What the data for this category looks like
Technical documentation data sources for battery PACK and energy storage system integration include cell capacity grading data, MES systems, welding equipment logs, torque tool records, BMS software version files, and EOL test bench test data. Document types include grouping rules, BOM lists, welding and torque records, BMS flashing records, insulation and voltage withstand reports, EOL test reports, and system configuration lists. Data updates occur once per produced battery pack or energy storage cabinet. Document updates are also triggered every time the BMS software version changes. Document fields include professional parameters such as cell capacity (unit: Ah), internal resistance (unit: mΩ), material codes, torque value (unit: Nm), insulation test voltage (unit: V), and BMS version number.
Constraints these characteristics impose on deployment and upgrade
Multiple heterogeneous data sources require interface docking between different devices and systems during deployment. This prevents data omissions. The high-frequency update feature requires configuring a real-time synchronization mechanism during deployment. This ensures every document change is quickly included in the review scope. The need for precise matching of professional fields requires presetting field mapping rules during deployment. This avoids review failure caused by differences in parameter units or naming. Error consequences involve safety links such as thermal management and insulation protection. This requires configuring a rollback plan during the upgrade phase. This ensures rapid recovery of the original configuration when anomalies occur.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 100–150 connections | Adapt to concurrent requests from multiple device data sources, avoid exceeding database connection limits |
REDIS_URL | Local port 6379 default configuration | Cache document shards and review results, reduce resource consumption from repeated calculations |
STORAGE_S3_ENDPOINT | Fill in according to the enterprise object storage service provider address | Store original technical documents uploaded in batches and review logs generated by FastGPT v4.17.0 |
FILE_TOKEN_KEY | 32-bit random string | Encrypt access tokens for document upload and download, prevent unauthorized access to sensitive technical documents |
PG_URL | Enterprise internal PostgreSQL instance address | Store review results and document version history, support subsequent traceability and auditing |
Three common errors
- Phenomenon: Review tasks restart infinitely after deployment. Logs prompt a token encoder configuration error. Cause:
REDIS_URLis not configured correctly, leading to cache failure. Token metadata for document shards cannot be parsed. - Phenomenon: Welding torque record documents are missing from review results. Cause: The log path of welding equipment is not added to the data source configuration. Corresponding documents are not included in the review scope.
- Phenomenon: High-voltage configuration verification fails after upgrade. Cause: The current BMS configuration document is not backed up in advance. The upgrade overwrites the original correct grouping rule parameters.
How to confirm correct configuration
- Perform a batch import of the full set of technical documents for a single energy storage cabinet. Check if FastGPT v4.17.0 can parse all document types normally and generate review tasks.
- Simulate a BMS software version upgrade to trigger the cross-review process. Confirm that review tasks start normally and generate verification results.
- Check the database connection count monitoring dashboard. Confirm that no
DB_MAX_LINKconnection limit exceeded errors occur during concurrent requests from multiple data sources. - Verify the document upload and download process. Confirm that the access token encryption logic takes effect. Unauthorized requests cannot obtain document content.
