ABSTRACT
In this book, EHV stands for electric hybrid vehicle. 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]:
E P
P el=
+ =Peak electric power
Peak electric power peak ICE power el ICEP) ( )+ (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 (plug-in). %E becomes 100% for fully electric vehicles, with fuel cells or batteries or inertial batteries (flywheels) as the energy storage system.
