It is a system to do. The power storage system 10 has a function of suppressing the use of a storage battery attached to the power storage device 100 until a predetermined activation is performed. This activation is authentication for confirming that a setting operation at the time of installing the power storage device 100 or a replacement operation of a storage battery in the power storage device 100 is performed by a contractor that satisfies a predetermined standard. The operation of this certification is based on the premise that a contractor who satisfies a predetermined standard possesses the contractor identification information (information that identifies the contractor and succeeds in authentication) issued by a predetermined accreditation body. And

  As shown in FIG. 1, the power storage system 10 includes a power storage device (battery unit) 100 installed in a customer facility 20, a power conditioner 200, and an operation terminal 300. The customer facility 20 has a distribution board 40 that distributes power (system power) received from the power system, which is equipment of an electric power company, etc., to the load 50 and the like. The load 50 collectively represents electrical devices and the like in the customer facility 20, and each electrical device and the like is connected to one of a plurality of branch circuits in the distribution board 40. Note that the customer facility 20 may include a power generation device that performs solar power generation or the like, in which case the power generation device is connected to the distribution board 40.

  The power storage device (battery unit) 100 includes, for example, a mounting unit for mounting a storage battery (storage battery 109a to 109c or the like) such as a lithium ion secondary battery or a lead storage battery, a control circuit for controlling the storage battery, and the like. The power storage device 100 is used for, for example, efficiently using power by storing and discharging or preparing for a power failure. Each of the storage batteries 109a to 109c is, for example, a replaceable unit among secondary battery units such as a battery cell, a battery module that is an assembly of battery cells, and a battery pack (battery unit) that is an assembly of battery modules. Any of those used may be used. Here, for convenience of explanation, the storage batteries 109a to 109c are shown, but the number of storage batteries may be any number. In addition, the storage battery identification information which identifies the storage battery is defined for every unit of the exchangeable storage battery, for example, storage battery identification information is hold | maintained so that it can be read from the outside about every unit. Here, the control circuit for controlling the storage battery includes a computer having a memory, a processor (microprocessor), a communication interface (I / F), an input I / F, and the like. The memory is a ROM that stores a program and data in advance, a RAM that is used to store data or the like when the program is executed, and may include, for example, a nonvolatile memory. The processor performs various processes by controlling, for example, the communication I / F by executing a program (control program or the like) stored in the memory. The communication I / F is a communication circuit for transmitting a signal to / from the power conditioner 200 through a signal line, for example. The input I / F is an input device such as a touch panel, a keyboard, and a switch, for example, and may have any configuration as long as input data can be acquired.

  The power conditioner 200 is connected to the power storage device 100 and the distribution board 40, and is a power conversion device that performs conversion between DC power and AC power. The power conditioner 200 is configured to charge (that is, input current) and discharge (that is, output current) the power storage device 100 (specifically, the storage batteries 109a to 109c) according to a predetermined algorithm. Take control. Under this control, the power conditioner 200 receives, for example, the system power distributed from the distribution board 40 and charges the power storage device 100, and the electric power discharged from the power storage device 100 is supplied to the load 50 via the distribution board 40. To supply. When the power conditioner 200 receives the instruction information from the operation terminal 300, the power conditioner 200 determines the control content related to charging and discharging of the power storage device 100 according to the instruction information, and performs control. The power conditioner 200 performs storage battery input / output processing (described later) for control related to input / output (charging / discharging) of the storage battery. The input / output of current to the storage battery is to input current to the storage battery (charging the storage battery) or to output current from the storage battery (discharge of the storage battery).

  The operation terminal 300 is a terminal (for example, a remote controller) having a function of receiving an operation of a user (for example, a power consumer) and transmitting instruction information corresponding to the operation to the power conditioner 200. The operation terminal 300 is a terminal connected to the power conditioner 200 in a wired manner, or may be a terminal capable of wireless communication with the power conditioner 200. That is, it may be a computer such as a tablet or a smartphone having a user I / F and having portability. In this case, for example, a computer such as a smartphone executes an operation application program for receiving a user operation and transmitting instruction information to the power conditioner 200. The instruction information is information for instructing the power conditioner 200 to input / output a current to / from the storage battery (power storage device 100), for example, an instruction to set the discharge state or an instruction to set the storage state. The instruction information may be information for selectively instructing various algorithms (operation modes) for charge / discharge control determined in advance for the power storage device 100, for example.

