Batteries have become high value, data rich assets that need to be tracked throughout increasingly complex global supply chains. The rapid growth of electric vehicles, battery energy storage systems (BESS), and other battery powered applications has created new challenges around battery traceability, sustainability, and lifecycle management. Unlike most electrical and mechanical components in electronic devices, batteries contain critical raw materials often including lithium, cobalt, and nickel, whose sourcing, environmental impact, use, and end of life treatment are under increasing scrutiny.
At the same time, battery supply chains have become highly globalised and fragmented, involving multiple actors including miners, refiners, cell manufacturers, pack assemblers, OEMs, fleet operators, second life providers, and recyclers. As the ownership of batteries changes throughout their lifecycle, stakeholders need a reliable mechanism to access information about a battery's origin, composition, health, and usage history. Battery Passports address this challenge and enable transparency, traceability, and informed decision making across the battery value chain.
The blog discusses the growing importance of Battery Passports, the role of connectivity and other enabling technologies in Battery Management Systems and industry use cases involving Battery Passports. If you’re interested to find out more, recently Transforma Insights has published a report titled ‘Connected Batteries: 268 million battery devices by 2035 supporting grid modernisation and clean energy systems’. This report focuses on battery technologies used in grid-scale, portable batteries and battery energy storage systems (BESS). The analysis focusses on industrial scale batteries deployed for electricity storage, grid balancing, and renewable energy integration. Information and market analysis for automotive batteries can be found in our report titled ‘Automotive Batteries: An EV charging alternative worth USD3 billion in 2034’.
A Battery Passport is a digital record that accompanies a battery throughout its lifecycle, providing details on its origin, composition, performance, usage history, and end of life management. Rather than being a static document, a Battery Passport combines information from manufacturing systems, Battery Management Systems (BMS), IoT platforms, and cloud analytics to create continuously updated digital information for each battery. Battery Passports are being introduced to create a secure digital profile of a battery's origin, composition, performance, and lifecycle history. Manufacturers, service providers and even in some cases consumers can now track charge and discharge cycles of batteries, battery health, temperature history, remaining useful life and degradation patterns, maintenance and safety events.
Battery Passports rely on continuous data collection, management, and exchange across multiple stakeholders throughout the battery lifecycle. As a result, technology and service providers play a critical role in enabling Battery Passports by connecting Battery Management Systems (BMS), IoT platforms, cloud analytics, and supply chain data sources into a unified digital framework.
Bosch, for example, has a ‘Battery in the Cloud’ platform, combining manufacturing information (origin, composition, production data) with real time telemetry such as battery usage, state of health, and service life data. The platform continuously analyses battery performance to support predictive maintenance, end of life decisions, resale assessments, and second life battery applications. Similarly, Siemens provides a Battery Passport platform that aggregates battery lifecycle data from suppliers, manufacturers, and operators into a single digital record. Through APIs and using the Catena-X data ecosystem, the solution enables supply chain traceability, battery tracking, automated passport creation, and data sharing to support circular economy and battery lifecycle management initiatives.
By providing the digital infrastructure, connectivity, and analytics required to manage battery data at scale, technology providers are helping organisations unlock greater value from batteries throughout their lifecycle. The graphic below depicts a 3-T framework encompassing Transparency, Traceability and Trust. While not an industry standard framework, it is derived from key objectives commonly cited in battery passport regulations, industry initiatives, and sustainability programs. The framework highlights how battery passports providers create value across these three dimensions while illustrating that many companies span multiple areas and where their Battery Passport initiatives create the most value. The three elements are defined as follows:
Regulatory and data governance considerations are becoming increasingly important as the European Union makes digital Battery Passports mandatory for all EV and industrial batteries over 2kWH by February 2027. Similar initiatives are emerging globally, with jurisdictions such as California exploring battery traceability and supply chain transparency requirements. As regulatory expectations evolve, manufacturers, battery suppliers, asset owners, and technology providers must ensure that battery data can be collected, standardised, verified, and securely shared across increasingly complex ecosystems. These requirements are accelerating investment in digital platforms, connectivity solutions, and data management capabilities that support Battery Passport implementation.
Beyond regulatory compliance, several operational challenges remain. Battery Passports require the integration of data from multiple stakeholders, including raw material suppliers, cell manufacturers, OEMs, fleet operators, and recyclers. Ensuring interoperability across different BMS platforms, IoT platforms, and data standards can be complex and costly. In addition, concerns around data ownership, cybersecurity, intellectual property protection, and cross border data sharing may limit stakeholders' willingness to exchange information. Establishing trusted frameworks for secure data sharing while maintaining data sovereignty will therefore be critical to large scale adoption.
Furthermore, maintaining accurate and up-to-date battery records throughout the asset lifecycle requires reliable connectivity, robust data quality controls, and scalable digital infrastructure. Organisations must balance transparency requirements with commercial sensitivities, particularly when sharing operational and supply chain information across multiple partners.
Energy transition cannot be powered by a single technology. It requires an ecosystem of connected solutions spanning renewable energy, electric mobility, energy storage, and digital infrastructure. As batteries become increasingly central to this transition, Battery Passports have the potential to serve as a foundational digital layer that connects stakeholders across the battery value chain.
Beyond supporting transparency and traceability, Battery Passports can unlock significant business value through improved asset management, predictive maintenance, second life battery deployment, and more efficient recycling processes. Looking ahead, advances in AI, digital twins, distributed ledger (or blockchain), and connected battery platforms are expected to further enhance Battery Passport capabilities. These technologies could enable real time battery health assessments, automated lifecycle reporting, dynamic carbon footprint tracking, and trusted data sharing across global supply chains. As the battery ecosystem matures, Battery Passports are likely to evolve from compliance tools into strategic enablers of circular economy initiatives, sustainable supply chains, and intelligent battery lifecycle management.
Ultimately, the long-term value of Battery Passports lies not only in documenting a battery's history but also in creating a trusted digital identity that helps maximise performance, extend asset life, and support a more sustainable and resilient energy ecosystem.
