Battery Passport: What companies need to know and how to implement it successfully
Why the Battery Passport is becoming a strategic turning point: The EU Battery Regulation (Regulation (EU) 2023/1542) defines how batteries must be produced, used and recycled in Europe. From February 2027, the EU Battery Passport will introduce a mandatory, digital data register that maps the entire life cycle of a battery. For companies in the automotive, energy, mechanical engineering, chemicals and electronics sectors, this means that data expertise will become a decisive success factor for market position, compliance and competitiveness.
- Sustainability & CO₂ transparency
- Raw material & supply chain traceability
- Safety & performance data availability
- Recyclability & circular economy
- Fair competition & market surveillance
Executive Summary - Battery Passport summarized
- Mandatory introduction from February 18, 2027: Applies to EV batteries, LMT batteries and industrial batteries >2 kWh
- Comprehensive data obligations: Over 100 technical, ecological, economic and safety-relevant data attributes - dynamically updated.
- Focus on the circular economy: CO₂ footprint (cradle to grave), recycled content, material origin, ESG risks and end-of-life data are becoming mandatory.
- Digital infrastructure opportunity: Manufacturers can set up tamper-proof, interoperable data supply - including sensor connection, ERP integration, supplier APIs.
- Opportunities for new business models: Data-based services such as battery-as-a-service, predictive health, second-life models and carbon-optimized supply chains are becoming possible.

- Supply chain risks
- Certifications & audit trails
- Compliance with CRMA & CSDDD
End-of-Life
- Recycling rates
- Dismantling instructions
- Secondary use data

Our solution - Why an end-to-end data model is the key to the battery pass
The Battery Passport is essentially a data project: it requires over 100 attributes, dynamic life cycle updates and consistent ESG, CO₂, origin and traceability data across suppliers, plants, logistics, OEMs and recyclers. Without a standardized data model, this quickly leads to fragmentation, conflicting requirements, duplicate maintenance and delayed compliance.
This is exactly where our solution comes in: We work with you to develop a harmonized end-to-end data model that integrates all relevant objects, processes, systems and stakeholders. It forms the functional and technical basis for a stable, scalable and consistent implementation of all battery passport initiatives – and reduces the risk of providing inconsistent, incomplete data.
- Reduced complexity through generalization with optimal mapping of technicality
- Common language across all areas (semantic harmonization)
- Standardized attribute lists & data logic
- Interoperable architecture for plants, logistics & suppliers
- Clear responsibilities & governance
- Automated, tamper-proof data supply
- Reporting, CO₂ calculation & tracking
With our end-to-end data model, you get:
- Complete transparency of all relevant battery pass data objects
- Consistent definitions & clear responsibilities
- a future-proof, interoperable database that supports all regulatory requirements
- Reduced project and integration complexity
- Risks, dependencies and implementation traps made visible at an early stage
- a robust basis for reporting, CO₂ accounting, supply chain traceability and end-of-life documentation
- Data & Process Assessment
Analysis of existing data flows, gaps, responsibilities and system architecture. - Supplier & data flow integration
Establishment of interoperable data chains across plants, suppliers and external partners. - Semantic modelling & attribute harmonization
Creation of a consistent, contradiction-free database across all stakeholders. - EU registry enablement & technical integration
Preparation for QR code logic, API connections and secure data provision. - Piloting & scaling
From proof of concept to factory pilots and global rollout.
Conclusion Battery Passport implementation - as an opportunity for strategic differentiation

Frequently asked questions about the EU Battery Passport
The EU Battery Passport is a digital register (Digital Battery Passport, DBP) that is accessible via a QR code on the battery and documents the entire life cycle of a battery – from raw material extraction to production, use, recycling and second use. It promotes transparency, sustainability and the circular economy as part of the European Green Deal and the EU Battery Regulation. The aim is to reduce dependencies on critical raw materials, improve ESG standards and enable data-based decisions, e.g. for repairs or recycling. For consumers, this means benefiting from detailed information on the origin of raw materials and carbon footprint and incorporating this information into their purchasing decisions.
The passport will become mandatory for electric vehicle (EV) batteries, batteries for light means of transport (LMT, e.g. e-bikes) and industrial batteries with a capacity of over 2 kWh from February 18, 2027.
It applies to EV batteries, LMT batteries and industrial batteries over 2 kWh, including stationary battery storage systems (SBESS). Portable batteries (e.g. in household appliances) are excluded unless they exceed the capacity limit. The regulation applies to all batteries placed on the EU market, regardless of country of origin.
The “economic operator” who places the battery on the EU market – typically the manufacturer, importer or distributor – is responsible for creating, maintaining and updating the passport. Suppliers must provide data, recyclers and authorities have access rights.
The Passport includes over 100 data attributes in three access levels (public, restricted, confidential): Environmental and sustainability data (e.g. CO₂ footprint, recycled content), performance and safety data (e.g. capacity, service life), traceability and due diligence (e.g. raw material origin, risks) and end-of-life information (e.g. recycling instructions). Data must be dynamically updated and verified by third parties.
Access is tiered: public for consumers (basic information), restricted for authorities, recyclers and authorized stakeholders (e.g. detailed recycling data) and confidential for manufacturers (e.g. proprietary formulas).
It creates competitive advantages through improved supply chain resilience, ESG performance and new models such as battery-as-a-service. It reduces risks (e.g. geopolitical dependencies), promotes innovation (e.g. AI-based life cycle analyses) and increases brand trust through transparency. In the long term, it supports the circular economy and net-zero targets.
Non-compliance can lead to market access bans, fines (up to millions depending on national law) and reputational damage. Authorities can recall products; for OEMs, this means supply chain disruptions and possible loss of sales. Early preparation minimizes risks.
