what is phev

A PHEV, or plug-in hybrid electric vehicle, is a type of hybrid electric vehicle that can be charged by plugging a charging cable into an external electric power source, in addition to being charged internally by its on-board internal combustion engine-powered generator. PHEVs use batteries to power an electric motor and another fuel, such as gasoline, to power an internal combustion engine. The batteries in PHEVs can be charged using a wall outlet or charging equipment, by the internal combustion engine, or through regenerative braking. PHEVs are similar to all-electric vehicles in that they displace greenhouse gas emissions from the car tailpipe exhaust to the power station generators powering the electricity grid. Compared to conventional hybrid electric vehicles, PHEVs have a larger battery pack that can be charged. PHEVs are often called plug-in hybrid electric vehicles.
