[0013] A management system according to one embodiment of the present invention will be described in detail below with reference to the drawings. In the following description of the drawings, identical or similar parts are denoted by identical or similar reference numerals. The management system according to this embodiment includes a plurality of power generation units, each including one or more solar power generation panels, arranged in a facility, a plurality of storage batteries that store electricity generated by each of the plurality of power generation units, and a management device. Below, an apartment building will be described as an example of the facility, but the facility is not limited to an apartment building.

[0014] Fig. 1 is a diagram showing an example of a conventional disaster prevention system for an apartment building. For example, in the disaster prevention system shown in Fig. 1, a plurality of power generation units U, each including a plurality of photovoltaic power generation panels, are placed on the roof of an apartment building A, and electricity generated by the plurality of power generation units U is stored in a single large stationary storage battery B via wiring L1. In addition, in the disaster prevention system, in the event of a power outage due to a disaster or the like, the electricity stored in the stationary storage battery B is supplied as emergency power to each residence and common areas such as elevators via wiring L2.

[0015] However, in the disaster prevention system shown in Figure 1, emergency power is stored in one large fixed storage battery B, so if at least one of the wiring L1 and L2 connected to the fixed storage battery B is cut off due to a disaster or the like, there is a risk that the power stored in the fixed storage battery B will not be fully utilized as emergency power.

[0016] On the other hand, as shown in FIG. 2, the management system 1 according to this embodiment includes a plurality of power generation units 10, each including one or more photovoltaic power generation panels 101 arranged in an apartment building A, a plurality of storage batteries 20 that store electricity generated by the plurality of power generation units 10, and a management device 50. In the management system 1 according to this embodiment, instead of the large, stationary storage battery B as shown in FIG. 1, a plurality of storage batteries 20 that store electricity generated by the plurality of power generation units 10 are provided. Therefore, even if some of the storage batteries 20 become unavailable as emergency power due to a wiring break in the event of an emergency such as a disaster, the remaining storage batteries 20 can be used as emergency power. In this way, the management system 1 according to this embodiment can reduce the impact of wiring breaks in an emergency and more stably supply emergency power to the apartment building A.

[0017] In addition, in the management system 1 of this embodiment, by making at least one of the multiple storage batteries 20 portable, the portable storage battery 20 can be relocated within the apartment building A in an emergency, thereby enabling a more stable supply of emergency power in the apartment building A.

[0018] (composition) The configuration of the management system 1 according to this embodiment will be described below. <Outline configuration> Fig. 2 is a diagram showing a schematic configuration of a management system according to this embodiment. As shown in Fig. 2, the management system 1 includes a plurality of power generating units 10, a plurality of storage batteries 20, a plurality of wirings 30 connected to the plurality of power generating units 10 and the plurality of storage batteries 20, a management device 50 connected to the plurality of power generating units 10 and the plurality of storage batteries 20 via a network 40, and a terminal 60. For example, in Fig. 2, N (N>1) power generating units 101 to 10 N-1 are installed in a specific location (for example, on the roof) of the apartment building A, and N wirings 301 to 30 N-1 N storage batteries 201 to 20 N-1 is connected to.

[0019] Each of the multiple power generation units 10 includes one or more solar power generation panels 101. For example, as shown in FIG. 2, each of the multiple power generation units 10 may include multiple solar power generation panels 101. The number of solar power generation panels 101 included in each power generation unit 10 may be determined based on at least one of the amount of power generated per solar power generation panel 101 and the capacity of the storage battery 20. Each of the multiple power generation units 10 is connected to the storage battery 20 via wiring 30. In FIG. 2, each power generation unit 10 and each storage battery 20 correspond one-to-one, but this is not limited thereto, and multiple storage batteries 20 may correspond to one power generation unit 10, or one storage battery 20 may correspond to multiple power generation units 10.

[0020] The multiple storage batteries 20 are distributed throughout the apartment complex A. For example, each of the multiple storage batteries 20 is disposed in each room of the apartment complex A, in common areas, etc. At least one of the multiple storage batteries 20 is a portable storage battery 20, but this does not exclude the inclusion of a fixed storage battery 20. Each storage battery 20 stores electricity generated by a power generation unit 10 connected via wiring 30. Furthermore, each storage battery 20 supplies power to a device (not shown) (for example, a smartphone, lighting, etc.).

