This management device enables early investigation of the cause when a defect occurs in a manufactured product (automobile).

[0003] Japanese Patent Application Laid-Open No. 2022-162314

[0004] Patent Document 1 discloses a technique for ensuring traceability of parts that are assembled into manufactured products within the same factory of a single business.

[0005] The present inventors have studied how to ensure traceability when assembling multiple types of component parts manufactured in different factories, or component parts manufactured in different locations by multiple businesses, at an assembly factory or at the installation site of the manufactured product.

[0006] In particular, the inventors have examined traceability (the ability to track manufacturing information for each major component part) when constructing or operating a storage system (hereinafter also referred to as ESS) that includes a storage block and a housing that houses multiple storage blocks.

[0007] One aspect of the present invention provides a highly flexible traceability management system and method.

[0008] A traceability management system according to one embodiment of the present invention comprises a data relay device that accepts traceability data (serial numbers, lot numbers, etc.) of multiple components input from each of multiple input media (inputters) that are permitted to be accessed, and an information processing device that acquires the traceability data from the data relay device, associates the traceability data with a local system, and stores the location in the local system of a component having specific traceability data in a searchable manner.

[0009] According to the above aspect, it is possible to provide a highly flexible traceability management system. The traceability management according to the above aspect can also be applied to the construction or operation of a power storage system.

FIG. 7 is a diagram illustrating another example of association between upper and lower levels for traceability management.

[0011] First, an outline of the traceability management system according to the embodiment will be described.

[0012] As shown in FIG. 1, the traceability management system 1 includes a data relay device 10 that receives traceability data of a plurality of component parts input from a plurality of input media 30 that are permitted to be accessed.

[0013] The multiple input media 30 may be terminal devices such as personal computers provided in multiple different factories 30a, 30b, and 30c, or provided in multiple businesses 30a, 30b, and 30c in different locations. The terminal devices can be connected to the data relay device 10 via a network. In this embodiment, it is not necessary to install a specific application (software) on the terminal devices for inputting data into the traceability management system 1. A general web browser is installed on the terminal devices in this embodiment.

[0014] The network includes a public communication network, such as the Internet, and a carrier network that realizes wireless communication according to a predetermined mobile communication standard. The network may also include a local area network such as an in-house LAN, or may include a general optical fiber line or a dedicated line.

[0015] The plurality of input media 30 may further include a terminal device 30d that can read code information of components in a factory or a local system and input traceability data to the data relay device 10. The terminal device 30d may be a mobile terminal device such as a smartphone, tablet, or handheld terminal.

[0016] The multiple input media 30 may include an external linkage system such as a remote monitoring system 30e for remotely monitoring the on-site system, and a customer data management system.

[0017] The data relay device 10 has a folder-structured storage unit that allows multiple input media 30 to input and share traceability data for component parts or files describing traceability data for component parts. The storage unit may include a shared folder within the company. The data relay device 10 may be configured with multiple server devices or may be a so-called cloud server.

[0018] The data relay device 10 in this embodiment is constructed by customizing a file sharing service that allows access settings provided on a cloud server. Therefore, unlike an on-premise system, there is no need to periodically update software for traceability management when replacing hardware such as server devices. Some input media 30 may input traceability data directly into the information processing device 20. The data relay device 10 in this embodiment is highly scalable, being able to accept data from new terminal devices simply by granting access.

[0019] In another embodiment not shown, the traceability management system 1 may be constructed as an on-premise system.

[0020] The traceability management system 1 further includes an information processing device 20 that acquires traceability data from the data relay device 10 as an event (for example, at a predetermined time each day). Alternatively, the information processing device 20 may acquire traceability data from the data relay device 10 in response to a request (for example, in response to a request from a network-connected terminal device, not shown). The information processing device 20 may be configured with one or more server devices. The data relay device 10 described above may be integrated with the information processing device 20.

[0021] The information processing device 20 may perform data processing (batch processing) on ​​the traceability data of the component parts, such as checking for data duplication, checking for missing data, and adding information (e.g., item codes). The information processing device 20 has a data processing function, which can reduce the burden of inputting data onto the input medium 30.

[0022] The information processing device 20 processes the data and stores the traceability data, which is associated with the item code and has a defined hierarchical relationship, for each on-site system. The on-site system may be a fixed system.

