Define whether OCV is used for incoming cells, module grading, PACK confirmation, or final shipment evidence.
Testing and quality
OCV testing checkpoints for cell and PACK production
A technical note for test timing, data traceability, sorting logic, station placement, and acceptance reporting.
Document objective
What this file should help verify
Help quality and automation teams decide where OCV testing sits in cell, module, and PACK workflows and what data must be accepted.
- Where OCV checks sit in cell, module, and PACK workflows.
- Sorting, NG handling, and traceability data buyers should clarify.
- Calibration and reporting evidence before FAT signoff.

Buyer FAQ
Questions this template should answer.
Is OCV a standalone station or a line-quality system?
It can be both. The key is whether the data supports sorting, traceability, and acceptance decisions, not only a pass/fail display.
What should buyers check in reports?
Timestamp, cell or module ID, voltage range, operator or station ID, NG reason, and export compatibility should be reviewed.
