eMobility Systems

The alternative drive of your sector

We are at your side for everything relating to alternative drives. We will accelerate technological progress for you throughout the entire development process of your e-drive development, from design to integration. Your individual needs are our key focus. To this end, we offer you scalable project teams providing a winning combination of passion and customer focus, and – together with our colleagues in “Testing Solutions” – can provide our own infrastructure for the testing, virtual verification and certification of your solution.

As diverse as our teams: Automotive, Avionic, Rail and Sea

We have a clear vision for the development of electric powertrains: dynamic, quiet and with zero emissions. To achieve this, we provide you with excellence from a single source. Our experts have successfully completed hundreds of projects over the last decade. We can now make this know-how available to you. From development to validation, we offer you scalable project teams that profitably combine passion with customer focus. In doing so, we make use of multi-departmental functions to optimize costs. Our own testing infrastructures also ensure reliable validation of our development and application.
