[0018] In addition, in the present embodiment, the power storage device 30 and the power supply device 40 constitute a power storage system 3 (see FIG. 1).

[0019] (2) Configuration (2.1) Power storage system Here, the configurations of the power storage device 30 and the power supply device 40 included in the power storage system 3 will be described.

[0020] (2.1.1) Power storage device As shown in FIG. 2, the power storage device 30 includes a storage battery 31, a communication unit 32, a control unit 33, and a first output unit 34. The power storage device 30 is mounted on the power supply device 40. That is, the storage battery 31 is mounted on the power supply device 40.

[0021] The power storage device 30 has, for example, a computer system having a processor and a memory. Then, when the processor executes a program stored in the memory, the computer system functions as the control unit 33. The program executed by the processor is recorded in advance in the memory of the computer system here, but it may be recorded and provided on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0022] The storage battery 31 has a plurality of lithium-ion batteries connected thereto and is configured to be capable of repeating charge and discharge.

[0023] The communication unit 32 is a communication interface (communication circuit) for communicating with the position detection sensors 20 (scanners 21, 22). The communication unit 32 communicates with the position detection sensors 20 by wireless communication.

[0024] The control unit 33 has a first transmission processing unit 33a and a second transmission processing unit 33b.

[0025] The first transmission processing unit 33a transmits, as position information regarding the position of the storage battery 31, identification information including a battery identifier for identifying the storage battery 31 included in the power storage device 30, which is pre-stored, to the position detection sensor 20 via the communication unit 32. The control unit 33 transmits the identification information using the power of the storage battery 31. In other words, the specific information as the identification information is information transmitted using the power of the storage battery 31.

[0026] The second transmission processing unit 33b transmits, as remaining amount information including the remaining amount of the storage battery 31, information regarding the usage state to the position detection sensor 20 via the communication unit 32. The second transmission processing unit 33b transmits the remaining amount information using the power of the storage battery 31. In other words, the remaining amount information is information transmitted using the power of the storage battery 31.

[0027] That is, the control unit 33 transmits the remaining amount information and the identification information using the communication unit 32, which is the same communication interface (communication circuit).

[0028] In the present embodiment, the power storage device 30 individually and periodically transmits the remaining amount information and the identification information to the position detection sensor 20. Note that the power storage device 30 may collectively and periodically transmit the remaining amount information and the identification information to the position detection sensor 20.

[0029] The control unit 33 receives notification information including arrangement relation information regarding the storage battery 31 and remaining amount relation information regarding the storage battery 31 from the server 10 via the communication unit 32 and the position detection sensor 20. Here, the arrangement relation information is information including the battery identifier of the storage battery 31 (target storage battery) whose remaining amount is equal to or less than a predetermined value and the identifier of the position detection sensor 20 (hereinafter referred to as "sensor identifier") that communicates with the power storage device 30 including the target storage battery. The power storage related information is information including a message indicating that charging of the target storage battery is necessary.

[0030] When the battery identifier of the target storage battery included in the arrangement relationship information of the notification information matches the battery identifier stored in advance, the control unit 33 outputs the message included in the power storage related information to the power supply device 40, causing the power supply device 40 to notify the user using the target storage battery of the message. When the battery identifier of the target storage battery included in the arrangement relationship information of the notification information does not match the battery identifier stored in advance, the control unit 33 discards the received notification information.

[0031] The first output unit 34 includes a USB (Universal Serial Bus) port. The first output unit 34 supplies (outputs) the power of the storage battery 31 to the device connected via the USB port.

[0032] (2.1.2) Power Supply Device As shown in FIG. 2, the power supply device 40 has a conversion unit 41, a second output unit 42, and a notification unit 43.

[0033] The conversion unit 41 converts the DC power output from the storage battery 31 of the power storage device 30 mounted on the power supply device 40 into AC power.

[0034] The second output unit 42 includes an AC power port. The second output unit 42 outputs the AC power converted by the conversion unit 41 to the device connected to the AC power port.

[0035] The notification unit 43 includes a speaker. When the notification unit 43 receives a message included in the power storage related information from the power storage device 30, it outputs the received message as voice from the speaker.

[0036] Note that the notification unit 43 may further include a display unit. In this case, the notification unit 43 outputs the received message as voice and also displays it on the display unit. Or, the notification unit 43 may only display the received message on the display unit.

[0037] (2.2) Battery Management System Here, the configurations of the position detection sensor 20 and the server 10 (management system 2) included in the battery management system 1 will be described respectively.

[0038] (2.2.1) Position Detection Sensor One or more (two in FIG. 1) position detection sensors 20 provided in the space 5 are, for example, scanners 21, 22.

[0039] Each position detection sensor 20 is configured to be communicable with a plurality of power storage devices 30 each including a plurality of storage batteries 31. Each position detection sensor 20 is configured to be communicable with the power storage devices 30 existing in the space 5 by wireless communication. More specifically, the position detection sensor 20 acquires information transmitted from each of the plurality of power storage devices 30 using a communication circuit (communication unit 32) provided in each of the plurality of power storage devices 30. Also, each position detection sensor 20 receives remaining amount information transmitted from each of the plurality of power storage devices 30 using the communication circuit of each power storage device 30.

[0040] Furthermore, the position detection sensor 20 is configured to be communicable with the server 10 via the network NT1.

