Drafting of Process Documents and Exception Reports for Battery PACK and Energy Storage System Integration: HTTP Interfaces and External Systems

What the data for this category looks like

Core data for this category originates from cell grading equipment, production MES systems, welding torque tools, BMS software, EOL test benches, and similar equipment. Daily generated documents include grouping rules, BOM lists, welding torque records, BMS flash logs, insulation and voltage withstand reports, EOL test data, and system configuration lists. Data updates occur each time a battery pack or energy storage cabinet finishes production. Updates also trigger when the BMS software version changes. Fields include cell capacity (unit: Ah), internal resistance (unit: mΩ), welding torque (unit: N·m), insulation resistance (unit: MΩ), BMS version number, charge-discharge voltage (unit: V), and similar metrics. The data size of a single process document ranges from 800 to 1200 characters. This page was written based on FastGPT v4.17.0.

What constraints these characteristics impose on HTTP interfaces and external systems

Data sources for this category are scattered, and update frequency is high. HTTP interfaces must support batch pulling and real-time synchronization of data from multiple devices. Business requirements for multiple fields require interfaces to support specifying returned fields, to avoid redundant data transmission. Severe potential error consequences require interfaces to include authentication and retry mechanisms. These mechanisms prevent abnormal data from flowing into process documents and exception reports. For intranet deployment scenarios, some devices cannot directly access the internet. Interfaces must support HTTP proxy configuration with username and password, to adapt to intranet access needs.

How to set configurations

Configuration ItemRecommended SettingRationale
AuthorizationBearer {fastgpt_api_token}Complies with HTTP interface authentication standards, and supports integration with external systems from multiple manufacturers
variables{"product_type": "pack", "report_scope": "eol"}Passes category-specific business parameters, to distinguish between different types of process documents and exception reports
responseDatainclude:["torque_value","insulation_resistance","bms_version","related_docs"]Only returns core fields required for process documents and exception reports, to reduce data transmission volume, and supports returning associated knowledge base document information
Request timeout300 secondsAdapts to data collection delays in welding, EOL testing and other links, to avoid interface interruptions
HTTP proxy configurationProxy address + port + username and passwordAdapts to internet access requirements in intranet deployment scenarios, and resolves issues where intranet servers cannot directly access external data sources

Three common misconfigurations

  • Phenomenon: The interface returns the Data too long for column 'models' error. Cause: The length of variables or custom fields is not limited, causing incoming BOM details or cell parameters to exceed the storage limit of database fields.
  • Phenomenon: Non-login links cannot load process documents when accessed across devices. Cause: The cross-domain whitelist for the interface is not configured, preventing external devices from calling FastGPT interfaces to obtain data via links.
  • Phenomenon: The responseData field returned by the interface is empty. Cause: Required business fields are not specified, so the interface fails to match the cell and test data required for process documents.

How to verify correct configuration

  • Call the test interface, check if the Authorization authentication header is correctly carried, and confirm the returned status code is 200.
  • Pass preset variables parameters, check if the responseData returned by the interface includes category-specific business fields.
  • Test interface calls in an intranet proxy environment, confirm that external data sources can be accessed normally, and no connection timeout errors occur.
  • Simulate exception scenarios to trigger the interface, check if field data required for exception reports can be generated correctly.
