Description
Technical Field
[0001] This invention relates to the field of intelligent operation and maintenance and digital management technology for electrochemical energy storage systems, specifically to a method for full life cycle traceability and ledger linkage update of energy storage systems based on module UID. Background Technology
[0002] Electrochemical energy storage systems are expanding rapidly, with the number of energy storage modules often reaching tens of thousands. The lack of a unified, unique identification mechanism and digital ledger management methods has led to the following problems: Traceability chain broken: During the process of battery production, transportation, installation and operation, information such as module number and serial number is often registered manually, which is prone to errors or loss, and it is impossible to trace the source and flow.
[0003] Delayed record updates: After replacing energy storage modules on-site, manual updates to Excel or databases are often missed or delayed, resulting in discrepancies between the system records and actual data.
[0004] Lifetime and safety management are disconnected: the lack of operational data collection based on unique identifiers makes it impossible to achieve module lifetime assessment, anomaly warning, and safety analysis.
[0005] Decommissioning and recycling management is difficult: the inability to trace the historical operating data of the modules makes it difficult to conduct post-decommissioning assessment, recycling and utilization and responsibility division.
[0006] Therefore, there is an urgent need for an automated traceability and ledger linkage update method that uses module UID as the core and runs through the entire life cycle to achieve integrated management of "physical assets and data assets". Summary of the Invention
[0007] The main objective of this invention is to provide a method for tracing and updating the ledger of an energy storage system throughout its entire lifecycle based on module UID, thereby solving the problems mentioned in the background art.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this invention is: a method for full life cycle traceability and ledger linkage update of energy storage systems based on module UID, including the following steps: S1. Add a UID code to the energy storage module and bind it with multi-dimensional data; S2. Construct a cross-subject UID permission matrix; S3. During the power plant entry and operation and maintenance phase, composite UIDs are identified, their permissions are verified, and they are dynamically updated. S4. During the decommissioning phase of energy storage modules, perform permission switching and full lifecycle data collection.
[0009] Furthermore, the UID code includes: a static base code and a dynamic expiration code; The static base code is written to the read-only memory area of the RFID chip built into the module. The mathematical expression of the static base code is: (1); in, For static base code, For enterprise code, For production batch codes, This is the module serial number. For verification code, For string concatenation operators, This indicates that an MD5 encryption operation is being performed. This means taking the first 8 bits; The mathematical expression for generating dynamic status codes based on static base codes is as follows: (2); in, It is a dynamic status code. This is the initial state identifier. This is the initial health value at the factory. This is the manufacturer's initial authorization code. This indicates the SM3 cryptographic hash algorithm; The dynamic status code is written into the RFID chip's readable and writable storage area to form a complete composite UID. The expression for the composite UID is: (3).
[0010] Furthermore, the initial health value upon leaving the factory can be obtained by calculating the health score, as expressed by: (4); in, The measured health score is the initial health value calculated when the energy storage module leaves the factory. , These are the rated capacity and measured capacity of the energy storage module, respectively. , These are the rated internal resistance and the measured internal resistance of the energy storage module, respectively.
[0011] Furthermore, the detailed process of step S2 is as follows: S201. Determine the subject type and authority level; subject types include: battery manufacturers, energy storage power station operators, third-party operation and maintenance organizations, and decommissioned recycling companies; The access levels are divided into four levels from high to low: Level 4, Level 3, Level 2, and Level 1. Among them, battery manufacturers are at Level 4, energy storage power station operators are at Level 3, third-party operation and maintenance organizations are at Level 2, and decommissioned recycling companies are at Level 1. S202. Construct a UID permission matrix based on permission level and data type; data types include: factory data, running data, maintenance data, and decommissioning data, and these data types are respectively labeled as category 1, category 2, category 3, and category 4 data. S203. Configure permission binding and encryption.
[0012] Furthermore, the UID permission matrix is a 4×4 matrix, where the first... Line 1 Column elements Indicates the first Level 1 permission level for the first Operation permissions for class data; the operation permission value can be 0, 1, or 2. When the value is 0, it means no permission; when the value is 1, it means read-only; and when the value is 2, it means read and write.
