HTTP Interfaces and External Systems for Energy Storage Intelligent Due Diligence Reports

Data sources for energy storage intelligent due diligence reports include battery management systems (BMS) of energy storage power stations

What the data for this category looks like

Data sources for energy storage intelligent due diligence reports include battery management systems (BMS) of energy storage power stations, grid-connected dispatch platforms, operation and maintenance monitoring systems, and third-party inspection reports. Real-time operating data is updated every 5 seconds. Historical operation and maintenance data is archived by natural day. Third-party inspection reports are updated once. Data is packaged in structured JSON format, including fields such as unique power station identifier, device number, real-time charge-discharge power (unit: kW), rated energy storage capacity (unit: kWh), remaining power quantized value (unit: Ah), health status quantized value, grid-connected status, alarm level, and timestamp. No additional redundant information is included.

What constraints these characteristics impose on HTTP interfaces and external systems

The high-frequency updates of real-time operating data require interfaces to support low-latency responses. Single request timeout must be controlled within a reasonable range. Heterogeneous field naming differences across multiple data sources require interfaces to configure flexible field mapping rules to unify the output format of due diligence reports. Large volume of archived data requires interfaces to support paginated queries and data compression transmission. Energy storage data involves grid security compliance, so interfaces must carry signature verification parameters to prevent unauthorized access. In addition, differences in BMS output formats across energy storage manufacturers require interfaces to adapt to multiple data parsing templates to avoid data parsing failures.

How to configure the settings

Configuration ItemRecommended ValueRationale
API_REQUEST_TIMEOUT10 secondsAdapts to the low-latency requirements of energy storage real-time data, avoids interrupting data pulling due to timeout
FIELD_MAPPING_RULESCustom mapping per manufacturer preset templateAdapts to field naming differences across BMS manufacturers, unifies the output format of due diligence reports
POLLING_INTERVAL5 secondsMatches the update frequency of energy storage real-time operating data, ensures data timeliness
COMPRESSION_ENABLEDEnable gzip compressionReduces bandwidth usage for archived data transmission, improves interface response speed
SIGNATURE_VERIFICATIONEnable HMAC-SHA256 verificationMeets the security and compliance requirements of energy storage data, prevents unauthorized access
PAGE_SIZE100 entriesBalances response speed and single return volume for archived data queries, avoids interface overload

The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on relevant samples before finalizing settings.

Three Common Mistakes

  • Phenomenon: When the due diligence report generation interface is called, streaming data is returned. Clicking the power station detail link in the report only overwrites the current page, and a new tab cannot be opened. Cause: The target="_blank" attribute is not configured in the streaming output HTML fragment, or the interface does not return jump rule parameters that can be correctly parsed by the front end.
  • Phenomenon: The interface request returns a 403 Forbidden status code, and energy storage BMS data cannot be pulled. Cause: The SIGNATURE_VERIFICATION configuration is not enabled, or the signature verification parameter generation format is incorrect.
  • Phenomenon: The pulled due diligence report data has missing fields that do not match the expected power station parameters. Cause: FIELD_MAPPING_RULES is not configured, and the field naming rules of the target BMS are not adapted.

How to Confirm the Configuration Is Complete

  • Call the test interface, check if the fields of the returned data match the preset FIELD_MAPPING_RULES to confirm that field mapping takes effect.
  • Initiate high-frequency requests, check if the interface response time meets the API_REQUEST_TIMEOUT setting, and there are no timeout errors.
  • View interface logs to confirm that signature verification passes, and there are no 403-class errors.
  • Test paginated queries, confirm that the number of returned data entries matches the PAGE_SIZE configuration, and the pagination logic works correctly.
