Samsung SDI and Mercedes Benz Negotiate Major Battery Contract for European EV Production Amidst Political Changes in Hungary and Global Market Cooling
The parties Samsung SDI and Mercedes Benz have reached a stage in their talks which will soon determine the outcome of their prismatic battery cell supply agreement for upcoming electric vehicle models. The industry sources report that the agreement, which targets the 2028 model year, could result in a contract valued at more than 10 trillion won. The German automaker views this partnership as a fundamental change of direction because it has struggled with its plans to acquire batteries through the Automotive Cells Company (ACC) joint venture. The supply agreement which Mercedes proposed requires prismatic batteries with high power capabilities to supply energy density requirements for its Modular Architecture (MMA) platform.
In the last year both companies have increased their strategic collaboration activities while Samsung Electronics Chairman Lee Jae yong and SDI President Choi Joo sun held senior executive meetings with Mercedes executives. The upcoming agreement will enable Mercedes Benz to use Samsung SDI cells in their electric vehicle collection through this historic partnership. The current discussions focus on creating a major European production site while Austria Slovakia and the Czech Republic serve as the main options for establishing the new facility. The South Korean manufacturer needs this localization to meet European Union industrial requirements while maintaining dependable long term supply chains.
The current political unrest in Hungary which serves as a primary battery manufacturing hub for South Korea has halted production growth throughout Europe. The Tisza Party led by Péter Magyar won the most recent elections which created new operational conditions for both Samsung SDI and SK On. The party now possesses sufficient power to change the constitution after it secured a mandate which allows them to enforce strict monitoring of battery production sites to protect local environmental conditions and worker safety. The Göd based factory operated by Samsung SDI and the production sites managed by SK On have already faced investigations and public criticism. The new government plan to review industrial permits and subsidies will create major disruptions which will affect Ecopro BM and other key suppliers throughout the regional supply chain.
The South Korean battery industry is experiencing dual operational difficulties while the sector begins its early 2026 cooling period. The first quarter financial results show that LG Energy Solution and Samsung SDI and SK On faced operational losses because of the electric vehicle market stagnation and the United States withdrawal of manufacturing tax credits. Manufacturers are now converting their non operational electric vehicle battery production lines to manufacture Energy Storage Systems (ESS). The second half of the year will bring financial recovery according to analysts yet the substantial profitability gap between high density vehicle batteries and lower margin ESS solutions will continue to obstruct progress.
The future of the domestic battery industry depends on both international regulatory frameworks and the response of government authorities in the country. The South Korean government is considering a domestic production tax incentive program while manufacturers request direct cash subsidies to handle their current operating losses. The potential Mercedes Benz contract represents a crucial opportunity for Samsung SDI to solidify its position in the European market.
