Context

What the battery passport means for validation

The battery passport under Regulation (EU) 2023/1542 is the digital product identity of a battery. Mandatory from 18 February 2027 for EV, LMT and industrial batteries above 2 kWh. Roughly 90 fields need sources. Many of those sources live in the spec and the test plan, not in a CRM.

2026 is the preparation year: data contracts, register connection, end-to-end evidence. Timeline, EPR and conformity sit in the EU Battery Regulation 2023/1542 — separate from the passport. Cevelar maps passport fields to spec and test, EU-hosted.

Mapping

Which passport fields need which evidence

Not every one of the roughly 90 fields comes from the lab. Validation teams fail when they plan everything as a test — or nothing.

Field (Annex XIII) Evidence type Typical source Where it breaks
Rated capacity Test report Performance test, OEM acceptance Spec without a measurement method
Carbon footprint Declaration + method LCA, delegated act Method missing from the spec
Recycled content Co, Ni, Li Supplier declaration Supply-chain mass balance Mistakenly planned as a lab test
State of health Measurement + defined method BMS log, second life “SoH” with no procedure
UN 38.3 transport Test report T.1–T.8 UN 38.3 Cell vs pack not locked
In-use safety IEC 62619 test report IEC 62619 §7 / §8 Standard number without a clause
Due diligence Co, Li, Ni, graphite Audit / OECD report Supply chain, not the lab Starts 18 Aug 2027 — not a homologation test
Unique identifier / QR Process + registry Art. 13, EU registry 2026 IT topic that still lands in specs

Impact

Market access needs evidence.

Feb 2027 Digital battery passport mandate
~90 fields Seven categories, three access tiers
  1. July 2026 · EU registry Central registry expected operational for DPP registration and customs checks.
  2. Feb 2027 · Digital pass Mandatory for EV, LMT and industrial batteries above 2 kWh, including QR and tiered access.
  3. Aug 2027 · Due diligence Due-diligence duties for in-scope economic operators under OECD-aligned standards.
  4. 2028 / 2031 · Recycled content Declarations and later minimum recycled quotas for new batteries placed on the market.

  2. Authorized operators Strong authentication: dismantling, schematics and safety data for repair and second life.
  3. Regulators Full access for market surveillance and customs: test reports, supply-chain audits, conformity evidence.

For validation & compliance

Passport fields without evidence stay risk.

OEM specs already mix passport obligations with UN 38.3, IEC 62619 and customer stress profiles. Cevelar structures requirements and keeps them linked to verification evidence, EU-hosted.

Software

What battery passport software has to cover

Battery passport software stores the roughly 90 fields, the QR code and the connection to the EU registry. From 18 February 2027 that record is mandatory for EV, LMT and industrial batteries above 2 kWh. The software does not produce conformity evidence.

Conformity evidence is the source behind the field: a test report for capacity, UN 38.3 and IEC 62619, a declaration for carbon footprint and recycled content, an audit for due diligence. A field without that source is an audit gap, whether or not the QR scans.

FAQ

Battery passport questions

The points validation and compliance teams still need to lock in 2026 — before February 2027 hard-starts.

What is a battery pass / battery passport?

A battery pass / battery passport is the persistent digital product identity of a battery under Regulation (EU) 2023/1542. It links the physical battery to lifecycle data from raw materials to recycling.

When does the battery passport become mandatory?

For EV, LMT and industrial batteries above 2 kWh, the digital battery passport is mandatory from 18 February 2027. The EU central registry starts in 2026.

What does the EU Battery Regulation require for the battery pass?

Roughly 90 data fields across seven categories, three-tier role-based access, connection to the EU central registry, and lifecycle traceability.

Battery pass vs EU Battery Regulation: what is the difference?

The EU Battery Regulation 2023/1542 is the full rulebook (sustainability, EPR, market access). The battery pass is the digital data layer: QR, registry, role-based access. Guide: EU Battery Regulation 2023/1542.

What should validation teams prepare in 2026 for the battery passport?

Data contracts, registry connectivity and end-to-end evidence. OEM specs already mix passport fields with UN 38.3, IEC 62619 and customer tests. Without spec → test → evidence mapping, passport fields stay unverified. Cevelar keeps that chain, EU-hosted.

Which batteries need a battery passport?

From 18 February 2027: EV, LMT and industrial batteries above 2 kWh. The Art. 13 QR code is calendar-aligned to the same date.

Which passport fields need a lab report?

Capacity, safety and transport tests need test reports. Carbon footprint and recycled content come from declarations and the supply chain. State of health needs a defined measurement method. Due diligence is an audit, not a lab test.

Is battery passport software enough without a test plan?

Software serialises fields and QR codes. It does not replace the source behind the field. A passport field without evidence from the spec or a test report stays an audit gap.
