Automakers, suppliers and dealers in Germany and Austria must prepare now: the EU’s Digital Battery Passport becomes mandatory for electric‑vehicle batteries on 18 February 2027, but implementation on the ground is diverging. Germany has already aligned national law with the EU text; Austria still lacks a published companion law setting sanctions and administrative details. That split matters for production planning, compliance costs and second‑life recycling across the DACH market.

Where the rules stand

The battery passport requirement is written into Regulation (EU) 2023/1542: Article 77 fixes 18 February 2027 as the date from which every EV battery, every light‑means‑of‑transport battery and every industrial battery above 2 kWh placed on the EU market must carry a digital battery passport accessible via QR code.

Member‑state and standards infrastructure are moving fast. The EU’s Digital Product Passport registry was made operational in mid‑2026 and the Commission published guidance and data‑point lists through 2026 (the Commission’s data‑point guidance reached version 3.2 on 19 October 2026), leaving firms with 71 structured items they must prepare to supply for EV packs.

Germany has adapted national law: the German Battery Law Implementation Act (Batterierecht‑Durchführungsgesetz, BattDG) was adopted in 2025 to align domestic rules with the EU Batteries Regulation and to set national authorities and sanction frameworks. That gives German manufacturers and enforcement agencies a clear legal basis for compliance and penalties.

By contrast, Austrian authorities have told industry that a national “Begleitgesetz” (companion law) defining sanctions and administrative detail will be required — but, as of April 2026, that companion law had not yet been published, leaving the local sanction regime and procedural rules still subject to national drafting and delay. That gap creates legal uncertainty for Austria‑based importers, remanufacturers and recycling operators.

Technical standards and what to deliver

Standards bodies and technical committees are closing in on the passport’s data structure: CEN work on a technical specification for Digital Battery Passport data (FprCEN/TS 18363) was in formal vote in late 2026, documenting how public, restricted and market‑surveillance information should be split and exchanged. Firms will need IT systems that can host the passport, link a battery’s unique identifier and expose different data‑views to public users, legitimate interested parties and market authorities.

National enforcement will matter: member states set penalties under Article 93 of the Batteries Regulation. Guidance and trackers already show fines and enforcement ranges used around Europe; Germany’s enforcement guidance indicates administrative fines up to about €100,000 for certain breaches, a figure companies must factor into compliance risk models.

What this means for the market

For OEMs and suppliers in Germany and Austria the clock is short. Manufacturers must embed 71+ data points (chemistry, mass, SOH, carbon footprint metadata, provenance and more) into production IT, tie unique IDs to physical battery packs, and ensure the QR landing page and registry entries are correct by 18 February 2027. German firms benefit from an enacted BattDG and clearer national sanctioning; Austrian firms face a transitional risk if the national companion law is only finalised late, because enforcement practices and fines will be set at the national level.

Aftermarket players — workshops, remanufacturers and second‑life storage integrators — must secure access rights to passport data and update diagnostics to report state‑of‑health and reuse status; early investments in compliant traceability systems will reduce recall and market‑surveillance exposure. The Commission’s registry and the CEN technical work give a path, but national transposition differences mean cross‑border logistics and used‑battery trade between Germany and Austria will need legal checks before each shipment.
