[0004] Patent Document 1 describes a technology for ensuring the traceability of parts assembled into a product in the same factory of a company.

[0005] The present inventors have investigated ensuring traceability in the assembly of a plurality of component types from different plants or of components manufactured by a plurality of companies at different locations in an assembly plant or at an installation site of a manufactured product.

[0006] In particular, the inventors investigated traceability (traceability of manufacturing information for each main component) in a case of constructing or operating an energy storage system (hereinafter also referred to as ESS) that includes an energy storage block and a casing that accommodates a plurality of energy storage blocks.

Fig. Figure 7 is a diagram illustrating another example of the connection between higher order and lower order for traceability management. Mode for carrying out the invention

[0010] First, a traceability management system according to an embodiment will be described.

[0011] As in the Fig. 1, a traceability management system 1 includes a data forwarding device 10 that receives traceability data of a plurality of components input by each of the plurality of authorized inputters 30.

[0012] The input devices 30 may be terminal devices such as personal computers provided in a plurality of different factories 30a, 30b, and 30c, or provided in a plurality of enterprises 30a, 30b, and 30c at different locations. The terminal device is communicatively connected to the data forwarding device 10 via a network. In the present embodiment, it is not necessary to install a special application (software) on the terminal device to input data into the traceability management system 1. A general web browser is installed on the terminal device according to the present embodiment.

[0013] The network comprises a public communications network, the so-called Internet, and a carrier network that implements wireless communication according to a predefined mobile radio standard. The network can comprise a local area network, such as an internal LAN, or be a general-purpose optical line or a leased line.

[0014] The plurality of input devices 30 may further include a terminal device 30d capable of reading code information of a component in a factory or local system and inputting the traceability data into the data forwarding device 10. The terminal device 30d may be a mobile device such as a smartphone, a tablet, or a cell phone.

[0015] The plurality of inputs 30 may include an external cooperation system, such as a remote monitoring system 30e for remotely monitoring the local system, and a customer data management system.

[0016] The data forwarding device 10 includes a storage unit with a folder configuration in which the plurality of authorized inputters 30 can input and share the component traceability data or a file describing the component traceability data. The storage unit may include an internal shared folder. The data forwarding device 10 may be structured by a plurality of server devices or may be a so-called cloud server.

[0017] The data forwarding device 10 according to the present embodiment is constructed by customizing a file sharing service provided on the cloud server, where access settings can be configured. Therefore, unlike a local system, it is not necessary to regularly update the software when hardware such as a server device for traceability management is replaced. Some inputters 30 can directly input the traceability data into an information processing device 20. The data forwarding device 10 in the present embodiment can accept data from a new terminal device only by granting access and has excellent expandability.

[0018] As a further embodiment not shown, the traceability management system 1 can be set up as a local system.

[0019] The traceability management system 1 further includes the information processing device 20, which obtains the traceability data from the data forwarding device 10 in an event-driven manner (e.g., at a set time of day). Alternatively, the information processing device 20 may obtain the traceability data from the data forwarding device 10 in response to a request (e.g., in response to a request from a terminal device (not shown) connected to a network). The information processing device 20 may be constructed from one or a plurality of server devices. The data forwarding device 10 described above may be integrated into the information processing device 20.

[0020] The information processing device 20 can perform data processing (batch processing), such as checking for data overlaps, checking for missing data, and adding information (e.g., an item number) to the component's traceability data. Since the information processing device 20 has a data processing function, it is possible to reduce the input workload of the inputter 30.

[0021] Through data processing, the information processing device 20 stores the traceability data associated with the article number with a hierarchy defined for each local system. The local system can be a stationary system.

[0022] Traceability management using such a traceability management system 1 can be used during the construction or operation of an ESS. If a fault or defect occurs in a specific ESS and the component causing the fault is identified, it is possible to capture the distribution area of ​​a component using the same traceability data. This allows not only the distribution area within the same ESS, but also the distribution area across multiple ESSs to be captured.