  In the power storage system 10 having such a configuration, the power storage device 100 has a function relating to the authentication of the installer for activation, which is a premise for using the storage battery. In order to realize this function, the power storage device 100 having the above-described hardware configuration is functionally configured as shown in FIG. 1, in terms of function, the installer identification information acquisition unit 110, the authentication unit 120, the storage battery identification information acquisition unit 130, and the recording Unit 140 and control unit 150.

  The installer identification information acquisition unit 110 is realized by, for example, an input I / F, a processor that executes a program, and the like. The contractor identification information acquisition unit 110 receives the input operation by the contractor who has performed the setting work (installation work), replacement work, and the like related to the storage battery, and receives the input operation by the input I / F. It has the function to acquire.

  The authentication unit 120 is realized by a processor or the like that executes a program. The authentication unit 120 has a function of authenticating the installer identification information acquired by the installer identification information acquisition unit 110. Authentication is an alternative determination as to whether or not a predetermined authentication standard (condition) that is set in advance is satisfied. It is said that the authentication is successful when it is determined that the condition is satisfied, and that it is determined that the condition is not satisfied. Say that authentication fails. The authentication may be executed by any known authentication method, and any predetermined authentication standard (condition) may be defined. For example, the predetermined authentication standard (condition) is that the code (bit data) indicated by the builder identification information has regularity that can be verified by a predetermined operation, or that the code is valid that is set in the authentication unit 120 in advance. It exists in a list that lists codes. In addition, in order for authentication to function effectively, the installer identification information (legitimate installer identification information that succeeds in authentication) issued by a predetermined accreditation body and held by the installer is not easily known to a third party. It is useful to operate as follows.

  The storage battery identification information acquisition unit 130 has a function of acquiring storage battery identification information of each of the storage batteries 109a to 109c attached to the attachment unit in the power storage device (battery unit) 100. The storage battery identification information acquisition part 130 reads the storage battery identification information about each of the storage batteries 109a-109c via a mounting part, for example by the processor which performs a program. The storage battery identification information acquired by the storage battery identification information acquisition unit 130 can be recorded as part of storage battery management information for managing each storage battery mounted in the power storage device 100, for example. FIG. 2 shows an example of storage battery management information. In the storage battery management information, for example, the storage battery identification information of each of the storage batteries 109a to 109c corresponds to the management serial numbers 1 to 3 on a one-to-one basis. The storage battery management information is used, for example, in the power storage device 100 to manage the mounting position, state, usage history (usage period, etc.), storage temperature, charge amount, and the like of each storage battery.

  The recording unit 140 is realized by a memory, a processor that executes a program, and the like. When the authentication unit 120 succeeds in authentication, the recording unit 140 uses the storage battery identification information of each of the storage batteries 109a to 109c attached to the power storage device 100 acquired by the storage battery identification information acquisition unit 130 as authenticated storage battery information. It has a function of recording on a recording medium such as a nonvolatile memory. The authenticated storage battery information is management information indicating a storage battery (that is, an activated storage battery) that has become available due to successful authentication. FIG. 3 shows an example of authenticated storage battery information. The authenticated storage battery information indicates storage battery identification information of a storage battery that has been successfully authenticated, and, as illustrated in the figure, is associated with each of the storage battery identification information, and the installer identification information and authentication subject to authentication by the authentication unit 120 Date and time may be included. When the authenticated storage battery information includes the installer identification information and the like, for example, it becomes possible to specify the installer as necessary.

  The control unit 150 is realized by a communication I / F, a processor that executes a program, and the like. The control unit 150 performs control related to input / output of current by the power conditioner 200 with respect to the storage battery attached to the power storage device 100 (control related to whether input / output is allowed) according to the result of authentication by the authentication unit 120. Has the function to perform. The control unit 150 performs control so as not to allow current input / output by the power conditioner 200 to the storage battery until the authentication unit 120 succeeds in authentication, for example. As a specific example of this control, the control unit 150 treats the case where the storage battery identification information of all the storage batteries attached to the power storage device 100 is recorded as the authenticated storage battery information as being authenticated, The other cases are treated as authentication is not successful. When the authentication is not successful (until the authentication is successful), the control unit 150 allows an input / output of current to the storage batteries 109a to 109c attached to the power storage device 100. Is not transmitted to the power conditioner 200. The control unit 150 performs control (control processing) for transmitting an allowable signal to the power conditioner 200 after the authentication is successful. The transmission of the allowance signal indicates that the input / output of the current by the power conditioner 200 to the storage battery is permitted, and conversely, not transmitting the allowance signal indicates that the input / output of the current by the power conditioner 200 to the storage battery is not allowed. Represent. The power conditioner 200 performs input / output to / from the storage battery as necessary when receiving the permission signal, but does not perform input / output to / from the storage battery when not receiving the permission signal. The power conditioner 200 transmits a signal for inquiring whether or not input / output is permitted repeatedly to the power storage device 100, and the power storage device 100 transmits a permission signal only when the authentication is successful as a response. It is good. The allowable signal may include, for example, information indicating an upper limit value of a current that can be input. For example, the power conditioner 200 may perform control related to input of a current according to the upper limit value.