[0041] The position detection sensor 20 communicates with the power storage devices 30 existing within the detection range of the position detection sensor 20 in the space 5. Specifically, the position detection sensor 20 receives a signal including identification information from the power storage device 30. When the position detection sensor 20 receives the identification information, the position detection sensor 20 transmits detection result information including the battery identifier included in the received identification information, the sensor identifier of the position detection sensor 20, and the reception intensity of the received signal, to the server 10 via the network NT1.

[0042] When the position detection sensor 20 receives remaining amount information from the power storage device 30, the position detection sensor 20 transmits the received remaining amount information including the sensor identifier of the position detection sensor 20, to the server 10 via the network NT1.

[0043] The position detection sensor 20 receives notification information including arrangement relation information and remaining amount relation information via the network NT1. When the sensor identifier included in the arrangement relation information of the notification information matches the sensor identifier stored in advance, that is, the sensor identifier of the position detection sensor 20, the position detection sensor 20 transmits the notification information to a plurality of power storage devices 30 existing within the detection range. For example, the position detection sensor 20 transmits the notification information by broadcast. When the sensor identifier included in the arrangement relation information of the notification information does not match the sensor identifier stored in advance, the position detection sensor 20 discards the received notification information.

[0044] (2.2.2) Server As shown in FIG. 1, the server 10 as the management system 2 includes a communication unit 11 and a control unit 13.

[0045] The server 10 has, for example, a computer system having a processor and a memory. When the processor executes a program stored in the memory, the computer system functions as the control unit 13. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be provided by being recorded on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0046] The communication unit 11 is a communication interface for communicating with each of one or more position detection sensors 20 provided in the space 5. The communication unit 11 communicates with each of one or more position detection sensors 20 provided in the space 5 via the network NT1.

[0047] The storage unit 12 is composed of a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), or the like. The storage unit 12 stores information acquired from each of one or more position detection sensors 20.

[0048] As shown in FIG. 1, the control unit 13 includes an acquisition unit 131, a determination unit 132, and a notification unit 133.

[0049] The acquisition unit 131 acquires position information regarding the positions of each of a plurality of portable storage batteries arranged in the space 5 and remaining amount information regarding the remaining amount from each of the plurality of storage batteries. The acquisition unit 131 includes a detection result acquisition unit 131a and a usage information acquisition unit 131b.

[0050] The detection result acquisition unit 131a acquires detection result information from each of one or more position detection sensors 20 arranged in the space 5. Specifically, the detection result acquisition unit 131a acquires the detection result information as position information from each of the one or more position detection sensors 20 via the network NT1. The detection result acquisition unit 131a stores the acquired detection result information (position information) in the storage unit 12.

[0051] The usage information acquisition unit 131b acquires remaining amount information regarding the remaining amount as usage information from each of the plurality of storage batteries 31 being used in the space 5. Specifically, the usage information acquisition unit 131b acquires, via the network NT1, the remaining amount information obtained from the power storage devices 30 existing within the detection range of the respective position detection sensors 20 from each of the one or more position detection sensors 20. In other words, the acquisition unit 131 acquires the remaining amount information transmitted from each of the plurality of power storage devices 30 each including a plurality of storage batteries 31 using the respective communication circuits of the power storage devices 30.

[0052] That is, the acquisition unit 131 acquires, via the network NT1, remaining amount information regarding the remaining amount from each of the plurality of storage batteries 31 being used in the space 5 and detection result information from each of the one or more position detection sensors 20 arranged in the space 5.

[0053] The determination unit 132 determines whether there is a battery 31 (target battery) that needs to be charged among the plurality of batteries 31 used in the space 5. Specifically, the determination unit 132 determines whether there is a battery 31 among the plurality of batteries 31 whose remaining amount is equal to or less than a predetermined value. More specifically, for each of the plurality of batteries 31, the determination unit 132 determines whether the remaining amount of the battery 31 is equal to or less than a predetermined value prestored for the battery 31.

[0054] When there is a target battery among the plurality of batteries 31, the notification unit 133 notifies arrangement relation information related to the position of the target battery based on the detection result of the position detection sensor 20 and remaining amount relation information related to the remaining amount of the target battery. That is, when the determination unit 132 determines that there is a target battery among the plurality of batteries 31, the notification unit 133 notifies the arrangement relation information and the remaining amount relation information for the target battery. Specifically, when there is a battery 31 among the plurality of batteries 31 whose remaining amount is equal to or less than a predetermined value, that is, when there is a target battery among the plurality of batteries 31, the notification unit 133 acquires, from the storage unit 12, the latest detection result information, which is information including the battery identifier of the target battery and the sensor identifier of the position detection sensor 20 that detected the target battery. The notification unit 133 notifies, via the network NT1, notification information including the arrangement relation information including the battery identifier and the sensor identifier of the acquired detection result information and the power storage related information including a message indicating that charging is required for the target battery. For example, the notification unit 133 broadcasts the notification information to one or more position detection sensors 20 via the network NT1.

[0055] In the embodiment, the notification unit 133 transmits the notification information to the power storage device 30 having the target battery, so that the power supply device 40 to which the target battery is attached among the plurality of power supply devices 40 outputs a voice based on the remaining amount relation information.

[0056] (3) Operations Here, the operation of the battery management system 1 will be described with reference to FIG. 3. Although FIG. 3 shows one power storage device 30, the battery management system 1 originally communicates with a plurality of power storage devices 30.

