Design Optimization of Electric Kart for Racing Sport Application

This paper presents a design optimization for an electrical kart that will be used in sport racing competitions. This work is carried out within the project "E-Kart", sponsored by University of Naples Federico II, that consists in developing integrated high-tech devices for the design and implementation of electrical drive using high density of Lithium Ion Batteries Technology. The aim of paper is the preliminary sizing of the main components of electrical drives for satisfying the performance requirements in terms of minimizing time lap, considering constraints like maximum speed for lap, maximum weight of battery systems and dynamic force of racetrack (e.g. curve and straight). The paper shows the optimal design procedure on basis of fixed racetrack identifying the speed profile, output mechanical power to the wheel and kWh of Energy Storage Device.