(Operation)
Hereinafter, an example (operation example) of a control method in the power storage system 10 having the above-described configuration will be described.

  FIG. 4 is a flowchart illustrating an example of the authentication recording process in the power storage device 100. Hereinafter, the authentication recording process will be described with reference to FIG. When the storage battery is set or replaced, the installer performs an operation of inputting the installer identification information to the power storage device 100, and at this time, an authentication recording process is executed.

  The power storage device 100 acquires the installer identification information by the installer identification information acquisition unit 110 by receiving an input operation or the like by the installer (step S11).

  The authentication unit 120 authenticates the installer identification information acquired by the installer identification information acquisition unit 110 (step S12).

  When the authentication in step S12 is successful, the power storage device 100 acquires the storage battery identification information of each of the storage batteries 109a to 109c attached to the power storage device 100 by the storage battery identification information acquisition unit 130 (step S14). Subsequently, the storage unit 140 records each storage battery identification information as authenticated storage battery information (see FIG. 3) in association with the successful identification of the installer (step S15). In the case where authenticated storage battery information has already been recorded, for example, additional writing is performed in step S15. With this authenticated storage battery information, for each storage battery that has been attached to the power storage device 100, the installer who should have finally confirmed the installation status of the storage battery and the like can be identified.

  If authentication fails in step S12, power storage device 100 skips steps S14 and S15 and does not record authenticated storage battery information.

  FIG. 5 is a flowchart illustrating an example of a storage battery input / output process in the power conditioner 200. Hereinafter, the storage battery input / output process will be described with reference to FIG.

  The power conditioner 200 determines the input / output content of the current to the storage battery of the power storage device 100 based on the instruction information from the operation terminal 300 (step S21). For example, the power conditioner 200 has a time zone in which current is input to the storage battery, a time zone in which current is output from the storage battery, and the magnitude of these currents in accordance with the contents (for example, operation mode) indicated by the instruction information from the operation terminal 300. Determining etc.

  The power conditioner 200 determines whether an allowable signal can be received from the power storage device 100 when it is necessary to perform input / output to / from the storage battery of the power storage device 100 (step S22). When the permission signal is received, the power conditioner 200 executes input / output of current to / from the storage battery of the power storage device 100 (step S23). Further, when the permissible signal cannot be received, power conditioner 200 does not execute input / output of current to / from the storage battery of power storage device 100 until the permissible signal can be received.

  FIG. 6 is a flowchart illustrating an example of a control process in power storage device 100. Hereinafter, the control process will be described with reference to FIG. This control process is repeatedly executed, for example, continuously or in a relatively short cycle (for example, several seconds).

  The control unit 150 of the power storage device 100 determines whether or not the storage battery identification information of all the storage batteries attached to the power storage device 100 is included in the authenticated storage battery information recorded on the recording medium (step S31).

  When it is determined that the storage battery identification information of all the storage batteries is included in the authenticated storage battery information, the control unit 150 transmits (transmits) an allowable signal indicating that input / output is permitted to the power conditioner 200 (step S32). . Moreover, when it determines with one or more of the storage battery identification information of the storage battery with which the electrical storage apparatus 100 was mounted | worn being not contained in the authenticated storage battery information, the control part 150 does not transmit an allowance signal.

  As described above, in the power storage system 10, the power storage device 100 is authenticated unless the contractor authenticates the contractor and the installer who has performed the setting work or replacement work of the storage battery has not properly input the installer identification information to the power storage system 10. Thus, control is performed so as not to allow the use of the storage battery. Therefore, it can be suppressed that the storage battery is used in an inappropriate state. Inappropriate states include, for example, a state in which one or more storage batteries are not correctly installed in a proper position, a state in which one or more storage batteries are poor quality, excessively deteriorated, etc. It is in a state where it is placed in an environment where the temperature can be high or low beyond the limit. For example, if you operate with a predetermined accreditation body to give the installer identification information that succeeds in authentication for those who have sufficient expertise on storage batteries and perform construction using high-quality storage batteries, An appropriate operation of the power storage device 100 is maintained.

