control devices 31 for constructing the storage battery charging plan support system 1 in advance (car information) as car ID as individual identification information for each car 30. Is assigned and registered. Specifically, for each vehicle ID, the type of the vehicle 30 (for example, PHV (plug-in hybrid vehicle) or EV (electric vehicle)), and battery capacity information of the in-vehicle storage battery 32 included in the vehicle 30 The charging output information to the backup storage battery 12 of the in-vehicle storage battery 32 of the automobile 30 is registered. In the present embodiment, the vehicle control device 31 is provided in a plurality of vehicles 30, and each vehicle control device 31 constructs the storage battery charging plan support system 1. However, the present invention is not limited to this. A single automobile control device 31 provided in one automobile 30 may be used.

  Next, with reference to FIG.4 and FIG.5, operation | movement of the storage battery charge plan assistance system 1 of a present Example is demonstrated. FIG. 4 is a sequence diagram of each control device, and FIG. 5 is a flowchart of the facility control device 11. When a power failure occurs in any of the facilities 10, the control unit 19 of the facility control device 11 provided in the facility 10 is installed in the facility 10 from the backup storage battery 12 provided in the facility 10 in step S1. The backup operation to supply power to the backup device is started.

  In step S <b> 2, the control unit 19 transmits information related to the occurrence of a power failure including the facility ID of the facility 10 and the power failure start time to the charging support control device 2 via the network 21 by the communication unit 20. In step S <b> 3, the control unit 19 causes the communication unit 20 to connect the charging support control device 2 via the network 21 with the facility ID of the facility 10, the current time, and the current backup battery 12 of the facility 10. Send information about remaining battery power.

  On the other hand, the charging support control device 2 receives information on the occurrence of a power outage including the facility ID, the power outage start time, the current time, and the (current) backup storage battery 12 at that time from each facility 10 where the power outage occurred. When the facility power outage information including the information regarding the remaining battery level is received, the facility power outage information from each facility 10 is registered in the database 7 in step S11. In addition, you may request | require the battery residual amount information of the backup storage battery 12 of the said facility 10 from the charge assistance control apparatus 2 with respect to the facility control apparatus 11 which received the facility power failure information. In this case, the control unit 19 of the facility control device 11 transmits the remaining battery level information at that time in response to a request from the charging support control device 2.

  FIG. 5A shows, as an example, a data table of information regarding the power outage start time (June 15, 2011 0:00) of the facility IDs 1 to 3 created in the database 7. FIG. 5B shows, as an example, a data table of information regarding the remaining battery level and the time when the information regarding the remaining battery level is received for each facility ID created in the database 7. In this case, in the facility ID1, the remaining battery capacity of the backup storage battery 12 of the facility ID1 is 16 kWh at 0:00 on June 15, 2011, and the facility ID1 is backed up at 19:00 on June 15, 2011. The battery remaining amount of the storage battery 12 is 12 kWh and the facility ID 2 has a battery remaining amount of 17 kWh at the backup storage battery 12 of the facility ID 2 at 0:00 on June 15, 2011. The information that the remaining battery capacity of the backup storage battery 12 of the facility ID 3 is 16 kWh at 0:00 is registered.

  Then, the charging support control device 2 proceeds to step S12, and determines the priority order for charging the backup storage battery 12 of each facility 10 that has transmitted the facility power failure information. The priority determination operation will be described with reference to FIGS. 6 is a flowchart of the priority order determining operation, FIG. 7 is a diagram illustrating calculation of changes in power consumption and power generation, FIG. 8 is a diagram illustrating an evaluation point table for determining priority, and FIG. FIG. 10 is a diagram showing a change in power consumption when the (area) is small, FIG. 10 is a diagram showing a change in power consumption when the power consumption change (area) is large, and FIG. 11 is a data table for determining priorities. FIG.

  First, in step S21, the control unit 3 of the charging support control device 2 includes a data table (information in FIG. 5 (FIG. 5) including each facility ID created in the database 7 and information related to the occurrence of a power failure including the corresponding power failure start time. A)), any one facility ID, in this case, the facility ID 1 is selected.