[0021] Furthermore, as will be described later, the portable storage battery 20 may be rearranged, i.e., the room in which it is placed may be changed. The portable storage battery 20 may be rearranged by changing the connections of the wiring 30 while connected to the same power generation unit 10 as before the rearrangement, or may be rearranged by changing the connections of the wiring 30 while connected to a power generation unit 10 different from before the rearrangement.

[0022] Each wiring 30 transmits electricity generated by each power generation unit 10 to each storage battery 20. Note that Fig. 2 is a schematic diagram, and the positions of each power generation unit 10, each storage battery 20, and wiring 30 are not limited to those shown in the figure. For example, in Fig. 2, apartment building A does not have multiple floors, but it may have multiple floors.

[0023] The network 40 is a wireless and / or wired network that connects each power generation unit 10 or each storage battery 20 to a management device 50. The management device 50 is a device that manages each power generation unit 10 and each storage battery 20 arranged in the apartment building A. The terminal 60 may be a PC, a smartphone, or the like used by an administrator of the management system 1 or a user of the apartment building A (facility).

[0024] <Hardware configuration> 3 is a diagram showing an example of the hardware configuration of each device according to this embodiment. Each device (for example, one or more devices mounted on the power generation unit 10, one or more devices mounted on the storage battery 20, the management device 50, or the terminal 60) has a processor 11 such as a CPU (Central Processing Unit) corresponding to an arithmetic device, a memory unit 12, a transmitter / receiver unit 13, and an input / output unit 14. These components are connected via a bus so as to be able to transmit and receive data to and from each other. The specified device mounted on the power generation unit 10 or the storage battery 20 is, for example, a chip, an electronic device, an integrated circuit, etc.

[0025] The processor 11 is, for example, a CPU (Central Processing Unit) and controls each device in the management system 1. The processor 11 may execute various processes described in this embodiment by reading and executing a program from the storage unit 12. Each device in the management system 1 may be configured with one or more processors 11. Furthermore, each device may be called a computer.

[0026] The storage unit 12 is configured with, for example, storage such as a memory, a hard disk drive (HDD), and / or a solid state drive (SSD), etc. The storage unit 12 may store various information necessary for the processor 11 to execute processing (for example, a program executed by the processor 11, etc.).

[0027] The transceiver 13 is a device that communicates via the network 40 and may include, for example, a network card, a communication module, a chip, an antenna, etc. The transceiver 13 may include a transmitter that transmits various types of information via the network 40 and / or a receiver that receives various types of information via the network 40.

[0028] The input / output unit 14 includes an input unit such as a keyboard, a touch panel, a mouse, and / or a microphone, and an output unit such as a display and / or a speaker. The input unit accepts input of various information from a user. The output unit may also include a display unit that displays various information to the user.

[0029] The hardware configuration described above is merely an example. Each information processing device may omit some of the hardware shown in FIG. 3, or may include hardware not shown in FIG. 3. The hardware shown in FIG. 3 may be configured with one or more chips. When an information processing device is configured with multiple devices, each device may include at least some of the hardware.

[0030] <Functional configuration> Fig. 4 is a diagram showing an example of the functional configuration of the management system 1 according to this embodiment. As shown in Fig. 4, the management device 50 includes a management unit 501, an acquisition unit 502, a derivation unit 503, a determination unit 504, an output unit 505, and a detection unit 506. Note that the management unit 501, the acquisition unit 502, the derivation unit 503, the determination unit 504, and the output unit 505 may be realized by at least a part of the storage unit 12, the transmission / reception unit 13, the input / output unit 14, and the program executed by the processor 11 of the management device 50.

[0031] The management unit 501 manages information (hereinafter referred to as "location information") regarding the location of each of the multiple storage batteries 20 installed in the apartment building A. The location information may include information (hereinafter referred to as "consumption information") regarding the amount of electricity consumed for a predetermined period at each of the locations of the multiple storage batteries 20. The location information may also include information regarding the number of people living in each of the locations of the multiple storage batteries 20 (hereinafter referred to as "number of people information"). The location information may also include information indicating the floor on which each of the locations of the multiple storage batteries 20 is installed (hereinafter referred to as "floor information") and information indicating the room in each of the locations (hereinafter referred to as "room information"). The location information may also include an identifier (hereinafter referred to as "battery ID") of the storage battery 20 installed at that location.

