Multi-Dimensional Value-Benefit Analysis for Electrified Commercial Vehicle Concepts

Urban commercial vehicles, contrary to passenger cars, are characterized by their auxiliary units which can require a high percentage of the overall energy consumption. Drive train topologies of commercial vehicles can be very complex, especially when the main drive and auxiliary drive are interlinked. In this paper, a structured approach for the evaluation of electrified drive train topology concepts is presented. A multi-dimensional value-benefit analysis is introduced in order to assist in comprehending the specific strengths and weaknesses of each concept. The methodology proves to significantly reduce uncertainty during inter-disciplinary vehicle design. In a case study the methodology is applied to large street sweeping vehicles for metropolitan areas.
