Course Description

The course is designed for the automotive technician who wants to gain greater knowledge in the practical management of electric vehicle systems. It is intended to give an in-depth look at the hybrid vehicle components including the Atkinson engine cycles, AC Induction & Permanent Magnet electric machine construction and operation, battery packs, power inverters, transaxles, and other electric propulsion systems. The hybrid technology is a natural pathway to comprehensive electric vehicle knowledge. Labs will include the use of vehicle scan tools to troubleshoot and the data will be entered into worksheets and analyzed.
