EU Battery Regulations Explained: Mandatory Digital Passport by February 2027 

The environmental impact of batteries is a major area of concern, from manufacturing to their disposal, especially with the recent development of Electric Vehicles (EVs) and the devices segment globally. The EU battery regulations is a significant step towards reducing carbon emissions by tracking sustainable practices throughout the battery lifecycle.

It is a set of rules that mandates the industries involved in battery manufacturing, trading, or recycling to implement environmentally friendly practices and support the circular economy. The initiative aims to ensure responsible battery production and its management throughout its lifecycle. It also focuses on tackling the release of hazardous materials from batteries and improving battery recycling rates.

This initiative has also encouraged other countries to adopt the same model, the effect of which will be seen significantly by 2030. Explore the details of the EU Battery Regulation and the role of organisations in battery traceability. 

EU Battery Regulations 2023/1542 Compliance Guide: What You Must Know

Since the implementation of EU regulations in 2023, companies and regulatory bodies have started to rethink and prepare for battery production, use, reuse, recycling, and safe disposal. Here is the timeline that the manufacturers and regulators need to consider: 

Digital Battery Passport Content: What Must it Include? 

The participants across the battery lifecycle must clearly know what data these battery passports must include mandatorily. Here is an overview- 

• Manufacturers’ Information: It must contain the manufacturer’s identity and location information. 
• Battery Features: Must define battery type, its capacity, voltage, and details on its chemical composition. 
• Source or Origin: It must include the source and origin of raw materials, such as nickel, lithium, cobalt, and more.
• Carbon Footprint Data: The carbon release across the battery lifecycle from manufacturing to recycling must be traced and recorded. 
• Battery Recycling Content: The recycling process, which includes the extraction of useful materials, must be tracked and documented. 
• Performance Level of Battery: Durability, capacity, and power delivery of the battery should be tracked throughout the lifecycle.
• Battery Health: State of Health (SoH) of the battery must be documented that can be further used to make decisions on repair and repurpose. 
• Access Control: Each stage of the battery lifecycle runs on its own infrastructure and systems with restricted access rights. Hence, all control mechanisms, intellectual property (IP), and other safety mechanisms applied must be documented to maintain transparency. 

These data must be updated regularly to access accurate information. 

Mandatory Digital Battery Passport Data Organisations Need to Track 

The battery data is broadly categorized into-

• Static Data: Collect and segregate data that is readily available to the public 
• Dynamic Data: Specific information associated with each battery and available only to authorized stakeholders

Chain of Custody for Traceability Across the Supply Chain 

A detailed chain-of-custody record of the battery is required to trace the raw materials, such as lithium, nickel, cobalt, and graphite. Long-term record helps verify the ethical sourcing and practices throughout the battery lifecycle.  

Data to Determine Battery Health 

The new regulatory standards aim to analyse the efficiency and durability of batteries. The manufacturers need to release relevant data, recorded in the battery passport, over time. to determine-

• The state of health of the battery 
• Chemistry and electrochemical performance 
• Expected lifetime 

Environmental and Social Due Diligence

As per EU regulation, starting from August 18th, 2025, companies selling batteries in the EU market must mandatorily conduct a supply chain due diligence. Specific attention is required to track data of high-risk materials such as lithium, nickel, and cobalt 

The audit companies need to generate annual reports on data collected from suppliers to assess risks. It will help authorities address environmental impacts and human health risks. 

Carbon Footprint Data Declarations 

Following the February 2025 EU guidelines, manufacturers must release the carbon footprint of each battery. It must cover the entire battery lifecycle from raw material extraction to distribution to its recycling or disposal, as per the EU Product Environmental Footprint Category Rules (PEFCR). 

Minimum Recycled Content Targets 

Minimum Recycled Content Targets in the EU will apply by 2030–2035. It aims to ensure that a fixed percentage of materials used in batteries comes from recycled sources. The companies must prove it by sharing documented data. 

The EU Regulation 2023/1542 highlights the requirements for recyclers to extract valuable materials from waste batteries efficiently. 

The commission is required to define methodologies to calculate and verify rates of recycling efficiency and recovery of materials. It also defines the format of documentation recorded in the Digital Battery Passport (DBP). 

Digital Battery Passport Architecture Explained: Technology Stack Necessary for Battery Traceability

The technical standard stack represents the minimum required technical standards to implement battery product passports. 

IT Infrastructure- The Foundation Layer

It is the combination of hardware and apt environment to run everything. It includes- 

• Cloud platforms, storage systems, and servers 
• Networking systems
• Databases

A strong IT infrastructure will enable companies to–

• Securely store and share data 
• Enable easy scalability of the system
• Ensure real-time tracking

Distributed Software Functions- The Application Layer 

It includes the logic and applications that run across distributed systems. It includes –

• Battery passport platforms
• APIs for the exchange of data 
• Blockchain and distributed ledger technology 
• Data analysis and processing tools 

Management Systems- The Control Layer

This interface monitors and controls the entire digital battery passport ecosystem. It can be categorised into-

• Database management systems
• Quality control systems
• Battery lifecycle tracking system 
• Analysis and reporting dashboard
• Regulatory and compliance 

The management system is essential to ensure that the data is accurate and updated. Stakeholders can generate and analyse reports for regulations. 

Governance Systems: Accountability Layer 

This layer consists of rules and policies to hold all participants and stakeholders accountable for their activities. It defines who-

• Owns Data
• Access Rights 
• Update Rights 

To ensure this, the system – 

• Defines data access and edit policies 
• Suggests compliance frameworks 
• Sets Audit mechanisms

Governance systems are essential to prevent data misuse and build trust among stakeholders. 

Blockchain for Battery Supply Chain Traceability

In the case of a battery product passport, different stakeholders such as Original Equipment Manufacturers (OEMs), suppliers, and recyclers run separate systems, but they are interoperable. A distributed system helps avoid central dependency and enables real-time traceability. 

Blockchain and DTL are the most effective solutions to maintain an immutable and verified record of all data that can be traced back for auditing records and transactions.

Blockchain for Battery Supply Chain Management

Maintaining data transparency across the complex battery supply chain isn’t easy or guaranteed. Hence, there is a need for strong technology and blockchain infrastructure, to- 

• Maintain an immutable record of all data across the battery life cycle 
• Access Real-time shareable data across a distributed system
• Use a verifiable record of data stored on the distributed ledger 
• Ensure data interoperability 
• Support auditing to trace historic data stored on the blockchain network
• As data once stored on the blockchain platform cannot be edited, it holds all participants across the battery ecosystem accountable for their actions. 

As battery regulations tighten with the upcoming 2027 deadline, especially in the EU, manufacturers and enterprises need to build secure, transparent, and interoperable digital systems. This is where a blockchain development company can deliver real and impactful value.
