Electric Vehicles and Their Challenges — Lesson 3

This lesson covers the various types of electric vehicles (EVs), their classifications, and the challenges they face. It begins with an overview of how EVs can be classified based on propulsion devices, energy sources, and energy carriers. The lesson then delves into the specifics of pure electric vehicles and hybrid electric vehicles, explaining their operation and energy sources. It also discusses the different types of hybrid vehicles, including micro hybrid, mild hybrid, full hybrid, plug-in hybrid, and range extended hybrid electric vehicles. The lesson concludes with a detailed discussion on the challenges faced by each type of EV, such as range anxiety, high initial costs, lack of charging infrastructure, and safety concerns.
