Battery traceability is rapidly becoming a global priority. As electric vehicles, energy storage systems, and battery-powered devices scale worldwide, governments are introducing stricter rules around transparency, sustainability and supply chain accountability.
At the centre of this shift is the Digital Battery Passport (DBP). While the European Union has taken the lead with a legally mandated framework under Regulation (EU) 2023/1542, other major markets such as China and the United States are developing their own battery traceability approaches.
This growing international movement is creating what many industry observers now describe as a global “battery passport race”. The challenge is no longer whether battery traceability will become standard, but how different regions will shape and align their systems.
Why Battery Traceability Has Become a Global Priority
Battery supply chains are increasingly complex, spanning multiple nations or even continents. Critical raw materials such as lithium, nickel, cobalt and graphite often move across multiple countries before a battery reaches the market.
As governments push for cleaner transport and stronger industrial resilience, there is growing pressure to improve visibility across these supply chains. Battery traceability now supports several major objectives, including carbon footprint reporting, ethical sourcing verification, circular economy compliance, recycling and material recovery tracking, product safety monitoring, supply chain resilience, and ESG reporting.
According to the International Energy Agency (IEA), global electric car sales exceeded 14 million units in 2023, while battery demand continues to grow rapidly. China currently accounts for a major share of global battery manufacturing capacity, while Europe and the United States are investing heavily in domestic battery ecosystems.
As battery demand increases, so does the need for reliable and interoperable lifecycle data.
The EU’s Digital Battery Passport Framework
The European Union currently has the most comprehensive and clearly defined battery passport framework, Regulation (EU) 2023/1542.
Under the regulation, certain categories of batteries placed on the EU market will require a Digital Battery Passport from February 2027 onwards. The regulation applies particularly to industrial batteries above 2 kWh, electric vehicle batteries, and light means of transport batteries.
The EU framework places strong emphasis on lifecycle transparency and circular economy objectives. Required data categories include carbon footprint information, recycled content disclosure, battery chemistry and composition, durability and performance metrics, supply chain traceability, and end-of-life handling information.
The passport must be accessible digitally and structured in a machine-readable format. This supports interoperability across the battery value chain.
TheEuropean Commission’s Batteries Regulation Overview explains that the regulation aims to improve sustainability, strengthen recycling systems, and reduce environmental impact across the battery value chain.
One of the EU’s strongest advantages is regulatory clarity. Companies already know that compliance requirements are coming, allowing businesses to begin preparing data systems, supplier coordination mechanisms, and lifecycle traceability infrastructure in advance.
China’s Expanding Battery Traceability Ecosystem
China has developed one of the world’s largest battery manufacturing ecosystems and has simultaneously built extensive battery traceability mechanisms, particularly within the electric vehicle sector.
The Chinese government introduced national battery traceability requirements several years ago, focusing heavily on battery recycling management, industrial coordination, and resource security. According to the State Council of the People’s Republic of China, manufacturers, vehicle producers, and recycling actors are required to participate in traceability systems designed to monitor battery movement and end-of-life handling.
China’s approach differs from the EU model in several important ways. While the EU strongly emphasises sustainability disclosure and consumer-facing transparency, China’s framework focuses more heavily on industrial oversight, manufacturing coordination, and material recovery management. Battery traceability is closely integrated with broader industrial policy objectives and national resource management strategies.
China’s battery ecosystem also benefits from scale. The country remains one of the world’s dominant lithium-ion battery manufacturing hubs, with significant influence over global supply chains. This means Chinese traceability standards could have substantial international impact, particularly for companies sourcing battery materials or components from Chinese suppliers.
In practice, many global battery manufacturers may eventually need to align with both EU and Chinese traceability expectations simultaneously.
The United States and The Push for Supply Chain Transparency
The United States has taken a somewhat different path. Instead of introducing a single nationwide battery passport regulation, the US approach currently focuses on supply chain resilience, domestic manufacturing and critical mineral transparency.
Policies linked to the Inflation Reduction Act have accelerated interest in battery traceability by tying incentives to sourcing and manufacturing requirements.
In addition, organisations such as the Global Battery Alliance are supporting the development of internationally aligned battery passport concepts that involve stakeholders from multiple regions.
The US landscape remains more fragmented than the EU framework, but momentum around transparency and traceability is growing rapidly.
Key Differences Between EU, China and US Approaches
Although all three regions are moving towards stronger battery transparency, their priorities differ.
The EU focuses heavily on sustainability, circularity and regulatory compliance. Its framework is legally defined and standardised across member states.
China places stronger emphasis on industrial oversight, manufacturing coordination and recycling management. The system is integrated closely with national industrial policy.
The United States is currently driven more by supply chain security, strategic sourcing and domestic manufacturing incentives. Standardisation efforts are still developing.
These differences matter because battery supply chains are global by nature. A battery may contain materials sourced in Africa, processed in China, assembled in Europe, and integrated into vehicles sold in North America
Without interoperability among regional traceability systems, manufacturers could face duplicate reporting obligations, conflicting data requirements, increased compliance costs, fragmented supply chain management, and greater complexity in cross-border audits.
This is why interoperability is emerging as one of the most important issues in the future of Digital Battery Passports.
The Growing Importance of Interoperability
As battery supply chains operate internationally, companies may soon need to comply with multiple traceability frameworks simultaneously. A battery manufactured in one region may be sold, reused or recycled in another.
Without interoperability, businesses could face duplicated reporting requirements, inconsistent data structures and higher compliance costs.
This is why many industry discussions are increasingly focused on:
- Shared data standards
- Common identifiers
- Secure data exchange protocols
- International governance models
The future success of battery passports may depend not only on regulation, but also on how effectively different systems communicate with one another.
What this Means for Manufacturers, Suppliers, and OEMs
For battery manufacturers and supply chain operators, the global passport race creates both opportunities and pressures.
Companies that invest early in structured data management and interoperable systems will likely be better prepared for evolving regulations across markets.
At the same time, businesses will need to manage increasing expectations around transparency, carbon reporting and ethical sourcing verification.
This shift also reinforces the importance of scalable digital infrastructure capable of supporting cross-border traceability and compliance.
How BASE Supports Internationally Interoperable Battery Passports

BASE is developing a trusted and interoperable Digital Battery Passport framework designed to support secure data sharing, lifecycle transparency, circular economy objectives, and cross-border interoperability. Through pilot implementations, research activities, and collaboration across the battery value chain, BASE contributes to building scalable Digital Battery Passport systems capable of adapting to rapidly evolving international requirements.
Our work focuses on enabling practical interoperability while supporting sustainability, traceability, and long-term battery value chain resilience.
Looking Ahead
The global battery passport race is still in its early stages, but its direction is becoming clear. Governments and industries worldwide are moving towards stronger traceability, greater transparency and more structured lifecycle data management.
The European Union currently leads with the most mature regulatory framework, while China and the United States continue to expand their own approaches based on national priorities.
Over time, the biggest challenge may not be creating battery passports, but ensuring that different systems can work together effectively. Organisations that prepare for interoperability today will be better positioned to operate in the future global battery economy.
