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 Item | Recommended Value | Rationale |
|---|---|---|
API_REQUEST_TIMEOUT | 10 seconds | Adapts to the low-latency requirements of energy storage real-time data, avoids interrupting data pulling due to timeout |
FIELD_MAPPING_RULES | Custom mapping per manufacturer preset template | Adapts to field naming differences across BMS manufacturers, unifies the output format of due diligence reports |
POLLING_INTERVAL | 5 seconds | Matches the update frequency of energy storage real-time operating data, ensures data timeliness |
COMPRESSION_ENABLED | Enable gzip compression | Reduces bandwidth usage for archived data transmission, improves interface response speed |
SIGNATURE_VERIFICATION | Enable HMAC-SHA256 verification | Meets the security and compliance requirements of energy storage data, prevents unauthorized access |
PAGE_SIZE | 100 entries | Balances 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 Forbiddenstatus code, and energy storage BMS data cannot be pulled. Cause: TheSIGNATURE_VERIFICATIONconfiguration 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_RULESis 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_RULESto confirm that field mapping takes effect. - Initiate high-frequency requests, check if the interface response time meets the
API_REQUEST_TIMEOUTsetting, 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_SIZEconfiguration, and the pagination logic works correctly.