Further, the two-dimensional code printed on the certification card may represent the installer identification information and the address of the server 30. In this case, the authentication unit 420 accesses the server 30 using the address represented in the two-dimensional code. The server 30 may have an authentication function. In this case, the authentication unit 420 may perform authentication by transmitting the contractor identification information to the server 30 and receiving a response from the server 30 (that is, information indicating success or failure as an authentication result). Good. Further, the authentication unit 420 may perform authentication using the same method as the authentication unit 120 described in the first embodiment without accessing the server 30. For example, the information terminal 400 may download and update (update) an authentication application program that defines, for example, the processing content of the authentication unit 420 from a predetermined website or the like. On the specified website, update the application program for authentication provided as necessary in connection with the issuance of the contractor identification information by the specified accreditation body and the management related to the expiration of the validity period of the contractor identification information. obtain. In the case where the server 30 has an authentication function, the server 30 performs authentication in connection with the management related to the issuance of the contractor identification information and the expiration of the valid period of the contractor identification information by a predetermined authorized organization. The predetermined authentication standard (condition) to be used can be updated.

  The setting unit 460 has a function of transmitting setting information to the power storage device (battery unit) 102 when the authentication unit 420 succeeds in authentication related to the installer. The setting information may include the installer identification information acquired by the installer identification information acquisition unit 410. Communication between the information terminal 400 and the power storage device 102 is performed using short-range wireless communication such as Bluetooth (registered trademark) or wireless LAN (Local Area Network). The information terminal 400 may communicate with the power storage device 102 via the operation terminal 300 and the power conditioner 200.

  The power storage device (battery unit) 102 is a partial modification of the power storage device 100 described in Embodiment 1. The power storage device (battery unit) 102 includes a mounting unit for mounting a storage battery (storage batteries 109a to 109c and the like), a control circuit for controlling the storage battery, and the like. In addition, the storage battery identification information which identifies the storage battery is defined for every unit of the exchangeable storage battery, for example, storage battery identification information is hold | maintained so that it can be read from the outside about every unit. Here, the control circuit for controlling the storage battery includes a computer having a memory, a processor, a communication I / F, and the like.

  As shown in FIG. 12, the power storage device 102 has a storage battery identification information acquisition unit 130, a recording unit 140, and a control unit 150 in terms of functions.

  The storage battery identification information acquisition unit 130 has a function of acquiring storage battery identification information of each of the storage batteries 109a to 109c attached to the attachment unit in the power storage device (battery unit) 102. The storage battery identification information acquisition part 130 reads the storage battery identification information about each of the storage batteries 109a-109c via a mounting part, for example by the processor which performs a program. The storage battery identification information acquired by the storage battery identification information acquisition unit 130 can be recorded as a part of storage battery management information (see FIG. 2) for managing each storage battery mounted in the power storage device 102, for example.

  The recording unit 140 is realized by a memory, a processor that executes a program, a communication I / F, and the like. The recording unit 140 is attached to the power storage device 102 acquired by the storage battery identification information acquisition unit 130 when setting information (information related to activation) indicating successful authentication related to the installer is received from the information terminal 400. The storage battery identification information of each of the storage batteries 109a to 109c is recorded on a recording medium such as a nonvolatile memory as authenticated storage battery information. The authenticated storage battery information is information for management indicating a storage battery (that is, an activated storage battery) that has become available due to a successful authentication. When the setting information transmitted from the information terminal 400 includes the installer identification information, the authenticated storage battery information may include the installer identification information in association with each storage battery identification information as shown in FIG. The date and time when the power storage device 102 receives the setting information may be included as the authentication date and time.

  The control unit 150 is realized by a communication I / F, a processor that executes a program, and the like. The control unit 150 performs control related to input / output of current by the power conditioner 200 with respect to the storage battery attached to the power storage device 102 (whether or not to allow input / output) according to the result of the authentication related to the installer at the information terminal 400. A function of performing control according to the above. The control unit 150 performs control so as not to allow input / output of current to the storage battery by the power conditioner 200 until, for example, authentication related to the installer at the information terminal 400 is successful. As a specific example of this control, the control unit 150 recognizes that the storage battery identification information of all the storage batteries attached to the power storage device 102 has been recorded as authenticated storage battery information by the recording unit 140 and has been successfully authenticated. Otherwise, it is treated that authentication is not successful. When the authentication is not successful (until the authentication is successful), the control unit 150 allows an input / output of current to / from the storage batteries 109a to 109c attached to the power storage device 102. Is not transmitted to the power conditioner 200. After the authentication is successful, the control unit 150 performs a control process (see FIG. 6) for transmitting an allowance signal to the power conditioner 200.

