BMW Group has nominated Samsung SDI for Europe and LG Energy Solution (LGES) for the United States as additional cell suppliers for its sixth-generation (Gen6) high-voltage batteries, with deliveries from both manufacturers' existing regional plants starting in the late 2020s. No contract volumes, durations or financial terms were disclosed — a gap worth noting in a deal framed as strategic.

The appointments extend BMW's supplier roster for European-produced cells to three names: CATL, EVE Energy and Samsung SDI. LGES will supply cells for the US market. The company presented the move as an application of its "local for local" principle, under which components are sourced close to vehicle assembly sites wherever possible.

BMW argued that targeted localisation across Europe, Asia and North America cuts transit distances and strengthens supply security, while a globally diversified network adds flexibility and resilience. Those are reasonable claims on their face. What BMW did not say is how the new suppliers affect the share of supply held by CATL and EVE Energy, or whether the nominations followed competitive bidding.

Where will the batteries be assembled?

Gen6 high-voltage battery assembly will run at five newly built facilities adjacent to vehicle plants:

• Debrecen, Hungary
• Shenyang, China
• Woodruff, US
• San Luis Potosí, Mexico
• Irlbach-Straßkirchen, Lower Bavaria, Germany

Series production of the batteries began in Shenyang last month, making it the third location in the new global production network for Gen6 technology, after Debrecen and Irlbach-Straßkirchen.

What does this change for BMW's supply chain?

In practical terms, BMW reduces its exposure to any single cell maker and shortens logistics routes between cell plants and vehicle plants. The company itself conceded the limits of the exercise: localising industrial value creation remains highly complex, particularly in cell production, and demands heavy investment plus supply arrangements with global technology leaders willing to build local operations. That admission is the caveat behind every promise of resilience — localisation only works if suppliers can be persuaded, and paid, to set up nearby.

BMW added a political condition. Long-term regional battery ecosystems, it said, depend on feasible regulation and attractive local conditions over the industrialisation periods involved. In other words, the plan's success rests partly on governments, not only on contracts.

What does BMW keep in-house?

The group retains internal development, production and recycling capabilities at three Bavarian competence centres:

• The Battery Cell Competence Centre in Munich researches new cell technologies.
• The Cell Manufacturing Competence Centre in Parsdorf tests near-series cells and evaluates high-quality, resource-efficient production methods.
• In Salching, German circular-economy service provider Encory will build and operate the Cell Recycling Competence Centre, recovering raw materials with BMW's direct recycling method for reintegration into production.

Nicolai Martin, BMW board member for purchasing and supplier network management, said: "We aim to ensure our products' global competitiveness and to be successful in different markets. To achieve this, we operate as locally as possible in our value chains, leveraging the potential of our global procurement markets. Through our battery cell partnerships, we are actively strengthening value creation in Europe and the US."

The statement is a strategy statement, not a commitment with numbers attached. Until BMW publishes volumes, plant capacities tied to each supplier, or timelines beyond "late 2020s", the practical effect of the nominations — who gains share, who loses it, and at what price — remains outside public view.
