On February 25 in Beijing, Contemporary Amperex Technology Co., Limited (CATL) and the BMW Group signed a Memorandum of Understanding (MOU) to enhance their collaboration on pilot projects for battery passports and decarbonization across the power battery supply chain. The signing took place during German Chancellor Friedrich Merz’s visit to China, which included a high-level German business delegation.
Under this agreement, CATL and BMW will jointly develop pilot initiatives focused on cross-border data transfer within the battery passport framework. The partners will work on trusted data exchange, carbon accounting methodologies and innovative tools to calculate the full lifecycle carbon footprint of batteries. These efforts will leverage the Catena-X standardized automotive data ecosystem to align technical standards, support coherent, science-driven policy frameworks and foster long-term industrial stability.
By piloting battery passport applications, both companies aim to demonstrate compliance with China-EU regulatory requirements and promote the wider adoption of global battery information and data standards. This initiative is designed to facilitate transparent and secure data sharing across international supply chains, while advancing sustainable practices in battery production and use.
CATL and BMW have maintained a strategic partnership since 2012, collaborating on battery manufacturing, joint research and development, and sustainable supply chain solutions. The new MOU expands this relationship from product-level cooperation to broader institutional coordination, reinforcing their shared commitment to advancing electric mobility through innovation and sustainability.
Through deeper integration of digital management and data exchange capabilities, CATL and BMW plan to strengthen compliance with European Union market access regulations and enhance the low-carbon competitiveness of their products. CATL has reiterated its intention to pursue open cooperation with international partners, using technological innovation to drive the global green transition and support a sustainable future for the automotive sector.
