BMW Begins Actual-World Testing of Strong-State Batteries within the i7 Sedan : Automotive Addicts

Automotive

BMW is taking a significant step towards the way forward for electrical automobile expertise by starting real-world testing of all-solid-state battery (ASSB) cells in a BMW i7 check automobile. Developed in collaboration with Colorado-based Strong Energy, this prototype marks the primary time large-format solid-state cells have been built-in into a totally operational BMW automobile and pushed on public roads.

The testing, at present underway within the Munich space, represents a big milestone within the BMW Group’s long-term technique to deliver next-generation battery expertise to its EV lineup. Strong-state batteries have lengthy been seen as a possible game-changer in electrical mobility, promising larger vitality density, improved security, and, finally, decrease manufacturing prices.

Not like conventional lithium-ion batteries, which use liquid electrolytes, solid-state batteries depend on stable supplies to maneuver ions between the anode and cathode. This eliminates the chance of leakage or hearth related to liquid cells, whereas additionally permitting for a extra compact and energy-dense package deal. For drivers, that might translate to longer vary, faster charging, and a extra sturdy battery pack with fewer compromises.

BMW’s check automobile makes use of ASSB cells based mostly on sulfide-based electrolytes developed by Strong Energy. These superior cells are built-in into an idea battery pack that builds on the fifth-generation (Gen5) prismatic cell structure already present in BMW’s present EVs. Nevertheless it’s not only a plug-and-play swap. Engineers are utilizing the i7 testbed to review how the solid-state modules behave beneath real-world situations — from managing cell enlargement to optimizing strain and thermal situations throughout the pack.

“This check automobile is an ideal instance of our technology-open method,” mentioned Martin Schuster, Vice President of Battery Cell and Cell Module at BMW. “We’re continuously pushing the boundaries of what’s attainable, and partnerships just like the one we have now with Strong Energy are key to that progress.”

Strong Energy CEO John Van Scoter additionally expressed enthusiasm for the breakthrough, stating, “We’re extraordinarily proud that our partnership with BMW has resulted within the first demonstration of really all-solid-state battery cells in a automobile. We imagine strongly within the promise of this expertise.”

The collaboration between BMW and Strong Energy isn’t new. The 2 corporations have labored collectively since 2016 and formalized their partnership with a joint improvement settlement and a BMW funding in 2021. As a part of their deepening cooperation, BMW will even function a solid-state prototype cell manufacturing line at its Cell Manufacturing Competence Heart (CMCC) in Parsdorf, Germany. The power will use Strong Energy’s supplies and experience beneath a analysis and improvement license to speed up in-house information and manufacturing capabilities.

For the BMW Group, this transfer is a part of a broader effort to remain on the forefront of battery innovation. Since 2008, the corporate has been steadily investing in battery R&D, culminating within the Battery Cell Competence Heart (BCCC) in Munich, which brings collectively analysis, design, and prototyping beneath one roof. At this time, BMW works with greater than 300 companions throughout the globe — from startups to universities — to make sure it stays linked to the most recent breakthroughs in vitality storage expertise.

Because the automotive business races towards electrification, solid-state batteries are extensively seen as probably the most promising developments on the horizon. Although nonetheless within the early phases of real-world implementation, BMW’s work with Strong Energy might be a significant step in bringing this high-potential expertise nearer to mass manufacturing. If profitable, solid-state cells may result in EVs that cost quicker, drive farther, and last more — all whereas utilizing safer, extra environment friendly battery designs.

This check program with the i7 could also be a preview of what’s to come back, and it places BMW in a powerful place to guide the following part of electrical automobile evolution.
