Truck & Bus



Freudenberg Sealing Technologies thinks e-mobility in new dimensions: Buses, Trucks, trains, ships and other industrial applications such as construction and agricultural machinery. Today, our tried-and-tested complete high-tech system solutions provide precisely tailored answers to tomorrow’s mobile transport requirements. Electric buses powered by high-performance batteries or trucks without nitrogen oxides are already a reality. In the areas of thermal management, safety and multifunctionality, we are continuously advancing innovative e-mobility technologies.

To this end, Freudenberg is developing large-format high-performance batteries with XALT Energy. In addition, we are also working in the fuel cell sector with innovative solutions, including perfectly matched, intelligent combinations of batteries and fuel cells. For a powerful and sustainable mobile future.


“The demands placed on batteries and fuel cells in terms of cycle stability, operating hours and general service life in the heavy-duty business are significantly higher than with cars. This challenging task profile suits our technology and innovation competence just fine.”

Nils Martens, Senior Vice President of the Battery & Fuel Cell Systems Division, Freudenberg Sealing Technologies

We are continuously expanding our explicit know-how as a comprehensive supplier in the field of future-oriented drive systems: This is ensured by worldwide acquisitions and technological partnerships in battery and fuel cell technology. By acquiring a majority interest in the American battery company XALT Energy, Freudenberg Sealing Technologies has developed into a leading supplier of battery modules and systems. More than 60 technology patents in fuel cell technology prove our claim and decades of core expertise in this area.



Our decades of materials and technology know-how are unparalleled anywhere in the world. But it is only together with the innovative strength of our engineers that Freudenberg develops new material and design concepts for tomorrow’s mobility. We provide well-founded answers to important challenges in the further development of e-mobility. We counter rising energy densities, for example, with intelligent multifunctional solutions in thermal management and functional reliability. Benefit from the high quality and efficiency of our products on your specific path into the mobile future.
