Abstract
Modern electric machines operate within a wide range of torque-speed operating points. Real drive cycles of a real vehicle cannot be tested in the given lab with machines that have smaller ranges and thus the drive cycles need to be down-scaled. To allow for experimental investigations of such driving scenarios even in small laboratory scale analyses, this paper presents a method of down-scaling the drive cycles of different vehicles. Three test case speed-over-time drive cycles are chosen and analysed with two different electric vehicles to derive the corresponding torque-speed profiles for the study. These drive cycles are down-scaled to fit the ratings of the two laboratory test case motors. The down-scaling method aims to replicate the torquespeed characteristics of the original driving cycle while considering the specific characteristics of the motors being used in the laboratory. The effectiveness of the proposed down-scaling method is demonstrated.
