Hybrid and Electric Vehicle Systems

Hybrid Electric Vehicle (HEV), Plug-In Hybrid Electric Vehicle (PHEV), and Battery Electric Vehicle (BEV) technology model offerings and production volumes continue to accelerate with each model year. Advanced technology vehicle populations are significantly increasing throughout the world, making it vital for engineers, technicians, and educators to have a thorough understanding of these technologies and systems. This three-day practical and applications-based course will concentrate on architectures, operation, functions, and design considerations of the power electronics, energy systems, and failure modes associated with HEV and BEV vehicles, providing an environment in which participants can acquire a solid systems and integration foundation for applying this content to vehicle/systems design. Practical systems and circuit analyses with calculations will be used throughout the course.
