Target Group
The course has been designed for automotive/mechanical engineers and researchers, with the aim of reviewing xEV technology and the challenges and opportunities associated with e-mobility. Prof. Rizzoni has been engaged in engineering research and education in e-mobility for over 30 years; this course represents a compendium of material he teaches in a graduate level course at The Ohio State University, and it is designed to provide a comprehensive introduction to the subject matter to automotive/mechanical engineers without significant prior exposure to the subject.

Module 2: Computational Laboratory
BEV laboratory, with focus on regenerative braking
The day closes with a laboratory in which the participants will explore the simulated performance of a BEV using a simulator that is capable of simulating many important aspects of a battery electric vehicle including regenerative braking. Demonstrations and exercises in simulation focus on understanding the interaction of electromechanical regenerative braking with friction braking, with consideration of braking performance, energy recuperation and vehicle stability.
