01 · QUESTION / INTENT
Build a controlled evidence pack that supports design, incoming quality, safety review and long-term change management.
02 · DIRECT ANSWER
Request more than a datasheet: exact model identity, controlled specification and drawing, electrical/thermal limits, life-test conditions, safety and transport evidence, production-site and lot traceability, quality-control plan, sample reports and a change-notification agreement. Each item needs an owner, revision, date and scope.
03 · DECISION TABLE
| Decision factor | Decision direction | Confirm before approval |
|---|---|---|
| Design evidence | Needed to define BMS, cooling, compression and protection. | Limits, tolerances, curves and drawings—not headline values only. |
| Quality evidence | Needed to control incoming lots and deviations. | Control plan, capability, lot COA and nonconformance process. |
| Compliance evidence | Needed to map model to product and route obligations. | Exact model/configuration, issuing body, date and applicable edition. |
04 · ENGINEERING EXPLANATION
Create an evidence register with requirement, document, model/revision, product layer, owner, status and expiry/change trigger. Open items should become test or contract actions; a folder of unindexed PDFs is not an evidence system.
05 · APPLICATION / MARKET MAPPING
BESS banks, insurers and EPCs may need different extracts from the same evidence register. Keep cell evidence linked to module, rack, container and shipment evidence rather than mixing the layers.
06 · EVIDENCE AND TEST CONDITIONS
- Controlled technical package and model-to-document matrix.
- Sample, pilot and production-lot reports with acceptance criteria.
07 · RISKS / NOT SUITABLE WHEN
- Do not accept a certificate whose model list or configuration cannot be matched.
- Do not treat marketing cycle-life charts as warranty evidence.
08 · FAQ
Should all evidence be public?
No. Publish safe summaries; manage controlled, confidential and project-specific files through access rules.Who owns the register?
One accountable project owner, with engineering, quality and compliance owners for their respective items.BUYING COMMITTEE ANSWERS
