Towards more sustainable EV batteries through transparency and data analysisSUPPLIER AND ENGINEERING QUALITY | CASE STUDY Volvo cars Challenge Solution Impact Volvo Cars sought greater transparency and traceability across EV battery supply chains to strengthen supplier engineering oversight, quality assurance, sustainability and go beyond regulatory compliance.Volvo Cars, working with Circulor, implemented a digital battery passport using private permissioned blockchain, configurable data verification and machine learning. The solution connected millions of supply-chain data points, enabled immutable traceability of critical raw materials, verified carbon footprint and recycled content and detected anomalies. The passport was first launched with the EX90 and embedded into production systems.The digital battery passport strengthened transparency, trust and governance across Volvo Cars’ EV battery supply chain by embedding verified data into core production processes and scaling up traceability globally, enabling: –End-to-end traceability of critical raw materials across electrified vehicles. –Verified carbon footprint and recycled content at scale. –Improved supplier oversight, quality governance and stakeholder transparency.
