Concept of drive cycle - I — Lesson 1

This lesson covers the importance of energy in vehicles, the concept of energy efficiency, and how it impacts the performance of a vehicle. It explains how energy is like fuel for a vehicle, determining the range it can travel. The lesson also discusses the design of motor controllers and batteries, the role of voltage, and the impact of current on heat dissipation. It further delves into the concept of losses in each subsystem of a vehicle, including heat loss and magnetic loss. The lesson also introduces the concept of a standard drive cycle, which helps in comparing the energy efficiency of different vehicles.