(Operation)
Hereinafter, an example (operation example) of a control method in the power storage system 13 having the above-described configuration will be described.

  FIG. 13 is a flowchart illustrating an example of authentication setting processing in the information terminal 400. The authentication setting process will be described below with reference to FIG.

  When the storage battery is set or replaced, the installer operates the authentication application program on the information terminal 400 and performs an operation of photographing the two-dimensional code of the certification card. At this time, the installer identification information acquisition unit 410 of the information terminal 400 causes the imaging unit 405 to capture a two-dimensional code, and acquires the installer identification information by extracting from the two-dimensional code (step S61).

  The authentication unit 420 performs authentication by transmitting the installer identification information acquired by the installer identification information acquisition unit 410 to the server 30 and receiving a response from the server 30 (step S62).

  When the authentication in step S62 is successful (step S63), the setting unit 460 includes, for example, the contractor identification information in the power storage device (battery unit) 102, and indicates that the input / output of the storage battery is permitted (activation). Setting information indicating that the process is complete) is transmitted (step S64). If the authentication in step S62 fails, the setting unit 460 does not transmit setting information.

  FIG. 14 is a flowchart illustrating an example of a recording process in the power storage device 102. Hereinafter, the recording process will be described with reference to FIG.

  When the storage device 102 receives the setting information from the information terminal 400 (step S71), the storage battery identification information of each of the storage batteries 109a to 109c attached to the storage device (battery unit) 102 is stored by the storage battery identification information acquisition unit 130. Is acquired (step S72). Here, the description will be continued assuming that the setting information includes the installer identification information.

  The recording unit 140 of the power storage device 102 associates the storage battery identification information acquired in step S72 with the contractor identification information included in the setting information, and records the information as authenticated storage battery information (see FIG. 3) on the recording medium. (Step S73).

  The control unit 150 of the power storage device 102 executes the control process illustrated in FIG. 6 by referring to the authenticated storage battery information recorded on the recording medium by the above-described recording process. Moreover, the power conditioner 200 performs the storage battery input / output process shown in FIG.

  As described above, in the power storage system 13, when the installer who performed the construction related to the storage battery performs authentication using the information terminal 400 such as a smartphone, the use of the storage battery is permitted when the authentication is successful, and the authentication is not successful. Control that does not allow the use of the storage battery is performed. Therefore, it can be suppressed that the storage battery is used in an inappropriate state. For this reason, for example, a certification card that expresses, by a two-dimensional code, identification information of a contractor who has a sufficient expertise and who can successfully authenticate a person who uses a high-quality storage battery. If the operation is performed so that the power storage device 102 is given, proper operation of the power storage device 102 is maintained.

(Other embodiments, etc.)
As mentioned above, although the electrical storage system and the control method were demonstrated by Embodiment 1-4, it cannot be overemphasized that embodiment mentioned above is only an example and various changes, addition, omission, etc. are possible.

  The power conditioner and the power storage device (battery unit) shown in the above embodiment may have different casings or may be included in one casing. In the case of having separate enclosures, for example, the power conditioner and the power storage device may be arranged separately in the customer facility 20 outdoors (outside the building) and indoors. In the case where the power conditioner and the power storage device are included in the same casing, some hardware configurations (such as a processor and other circuits) may be shared with each other.

  In addition, the power storage device, power conditioner, or operation terminal shown in the above first to third embodiments may be provided with a communication function for accessing the server 30 shown in the fourth embodiment. It is good also to utilize. The server 30 described above may be realized by a plurality of computers provided with recording media and capable of communicating with each other, and each computer is installed at a location distant from each other and communicates with each other via a wide area network. May be.

