BMW Group tests all-solid-state battery technology in i7 vehicle
The BMW Group is advancing its exploration of all-solid-state battery (ASSB) technology by integrating large-format ASSB cells from Solid Power into its test vehicle, the BMW i7, currently operating in the Munich area. This initiative aims to leverage the potential benefits of ASSB technology, which offers higher energy density in a compact storage system compared to existing battery technologies. Since 2022, the BMW and Solid Power have intensified their collaboration under a technology transfer agreement to develop ASSB technology. The ASSB technology is expected to enable longer vehicle ranges without the added weight typically associated with current battery systems. The concept battery in the BMW i7 test vehicle combines Gen5 construction principles, featuring prismatic cells in modules, with innovative module concepts designed for integrating ASSB cells from Solid Power. This integration will allow for the investigation of critical factors such as cell expansion management, operating pressure control, and temperature condition adjustments. Solid Power president and CEO John Van Scoter 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 sulphide electrolyte in support of that future for EVs.' BMW believes that the use of Solid Power's cells, which utilise sulphide-based electrolytes, will provide valuable insights during the test programme over the coming months. BMW Battery Cell and Cell Module vice president Martin Schuster 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.' These cells have been developed and manufactured by Solid Power in collaboration with experts from the BMW. The partnership between the companies dates back to 2016, supported by an extended joint development agreement. At the end of 2022, both companies agreed to deepen their partnership, with BMW operating a solid cell prototype line at the Cell Manufacturing Competence Centre (CMCC) in Parsdorf. Since 2008, BMW has been enhancing its expertise in battery cell technology, consolidating this knowledge at the Battery Cell Competence Centre (BCCC) in Munich since 2019.

BMW i7 gets efficiency-boosting solid-state battery in latest tests
BMW has started testing a cutting-edge solid-state battery in its electric i7. The all-solid-state battery – or ASSB – is designed to deliver longer ranges than a current electric vehicle but without the traditional weight penalty associated with a conventional lithium battery. In essence, a solid-state battery could unlock longer ranges from electric vehicles while making them lighter than current EVs. 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. ' BMW and specialists Solid Power have been working together since 2016 following a 'joint developmental agreement' and was supported by an investment by BMW Group in Solid Power in May 2021. While the German manufacturer hasn't stated what level of range the solid-state battery-equipped i7 is returning, a new series of tests will look to see how the technology copes with usual driving scenarios. 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.'

BMW is also field testing solid-state battery tech
The BMW Group has fitted a BMW i7 with a solid-state battery as it charges ahead with testing of the next-generation technology. In unison with tech partner Solid Power, the so-called ASSB pack (all-solid-state battery) uses cells that yield a higher density. However, they are smaller and lighter than those in current lithium ion batteries used today. So more energy can be stored in smaller packs. This prototype uses existing prismatic cells in modules, rather than the more advanced bolted-to-pack cylindrical cells. This suggests BMW could modify its current platforms to take the next-generation technologies. That means it could bring solid state batteries to market quicker than had previously been expected (2033). Martin Schuster, BMW Group's vice-president of next-generation battery tech, admitted that SS tech could be implemented right now. However, the group's main focus was to continue the development of existing lithium-ion techology. He added there was still plenty of potential there. But the new test mule shows the group is hedging its bets. Schuster said BMW has a 'technology-open mindset.' He added 'We are continuously advancing the development of new battery cell technologies.' Solid-state batteries are considered the next big thing for EVs and important for their longevity. For they offer greater capacity and more range than similar-sized batteries used today. Without the need for external cooling, they are also lighter. And they are less susceptible to temperature variations. Critically, they charge more quickly. Mercedes-Benz earlier this year claimed it was close to putting solid state battery technology into production.
