At the end of February 2026, CATL and BMW signed a Memorandum of Understanding in Beijing. As part of this, both companies have agreed on pilot projects for trustworthy data exchange and decarbonization along the entire supply chain for traction batteries.

BMW and CATL are relying on Catena-X for their project. Thanks to the standardized automotive data ecosystem, the pilot projects aim to support the alignment of technical standards, promote coherent and science-based policy frameworks and strengthen the long-term stability of the industry. By exploring possible applications for the battery passport, both companies are implementing new compliance practices in China and the EU. Together, they aim to drive the broad adoption of global standards for battery information and data.

Many Years of Cooperation

The Chinese battery manufacturer and the German car manufacturer have been partners since 2012. The cooperation includes the areas of battery production, joint research and development and sustainable supply chains. The new memorandum of understanding expands the partnership from cooperation at product level to more comprehensive institutional coordination and reaffirms the joint commitment to promoting electromobility.

Through intensive cooperation in the areas of products and supply chains, both companies expect to improve their digital management and exchange capacities and, as a result, comply with EU market access regulations. (se)
