The EU Digital Battery Passport: A Complete Guide for Manufacturers and Importers

If you manufacture or import batteries into the European Union, one of the most significant compliance requirements in the history of the industry is now less than nine months away. The EU Digital Battery Passport (DBP) mandate under Regulation 2023/1542 goes into effect on February 18, 2027, and the overwhelming majority of affected companies are not ready.

This guide covers everything you need to know: what a Digital Battery Passport is, which products are in scope, what data is required, how the technical standards work, and what you need to do before the deadline.

What Is EU Battery Regulation 2023/1542?

EU Regulation 2023/1542 — the EU Battery Regulation — came into force on August 17, 2023, replacing the previous Battery Directive (2006/66/EC). It establishes new requirements across the full battery lifecycle: sustainability, safety, labeling, due diligence, and end-of-life management.

At the center of the regulation is the Digital Battery Passport — a machine-readable record that must accompany every in-scope battery placed on the EU market. The passport is not just documentation. It is a live digital record tied to a unique identifier, accessible via a QR code, and submitted to a centralized EU registry.

The regulation applies to batteries placed on the EU market regardless of where they were manufactured. A battery made in Ohio, South Korea, or Poland and sold to a customer in Germany must comply with exactly the same requirements.

Does It Apply to Your Products?

The regulation categorizes batteries into five types. Three of them are subject to the Digital Battery Passport mandate effective February 2027:

If your company manufactures or imports forklift batteries, EV packs, industrial energy storage systems, or e-bike batteries for the EU market, you are in scope for the February 2027 deadline.

What Does a Digital Battery Passport Contain?

The required data fields are defined in Annex XIII of the regulation. The data is divided into three tiers based on who is allowed to see it.

Section 1 — Public Access

Visible to everyone, including consumers, recyclers, regulators, and the public — accessible directly from the QR code scan with no authentication required:

• Manufacturer name and contact information
• Battery model and chemistry
• Nominal capacity (kWh)
• Nominal voltage
• Expected lifetime (years and cycles)
• Carbon footprint declaration (kg CO₂e per kWh)
• Recycled content percentages (cobalt, lead, lithium, nickel)
• Hazardous substances
• Due diligence report (URL reference)
• Article 13(4) and (5) marking information
• Unique identifier and QR code

Section 2 — Legitimate Interest (Restricted)

Available to recyclers, repairers, and the European Commission — requires authentication under a "legitimate interest" framework defined by a Q4 2026 implementing act:

• Detailed material composition and part numbers
• Dismantling and disassembly information
• Safety data for handling and storage

Section 3 — Market Surveillance Authorities Only

Accessible exclusively to national market surveillance authorities:

• Test results demonstrating conformity
• Compliance documentation

Section 4 — Legitimate Interest (Lifecycle Data)

Available to recyclers, repairers, and second-life operators:

• State of Health (SoH)
• Battery status (original, repurposed, repaired, remanufactured)
• Charging and discharging data
• Accident history

Unique Identifiers and QR Codes

Every battery passport must be assigned a unique identifier that persists for the life of the battery and beyond. The identifier must be machine-readable, encoded in a QR code that resolves publicly without requiring a dedicated application.

Two identifier schemes are accepted under EN 18219, the harmonised standard for unique identifiers:

• GS1 GIAI (Global Individual Asset Identifier, AI 8004) — the preferred scheme. Requires a GS1 company prefix, which you obtain from your national GS1 member organization.
• ISO/IEC 15459 issuing agency codes — an alternative scheme for organizations registered as issuing agencies.

The QR code itself must conform to EN 18220, which specifies the GS1 Digital Link URI format, a minimum error correction level of Q (recommended for industrial environments), and the requirement that a DPP graphical indicator accompanies the QR code wherever it appears.

Critically: the identifier is permanent. Once a passport is issued for a battery, that identifier must remain valid and resolvable even if the manufacturer goes out of business, changes software vendors, or the battery is resold. This permanence obligation is one of the most commonly underestimated aspects of the regulation.

The EU Central DPP Registry

The EU Battery Passport uses a decentralized architecture. This is an important architectural decision that is often misunderstood:

• The full passport data — all the Annex XIII fields — is stored by the economic operator (or their authorized platform, such as PassportIQ), not by the EU.
• The EU Central Registry stores only: the unique identifier and a pointer (URL) to where the full data lives.
• When a regulator or consumer scans a QR code, the identifier resolves to the registry, which redirects to the hosted passport page.
• The registry validates semantic completeness at registration — incomplete passports will be rejected.

The technical standards for registry interaction are defined in EN 18222, which specifies mandatory REST API operations including CreateDPP, ReadDPPById, UpdateDPPById, and ReadDPPVersionByIdAndDate.

The EU Central DPP Registry is targeted to become operational in July 2026. This means the infrastructure will be live months before the February 2027 mandate — and early registration of passports will be possible well in advance of the deadline.

Timeline: Key Dates

The Technical Standards (EN 18216–18223)

Six harmonised standards were published on May 27, 2026 by CEN-CLC/JTC 24 under Standardisation Mandate M/604. Together they define the complete technical framework for DPP implementation:

Two additional standards are expected in September 2026: EN 18239 (access rights and security) and EN 18246 (data authentication). Presumption of conformity with the regulation is granted through compliance with these harmonised standards, though the Official Journal citation confirming this was still pending as of June 2026.

What Most Companies Are Getting Wrong

Treating it as a documentation exercise. The DPP is not a certificate or a PDF — it is a live digital record with mandatory API endpoints, a unique permanent identifier, and a registry submission. Companies that are building static documents will need to rebuild from scratch.

Underestimating the data collection burden. Carbon footprint (kg CO₂e per kWh), recycled content percentages for cobalt, lead, lithium, and nickel, and a due diligence report are all public-tier requirements. Many manufacturers do not currently collect or can not easily access this data from their supply chain.

Assuming it only applies to EU manufacturers. Any company placing batteries on the EU market — regardless of manufacturing location — is the responsible economic operator. US, Asian, and UK manufacturers that sell into Europe are fully in scope.

Confusing the registry architecture. The EU does not host your battery data. You host it (or your platform does). The EU registry stores only a pointer. If your platform shuts down, goes bankrupt, or cancels your subscription, those QR codes must still resolve. EN 18221 requires a business continuity plan for this scenario.

Starting too late. Data collection, identifier assignment, and passport creation take time — especially if you have hundreds or thousands of units. Companies that start in Q4 2026 will be managing a crisis; companies that start now have time to do it properly.

What to Do Before February 2027

1. Confirm which products are in scope. For each product line: is it an EV, industrial ≥2 kWh, or LMT battery placed on the EU market? If yes, it needs a passport.
2. Audit your data availability. Can you produce the Section 1 public fields for each unit? Carbon footprint and recycled content percentages are the hardest — start sourcing this from your supply chain now.
3. Establish your identifier strategy. Will you use GS1 GIAI (requires a GS1 company prefix) or ISO/IEC 15459? This decision has downstream implications for QR label production and registry submission.
4. Choose your platform or build path. Build-vs-buy for DPP infrastructure is not a trivial decision. A conformant platform must implement EN 18219–18223, submit to the EU Registry, maintain data permanently, and manage tiered access. Building this in-house is a substantial engineering project.
5. Register early. The EU Registry will be operational from July 2026. Early registration before the February mandate gives you time to identify and fix compliance gaps while there is still no enforcement pressure.
