Battery Electric Vehicle, Plugin Hybrid Electric Vehicle, and the one I didn't know and had to look up.

Range extended electric vehicle (REEV) A battery-powered electric car with a smaller combustion engine that charges the traction battery through a generator. REEVs are different from plug-in hybrid vehicles (PHEVs) because REEVs have a larger battery and the engine only generates electricity to charge the battery.

They're acronyms.
