Powertrain test station

The powertrain test station provides the research with attributes on power trains in connection with electric motors. There are several aims of research, e.g. to proof the compliance of certain parameters (production support) or to optimize attributes like tightening behavior or efficiency (development).

Therefore the powertrain test station is operated in several modes:

  • Dynamometer

At dynamometer the parameters like speed and torque as well as the power is calculated and shown in a characteristic curve (speed / torque curve)

  • Life test rig

At life test rig the powertrain is operated in continuous operation and monitored how the parameters of the e-motors change.


Important
components of the powertrain test station are the dynamometer as well as board supply emulators.

The test stations enable simulated test conditions from -40 °C up to +120 °C by use of climatic chambers, cooling circuits and cryostat circuits and offer necessary information to be able to optimize the e-motor by several environmental conditions.