[0032] Fig. 5 is a diagram showing an example of location information of each storage battery 20 according to this embodiment. As shown in Fig. 5, the location information may include, for example, a storage battery ID, room information indicating the room in which each storage battery 20 is located, floor information indicating the floor in which each storage battery 20 is located, occupancy number information indicating the number of occupants in the room in which each storage battery 20 is located, and consumption amount information indicating the amount of electricity consumed per unit time in the room in which each storage battery 20 is located.

[0033] The "room" in which each storage battery 20 is placed may be any section of the apartment building A, and is not limited to an exclusive section such as a living space, but may include any section related to the apartment building A, such as a management office, lobby, elevator, staircase, storeroom, or other common areas. The consumption information may be, for example, the amount of electricity consumed per unit time supplied by the electric power company under normal circumstances, or the amount of electricity supplied per unit time to a device connected to each storage battery 20 in an emergency when the supply of electricity from the electric power company is stopped.

[0034] The acquisition unit 502 acquires information regarding the state of each of the multiple storage batteries 20 (hereinafter referred to as "power storage state information"). Here, the state of each storage battery 20 may be, but is not limited to, the amount of power stored in each storage battery 20, the ratio of the amount of power stored to the capacity of each storage battery 20 (hereinafter referred to as "remaining power amount"), an operating state (for example, operating, stopped), an abnormality, and / or normality. Note that the acquisition unit 502 may acquire the power storage state information from each storage battery 20, or may acquire it from another device that collects information on each storage battery 20.

[0035] The acquisition unit 502 may also acquire information related to weather (hereinafter referred to as "weather information"). The weather information is used to predict the amount of power generation in each of the multiple power generation units 10, and may include information related to the amount of sunlight. For example, the acquisition unit 502 may acquire weather information from a device (not shown) via the network 40.

[0036] The derivation unit 503 derives information on the amount of stored power of each storage battery 20 (hereinafter referred to as "storage power amount information") based on the power storage state information acquired by the acquisition unit 502. Here, the storage power amount information indicates the remaining amount of stored power, which is the ratio of the amount of stored power to the capacity of each storage battery 20, but is not limited to this and may indicate the amount of stored power itself of each storage battery 20. For example, the derivation unit 503 may derive storage power amount information indicating the remaining amount of stored power, which is the ratio of the amount of stored power to the capacity of each storage battery 20, based on the amount of stored power indicated by the power storage state information acquired by the acquisition unit 502. Alternatively, the derivation unit 503 may derive the remaining amount of stored power indicated by the power storage state information acquired by the acquisition unit 502 as the storage power amount information.

[0037] Furthermore, the derivation unit 503 may derive the remaining time of each storage battery 20 based on the stored power amount information derived as described above and the consumption amount information managed by the management unit 501. For example, the derivation unit 503 may derive the remaining time of each storage battery 20 to be used in an emergency based on the remaining amount of stored power indicated by the stored power amount information and the consumption amount per unit time indicated by the consumption amount information.

[0038] Furthermore, the derivation unit 503 may derive the amount of power generated in the power generating unit 10 that supplies power to each storage battery 20 via the wiring 30, based on the weather information acquired by the acquisition unit 502. Specifically, the derivation unit 503 may predict the amount of power generated in the power generating unit 10 corresponding to the weather information acquired by the acquisition unit 502, based on a model that is machine-learned using learning data that associates past weather information with past amounts of power generated in the power generating unit 10 under conditions indicated by the past weather information.

[0039] The determination unit 504 determines, based on the placement location information and the stored power amount information, a storage battery 20 that is a candidate for changing the placement location (hereinafter referred to as a "relocation candidate") from among the multiple storage batteries 20. Specifically, the determination unit 504 may determine, as the relocation candidate, a storage battery 20 whose stored power amount information satisfies a first condition (for example, the remaining amount of stored power or the stored power amount indicated by the stored power amount information is less than or equal to a predetermined threshold) and a storage battery 20 whose stored power amount information satisfies a second condition (for example, the remaining amount of stored power or the stored power amount indicated by the stored power amount information is equal to or greater than a predetermined threshold).

