Powertrain test benches play an essential role in the development and validation of new drive systems. So far, none of the many different concepts for electrified or hybrid powertrains has been able to clearly establish itself. This diversification leads to an increased scope and complexity of tasks in the powertrain test field. This requires extended methods and new test bench components.

The presentation gives an overview of the different types of powertrain test benches and their special design for electrified drive systems, with a focus on the increased complexity of heavy-duty and off-highway applications.