[0023] The information processing device 20 of the traceability management system 1 stores the traceability data such that the location (site or position) of a component with specific traceability data can be searched and designated in the local system.

[0024] In an ESS with a large number of components (containers, cabinets, energy storage blocks, etc.) with the same appearance, it is very helpful to be able to search for and identify the location of the component with specific traceability data in the ESS. This function improves the maintenance efficiency of the ESS and enables stable operation and preventive maintenance of the system.

[0025] To describe this technical effect, an overview of the ESS and the hierarchy (hierarchical structure) for traceability management in the ESS are described.

[0026] ESS is increasingly being implemented to expand the use of renewable energy, promote energy management, and improve power exchange and distribution. ESS is often operated over a long period of 15 to 20 years. Therefore, there is a growing need for a remote monitoring service to monitor the condition of ESS components and a maintenance service to conduct regular inspections, parts replacement, and troubleshooting during operation.

[0027] By implementing traceability management, it is possible to provide stable and highly reliable remote monitoring and maintenance services for the ESS. In addition to the components at the time of ESS construction (new installation), it is also desirable to ensure the traceability of replacement parts during the operating period of more than 10 years. The typical structure of an ESS is as follows:

[0028] As in the Fig. 2, a storage battery cabinet 40 comprises a metal cabinet 41 (a type of housing) in which a plurality of energy storage modules 43 (a type of energy storage blocks) are accommodated. The plurality of energy storage modules 43 form a plurality of groups (banks). Fig. The cabinet 41 shown in Figure 2 accommodates three banks, each with two rows of energy storage modules 43 in the vertical direction.

[0029] In the example of Fig. 2, each bank comprises a total of eighteen energy storage modules 43, which are electrically connected in series in two rows in the longitudinal direction. The number of energy storage modules 43 forming each bank can be freely selected. For example, the bank can comprise one and a half rows of energy storage modules 43 in the vertical direction or one row of energy storage modules 43 in the vertical direction.

[0030] The storage battery cabinet 40 is provided as a product in a different voltage range by varying the number of energy storage modules 43 forming each bank. As shown in the Fig. 2, for example, a 1200 V battery storage cabinet 40 is provided by connecting two rows of energy storage modules 43 in series in the vertical direction to form a battery bank.

[0031] Although not shown, products in different voltage ranges such as 600 V, 750 V, and 900 V can be provided by reducing the number of energy storage modules 43 constituting the bank. The battery storage cabinets 40 in these different voltage ranges, with substantially the same appearance, are assigned different article numbers (information indicating which component they are).

[0032] Above each bank is a protection unit 100 (in the Fig. 5 also called battery protection unit (BPU). In the example of the Fig. 2, in which three banks are accommodated in the cabinet 41, three protection units 100 are arranged side by side in a lateral direction in the cabinet 41. Alternatively, the protection unit 100 can also be arranged below each bank.

[0033] The storage battery cabinet 40 is assembled in a specific factory and the traceability data (serial number, production number including branch number, etc.) of the storage battery cabinet 40 are stored in the information processing device 20 (see the Fig. 1).

[0034] The traceability data of a Fig. The components of the container 3 (a type of housing) shown in Figure 2 are stored in the information processing device 20 in the same factory as the storage battery cabinet 40, in another factory, or at the installation site of the ESS. The manufacturing processes of the ESS include a local assembly process and a factory completion process (manufacturer completion process).

[0035] In the case of the local assembly method, a plurality of storage battery cabinets 40 are accommodated in the container 3 (or an energy storage room of a building) at the installation site of the ESS, and the ESS is manufactured together with a voltage regulator (PCS) not shown. In this description, the battery storage facility (a battery storage system in the middle of the Fig. 2) without the voltage regulator as defined by the ESS.

[0036] In the present embodiment, nine storage battery cabinets 40 and one control cabinet 48 are housed in the container 3. Therefore, the traceability data of the nine storage battery cabinets 40 and the traceability data of the control cabinet 48 are associated with the traceability data of the container 3. The same applies to the case where the manufacturer's completion process in which the recording in the container 3 is carried out in a factory.