[0040] Furthermore, the determination unit 504 may determine a room (hereinafter referred to as a "relocation position") to which the storage battery 20 determined as a relocation candidate is to be relocated, based on the relocation location information and the stored power amount information. For example, the determination unit 504 may determine a room in which a storage battery 20 satisfying the first condition is located as the relocation position for the storage battery 20 satisfying the second condition. Furthermore, the determination unit 504 may determine a room in which a storage battery 20 satisfying the second condition is located as the relocation position for the storage battery 20 satisfying the first condition.

[0041] Specifically, the determination unit 504 may determine a storage battery 20 to be a relocation candidate based on the consumption amount information managed by the management unit 501 and the stored power amount information derived by the derivation unit 503. For example, the determination unit 504 may determine, as the relocation candidate, a storage battery 20 whose remaining time derived by the derivation unit 503 based on the consumption amount information and the stored power amount information satisfies a first condition (e.g., equal to or less than a predetermined threshold) and a storage battery 20 whose remaining time satisfies a second condition (e.g., equal to or greater than a predetermined threshold).

[0042] Furthermore, the determination unit 504 may determine the relocation location of the storage battery 20 determined as a relocation candidate based on the consumption amount information and the stored power amount information. For example, the determination unit 504 may determine a room in which the consumption amount indicated by the consumption amount information (e.g., the amount of electricity consumed per unit time in the room in which each storage battery 20 is placed) satisfies a third condition (e.g., equal to or greater than a predetermined threshold) as the relocation location of the storage battery 20 in which the remaining amount of stored power or the stored power amount indicated by the stored power amount information or the remaining time satisfies the second condition. On the other hand, the determination unit may determine a room in which the consumption amount satisfies a fourth condition (e.g., equal to or less than a predetermined threshold) as the relocation location of the storage battery 20 in which the remaining amount of stored power or the stored power amount indicated by the stored power amount information or the remaining time satisfies the first condition.

[0043] Furthermore, the determination unit 504 may determine a storage battery 20 to be a relocation candidate based on the number-of-residents information managed by the management unit 501 and the stored power amount information derived by the derivation unit 503. For example, based on the number-of-residents information and the stored power amount information, the determination unit 504 may determine, as relocation candidates, a storage battery 20 in which the remaining amount of stored power or the stored power amount per person in the room in which the storage battery 20 is located satisfies a first condition (e.g., less than or equal to a predetermined threshold) and a storage battery 20 in which the remaining amount of stored power or the stored power amount per person satisfies a second condition (e.g., not less than or equal to a predetermined threshold).

[0044] Furthermore, the determination unit 504 may determine the relocation location of the storage battery 20 determined as a relocation candidate based on the number-of-occupants information and the stored power amount information. For example, the determination unit 504 may determine a room in which the number of occupants indicated by the number-of-occupants information satisfies a third condition (e.g., equal to or greater than a predetermined threshold) as the relocation location of the storage battery 20 in which the remaining amount of stored power or the stored power amount indicated by the stored power amount information or the remaining time satisfies the second condition. On the other hand, the determination unit may determine a room in which the number of occupants satisfies a fourth condition (e.g., equal to or less than a predetermined threshold) as the relocation location of the storage battery 20 in which the remaining amount of stored power or the stored power amount indicated by the stored power amount information or the remaining time satisfies the first condition.

[0045] The output unit 505 outputs list information indicating the storage amount information along with the location of each of the plurality of storage batteries 20. The output unit 505 may also output individual information of each storage battery 20.

[0046] Fig. 6 is a diagram showing an example of list information according to this embodiment. As shown in Fig. 6, the list information may show information about the amount of stored power of each storage battery 20, along with information about the floor and room where each storage battery 20 is located. For example, in Fig. 6, the information about the amount of stored power of each storage battery 20 is shown as a bar graph meter indicating the remaining amount of stored power, but this is not limited to this. Of course, the information about the amount of stored power of each storage battery 20 in the list information may be in other forms not shown, such as numerical values.

