Plug in Electric Vehicles (PEVs) use energy storages usually in the form of battery
banks that are designed to be recharged using utility grid power. One category of
PEVs are Electric Vehicles (EVs) without an Internal-Combustion (IC) engine
where the energy stored in the battery bank is the only source of power to drive the
vehicle. These are also referred as Battery Electric Vehicles (BEVs). The second
category of PEVs, which is more commercialized than the EVs, is Plug in Hybrid
Electric Vehicles (PHEVs) where the role of the energy storage is to supplement the
power produced by the IC engine.
