This book discusses the principle and control technology of regenerative braking system of electric vehicles. It is an academic monograph in the field of electric vehicles. It is condensed from the independent research results produced by the author team in the field of more than ten years of close cooperation between enterprises, universities and research institutes. This book describes the scheme design, control, test and evaluation technology of regenerative braking system with a relatively strict structure system. It is mainly aimed at engineers, researchers, teachers and students in the field of electric vehicles and brake technology, such as electric vehicle enterprises, brake parts enterprises, automotive research institutes, automotive colleges and universities.The basis of English translation of this book, originally in Chinese, was facilitated by artificial intelligence. The content was later revised by the author for accuracy.
