Electric Vehicle Systems and Configurations — Lesson 1

This lesson covers the various systems and configurations of electric vehicles (EVs). It delves into the multidisciplinary engineering domains required for EV systems, including electrical, mechanical, and chemical engineering. The lesson discusses the different types of EVs, such as converted EVs and purpose-built EVs, and their respective designs. It also explains the components of a typical EV system, including the electrical propulsion system, energy source subsystem, and auxiliary power supply. The lesson further explores the different types of mechanical arrangements in a typical BEV system, the differences between single motor and multiple motor-based BEV configurations, and the decision-making process for system voltage in BEV configurations. For instance, a converted EV is an existing vehicle that has been modified to function as an EV, while a purpose-built EV is designed from scratch to be an EV.
