What is a Hybrid?
The dictionary defines a hybrid as something
of mixed origin.
Any vehicle that combines two or moresources of power that can directly or indirectly
provide propulsion power is a hybrid.
Hybrid electric vehicles (HEVs) include both a
combustion engine as well as an electric
motor.

PARALLEL HYBRID
Gasoline engine and electric motor worktogetherto move the car forward.
Has a fuel tank that supplies fuel to the engine
like a regular car. It also has a set of batteries
that run an electric motor.
Both the engine and electricmotor can turn the transmis-
sion at the same time.

SERIES HYBRID
Gasoline engine either directly powers anelectric motor that powers the vehicle, orcharges batteries that will power the motor.
The fuel tank goes to the engine, but theengine turns a generator.
Then the generator can either charge the
batteries or power an electric motor thatdrives the transmission.
The engine does not directly power the car.

HOWDO HYBRIDCARSWORK
A hybrid car is a passenger vehicle that is
driven by a hybrid engine, which is an engine
that combines two or more sources of power,
generally gasoline and electricity

Working Continued
Both use gasoline-electric hybrid technology,
but in radically different ways
Both have small gasoline engines
Both produce much less pollution than
standard gasoline cars
Both are constructed of ultra lightweightmaterials like carbon fiber or aluminum to
overcome the power gap

Working Continued
Both are generally designed to be moreaerodynamic than most cars, allowing them toslice through the air instead of pushing it out of
the way Both use a process called regenerative braking to
store the kinetic energy generated by brake use inthe batteries, which in turn will power the
electric motor Both use electric power at starts and stops, low
speeds (generally below 15mph)

Why Hybrid Vehicles?
Emissions from recent CVs causes GlobalWarming and Human Sickness.
Advances in battery, power electronics
technologies have made commercializationpossible
Performance is generally as good as or betterthan CVs

pollution. HEVs have demonstrated significant potential to
reduce fuel consumption and exhaust emissions.
