Drive and Control System for Hybrid Electric Vehicles

Abstract

Weng Keong Kevin Lim, Saman Kumara Halgamuge, and Harry Charles Watson Hybrid vehicles have multiple power sources that can be separately or simultaneously used to propel the vehicle. Different ways of integrating these power-producing components with electrical energy storage components allow for distinct types of hybrid electric vehicle (HEV) configurations. Generally, fuel energy may be converted by a number of distinct heat engines, such as an internal combustion engine (ICE), while an electrical motor (EM) derives its electrical energy from batteries, ultracapacitors, solar cells, fuel cells, or generators driven by heat engines or flywheels. To date, the most promising hybrid vehicle is the HEV driven by an ICE and an EM powered by on-board batteries. HEV solves many pure electric vehicles’ problems and minimizes the shortcomings of conventional vehicles, while providing the benefits of both electric and conventional vehicles.
