What Is the Digital Battery Passport? A Guide for Battery Manufacturers and OEMs

In brief: From February 18, 2027, light means of transport (LMT) batteries such as e-bikes and e-scooters, industrial batteries above 2 kWh, and EV batteries placed on the EU market must carry a digital battery passport. The battery passport is the sector-specific implementation of the digital product passport under the EU Battery Regulation (EU 2023/1542) and documents material composition, carbon footprint, performance data, and recycled content across the battery's lifecycle.

What Is the Digital Battery Passport?

The battery passport is a digital record for an individual battery, accessible through a QR code on the device. It combines model-level information with data specific to that individual battery, including data generated during actual use. It is based on the EU Battery Regulation (EU 2023/1542), which has been in force since August 2023 and applies independently of the Ecodesign for Sustainable Products Regulation (ESPR).

Which Batteries Are Covered, and From When?

Requirement	Deadline
Labeling (manufacturing date, weight, chemical composition)	from 2026
Digital battery passport with QR code	from February 18, 2027
Batteries covered	LMT batteries, industrial batteries above 2 kWh, EV batteries

What Data Does a Battery Passport Contain?

• Material composition, including lithium, cobalt, and nickel

• Carbon footprint of manufacturing

• Performance and durability data

• Recycled content and recycling information

• Due diligence evidence along the supply chain

Why This Is More Than a Compliance Formality for Manufacturers and OEMs?

The data behind a battery passport comes from multiple internal and external systems: raw material suppliers, cell manufacturing, pack assembly, and in some cases the battery's actual operational history. Due diligence policies and carbon footprint declarations are considered the most demanding milestones and, according to industry estimates, should be in place at least twelve months before the February 2027 deadline. Companies that start data collection only shortly before the deadline risk being unable to issue a complete, verified battery passport in time.

How Spherity's VERA Supports Battery Manufacturers and OEMs

VERA, Spherity's platform for digital product passports, is built on W3C DID/VC. Every battery receives its own digital identity (DID) along with signed, verifiable claims covering material, origin, and compliance. VERA-X connects this identity to existing industry data spaces and is certified for Catena-X and Manufacturing-X, which matters in particular for OEMs already connected to automotive data spaces.

Frequently Asked Questions About the Digital Battery Passport

1. When does the battery passport become mandatory? From February 18, 2027, for LMT batteries, industrial batteries above 2 kWh, and EV batteries.

2. Is the battery passport part of the ESPR? No. It is based on the standalone EU Battery Regulation (EU 2023/1542), in force since 2023 and following its own timeline.

3. How much lead time does preparation typically need? Industry estimates suggest at least twelve months for due diligence and carbon footprint processes ahead of the deadline.

Next Steps

Companies manufacturing batteries for light transport, industrial use, or electric vehicles should begin collecting material, origin, and carbon footprint data now, not in 2027. To learn more about our Digital Product Passport solution, VERA, reach out to Spherity directly.
