The why, what and how of the electric vehicle powertrain Empowers
engineering professionals and students with the knowledge and
skills required to engineer electric vehicle powertrain
architectures, energy storage systems, power electronics converters
and electric drives. The modern electric powertrain is relatively
new for the automotive industry, and engineers are challenged with
designing affordable, efficient and high-performance electric
powertrains as the industry undergoes a technological evolution.
Co-authored by two electric vehicle (EV) engineers with decades of
experience designing and putting into production all of the
powertrain technologies presented, this book provides readers with
the hands-on knowledge, skills and expertise they need to rise to
that challenge. This four-part practical guide provides a
comprehensive review of battery, hybrid and fuel cell EV systems
and the associated energy sources, power electronics, machines, and
drives. The first part of the book begins with a historical
overview of electromobility and the related environmental impacts
motivating the development of the electric powertrain. Vehicular
requirements for electromechanical propulsion are then presented.
Battery electric vehicles (BEV), fuel cell electric vehicles
(FCEV), and conventional and hybrid electric vehicles (HEV) are
then described, contrasted and compared for vehicle propulsion. The
second part of the book features in-depth analysis of the electric
powertrain traction machines, with a particular focus on the
induction machine and the surface- and interior-permanent magnet ac
machines. The brushed dc machine is also considered due to its ease
of operation and understanding, and its historical place,
especially as the traction machine on NASA's Mars rovers. The third
part of the book features the theory and applications for the
propulsion, charging, accessory, and auxiliary power electronics
converters. Chapters are presented on isolated and non-isolated
dc-dc converters, traction inverters, and battery charging. The
fourth part presents the introductory and applied electromagnetism
required as a foundation throughout the book. - Introduces and
holistically integrates the key EV powertrain technologies. -
Provides a comprehensive overview of existing and emerging
automotive solutions. - Provides experience-based expertise for
vehicular and powertrain system and sub-system level study, design,
and optimization. - Presents many examples of powertrain
technologies from leading manufacturers. - Discusses the dc
traction machines of the Mars rovers, the ultimate EVs from NASA. -
Investigates the environmental motivating factors and impacts of
electromobility. - Presents a structured university teaching stream
from introductory undergraduate to postgraduate. - Includes
real-world problems and assignments of use to design engineers,
researchers, and students alike. - Features a companion website
with numerous references, problems, solutions, and practical
assignments. - Includes introductory material throughout the book
for the general scientific reader. - Contains essential reading for
government regulators and policy makers. Electric Powertrain:
Energy Systems, Power Electronics and Drives for Hybrid, Electric
and Fuel Cell Vehicles is an important professional resource for
practitioners and researchers in the battery, hybrid, and fuel cell
EV transportation industry. The book is a structured holistic
textbook for the teaching of the fundamental theories and
applications of energy sources, power electronics, and electric
machines and drives to engineering undergraduate and postgraduate
students. Textbook Structure and Suggested Teaching Curriculum This
is primarily an engineering textbook covering the automotive
powertrain, energy storage and energy conversion, power
electronics, and electrical machines. A significant additional
focus is placed on the engineering design, the energy for
transportation, and the related environmental impacts. This
textbook is an educational tool for practicing engineers and
others, such as transportation policy planners and regulators. The
modern automobile is used as the vehicle upon which to base the
theory and applications, which makes the book a useful educational
reference for our industry colleagues, from chemists to engineers.
This material is also written to be of interest to the general
reader, who may have little or no interest in the power electronics
and machines. Introductory science, mathematics, and an inquiring
mind suffice for some chapters. The general reader can read the
introduction to each of the chapters and move to the next as soon
as the material gets too advanced for him or her. Part I Vehicles

Basics Chapter 16 Introduction to Electromagnetism, Ferromagnetism,
and Electromechanical Energy Conversion The first third of the book
(Chapters 1 to 6), plus parts of Chapters 14 and 16, can be taught
to the general science or engineering student in the second or
third year. It covers the introductory automotive material using
basic concepts from mechanical, electrical, environmental, and
electrochemical engineering. Chapter 14 on electrical charging and
Chapter 16 on electromagnetism can also be used as a general
introduction to electrical engineering. The basics of
electromagnetism, ferromagnetism and electromechanical energy
conversion (Chapter 16) and dc machines (Chapter 7) can be taught
to second year (sophomore) engineering students who have completed
introductory electrical circuits and physics. The third year
(junior) students typically have covered ac circuit analysis, and
so they can cover ac machines, such as the induction machine
(Chapter 8) and the surface permanent-magnet ac machine (Chapter
9). As the students typically have studied control theory, they can
investigate the control of the speed and torque loops of the motor
drive (Chapter 15). Power electronics, featuring non-isolated buck
and boost converters (Chapter 11), can also be introduced in the
third year. The final-year (senior) students can then go on to
cover the more advanced technologies of the
interior-permanent-magnet ac machine (Chapter 10). Isolated power
converters (Chapter 12), such as the full-bridge and resonant
converters, inverters (Chapter 13), and power-factor-corrected
battery chargers (Chapter 14), are covered in the power electronics
section. This material can also be covered at the introductory
postgraduate level. Various homework, simulation, and research
exercises are presented throughout the textbook. The reader is
encouraged to attempt these exercises as part of the learning
experience. Instructors are encouraged to contact the author, John
Hayes, direct to discuss course content or structure.