[0013] Furthermore, in the permission matrix, the values of the elements are related to the permission level and the data type, and the permission level is denoted as... The data type is denoted as The rules for determining the value are as follows: when It is 4. When the numbers are 1, 2, 3, or 4, the element is 2. when It is 3. When the value is 2 or 3, the element takes the value 2; when It is 3. When the value is 1, the element takes the value 1; when It is 2. When the value is 3, the element takes the value of 2; when It is 2. When the value is 1 or 2, the element takes the value 1; when =1, When the digits are 2, 3, or 4, the element takes the value 1. In other cases, the element is 0.
[0014] Furthermore, the detailed process of step S3 is as follows: S301. Perform module entry verification and data synchronization; Power plant workers use handheld terminals with RFID reading capabilities to scan the composite UID of the module; the terminal automatically... Uploaded to the management platform, verified by the platform. The initial authorization code from the manufacturer is used to complete the data entry verification after it is approved. At the same time, the platform pushes accessible factory data to the terminal with readable permissions according to the power station's three-level permission level. S302. Update the dynamic status code according to the operation and maintenance operation, and then update the composite UID; Maintenance operations include module installation, testing, fault repair, and replacement; Updates to dynamic status codes include: Update status identifiers, update health values, and update the vendor's initial authorization code to a timestamp for each maintenance operation; The expression for updating health values is as follows: (5); in, For the updated health value, The health values are as shown before the update. The failure coefficient, , , The corresponding health coefficient is given, and the sum of the health coefficients is 1. Update the dynamic status code based on the updated status and health value: (6); in, This is the updated dynamic status code. This is the updated status identifier for the energy storage module. For the timestamp of the maintenance operation; The management platform sends the updated dynamic status code to the handheld terminal, which writes it into the module chip via RFID and binds the update record with the static basic code, synchronizing it to the management platform database. Each time a dynamic status code is updated, it triggers an automatic update of the ledger on the management platform, generating a new ledger record. The record includes the static base code, operation type, operation time, status change content, and health value change, realizing the linkage update between physical operations and digital ledgers.
[0015] Furthermore, the health coefficient is a dynamic health coefficient, set as follows: Within one year of the energy storage module's use, the health coefficient corresponding to the measured health score is set to 0.8, while the health coefficients corresponding to the health value and fault coefficient before the update are both 0.1. After one year of use, the health value of the energy storage module fluctuates significantly, and the randomness of the measured health score increases. At this time, the health coefficient corresponding to the measured health score is set to 0.4, while the health coefficients corresponding to the health value and fault coefficient before the update are both 0.3.
[0016] Furthermore, the status identifiers and their associated maintenance operations are as follows: The energy storage module is in storage and awaiting installation. The associated operation and maintenance is as follows: the energy storage module has completed the power station storage after authorization verification and is temporarily stored in the power station warehouse. It has not yet been installed in the energy storage cabinet / battery cluster. During installation, the associated maintenance operation is: the module is being shipped from the warehouse and is being installed on-site; Normal operation, associated maintenance operations are as follows: module installation completed, connected to BMS system, in normal charging and discharging operation state; During operation and maintenance, the associated operation and maintenance actions are: if a module has a minor abnormality or it is time for regular maintenance, stop operation for maintenance; Fault lockout, associated maintenance operations are: if a module experiences a serious fault, the system will automatically lock out and prevent operation; The fault repair is pending re-inspection. The associated maintenance operation is: the faulty module has been repaired, but a re-inspection has not yet been conducted to confirm whether it has returned to normal. The associated operation and maintenance procedures for the decommissioning assessment are as follows: the module operates until its design life / capacity decays to the threshold, the power plant submits a decommissioning application, and waits for the recycling company to assess it; The module is locked out of service, and the associated maintenance operation is as follows: the module completes the retirement assessment and is determined to be "prohibited from reuse".
[0017] Furthermore, the detailed process of step S4 is as follows: S401. The power station operator submits an application to decommission the energy storage module, indicating the reason for decommissioning, and associates the static basic code of the module with the decommissioning and recycling company. The management platform switches permissions and grants the decommissioning and recycling company read-only permissions for operation data, fault history, and lifespan data according to the permission matrix, while retaining the power station operator's historical data viewing permissions. S402. Recycling companies scan the static basic code using a handheld terminal. After the management platform verifies the permissions, it automatically collects the core data of the module's entire lifecycle and pushes it to the terminal in encrypted form. The core data of the entire lifecycle includes: static basic code, rated capacity, initial internal resistance, real-time health value, number of charge and discharge cycles, fault history, and service life.
