What This Data Entails
Data for energy storage financing daily reports is sourced from local energy administration project filing announcements, power equipment industry bidding announcements, and third-party energy storage industry databases. Updates run daily, covering new energy storage financing projects from the previous calendar day. Each data entry uses a fixed document structure with these fields: project name, energy storage technology type (such as lithium iron phosphate energy storage, compressed air energy storage), financing amount, investor entity, landing province, and filing date. Field specifications: Financing amount is measured in ten thousand yuan, filing date uses the YYYY-MM-DD format, energy storage technology type is an enumerated value, and landing province is the name of a domestic provincial administrative region.
Constraints for HTTP Interfaces and External Systems
Since data sources include multiple official and third-party platforms, interfaces must support parameter configuration for multi-source data aggregation to avoid duplicate pulls of the same project. The daily update rhythm requires that the interface pull interval must not be less than one calendar day. Otherwise, a large volume of duplicate data will be generated. The fixed field and enumerated value design requires that fields returned by the interface must match the parsing rules of external systems. Otherwise, field parsing failures will occur. Large financing amounts may result in large single-entry data volumes. Interfaces must support adjusting the upper limit of data returned per call to avoid transmission timeouts.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
external_sync_interval | 3600 seconds | Matches the daily update rhythm of energy storage financing daily reports, avoids duplicate pulls of the same batch of data |
returned_fields | ["project_name", "energy_storage_type", "financing_amount", "investor", "province", "record_date"] | Corresponds to the standard fields of energy storage financing daily reports, reduces invalid data transmission |
request_timeout | 600 seconds | Adapts to the pull time of large energy storage project financing data, avoids mid-call interruptions |
field_validation_switch | Enabled | Validates enumerated fields such as energy storage type and province, filters abnormal data returned by invalid data sources |
max_batch_count | 50 entries per call | Balances external system load and data pull efficiency, fits the reasonable range of a single interface call |
api_key_expire_days | 7 days | Complies with security specifications, while avoiding frequent key changes that disrupt external system integration |
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 case-by-case analysis, and it is recommended to test on your own samples before finalizing.
Three Common Mistakes
- Phenomenon: Interface calls return fields that do not match external system expectations, with some key data missing. Cause: The
returned_fieldsparameter is not configured correctly, and core fields of the energy storage financing daily report are omitted. - Phenomenon: Interface calls frequently return 401 authentication failures. Cause: The
api_key_expire_daysparameter is not set, and the default short-term key is used, resulting in expired keys that are not automatically updated. - Phenomenon: Excessive single pull data volume causes external system memory overflow. Cause: The
max_batch_countparameter is not restricted, and daily report entries exceeding the system's carrying capacity are pulled.
How to Confirm Proper Configuration
- Initiate a single interface call, check if the returned fields exactly match the configured
returned_fieldsparameter. - View interface authentication logs, confirm that the key is within the valid period and does not exceed the preset usage limit.
- Simulate consecutive interface calls, check that the call interval conforms to the
external_sync_intervalsetting, and no duplicate pull logic is triggered. - Pull test data containing large financing amounts, confirm that the interface does not return an abnormal status code due to timeout.
