  By the way, the electric power stored in the shared storage battery 14 is distributed to each dwelling unit 12 so as to be shared and used by each dwelling unit 12, but in the present embodiment, when the electric power stored in the shared storage battery 14 is distributed. Has a plurality of modes predetermined for each supply state of the grid power 20, and switches the mode according to the supply state of the grid power 20 to distribute the power stored in the shared storage battery 14 to each dwelling unit 12. It has become. Specifically, in the present embodiment, the supply state of the system power 20 (for example, the normal state in which the system power 20 is supplied, the power failure state in which the supply of the system power 20 is temporarily stopped, the system power 20 A disaster state or the like in which supply is continuously stopped is detected, and the mode (distribution method) is switched based on the detected supply state of the grid power 20. In addition, when power is distributed, the amount of surplus power supplied to the shared storage battery 14 differs from one dwelling unit 12 to another, and therefore it becomes unfair if it is evenly distributed. To determine the distribution amount.

  As shown in FIG. 3, the plurality of modes for distributing the power stored in the shared storage battery 14 of the present embodiment has three modes: a normal mode, a power failure mode, and a disaster mode. The electric power stored in the shared storage battery 14 is distributed according to a predetermined distribution method.

  Specifically, in the normal case where no power outage or disaster has occurred, the normal mode is set, and the shared storage battery 14 is charged with the surplus power of each dwelling unit 12, resulting in a shortage of power in each dwelling unit 12. Is distributed according to the amount of electricity stored in the shared storage battery 14. That is, the electric power that contributes to the charging of the shared storage battery 14 is distributed to each dwelling unit 12.

  Further, when a power failure occurs, the power failure mode is set, and 50% of the amount of electricity stored in the shared storage battery 14 is an unpowered dwelling unit (a unit 12 in which the amount of electricity stored in the shared storage battery 14 is less than a predetermined value or is not charged at all. The remaining 50% is distributed to the power storage dwelling unit (the dwelling unit 12 that has stored power exceeding the predetermined value in the common storage battery 14) according to the amount of power stored in the common storage battery 14. At this time, the power selling cost to the unpowered dwelling unit is distributed to the power storage dwelling unit. As a specific example of the distribution method of the power selling expenses, for example, the distribution may be made by paying with the residents' association fee in the area, or other methods may be used.

At this time, the power selling cost is distributed to the power storage unit including the cost of purchasing power at the power storage unit. For the detection of the occurrence of a disaster, the shared storage battery control device 16 may monitor the grid power 20 and detect a power outage for a predetermined time or more as a disaster, or may be a power company or other public institution. Disaster information may be acquired via the network 28 to detect the occurrence of a disaster.

  Subsequently, an example of specific processing performed by executing each program stored in the shared storage battery control device 16 and the HEMS 26 in the storage battery sharing system 10 according to the embodiment of the present invention configured as described above. Will be described.

  First, an example of processing performed in the HEMS 26 provided in each dwelling unit 12 in the storage battery sharing system 10 according to the embodiment of the present invention will be described. FIG. 4 is a flowchart showing an example of processing performed in the HEMS 26 in the storage battery sharing system 10 according to the embodiment of the present invention. Note that the processing in FIG. 4 is performed at predetermined time intervals, for example.

  First, in step 100, the power consumption is detected, and the process proceeds to step 102. That is, the CPU 30 acquires the detection result of the amount of power supplied to the home appliances / equipment detected by the distribution board 48 of each dwelling unit 12 through the power control unit 18 to detect the power consumption.

  In step 102, it is determined whether there is a storage battery 52 or not. This determination is made by detecting whether or not the storage battery 52 is connected to the power control unit 18. Specifically, the power control unit 18 has a function of detecting the connection of the storage battery 52, and the power control unit 18 detects the connection of the storage battery 52 and the CPU 30 acquires the detection result. If the determination is affirmative, the process proceeds to step 104, and if the determination is negative, the process proceeds to step 106.

