What Is the EU Battery Passport and Why Should Anyone Care?
By February 2027, every electric vehicle battery sold in Europe must carry a digital record of its entire life. Here is what the regulation actually says, why it exists and what it means for manufacturers, buyers, and the planet.

Somewhere inside the battery pack of the electric car you might buy in 2028 will be a small QR code. Scan it and you will pull up a digital record, the battery passport, telling you where the cobalt in that battery was mined, what its carbon footprint was at manufacture, how many times it has been charged and whether it still holds enough energy for a second life as a home storage unit.
This is not a concept from a sustainability whitepaper. It is a legal requirement. Article 77 of EU Regulation 2023/1542 the EU Battery Regulation mandates that an electronic record accompany every electric vehicle, light transport and large industrial battery placed on the European market. The deadline is 18 February 2027.
To understand why this matters, you first need to understand the problem the regulation is trying to solve.
The battery passport links a physical QR code on the battery to a digital record spanning its entire lifecycle, from raw material sourcing to recycling.
The Problem is Batteries Are Everywhere and Nobody Knows What's in Them
The world is rapidly electrifying. Cars, scooters, grid storage facilities and industrial equipment all run on lithium-ion or comparable battery chemistries. These batteries contain materials like cobalt, lithium, nickel, lead that must be mined, processed, refined and assembled across supply chains that span dozens of countries.
Until now, the person who buys the finished product say, an electric vehicle has had virtually no visibility into that supply chain. They cannot easily know whether the cobalt was sourced responsibly. They cannot compare the carbon footprint of one battery against another. They cannot tell a recycler what is actually inside the pack without sending it to a laboratory. And when a battery reaches the end of its first life, the recycler often has to guess.
Context from EU data: In 2020, only 47% of all portable batteries and accumulators sold in the EU were collected for recycling, according to Eurostat, a stark reminder of how much material is lost when the right information is not available at the right time.
The EU Battery Regulation is designed to fix this by making data travel with the battery, not just accompany a product manual that is immediately lost.
EV batteries draw on raw materials sourced across dozens of countries. The battery passport makes this supply chain visible to buyers, recyclers and regulators.
Where the Battery Regulation Comes From
The regulation did not appear in isolation. It is part of a layered policy architecture that the EU has been building since 2018.
The Legislative Ancestry
2018 — Strategic Action Plan on Batteries Introduced as part of the Clean Mobility Package. Its goal: develop a sustainable and competitive battery value chain in Europe and ensure a reliable and sustainable supply of batteries.
2019 — European Green Deal A comprehensive package of policy initiatives to make the EU climate neutral by 2050, safeguard biodiversity, establish a circular economy, eliminate pollution and boost competitiveness. The battery sector is explicitly named as a priority.
2020 — Circular Economy Action Plan Adopted as a key component of the Green Deal and a prerequisite for achieving the EU's 2050 climate neutrality goal. It promotes sustainable use of resources across the entire lifecycle of products, with resource-intensive sectors like batteries at the centre.
December 2020 — European Commission proposes the Battery Regulation A ground-up replacement for the 2006 Battery Directive, which had become outdated in the face of large format lithium-ion batteries.
July 2023 — EU Regulation 2023/1542 is formally published Replacing Directive 2006/66/EC and entering into force in August 2023.
February 2027 — Battery passport becomes mandatory For EV, LMT and industrial batteries above 2 kWh placed on the EU market.
The regulation explicitly aims to do four things, promote sustainability in production, encourage circularity by making data available for second-life uses, ensure safety by protecting human health and the environment and improve transparency and consumer information.
The Battery Regulation sits within the broader European Green Deal, which targets climate neutrality for the EU by 2050.
What Is a Digital Product Passport and How Does the Battery Passport Fit?
The term "battery passport" is a specific instance of a broader concept, the Digital Product Passport (DPP). The European Commission defines a DPP as "a structured collection of product-related data with predefined scope and agreed data ownership and access rights conveyed through a unique identifier."
In plain language, a DPP is a standardised digital record that follows a product through its entire life from manufacture to recycling and is accessible to different actors in the supply chain depending on their role and access rights.
The battery passport is the first digital product passport introduced in Europe and globally, with further product categories to follow.
After batteries, DPPs are planned for textiles, construction materials, consumer electronics, plastics, chemicals and the broader automotive sector. The battery passport is, in effect, the prototype from which the entire EU digital product passport system will be built.
Global picture: The EU is not alone. Canada is considering a battery passport for EVs to enforce ESG standards. Japan is moving to mandate disclosure of EV battery production emissions. China has launched development of its own digital battery passport. India has identified battery passports as an opportunity and international standardisation activities are underway in Brazil, Indonesia, South Korea, Australia and Chile. The EU's approach is the most legally binding to date.
Which Batteries Are in Scope? The Three Categories That Matter
Article 77(1) of the Battery Regulation is precise about which batteries must carry a passport. Not all batteries are included — portable batteries (AA, AAA, button cells) and starter batteries (SLI — starter, lighting, ignition) are outside the scope of the passport requirement. The three categories that are in scope are:
| Category | Definition | Examples | Weight threshold |
|---|---|---|---|
| Electric Vehicle (EV) Battery | Provides electric power for traction in hybrid or electric vehicles of categories M, N or O (EU 2018/858), or category L if above 25 kg | Passenger cars, buses, trucks, category L vehicles above 25 kg | > 25 kg for category L |
| Light Means of Transport (LMT) Battery | Powers wheeled vehicles that can run on the electric motor alone or in combination with human power; type-approved as category L | E-bikes, e-scooters, e-mopeds | ≤ 25 kg |
| Industrial Battery (if > 2 kWh) | Designed for industrial uses — or any battery above 5 kg that is not LMT, EV, or SLI — including stationary energy storage systems | Grid storage, forklifts, hospital UPS, railway traction, data centre backup, home storage above 2 kWh | > 5 kg (passport only if > 2 kWh) |
One important nuance: within the industrial battery category, only those with a capacity greater than 2 kWh fall under the battery passport requirement. A small industrial battery below that threshold is exempt from the passport, though other parts of the regulation still apply to it.
