Hybrid Electric Vehicle (HEV) models currently populating the vehicle electrification landscape indicate their dominance in the market. Although electric, plug-in, and fuel cell vehicles are making inroads in the market, the HEV stands as the market leader in adoption, and manufacturers have no plans on diminishing HEV production.

HEV powertrain operation is totally different from the traditional vehicle. It is essential to understand the various operating modes and how failure modes in the hybrid system affect its operation. Scan tool data, animations, and detailed graphics are used for teaching how these systems operate and how different diagnostic approaches are required.

Course Objectives

By participating in this On Demand Course, you will be able to:

  • List the advantages and disadvantages of HEV systems
  • List the major systems contained in an HEV system
  • Describe the architectures of the major HEV system designs
  • List the common components found in HEV systems
  • Identify HEV Powertrain component configurations
  • Describe the operation of the HEV system during the four basic operating modes
  • Describe the operation of an HEV Planetary Gear Set during a basic drive cycle

Course Outline

Part 1:  Hybrid Electric Vehicle System Components & Locations

  • Hybrid Technology
  • Hybrid Technology:  Fuel Economy & Emissions
