Just clearing up a bit of confusion here. This short list from the US DOE:
Here’s the List
All-Electric Vehicle (AEV)
A vehicle with plug-in capability; driving energy comes entirely from its battery.
Plug-in Hybrid Electric Vehicle (PHEV)
A vehicle with plug-in capability; driving energy can come from either its battery or a liquid fuel like gasoline, diesel, or biofuels.
Plug-in Electric Vehicle (PEV)
Any vehicle with plug-in capability. This includes AEVs and PHEVs.
Hybrid Electric Vehicle (HEV)
A vehicle that has an electric drive system and battery but does not have plug-in capability; driving energy comes only from liquid fuel.
Internal Combustion Engine (ICE) Vehicle
A vehicle for which driving energy comes only from liquid fuel.