[0037] As described later, the container 3 can be omitted if the storage battery cabinet 40 is waterproof and dustproof and allows outdoor installation.

[0038] In the example of Fig. 2, forty-five energy storage modules and three protection units 100 are housed in a cabinet 41, so that the container 3 contains four hundred sixty-eight (= 54 × 9) energy storage modules 43 and twenty-seven (= 3 × 9) protection units 100. The ESS often comprises a plurality of containers 3 instead of one container 3 (right in the Fig. 2). As a result, a large number of components (containers 3, cabinets 41, energy storage modules 43, protection units 100, etc.) with the same appearance are densely arranged in the ESS.

[0039] The created ESS is associated with local system identification information (e.g., customer identification information) via the terminal 30d. For example, the terminal 30d reads the code information (e.g., barcode information or two-dimensional code information) attached to the container 3 in a state where the specific local system identification information has been selected, and the traceability data of the container 3 is associated with the local system identification information. In a case where the ESS includes a plurality of containers 3, the plurality of containers 3 are associated with this local system identification information.

[0040] In this way, the traceability data of container 3 are associated with the traceability data of the storage battery cabinet 40 and the control cabinet 48 located in container 3 along the ESS hierarchy (see the Fig. 5), i.e., the local system identification information - the container - the storage battery cabinet and the local system identification information - the container - the control cabinet. The assignment of components along the ESS hierarchy is extremely flexible. Using the same concept, the traceability management of the ESS can be implemented across a variety of different voltage ranges.

[0041] Next, the configuration of the storage battery cabinet 40 and the hierarchy (hierarchical structure) for traceability management in the storage battery cabinet 40 will be described.

[0042] The Fig. Figure 3 shows the electrical configuration in the container 3. The plurality of energy storage modules 43 (energy storage blocks) are connected in series to form the bank. The protection unit 100 is provided on a power line (main power line) of each bank. The protection unit 100 includes a switch for protecting the energy storage module 43 of the bank from overcharging and overcurrent.

[0043] In each bank and in a group obtained by connecting a plurality of banks in parallel (hereinafter referred to as domain), there are respectively management units 105 and 106 (in the Fig. 5 also referred to as Battery Management Units (BMUs).

[0044] The energy storage module 43 comprises a module (bottom left in the Fig. 5, also referred to as a composite battery), which is formed by connecting a plurality of power storage cells (in the present embodiment, a lithium-ion secondary battery) in series and / or parallel. The power storage cell may be a prismatic cell, a cylindrical cell, or a laminate cell (pocket cell).

[0045] The management unit 105 provided in each bank communicates via a communication line 119 with a monitoring cabinet 44 (in the Fig. 5, also referred to as a cell management unit (CMU), which is included in each energy storage module 43 in the bank. The management unit 105 obtains status data (measurement data such as cell voltage and temperature) of the energy storage module 43 and the power storage cell.

[0046] As will be described later, the module and the monitoring cabinet 44 of the energy storage module 43 can be replaced separately. In the ESS, the number of modules and the number of monitoring cabinets 44 are very large (in the example of Fig. 2 four hundred eighty-six for one container 3) and the probability of partial replacement during operation is relatively high.

[0047] The management unit 106 provided in the domain can communicate with the management unit 105 of each bank via a communication bus 120 and aggregates the status data of the energy storage module 43 and the power storage cell obtained from the management unit 105.

[0048] A communication device 107 is connected to the domain management unit 106. The communication device 107 transmits the status data obtained from each management unit 105 via the management unit 106, for example, to a remote monitoring system (remote monitoring server) not shown. The communication device 107 may be a network card-type communication device (network interface card). The management unit 106 and the communication device 107 are housed in the control cabinet 48 (see the Fig. 2).

[0049] As in the Fig. 4, a support element 101 of the protection unit 100 comprises a front surface element 101a and a bottom surface element 101b. The bank's management unit 105, an electromagnetic contactor not shown as a switch (in the Fig. 5 also referred to as magnetic contactor (MC)) and other parts are mounted on the bottom surface element 101b.

