Interoperability Challenges of a Digital Product Passport System

The Digital Product Passport (DPP), particularly its pilot digital battery passport, targets new electric vehicle and industrial batteries over 2 kWh. Its rollout across various sectors necessitates a robust technical setup, suitable procedures, and a favorable business environment to address significant challenges such as ensuring interoperability for secure data sharing, aligning with complex legal standards, and meeting a tight deadline for the development of harmonized European Norms (hEN). The DPP system faces notable challenges, including ensuring complete interoperability for secure data exchange among stakeholders, navigating complex legal and business environments to align with multiple regulations, and meeting the tight deadline for developing Harmonized European Norms by December 31, 2025. These hurdles are compounded by the need to integrate existing technical systems and accommodate future regulations and technological advances.