[0057] Each of the plurality of power storage devices 30 transmits identification information and remaining capacity information to the position detection sensor 20 (step S1). Specifically, the first transmission processing unit 33a transmits the identification information to the position detection sensor 20. The second transmission processing unit 33b transmits the remaining capacity information to the position detection sensor 20.

[0058] The position detection sensor 20 of the battery management system 1 receives the identification information and the remaining capacity information (step S2).

[0059] The position detection sensor 20 transmits a detection result including a battery identifier and a sensor identifier included in the identification information received from the power storage device 30, and the remaining capacity information to the server 10 (step S3).

[0060] The acquisition unit 131 of the server 10 performs an acquisition process (step S4). Specifically, the detection result acquisition unit 131a of the acquisition unit 131 acquires the detection result information from the position detection sensor 20. The detection result acquisition unit 131a stores the acquired detection result information in the storage unit 12. The usage information acquisition unit 131b of the acquisition unit 131 acquires the remaining capacity information from the position detection sensor 20.

[0061] The determination unit 132 of the server 10 performs a determination process (step S5). The determination unit 132 determines whether there is a battery 31 (target battery) among the plurality of batteries 31 used in the space 5 whose remaining capacity is equal to or less than a predetermined value. That is, the determination unit 132 determines for each of the plurality of batteries 31 whether the remaining capacity of the battery 31 is equal to or less than a predetermined value stored in advance for the battery 31.

[0062] The notification unit 133 performs a notification process (step S6). When there is a battery 31 among the plurality of batteries 31 whose remaining amount is equal to or less than a predetermined value (target battery), the notification unit 133 acquires, from the storage unit 12, the latest detection result information including the battery identifier of the target battery and the sensor identifier of the position detection sensor 20 that detected the target battery.

[0063] When there is a target battery among the plurality of batteries 31, the notification unit 133 transmits notification information including the arrangement relationship information including the battery identifier and the sensor identifier of the acquired detection result information, and the battery-related information including a message indicating that charging of the target battery is necessary, to the position detection sensor 20 (step S7).

[0064] The position detection sensor 20 receives notification information including the arrangement relationship information and the remaining amount relationship information from the server 10. When the sensor identifier included in the arrangement relationship information of the notification information matches the sensor identifier stored in advance, that is, the sensor identifier of the position detection sensor 20, the position detection sensor 20 transmits the notification information to one or more power storage devices 30 existing within the detection range (step S8). Note that when the sensor identifier included in the arrangement relationship information of the notification information does not match the sensor identifier stored in advance, the position detection sensor 20 discards the received notification information.

[0065] When the power storage device 30 receives the notification information from the server 10 via the position detection sensor 20, it performs a notification process (step S9). Specifically, when the battery identifier included in the arrangement relationship information of the notification information matches the battery identifier stored in advance, the power storage device 30 causes the power supply device 40 to notify the user using the target battery of the message included in the battery-related information. When the battery identifier included in the arrangement relationship information of the notification information does not match the battery identifier stored in advance, the power storage device 30 discards the received notification information.

[0066] (4) Advantages The battery management system 1 includes an acquisition unit 131 and a notification unit 133. The acquisition unit 131 acquires position information regarding the position of each of a plurality of portable batteries 31 arranged in the space 5 and usage information related to the usage state from each of the plurality of batteries 31. The notification unit 133 notifies arrangement relationship information and remaining amount relationship information when there is a target battery among the plurality of batteries 31 whose remaining amount is equal to or less than a predetermined value. The arrangement relationship information is information regarding the arrangement position of the target battery based on the position information. The remaining amount relationship information is information regarding the remaining amount of the target battery based on the usage information of the target battery.

[0067] Portable batteries are not used in a fixed location but in various locations. Therefore, in order to manage the charging of the batteries, it is necessary to know the location where the battery that needs to be charged is being used.

[0068] Therefore, according to the configuration of the battery management system 1, since the arrangement relationship information and the remaining amount relationship information are notified, the management of portable batteries can be easily performed.

[0069] (5) Variation Hereinafter, the variation will be described. Note that the variations described below can be applied in appropriate combination with the above-described embodiments.

[0070] (5.1) Variation 1 In the embodiment, the server 10 is configured to transmit the notification information to the power storage device 30 having the target battery, but the configuration is not limited to this.

[0071] The server 10 may transmit the notification information to a device other than the power storage device 30 having the target battery. For example, the server 10 may transmit the notification information to the information terminal 50 used by the user who uses the power storage device 30 having the target battery. Here, the information terminal 50 is, for example, a smartphone, a tablet terminal, or a personal computer.

[0072] The system configuration of the battery management system 1A according to Modification Example 1 is shown in FIG. 4. Hereinafter, the description will focus on the points different from the embodiment. Note that the same components as those in the embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0073] As shown in FIG. 4, the battery management system 1A of Modification Example 1 includes a server 10A as a management system 2 and scanners 21 and 22 as one or more (two in the illustrated example) position detection sensors 20.

[0074] The server 10 is configured to be communicable with one or more position detection sensors 20 and the information terminal 50 via the network NT1. Note that the server 10 may communicate with the information terminal 50 via a network other than the network NT1. That is, the communication between the server 10 and the position detection sensor 20 and the communication between the server 10 and the information terminal 50 may use different networks. For example, the communication between the server 10 and the position detection sensor 20 may use a dedicated line, and the communication between the server 10 and the information terminal 50 may use a public line.

