CAD Model Integration Within Multidisciplinary Modelling of Electric Vehicle Energy Storage System

This paper aims to highlight the importance of Computer-Aided Design (CAD) model integration within multi-domain modelling activities. Information about geometrical system size is generally lost in a multi-domain numerical model that focuses on simulating the interactions among different physical system parameters during their operations. For this reason, the present paper proposes a multi-domain modelling approach that uses both geometrical and numerical models to study the behavior of a battery electric vehicle (BEV) energy storage system (ESS). In particular, the numerical model is aimed to simulate thermo-electrical ESS behavior in MatLab/Simulink environment while the geometrical CAD model supports the design activities of different battery cells layout using SolidWorks Dassault software. The objective of this integrated model is to compare the Battery Pack (BP) hotspots of the different designed layout solutions obtained. In conclusion, four different layout solutions have been proposed and compared with some evaluations related to their geometrical size, to test the effectiveness of this multi-domain instrument.