  In step 104, the amount of power stored in the storage battery 52 is detected, and the routine proceeds to step 106. Detection of the storage amount of the storage battery 52 is performed when the power control unit 18 detects the storage amount and the CPU 30 acquires the detection result.

  In step 106, it is determined whether there is a vehicle storage battery. As in step 102, the determination is also made by detecting whether or not a vehicle storage battery (vehicle 56) is connected to the power control unit 18. If the determination is affirmative, the process proceeds to step 108. If the result is negative, the process proceeds to step 110.

  In step 108, the amount of power stored in the vehicle storage battery is detected, and the routine proceeds to step 110. Similarly to step 104, the storage amount of the vehicle storage battery is detected when the CPU 30 acquires the detection result of the storage amount detected by the power control unit 18.

  In step 110, it is determined whether or not there are various power generation devices 54. This determination is performed by detecting whether or not various power generation devices 54 are connected to the power control unit 18. Specifically, the power control unit 18 has a function of detecting the connection of the various power generation devices 54, and the power control unit 18 detects the connection of the various power generation devices 54 and the CPU 30 acquires the result to determine. Is done. If the determination is affirmative, the process proceeds to step 112, and if the determination is negative, the process proceeds to step 114.

  In step 112, the power generation amount of the various power generation devices 54 is detected, and the routine proceeds to step 114. The detection of the power generation amount of the various power generation devices 54 is performed by the CPU 30 obtaining the detection result of the power generation amount detected by the power control unit 18.

  In step 114, surplus power is calculated, and the process proceeds to step 116. The surplus power is calculated based on the power consumption, the amount of electricity stored, and the amount of power generation detected in the above steps. That is, a value obtained by subtracting the amount of power consumption from the total value of the generated power and the amount of stored electricity is obtained. At this time, when the calculated value is positive, there is surplus power, but when it is negative, there is no surplus power and the power is insufficient.

  In step 116, it is determined whether or not there is surplus power. If the determination is negative, the process proceeds to step 118. If the determination is affirmative, the process proceeds to step 122.

  In step 118, it is determined whether or not power is insufficient. The determination is made, for example, by determining whether or not there is a shortage of the power amount or more in each dwelling unit 12 in consideration of the power amount of the storage battery 52, and when the determination is affirmed, the process proceeds to step 120. If the result is negative, the series of processing ends. Note that the determination in step 118 may be omitted, and the process may proceed to step 120.

  In step 120, a power supply request is transmitted to shared storage battery control device 16. As a result, the shared storage battery control device 16 distributes electric power according to the amount of electricity stored in the shared storage battery 14 of the dwelling unit 12.

  On the other hand, in step 122, control is performed to charge the surplus power to the shared storage battery 14, and the process proceeds to step 124. That is, surplus power generated by the various power generation devices 54 is charged to the shared storage battery 14 via the power control unit 18 of each dwelling unit 12 and the power control unit 18 connected to the shared storage battery.

  In step 124, the charging information is transmitted to the shared storage battery control device 16, and the series of processes is terminated.

  Next, an example of processing performed by the shared storage battery control device 16 will be described. FIG. 5 is a flowchart showing an example of processing performed by the shared storage battery control device 16 in the storage battery sharing system 10 according to the embodiment of the present invention. Note that the processing of FIG. 5 is also performed at predetermined time intervals, for example.

  In step 200, it is determined whether or not the charging information of each dwelling unit 12 has been received. If the determination is affirmative, the process proceeds to step 202. If the determination is negative, the process proceeds to step 204.

  In step 202, the charging information is stored and the process proceeds to step 204. That is, information indicating the amount of charge from each dwelling unit 12 to the shared storage battery 14 is stored in the memory 44 of the shared storage battery control device 16 or the like.

  In step 204, it is determined whether there is a power supply request. This determination determines whether or not a power supply request has been made from the HEMS 26 of each dwelling unit 12 by the above-described step 120. If the determination is affirmative, the process proceeds to step 206. If the determination is negative, the determination is a step. Returning to 200, the above-described processing is repeated.