[0075] Each position detection sensor 20 of Modification Example 1 acquires user information regarding the user from a transmitter 55 possessed by the user existing in the space 5 and detects the position of the user. Specifically, each position detection sensor 20 of Modification Example 1 communicates with the transmitter 55 in addition to communicating with the power storage device 30. The transmitter 55 transmits a beacon including a device identifier for identifying the transmitter 55.

[0076] When each position detection sensor 20 receives identification information in communication with the power storage device 30, it transmits to the server 10 the detection result information including, in addition to the battery identifier and the sensor identifier, first intensity information indicating the reception intensity of the identification information. When each position detection sensor 20 receives remaining amount information in communication with the power storage device 30, it transmits to the server 10 the received remaining amount information including the sensor identifier. When each position detection sensor 20 receives a beacon in communication with the transmitter 55, it transmits to the server 10 device detection result information including the device identifier, the sensor identifier, and second intensity information indicating the reception intensity of the beacon included in the received beacon.

[0077] As shown in FIG. 4, the server 10A of Modification Example 1 as the management system 2 includes a communication unit 11, a storage unit 12, and a control unit 13A.

[0078] The server 10A has, for example, a computer system having a processor and a memory. Then, by the processor executing a program stored in the memory, the computer system functions as the control unit 13A. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be provided by being recorded on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0079] The storage unit 12 of Modification Example 1 stores, in addition to the information shown in the embodiment, each of a plurality of device identifiers in association with information (for example, a telephone number, an email address) regarding the information terminal 50 used by the user who uses the transmitter 55 to which the device identifier is assigned.

[0080] The control unit 13A of Modification Example 1 has an acquisition unit 131, a determination unit 132, and a notification unit 133A.

[0081] When there is a target battery among the plurality of storage batteries 31, the notification unit 133A notifies the information terminal 50 of a user who uses the power storage device 30 having the target battery of the arrangement relationship information and the remaining amount relationship information for the target battery. Specifically, the notification unit 133A identifies at least one user who is using the target battery based on the positions of one or more users detected by the position detection sensor 20, and notifies the at least one user of the arrangement relationship information and the remaining amount relationship information. More specifically, the notification unit 133A identifies at least one user who is using the target battery based on the positions of one or more users obtained from one or more user information, and notifies the at least one user of the arrangement relationship information and the remaining amount relationship information.

[0082] The notification unit 133A identifies the position of the power storage device 30 based on the first intensity information included in the detection result information including the battery identifier of the power storage device 30 having the target battery.

[0083] The notification unit 133A identifies the position of the user of the target battery. More specifically, the notification unit 133A acquires one or more device detection result information that matches the sensor identifier included in the detection result information including the battery identifier of the power storage device 30 having the target battery. The notification unit 133A identifies at least one user who is within the detection range of the position detection sensor 20 corresponding to the sensor identifier and who uses the power storage device 30 whose position has been identified, based on the second intensity information included in each of the one or more acquired device detection result information. Here, the "at least one user who uses the power storage device 30 whose position has been identified" is a user whose distance from the power storage device 30 whose position has been identified is equal to or less than a predetermined distance. For example, the notification unit 133A identifies the positions of one or more transmitters 55 based on the second intensity information included in each of the one or more acquired device detection result information. The notification unit 133A identifies at least one transmitter 55 among the one or more transmitters 55 whose positions have been identified and whose distance from the power storage device 30 whose position has been identified is equal to or less than a predetermined value.

[0084] The notification unit 133A transmits notification information to all at least one user who uses the power storage device 30 having the target battery. Specifically, the notification unit 133A acquires, from the storage unit 12, information related to the information terminal 50 of at least one user who uses each of the specified at least one transmitter 55 based on the device identifier of each of the specified at least one transmitter 55. The notification unit 133A transmits the notification information to the information terminal 50 of at least one user who uses each of the specified at least one transmitter 55, that is, at least one information terminal 50, based on the information related to the information terminal 50 of at least one user. Here, the arrangement relationship information included in the notification information includes information representing the position of the power storage device 30 including the target battery, which is the position specified by the notification unit 133A.

[0085] The awarding unit 134 awards an incentive to a user who has charged the target battery among at least one user to whom the notification unit 133A has notified the notification information including the arrangement relationship information and the remaining amount relationship information. When the awarding unit 134 receives charging start information indicating that charging has started from one of the at least one information terminal 50 to which the notification unit 133A has transmitted the notification information, the awarding unit 134 performs an incentive awarding process of giving an incentive to the user of the information terminal 50 that has transmitted the charging start information. Here, the incentive is, for example, points corresponding to the consideration for receiving a service. Or, when the power storage device 30 is used in the office, the incentive is an evaluation point for the user in terms of work.

[0086] The information terminal 50 has, for example, a computer system having a processor and a memory. Then, when the processor executes a program stored in the memory, the computer system functions as the information terminal 50. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be recorded and provided on a recording medium such as a memory card, or may be provided through an electric communication line such as the Internet.

[0087] When the information terminal 50 receives notification information from the server 10A, it notifies the user. For example, the information terminal 50 displays the message included in the notification information. At this time, the information terminal 50 displays the position of the power storage device 30 including the target battery based on the information indicating the position of the power storage device 30 including the target battery included in the arrangement relationship information. When the information terminal 50 receives an input indicating the start of charging by a user operation, it transmits charging start information to the server 10A via the network NT1.