[0047] 7 is a diagram showing an example of individual information of each storage battery 20 according to this embodiment. As shown in FIG. 7, the individual information of the storage battery 20 may include at least one of the storage battery ID (e.g., #0) of the storage battery 20, stored power amount information (e.g., remaining stored power amount), information indicating the remaining time (hereinafter referred to as "remaining time information"), and information indicating the amount of power generation predicted by the derivation unit 503 (hereinafter referred to as "power generation amount prediction information"). Note that the stored power amount information, remaining time information, and power generation amount prediction information may be derived by the derivation unit 503.

[0048] For example, when a specific room (e.g., 501) in apartment building A is selected by a user on the screen of terminal 60 displaying the list information shown in FIG. 6, acquisition unit 502 may acquire the user's selection result accepted by terminal 60, and output unit 505 may output individual information of storage battery 20 located in the specific room based on the selection result.

[0049] Fig. 8 is a diagram showing another example of individual information related to each storage battery 20 according to this embodiment. As shown in Fig. 8, the individual information of the storage battery 20 may include at least one of the storage battery ID (e.g., #0) of the storage battery 20, current stored power amount information and consumption amount information, information related to the number of uses for each device estimated based on the stored power amount information (hereinafter referred to as "usage number information"), and stored power amount information after the usage amount has been used and consumption amount information when the usage number has been used.

[0050] Furthermore, the output unit 505 outputs information (hereinafter referred to as "relocation information") (not shown) relating to the storage battery 20 that is a relocation candidate determined by the determination unit 504. The relocation information may include, for example, at least one of information indicating the storage battery 20 that is a relocation candidate and information indicating the position of relocation.

[0051] The detection unit 506 detects a predetermined trigger. The predetermined trigger may be, for example, detection of an output request for rearrangement information from the terminal 60, or may be at a predetermined cycle.

[0052] (operation) Next, the operation of the management system 1 according to this embodiment will be described. Note that the operation in Figures 9 and 10 is merely an example, and it goes without saying that some steps may be omitted or some steps may be added.

[0053] <List information output operation> 9 is a diagram showing an example of the output operation of list information according to the present embodiment. In FIG. 9, it is assumed that the management device 50 manages the location information of each storage battery 20 in the apartment building A.

[0054] 9, in step S101, the management device 50 acquires power storage state information of each of the multiple storage batteries 20. In step S102, the management device 50 derives power storage amount information of each of the multiple storage batteries 20 based on the power storage state information acquired in step S101.

[0055] In step S103, the management device 50 outputs list information (for example, FIG. 6) showing stored power information along with the locations of the respective storage batteries 20. For example, the list information shown in FIG. 6 shows stored power information of the storage batteries 20 for each room on each floor of an apartment building, so that the user can easily determine in an emergency such as a disaster which room the remaining stored power of the storage batteries 20 is insufficient or surplus.

[0056] <Relocation information output operation> 10 is a diagram showing an example of an output operation of rearrangement information according to this embodiment. As shown in FIG. 10, in step S201, the management device 50 detects a predetermined trigger. The predetermined trigger may be, for example, detection of an output request of rearrangement information from the terminal 60, or may be at a predetermined periodic timing.

[0057] In step S202, the management device 50 determines, based on the installation location information and the stored power amount information, storage batteries 20 that will be candidates for relocation, among the multiple storage batteries 20. For example, the determination unit 504 may determine, as relocation candidates, a set of storage batteries 20 whose stored power amount information satisfies a first condition (e.g., the remaining amount of stored power or the stored power amount indicated by the stored power amount information is less than or equal to a predetermined threshold) and storage batteries 20 whose stored power amount information satisfies a second condition (e.g., the remaining amount of stored power or the stored power amount indicated by the stored power amount information is equal to or greater than a predetermined threshold).

[0058] In step S203, the management device 50 outputs relocation information indicating the relocation candidates determined in step S202.

[0059] As described above, in the management system 1 according to this embodiment, instead of a large fixed storage battery B as shown in Fig. 1, multiple storage batteries 20 that store electricity generated by multiple power generation units 10 are provided, thereby reducing the impact of wiring breaks in an emergency and enabling a more stable supply of emergency power in the apartment building A. Furthermore, in the management system 1 according to this embodiment, by making at least one of the multiple storage batteries 20 portable, the portable storage battery 20 can be relocated within the apartment building in an emergency, enabling a more stable supply of emergency power in the apartment building A.
