Checked on 2026-07-16. This article is based on the EU Battery Passport requirements survey, Regulation (EU) 2023/1542 and public official materials. It does not promise certification, approval, marketplace display, sales, review or timing outcomes.
The EU Battery Passport is often misunderstood as a QR-code task that can be finished at the end of a project. In practice, the passport depends on product data, supplier evidence, documentation ownership and version control. The GOV.UK EU Battery Passport requirements survey updated in July 2026 also frames the topic as a preparation issue for companies facing upcoming battery passport requirements.
Start with product scope
Companies should first identify whether the product is a cell, module, battery pack, battery-containing product, repurposed product or remanufactured item. The data owner and evidence path may differ by product role, so the supplier file should not be built only after a customer asks for a QR code.
| Data area | Typical source | First question |
|---|---|---|
| Carbon footprint | LCA records, supplier data, process records | Can the version and boundary be traced? |
| Materials | BOM, SDS/MSDS, supplier declarations | Does the file cover key materials and components? |
| Performance | Test reports and technical specifications | Does the evidence match the same model? |
| Due diligence | Supplier policy, risk review and audit records | Is there an owner and retention rule? |
Do not leave supply-chain data in procurement emails
Battery passport preparation touches R&D, purchasing, quality, compliance and supplier management. The common weak point is not only a technical interface. It is unclear data ownership, inconsistent versions and supplier documents that cannot be traced back to the right model.
