What the data for this category looks like
Energy storage industry research reports for financial investment scenarios originate from public research reports of electric power equipment industry associations, securities firms' research institutes, grid operators, and energy storage manufacturers. Update cycles include monthly industry dynamic reports, quarterly in-depth analysis reports, and real-time interpretation documents released after policy updates. Documents follow multi-chapter formats, containing policy summaries, installed capacity statistics, upstream and downstream industrial chain analysis, project cases, and cost calculations. Fields include energy storage installed capacity, cycle life, and levelized cost of electricity, with corresponding units of GW/Wh, cycles, and yuan/kWh respectively. Some documents also include grid connection standard numbers and detailed technical parameters.
What constraints do these characteristics impose on deployment and upgrade
Multi-source document formats include PDF, Word, and web pages. Deployment requires compatible configuration for multiple parsing engines. Long documents with high information density require adjustments to segmentation and context window parameters to prevent truncation of key information. Differences in update cycles require configuring a flexible trigger mechanism for incremental indexing. This mechanism meets the needs of both monthly regular updates and policy-related real-time updates. Specific fields and units require configuring field mapping rules during retrieval. These rules ensure consistent unit matching and avoid deviations in retrieval results caused by unit ambiguity.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single energy storage niche research reports for financial investment often contain large numbers of charts and appendices, with a volume of over 500 MB |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long document parsing takes significant time, and the default threshold cannot cover the complete parsing process |
maxContext | 8000–12000 characters | Energy storage research reports have high paragraph information density; long context can retain complete industrial chain logic and data associations |
Number of retrieved results | Top 10–15 | Energy storage research reports have many niche dimensions; sufficient retrieved results are needed to cover different investment scenarios such as battery cells, inverters, and policies |
Similarity threshold | 0.72–0.78 | Avoid retrieving generic industry reports, and accurately match exclusive keywords for energy storage niche scenarios |
INDEX_INCREMENT_INTERVAL | 3600 seconds | Balance the investment needs of monthly regular research report updates and policy-related real-time updates |
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: Knowledge base search responses time out and return a 504 status code. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and long document parsing time exceeds the default threshold. - Phenomenon: An
EMFILE: too many open fileserror appears during Docker deployment. Cause: The file handle limit of the Docker container is not adjusted. Multi-document indexing tasks occupy a large number of file handle resources. - Phenomenon: Retrieved results include a large number of non-energy storage generic industry reports. Cause: The
similarity thresholdis set too low, and exclusive keywords for energy storage niche scenarios are not accurately matched.
How to confirm the configuration is complete
- Upload a single energy storage research report PDF larger than 500 MB, confirm that the parsing task completes within the preset time.
- Enter queries such as "2024 energy storage installed capacity", verify that the retrieved results include matching energy storage-related data fields.
- View Docker container logs, confirm that incremental indexing tasks trigger according to the preset cycle and have no errors.
- Adjust the
similarity thresholdto 0.7, compare changes in the number of retrieved results, and confirm that the parameter configuration takes effect.