[0050] As in the Fig. 5, in the present embodiment, the traceability data of fifty-four energy storage modules 43, the traceability data of three protection units 100, and the traceability data of other parts are associated with the traceability data of each storage battery cabinet 40 accommodated in the container 3.

[0051] The traceability data of a module and the traceability data of a monitoring cabinet 44 are associated with the traceability data of each energy storage module 43.

[0052] The traceability data of a management unit 105, the traceability data of the electromagnetic contactor MC, and the traceability data of other parts (e.g., fuses) not shown are associated with the traceability data of each protection unit 100.

[0053] In this way, the traceability data is assigned along the hierarchy of the storage battery cabinet 40, i.e., the storage battery cabinet - the energy storage module - the module - the monitoring cabinet and the storage battery cabinet - the protection unit - the management unit - the electromagnetic contactor.

[0054] The traceability data of the domain management unit 106 and the traceability data of other parts are associated with the traceability data of the control cabinet 48.

[0055] In addition to the hierarchy in the storage battery cabinet 40 described above, bank identification information (hereinafter referred to as a collective bank number) is assigned to the bank in each storage battery cabinet 40 across a plurality of storage battery cabinets 40 (e.g., an entire ESS). The necessity of the collective bank number and an example of its assignment method are explained below.

[0056] In the example of Fig. 2, three banks are housed in the cabinet 41. For example, by assigning identification information such as A, B, and C to the banks in the factory of the storage battery cabinet 40, it is possible to specify which bank is located on the left side (A), in the middle (B), and on the right side (C) in the cabinet 41. The bank's traceability data is represented by a set of the article number indicating the storage battery cabinet 40 with the three banks, the production number of the storage battery cabinet 40, and the identification information of any one of A to C.

[0057] Even in the case where six banks are housed in the cabinet 41, it is possible to indicate which bank in the cabinet 41 is a particular bank by assigning reference symbols A to F to the banks. That is, the bank traceability data is configured by a set of the article number indicating the storage battery cabinet 40 with six banks, the production number of the storage battery cabinet 40, and the identification information of any one of A to F.

[0058] However, since a large number of (in the example of Fig. 2 nine) storage battery cabinets 40 are housed in the container 3, it is not possible to unambiguously determine the location in the container 3 of a particular bank simply by assigning reference symbols A to C to each of the three banks. This is because it is not known how the nine storage battery cabinets 40 are spatially arranged in the container 3. Even in a case where a large number of storage battery cabinets 40 are housed in the energy storage room of the building instead of the container 3, it is not possible to determine the location in the container 3 of a particular bank simply by assigning reference symbols A to C to each of the three banks.

[0059] Therefore, it is necessary to assign the total bank number across the plurality of storage battery cabinets 40 to each bank in each storage battery cabinet 40, in addition to the bank identification information (A to C, etc.) for each storage battery cabinet 40.

[0060] International patent application PCT / JP2022 / 032030, filed by the same applicant as the present application (the content regarding bank number assignment is incorporated into the present application by reference), discloses, as related technology, a technology for displaying the arrangement of banks in a local energy storage system (ESS) on a web screen provided by the remote monitoring system. When establishing the ESS, identification data is sequentially transmitted from a higher-level device, and switches of a plurality of bank management units, each including a switch, are sequentially operated to store the identification data in each bank management unit. Each bank management unit is assigned the overall bank number accordingly.

[0061] The Fig. The traceability management system 1 of the present embodiment shown in Fig. 1 has a data cooperation function with the remote monitoring system 30e.

[0062] The Traceability Management System 1 may, when creating the ESS, collect the traceability data of all the Fig. 2 (including the traceability data of all energy storage modules 43) to the remote monitoring system 30e.

[0063] The traceability management system 1 obtains the total bank number data from the remote monitoring system 30e, which acquires the total bank number of each bank management unit according to the technology of the above-described international patent application. The information processing device 20 acquires the total bank number data associated with the traceability data of each storage battery cabinet 40 from the remote monitoring system 30e.

