Electric powertrains are used in vehicles of all scales: from sub-compact to performance passenger cars; from light vans to articulated 16-wheelers; from forklifts to excavator for off-road and construction vehicles.
Even in vehicles of the same type, the concept of an electric powertrain is often implemented in different ways. In passenger cars, for example, the scope of the powertrain under test may range from a single e-axle with two driven wheels, through dual e-axle with four driven wheels, to two (or more) individual hub motors. Powertrain analysis on a static test rig may therefore involve between one and four motors, between one and four inverters, and between two and four dynamometers. The sheer variety of contemporary electric powertrain designs requires a drivetrain test and measurement solution that is both flexible and extensible.
