ABSTRACT
In this book, EHVs stands for electric hybrid vehicles. EHV constitutes an aggressive novel technology aimed at improving comfort, gas mileage, and environmental performance of road vehicles [1,2].
The degree of “electrification” in a vehicle may be defined by the electric fraction, %
E
[3]:
(7.1)
For a mild hybrid car with battery soft-replenishing %
E
is lower than 40% in town driving. It may reach up to 70% when the battery is replenished from the power grid daily. %
E
becomes 100% for fully electric vehicles, with fuel cells or batteries or inertial batteries (flywheels) as the energy storage system.
