Energy Efficiency of Hybrid and Electric Vehicles, Labs

 Average 0 out of 5

The goal of this course is to provide analytical and hands-on skills on defining and and testing power losses in powertrain systems of electric vehicles (EV) and hybrid-electric vehicles (HEV).

Description:

This resource contains a course developed by University of Alabama at Birmingham through seed funding from the Center for Advanced Automotive Technology (CAAT).

The goal of this course is to provide analytical and hands-on skills on defining and testing power losses in powertrain systems of electric vehicles (EV) and hybrid-electric vehicles (HEV).

The course contains introductory lectures to present power losses and energy efficiency in EV and HEV. Laboratory experiments and computer workshops, the main portion of the course, follow the lectures. The laboratory test modules are built with the use of hardware and tests including ordinary and planetary gear sets, gear power loss test rig, electric motors, two unmanned ground vehicles with individual wheel drives (3-wheeler and 4-wheeler), etc. National Instruments LabVIEW and myRIO are in use for practical laboratory work. Computer workshops facilitate the understanding of HE concepts and operational modes and develop skills in simulating vehicle characteristics.
