The BMW Group is bringing large-format, pure ASSB cells from Solid Power to its BMW i7 test vehicle, which is being operated in the Munich area.
The potential benefits of ASSB technology include higher energy density in a very compact storage system compared to current technologies.
Since 2022, the BMW Group and Solid Power have intensified their activities for the development of all-solid-state battery (ASSB) technology through their technology transfer agreement.
With a higher energy density compared to current battery technologies, ASSB batteries have the potential to achieve longer ranges in vehicles without the disadvantages with regard to the weight of the overall storage system.
The concept battery integrated in the BMW i7 test vehicle combines proven Gen5 construction principles with new module concepts for integrating ASSB cells from Solid Power.
Management of cell expansion will be investigated, as well as operating pressure controlled, and how to adjust temperature conditions.
The battery pack will provide the BMW Group with findings in the test program over the coming months. Since 2008, the BMW Group has been expanding its expertise in the area of battery cell technology. Since 2019, this knowledge has been integrated into its Battery Cell Competence Center (BCCC) in Munich.
The cooperation with Solid Power underlines BMW’s battery strategy, which is to further develop innovative battery technologies on equal footing with leading partners in the industry.
John Van Scoter, President and Chief Executive Officer of Solid Power, said:
“Solid Power is extremely proud that our partnership with BMW has resulted in the first demonstration of truly all-solid-state battery cells in a vehicle.
“We believe in the promise of ASSB’s and continue to drive innovation of our sulfide electrolyte in support of that future for EV’s.”
Martin Schuster, Vice President Battery Cell and Cell Module at the BMW Group, said:
“Our BMW i7 ASSB test vehicle on the road is a perfect example of the BMW Group’s technology-open mindset. We are continuously advancing the development of new battery cell technologies and are constantly expanding our know-how with valuable partners such as Solid Power. ”
