Passport + QR per unit
Every single battery needs its own passport and a unique QR code - not the model, the unit.
EU Battery Regulation 2023/1542
The digital battery passport for every battery
Mandatory from February 2027. Batteriepasswerk is the battery passport software for manufacturers: create EU-compliant battery passports per unit - with QR code, aligned with DIN DKE SPEC 99100, no IT project required.

The starting point
The battery passport is mandatory - the data is not yet ready.
02
Data is scattered
Information sits in certificates, spreadsheets and with suppliers - barely anyone keeps it in one place.
03
Enterprise tools are too slow
Large compliance platforms are expensive and sluggish. Mid-sized companies need something that runs in days, not quarters.
The pain point
Why almost no one delivers this reliably today.
Three realities make the battery passport hard - and they all hit at the same time. That is exactly where we come in.
Data sits in 6+ sources.
Material certificates as PDFs, BOMs in Excel, LCA values from a consultant, supplier answers in email, serials from the ERP. No one keeps it in one place.
Manual consolidation per model: 3–8 weeks.
One passport per unit - not per model.
The passport is physical, per battery. A single approved model spawns thousands of serialised passports with a unique QR - ready to print or engrave.
Mass generation instead of copy-paste.
Market surveillance can check at any time.

Authorities, recyclers and customers all read the same QR - but in different roles. Gaps in the supply chain mean a shipment stop and personal liability for management.
A single missing value blocks the whole shipment.

- 01
Create a model
Maintain master data once - structured to DIN DKE SPEC 99100. Materials, chemistry, performance, due diligence.
Once per model - 02
Import serial numbers
Upload a CSV or Excel - and Batteriepasswerk generates thousands of passports including unique QR codes automatically.
Thousands at once - 03
Ship the QR codes
Print- and engraving-ready codes, plus the public passport page with role-based access for authorities and recyclers.
Per unit, GS1
Product preview
See at a glance which passports are ready - and where data is still missing.
The readiness cockpit shows the status of every battery against the criteria of the EU regulation. And with one click you switch to the public passport page — exactly what appears after scanning the QR code on the battery.

Learn moreSupply Chain Trust & Assurance
Data auditors can trust - cryptographically proven.
Authorities, OEM buyers and recyclers rely on your passport data. That is why Batteriepasswerk seals every change in a SHA-256 hash chain: tamper-evident, audit-proof and publicly verifiable - without blockchain overhead.
Sealed versions
Every change to a model or passport creates a new version. Its SHA-256 hash includes the hash of its predecessor - retroactive edits break the chain and surface immediately.
Audit-proof audit trail
Who, what, when: recorded automatically at the database level, append-only, impossible to delete or overwrite. Enforced in the platform core, not in app code.
Publicly verifiable
Every passport page carries its integrity proof, and an open verification endpoint validates the full chain on demand - for auditors without an account.
Traceable provenance
Supplier data and certificates with source and timestamp; professional access by recyclers and authorities is approved individually and logged without gaps.
How the hash chain works
Built for Art. 78 (g)/(h) of EU Battery Regulation 2023/1542: protection against manipulation and traceability of every change.
Trust anchor
Compliant - and connectable.
Structured to EU Battery Regulation 2023/1542 and DIN DKE SPEC 99100, QR per GS1 Digital Link, data hosted in the EU. Compatible with Catena-X and the Asset Administration Shell - without an enterprise IT project.

Frequently asked
What manufacturers ask most.
Do I need a separate passport for every battery?
Yes. The EU Battery Regulation requires a separate digital battery passport with a QR code per unit - not per model. Batteriepasswerk serialises thousands of passports automatically from a single model template.
What exactly does the EU Battery Regulation say?
Regulation 2023/1542 mandates a digital battery passport for EV, LMT and industrial batteries above 2 kWh from 18 February 2027, accessible via a QR code on the battery.
Is the battery passport a Digital Product Passport (DPP)?
Yes. The battery passport is the EU's first legally mandatory Digital Product Passport (DPP). A unique identifier, a QR code as data carrier, role-based data access - exactly the architecture the Ecodesign Regulation (ESPR 2024/1781) will require for many more product groups. With Batteriepasswerk you already produce a fully-fledged DPP today.
Do you calculate the carbon footprint?
No. You provide the LCA figure from your own calculation - we store it in a structured way and display it in the passport in line with the regulation.
Is this DIN SPEC 99100 compliant?
Yes. The data structure follows DIN DKE SPEC 99100, the QR code follows GS1 Digital Link. Data is hosted in the EU.
Can I use public funding?
Onboarding and digitalisation projects can be eligible for funding depending on the region and programme. Please check eligibility individually - we can support with documentation.
How do I create or generate a digital battery passport?
With battery passport software like Batteriepasswerk: you set up a battery model once with the mandatory data from Annex XIII, and the solution generates serialised passports including a QR code (GS1 Digital Link) for every unit - EU-compliant under Regulation 2023/1542 and DIN DKE SPEC 99100, with no IT project of your own.
Who does the 2027 battery passport obligation apply to?
The battery passport obligation applies from 18 February 2027 to manufacturers, importers and distributors placing EV, LMT or industrial batteries above 2 kWh on the EU market. Anyone who has not implemented the EU Battery Regulation by then risks market exclusion and fines.
What should manufacturers look for when choosing battery passport software?
When comparing battery passport providers, four points matter: conformity with EU 2023/1542 and DIN DKE SPEC 99100, mass serialisation instead of one-by-one editing, GS1 Digital Link QR codes per unit, and EU hosting with role-based access. You can find a side-by-side comparison of the approaches on our comparison page.
