A Battery Passport depends on structured product data, but the data is only as strong as the source evidence behind it. Lithium Record can sit below the passport as a source-file vault and verifier handoff layer. 1
This spoke belongs to the EU Battery Regulation Lithium Records pillar at /eu-battery-regulation-lithium-records/.
Evidence beneath the passport
Regulation (EU) 2023/1542 introduces digital battery passport obligations for relevant batteries. The passport layer needs data fields, access rules, and product identifiers. The lithium evidence layer needs documents, provenance statements, carbon-footprint inputs, and file integrity records. Keeping those layers separate makes the system easier to audit because a passport data point can point back to a source record without asking the source vault to become the passport platform.
Handoff fields
A useful handoff record should include battery family, lithium material, supplier document title, issue date, hash, permanent URL, data category, and limitation note. It should also link sideways to carbon-footprint and due-diligence pages because passport questions often cross technical, environmental, and supply-chain boundaries.
What the page must not imply
This page must not say Lithium Record issues a regulated Battery Passport, validates passport fields, or satisfies access-control obligations. It can say the platform creates a verifier-ready source URL and hash for customer-uploaded lithium documents that may support a passport workflow.
