Preface
Hybrid electric vehicles are a mature technology for road applications and of increasing in‐
terest in other fields including aircraft. They rely on the use of two different forms of energy
storage (a fuel and a battery) and try to optimize the energy flows between the correspond‐
ing energy converters (electric machines and thermal engines). Several studies in literature
have pointed out the advantages of HEVs versus conventional vehicles in terms of fuel
economy and environmental impact. They are mainly due to the flexibility in the choice of
engine operating point that allows the engine to be run in its high efficiency region and to be
downsized, so obtaining a higher average efficiency. Moreover, the engine can be turned off
when the vehicle is arrested (e.g., at traffic lights) or the power request is very low (reduc‐
tion of the idle losses). Compared with battery electric vehicles (BEVs), they have longer
driving ranges with smaller (and lighter) batteries and the same possibility of grid recharg‐
ing in the case of plug-in hybrid electric vehicles (PHEVs). BEVs, HEVs, and PHEVs have
also the capability of partially recovering energy from brakes by inverting the energy flow
from batteries to wheels through the electric machine.
This book on hybrid electric vehicles brings out six chapters on some of the research activi‐
ties through the wide range of current issues on hybrid electric vehicles: choice of the best
architecture, performance of converters and storage systems, energy management strategies,
effect of specific driving conditions, power electronics, etc. Actually, these aspects can be
hardly separated; in fact, they must be addressed together in order to fully exploit the po‐
tentiality of HEVs. Nevertheless, the contributions to this book have been separated in two
sections. The first section deals with two interesting applications of HEVs, namely, urban
buses and heavy duty working machines. The second one groups papers related to the opti‐
mization of the electricity flows in a hybrid electric vehicle, starting from the optimization of
recharge in PHEVs through advance storage systems, new motor technologies, and integrat‐
ed starter-alternator technologies.
A comprehensive analysis of the technologies used in HEVs is beyond the aim of the book.
However, the content of this volume can be useful to scientists and students to broaden their
knowledge of technologies and application of hybrid electric vehicles.
I would like to thank InTech Publisher for inviting me to be the editor of this volume, Ms.
Martina Usljebrka, and the whole Publishing Process Staff for their help in coordinating the
reviews, editing, and printing of the book.
