BMW Tests New EV Battery

BMW’s EV Battery Revolution

Electric vehicle enthusiasts, get ready for some exciting news from BMW. The German automaker is diving headfirst into the future with real-world testing of its all-solid-state battery (ASSB) technology in a BMW i7 prototype. Partnering with Colorado-based Solid Power, this breakthrough innovation is already being put through its paces on the public roads around Munich. It marks the first time that BMW has integrated large-format solid-state cells into one of its vehicles for actual driving conditions.

Solid-State Synergy

This collaboration has resulted in BMW’s i7 test vehicle using ASSB cells that utilize sulfide-based electrolytes—a leap forward from conventional lithium-ion batteries that depend on liquid electrolytes. What sets solid-state batteries apart is their solid materials, eliminating risks like leakage or fire, common with traditional batteries. This not only makes for a safer ride but also means more energy can be packed into a smaller space, providing potentially longer ranges and shorter charge times for drivers.

Engineering Challenges

BMW’s engineering team isn’t just popping these revolutionary batteries into the i7 and calling it a day. They’re carefully evaluating how these solid-state modules function under real-world conditions, such as managing cell expansion and regulating thermal and pressure conditions. All this data will inform future iterations and help ensure these batteries meet BMW’s high standards for performance and safety.

Pioneers in Partnership

Since 2016, the partnership between BMW and Solid Power has been fueling advancements in battery technology. Their joint development agreement, formalized in 2021, included BMW taking an investment plunge, demonstrating their commitment to this promising technology. BMW’s production line for solid-state prototype cells in Parsdorf, Germany, represents a crucial part of their collaborative efforts and ambitions.

The Future of EVs

Solid-state batteries could revolutionize the EV market by promising longer drive ranges, faster charging, and extended battery life—all while being safer and more environmentally friendly. BMW’s active role in pushing this technology adds another chapter to their history of innovation and places them at the forefront of electrification trends. As they conduct real-world tests, the implications are clear: more efficient and powerful EVs are just around the corner.

Imagine a car that not only charges quickly and drives further but also does so with a battery pack that’s built to last longer. BMW’s journey with all-solid-state batteries could be the key to achieving this reality. This testing with the i7 doesn’t just showcase BMW’s pursuit of innovation; it might very well define the next phase of electric vehicle technology.