  And it progresses to step S22 and the control part 3 of the charge assistance control apparatus 2 is connected to the backup storage battery 12 of the said facility 10 based on the information regarding each backup storage battery 12 of each facility 10 previously registered in the database 7. Calculate and predict changes in the power consumption of backup devices. Further, when the auxiliary power generation device 18 is provided in the facility 10, the power generation amount of the auxiliary power generation device 18 is calculated and predicted.

  Specifically, the control unit 3 reads out device information registered for the facility ID 1 from the database 7. In FIG. 3, the backup devices for the facility ID 1 are the POS system 13 and the lighting device 14. The POS system 13 has a rated power consumption of 200 W, and the operation schedule is all day long. Therefore, as shown in the bottom of FIG. 7, the transition of the integrated value of the power consumption of the POS system 13 increases by 200 Wh per hour from 0:00 to 24:00. The lighting device 14 has a rated power consumption of 1 kW, and the operation schedule is ON from 0:00 to 7:00, OFF from 7:00 to 19:00, and ON from 19:00 to 7:00 on the next day. Therefore, as shown in the middle part of FIG. 7, the transition of the integrated value of the power consumption of the lighting device 14 increases by 1 kWh per hour from 0 o'clock to 7 o'clock and remains unchanged from 7 o'clock to 19 o'clock. From 19:00 to next 7 o'clock, it increases by 1 kWh per hour. By adding the change in the power consumption of the POS system 13 shown in the lowermost stage and the change in the power consumption of the lighting device 14 shown in the middle, the change in the power consumption of the backup device with the facility ID 1 can be predicted. .

  In addition, the control unit 3 reads information related to the backup storage battery 12 registered for the facility ID 1 from the database 7. In FIG. 3, the backup storage battery 12 for the facility ID 1 has an auxiliary power generation device 18, and the capacity (output) of the auxiliary power generation device 18 is 1 kW. In addition, the control unit 3 reads out the facility position information (location) of the facility ID 1 from the database 7 and also corresponds to the facility position information at that time (weather information such as sunny, cloudy, rain, solar radiation amount, wind direction) A power generation environment condition including wind speed) is acquired from an external weather forecast server via the network 21. And the solar radiation amount change of the day is estimated from the said power generation environmental condition, and the transition of the power generation amount of the day is predicted from the power generation amount with respect to the solar radiation amount by the auxiliary power generation device 18.

  And control part 3 amends prediction (power consumption change information) of change of the power consumption of the backup equipment of the above-mentioned facility ID1 from change prediction of the amount of power generation by auxiliary power generation device 18 acquired in step S22 in step S23. To do.

  Thereafter, in step S24, the control unit 3 acquires the current time corresponding to the facility ID 1 registered in the database 7 and information regarding the remaining battery level of the backup storage battery 12 at the time, and the remaining battery level at that time. Based on the change prediction of the power consumption of the backup device corrected with the power generation amount as described above, the power consumption change information of the backup storage battery 12 is predicted, thereby eliminating the remaining battery capacity of the backup storage battery 12. Or, the remaining time of zero until it is not practically used is predicted. On the right side of FIG. 7, the remaining battery capacity of the backup storage battery 12 at 0:00 is 16 kWh. Based on the change prediction (power consumption change information) of the backup storage battery 12 acquired as described above. The power consumption change (area) of the backup storage battery 12 and the remaining zero time of the backup storage battery 12 are predicted by calculation. In this case, the remaining zero time is 29 hours, and the power consumption change (area) is 300 kWh · h.

  The change in power consumption (area) is the area (time integrated value of the remaining power of the storage battery) surrounded by the curve of the remaining power of the storage battery and the time axis, and is related to the time change of the power consumption speed of the storage battery. It is the value. In other words, when this area is small, the power consumption speed is large in the early time zone (the first half of the battery power consumption), and the power consumption speed is small in the late time zone (the second half of the battery power consumption). It means power consumption pattern. In addition, when this area is large, the power consumption speed is small in the early hours (the first half of the power consumption of the storage battery), and the power consumption speeds are large in the late time (the second half of the power consumption of the storage battery). It means power consumption pattern.

  Further, the importance level of the backup storage battery 12 of the facility ID 1 is the importance level because the purpose of use of the backup storage battery 12 is for a store having a POS system as registered in the importance level table of the database 7. A.

