MOVES does not separately model hybrids/plug-in hybrids with a conventional gas or diesel engine. These vehicles meet the same emissions standards as conventional gasoline or diesel vehicles and are incorporated into the fleet average emissions for each model year in MOVES.
You can model the impacts of changing fractions of fully electric passenger cars (sourceTypeID=21), passenger trucks (31), and light commercial trucks (32) using the AVFT input table in MOVES. You can access this table using the Fuel tab in the MOVES Data Importer (National Scale), or the County Data Manager (County Scale), or the Project Data Manager (Project Scale). Which scale you should choose depends on what type of analysis you are doing. You can find more details on different scales in MOVES as well as how to use the AVFT table in the MOVES2014a Hands-On Training Course materials available at:
Note that MOVES does not account for emissions from generation of electricity when modeling electric vehicles or plug-in hybrids. It assumes fully electric vehicles have no tailpipe or evaporative emissions and that brake and tire wear emissions are identical to conventional vehicles. By default, MOVES assumes there are no fully electric vehicles in the fleet.
