Dr.-Ing. Jochen Fassnacht
My work in the advance engineering of innovative traction drive systems for electromobility

My name is Jochen Fassnacht, and I’ve been working as a development engineer for Robert Bosch GmbH since 2002. Right now, I am working as a senior expert on the development of new traction drive systems for electromobility. My area of responsibility includes developing new electric traction drive and control systems and integrating them into the vehicle, along with practically all of the aspects that this entails.

Interview with Dr.-Ing. Jochen Fassnacht

Senior Expert Electrical Drive Systems
Please tell us what fascinates you most about research.
The fascinating thing about research is definitely the shifting of boundaries, in other words, making things possible that were previously impossible and creatively bringing about something new.
What makes research done at Bosch so special?
Working collaboratively across disciplines with such wonderful colleagues from the most disparate fields, the congenial atmosphere, and having the goal of implementing the results of our research, which then improve real life.
What research topics are you currently working on at Bosch?
What does a drive concept for an electric or fuel cell vehicle have to be like for it to fulfill multiple tasks and at the same time be particularly efficient, cost-effective, and environmentally friendly?
What are the biggest scientific challenges in your field of research?
In the system development of modern traction drives, the overview and handling of rapidly increasing complexity are certainly among the greatest challenges for launching really good innovations.
How do the results of your research become part of solutions "Invented for life"?
With a bit of lobbying and of course a great deal of work and effort from a large number of people. Good ideas can come from individuals or from small teams. Innovations, or successful products, require a great deal of effort to be invested by very many people from all areas.
