What this category of data looks like
This category of data is generated across the full production lifecycle of battery packs, energy storage cabinets and BMS systems. Data sources include cell grading data, MES systems, welding equipment, torque tools, BMS software version records, and EOL test bench data. Data is updated once per produced battery pack or energy storage cabinet, and synchronized whenever a BMS software version change occurs. Daily retained documents include grouping rules, BOM lists, welding and torque operation records, BMS flashing logs, insulation and voltage withstand reports, EOL test reports, and system configuration lists. Data fields include cell parameters, assembly torque values, software version numbers, test voltage and current values, and more. There are no unified fixed units, with adjustments made based on the corresponding equipment or test item.
What constraints do these characteristics impose on the "HTTP Interfaces and External Systems" link
This category of data originates from multiple sources and is updated per individual device. HTTP interfaces must support querying by production batch and BMS version number. This prevents timeouts caused by pulling full datasets. Differing formats across data sources require interfaces to support multi-type data structure conversion. Interfaces must adapt to structured logs from welding equipment and test report formats from EOL test benches. High-priority insulation test and BMS flashing data requires the interface to configure authentication parameters. This ensures secure data transmission. Single data volume fluctuates with battery pack or energy storage cabinet scale. Sufficient request duration must be reserved. This prevents request failures caused by excessive data transmission volume.
Configuration Settings
The following configurations apply to FastGPT v4.17.0, and meet the quality traceability scenario requirements for battery PACK and energy storage system integration.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Authorization | Bearer {custom access key} | Secures access permissions for external data source interfaces, preventing unauthorized data pulling |
variables | {"batch_id": "production batch number", "bms_version": "BMS software version"} | Matches the core requirement of querying data by production batch and BMS version for this category |
responseData | Return only cell parameters, welding torque, insulation test results, EOL test results | Filters redundant fields, reduces interface response data volume, and improves query efficiency |
| Request timeout duration | 600 seconds | Adapts to the transmission duration of full production data for a single battery pack, preventing timeouts caused by fluctuating data volume |
| Failure retry count | 2 times | Addresses temporary request failures caused by on-site production network fluctuations, ensuring stable data pulling |
| Single query limit | 1 set per request | Matches the business scenario of pulling data per individual device for this category, preventing excessive resource occupation caused by batch pulling |
Three Common Misconfigurations
- Symptom: HTTP interface returns empty content. Cause: The
variablesparameter is not configured correctly, and the production batch or BMS version is not passed as a query condition. This prevents the interface from matching data for the corresponding production batch. - Symptom: Interface request returns 401 Unauthorized status code. Cause: The
Authorizationparameter is not configured correctly, a valid access key is not added, or the key format does not meet system requirements. - Symptom: HTTP response input parameters cannot be added. Cause: Variables are not defined in the required JSON format, or variable names contain special characters that cause parsing failure.
How to Verify Correct Configuration
- Call the test interface, pass a known production batch number, and check whether the returned
responseDatafield includes preset business-related content such as cell parameters and welding torque. - Check the format of the
Authorizationparameter, confirm that theBearerprefix plus a valid access key is used. Use an interface authentication test tool to verify whether access permissions are normal. - Adjust the timeout duration of the test request, confirm that single battery pack data can be pulled within 600 seconds, and prevent request failures caused by timeout.
- Test the transfer of input parameters, confirm that the batch number and version number in the
variablesparameter can be correctly identified by the interface and used for data query.
