Investigations on the Impact of Different Electric Vehicle Traction Systems in Urban Traffic

Abstract

Currently electric vehicles are introduced in e.g. public transport and individual traffic in order to reduce i.a. the green house gas emissions. The main disadvantage of electric vehicles compared to vehicles with conventional drive is the shorter operating distance. In contrast this disadvantage is partially negligible in urban usage scenarios, like e.g. taxi or delivery services. This paper focuses on the simulation of electric vehicle propulsion systems using a Hardware in the Loop (HiL) model. The model consisting of components used in actual electric vehicles is scaled using Buckingham's Pi-Theorem in order to analyze the impact of different electric traction systems on the vehicle's energy consumption. Thus the available operating distance of such vehicles can be optimized in urban traffic.
