Boysen opens up advantages

in research & development

We work on achieving the ideal relationship between lightweight construction and endurance, emission figures and acoustics. State of the art technology is a must. Practical knowledge and interaction between production and development know-how are vital. This is what enables us to design and develop more efficiently.

This also helps us in the development of battery cases for electric vehicles, where high crash safety, reliable protection of the battery cells, and efficient integration into the vehicle architecture are crucial.

And we are consistently expanding our development activities. In addition to the Development and Administration Centre at our Altensteig headquarter, since 2014 the nearby Boysen Innovation Centre Nagold (BIN) has been primarily concentrating on development and testing in the commercial vehicles sector and acts as an internal service provider to the Altensteig development centre in the passenger car sector. The BAK Development Center in Simmersfeld, which opened in 2024, in turn lays the groundwork for new developments in the areas of battery enclosures, hydrogen technology, fuel cells, and stationary energy storage systems.

This creates scope for innovations and enables our partners to achieve a crucial competitive advantage.
