High-Performance Electric Powertrain Test Bench

The test bench enables the testing of complete powertrains or individual components (e.g. eDrives or gearboxes) from electric vehicles. The driving resistances are simulated by two highly dynamic eDrives. The input is provided either by the drive of the device under test (DUT) or a dynamic eDrive of the test bench. A highly dynamic high-voltage battery simulator is used to supply the DUT with electrical energy. A comprehensive range of test bench equipment is available for operating and analysing modern drivetrains.
