The EU Battery Regulation and battery passport
Preparing for the EU battery passport takes more than collecting fields and publishing a QR code. Organizations need to establish which battery each value describes, which product configuration, manufacturing plant, and production period it applies to, what evidence supports it, and who is permitted to access it. This white paper translates EU Battery Regulation obligations into practical data requirements for compliance, R&D, manufacturing, procurement, and IT teams.
Battery teams may already hold extensive performance and development data while still struggling to retrieve the production inputs, supplier evidence, version history, and lifecycle records needed to support declarations. Connecting those records is the foundation for reliable passport information, not a task to address after publication.
What data does an EU battery passport need?
The data an EU battery passport needs depends first on applicability. Battery category, product characteristics, thresholds, and application conditions determine which obligations apply, so they should be established before anyone selects passport fields. From there, teams need to separate battery-model, model-and-plant, production-period, and individual-battery information.
Each declared value also needs its supporting evidence: product definitions, production activity data, supplier evidence, methods, calculations, and approvals. Carbon footprint, recycled content, performance, durability, and due-diligence obligations each translate into different evidence requirements. Managing this as part of regulatory management keeps declarations versioned and traceable.
Who this white paper is for
This white paper is for compliance, R&D, manufacturing, procurement, and IT teams preparing battery passport data, with roles for quality, security, data stewardship, service, and lifecycle partners. It separates legal requirements from recommended implementation controls, and it supports data planning rather than replacing specialist regulatory interpretation.

What's inside
Inside this white paper:
- Why battery category, product characteristics, thresholds, and application conditions must be established before selecting passport fields
- How to distinguish battery-model, model-and-plant, production-period, and individual-battery information
- How carbon footprint, recycled content, performance, durability, and due-diligence obligations translate into different evidence requirements
- What to preserve behind declared values, including product definitions, production activity data, supplier evidence, methods, calculations, and approvals
- A connected data model for battery identity, configuration, evidence packages, declarations, production genealogy, and lifecycle events
- How to assess supplier, material, and production changes without automatically treating every change as a new battery model
- How to manage public and restricted information, unique identifiers, QR-code access, interoperability, and passport continuity
- A practical pilot approach and readiness measures for evidence coverage, change traceability, retrieval, access controls, and individual-record resolution
Read the white paper to build a dependable chain from regulatory obligation to applicable product, from published value to supporting evidence, and from individual battery to lifecycle history.
FAQs
The EU battery passport is an electronic record containing information about a battery model and the individual battery, including specified information arising during use. The battery passport connects a physical battery to applicable product, performance, status, and lifecycle information. For data planning, the key distinction is between shared model information and records specific to an individual battery.
The EU Battery Regulation and Battery Passport white paper is designed for compliance, R&D, manufacturing, procurement, and IT teams preparing battery passport data. Quality, security, data stewardship, service, and lifecycle partners also have roles in maintaining evidence, permissions, updates, and continuity. The white paper helps these functions agree on record ownership, authoritative sources, identifiers, and relationships.
Organizations should define applicability before battery passport fields because battery categories and obligations have different scopes, thresholds, exemptions, and application conditions. A universal field list can hide which information a product actually requires and when. A controlled applicability record connects classification rationale, product characteristics, market context, obligations, timing, and review history, so changes can trigger reassessment.
Battery-model data describes shared technical characteristics and the applicable product definition. Individual-battery data identifies a physical battery and connects it to its configuration, production genealogy, passport, and lifecycle events. Some information applies at model-and-plant or production-period level. Keeping these levels distinct prevents a declared value from being copied across batteries without preserving where and when it applies.
Evidence for declared battery information depends on the information type. A declared value may need links to the product definition, bill-of-materials version, manufacturing plant, production period, supplier records, controlled test protocols, results, calculations, methodology version, and approvals. Treating declarations as versioned records with explicit scope and evidence, not document attachments, shows which declaration supported a battery and how later changes were handled.
