As a specialised engineering service provider in the field of high-voltage systems, voltmeister supports you in the development of HV systems.
With years of experience in the automotive industry, we develop and test complete and partial HV systems, HV test benches and rest bus simulations for you.

voltmeister was founded in 2021 by Daniel Ettenhuber. Originally planned as a consulting company for commercial electromobility and electric commercial vehicles, he soon realized the great need for training and consulting on the subject of HV safety. A strategic reorientation followed in 2023, combined with the first expansion of the team.