[0088] Next, the operation of the server 10A in Modification 1 will be described with reference to FIG. 5. Here, the operation of the server 10A after performing the acquisition process and the determination process shown in FIG. 3 will be described.

[0089] The notification unit 133A identifies the position of the target battery (step S101). Specifically, the notification unit 133A identifies the position of the power storage device 30 based on the first intensity information of the detection result information including the battery identifier of the power storage device 30 having the target battery.

[0090] The notification unit 133A identifies the position of the user of the target battery (step S102). Specifically, the notification unit 133A acquires one or more device detection result information that matches the sensor identifier included in the detection result information about the target battery. The notification unit 133A identifies at least one user who exists within the detection range of the position detection sensor 20 corresponding to the sensor identifier and uses the power storage device 30 whose position has been identified based on the second intensity information included in each of the one or more acquired device detection result information. The notification unit 133A identifies at least one transmitter 55 among the one or more transmitters 55 whose positions have been identified and whose distance from the power storage device 30 whose position has been identified is equal to or less than a predetermined value.

[0091] The notification unit 133A transmits notification information to all at least one user who uses the power storage device 30 having the target battery (step S103). The notification unit 133A transmits notification information to all at least one information terminal 50 used by each of at least one user who uses the power storage device 30 having the target battery.

[0092] The notification unit 133A acquires charging start information indicating the start of charging from one of the at least one information terminal 50 that has transmitted the notification information (step S104).

[0093] The notification unit 133A performs an incentive giving process of giving an incentive to the user of the information terminal 50 that has transmitted the acquired charging start information (step S105).

[0094] (5.2) Modification Example 2 The server 10 may transmit the notification information to the administrator terminal 60 used by the administrator of the facility or space 5 as a device other than the power storage device 30 having the target battery. Here, the administrator terminal 60 is, for example, a smartphone, a tablet terminal, or a personal computer.

[0095] The system configuration of the battery management system 1B according to Modification Example 2 is shown in FIG. 6. Hereinafter, the description will focus on the points different from the embodiment. Note that the same reference numerals are given to the same components as those in the embodiment, and the description thereof will be omitted as appropriate.

[0096] As shown in FIG. 6, the battery management system 1B of Modification Example 2 includes a server 10B as a management system 2 and scanners 21 and 22 as one or more (two in the illustrated example) position detection sensors 20.

[0097] The server 10B is configured to be communicable with one or more position detection sensors 20 and the administrator terminal 60 via the network NT1.

[0098] As shown in FIG. 6, the server 10B of Modification Example 2 as the management system 2 includes a communication unit 11, a storage unit 12, and a control unit 13B.

[0099] Server 10B has, for example, a computer system having a processor and a memory. Then, by the processor executing a program stored in the memory, the computer system functions as the control unit 13B. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be provided recorded on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0100] The control unit 13B of Modification 2 has an acquisition unit 131, a determination unit 132, a notification unit 133B, and a schedule creation unit 135.

[0101] The schedule creation unit 135 creates a charging schedule for periodically charging each of the plurality of storage batteries 31 so that the remaining amount does not become less than a predetermined value. For example, the schedule creation unit 135 estimates the time (date and time) when the remaining amount becomes less than the predetermined value from the change in the remaining amount in time series based on the remaining amount information corresponding to the storage battery 31 for each storage battery 31. The schedule creation unit 135 schedules to perform charging before the estimated time, for example, a predetermined time (1 hour before) before the estimated time. That is, the schedule creation unit 135 determines the time to start charging (charging start time) for each storage battery 31. The schedule creation unit 135 creates schedule information including the charging start times of all the scheduled storage batteries 31.

[0102] When there is a target storage battery among the plurality of storage batteries 31, the notification unit 133B notifies the administrator terminal 60 of the arrangement relationship information and the remaining amount relationship information for the target storage battery. Further, the notification unit 133B notifies the administrator terminal 60 of the schedule information related to the charging schedule, that is, the schedule information created by the schedule creation unit 135.

[0103] The administrator terminal 60 has, for example, a computer system having a processor and a memory. Then, by the processor executing a program stored in the memory, the computer system functions as the administrator terminal 60. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be provided recorded on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0104] When the administrator terminal 60 receives notification information and schedule information from the server 10B via the network NT1, it notifies the administrator. For example, the administrator terminal 60 displays a message indicating that charging of the target storage battery is necessary, which is included in the notification information. Further, the administrator terminal 60 displays a schedule regarding the charging of each storage battery based on the schedule information.

[0105] When a message indicating that charging of the target storage battery is necessary is displayed, the administrator performs charging on the target storage battery. Also, when a schedule regarding the charging of each storage battery is displayed, the administrator performs charging according to the charging start time for each storage battery 31. In addition, when the power storage device 30 has a function of automatically charging the storage battery 31 when the set time arrives, the administrator sets the charging start time for each storage battery 31 in the corresponding power storage device 30.

