Preparing for a Battery Passport Compliance Audit

Market surveillance authorities don't announce audits six months in advance. When an inspector requests proof that battery serial EU-EV-2027-XXXX has a valid passport, you have days — not weeks — to respond. Audit preparation is continuous, not episodic.

What Auditors Verify

• Passport exists for sampled serial numbers
• Public QR data matches physical label and declaration of conformity
• Carbon footprint methodology matches delegated act requirements
• Restricted fields accessible to authorized roles only
• Technical file and passport data are consistent (no contradictions)

Audit-Ready Documentation Pack

1. UID allocation log with production batch linkage
2. Passport commit timestamps and version history
3. Supplier data certificates and LCA study references
4. QR scan test records (date, device, result)
5. Corrective action log for any passport errors discovered pre-shipment

Quarterly Self-Audit Routine

Every quarter: random sample 20 published passports, scan QR, compare fields to ERP master data, verify carbon footprint still current. PassCell's dashboard and export tools support this workflow without custom reporting projects.

When Findings Occur

Document root cause, update affected passports, notify importers if market-placed units affected. Corrective speed demonstrates good faith to authorities — often reducing penalty severity.
