Plug-in Hybrid Vehicles - Definition, Glossary, Details - OilgaeA plug-in hybrid electric vehicle (PHEV) is a hybrid vehicle with batteries that can be recharged by connecting a plug to an electric power source. It shares the characteristics of both conventional hybrid electric vehicles and battery electric vehicles, having an internal combustion engine and batteries for power. Most PHEVs on the road today are passenger cars, but there are also PHEV versions of commercial passenger vans, utility trucks, school buses, motorcycles, scooters, and military vehicles. PHEVs are sometimes called grid-connected hybrids, gas-optional hybrids, or GO-HEVs - SourcePlug-in hybrids are just what they sound like: a gasoline-engine hybrid vehicle that has a battery that can be plugged in for recharging. They are being designed to handle a commuter-type range (20 to 60 miles) on just their electric charge, with the internal combustion engine providing valuable backup. Plug-in hybrids will help to provide a stepping-stone for folks who aren’t able to utilize all-electric cars due to their shortened range.
