Electric and Hybrid-Electric vehicles offer the most promising options for reducing vehicular emissions and increasing vehicle fuel efficiency.  Electric vehicles (EVs) constitute a group of automobiles which qualify as ZEV.  These vehicles use an electric machine for propulsion, and batteries as electrical energy storage devices.  However, since the energy storage capacity of batteries is rather limited, these vehicles suffer from a limited driving range.  Hybrid-Electric vehicles on the other hand, qualify as Ultra Low Emission Vehicles (ULEVs), and do not suffer from the range limitations imposed by EVs.  These vehicles combine more than one energy source to propel the automobile.  In heat engine/battery hybrid systems, the mechanical power available from the heat engine is combined with the electrical energy, stored in a battery to propel the vehicle.  These systems also require an electric drive train to convert electrical energy into mechanical energy, just like their EV counterparts.

This talk will touch on the following topics:

            Overview of EV/HEV Power Train

            Vehicle performance and dynamics

            Available and potentially available energy and power sources for vehicle application        

            Energy conversion (energy converters)

            Characteristics of ICE powered vehicles and battery powered electric vehicles

            Regenerative braking

            Examples of electric and hybrid drive train technologies being developed in my group at Texas A&M University.