[0064] In the case where the ESS is constructed by the local assembly method, the information processing apparatus 20 can acquire the overall bank number sequentially assigned to each bank management unit according to the technology of the above-described international patent application.

[0065] The remote monitoring system 30e has a web server function as described in Japanese Patent No. 6604373 of the same applicant as the present patent application, and transmits screen information of a web screen 330 (a screen displayed on a display unit of a client device connected to a network) as shown in, for example, the Fig. 6(A).

[0066] The web screen 330 contains a menu 331, for example, "System Search," "Lifetime Forecast," "Download," and "Report." When "System Search" is selected from the menu 331, a page is displayed with a list of link information about systems to which a user logged in to the remote monitoring server has access rights. The web screen 330 includes a button 332 for logging out or exiting the process.

[0067] If a particular system is removed from the link information list of the Fig. 6(A) is selected, the screen changes to the web screen of the Fig. 6(B). The Fig. Figure 6(B) shows two voltage regulators (PCS) and a plurality of banks included in the domain according to the configuration of the ESS in "XY City Mega Solar System." An icon 333 indicating "+" or "-" for expanding or collapsing a hierarchical structure of the bank and module, an icon 334 for displaying detailed information, a link 335 to a network interface card, etc., are arranged on the screen. A menu icon 338 for the selected system is displayed on the screen.

[0068] The Fig. The information processing device 20 shown in Figure 1 stores the traceability data for each local system in a tree structure, for example, similar to that shown in the Fig. 6(B). The information processing device 20 may have a web server function and provide a network-connected terminal (client device) with a hierarchical structure (tree structure) on the web screen, the overview of which is shown in the Fig. 1 is shown.

[0069] Although the Fig. While Figure 1 only represents "energy storage module 1, energy storage module 2, energy storage module 3, ..." of one of the plurality of banks contained in the "storage battery cabinet 1" in the "container 2," the "storage battery cabinet 1" actually comprises three banks. The energy storage modules of the banks can be displayed by pressing a "+" or "-" symbol 21 on the web screen.

[0070] The information processing device 20 stores in a searchable manner at which location (physical location) in which housing in the ESS a component with specific traceability data is provided.

[0071] For example, it is assumed that in the monitoring cabinet “CMU” located in the “Energy Storage Module 3” of the “Storage Battery Cabinet 1” in the “Container 2” of the “ESS1” (see the Fig. 1) A defect has occurred. For example, the serial number of the monitoring cabinet "CMU" of the "Energy Storage Module 3" is entered into a search field prepared on the web screen by the information processing device 20. Then, it is possible to immediately search for the energy storage module in Container 2 in which the monitoring cabinet "CMU" with the same traceability data is used, whether it is used for a neighboring "Container 1", whether it is used for the "ESS2" at a different location, etc. The information processing device 20 transmits screen information from the web screen displaying the search result to the client device.

[0072] Instead of the web screen provided by the information processing device 20, the traceability data of the ESS component can be displayed on the screen provided by the Fig. 6 shown remote monitoring system provided web screen.

[0073] In addition, the replacement part can be identified on the web screen provided by the information processing device 20.

[0074] In the event that a defect occurs in the monitoring cabinet of the “Energy Storage Module 3” and maintenance personnel replace the monitoring cabinet on site with a new monitoring cabinet as described in the Fig. 1, the old monitoring cabinet "CMU" is displayed crossed out or grayed out. The new monitoring cabinet "CMU new" is then displayed next to the old monitoring cabinet. This makes it possible to intuitively understand on the web screen provided by the information processing device 20 which component is being replaced by which component. The designations "CMU" and "CMU new" used here serve as an example for the description; in practice, alphabetical and numerical designations can be used.

[0075] To implement the identification of the replacement part, the maintenance personnel reads the code information of the remote monitoring cabinet "CMU" with the terminal device 30d and enters it, along with the traceability data of the "Energy Storage Module 3," into the data forwarding device 10. Similarly, the maintenance personnel reads the code information of a new monitoring cabinet "CMU new" with the terminal device 30d and enters it, along with the traceability data of the "Energy Storage Module 3," into the data forwarding device 10.

