EU Battery Regulation 2027: What Manufacturers Need to Know

The deadline is fixed

February 18, 2027. That is when the EU Battery Regulation (Regulation EU 2023/1542) begins requiring Digital Battery Passports for industrial batteries with a capacity above 2 kWh and electric vehicle batteries. It is not a soft target. It is not subject to extension based on industry readiness. Products without compliant passports will not enter the EU market.

For battery manufacturers in Japan, South Korea, China, Indonesia, and other major producing countries, this is a regulatory event that affects revenue, not a sustainability initiative to engage with at your own pace.

This guide explains what the regulation requires, which products are affected, what data must be included, and what steps to take in the time remaining.

What the EU Battery Regulation covers

Regulation EU 2023/1542 replaced the old Battery Directive (2006/66/EC). It is significantly more ambitious. It covers:

• Portable batteries (consumer electronics, power tools)
• Industrial batteries (stationary energy storage, forklifts, industrial equipment)
• Electric vehicle batteries (cars, trucks, buses)
• Starter, lighting, and ignition (SLI) batteries (conventional vehicles)

The Digital Battery Passport requirement applies specifically to industrial batteries above 2 kWh and EV batteries. Portable batteries face separate sustainability and labeling requirements but are not subject to the passport requirement under the initial rollout.

The Digital Battery Passport: what it is

A Digital Battery Passport is a structured, machine-readable data record linked to a physical battery via a QR code or NFC tag. It is not a PDF datasheet. It must be:

• Accessible by scanning the data carrier on the battery
• Queryable via a standardized data exchange protocol
• Connected to the EU Central DPP Registry
• Updated with State of Health (SoH) data throughout the battery's operational life

The passport is mandatory before the battery is placed on the EU market. Once in service, it must be updated by whoever operates or maintains the battery.

Required data fields

The regulation specifies over 100 data attributes across multiple categories. Key groups:

Product identification and general data

• Battery manufacturer name, contact, and EU representative
• Manufacturing plant location
• Battery model, batch number, and serial number
• GTIN or equivalent unique identifier
• Date of manufacture
• Expected lifetime (number of cycles, calendar years)

Carbon footprint

• Total carbon footprint per kWh of capacity (kg CO₂e/kWh)
• Carbon footprint by lifecycle stage: raw material extraction, battery component manufacturing, battery assembly, transport
• Carbon footprint performance class (assigned against EU benchmarks once published)
• Carbon footprint study (methodology, third-party verification)

This is the most technically demanding requirement. The carbon calculation must be per-unit and per-manufacturing-plant. If you produce NMC cells in two factories, each factory's output requires separate carbon accounting.

Materials and chemical composition

• Active materials: cathode (chemistry, mass), anode (chemistry, mass), electrolyte
• Critical raw materials: cobalt, lithium, nickel, graphite, manganese (quantity per battery)
• Recycled content: percentage of recycled cobalt, lithium, nickel, and lead (required from 2025/2027 depending on material)

Supply chain due diligence

• Geographic origin of cobalt, lithium, nickel, graphite, and copper
• Due diligence policy and third-party audit information (aligned with OECD Due Diligence Guidance)
• Conflict mineral self-declaration

State of Health (SoH): the dynamic data field

SoH is the only data field that changes after passport creation. It must be updated throughout the battery's operational life. At end-of-life, the final SoH reading is used to determine second-life eligibility and recycling obligations.

The party responsible for updating SoH is whoever operates or maintains the battery: the fleet operator, the grid storage company, the industrial equipment owner.

End-of-life and recycling

• Recycled content percentages (verified)
• Material recovery targets for cobalt, lithium, nickel, copper, lead
• Information for disassembly and recycling
• EU collection point information

Who is responsible?

The "economic operator" placing the battery on the EU market is responsible for the passport. This creates different obligations depending on the supply chain structure:

EU-based battery manufacturers: You create the passport for your own products. Your existing CE marking and technical file processes need to expand significantly.

Non-EU battery manufacturers selling directly to EU customers: You are the responsible party. The passport must exist before the battery ships to the EU.

Importers of batteries from non-EU manufacturers: You are legally responsible if the manufacturer has not provided a compliant passport. This is not negotiable. If your supplier cannot provide a compliant passport, you must create one, or find a different supplier.

EV OEMs sourcing battery cells externally: You are responsible for the vehicle battery passport, which includes data from the cell supplier. This means you must extract compliant data from every cell manufacturer in your supply chain. Cell suppliers who cannot provide structured, standardized data become a compliance liability for the OEM.

The supply chain cascade

The carbon footprint and due diligence requirements create a cascade of data requests up the supply chain.

A battery manufacturer needs carbon footprint data by lifecycle stage. That means they need energy consumption and emissions data from: the mining company extracting cobalt, the refinery processing it, the precursor manufacturer, and their own cell factory.

Each party in the chain will need to provide structured, verifiable data, not a PDF with a number in it. Battery manufacturers who build early relationships with upstream suppliers and implement structured data sharing will complete their passports faster and with lower risk.

For companies in Indonesia's nickel mining sector, this creates both a challenge and an opportunity. Indonesian nickel is a critical feedstock for battery cathodes. Miners who can provide structured, GS1-compliant supply chain data packages will be preferred suppliers for battery manufacturers facing the 2027 deadline.

The GS1 requirement

DPPs require globally unique identifiers. The EU Battery Regulation specifies compliance with GS1 standards, specifically GS1 Digital Link for the data carrier on the physical product.

This means:

1. Register your company with your national GS1 organization

2. Obtain a GLP (Global Location Number) and GTINs for your battery models

3. Generate GS1 Digital Link URIs that encode the battery's identity into the QR code or NFC tag

4. Ensure your DPP system can register these identifiers with the EU Central DPP Registry when it becomes operational

GS1 Indonesia registration is available for Indonesian manufacturers exporting to the EU market.

Timeline for compliance

The February 2025 carbon footprint declaration milestone has already passed. If you are not yet producing carbon declarations, you are already in a compliance gap for the industrial battery market.

Practical steps to take now

Assess your product scope

Map every battery product you sell or plan to sell on the EU market. Determine which fall into the industrial >2 kWh or EV battery categories. For each, list the data you currently have and the data you need to gather.

Begin carbon footprint calculation

Engage a third-party verifier experienced in battery lifecycle assessment (LCA). The ISO 14067 and EU Battery Regulation methodology are the reference frameworks. This process takes 3–6 months for a typical battery product.

Audit your supply chain data

Contact your key material suppliers: cathode precursor, anode, electrolyte, cell component manufacturers. Determine what data they can provide and in what format. Identify gaps early.

Register with GS1

If you have not yet registered, do so now. GS1 registration and GTIN assignment takes days to weeks, not months, but it is a prerequisite for everything else.

Choose a DPP platform

You need software that can store your product data, generate standardized battery passports, connect to physical products via QR/NFC, and submit to the EU registry. Evaluate platforms now. Implementations that start six months before the deadline will fail. The carbon data collection and supply chain coordination take far longer than the software setup.
