EU Battery Regulation (Regulation (EU) 2023/1542)

The EU Batteries Regulation (Regulation (EU) 2023/1542) is a directly applicable legal act of the European Union governing the entire life cycle of batteries – from raw material extraction, design and manufacture through use, reuse and recycling – and replacing the former Batteries Directive 2006/66/EC.

Definition

Regulation (EU) 2023/1542 is a binding EU legal instrument laying down product and process requirements for all types of batteries placed on the EU market or put into service. It covers sustainability, safety, labelling, information provision, extended producer responsibility, collection, treatment and reporting on waste batteries.

In manufacturing, it transforms batteries from mere components into highly documented “digital products” and serves as:

• a horizontal product-law framework for batteries as stand-alone products and as components of machinery, vehicles, devices and stationary energy storage systems
• a compliance driver for design, material selection, supply chains, production processes, quality assurance, take-back and recycling structures, and data management

Legal status and timeline

• Adopted: 12 July 2023
• Published in the Official Journal: 28 July 2023
• Entered into force: 17 August 2023
• Generally applicable as directly applicable law: since 18 February 2024, with phased application of individual provisions

Scope – battery categories

The Regulation applies to all batteries placed on the EU market or put into service:

• Portable batteries (consumer devices, tools, household appliances)
• Light means of transport (LMT) batteries (e.g. e-bikes, e-scooters)
• Industrial batteries (stationary storage, UPS systems, machinery, robotics and process plants)
• Electric vehicle (EV) batteries
• SLI batteries (starting, lighting and ignition)

Key technical terms

• Battery: A device delivering electrical energy by the direct conversion of chemical energy, comprising one or more non-rechargeable or rechargeable battery cells, modules or packs. This includes batteries prepared for reuse, repurposed or remanufactured.
• Battery cell: The basic functional unit (electrochemical cell).
• Battery module: A set of battery cells connected together or encapsulated within a housing.
• Battery pack: A group of electrically connected cells or modules, or cells or modules enclosed in a housing, forming a complete unit.

These definitions are important for product architectures (cell → module → pack → system), conformity assessment and labelling at each level, and documentation obligations (environmental, safety and performance data).

Core requirements (technical focus areas)

Carbon footprint – Article 7

For EV batteries, LMT batteries and rechargeable industrial batteries (> 2 kWh), evidence requirements are introduced in stages:

1. Declaration: Carbon footprint declaration for each battery model and manufacturing plant
2. Performance classes: Classification into carbon footprint performance classes based on emissions
3. Thresholds: Maximum life-cycle carbon footprint thresholds based on life cycle assessment (LCA)

Recycled content and circular economy – Article 8

New batteries (particularly industrial and EV batteries) must meet phased minimum recycled-content requirements:

• Relevant raw materials: cobalt, lead, lithium, nickel
• Progressively increasing percentages (e.g. lithium: 6% from 2031 and 12% from 2036, subject to the applicable legal provisions)

Performance, durability and safety

• Requirements for cycle endurance, capacity retention, and charging/discharging profiles
• Electrical, mechanical and thermal safety
• Protection against misuse, short circuits, overcharging and overdischarging
• Minimisation of fire and explosion risks

Digital battery passport – Articles 77 and 78

From 18 February 2027, a digital battery passport is mandatory for LMT and EV batteries and industrial batteries (> 2 kWh), accessible via a QR code:

• Technical data sheets and performance parameters
• Information on composition and recycled content
• State-of-health (SoH) data and expected service life
• Information on provenance and due diligence

Removability and replaceability – Article 11

Portable batteries incorporated into products must be designed to be readily removable and replaceable by end users or independent professionals using commercially available tools, subject to the Regulation’s specific provisions and exceptions (design for repair).

Supply-chain due diligence – Article 48

In-scope economic operators must establish risk-management and due-diligence policies to identify and mitigate social and environmental risks related to sourcing lithium, graphite, cobalt and nickel. Updated legal date: Regulation (EU) 2025/1561 postponed the application of these obligations to 18 August 2027; applicable exemptions and thresholds must be assessed separately.

Extended producer responsibility (EPR)

• Obligation to organise or finance collection and take-back systems
• Binding targets for recycling and material recovery, alongside rules on reuse and repurposing
• Reporting obligations to authorities (material flows, recycling efficiency and recycled content)

Practical application in manufacturing

Product development and design

• Material selection: Consideration of rules on hazardous substances, critical raw materials and recycled content; optimisation of chemistries (Li-ion, LFP, NMC) for service life and recyclability
• Design for safety and circularity: Modular pack designs for disassembly, mechanical protection (crash structures, enclosures) and integrated battery management systems (BMS)
• Design for repair: Avoiding permanent adhesive joints and favouring mechanical connections

Production processes

• Quality-assured cell production (electrode coating, formation)
• Traceable module and pack assembly (serial numbers, batch tracking)
• In-line inspection and end-of-line testing: Safety and performance tests in accordance with the Regulation and relevant standards (EN, IEC)
• Monitoring of resource consumption and emissions, and optimisation of scrap rates

Conformity assessment and documentation

• Batteries must undergo the relevant conformity-assessment procedure and bear {ce-konform|CE marking} where required
• Preparation of comprehensive technical documentation (in accordance with Annex VIII) demonstrating compliance with safety and sustainability requirements

Supply chain management

• Transparency regarding the origin of critical raw materials and mining conditions
• Obtaining detailed material data from upstream suppliers (material compliance)
• Integrating due-diligence strategies into supplier assessment

Data management and IT architecture

• Building the IT infrastructure to populate the digital battery passport
• Interfaces between ERP systems, manufacturing execution systems (MES) and the central EU registry
• Serialisation and traceability throughout the value chain

System integration (machinery, vehicles, installations)

• Ensuring integrated batteries comply with the Regulation (labelling, safety, sustainability)
• Alignment with other product legislation (Machinery Directive, EMC Directive, Low Voltage Directive)
• Taking second-life scenarios into account (e.g. repurposing EV batteries for stationary energy storage)

Take-back, recycling and second life

• Developing take-back systems (collection points, logistics, sorting by chemistry/category)
• Working with recycling companies to ensure recovery targets are met
• Legally compliant repurposing, including any required new conformity assessment and labelling

Key deadlines for industry (roadmap)

Significance for technical roles

• Product developers / design engineers: Integrating regulatory requirements into specifications for cells, modules, packs and systems
• Production planners / manufacturing engineers: Implementing compliant production processes, testing concepts and traceability
• HSE and environmental managers: Coordinating circular-economy activities, recycling, reporting and due diligence
• Regulatory and compliance specialists: Interpreting articles and technical annexes and translating them into internal guidelines
• IT and data architects: Developing the digital infrastructure for battery passports and traceability
