This is the first and only book that covers hybrid vehicles in a practical way and is designed for the service technician or automotive student. Beginning with an explanation of the fundamentals, the book discusses historical trends and concerns for the environment, and then moves on to more detailed concepts of systems. It devotes separate chapters to each system and then highlights products from leading manufacturers, making the information easy to incorporate into an existing course. Special features are included that apply material to the service training field and photos and illustrations are ample throughout.
