What the data for this category looks like
Data sources for this category include cell grading equipment, manufacturing execution systems (MES), welding equipment, torque tools, BMS software version records, and EOL test benches. Data updates occur once per produced battery pack or energy storage cabinet, and are synchronized whenever a BMS software version changes. Daily documents include grouping rules, BOM lists, welding and torque records, BMS flashing records, insulation and voltage withstand reports, EOL test reports, and system configuration lists. Fields cover cell capacity, welding torque values, test voltages, BMS version numbers, with corresponding units: ampere-hours, newton-meters, volts, and version numbers.
What constraints these characteristics impose on the "HTTP Interfaces and External Systems" link
Multiple heterogeneous data sources require interfaces to support receiving request bodies in different formats, to adapt to the output specifications of various devices and systems. High-frequency, per-packet/per-cabinet update rhythms require interfaces to have low latency and batch processing capabilities, to avoid disrupting production cycles. Diverse document types and clear field requirements mean interfaces must support parameter validation, to ensure incoming inspection record fields are complete and accurate. Inspection results directly relate to system safety, so interfaces must have reliable authentication and failure retry mechanisms, to prevent incorrect data from entering the audit workflow.
How to set up configurations
The following configurations apply to FastGPT v4.17.0:
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Bearer {custom API key} | Complies with external system authentication specifications, prevents unauthorized access |
variables | Pass cell serial numbers, energy storage cabinet numbers, inspection batches | Links inspection records and system configurations for corresponding devices, enables metadata filtering |
responseData | Extract code, message, data fields | Uniformly handles return formats from different external systems, simplifies result parsing |
| Single request data limit | 50 entries | Matches the number of inspection records per pack or cabinet, avoids interface timeouts |
| Timeout period | 30 seconds | Adapts to the response delay of EOL test benches, aligns with business processing rhythms |
| Retry count | 3 attempts | Addresses temporary network fluctuations, ensures request success rates |
Three common mistakes
- Phenomenon: The interface returns a "parameter mismatch" error with status code 400. Cause: Required fields such as cell grading data and torque values are not included in the request, which does not comply with the validation rules of the external inspection system.
- Phenomenon: Interface calls time out, with no valid return results. Cause: The number of inspection records carried in a single request exceeds the processing limit of the external system, and the request volume is not adjusted according to actual business needs.
- Phenomenon: Audit results are not linked to the system configuration of the corresponding energy storage cabinet. Cause: Identification fields such as cabinet numbers are not passed through
variables, so correct process record data cannot be matched.
How to confirm the configuration is correct
- A test request carrying inspection records for a single energy storage system is sent, and the
codefield in the interface's returnedresponseDatais verified to match expected values. - Logs from the external system are reviewed, to confirm the
Authorizationauthentication information carried in the request is valid, and no unauthorized access-related errors are present. - A single batch request is simulated, to verify that the interface does not experience timeouts or data truncation issues, and the request volume is adjusted per actual business needs.
- Filtering conditions passed through
variablesare verified to accurately match the corresponding process record data, with filtering rules set per actual business requirements.