  Moreover, in the above-mentioned Embodiment 2 and its modification, the control part 250 of the power conditioner 201 does not perform use (input / output) of the storage battery unless the installer is authenticated for all storage batteries. The example which controls and the example which controls so that a storage battery may be used will be shown, after the builder's certification | authentication is made | formed for every unit of the exchangeable storage battery. Similarly, control unit 150 of power storage device 100 may also be controlled so as to allow the use of a storage battery for each unit of the storage battery after the contractor has been authenticated. In addition, in the control unit 350 of the operation terminal 301, the instruction information may be transmitted so that the storage battery is designated and permitted to be used for each unit of the storage battery after the builder is authenticated.

  In the fourth embodiment, the information terminal 400 transmits the setting information to the power storage device when the authentication of the contractor is successful. This is a form in which the authentication function in the power storage device described in Embodiment 1 is shared by the information terminal 400. Similarly, the authentication function in the power conditioner shown in the second embodiment is shared by the information terminal 400, and the information terminal 400 transmits the setting information to the power conditioner when the authentication of the installer is successful. It is good. In this case, the information terminal 400 may transmit the setting information to the power conditioner via the operation terminal. Further, the information terminal 400 may transmit the setting information to both the power storage device and the power conditioner. Further, the authentication function in the operation terminal shown in the third embodiment may be shared by the information terminal 400, and the information terminal 400 may transmit the setting information to the operation terminal when the construction terminal is successfully authenticated. .

  In the fourth embodiment, the proof card shows an example in which the builder identification information is represented by a two-dimensional code. However, the builder identification information can be optically read by a one-dimensional barcode or other methods. It may be expressed as follows.

  Further, the authentication unit 420 of the information terminal 400 shown in the fourth embodiment may authenticate the contractor identification information without communicating with the server 30 as in the authentication unit 120 shown in the first embodiment.

  Moreover, in the above-mentioned embodiment, the example which acquires the storage battery identification information of a storage battery and includes it in the content of the authenticated storage battery information (refer FIG. 3) was shown. In addition to this, the storage battery identification information may not be used by indicating that the authenticated storage battery information has succeeded in authenticating the contractor who performed the installation work (storage battery setting work, etc.) of the power storage device. In this case, in the power storage system, control is performed so as not to allow input / output of current by the power conditioner to the storage battery until, for example, the authenticated storage battery information indicating that the installer has been successfully authenticated is recorded on the recording medium. Thereby, it can be suppressed that the storage battery is used in an inappropriate state.

  Further, the execution order of the processing procedures (the procedures shown in FIGS. 4 to 6, 8, 9, 11, 13, and 14) in the above-described power storage systems 10 to 13 is not necessarily limited to the order as described above. The execution order can be changed or a part thereof can be omitted without departing from the scope of the invention. Further, all or part of the processing procedure may be realized by hardware or may be realized by using software. For example, the power storage device (power storage unit), the power conditioner, or the operation terminal may be configured only by hardware (such as an electronic circuit) that does not include software (program). Note that the processing by software is realized by a processor included in each device executing a control program stored in a memory. Further, the control program may be recorded on a recording medium and distributed or distributed. For example, by installing the distributed control program in a computer and causing the processor to execute it, the computer performs all or part of the processing procedures shown in FIGS. 4 to 6, 8, 9, 11, 13, and 14. It becomes possible to make it.

  In addition, embodiments realized by arbitrarily combining the constituent elements and functions described in the above-described embodiments, modification modes, and the like are also included in the scope of the present invention.

As this control, as shown in the above-described embodiment, control whether or not current is input / output on the power conditioner side, or an allowance signal indicating that current input / output is allowed on the power storage device side is transmitted. In addition to the control of whether or not, the following control example is given. For example, depending on the result of authentication by the authentication unit, the relay on the storage battery side is turned off (OFF) so that no current can be input to or output from the storage battery, or the relay on the power conditioner side is similarly turned off. is there. Moreover, the control which interrupts | blocks communication between an electrical storage apparatus (storage battery) and a power conditioner may be sufficient. Further, the power storage device notifies the power conditioner that the remaining amount of the storage battery is 0, and the power conditioner recognizes that there is no remaining amount and controls the discharge.

  As a result, in order to perform authentication, it is possible to check whether or not a contractor who satisfies a predetermined standard has been constructed. Inappropriate setting work and replacement work are performed, and the storage battery is in an inappropriate state. Utilization can be suppressed.

