Vehicle Design

This paper takes analyses electric car styling design with a focus on low aerodynamic drag. The design starts with an ideal low-drag shape, and then develops the shape into a car styling. With the method of Computational Fluid Dynamics, and after several iterations between design refinement and aerodynamic optimization, the Coefficient of Drag (CD) finally resulted in 0.19, which is quite low for electric cars for saving energy and further the driving range.

In this paper a new design model of the electric vehicle is presented. This model is based on the combination of Modelica with ModelCenter. Modelica has been used to model and simulate the electric vehicle and ModelCenter has been used to optimize the design variables. The model ensures that the requirements related to driving distance and acceleration are fulfilled.

This article addresses a common issue in the design of battery electric vehicles (BEVs) by introducing a comprehensive methodology for the modeling and simulation of BEVs, referred to as the “PerfECT Design Tool”. The primary objective of this study is to provide engineers and researchers with a robust and streamlined approach for the early stages of electric vehicle (EV) design, offering valuable insights into the performance, energy consumption, current flow, and thermal behavior of these advanced automotive systems.
