BMW has confirmed that it will use Samsung SDI batteries for its electric vehicles on the Neue Klasse platform. This makes Samsung SDI one of the sixth-generation battery cell suppliers for future BMW electric cars, continuing a partnership that has lasted 17 years.
The new agreement is directly linked to the Neue Klasse platform. BMW will use cylindrical battery cells with a 46mm diameter in these vehicles, which will be produced in two formats. The first format, designated 4695, is 95mm high, while the second format, designated 46120, has a height of 120mm.
In addition to Samsung SDI, the sixth-generation battery suppliers include LG Energy Solution, CATL and EVE Energy. BMW states that the new generation of batteries offers approximately 20 per cent higher energy density compared to previous prismatic cells. Furthermore, an increase of up to 30 per cent in the range of electric vehicles and approximately 30 per cent faster charging are expected.
Samsung SDI is preparing a production line for 46-series cylindrical cells at its existing factory in Göd, Hungary. Mass production is planned to begin in 2028. Samsung SDI batteries are expected to have higher energy density and faster charging, aligning with the announcements BMW has made regarding the new battery generation.
The selection of suppliers for the Neue Klasse platform is part of BMW’s broader planning for next-generation electric models. The combination of 46mm diameter cylindrical cells in two formats and multiple suppliers is intended to ensure production capacity for these vehicles.