[0023] Traceability management using such a traceability management system 1 can be applied to the construction or operation of an ESS. When a failure or malfunction occurs in an ESS and the component that caused it is identified, the extent of the impact of other components that have the same traceability data can be determined. The impact is not limited to the impact within the same ESS, but can also be determined across multiple ESSs.

[0024] The information processing device 20 of the traceability management system 1 stores traceability data so that the location or position of a component part having specific traceability data in the on-site system can be searched and specified.

[0025] In an ESS that contains many components with the same appearance (containers, panels, storage blocks, etc.), it is extremely useful to be able to search and identify the location in the ESS of components with specific traceability data. This function improves the efficiency of ESS maintenance, enables stable system operation, and enables preventive maintenance.

[0026] In order to explain such technical effects, an overview of the ESS and the hierarchical structure for traceability management in the ESS will be explained.

[0027] The introduction of ESSs is expanding to expand the use of renewable energy, promote energy management, and facilitate power interchange and distribution. ESSs are often operated for long periods of time, such as 15 or 20 years. This has led to a growing need for remote monitoring services that monitor the status of ESS components, as well as maintenance services that provide regular inspections, part replacement, and troubleshooting during the operation period.

[0028] By applying traceability management, it becomes possible to provide ESS remote monitoring services and maintenance services stably with high reliability. It is desirable to ensure traceability not only for the components at the time of ESS construction (new installation), but also for replacement parts during the operation period of 10 years or more. ESS is typically constructed as follows:

[0029] As shown in Fig. 2, the battery panel 40 has a metal panel 41 (a type of housing), and a plurality of power storage modules 43 (a type of power storage block) are housed in the panel 41. The plurality of power storage modules 43 form a plurality of groups (banks). The panel 41 shown in Fig. 2 houses three banks, each made up of two vertical rows of power storage modules 43.

[0030] 2 , each bank is configured by electrically connecting in series two vertical columns of a total of 18 power storage modules 43. The number of power storage modules 43 constituting each bank can be selected arbitrarily. For example, a bank may be configured by one and a half vertical columns of power storage modules 43 or one vertical column of power storage modules 43.

[0031] The battery panel 40 can be provided as a product with different voltage ranges by changing the number of storage modules 43 that make up each bank. For example, as shown in Figure 2, a 1200V battery panel 40 can be provided by connecting two vertical rows of storage modules 43 in series to form one bank.

[0032] Although not shown, by reducing the number of storage modules 43 that make up a bank, it is possible to provide products for different voltage ranges, such as 600 V, 750 V, and 900 V. The external appearance is almost the same, and storage battery panels 40 for these different voltage ranges are associated with different item codes (information indicating what the component is).

[0033] A protection unit 100 (also referred to as a BPU (Battery Protection Unit) in FIG. 5) is disposed above each bank. In the example of FIG. 2 in which three banks are accommodated on the board 41, three protection units 100 are disposed side by side in the horizontal direction within the board 41. Alternatively, a protection unit 100 may be disposed below each bank.

[0034] The battery panel 40 is assembled in a factory, and the traceability data of the battery panel 40 (such as a serial number and a manufacturing number including a subnumber) is stored in the information processing device 20 (see FIG. 1).

[0035] The traceability data of the container 3 (a type of housing) shown in Fig. 2 is stored in the information processing device 20 at the same factory as the battery panel 40, at a different factory, or at the installation site of the ESS. The ESS can be constructed by an on-site assembly method or a factory completion method (manufacturer completion method).

[0036] In the case of the on-site assembly method, multiple battery panels 40 are housed in a container 3 (or a power storage room in a building) at the installation site of the ESS, and the ESS is constructed together with a power conditioner (PCS) (not shown). In this specification, the meaning of ESS also includes the battery equipment (battery storage system, center of Figure 2) excluding the power conditioner.

[0037] In this embodiment, nine battery panels 40 and one control panel 48 are housed in the container 3. Therefore, the traceability data of the nine battery panels 40 and the traceability data of one control panel 48 are associated with the traceability data of the container 3. The same applies to the case of a manufacturer-completed system in which storage in the container 3 is performed in a factory. As will be described later, if the battery panel 40 has waterproof and dustproof properties that allow it to be installed outdoors, the container 3 may be omitted.

