What Is a Battery Passport?

The short definition

A battery passport is a digital record - reachable through a QR code on the battery - that carries identity, sustainability, performance, and supply-chain data for a specific battery. It is the first legally mandated form of Digital Product Passport in the EU, and it is set directly by the Battery Regulation (EU) 2023/1542, not by the broader ESPR framework.

The binding application date is 18 February 2027. From that day, the batteries in scope cannot be placed on the EU market without a compliant passport.

Which batteries need a passport

The passport obligation does not apply to every battery. Under Regulation (EU) 2023/1542 it applies to three categories:

• EV batteries - traction batteries for electric vehicles.
• Industrial batteries with a capacity above 2 kWh.
• LMT batteries - light means of transport, such as e-bikes and e-scooters.

Small portable batteries (the AA cells in a remote, for example) are covered by other parts of the Battery Regulation but are not subject to the battery passport itself. If you make, assemble, import, or place EV, LMT, or industrial batteries above 2 kWh on the EU market, the 2027 date is yours.

What data the passport carries

The battery passport is far richer than a label. The Battery Regulation defines the data set, and Annex XIII sets out the items the passport must hold. In practice the data falls into a few groups:

A key point: some of this data is dynamic. State of health and cycle data are not set once at manufacture - they are expected to be updated through the battery's life, for example after refurbishment, repurposing, or a change of owner.

Who issues the battery passport

There is no central authority that hands out battery passports. The obligation sits with the economic operator placing the battery on the EU market - normally the manufacturer that markets the battery under its own name or trademark. If that manufacturer is outside the EU, the duty shifts to the EU-based importer or the manufacturer's authorised representative.

That responsible operator must create the passport, populate it with correct data, and keep it accurate and available. The data carrier (a QR code) must be printed or engraved on the battery so anyone can scan through to the record.

Tiered access: not everything is public

The battery passport uses tiered transparency. Different audiences see different data:

• The general public sees headline information - identity, basic sustainability data, and handling or recycling guidance.
• Operators with a legitimate interest - repairers, refurbishers, recyclers, and second-life operators - get deeper technical data they need to do their job.
• Market surveillance authorities and the Commission get the fullest view, including commercially sensitive fields.

Annex XIII of the Battery Regulation is the clearest worked example of how a Digital Product Passport gates sensitive data while still serving useful public information. It is why the battery passport is widely treated as the reference model for every later DPP.

Why the battery passport matters beyond batteries

The battery passport is the proving ground for the EU's wider Digital Product Passport system. The data architecture, the unique-identifier approach, the QR data carrier, and the tiered-access model are all being reused as the ESPR rolls out passports for other product groups. If you understand the battery passport, you understand the shape of every DPP that follows. We compare the two regimes directly in DPP vs Battery Passport.

How to prepare before February 2027

The binding date is fixed, and the hardest part is the data, not the QR code. A realistic preparation path:

1. Confirm scope - identify which of your products are EV, LMT, or industrial batteries above 2 kWh.
2. Map the data - line up each required field against where the data lives today (your systems, your cell supplier, your raw-material sources).
3. Close the carbon and due-diligence gaps first - these have the longest lead time because they reach deep into the supply chain.
4. Set up dynamic updates - decide how state-of-health and lifecycle events will flow into the passport after sale.
5. Choose a passport platform that can store, verify, gate, and serve the record at scale.

Our live battery passport deadline tracker keeps the key dates in one place as guidance is clarified, and the full battery passport guide walks through the obligations in detail.

Where DPPAutomate fits

DPPAutomate collects the battery data from your systems and suppliers, validates each field against the Regulation (EU) 2023/1542 requirements, enforces the tiered-access model, maintains the verification trail, and generates the QR data carrier and live passport. Dynamic fields like state of health update through the battery's life instead of going stale.