  (2) For example, the control units 150, 250, and 350 control the power conditioners 200 for the storage batteries 109 a to 109 c attached to the battery units 100, 101, and 102 until the authentication units 120, 220, 320, and 420 succeed in authentication. Control may be performed so that current input / output by 201 is not allowed. Note that the control not to allow the input / output of current to the storage battery until the authentication is successful is a concept including the control not to input / output current to the storage battery until the authentication is successful. The control not to allow the input / output of the current to the storage battery until the authentication is successful is realized, for example, by the battery unit 100 not transmitting the permission signal to the power conditioner 200 until the authentication is successful, and the authentication is successful. This is realized by the power conditioner 201 not performing input / output of current to / from the storage battery until the operation terminal 301 performs the operation, or the operation terminal 301 does not transmit the instruction information to the power conditioner 200 until the authentication is successful.

  Thereby, since use of a storage battery is not permitted until it succeeds in a contractor's authentication, possibility that a storage battery will be used in an inappropriate state may be reduced. This is because it is possible to distinguish whether or not a contractor who satisfies a predetermined standard has been constructed by the authentication, and when a contractor who satisfies the standard performs the construction, the storage battery should be placed in an appropriate state.

  (3) For example, the storage systems 10 to 13 include storage battery identification information acquisition units 130, 230, and 330 that acquire storage battery identification information of the storage batteries 109a to 109c attached to the battery units 100, 101, and 102, and an authentication unit. When 120, 220, 320, 420 succeeds in authentication, the recording unit 140, 240, 340, which records the storage battery identification information of each storage battery attached to the battery unit as authenticated storage battery information on a recording medium, When the storage battery identification information of all the storage batteries attached to the battery unit is recorded as authenticated storage battery information, the control units 150, 250, and 350 are connected to the power conditioner 200 for each storage battery attached to the battery part. 201 is controlled so as to allow current input and output by 201, and the storage battery identification of one or more storage batteries mounted in the battery unit. If the information is not recorded as a trusted battery information may be controlled so as not to permit the input and output of current by the power conditioner for each storage battery mounted in the battery unit.

  Thereby, in the case where the storage battery (storage device) includes a storage battery that has not been successfully authenticated by the contractor (for example, a storage battery replaced by a contractor that does not satisfy a predetermined standard), Use is not allowed and the possibility of being used in an inappropriate state is reduced.

  (4) For example, the battery units 100, 101, and 102 are equipped with a plurality of storage batteries 109a to 109c, and the power storage systems 10 to 13 are storage battery identification information for acquiring storage battery identification information of each storage battery attached to the battery unit. When the acquisition units 130, 230, 330 and the authentication units 120, 220, 320, 420 succeed in the authentication, the storage battery identification information of each storage battery attached to the battery unit is recorded on the recording medium as the authenticated storage battery information. The storage units 140, 240, and 340, and the control units 150, 250, and 350 are storage batteries in which storage battery identification information of the storage battery is recorded as authenticated storage battery information among a plurality of storage batteries attached to the battery unit. Control is performed to allow current input and output by the power conditioners 200 and 201 to the storage battery, and storage battery identification information of the storage battery It may be controlled so as not to permit the input and output of current by the power conditioner for storage batteries that have not been recorded as a trusted battery information.

  Thereby, about the storage battery (for example, the storage battery etc. which the contractor which did not satisfy | fill the predetermined reference | standard which replaced | exchanged the predetermined reference | standard) among the some storage batteries with which the electrical storage part (electric storage apparatus) was mounted | worn is not successful. The use of each storage battery is not allowed. For this reason, the possibility that the storage battery is used in an inappropriate state is reduced.

  (5) For example, the battery units 100 and 102 include the control unit 150. The control unit 150 performs the above-described control with respect to the storage battery attached to the battery unit until the authentication units 120 and 420 succeed in authentication. It may be possible to perform control for transmitting an allowable signal to the power conditioner 200 after the authentication units 120 and 420 have succeeded in authentication without transmitting an allowable signal indicating that current input / output is permitted to the power conditioner 200.

  Thereby, the power conditioner 200 can distinguish whether it is in the state in which the input / output with respect to a storage battery is permitted by the presence or absence of transmission of a permission signal. For this reason, when the power conditioner 200 follows the allowable signal, the possibility that the storage battery is used in an inappropriate state is reduced.

  (6) For example, as described above, the control unit 250 does not cause the power conditioner 201 to input / output current to the storage batteries 109a to 109c attached to the battery unit 101 until the authentication unit 220 succeeds in authentication (that is, Neither input current to the storage battery nor output current from the storage battery), and input / output current to / from the storage batteries 109a to 109c attached to the battery unit 101 in the power conditioner 201 after the authentication unit 220 succeeds in authentication. Control may be performed.