[0106] In Modification Example 2, the server 10B may obtain detection result information including intensity information representing the reception intensity of the identification information from the position detection sensor 20. In this case, similar to Modification Example 1, the notification unit 133B of the server 10B specifies the positions of the respective power storage devices 30 based on the intensity information corresponding to the identification information of each power storage device 30. Similar to Modification Example 1, the notification unit 133B includes, in the arrangement relationship information, information representing the position of the power storage device 30 including the target storage battery at the position specified by the notification unit 133B, and transmits notification information including the arrangement position relationship information and the remaining amount relationship information to the administrator terminal 60. The administrator terminal 60 displays the message included in the notification information and displays the position of the power storage device 30 including the target storage battery based on the information representing the position of the power storage device 30 included in the arrangement relationship information.

[0107] (5.3) Modification Example 3 The server 10C as the management system 2 according to Modification Example 3 is different from the embodiment in that it specifies the position of the target storage battery in cooperation with BIM (Building Information Modeling) data.

[0108] Hereinafter, the description will focus on the points different from the embodiment. Note that the same components as those in the embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0109] As shown in FIG. 7, the server 10C of Modification Example 3 includes a communication unit 11, a storage unit 12, and a control unit 13C.

[0110] The server 10C has, for example, a computer system having a processor and a memory. Then, when the processor executes a program stored in the memory, the computer system functions as the control unit 13C. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be recorded and provided on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0111] In addition to the information shown in the embodiment, the storage unit 12 of Modification 3 stores BIM data. In Modification 3, the BIM data includes an indoor map related to the layout of the space 5 (indoors of the facility).

[0112] The control unit 13C includes an acquisition unit 131, a determination unit 132, a notification unit 133C, and a position identification unit 136.

[0113] The position identification unit 136 identifies the positions of the plurality of storage batteries 31 using the indoor map and the detection result information corresponding to each of the plurality of storage batteries 31. In Modification 3, similar to Modification 1, the detection result information includes intensity information representing the reception intensity of the reception intensity of the identification information.

[0114] The position identification unit 136 calculates the distance from the position detection sensor 20 that has received the identification information to the storage device 30 (storage battery 31 thereof) that has transmitted the identification information based on the intensity information. The position identification unit 136 uses the calculated distance and the indoor map to identify the position where the storage device 30 (storage battery 31 thereof) is arranged on the layout of the space 5. For example, the position identification unit 136 uses the calculated distance and the indoor map to identify that the corresponding storage device 30 is arranged on the desk near the window among the plurality of desks.

[0115] The notification unit 133C notifies the position identified by the position identification unit 136 as arrangement relation information. That is, when there is a target storage battery, the notification unit 133C notifies notification information including the position of the target storage battery identified by the position identification unit 136 as the arrangement position of the target storage battery as arrangement relation information. In Modification 3, the notification unit 133C transmits the notification information to the administrator terminal 60 (see FIG. 6) of the administrator.

[0116] Since the server 10C as the management system 2 of Modification 3 notifies the administrator terminal 60 of the notification information included as the arrangement relation information, it is possible to assist the administrator in identifying and charging the storage battery 31 (storage device 30) with a small remaining amount.

[0117] Further, the server 10C may notify the information terminal 50 of the notification information included as the arrangement relationship information. In this case, since the server 10C notifies the information terminal 50 of the notification information included as the arrangement relationship information, a user who is trying to use the power storage device 30 and searching for the power storage device 30 can avoid the battery 31 with a small remaining amount, that is, can use the power storage device 30 having a battery 31 with a large remaining amount. When notifying the user who is searching for the battery 31, the server 10C may present information on using the battery with the largest remaining capacity closest to the user.

[0118] (5.4) Modification Example 4 In the above embodiment, it is configured that the predetermined value is a value corresponding to the amount of power that enables the battery 31 to supply power to the device for a predetermined period when power from the commercial power supply is not supplied. However, the configuration is not limited to this. The predetermined value may be a value corresponding to the full charge of the battery. For example, the predetermined value may be a value representing full charge.

[0119] In this case, the usage information acquisition unit 131b of the acquisition unit 131 acquires information related to the discharge state as usage information from each power storage device 30 (battery 31). The information related to the discharge state is, for example, information indicating that there is a device using the power of the battery 31, that is, information indicating that power is being output from at least one of the first output unit 34 and the second output unit 42.

[0120] The notification unit 133 notifies discharge state information regarding the discharge state of the target battery based on the usage information (information related to discharge) of the target battery instead of the remaining amount relationship information. Here, the discharge state information is information indicating whether the target battery is in use or not in use.

[0121] Thereby, the user can know the battery that is not in use.

[0122] Further, Modification 4 and the embodiment may be combined. That is, the acquisition unit 131 acquires position information regarding the position of each of the plurality of portable storage batteries 31 arranged in the space 5 and usage information regarding the usage state from each of the plurality of storage batteries 31. The notification unit 133 notifies, when there is a target storage battery among the plurality of storage batteries 31 whose remaining amount is equal to or less than a predetermined value, at least one of the arrangement relationship information and at least one of the remaining amount relationship information and the discharge state information. Here, the position relationship information is information regarding the arrangement position of the target storage battery based on the position information. The remaining amount relationship information is information regarding the remaining amount of the target storage battery based on the usage information (remaining amount information included therein) of the target storage battery. The discharge state information is information regarding the discharge state of the target storage battery based on the usage information (information regarding the usage state included therein) of the target storage battery.