[0038] In the example of Fig. 2, 54 energy storage modules and three protection units 100 are housed in one panel 41, so the container 3 includes 486 (= 54 x 9) energy storage modules 43 and 27 (= 3 x 9) protection units 100. In many cases, an ESS is not made up of one container 3, but of multiple containers 3 (right side of Fig. 2). In this way, in an ESS, a large number of components with the same appearance (containers 3, panels 41, energy storage modules 43, protection units 100, etc.) are arranged closely together.

[0039] The constructed ESS is associated with local system identification information (e.g., customer identification information) via the terminal device 30d. For example, with the terminal device 30d selecting specific local system identification information, the terminal device 30d reads code information (e.g., barcode information or two-dimensional code information) attached to the container 3, and associates the traceability data of the container 3 with the local system identification information. If the ESS includes multiple containers 3, the multiple containers 3 are associated with the local system identification information.

[0040] In this way, the traceability data of the container 3 is associated with the traceability data of the battery panel 40 and control panel 48 housed in the container 3 according to the hierarchical relationship of the ESS (see FIG. 5), i.e., local system identification information-container-battery panel, and local system identification information-container-control panel. This association of components according to the hierarchical relationship of the ESS is highly versatile. Using the same concept, traceability management can be performed for ESSs of multiple different voltage ranges.

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

[0042] 3 shows the electrical configuration inside the container 3. A plurality of power storage modules 43 (power storage blocks) are connected in series to form a bank. A protection unit 100 is provided on the power line (main circuit line) of each bank. The protection unit 100 has a switch and protects the power storage modules 43 of the bank from overcharging and overcurrent.

[0043] Management units 105 and 106 (also referred to as BMU: Battery Management Unit in FIG. 5) are provided for each bank and for a group (hereinafter referred to as a domain) in which a plurality of banks are connected in parallel.

[0044] The power storage module 43 has a module (shown at the bottom left of FIG. 5 , also called a battery pack) configured by connecting a plurality of power storage cells (lithium ion secondary batteries in this embodiment) in series and / or parallel. The power storage cells may be prismatic cells, cylindrical cells, or laminated cells (pouch cells).

[0045] The management unit 105 provided in each bank communicates with the monitoring board 44 (also referred to as a CMU (Cell Management Unit) in FIG. 5 ) provided in each power storage module 43 in the bank via a communication line 119. The management unit 105 acquires status data of the power storage module 43 and the power storage cells (measurement data such as cell voltage and temperature).

[0046] As will be described later, the modules and the monitoring boards 44 of the power storage modules 43 can be replaced separately. In the ESS, the number of modules and monitoring boards 44 is very large (in the example of FIG. 2, one container 3 has 486 of each), and there is a relatively high possibility that partial replacement will be required during operation.

[0047] The management unit 106 provided in the domain can communicate with the management unit 105 of each bank via the communication bus 120, and collects status data of the power storage modules 43 and power storage cells acquired by the management unit 105.

[0048] A communication device 107 is connected to the management unit 106 of the domain. The communication device 107 transmits status data acquired from each management unit 105 via the management unit 106 to, for example, 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 a control panel 48 (see FIG. 2).

[0049] 4, the support member 101 of the protection unit 100 has a front panel 101a and a bottom panel 101b. The bottom panel 101b supports a bank management unit 105, an electromagnetic contactor (also referred to as an MC (Magnet Contactor) in FIG. 5) as a switch (not shown), and other components.

[0050] As shown in FIG. 5 , in this embodiment, the traceability data of each battery panel 40 housed in the container 3 is associated with the traceability data of the 54 storage modules 43, the traceability data of the three protection units 100, and the traceability data of the other components.

[0051] The traceability data of each power storage module 43 is associated with the traceability data of one module and the traceability data of one monitoring board 44 .

[0052] The traceability data of each protection unit 100 is associated with the traceability data of one management unit 105, the traceability data of the electromagnetic contactor MC, and the traceability data of other components (such as fuses) not shown.

[0053] In this way, the traceability data is associated along the hierarchical relationship of the battery panel 40, that is, battery panel - power storage module - module and monitoring board, and battery panel - protection unit - management unit and electromagnetic contactor.

[0054] Furthermore, the traceability data of the control panel 48 is associated with the traceability data of the management unit 106 of the domain and the traceability data of other parts.

[0055] In addition to the hierarchical relationships among the battery panels 40 described above, bank identification information (hereinafter referred to as a total bank number) that spans multiple battery panels 40 (for example, across the entire ESS) is assigned to the banks within each battery panel 40. The necessity for a total bank number and an example of a method for assigning the number will be described below.

