Plug-In Electric Vehicles (PEV) are battery-powered electric vehicles
that draw their energy from the low-voltage grid. The term plug-in refers to the charging of the batteries, which takes place at a charging station into which the charging cable is plugged. There are two types of electric cars: those that are powered solely by electricity, which are Battery Electric Vehicles (BEV), and those that also have an internal combustion engine. These are called Plug-In Hybrid Electric Vehicles (PHEV).
