The round cells have a diameter of 46 millimetres and will be used for the purely electric propulsion of future BMW models.
The BMW Group officially introduced the cylindrical cell format in September 2022. The aim of the partnership between the BMW Group and EAS Batteries was to accelerate the development of battery cells and thus give BMW a time advantage. And they succeeded.
"EAS Batteries provided us with excellent support in the initial phase of round cell development, for example by supplying prototype cells, and significantly shortened the development time of the BMW cell," said BMW Group Battery Cell Technology Director Peter Lamp.
EAS Batteries provided BMW with both mechanical and electrochemical support, enabling BMW to bring forward decisions on the design and chemistry of the new cell to an earlier stage and define the corresponding processes in a timely manner. BMW will continue to rely on its technology partnership with EAS in the future.
Michael Deutmeyer, Managing Director of EAS Batteries GmbH, emphasizes the contact: "By licensing our patented contact technology, 'flange contact', we are making a decisive contribution to ensuring the high-current capability of the new BMW cell design."
EAS Batteries has positioned itself in the automotive market in a very short time. The automotive industry first turned to the highly specialized niche supplier for large format round cells in September 2020, at which point interest in joint developments with EAS Innovation Factory skyrocketed.
The Nordhausen-based producer of innovative cell and battery solutions now supports a wide range of cell development projects for prestigious automotive companies worldwide.
"Knowledge of EAS is of great importance to the automotive industry," said Michael Deutmeyer.
"Specific load currents require cells with high current capacity. EAS has already perfected them," he stressed.