[0018] Beneficial effects: (1) A composite UID containing static and dynamic codes can record the status and operation and maintenance information of the energy storage module, and realize the traceability of the entire life cycle of the energy storage module; (2) The introduction of cross-subject UID permission matrix can facilitate the management of permissions for multiple subjects; (3) The composite UID itself records the operation and maintenance information, and in essence it also undertakes the function of ledger recording. Combined with the subsequent automatic updating of the ledger, it can avoid the error and omission caused by manual recording of the ledger. (4) The dynamic health coefficient can adapt to the changes in health values over different time periods, making the determination of health values more accurate. Attached Figure Description

This is the initial health value at the factory. This is the manufacturer's initial authorization code. This indicates the SM3 cryptographic hash algorithm; In the aforementioned dynamic status codes, the initial factory health value ranges from 000 to 100, calculated based on factory inspection data; the manufacturer's initial authorization code is temporarily valid and used for initial power plant warehousing verification; the initial status identifiers include the following states: production off-line awaiting inspection, factory inspection in progress, factory inspection passed, factory inspection failed, failed inspection awaiting rework, and passed inspection awaiting shipment. Only modules in the "passed inspection awaiting shipment" state contain the manufacturer's initial authorization code and will pass authorization verification upon power plant warehousing; the initial factory health value can be obtained by calculating a health score, expressed as: (3); in, The measured health score is the initial health value calculated when the energy storage module leaves the factory. , These are the rated capacity and measured capacity of the energy storage module, respectively. , These are the rated internal resistance and the measured internal resistance of the energy storage module, respectively.
[0022] Will Write the data to the RFID chip's readable and writable storage area to form a complete composite UID. The expression for the composite UID is: (4).

The calculation basis is written into the ledger notes, completing the triple binding of composite UID with module physical entity and initial data; core data includes: capacity, internal resistance, and charge / discharge efficiency.
[0024] S2. Construct a cross-subject UID permission matrix to resolve the conflict between multi-subject data sharing and security, laying the rule foundation for subsequent end-to-end data interaction. The detailed process is as follows: S201. Determine the subject type and authority level; subject types include: battery manufacturers, energy storage power station operators, third-party operation and maintenance organizations, and decommissioned recycling companies; The access levels are divided into four levels from high to low: Level 4, Level 3, Level 2, and Level 1. Among them, battery manufacturers are at Level 4, energy storage power station operators are at Level 3, third-party operation and maintenance organizations are at Level 2, and decommissioned recycling companies are at Level 1. S202. Construct a UID permission matrix based on permission level and data type; data types include: factory data, running data, maintenance data, and decommissioning data, and these data types are respectively labeled as category 1, category 2, category 3, and category 4 data. For the UID permission matrix It is a 4×4 matrix, where the first... Line 1 Column elements Indicates the first Level 1 permission level for the first Operation permissions for class data; the operation permission value can be 0, 1, or 2. When the value is 0, it means no permission; when the value is 1, it means read-only; when the value is 2, it means read and write. The values of the elements in the permission matrix are related to the permission level and data type. The permission level is denoted as... The data type is denoted as The rules for determining the value are as follows: when It is 4. When the numbers are 1, 2, 3, or 4, the element is 2. when It is 3. When the value is 2 or 3, the element takes the value 2; when It is 3. When the value is 1, the element takes the value 1; when It is 2. When the value is 3, the element takes the value of 2; when It is 2. When the value is 1 or 2, the element takes the value 1; when =1, When the digits are 2, 3, or 4, the element takes the value 1.

Bind the platform account's permission level to the corresponding UID permission matrix; The core data of the module is encrypted using an asymmetric encryption algorithm, and the decryption key is denoted as follows: ; Before obtaining the decryption key, the platform account needs to be authenticated based on the UID permission matrix. When the authentication is successful, the platform account's exclusive key is used to encrypt the decryption key, and then the encrypted decryption key is sent to the platform account. The platform account uses a dedicated key to decrypt the encrypted decryption key, and then uses the decryption key to decrypt the module's core data to obtain the module's core data.
