A plug-in hybrid electric vehicle (PHEV), also called a plug-in hybrid vehicle (PHV) and a plug-in hybrid, is a hybrid electric vehicle that uses rechargeable batteries, or another energy storage device, that can be recharged by plugging it in to an external source of electric power, usually a normal wall socket). A PHEV shares the characteristics both of a conventional hybrid electric vehicle, having an electric motor and an internal combustion engine (ICE), and of an all-electric vehicle, having a plug to connect to the electrical grid. Most PHEVs are passenger cars; there are also PHEV versions of commercial vehicles and vans, utility trucks, buses, trains, motorcycles, scooters, and military vehicles.