  In step 206, it is determined whether a power failure has occurred. For example, as described above, the shared storage battery control device 16 monitors the grid power 20 to detect the occurrence of a power outage or obtains information from the power company via the network 28 or the like to determine the power outage. It is determined by detecting. If the determination is affirmative, the process proceeds to step 208, and if the determination is negative, the process proceeds to step 214.

  In step 208, the charge history is read and the routine proceeds to step 210. That is, information representing the amount of electricity stored from each dwelling unit 12 to the shared storage battery 14 stored in step 202 described above is read from the memory 44 or the like as a charging history. Thereby, the charge amount from each dwelling unit 12 to the shared storage battery 14 can be grasped.

  In step 210, the amount of stored electricity for each dwelling unit 12 is detected, and the routine proceeds to step 212. That is, the amount of electricity stored in the shared storage battery 14 by each dwelling unit 12 is detected from the charging history.

  In step 212, 50% of the amount of electricity stored in the shared storage battery 14 is supplied (sold) to an unpowered dwelling unit (a unit 12 where the amount of electricity stored in the shared storage battery 14 is equal to or less than a predetermined value or not stored at all). The power control unit 18 is controlled to distribute 50% of the amount to the electricity storage dwelling unit (the dwelling unit 12 that has stored electricity exceeding the predetermined value to the shared storage battery 14) according to the amount of electricity stored by each dwelling unit 12, and a series of processes Exit. Thereby, in the case of a power failure, half of the power stored in the shared storage battery 14 is sold, and the other half is distributed to the dwelling unit 12 that has stored power according to the amount of power stored. Therefore, the electric power stored in the shared storage battery 14 can be distributed without causing an unfair feeling.

  On the other hand, in step 214, it is determined whether a disaster has occurred. In the determination, for example, as described above, the shared storage battery control device 16 monitors the grid power 20 and detects a power outage of a predetermined time or more as a disaster, or a disaster from an electric power company or other public organizations. The determination is made by acquiring information via the network 28 and detecting the occurrence of a disaster. If the determination is affirmative, the process proceeds to step 216. If the determination is negative, the process proceeds to step 218.

  In step 216, the power control unit 18 is controlled so as to supply (sell) all the power of the shared storage battery 14 to each dwelling unit, and the series of processing ends. That is, in the case of a disaster, all the electric power stored in the shared storage battery 14 after shifting to the disaster mode is sold to each dwelling unit 12.

  On the other hand, in step 218, the charge history is read and the process proceeds to step 220. That is, information representing the amount of electricity stored from each dwelling unit 12 to the shared storage battery 14 stored in step 202 described above is read from the memory 44 or the like as a charging history. Thereby, the charge amount from each dwelling unit 12 to the shared storage battery 14 can be grasped.

  In step 220, if the power supply request is an unpowered dwelling unit, power is sold, and if it is a power storage dwelling unit, the power stored in the shared storage battery 14 is distributed according to the amount of power stored in the shared storage battery 14. The control unit 18 is controlled to end the series of processes.

  Thus, in this Embodiment, since the distribution amount to each dwelling unit 12 of the electric power stored in the shared storage battery 14 is determined and distributed based on the supply state of the system power 20, according to the supply state of the power Power can be distributed appropriately.

  Further, in the normal mode and the power failure mode, power is distributed according to the amount of power stored in the shared storage battery 14 of each dwelling unit 12, so that power can be appropriately distributed without unfairness.

  In the above embodiment, in the power outage mode, half of the amount of electricity stored in the shared storage battery 14 is supplied to the non-electric storage unit and sold, and the other half is distributed to the electric storage unit. The ratio of distribution with electricity is not limited to this. That is, a predetermined ratio of the amount of electricity stored in the shared storage battery 14 may be supplied to the unpowered dwelling unit for sale, and the remaining ratio may be distributed to the power storage dwelling unit. Further, the predetermined ratio may be set by the operation unit 42 of the shared storage battery control device 16.
