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.

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.

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 electro
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 (sopre) 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.
