eMobility Systems. Intelligent e-drives for all industries.

Electric and alternative drives: We develop the complete e-drive for you. Put your trust in our years of experience, whether in hardware or software development or in project engineering. Our experts have a comprehensive command of the process: Design, development and integration, and everything from virtual validation to hardware testing. Whether for components, subsystems or the entire vehicle. The applications are as diverse as our teams: Automotive, avionics, rail and sea.

Excellence in all dimensions: Transversal skills meet expert knowledge for the next generation of drive systems.

We have a clear vision for the development of electric drive systems: Dynamic, quiet, emissions free. For this we provide you with expertise, all from one source. In over a decade our experts have brought hundreds of projects successfully across the finish line. We offer you the benefit of this expertise. From development to validation, we offer you scalable project teams that profitably combine passion with customer orientation. We achieve cost optimizations by applying functionalities from across departments. On top of that, reliable validation of our developments and applications is guaranteed by our own testing infrastructures.