[0076] In the case where an entire energy storage module is replaced instead of just the monitoring cabinet “CMU”, the maintenance personnel reads the code information of the old and new energy storage modules with the terminal device 30d and enters it into the data forwarding device 10 in association with the traceability data of the “storage battery cabinet 1”.

[0077] The information processing device 20 may provide the stored traceability data of the new and old components to the remote monitoring system 30e so that the traceability data can be confirmed on a web screen provided by the remote monitoring system.

[0078] The present invention is not limited to the embodiment described above.

[0079] In a case of the ESS in which a plurality of storage battery cabinets 40 and the voltage regulator (PCS) are installed outdoors without providing a container, a parent and a child assignment for traceability management may be established as shown in the Fig. 7. Specifically, the traceability data is associated with the local system identification information of the plurality of storage battery cabinets 40 and the local system identification information of the PCS cabinet. The local system identification information may include arrangement information such as the overall bank number. The traceability data of a plurality of conversion units present in the voltage regulator and the traceability data of other components (control unit, etc.) are associated with the traceability data of the PCS cabinet.

[0080] The traceability management of Traceability Management System 1 can also be applied to systems other than the ESS. Similar to the ESS, for example, it is possible to deploy a system (power supply system, etc.) with a service life of ten years or more, a remotely monitored system, and a system that requires parts replacement.

[0081] The data forwarding device 10 may be a portable storage medium. However, for reasons of efficiency of data transmission / reception, the data forwarding device 10, which performs data transmission / reception via the Fig. 1 shown network is preferable.

[0082] For example, instead of the energy storage module 43, a long power storage cell extending from the front surface to the rear surface of the cabinet 41 (housing) may be housed in the cabinet 41. Several long power storage cells may be connected in series to form a bank.

[0083] Instead of the electromagnetic contactor (MC), a molded case circuit breaker (MCCB) can be used as the switch, which is opened and closed by a signal from the management unit 105.

[0084] A summary of the embodiment and technical effects is described below. (1) A traceability management system 1 includes a data forwarding device 10 that receives traceability data of a plurality of components input by each of a plurality of authorized inputters 30, and an information processing device 20 that obtains the traceability data from the data forwarding device 10 and stores the traceability data in association with a local system such that a location of a component having specific traceability data can be searched for in the local system.

[0085] According to the configuration described above, the data forwarding device 10 can aggregate traceability data when assembling multiple types of components manufactured at different factories or components manufactured by multiple companies at different locations in an assembly factory or at an installation site of a manufactured product. It is not necessary to install a dedicated application on a terminal device to input data into the traceability management system 1. The data forwarding device 10 can be implemented by customizing a data sharing service that allows access settings and is provided on a cloud server and / or by using an internal shared folder.According to the configuration described above, it is possible to provide a highly flexible traceability system with low acquisition costs.

[0086] (2) In the traceability management system 1 described in item (1) above, the local system may be an ESS including a plurality of casings 41 (or 3) accommodating a plurality of energy storage blocks 43 (or 40), and the information processing device 20 may store in a searchable manner at which location in which casing 41 (or 3) in the ESS the component with specific traceability data is present (such that a location in the ESS can be searched and indicated on a screen based on screen information such as web screen information provided by the information processing device 20).

[0087] According to the configuration described above, it is possible to provide a traceability system 1 suitable for the construction and operation of the ESS. Numerous components (containers 3, cabinets 41, energy storage modules 43, protection units 100, etc.) with the same appearance are densely arranged in the ESS, like densely packed trees in a forest. Since the location of the component can be searched and specified with specific traceability data in the ESS, maintenance efficiency is significantly improved. The ESS must avoid stopping the system as much as possible and must restore it as quickly as possible when the system is stopped for various reasons, such as stabilizing system performance, efficient energy utilization through power management, and exploiting power distribution opportunities.With the traceability management system 1 of the present embodiment, stable operation and preventive maintenance of the system can be performed, and the reliability of the ESS operation can be improved.

