8 fields that make a battery prototype acceptance record usable

An acceptance record should identify exactly what passed, under which conditions and for which revisions. Eight fields keep a sample demonstration from being mistaken for unrestricted production approval.

Published by Jinfan

What to bring to the review

  • Exact battery, host and relevant charger revisions
  • Confirmed requirements, proposed targets and unresolved questions kept separate
  • A responsible owner and evidence location for each decision

8 fields that make a battery prototype acceptance record usable

Use a row with field number, requirement, responsible party, revision, evidence link and decision. Keep the original measurements or documents available to the authorized project team. Mark missing evidence as open; do not replace it with an estimated pass.

  • 1. Sample identity: record the sample identifier and exact pack revision.
  • 2. System baseline: identify cell, electronics, charger, host and firmware revisions as applicable.
  • 3. Intended requirement: state the question the evaluation must answer.
  • 4. Conditions and method: retain the load, environment, instruments and relevant settings.
  • 5. Acceptance criterion: record the agreed limit and its responsible approver before deciding the result.
  • 6. Evidence: link the measured result to a trace, report or inspection record.
  • 7. Decision: distinguish accepted, failed, open and outside-scope items.
  • 8. Release scope: record the approver, decision date, limitations and follow-up owner.

Use the record to make a scoped decision

Write one row per requirement and preserve failed or inconclusive results alongside accepted ones. Reconcile the evaluated sample with the proposed production baseline. Authorize only the release scope supported by the record; later changes require a review of which evidence still applies.

Keep acceptance limits explicit

A transport document, a sample photograph and an appliance performance record answer different questions. None automatically closes the others.

Technical context and limits

PHMSA explains the lithium battery transport test-summary requirement. Use the actual model and revision when reviewing supplied documentation. A transport summary is separate from application performance and complete appliance qualification.

Common questions

Does the checklist count specify a product rating?

No. The number counts the fields in this worksheet. It is not a measured result, a quality score, a certification, a minimum order quantity or a promise of delivery time.

What should be shared with engineering first?

Share a non-confidential requirements summary, the relevant revisions and unresolved decisions through Technical RFQ. Agree a suitable private exchange before sending sensitive drawings or customer records.
