Configurations & Operations of Hybrid EVs — Lesson 3

This lesson covers the intricate details of Hybrid Electric Vehicle (HEV) systems and their configurations. It delves into the different modes of operation of HEVs, including starting the system, acceleration, deceleration, normal driving, regenerative braking, and battery charging. The lesson also explores the different types of HEV configurations such as series, parallel, series-parallel, and complex HEVs. It further discusses the advantages of each configuration and how they operate under different conditions. For instance, the lesson explains how a complex HEV can balance axle power during sliding conditions, making it suitable for difficult terrains.
