Measuring and Characterization of a Pedal Electric Cycle (Pedelec) Drivetrain on a Test-Bench for Modelling and Optimization

This paper shows the extended characterization of a pedelec drivetrain and the construction of the necessary test-bench. The test-bench construction for a drivetrain only enables thereby reproducible, comparable and precise measurement. This allows the control and electromagnetic design of a pedelec drive to be optimized during development. In addition, parameterized simulation models based on special measurement methods enable simulation-based development of pedelecs. Likewise, the test-bench is able to perform a range measurement of R200 [1] easily and automatically as well as the reachable height. This paper shows the structure, the design and the operation of the drivetrain test-bench as well as the measurement routines, methods and the results of a device under test pedelec drive unit.
