EV Subsystem Design of Drive Train

This course covers the comprehensive design and functioning of electric vehicle subsystems, with a particular focus on the drive train. It begins by distinguishing the common parts shared with petrol vehicles, such as the body, frame, doors, power windows, wheels, and suspension system, and then delves into the unique components of electric vehicles. These include the electric motor, controller, battery pack, and vehicle control unit. The course also explores the impact of various parameters like rolling resistance, aerodynamic coefficient, vehicle frontal area, weight, slope, pickup acceleration, and regeneration on the design of electric vehicles. Furthermore, it provides an in-depth understanding of how to calculate vehicle torque, speed, and power, and the role of gears in these calculations. The course also discusses the intricate details of the drive train, battery, DC-DC converter, and auxiliary control units, and their significance in the overall functioning of an electric vehicle. For instance, it illustrates how the energy consumption of air conditioners and heaters can significantly reduce an electric vehicle's range.