Worth noting: The regulation covers batteries placed on the EU market, which includes batteries imported into the EU, not just those manufactured in Europe. A battery pack assembled in South Korea and installed in a German electric car is subject to the same passport requirements as one built in Germany.
Who Is Responsible for Creating the Battery Passport?
The regulation places responsibility on the economic operator placing the battery on the market or putting it into service. In practice, this is either the manufacturer or the importer.
The regulation defines manufacturer as any natural or legal person who manufactures a battery, or who has a battery designed or manufactured and markets it under their own name or trademark, or puts it into service for their own purposes. An importer is a person or entity established within the EU who places a battery on the market from a third country.
To use the most common real-world example: if a European automaker buys battery cells from a Korean supplier, assembles them into a battery pack, and installs that pack in a car they sell to European consumers under their own brand, the automaker is the manufacturer and is therefore responsible for the battery passport.
The regulation allows the economic operator to authorise another operator to act on their behalf. Core responsibilities include:
- Creating the passport , attributing a unique identifier linked to a QR code that marks the battery.
- Keeping it accurate, ensuring the information in the battery passport is accurate, complete, and up to date.
- Storing the data , maintaining the data included in the passport throughout the battery's life, including after transfer of responsibility.
There are two specific situations in which responsibility for the passport transfers, when a battery has been subject to preparation for reuse, repurposing, or remanufacturing and must be placed on the market anew; and when a battery's status changes to "waste," at which point a producer, producer responsibility organisation, or waste management operator becomes responsible.
What the Passport Actually Contains: The Seven Content Clusters
The mandatory data attributes are defined in Article 77 and Annex XIII of the regulation. For EV batteries alone, Annex XIII outlines around 80 mandatory data attributes, organised across seven content clusters:
1. General Battery and Manufacturer Information
Unique battery passport identifier, unique battery identifier, responsible economic operator identifier, manufacturer information, manufacturing place, manufacturing date, battery category, battery weight, and battery status (original, repurposed, reused, remanufactured, or waste). All of this information is publicly accessible.
2. Carbon Footprint
The declared carbon footprint per functional unit, broken down by lifecycle stage (raw material acquisition and pre-processing, manufacturing, distribution, and end-of-life recycling). Also includes the carbon footprint performance class and a weblink to the public carbon footprint study. This is the first time the EU has made carbon footprint reporting mandatory for a product category.
3. Supply Chain Due Diligence
The information indicated in the annual due diligence report, covering the economic operator's management system, risk management obligations and third-party verification. This report is publicly accessible via the battery passport, typically as a PDF link.
4. Battery Materials and Composition
Battery chemistry (general description of cathode, anode, and electrolyte), critical raw materials present above 0.1% weight-by-weight, and for persons with a legitimate interest detailed composition including materials used in cathode, anode, and electrolyte, CAS numbers, and mass fractions.
5. Circularity and Resource Efficiency
Recycled content shares of cobalt, lithium, nickel, and lead; renewable content share; dismantling information (manuals for battery removal and pack disassembly); part numbers for components and spare part suppliers; and end-of-life guidance for consumers.
6. Performance and Durability
Approximately 40 data attributes covering rated capacity, voltage, power capability, round-trip energy efficiency, internal resistance, expected lifetime in cycles and calendar years, temperature conditions and records of negative events (deep discharge, overcharge, accidents).
7. Hazardous Substances
List of hazardous substances above 0.1% weight-by-weight (other than mercury, cadmium, and lead, which have their own labelling requirements), their hazard classes, CAS numbers, location within the battery, and their impact on environment, human health and safety of persons.
The battery passport makes recycling more efficient by giving recyclers immediate access to composition data, eliminating costly manual sampling of each pack.
Why This Matters Beyond Compliance
Regulations require compliance, but the battery passport is designed to unlock value that goes well beyond ticking boxes. The data it generates creates what economists call information symmetry, the same facts being available to all relevant parties rather than sitting in one company's ERP system.
Consider what changes when this data is available. A recycler receiving a used EV battery currently spends significant effort and cost sampling and testing the pack to understand what is inside it. With a battery passport, the detailed composition data, the cathode chemistry, the hazardous substances, the mass fractions of each material, is accessible immediately, reducing sampling effort and optimising the dismantling process.
A second-hand vehicle buyer gains access to performance and durability data, remaining capacity, number of full charge-discharge cycles completed, making the residual value of the battery genuinely calculable rather than a rough estimate.
A logistics company transporting used batteries gains access to accident history and hazardous substance data, enabling a precise risk categorisation for transport, reducing the chance of applying insufficient safety precautions to a battery that has been in an accident.
And a policymaker gains, for the first time, accurate data on the battery stock at each lifecycle stage enabling evidence-based decisions on recycling targets, raw material strategy and infrastructure investment.
