What is a digital battery passport?

A digital record, reachable from a QR code on the battery, that exposes the ~80 Annex XIII attributes (identity, carbon footprint, recycled content, due diligence, performance) required by EU Regulation 2023/1542, with tiered access for the public, parties with a legitimate interest, and authorities.

When is it mandatory?

From 18 February 2027 for LMT batteries (any capacity), industrial batteries over 2 kWh and electric-vehicle batteries placed on the EU market. Supply-chain due-diligence obligations apply from 18 August 2027.

Can I try battery passport software for free?

Yes. LMTPASS has a free plan with 15 passports per month and up to 5 battery models, including Annex XIII validation, a QR code and a public passport page, with no credit card required.

What happens if my battery has no compliant passport?

Penalties are set by each member state, but the concrete risk is market access: a non-compliant battery can be blocked from the EU market, withdrawn, or rejected by manufacturers and distributors that require a valid passport.

Digital Battery Passport Software: How to Choose a Provider

A digital battery passport is a QR-accessible record of a battery's identity, carbon footprint, recycled content, supply-chain due diligence and performance, mandated by EU Regulation 2023/1542 (Annex XIII). From 18 February 2027, every LMT, industrial (over 2 kWh) and EV battery placed on the EU market must carry one. This guide explains what compliant passport software must do and how to evaluate a provider.

Key facts

The digital battery passport is mandatory from 18 February 2027 for LMT, industrial (>2 kWh) and EV batteries placed on the EU market.
Each passport must expose roughly 80 data attributes defined in Annex XIII, reachable from a QR code on the battery.
Access is tiered: public data for anyone, restricted data for parties with a legitimate interest, and full data for authorities.
The hardest part is not generating the QR code — it is collecting and validating the data that lives with cell makers and suppliers.
LMTPASS offers a free plan (15 passports/month, 5 battery models) so you can produce a real compliant passport before committing.

What to watch out for

Many tools generate a QR code but leave you to gather Annex XIII data from suppliers by hand.
Passport data must stay accurate over the battery's life (state of health, second life, ownership changes).
Buyers, marketplaces and authorities each need a different level of access to the same passport.

How LMTPASS fits

Guided builder with built-in Annex XIII validation and a real-time compliance score, so you know what is missing before you publish.
Managed supplier-data collection: request, chase and validate the carbon-footprint and material data held by your suppliers.
Three-tier access (public, legitimate-interest, authorities) with audited reads and Ed25519-signed Verifiable Credentials.

8 criteria for evaluating digital battery passport software

Criterion	Why it matters
Annex XIII coverage	All ~80 mandatory attributes must be supported, not just identity and a QR code.
Built-in validation	A compliance score catches missing or invalid fields before a passport is published or rejected by a buyer.
Supplier-data collection	Most passport data lives with suppliers; software that helps you gather and validate it removes the real bottleneck.
Tiered access control	Annex XIII requires public, legitimate-interest and authority access levels with auditable reads.
Interoperability	GS1 Digital Link, AAS submodel export and Verifiable Credentials let passports be read by other systems and registries.
Bulk + API	CSV/Excel import, REST API and webhooks matter once you have hundreds or thousands of serial numbers.
EU hosting & GDPR	Data residency in the EU and a clear GDPR posture are expected by industrial buyers.
Time to first passport	A free plan or trial that produces a real, valid passport is the fastest way to de-risk the choice.
