What data looks like for this category
Core data for this category covers the entire production workflow of battery packs, energy storage cabinets, and BMS systems. Daily documents include cell grouping rules, material BOM lists, welding and torque operation records, BMS flashing logs, insulation and pressure resistance test reports, EOL test records, system configuration lists, and more. Data sources include cell capacity grading data, workshop MES systems, welding equipment, torque tools, BMS software version repositories, and EOL test benches. Data is updated once per produced pack or energy storage cabinet, and also updated whenever a BMS software version changes.
What constraints do these characteristics impose on HTTP interfaces and external systems
This category has high data update frequency, with single-unit data volume matching individual production units (single pack or single cabinet). This requires HTTP interfaces to support high-frequency, small-batch requests to avoid batch interface timeouts. Document fields include precise numerical values with units, such as torque values, test voltages, cell capacities, and others. Interfaces must support structured parameter passing to ensure consistent field formatting. Data is linked to production batches and software versions, so interfaces must support retrieval by batch or version, and also be compatible with heterogeneous data formats uploaded by different production equipment. Since errors may pose system security and downtime risks, interfaces must include error retry and status verification mechanisms to prevent incorrect data from entering the Q&A system.
How to set configurations
The following configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Permission Verification | Enable Authorization header verification, use the Bearer {API key} format | Complies with HTTP interface security specifications to prevent unauthorized access |
| Context Variables | {"batch_no": "", "bms_version": "", "user_id": ""} | Adapts to the category's need to retrieve process documents by production batch and BMS version, as well as multi-user session differentiation requirements |
| Response Data Filtering | Only return matching process specification and technical standard fragments | Reduces interface data transmission volume and improves Q&A response speed |
| Request Timeout Setting | 600 seconds | Adapts to the time required for single complex process queries to avoid request interruptions |
| Failure Retry Strategy | Retry 2 times after failure, with a 10-second interval | Addresses request failures caused by workshop network fluctuations |
| Request Body Size Limit | No more than 1000 MB | Adapts to transmission requirements for batch process document retrieval |
Three common errors
- Phenomenon: The interface returns a 401 unauthorized error, or prompts that the API key is invalid. Cause: The
Authorizationheader is not configured correctly, or the key format is incorrect, and the standard Bearer prefix is not added. - Phenomenon: When multiple business system users connect, different users' chat records cannot be distinguished, resulting in session confusion. Cause: A unique user identifier is not passed in the request variables, and the session context is not bound by user dimension.
- Phenomenon: Calling an external interface returns a connection failure, or prompts that the configuration channel is missing. Cause: External interface configuration parameters are not updated synchronously, or the interface address and key are changed but not modified synchronously.
How to confirm the configuration is correct
- Call the test interface, pass valid production batches, BMS versions, and user identifiers, and check if the returned
responseDatacontains matching process document fragments. - Simulate requests from two different users, and check if the session contexts are independent, with no chat record confusion.
- Simulate an interface call failure scenario, and check if the preset retry mechanism is triggered, with expected error prompts returned.
- Verify the
Authorizationheader configuration, call the interface with a valid key, and confirm that no unauthorized error is returned.
