This thesis investigates the evolving landscape of high-voltage batteries (HVBs) in the high-performance car sector, with a particular focus on the intersection of regulatory compliance, safety, and sustainability. The work is structured in two distinct parts, each addressing critical aspects of the current and future challenges faced by the industry. The first part provides a comprehensive analysis of the global regulatory framework governing HVBs, with special attention to international safety standards and the recently enacted European Regulation (EU) 2023/1542. This regulation represents a significant milestone, as it is the first to address the entire lifecycle of batteries, imposing stringent requirements on sustainability, traceability, recycled content, labeling, and end-of-life management.
