An Overview of Hybrid Electric Vehicle (HEV) Technologies

This PowerPoint presentation and lab provide a general overview of Hybrid Electric Vehicles (HEVs) and the technologies powering them. Both were developed to enhance automotive courses with HEV technologies through seed funding from the Center for Advanced Automotive Technology (CAAT). The included slides reflect these changes made for HEV technologies. This resource has two areas of focus: HEV theory of operation and safety and service procedures.

The following subjects are discussed: Types of HEV systems (Ex: parallel, series, and series-parallel), safety when working with HEVs (Ex: isolating systems/disable high voltage circuits, high voltage gloves, and insulated tools), testing HEV components (Ex: insulation tests), differences between similar components of standard vehicles and HEV (Ex: intake, motor and transaxle integration), power steering, regenerative braking, and correct service procedures for HEV components (Ex: battery, jump start, multimeter use, and oil change). Differences between types of hybrid systems are compared for the Chevy Volt, Ford Escape Hybrid, and Toyota Prius. After viewing this presentation, a technician should have a basic understanding of HEVs and their differences from traditional vehicles when servicing.

A Syllabus for Lewis and Clark Community College's AUTO 279 Advanced Engine Performance is also included, as it uses the presentation and lab activity. 

Below is a list of the files attached. The size of each file is included in parenthesis.
