Accelerated Lifetime Testing and Reliability Engineering for Electric Automotive Powertrains

This book provides an application-driven grounding in the fundamentals of accelerated lifetime testing (ALT) and reliability validation for electric vehicle powertrains, unifying the full chain including usage definition, damage models, planning, and rigorous reliability statistics. It provides vital statistical and logical frameworks with a focus on validation for complex systems, covering basic experimental models, virtual validation, test economics, and much more. Following the introductory chapter, the book outlines usage definition, discussing usage space mixing, usage compression, sampling errors, and other variables such as ambient conditions, traffic, and road conditions. A chapter on damage models follows, covering mechanical, thermal, electrical, and chemical damage models, in addition to multi-stress models. This chapter leads into coverage of damage application, discussing different types of failure modes and their applications in transmission, e-motor, power electronic, and battery parts. Subsequent chapters cover validation techniques (duty cycle, high temperature operational endurance, combined stress, degradation), failure distributions, reliability validation, and game theory.