  Here, the database 7 includes an evaluation point table for determining priorities as shown in FIG. 8 in advance, which relates to the zero remaining time of the backup storage battery 12 and changes in power consumption (area) of the backup storage battery 12. ) And importance.

  In FIG. 8, as an example, regarding the zero remaining time of the backup storage battery 12, it is 1 point when the remaining time is longer than 24 hours, 2 points when longer than 21 hours and within 24 hours, and longer than 18 hours. 3 points if it is within 21 hours, 4 points if it is longer than 15 hours and within 18 hours, ... 9 points if it is longer than 1 hour and within 3 hours, 10 points if it is within 1 hour Yes. As described above, the shorter the remaining time is, the faster it is necessary to charge the battery, so the evaluation score is set higher.

  Regarding the power consumption change (area) of the backup storage battery 12, 1 point is greater than 900 kWh · h, 2 points when greater than 800 and within 900 kWh · h, and 3 points when greater than 700 and within 800 kWh · h. , More than 600 and within 700 kWh · h, 4 points,..., More than 100 and within 200 kWh · h, 9 points, and within 100 kWh · h, 10 points.

  As shown in FIG. 9, the backup storage battery 12 with a small power consumption change (area) is expected to consume power at an earlier time. As shown in FIG. 10, the backup storage battery 12 having a large power consumption change (area) is predicted to consume power at a later time. When performing the prediction calculation of the power consumption of the backup storage battery 12, in consideration of the possibility that a prediction error occurs and the remaining battery power is lost, the backup storage battery that consumes power at an earlier time is: Since it is necessary to charge at an earlier stage, the evaluation score is set higher.

  Regarding the importance of the backup storage battery 12, the importance A is 10 points, the importance B is 8 points, the importance C is 6 points, the importance D is 4 points, and the importance E is Two points are given in the case. Thus, it sets so that an evaluation point may become high, so that importance is high.

  For the facility ID1 in this example, the zero remaining time of the backup storage battery 12 is 29 hours, so the evaluation point for the remaining zero time is 1 point, and the power consumption change (area) is 300 kWh · h. Therefore, since the evaluation score regarding the power consumption change (area) is 8 points and the importance is A, the evaluation score regarding the importance is 10 points. Therefore, these total points of the facility ID 1 used for determining the charging priority are 19 points. In addition, the control unit 3 is registered in the data table in association with the remaining time of zero for the facility ID1, the power consumption change (area), the importance, and the total score calculated based on these. Yes.

  And the control part 3 progresses to step S25, and all the facilities registered in the data table ((A) of FIG. 5) which consists of each facility ID of the database 7, and the information regarding the occurrence of a power failure corresponding to the power failure start time corresponding to it. It is determined whether or not the operation has been performed on the facility 10, and thereafter, information on the occurrence of a power failure is transmitted, and a comprehensive point for determining the priority order for all the facilities 10 registered in the data table is acquired.

  As shown in FIG. 11, the control unit 3 stores the remaining zero time and the change in power consumption (area) for each facility ID as shown in FIG. ), The degree of importance, and the data table in which the total score calculated based on these values is registered, and these are compared, and the priority order is determined in descending order of the total score. Thereby, a charge required facility is determined based on a priority.

  In this embodiment, the control unit 3 performs charging based on the importance level information of the backup storage battery 12 of each facility 10, the power consumption change information, and the remaining time zero time information held in the database 7. Although the priority order is determined, the priority order is not limited to this, and priority is given to any one of these importance information, power consumption change information, and remaining time zero time information, or a combination thereof. The order may be determined.

  Next, returning to the flowchart of FIG. 4, the process proceeds from step S12 to step S13. In step S13, the control unit 3 of the charging support control device 2 requests vehicle information including vehicle position information of the vehicle control device 31 of each vehicle 30 registered in the database 7 (driving information collection request). On the other hand, as shown in the flowchart of FIG. 12, the vehicle control device 31 receives a request for vehicle information including vehicle position information in step S31. In step S32, the control unit 34 is acquired from the GPS interface. The current traveling position of the vehicle 30 is transmitted to the charging support control device 2 as vehicle position information. In this case, the vehicle position information may be GPS position information including longitude and latitude, or position information (address information) converted from the GPS position information by a built-in navigation system. In addition to this, the driver of the car 30 may transmit the position information as data to the charging support control device 2 by another device such as a mobile phone.

