PREFACE:
While it can be very useful for writing and teaching to be at a distance from the developing story, it is important not to be detached or isolated from such developments. My co-author, Abas Goodarzi, is a former colleague who is living and working to deliver the new technologies.
Abas and I started work together at the General Motors’ Hughes Aircraft subsidiary in Culver City, California, in October 1990. After directing the development of the EV1 electric powertrain, Abas pursued an electric vehicle start-up.
After working in a few more start-ups, Abas founded US Hybrid, where he remains CEO. US Hybrid is a company specializing in delivering battery, hybrid, and fuel cell solutions for heavy-duty transportation. Between us, we have been part of engineering teams which have developed for mass production all of the technologies discussed in this book.
The modern automobile is a great topic for teaching because it is a consumer product to which all students, family, and friends can relate and discuss. Also, it features engineering marvels such as energy storage, combustion engines, electric drives, power electronics, and more.
The structure of this book is set up to explain how these technologies interact in the vehicle as a whole and then becomes more technical as the book or a particular chapter unfolds. The book features problems and assignments of varying technical difficulty for university students.
The reader can attempt them based on his or her level. The car and electrical technology have a history rich with the contributions of many prominent people. Hence, their quotations are often included at the start of a chapter. They generally tie in with the story or underlying philosophies…and are often fun and thought-provoking.
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. I teach the material across four years here at University College Cork. The material can be taught across various years as outlined in Table I. 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) are 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 we cover ac machines, such as the induction machine (Chapter 8) and the surface permanent-magnet machine (Chapter 9).
As the students typically have studied control theory, we 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), is also introduced in the third year.
