BMW tests i7 with solid-state batteries
BMW has taken another step in the development of solid-state batteries by presenting a test prototype based on the i7. This technology, developed together with Solid Power, could become the future of electric vehicles due to its advantages.
The company plans to study the behavior of the batteries in real-world conditions, including temperature ranges and pressure. As noted by BMW:
“The use of Solid Power’s sulfide electrolyte cells and their full integration into the battery pack will provide the BMW Group with important data as part of the test program in the coming months.”
Technology prospects
Despite the optimism, BMW notes that mass production of solid-state batteries is still a long way off. The technology requires further refinement to become competitive. However, Martin Schuster, the company’s battery expert, emphasized:
“Our test i7 with a solid-state battery is a perfect example of the BMW Group’s openness to new technologies. We are constantly developing new solutions for battery cells and expanding our knowledge thanks to partners like Solid Power.”
In addition to BMW, other automakers such as Mercedes and Stellantis are also actively working on solid-state batteries. For example, Stellantis plans to release test versions of the Dodge Charger Daytona by the end of the year with batteries featuring an energy density of 375 Wh/kg.
Although the exact timeline for the appearance of solid-state batteries in production vehicles remains unknown, progress in this field is accelerating. The technology could significantly change the electric vehicle market by offering drivers greater autonomy and reliability. Recent tests by BMW show that the industry is moving in the right direction, despite the technical challenges that still remain.
