A Standardized Data Model for the Battery Passport: Paving the Way for Sustainable Battery Management

The green energy revolution has propelled the use of batteries, necessitating holistic lifecycle monitoring and data sharing among stakeholders involved in the supply chain and in the whole lifecycle. The European Union mandates digital passports through the Battery Regulation (EU) 2023/1542. Recognizing the challenges in today's landscape – from fragmented software to limited collaboration and the array of battery types – this paper unveils a standardized battery passport data model aimed at overcoming the challenges posed. It organizes techno-environmental data into a tree structure, ensuring compliance with European regulations and offering a Life Cycle Inventory-ready structure for the purpose of supporting Life Cycle Assessment studies. The future implementation on a centralized platform has the potential to drive eco-friendly battery infrastructure growth.
