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 to as Battery Electric Vehicles
(BEVs). The second category of PEVs, which is more commercialized than the
EVs, is the Plug in Hybrid Electric Vehicles (PHEVs) where the role of energy
storage is to supplement the power produced by the IC engine.
