This lesson covers the fundamentals of hybrid electric vehicle systems, their configurations, and their advantages over battery electric vehicles (BEVs). It delves into the energy efficiency of BEVs and the limitations that hinder their mass adoption, such as short driving range, high battery cost, and lack of charging infrastructure. The lesson then introduces the concept of hybridization of resources as a solution to these limitations. It explains how combining the efficiencies of an internal combustion engine (IC engine) and a BEV can lead to improved energy efficiency and reduced emissions. The lesson also discusses different types of hybrid electric vehicles, including series hybrid, parallel hybrid, series-parallel hybrid, and complex hybrid, and their respective advantages.