[0056] 2, three banks are housed in panel 41. By assigning identification information such as A, B, and C to these banks at the factory where battery panel 40 is manufactured, it is possible to identify whether a particular bank is on the left (A), center (B), or right (C) side of panel 41. In other words, the traceability data for a bank is made up of a set of an item code indicating that the battery panel 40 includes three banks, the serial number of battery panel 40, and one of the identification information A to C.

[0057] Similarly, if six banks are stored in panel 41, the banks can be assigned codes A to F, thereby identifying which bank in panel 41 a particular bank belongs to. In other words, the traceability data for a bank is made up of a set of an item code indicating that the battery panel 40 includes six banks, the serial number of the battery panel 40, and any one of the identification information A to F.

[0058] However, because a container 3 houses multiple battery panels 40 (nine in the example of FIG. 2 ), simply assigning the codes A to C to each of the three banks makes it impossible to identify the location of a particular bank within the container 3. This is because it is unknown how the nine battery panels 40 will be laid out within the container 3. Even when a large number of battery panels 40 are housed in a storage room of a building instead of the container 3, simply assigning the codes A to C to each of the three banks makes it impossible to identify the location of a particular bank within the storage room.

[0059] Therefore, in addition to the bank identification information (A to C, etc.) for each battery panel 40, a total bank number spanning multiple battery panels 40 must be assigned to the banks within each battery panel 40.

[0060] International Patent Application PCT / JP2022 / 032030 (the contents of which relating to bank number assignment are incorporated herein by reference) filed by the same applicant as the present patent application discloses, as related technology, a technology for reproducing the bank layout of an on-site ESS on a web screen provided by a remote monitoring system. When constructing an ESS, identification data is sequentially transmitted from a host device, and the switches of multiple bank management units, each of which has a switch, are sequentially operated to store the identification data in each bank management unit. This assigns a total bank number to each bank management unit.

[0061] The traceability management system 1 of this embodiment shown in FIG. 1 has a data linking function with a remote monitoring system 30e.

[0062] When constructing the ESS, the traceability management system 1 may provide the traceability data of all the battery panels 40 shown in FIG. 2 (including the traceability data of all the power storage modules 43) to the remote monitoring system 30e.

[0063] The traceability management system 1 acquires the total bank number data from the remote monitoring system 30e, which knows the total bank number of each bank management unit using the technology of the above-mentioned international patent application. The information processing device 20 acquires the total bank number data associated with the traceability data of each battery panel 40 from the remote monitoring system 30e.

[0064] When the ESS is constructed by the on-site assembly method, the information processing device 20 may acquire the total bank number that is sequentially assigned to each bank management unit by the technology of the above-mentioned international patent application.

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

[0066] The web screen 330 includes a menu 331 with options such as "System Search," "Lifespan Prediction," "Download," and "Report." When "System Search" is selected from the menu 331, a page is displayed that includes a list of link information to systems to which the user logged in to the remote monitoring server has access rights. The web screen 330 also includes a button 332 for logging out or exiting the operation.

[0067] When a system is selected from the link information list in FIG. 6A, the screen transitions to the web screen in FIG. 6B. In FIG. 6B, two power conditioners (PCS) and multiple banks included in the domain are displayed in accordance with the ESS configuration in the "XY City Mega Solar System." Icons 333 indicating "+" or "-" for expanding or collapsing the hierarchical structure of the banks and modules, icons 334 for displaying detailed information, links 335 to network interface cards, and the like are displayed on the screen. A menu icon 338 for the selected system is also included on the screen.

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

[0069] In FIG. 1 , only one bank of the multiple banks included in the "battery panel 1" in the "container 2" is shown, namely, "storage module 1, storage module 2, storage module 3, ...", but in reality, the "battery panel 1" includes three banks. By operating the "+" or "-" icon 21 on the web screen, the storage modules of those banks can be displayed.

[0070] Furthermore, the information processing device 20 stores searchable information about the location (physical location) of a housing in the ESS in which a component having specific traceability data is installed.

[0071] For example, suppose a problem occurs in the monitoring board "CMU" of the "storage module 3" of the "storage battery panel 1" included in the "container 2" in the "ESS 1" shown in FIG. 1 . For example, the serial number of the monitoring board "CMU" of the "storage module 3" is entered into a search box prepared on a web screen by the information processing device 20. This makes it possible to instantly search for which storage modules in the container 2 the monitoring board "CMU" with the same traceability data is used, whether it is also used in the neighboring "container 1," or whether it is also used in the "ESS 2" located elsewhere. The information processing device 20 transmits screen information of the web screen displaying the search results to the client device.

