BMW selected Samsung SDI as a supplier of sixth-generation (Gen6) high-voltage battery cells for its next-generation electric vehicles. The German automaker will source the cells from Samsung SDI’s European production base.
The agreement expands BMW’s battery supply network as automakers seek greater control over critical components. BMW said the move supports its strategy of producing battery cells closer to the markets where it builds vehicles.
BMW’s decision reflects a broader industry shift toward regionalized supply chains. By sourcing cells in Europe, the company can reduce dependence on long-distance shipments and limit exposure to trade and logistics disruptions.
The partnership also gives BMW access to additional manufacturing capacity as it scales electric vehicle output. Samsung SDI is preparing to produce large-format cylindrical cells at its facility in Hungary.
Reports indicate that the cells will use a 46 mm cylindrical format. Samsung SDI is expected to begin mass production around 2028, aligning the supply timeline with BMW’s next-generation EV rollout. Samsung SDI will supply cells for BMW vehicles manufactured in Europe. LG Energy Solution will serve BMW’s production footprint in the United States under a parallel agreement. Both companies join BMW’s existing supplier base for next-generation battery cells.
The Gen6 cells will support BMW’s Neue Klasse platform, the company’s next major electric vehicle architecture. The platform is central to BMW’s plan to expand its electric line-up and improve the performance, efficiency and charging capability of future models.
BMW positioned Gen6 batteries as a key part of its electrification roadmap. The new cells are expected to deliver higher energy density and improved charging performance compared with earlier generations.
The company did not disclose the value of the agreement or the volume of cells it plans to purchase. It also did not specify which Neue Klasse models will use Samsung SDI cells.
