Vehicles using both electric motors and internal combustion engines are examples of
hybrid electric vehicles, and are not considered pure or all-electric vehicles because they cannot be externally charged (operate in charge-sustaining mode) and instead they are continually recharged with power from the
internal combustion engine and
Hybrid vehicles with batteries that can be charged externally to displace some or all of their internal combustion engine power and
gasoline fuel are called
plug-in hybrid electric vehicles (PHEV), and run as BEVs during their
charge-depleting mode. PHEVs with a
powertrain are also called range-extended electric vehicles (REEVs), such as the
Chevrolet Volt and
Plug-in electric vehicles (PEVs) are a subcategory of
electric vehicles that includes battery electric vehicles (BEVs), plug-in hybrid vehicles, (PHEVs), and
electric vehicle conversions of hybrid electric vehicles and conventional
internal combustion engine vehicles.
In China, plug-in electric vehicles, together with hybrid electric vehicles are called new energy vehicles (NEVs).
 However, in the United States,
neighborhood electric vehicles (NEVs) are battery electric vehicles that are legally limited to roads with posted speed limits no higher than 45 miles per hour (72 km/h), are usually built to have a top speed of 30 miles per hour (48 km/h), and have a maximum loaded weight of 3,000 lbs.