[0072] Instead of the web screen provided by the information processing device 20, the traceability data of the ESS components can also be checked on the web screen provided by the remote monitoring system shown in FIG.

[0073] Furthermore, replacement parts can also be identified on a web screen provided by the information processing device 20.

[0074] If a malfunction occurs in the monitoring board of the "power storage module 3" and a maintenance technician replaces the monitoring board with a new monitoring board on-site, the old monitoring board "CMU" is displayed with a strikethrough or grayed out, as shown in FIG. 1 . The new monitoring board "CMU new" is then displayed adjacent to the old monitoring board. This allows the user to intuitively understand which component has been replaced with which component on the web screen provided by the information processing device 20. The "CMU" and "CMU new" used here are examples of notation for explanation purposes, and in reality, alphabets and numbers may be used instead.

[0075] In order to identify the replacement part, the maintenance staff reads the code information of the monitoring board "CMU" that was removed on-site using the terminal device 30d, associates it with the traceability data of the "power storage module 3", and inputs it into the data relay device 10. Similarly, the maintenance staff reads the code information of the new monitoring board "CMU new" using the terminal device 30d, associates it with the traceability data of the "power storage module 3", and inputs it into the data relay device 10.

[0076] When replacing the entire storage module instead of replacing only the monitoring board "CMU", the maintenance worker reads the code information of the old and new storage modules using the terminal device 30d, associates it with the traceability data of the "storage battery panel 1", and inputs it into the data relay device 10.

[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 data can be checked on a web screen provided by the remote monitoring system.

[0078] The present invention is not limited to the above-described embodiment. In the case of an ESS in which multiple battery panels 40 and a power conditioner (PCS) are installed outdoors without a container, a higher-level and lower-level correspondence for traceability management, as shown in FIG. 7, may be adopted. Specifically, traceability data is associated along the lines of local system identification information—multiple battery panels 40, and local system identification information—PCS panel. The local system identification information may include layout information such as a total bank number. Traceability data for multiple conversion units included in the power conditioner and traceability data for other components (such as control units) are associated with the traceability data of the PCS panel. Traceability management using the traceability management system 1 may also be applied to systems other than ESSs. For example, similar to ESSs, the system may be applied to systems (such as power supply systems) that operate for periods of 10 years or more, systems that are remotely monitored, and systems that require component replacement. The data relay device 10 may be a portable storage medium. However, from the viewpoint of data exchange efficiency, the data relay device 10 shown in FIG. 1, which exchanges data via a network, is preferable.

[0079] Instead of the power storage module 43, for example, long power storage cells extending from the front surface to the back surface of the panel 41 (housing) may be housed in the panel 41. A bank may be formed by connecting a plurality of long power storage cells in series.

[0080] As the switch, a molded case circuit breaker (MCCB) may be used instead of an electromagnetic contactor (MC) that opens and closes in response to a signal from the management unit 105 .

[0081] The following provides a summary of the embodiments and their technical effects.

[0082] (1) The traceability management system 1 comprises a data relay device 10 that accepts traceability data of a plurality of component parts input from each of a plurality of input media 30 that are permitted to be accessed, and an information processing device 20 that acquires the traceability data from the data relay device 10, associates the traceability data with a local system, and stores the location in the local system of a component part having specific traceability data so that it can be searched for.

[0083] According to the above configuration, the data relay device 10 can be used to aggregate traceability data when multiple types of components manufactured in different factories or components manufactured at different locations by multiple businesses are assembled at an assembly factory or at the installation site of the manufactured product. There is no need to install a specific application on the terminal device to input data into the traceability management system 1. The data relay device 10 can be configured by customizing a file sharing service with access settings provided on a cloud server and / or by using an in-house shared folder. According to the above configuration, a highly flexible traceability system 1 can be provided with a small initial investment.

[0084] (2) In the traceability management system 1 described above in (1), the on-site system may be an ESS including a plurality of housings 41 (or 3) that house a plurality of storage blocks 43 (or 40), and the information processing device 20 may store information in a searchable manner as to which housing 41 (or 3) in the ESS a component having the specific traceability data is located and in which position (so that the position in the ESS can be searched and identified on a screen based on screen information such as web screen information provided by the information processing device 20).

