Definitions
HEV Hybrid Electric Vehicle
A vehicle that has both an internal combustion
engine (ICE) and electric motor(s).
PHEV
Plug-In Hybrid Electric Vehicle
A vehicle that has both an ICE and electric
motors, and can recharge its batteries to full
charge from an external electric power source.
EV
Electric Vehicle
A vehicle which uses only electric motor(s)
for propulsion.

Terminology
From this point on in the course, we will refer
to all types of Hybrids and Plug-in Hybrids
collectively as P/HEVs.
In some instances, they may need to be
referenced separately, in which case, they will
be referred to as Hybrid (HEV) or Plug-In
Hybrid (PHEV) respectively.
Electric Vehicles will be referred to as EVs.
