Early Stage Design of an Electric Drive Train for a Heavy Duty Transport Vehicle

Abstract

This paper presents design considerations for the creation and optimization of the electric drive train (EDT) of an electric heavy duty vehicle (HDV). An analytical sizing tool is also created that takes into account the requirements and guidelines for HDVs, a comparison of state-of-the-art electric trucks, and an estimation of the physical demand of a sample long-haul transport drive cycle (DrC). As an EDT evaluation criterion, compliance with the ideal DrC of the vehicle is analyzed and a rough design for an axial flux machine is developed. By this method, the groundwork is laid to carry out a multi-domain optimization of the entire EDT in the future.
