Plug-in hybrid electric vehicle (PHEV) is a hybrid electric vehicle with a battery which can be recharged from an external power source (most commonly a charging station). Plug-in hybrid electric vehicle is a mix of a hybrid electric vehicle (HEV) and a plug-in electric vehicle. It combines an internal combustion engine (ICE) system with an electric motor. This means that it can be fueled with fossil fuels like a regular hybrid. It also has a charge-depleting mode which allows it to operate like a plug-in electric vehicle, using only electric power. When the power level in the battery depletes to a predetermined low, the vehicle switches to a mix mode where it operates like an HEV.
PHEVs have the potential to have even better fuel economy than HEVs since they use even less of its ICE, making it possible to use it more efficiently. The electric driving range of PHEVs is usually around 30 to 80 km (20 to 50 miles). Because of this, PHEVs are a great and environmentally friendly option for people whose daily driving range is somewhere between 30 to 80 km, but who still sometimes need to cover long distances.