  As a result, in the charging support control device 2, the vehicle location information that is the current travel location is registered in the database 7 for each assigned vehicle ID based on the vehicle location information transmitted from each vehicle control device 31. FIG. 12C shows a data table of vehicle position information of vehicle IDs 1 to 3 created in the database 7 as an example. In the present embodiment, the vehicle position information of each automobile 30 is collected only at the time of a power failure of the facility 10, but the present invention is not limited to this, and the automobile position information may always be collected at regular intervals. .

  Further, the vehicle information may include information regarding the remaining battery level of the in-vehicle storage battery 32 of the vehicle 30. Normally, depending on the type of the vehicle 30, in the case of PHV, the remaining battery level of the in-vehicle storage battery 32 can be estimated to be almost fully charged by the electric power obtained by the regenerative brake. This is because the remaining battery capacity of the in-vehicle storage battery 32 varies greatly depending on the situation. Therefore, when the type of the vehicle registered for each vehicle ID based on the database 7 of the charging support control device 2 is EV, the vehicle information including information on the remaining battery level of the in-vehicle storage battery in addition to the vehicle position information. May be requested from the automobile control device 31.

  Then, returning to the flowchart of FIG. 4, the charging support control device 2 determines whether or not there is an automobile that can be currently used in step S <b> 14. That is, if no vehicle position information is transmitted from any of the vehicle control devices 31, it is determined that there is no currently available vehicle 30, and the process returns to step S13. If it is determined in step S14 that there is a car 30 that can be used currently, the process proceeds to step S15, and the charging plan operation (car scheduling determination operation) of each backup storage battery 12 by the car 30 is executed.

  The charging plan operation will be described with reference to the flowchart of FIG. First, in step S41, the control unit 3 of the charging support control device 2 selects a facility requiring charging based on the priority order determined in step S12. That is, in order to determine charging plans in order from the highest priority, the charging facilities are selected in order from the facility 10 having the highest priority. In this embodiment, as shown in FIG. 11, the facility ID 1 having the highest priority is selected first, but in the following description, a charging plan for the facility ID 3 is shown to facilitate understanding.

  And it progresses to step S42, and since the control part 3 determines the motor vehicle 30 which should be guide | induced to the charge required facility based on a priority, the vehicle 30 of the nearest distance to the charge required facility (facility ID3) based on the said priority order is. Which vehicle ID is selected is selected based on the facility location information of the facility ID 3 registered in the database 7 and the data table of the vehicle location information for the vehicle ID created in the database 7. In the present embodiment, the car 30 to be guided is determined to be the car 30 closest to the charging facility, but is not limited to this. For example, the travel time to the charging facility is, for example, The short car 30 may be determined.

  It is assumed that the vehicle ID 12 is the vehicle closest to the facility ID 3 that is a charging required facility. The control unit 3 proceeds to step S43, and calculates the time required for the vehicle ID 12 to move to the facility ID 3 that is a charging required facility. In this case, the distance to the facility ID 3 is calculated from the facility position information of the facility ID 3 and the vehicle position information of the vehicle ID 12, and the average speed of the vehicle 30 is determined according to the type of road on which the vehicle is scheduled to run. The travel time to the charging facility is calculated from the distance and the average speed.

  For example, if the travel distance to the charging facility is 20 km and the average speed is calculated as 20 km / h, the travel time to the charging facility is predicted to be 1 hour. Here, assuming that the current time is 0:00 and the travel time is 1 hour, the estimated arrival time of the car at the facility ID 3 which is a facility requiring charging is predicted to be 1:00.

