An Overview of Hybrid Electric Vehicle (HEV) Technologies

 Average 0 out of 5

A PowerPoint presentation and lab that provide a general overview of HEVs and the technologies powering them. This resource was developed through seed funding from the CAAT.

Description:

This PowerPoint presentation and lab provide a general overview of HEVs and the technologies powering them. Both were developed to enhance automotive courses with HEV technologies through seed funding from the CAAT. The included slides reflect these changes made for HEV technologies. There are two areas of focus:

  1. Theory of operation  
  2. 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  
  • 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.
