Vehicle electrification architecture trade studies, analysis and synthesis

Off-highway and heavy duty vehicles systems consist of heterogeneous system elements. Development of scalable electrification architectures for such vehicles requires deep understanding of operating loads, duty cycles and careful consideration of complex system interfaces of electrified sub­systems and functions both the vehicle and its attachments. This paper explains some of the techniques to perform detailed analysis of electrification architectures using design structure matrices, network analysis, clustering methods and reliance on simulations for electrification architecture synthesis. One example of series hybrid architecture will be discussed in detail covering the critical aspects of architecture development, analysis and synthesis in this paper.
