Battery passport · Annex XIII

What data does a battery passport need?

The battery passport's content is set by Annex XIII of the EU Batteries Regulation. Here it is in plain English — the data buckets, who can see what, and the numbers that draw the most scrutiny.

The data · Annex XIII

A battery passport carries the information in Annex XIIIof Regulation (EU) 2023/1542 — the battery's identity, its materials and chemistry, its carbon footprint, its recycled-content shares, performance and durability, supply-chain due diligence, and end-of-life information — disclosed at different access tiers depending on who is asking.

The data buckets

  • Identity & model
  • Composition & materials
  • Carbon footprint
  • Recycled content
  • Performance & durability
  • Supply-chain due diligence
  • Dismantling & recycling

What are the battery passport data buckets?

Seven broad groups: identity (unique ID, manufacturer, model, place and date of manufacture); composition (chemistry, critical raw materials, hazardous substances); the carbon-footprint declaration; recycled content for cobalt, lithium, nickel, and lead; performance and durability (capacity, expected lifetime, state of health); supply-chain due-diligence reporting; and dismantling and recycling information.

Who can see which fields?

Not everything is public. Annex XIII splits data across access tiers: some fields are open to anyone who scans the QR code; some are limited to people with a legitimate interest and the Commission; and some are reserved for notified bodies and market-surveillance authorities. The split lets a passport carry commercially sensitive detail without publishing it to the world.

Which numbers draw the most scrutiny?

The carbon footprint and the recycled-content shares. Recycled content isn't just declared — it has to hit rising minimum thresholds from 2031 and again from 2036 for cobalt, lithium, nickel, and lead, so the figure in the passport is the one auditors check. Treat those as first-class data you can evidence, not estimates.

When do you need this ready?

From 18 February 2027, per battery. The scope, dates, and how the passport fits the wider DPP framework are on the battery passport overview; if you sell across categories, the DPP checker shows which of your products need a passport and when.