  Then, the control unit 3 proceeds to step S44, and predicts the remaining battery level of the backup storage battery 12 of the facility ID 3 when it arrives at the facility ID 3 that is the facility requiring charging of the vehicle ID 12. Specifically, in the above, the prediction is made from the device information of the backup device with the facility ID 3, the transition prediction information of the power generation amount of the auxiliary power generation device 18, the current time of the backup storage battery 12, and the remaining battery amount information at that time. The remaining battery level of the backup storage battery 12 at the estimated arrival time of the vehicle ID 12 is predicted based on the power consumption change information (the diagram on the right side of FIG. 7). In this embodiment, the backup storage battery 12 at the power failure information reception time (0:00) has a remaining battery capacity of 5 kWh, and the backup device from the power failure information reception time to the scheduled vehicle arrival time (0: 0 to 1:00). Power consumption of 1 kWh (the lighting device 14 is 1 kW per hour during the day), and the power generation amount of the auxiliary power generation device 18 is 0 (no auxiliary power generation device 18). Expected to be 4 kWh. FIG. 14 shows a change in the remaining battery level of the backup storage battery 12 with the facility ID 3.

  And the control part 3 is based on the charge output information of the motor vehicle (automobile ID12) which should be induced | guided | derived to a charging required facility (facility ID3) in step S45, and the battery capacity information of the backup storage battery 12 of a charging required facility (facility ID3). Then, the charging amount and charging time of the backup storage battery 12 by the automobile are calculated. Specifically, the charging output information previously registered for each vehicle ID in the database 7 and the battery capacity information of the backup storage battery 12 registered for each facility ID are read out. In this case, the charging output information of the automobile ID 12 is 3 kW, the storage battery capacity of the car is 9 kWh, and the battery capacity of the backup storage battery 12 of the facility ID 3 is 16 kW.

  Here, the battery capacity of the backup storage battery 12 of the facility ID 3 is predicted to be 4 kWh while the battery capacity at the scheduled arrival time of the vehicle is 16 kWh. Therefore, the chargeable amount of charge by the backup storage battery 12 is 12 kWh. The charging output of the vehicle ID 12 is 3 kW, and the change in power consumption of the backup device connected to the backup storage battery 12 of the facility ID 3 is 1 kW. The actual amount of charge from the automobile 30 to the backup storage battery 12 is 2 kWh per hour. Therefore, the control unit 3 sets the charging time from the vehicle 30 to 3 hours from the storage battery capacity and the charging output of the car 30, so that the backup storage battery 12 of the facility ID 3 is charged 6 kWh after 3 hours from the start of charging. As a result, the remaining battery level becomes 10 kWh.

  In this case, as shown in FIG. 15, when the charging of the backup storage battery 12 by the first vehicle 30 is completed, the chargeable amount based on the battery capacity of the backup storage battery 12 is still 6 kWh. Yes. Therefore, the control unit 3 proceeds to step S46, returns to step S42, and executes a charging plan operation by the second automobile 30 assuming that charging of the backup storage battery 12 of the charging facility is not completed.

  In the charging plan operation by the second vehicle 30 as well as the first vehicle, since the vehicle 30 to be guided is determined, the vehicle 30 closest to the charging facility (facility ID 3) based on the priority order is determined. Determine which car ID it is. At this time, the car 30 (car ID 12 in this case) for which car scheduling has already been determined is excluded.

  Then, the estimated arrival time of the selected second automobile 3 (in this case, automobile ID 15) is a time obtained by adding the charging time to the estimated arrival time of the first automobile. If the time required for the second car to travel to the charging facility is longer than the time when the first car is scheduled to arrive plus the charging time, the time required for the second car Calculated based on However, in this case, since the second vehicle 3 is also assumed to be close to the charging facility, it is assumed that it can move to the charging facility by the end of the first charging time. .

  In the present embodiment, the estimated arrival time of the first car 30 is 1:00 and the charging time is 3 hours, so the charging end time is 4:00. Accordingly, the estimated arrival time of the second car 30 is 4:00. The second vehicle 30 (vehicle ID 15) has 3 kW of charge output information registered in advance in the database 7 for each vehicle ID, and the storage battery capacity of the vehicle is 9 kWh. As in the case of the first unit, the change in power consumption of the backup device connected to the backup storage battery 12 of the facility ID 3 is 1 kW. The actual charge amount from the second vehicle 30 to the backup storage battery 12 is 2 kWh per hour. The control unit 3 sets the charging time from the vehicle 30 to 3 hours from the storage battery capacity and the charging output of the car 30, so that the backup storage battery 12 of the facility ID 3 is charged 6 kWh after 3 hours from the start of charging. The remaining battery capacity is 16 kWh.