[0123] (5.5) Modification 5 In Modification 5, a power supply unit 70 that supplies power to the storage battery 31 is provided in the space 5, and the point that the power supply unit 70 communicates with the position detection sensor 20 is different from the embodiment.

[0124] The system configuration of the storage battery management system 1D according to Modification 5 is shown in FIG. 8. Hereinafter, the description will focus on the points different from the embodiment. Note that the same components as those in the embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0125] As shown in FIG. 8, the storage battery management system 1D of Modification 5 includes a server 10D as a management system 2 and scanners 21 and 22 as one or more (two in the illustrated example) position detection sensors 20.

[0126] The power supply unit 70 provided in the space 5 is an outlet that charges the storage battery 31 of the power storage device 30. The power supply unit 70 includes a plurality of charging spots 71. The plurality of charging spots 71 are insertion ports of plugs provided in the outlet and are connected to a commercial power supply. That is, the charging spot 71 charges the storage battery 31. Note that in Modification 5, the power supply unit 70 is configured to include a plurality of charging spots 71, but is not limited to this configuration. The power supply unit 70 may be configured to include one charging spot 71.

[0127] The power supply unit 70 is configured to be communicable with a plurality of position detection sensors 20. The power supply unit 70 transmits a power supply identifier, which is an identifier stored in advance and used to identify the power supply unit 70, to one of the plurality of position detection sensors 20.

[0128] Furthermore, the power supply unit 70 transmits spot information including a plurality of spot usage information items each representing the usage status of a corresponding one of the plurality of charging spots 71 to at least one of the plurality of position detection sensors 20. The spot information further includes a plurality of spot numbers assigned one-to-one to the plurality of charging spots 71 and the power supply identifier. In the spot information, the plurality of spot usage information items and the plurality of spot numbers are associated with each other one-to-one. The power supply unit 70 associates spot usage information indicating "in use" as the usage status with the spot number of the charging spot 71 to which a plug is connected among the plurality of charging spots 71. The power supply unit 70 associates spot usage information indicating "not in use" as the usage status with the spot number of the charging spot 71 to which no plug is connected among the plurality of charging spots 71.

[0129] The plurality of position detection sensors 20 in Modification 5 periodically receive the power supply identifier transmitted from the power supply unit 70. The position detection sensor 20 that has received the power supply identifier periodically transmits power supply detection information including the power supply identifier, the reception signal strength at the time of receiving the power supply identifier, and the sensor identifier for identifying the position detection sensor 20 to the server 10D.

[0130] The plurality of position detection sensors 20 receive the spot information transmitted from the power supply unit 70. The position detection sensor 20 that has received the spot information transmits the spot information to the server 10D.

[0131] The server 10D is configured to be communicable with the plurality of position detection sensors 20 via the network NT1.

[0132] As shown in FIG. 8, the server 10D of Modification Example 5 as the management system 2 includes a communication unit 11, a storage unit 12, and a control unit 13D.

[0133] The server 10D has, for example, a computer system having a processor and a memory. Then, by the processor executing a program stored in the memory, the computer system functions as the control unit 13D. The program executed by the processor is recorded in advance in the memory of the computer system here, but it may be provided by being recorded on a recording medium such as a memory card, or may be provided through a telecommunication line such as the Internet.

[0134] The control unit 13D has an acquisition unit 131D, a determination unit 132, and a notification unit 133. The acquisition unit 131D has a detection result acquisition unit 131a, a usage information acquisition unit 131b, a power source position acquisition unit 131c, and a spot usage information acquisition unit 131d.

[0135] The power source position acquisition unit 131c acquires power source information representing the position of the power source that supplies power in the space 5. The power source position acquisition unit 131c receives power supply detection information from a plurality of position detection sensors 20 via the communication unit 11. The power source position acquisition unit 131c determines the position of the power supply unit 70 included in the power supply detection information as the positions of a plurality of charging spots 71 that are the power sources included in the power supply unit 70 based on the installation position of the position detection sensor 20 corresponding to the sensor identifier included in the power supply detection information and the received signal strength included in the power supply detection information, and acquires power source information representing the positions of the plurality of charging spots 71 that are the power sources.

[0136] The spot usage information acquisition unit 131d acquires usage information representing the usage status of the charging spots 71. The spot usage information acquisition unit 131d receives spot information from a plurality of position detection sensors 20 via the communication unit 11. The spot usage information acquisition unit 131d acquires spot usage information corresponding one-to-one to the plurality of charging spots 71 included in the spot information.

[0137] When the notification unit 133 notifies the arrangement relationship information and the remaining amount relationship information, it further notifies the positions of the plurality of charging spots 71 represented by the power source information acquired by the power source position acquisition unit 131c, that is, the positions of the power supply units 70, and the usage status of the plurality of charging spots 71 represented by the spot usage information acquired by the spot usage information acquisition unit 131d.

[0138] Among the plurality of position detection sensors 20, the power storage device 30 that has received the arrangement relationship information, the remaining amount relationship information, the position of the power supply unit 70 (the positions of the plurality of charging spots 71), and the usage status of the plurality of charging spots 71 from one position detection sensor 20 performs a notification process.

[0139] Here, in Modification 5, it is preferable that the power storage device 30 includes a display unit. In the notification process, the power storage device 30 superimposes information representing the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and information representing the usage status of the plurality of charging spots 71 on an image representing the area of the space 5 and displays the result on the display unit.