[0088] (3) The traceability management system 1 referred to in point (2) described above may have a data cooperation function with a remote monitoring system 30e that monitors the status of the ESS.

[0089] According to the configuration described above, it is possible to adequately meet the maintenance requirements of conducting regular inspections, parts replacement, and troubleshooting during ESS operation. It is possible to ensure advanced preventive maintenance, rapid troubleshooting, and operational stability at a level that cannot be achieved by the 30e remote monitoring system alone.

[0090] (4) In the traceability management system 1 described in item (3) above, the information processing device 20 may obtain the bank identification data of each of the plurality of banks included in the ESS from the remote monitoring system 30e.

[0091] With the configuration described above, it is possible to improve maintenance efficiency, reduce the burden on maintenance personnel, and achieve rapid troubleshooting at a level that cannot be achieved by the traceability management system 1 alone. In the ESS, the number of modules and the number of monitoring cabinets 44 are very large, and there is a relatively high probability of partial replacement during operation. By obtaining the bank identification information from the remote monitoring system 30e, maintenance personnel can easily identify the module, monitoring cabinet 44, or energy storage module 43 to be replaced.

[0092] (5) In the traceability management system 1 described in item (2) or item (3) above, the information processing device 20 may identifiably store traceability data of a component before replacement and traceability data of a component after replacement in the ESS.

[0093] Therefore, with the configuration described above, it is easy to understand which component in the ESS is replaced. The ESS is operated for a long period of time, for example, 15 to 20 years, and the person in charge and technology are expected to change during this period. For example, the technology, a specification of an integrated circuit (IC) mounted thereon, a version of the software executed by the microcomputer (CPU), etc., will change even if a circuit configuration of the monitoring cabinet 44 (CMU) remains the same. According to the configuration described above, it is possible to easily track and record which version of the part is used until when and which version is used afterward over a long period of operation of the ESS, even if the person in charge of managing or maintaining the ESS changes. This makes it possible to quickly determine the cause of malfunctions in the ESS operation.Extended maintenance services are possible. In conjunction with the 30e remote monitoring system, it is also possible to store the history of replacement parts, generate reports, and offer similar services.

[0094] (6) In the traceability management system 1 described above in item (2) or item (3), the traceability data of the components may be allocated along the hierarchy of the ESS, including a relationship between a container 3 and a storage battery cabinet 40.

[0095] (7) In the traceability management system 1 described above according to item (2), item (3) or item (6), the traceability data of the components may be allocated along the hierarchy of the ESS, including a relationship between the storage battery cabinet 40 and the energy storage blocks 43.

[0096] According to the configuration described above, the same concept can be used to perform traceability management of the ESS in a variety of different voltage bands.

[0097] (8) A traceability management method receives traceability data of a plurality of components of an energy storage system, including a plurality of enclosures accommodating a plurality of energy storage blocks, input from each of a plurality of inputters 30 whose access is permitted by a data relaying device 10, obtains the traceability data from the data relaying device 10, and stores the traceability data in an information processing device 20 associated with the energy storage system such that a location of a component having specific traceability data can be searched for in the energy storage system.

[0098] According to the configuration described above, the traceability data of a variety of components of the ESS can be received with high flexibility using the data relay device 10. Stable operation and preventive maintenance of the system can be performed, and the reliability of the ESS operation can be improved.

[0099] (9) In the traceability management method (8) described above, when replacing the energy storage blocks or components of the energy storage blocks, the traceability data of the components before the replacement and the components after the replacement can be read by a terminal device and transmitted to the data forwarding device.

[0100] According to the configuration described above, the traceability data can be stably collected through a predetermined method and stored in the information processing device at the time of replacement of the energy storage blocks or their components, the number of which is extremely high in the ESS, and the probability of a necessary partial replacement during operation is relatively high. This enables the provision of services such as storing a history of replacement parts and providing a report.