  The remaining battery capacity of the backup storage battery 12 is compared with the battery capacity information of the backup storage battery 12 previously registered in the database 7 for each facility ID. In this case, the remaining battery capacity has reached the battery capacity. Since the third vehicle scheduling is unnecessary, the control unit 3 terminates the charging planning operation by the vehicle 30 to the charging required facility (facility ID 3) in step S46.

  At this time, as shown in FIG. 16, the control unit 3 stores the facility arrival scheduled time information, the vehicle ID information of the vehicle 30 to be charged, and the backup storage battery 12 for each facility ID whose charging plan operation has been completed in the database 7. The chargeable amount information and the charging time information in the facility by the automobile 30 are created.

  Then, returning to the flowchart of FIG. 4 described above, the control unit 3 of the charging support control device 2 charges the facility control device 11 of the facility 10 where the charging plan operation has ended based on the determined charging plan (car scheduling) by the car. Notifying that the planned operation has been completed, and transmitting the charging plan result. Thereby, the control unit 19 of the facility-side control device 11 receives the completion of the charging plan operation and displays the charging plan result as shown in FIG. 5D on the output unit 35 (step S4). ). Specifically, the charging plan result includes the scheduled arrival time of the automobile 30, the automobile ID of the automobile 30, the chargeable amount of the backup storage battery 12, and the charging time of the automobile 30.

  On the other hand, the control unit 3 of the charging support control device 2 charges each vehicle control device 31 of the vehicle 30 selected as the vehicle to be guided based on the determined charging plan (car scheduling) by the car, including guidance information. Send the plan result. Specifically, as shown in (E) of FIG. 12, information related to a charging facility that is specific guidance information, estimated arrival time information, and charging time information at the facility are transmitted. When the control unit 34 of the vehicle control device 31 receives the charging plan result (guidance information), the display unit 35 displays information related to the charging facility as shown in FIG. Display charging time information at the facility. In addition, the information regarding a chargeable facility may be a facility name, GPS position information including longitude and latitude, or facility address information. In any case, the control unit 34 of the car control device 31 can acquire the position information of the facility requiring charging by the navigation system built in the car control device 31.

  Then, the control unit 34 of the automobile control device 31 sets the destination of the existing navigation system as the position information of the charging facility, based on the position information of the charging facility, and the route from the current position to the charging facility and the required Time etc. are displayed on the display part 35 and the said motor vehicle 30 is induced | guided | derived to a charge required facility.

  Upon receiving the guidance information, the driver of the car 30 heads for the charging facility according to the guidance information, and after the arrival of the charging facility, starts to charge the backup storage battery 12 of the charging facility from the in-vehicle storage battery 32. To do. In this case, charging is performed for a specified time.

  On the other hand, at the facility requiring charging, the guided vehicle 30 arrives and charging is executed for a predetermined time, thereby completing the charging. After the end of charging, the facility control device 11 of the facility 10 proceeds to step S5, determines whether or not the power failure continues, and if it continues, proceeds to step S3 to make a new charging request. The facility ID, the current time, and the remaining battery level information of the backup storage battery 12 at that time are transmitted to the charging support control device 2. In step S5, when the power failure has ended, the control is ended.

  Then, in step S15 of the flowchart of FIG. 4, the charging support control device 2 transmits the charging plan result to the facility control device 11 and the vehicle control device 31, and then proceeds to step S16 where all the information related to the occurrence of the power failure is transmitted. It is determined whether or not the charging plan for the facility 10 has been completed. If the charging plan has not been completed, the process proceeds to step S14 and, as before, charging is performed for other charging-required facilities corresponding to the next priority order. Make a plan. When charging results are obtained at a plurality of charging facilities, as shown in FIG. 17, the control unit 3 for each facility ID, the facility arrival time information, the vehicle ID information of the vehicle 30 to be charged, A data table of chargeable amount information of the backup storage battery 12 and charging time information in the facility by the automobile 30 is created.

  After completing the charging plan for all the facilities requiring charging, the charging support control device 2 proceeds to step S17, determines whether or not the power outage continues in any facility, and if it continues, In step S11, if the power failure is resolved, the control is terminated.