  Thereby, since a storage battery is not used until it succeeds in a contractor's authentication, possibility that a storage battery will be used in an inappropriate state reduces.

  (7) For example, the power storage systems 10 to 13 include storage battery identification information acquisition units 130, 230, and 330 that acquire storage battery identification information of the storage batteries 109a to 109c attached to the battery units 100, 101, and 102, and an authentication unit. When 120, 220, 320, 420 succeeds in authentication, the storage battery identification information of each storage battery attached to the battery unit is associated with the authenticated worker identification information and recorded as authenticated storage battery information It is good also as providing the recording parts 140, 240, and 340 which record to.

  Thus, by referring to the recording medium, it is possible to identify the installer who performed the construction related to the storage battery.

  (8) For example, the power storage system 12 includes an operation terminal 301 that transmits instruction information instructing input / output of current to the storage batteries 109a to 109c to the power conditioner 200 according to an operation. The person identification information acquisition unit 310, the authentication unit 320, and the control unit 350 may be included, and the control unit 350 may suppress transmission of instruction information until the authentication unit 320 succeeds in authentication.

  Thus, the instruction information is not transmitted to the power conditioner 200 until the installer is successfully authenticated. Therefore, if the storage battery is not used until the power conditioner 200 receives the instruction information, the possibility that the storage battery is used in an inappropriate state is reduced.

  (9) For example, the power storage system 13 includes an information terminal 400 having a contractor identification information acquisition unit 410 and an authentication unit 420, and the information terminal 400 includes the photographing unit 405 and the authentication unit 420 when the authentication is successful. A setting unit 460 that transmits setting information regarding input / output of current to / from the storage battery is provided to at least one of the power conditioner and the battery unit, and the installer identification information acquisition unit 410 is an imaging target that represents the installer identification information (for example, The operator identification information may be obtained by photographing the certification card) by the photographing unit 405. The setting information indicates, for example, success of authentication related to the installer, and is information for controlling input / output of current to / from the storage battery (information related to activation).

  Thereby, the contractor who holds the certification card or the like representing the contractor identification information can use the storage battery by a relatively easy operation by performing authentication using the information terminal 400.

  (10) For example, the authentication unit 420 may perform authentication by communicating with the server 30 that manages predetermined installer identification information.

  Accordingly, the power storage system reflects the situation in which the server 30 manages the predetermined contractor identification information (for example, the latest situation as a result of addition, change, deletion, etc. of the contractor identification information to be managed). In this case, it is possible to perform authentication appropriately.

  (11) A control method according to one aspect of the present invention is a power storage system including battery units 100, 101, and 102 to which one or more storage batteries 109a to 109c are attached, and power conditioners 200 and 201 connected to the battery units. 10-13, which is a control method used for acquiring a contractor identification information for identifying a contractor (for example, steps S11 and S61), and a construction acquired in the contractor identification information acquisition step. An authentication step (for example, steps S12 and S62) for authenticating the person identification information, and a control step for performing control related to input / output of current by the power conditioner for the storage battery mounted on the battery unit according to the result of authentication by the authentication step ( For example, steps S31, S32, S43, S44, S43a, S53, Including the 54, etc.) and.

  Thereby, since control is performed according to the result of authentication for distinguishing whether or not a contractor that satisfies a predetermined standard has been constructed, it is possible to suppress the use of the storage battery in an inappropriate state.

  (12) A control program according to an aspect of the present invention is a control program for causing an information terminal 400 including a microprocessor and a photographing unit 405 to execute a predetermined authentication setting process. The photographing unit 405 photographs the installer identification information about the installer who performs the construction related to the power storage system 13 including the battery unit 102 to which the storage batteries 109 a to 109 c are attached and the power conditioner 200 connected to the battery unit 102. Successful authentication in the authentication step (for example, step S62), the authentication step (for example, step S62) for authenticating the contractor identification information acquired in the step (for example, step S61), the contractor identification information acquired in the step. In this case, the power conditioner 200 and the battery unit 10 Of including into at least one, and setting step of transmitting the setting information about the input and output of current to the storage battery (e.g., step S63, S64).

  By installing this control program in the information terminal 400 and causing the microprocessor to execute the control program, the battery unit 102 or the power conditioner 200 can operate by reflecting the authentication result. For this reason, for example, it is possible to perform control so as not to allow the use of the storage battery in the battery unit 102 unless the authentication is successful, and as a result, use of the storage battery in an inappropriate state can be suppressed.
