Mercedes-Benz EQS Prototype Sets New Standards for Electric Vehicles
The Mercedes-Benz EQS prototype, equipped with an innovative solid-state battery, covered 748.8 miles (1205 km) from Stuttgart to Malmö without a single recharge. This demonstrates the potential of the new technology to significantly increase the range of electric vehicles.
Solid-State Batteries: Prospects and Advantages
Solid-state batteries have long been considered a key technological breakthrough for electric vehicles, as they promise greater range, faster charging, and increased safety. Mercedes-Benz has finally demonstrated just how revolutionary this technology can be.
The German automaker is testing solid-state batteries in specially prepared EQS prototypes. One such car recently made a trip from Germany through Denmark to Sweden, covering an impressive distance without a single stop for charging.
Comparison with Existing Technologies
Compared to the standard EQS battery, the Mercedes solid-state battery provides 25% more energy while maintaining similar weight and dimensions. The development was carried out in collaboration with Mercedes-AMG High Performance Powertrains and the company’s technology center in the UK, using lithium-metal cells from the American Factorial Energy.
This distance exactly matches the world record set by the Lucid Air Grand Touring, which also covered 748.8 miles on a single charge. However, Lucid used a conventional lithium-ion battery, while Mercedes achieved this result with a solid-state battery that still had significant energy reserves.
Further Possibilities and the Future of the Technology
If Mercedes-Benz had decided to continue the journey, the EQS could have covered another approximately 85 miles, resulting in a theoretical total range of up to 834 miles. This significantly exceeds the figures of any production electric vehicles available on the market today.
The solid-state battery is a true breakthrough for electromobility. The EQS’s successful long journey demonstrates that this technology works not only in the laboratory but also on the road. Our goal is to implement such innovations in series production by the end of the decade and offer customers a new level of autonomy and comfort.
This success highlights that solid-state batteries could become the foundation for future electric vehicles, providing not only longer range but also more efficient use of space and weight. Investments in such technologies could accelerate the transition to clean transportation, making electric vehicles more practical for daily long-distance use. Furthermore, it could help reduce dependence on frequent charging infrastructure, especially in regions with limited access to it.
