The agreement was signed in Beijing during the visit of German Chancellor Friedrich Merz to China, accompanied by a high-level German business delegation.
Under the MoU, CATL and BMW will jointly undertake pilot projects focused on cross-border data transfer within the Battery Passport framework.

CATL and BMW have maintained a strategic partnership since 2012, working together on battery production, joint research and development, and sustainable supply chain initiatives. The new MoU expands the partnership beyond product-level cooperation to broader institutional coordination, underscoring a shared commitment to advancing electric mobility.
Through enhanced transparency and harmonized carbon accounting approaches, both companies aim to strengthen trust across the value chain and contribute to building a more resilient global automotive ecosystem.
CATL stated it will continue to pursue open cooperation with international partners, leveraging technological innovation to accelerate the global green transition and support a sustainable future for the automotive sector.