[0085] The above configuration provides a traceability system 1 suitable for constructing or operating an ESS. An ESS has a large number of components (e.g., containers 3, panels 41, energy storage modules 43, and protection units 100) with similar appearances densely arranged, like trees densely packed in a forest. Being able to search for and identify the location of components with specific traceability data in the ESS dramatically improves maintenance efficiency. An ESS is required to avoid system shutdowns as much as possible and to restore the system as quickly as possible if it does shut down, for various purposes such as stabilizing grid power, efficiently utilizing power through energy management, and seizing opportunities for power distribution. The traceability management system 1 of this embodiment enables stable system operation and preventive maintenance, thereby improving the reliability of ESS operation.

[0086] (3) The traceability management system 1 described in (2) above may have a data linking function with a remote monitoring system 30e that monitors the status of the ESS.

[0087] The above configuration satisfies the needs for maintenance services that include periodic inspections, part replacement, and troubleshooting during the ESS operation period. This enables advanced preventive maintenance, rapid recovery from problems, and operational stability that cannot be achieved by the remote monitoring system 30e alone.

[0088] (4) In the traceability management system 1 described above in (3), the information processing device 20 may acquire bank identification information for each of the multiple banks included in the ESS from the remote monitoring system 30e.

[0089] The above configuration enables more efficient maintenance, reduced burden on maintenance personnel, and rapid recovery from problems to a level that cannot be achieved by the traceability management system 1 alone. In an ESS, there are a large number of modules and monitoring boards 44, and the possibility that partial replacement will be required during operation is relatively high. By obtaining bank identification information from the remote monitoring system 30e, maintenance personnel can easily identify the module, monitoring board 44, or power storage module 43 that needs to be replaced.

[0090] (5) In the traceability management system 1 described above in (2) or (3), the information processing device 20 may store the traceability data of the component parts before replacement and the traceability data of the component parts after replacement in the ESS in a manner that allows them to be distinguished.

[0091] The above configuration makes it easy to determine which components in the ESS have been replaced. An ESS is expected to be operated for long periods, such as 15 or 20 years, during which time personnel and technology changes are expected. Examples of technology changes include changes in the specifications of the integrated circuits (ICs) mounted on the monitoring board 44 (CMU), even if the circuit configuration remains the same, and changes in the software version executed by the microcomputer (CPU). The above configuration makes it easy to track and determine which versions of components were used until when and which versions were used afterward during the long operation period of the ESS, even if the person managing or maintaining the ESS changes. This allows for quick investigation of the cause of ESS operation problems. It also enables the provision of advanced maintenance services. In cooperation with the remote monitoring system 30e, services such as storing the history of replaced parts and providing reports can also be provided.

[0092] (6) In the traceability management system 1 described in (2) or (3) above, the traceability data of the components may be associated with each other along the hierarchical relationship of the ESS, including the relationship between the container 3 and the battery panel 40. (7) In the traceability management system 1 described in (2), (3) or (6) above, the traceability data of the components may be associated with each other along the hierarchical relationship of the ESS, including the relationship between the battery panel 40 and the storage block 43.

[0093] According to the above configuration, traceability management of ESSs in a plurality of different voltage bands can be performed using the same concept.

[0094] (8) The traceability management method includes receiving traceability data of multiple components of a power storage system including multiple housings that house multiple power storage blocks, which is input from each of multiple input media 30 that are permitted to be accessed, using a data relay device 10, acquiring the traceability data from the data relay device 10, associating the traceability data with the power storage system, and storing the traceability data in an information processing device 20 so that the location in the power storage system of a component having specific traceability data can be searched for.

[0095] According to the above configuration, traceability data of multiple components of the ESS can be received with high flexibility using the data relay device 10. This enables stable operation and preventive maintenance of the system, thereby improving the reliability of ESS operation.

[0096] (9) The traceability management method of (8) above may further include, when replacing the storage block or a component of the storage block, reading traceability data of the component before replacement and the component after replacement by a terminal device and transmitting the data to the data relay device.

[0097] According to the above configuration, when replacing power storage blocks or their components, which are extremely numerous in an ESS and are relatively likely to require partial replacement during operation, traceability data can be stably collected in a predetermined procedure and stored in an information processing device, making it possible to provide services such as storing the history of replaced parts and providing reports.
