Blockchain technology is increasingly embedded in the automotive sector as a trusted digital system for tracking vehicle data and permissions. As per Coinbase, about 60% of Fortune 500 companies are pursuing blockchain initiatives, reflecting broad enterprise interest. In the car industry, blockchain supports digital battery passports that record the lifecycle of EV batteries and enable provenance across the supply chain, from mining to recycling, while ensuring data immutability. EV battery passports are becoming mandatory in the EU by 2027, driving adoption across automakers and suppliers.
A modern EV battery spans mining, refining, cell manufacturing, pack assembly, recycling, and logistics, making a single definitive record valuable. A blockchain-based distributed ledger can serve as the shared source of truth for origins, recycled content, and carbon footprints across multiple companies. Examples illustrate this trend: Volvo Cars launched the world’s first EV battery passport for the EX90 in June 2024, Tesla tracks cobalt provenance with blockchain, and Porsche piloted a blockchain-based digital passport for classics. Regulators and agencies are also leveraging blockchain, such as the California DMV digitizing 42 million car titles in 2024.
Toyota’s Blockchain Lab has explored secure vehicle identities and a Mobility Orchestration Network to link fleets with regulators, while initiatives like Woven City show blockchain-enabled urban mobility. BMW uses JPMorgan’s blockchain to automate international transactions. Sony Honda Afeela envisions an on-chain mobility platform with token incentives. Nissan proposes the Nissan Passport, a digital certificate expanding access based on user actions.