[0140] In this case, when the server 10D notifies the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and the usage status of the plurality of charging spots 71, it may notify information of an image in which information representing the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and information representing the usage status of the plurality of charging spots 71 are superimposed on an image representing the area of the space 5. Alternatively, the power storage device 30 stores in advance an area image representing the area of the space 5, and when it receives the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and the usage status of the plurality of charging spots 71, it superimposes information representing the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and information representing the usage status of the plurality of charging spots 71 on the area image and displays the result on the display unit.

[0141] Note that Modification 5 may be applied to Modifications 1 and 2. That is, the information terminal 50 may display an image in which information indicating the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and information indicating the usage status of the plurality of charging spots 71 are superimposed on an image representing the area of the space 5. Alternatively, the administrator terminal 650 may display an image in which information indicating the position of the power supply unit 70 (the positions of the plurality of charging spots 71) and information indicating the usage status of the plurality of charging spots 71 are superimposed on an image representing the area of the space 5.

[0142] Further, it is not essential that the acquisition unit 131D has both the power supply position acquisition unit 131c and the spot usage information acquisition unit 131d. The acquisition unit 131D may be configured to have either the power supply position acquisition unit 131c or the spot usage information acquisition unit 131d. That is, the acquisition unit 131D is configured to have at least one of the power supply position acquisition unit 131c and the spot usage information acquisition unit 131d.

[0143] In Modification 5, the insertion port provided in the power supply unit 70 (electrical outlet) is used as the charging spot 71, but the configuration is not limited to this. The power supply unit 70 (electrical outlet) may be used as the charging spot. In this case, when there is at least one unused insertion port in the power supply unit 70, the power supply unit 70 transmits spot information including usage information indicating unused, the spot number of the unused insertion port, and the power supply identifier to one of the plurality of position detection sensors 20. When there is no unused insertion port in the power supply unit 70, the power supply unit 70 transmits spot information including usage information indicating in use and the power supply identifier to one of the plurality of position detection sensors 20.

[0144] (5.6) Modification 6 The following are the listed modifications.

[0145] In the embodiment, it is assumed that a plurality of power storage devices 30 are arranged within the detection range of the position detection sensor 20. However, even if only one power storage device 30 is arranged within the detection range, the battery management system 1 of the present disclosure is applicable.

[0146] In the embodiment, the power storage device 30 is configured to communicate directly with the position detection sensor 20, but is not limited to this configuration. The power storage device 30 may communicate with the position detection sensor 20 via a power supply device 40 having a communication function.

[0147] In the embodiment, the power storage device 30 is configured to transmit the remaining amount information to the server 10 via the position detection sensor 20 and the network NT1, but is not limited to this configuration. The power storage device 30 may transmit the remaining amount information to the server 10 without passing through the position detection sensor 20.

[0148] (Other Modifications) The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. Further, functions similar to those of the management system 2 may be embodied by a battery management method, a computer program, or a non-transitory recording medium recording the program.

[0149] The battery management method of the battery management system 1 according to one aspect includes an acquisition step and a notification step. The acquisition step acquires position information regarding the position of each of a plurality of portable batteries 31 arranged in the space 5 and usage information regarding the usage state from each of the plurality of batteries 31. The notification step, when there is a target battery among the plurality of batteries 31 whose remaining amount is equal to or less than a predetermined value, notifies at least one of arrangement relationship information regarding the arrangement position of the target battery based on the position information, remaining amount relationship information regarding the remaining amount of the target battery based on the usage information of the target battery, and discharge state information regarding the discharge state of the target battery based on the usage information of the target battery. A program according to one aspect is a program for causing a computer system to function as the above-described battery management system 1 or the battery management method of the battery management system 1.

[0150] The execution entity of the battery management system 1 or the battery management method of the battery management system 1 in the present disclosure includes a computer system. The computer system has a processor and a memory as hardware. By the processor executing a program recorded in the memory of the computer system, the functions as the execution entity of the battery management system 1 or the battery management method of the battery management system 1 in the present disclosure are realized. The program may be pre-recorded in the memory of the computer system, or may be provided through a telecommunication line. Further, the program may be provided by being recorded on a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). Here, integrated circuits such as the IC or LSI mentioned here have different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Further, for an FPGA (Field-Programmable Gate Array) programmed after the manufacture of the LSI, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit section inside the LSI, it can also be adopted as a processor. The plurality of electronic circuits may be integrated on one chip, or may be provided distributed on a plurality of chips. The plurality of chips may be integrated in one device, or may be provided distributed on a plurality of devices.

[0151] Also, it is not an essential configuration of the management system 2 that a plurality of functions in the management system 2 are integrated in one housing, and the components of the management system 2 may be provided distributed in a plurality of housings. Further, at least some functions of the management system 2 may be realized by cloud (cloud computing) or the like.

[0152] (Summary) As described above, the battery management system (1, 1A, 1B, 1D) of the first aspect includes an acquisition unit (131) and a notification unit (133). The acquisition unit (131, 131D) acquires position information regarding the position of each of a plurality of portable batteries (31) arranged in the space (5) and usage information regarding the usage state from each of the plurality of batteries (31). The notification unit (133, 133A, 133B, 133C) notifies, when there is a target battery among the plurality of batteries (31) whose remaining amount is equal to or less than a predetermined value, at least one of the arrangement relationship information, the remaining amount relationship information, and the discharge state information.