  Thus, according to the present embodiment, when a power failure occurs, the automobile 30 having the in-vehicle storage battery 32 can be guided in order from the facility 10 in which the backup storage battery 12 having a high priority is provided. Therefore, even when a power outage occurs in a plurality of facilities 10 at a time due to the occurrence of a natural disaster or the like, it is possible to charge the backup storage battery 12 efficiently and effectively based on the priority order. Each backup device can be operated according to 12 situations.

  Further, in this embodiment, for each of a plurality of charging facilities, a plurality of vehicles 30 are charged based on the priority order of the backup storage batteries 12 of each charging facility, and each facility control device determined is determined. 11 and the vehicle control device 31 are transmitted with the result of the charging plan, it is possible to charge the backup storage battery 12 more efficiently based on the priority order. In particular, the guided vehicle 30 transmits the guidance information to the charging facility in order from the closest to the charging facility with higher priority, so the vehicle 30 equipped with the in-vehicle storage battery 32 is required more efficiently. It is possible to guide to the charging facility.

  Further, when determining the priority, the facility power failure information includes information on the remaining battery level of the backup storage battery 12 of the facility. The priority order can be determined, and charging can be performed at an appropriate timing for each backup storage battery 12.

  Similarly, since the change in power consumption of the backup storage battery 12 is predicted based on the device information and the priority order is determined based on the predicted power consumption change information of the backup storage battery 12, the power consumption status Regarding the backup storage battery 12 in each facility 10 equipped with different backup devices, the backup storage battery 12 with a large change in power consumption is charged with a higher priority, and the backup storage battery 12 with a small change in power consumption is with a lower priority. Charging using the in-vehicle storage battery 32 of the automobile 30 can be performed.

  Therefore, based on the remaining battery capacity of the backup storage battery 12, the device information, and the power consumption change information of the backup storage battery 12, the remaining battery capacity of the backup storage battery 12 is lost or cannot be put to practical use. It is possible to predict the amount of zero time and determine the priority order based on the predicted remaining time information of the remaining time. It is possible to realize charging that enables continuous use.

  In the above-described embodiment, the control unit 3 holds all the importance information, power consumption change information, and zero remaining time information of the backup storage battery 12 of each facility 10 held in the database 7 or among these. Since the priority for charging is determined from any one of these, or a combination thereof, the backup storage battery 12 having a high degree of importance is used in accordance with the purpose of use of the backup device provided in each facility 10. By setting the higher priority, the battery 30 can be charged using the in-vehicle storage battery 32 before the remaining battery level is reduced or until it cannot be practically used, and the backup is continued. The device can be used. On the other hand, the backup battery 12 with a low importance that allows the remaining battery capacity to be temporarily reduced to zero is given a lower priority, so that the backup storage battery 12 with a high importance in other facilities is used. It becomes possible to prioritize the charging of.

  In addition to the above, the conditions for determining the priority order may employ these distances based on the location information of the facility and the location information of the automobile 30 to be guided. In this case, as shown in FIG. 18, the database 7 has an evaluation point table regarding the distance between the facility and the car to be guided, and when the distance is longer than 90 km, it is 10 points, longer than 80 km and shorter than 90 km. 9 points, 8 points for longer than 70 km and 80 km or shorter, 7 points for longer than 60 km and 70 km or shorter, 2 points for longer than 10 km and 20 km or shorter, 1 point for 10 km or shorter. As described above, the longer the distance between the facility and the automobile to be guided, the faster it is necessary to respond, so the evaluation score is set higher. However, in this case, it is necessary to acquire the vehicle position information of each vehicle 30 before determining the priority order of the facilities.

  In the above embodiment, an automobile is used as a means for charging the backup storage battery 12 of each facility. However, the present invention is not limited to this. For example, a mobile power supply car standing by at a predetermined location is used. May be used. In this case as well, charging is performed sequentially based on the priority order in each facility 10. Further, when the mobile power supply vehicle is waiting at a plurality of locations, it is effective to determine the charging plan based on the mobile power supply vehicle position information, as with the automobile.

  Moreover, not only a mobile power supply vehicle but an emergency generator (diesel engine or gas turbine engine) may be mounted on a transport vehicle and charged sequentially based on the priority of each facility. Even in this case, when waiting at a plurality of places, it is effective to determine the charging plan based on the position information of the transporting vehicle.
