A modified Mercedes-Benz EQS equipped with a solid-state battery<\/strong> has achieved a range of 1,205 km<\/strong> on a single charge. The journey, which went from Stuttgart to Malm\u00f6, left the car with an additional 137 km<\/strong> of range remaining.<\/p>\n\n\n\n

Mercedes-Benz<\/a><\/em><\/strong> conducted a significant test that sheds light on the future of electric mobility<\/strong>. A modified EQS, fitted with a solid-state battery, completed the 1,205-kilometer trip from Stuttgart to Malm\u00f6 on a single charge. This drive, which took place at the end of August, proved that the new battery technology can work reliably not just in a laboratory setting, but also under real-world road conditions<\/strong>.<\/p>\n\n\n\n

The era of solid-state batteries<\/strong> is very near.<\/h2>\n\n\n\n

The result surpassed the brand’s previous record. The 1,202-kilometer distance covered by the Vision EQXX from Stuttgart to Silverstone was beaten by three kilometers. Upon arriving in Malm\u00f6, the EQS still had 137 kilometers<\/strong> of range left, which means the total potential range was 1,432 kilometers<\/strong>.<\/p>\n\n\n\n

Mercedes-Benz had planned this journey as part of a comprehensive testing program announced in February. The EQS departed from Stuttgart and traveled through German and Danish highways to reach Sweden. The electric navigation system<\/strong> factored in road gradients, traffic, temperature, and heating\/cooling needs when determining the route.<\/p>\n\n\n\n

The company, which aims to test the performance of solid-state battery technology in various climates and on long routes, continues its validation work in daily-use scenarios<\/strong>, in addition to laboratory and simulation tests.<\/p>\n\n\n\n

The battery system<\/strong> was developed in collaboration with Mercedes-AMG High Performance Powertrains (HPP)<\/strong> and the American cell manufacturer Factorial Energy<\/strong>. The cells used are based on a technology the company calls FEST (Factorial Electrolyte System Technology)<\/strong>.<\/p>\n\n\n\n

In this new system, pneumatic actuators<\/strong> are used to compensate for the typical volume changes that the battery experiences during charging and discharging. This keeps the cells under the necessary pressure, ensuring performance stability<\/strong>. Furthermore, while the battery capacity<\/strong> has been increased by 25%<\/strong>, its size and weight remain almost the same as a standard EQS battery. Additionally, passive airflow cooling<\/strong> contributes to its energy efficiency.<\/p>\n\n\n\n