[0025] S3. During the power plant registration and operation and maintenance phase, composite UIDs are identified, their permissions are verified, and they are dynamically updated. The detailed process is as follows: S301. Perform module entry verification and data synchronization; Power plant workers use handheld terminals with RFID reading capabilities to scan the composite UID of the module; the terminal automatically... Uploaded to the management platform, verified by the platform. The initial authorization code from the manufacturer is used to complete the data entry verification after it is approved. At the same time, the platform pushes accessible factory data to the terminal with readable permissions according to the power station's three-level permission level. S302. Update the dynamic status code according to the operation and maintenance operation, and then update the composite UID; Maintenance operations include module installation, testing, fault repair, and replacement; Updates to dynamic status codes include: Update status identifiers, update health values, and update the vendor's initial authorization code to the timestamp of each maintenance operation; The expression for updating health values is as follows: (5); in, For the updated health value, The health values are as shown before the update. The failure coefficient, , , The corresponding health coefficient is 1; the failure coefficient reflects the severity of the maintenance operation, with 0 for no failure, 0.1 for minor failure, and 0.3 for severe failure. Because the focus of health value determination differs depending on the length of time the device has been used, a dynamic health coefficient is set to improve the accuracy of health value determination. The specific relationship is as follows: Within one year of the energy storage module's use, the health value changes little, so we only need to focus on the measured health score. Therefore, we set the health coefficient corresponding to the measured health score to 0.8, and the health coefficients corresponding to the health value and fault coefficient before the update were both 0.1. After one year of use, the health value of the energy storage module fluctuates significantly, and the randomness of the measured health score increases. At this time, the health coefficient corresponding to the measured health score is set to 0.4, while the health coefficients corresponding to the health value and fault coefficient before the update are both 0.3.
[0026] The status indicators and their associated maintenance operations are as follows: The energy storage module is in storage and awaiting installation. The associated operation and maintenance is as follows: the energy storage module has completed the power station storage after authorization verification and is temporarily stored in the power station warehouse. It has not yet been installed in the energy storage cabinet / battery cluster. During installation, the associated maintenance operation is: the module is being shipped from the warehouse and is being installed on-site; Normal operation, associated maintenance operations are as follows: module installation completed, connected to BMS system, in normal charging and discharging operation state; During operation and maintenance, the associated operation and maintenance actions are: if a module has a minor abnormality or it is time for regular maintenance, stop operation for maintenance; Fault lockout, associated maintenance operations are: if a module experiences a serious fault, the system will automatically lock out and prevent operation; The fault repair is pending re-inspection. The associated maintenance operation is: the faulty module has been repaired, but a re-inspection has not yet been conducted to confirm whether it has returned to normal. The associated operation and maintenance procedures for the decommissioning assessment are as follows: the module operates until its design life / capacity decays to the threshold, the power plant submits a decommissioning application, and waits for the recycling company to assess it; The module is locked out of service, and the associated maintenance operation is as follows: the module completes the retirement assessment and is determined to be "prohibited from reuse".
[0027] Update the dynamic status code based on the updated status and health value: (6); in, This is the updated dynamic status code. This is the updated status identifier for the energy storage module. This is the timestamp for the maintenance operation.
[0028] The management platform sends the updated dynamic status code to the handheld terminal, which writes it into the module chip via RFID and binds the update record to the static base code, synchronizing it to the management platform database.
[0029] When maintenance is performed by a third-party maintenance organization, the management platform verifies the permissions through a permission matrix, granting only read and write permissions for maintenance data and read-only permissions for factory and operational data. After maintenance personnel complete their operations, any write operation to the updated dynamic status code must be approved by the power plant operator before it can be synchronized to the management platform.
[0030] Each time a dynamic status code is updated, it triggers an automatic update of the ledger on the management platform, generating a new ledger record. The record includes the static base code, operation type, operation time, status change content, and health value change, realizing the linkage update between physical operations and digital ledgers.
[0031] S4. During the decommissioning phase of the energy storage module, permission switching and full lifecycle data collection are performed. The detailed process is as follows: S401. The power station operator submits an application to decommission the energy storage module, indicating the reason for decommissioning, and associates the static basic code of the module with the decommissioning and recycling company. The management platform switches permissions and grants the decommissioning and recycling company read-only permissions for operation data, fault history, and lifespan data according to the permission matrix, while retaining the power station operator's historical data viewing permissions. S402. Recycling companies scan the static basic code using a handheld terminal. After the management platform verifies the permissions, it automatically collects the core data of the module's entire lifecycle and pushes it to the terminal in encrypted form. The core data of the entire lifecycle includes: static basic code, rated capacity, initial internal resistance, real-time health value, number of charge and discharge cycles, fault history, and service life.
