Hybrid Electric Vehicle

combines a conventional internal combustion

engine (ICE) propulsion system with an

electric propulsion system. i.e. it consists ofan internal combustion engine (ICE) with one

or more electric motors.

uses two or more distinct power sources to

move the vehicle.

Power sources for hybrid vehicles includefossil fuels, solar energy, wind energy, liquid

nitrogen, hydrogen or compressed natural

gas

History of HEVs

In 1899 Dr. Ferdinand Porsche ,an engineer

of Jacob Lohner & Co. invented first Hybrid

Electric Vehicle. The hybrid technology was mainly utilized

in developing diesel-electric submarines.

First modern hybrid electric car, the Toyota

Prius , was introduced in Japan in 1997

In India, the first HEV was launched by

Honda Motors Co. on June 18,2008.

COMPONENTS OF HEV

Components....

Power split device- Power split device is a gearboxthat hooks the gasoline engine, generator and electric

motor together

Internal combustion engine - an engine in whichcombustion of a fuel occurs with air in a combustion

chamber. The expansion of high-temperature and high

pressure gases produced by combustion apply direct

force to piston or some component which start moving,transforming chemical energy of fuel into useful

mechanical energy.

1. STARTING AND LOW

SPEED

For the initial

acceleration or low speed

driving, electric motor

uses the electricity from

the battery to power thevehicle

2.High SpeedDuring heavy

accelerating or

when additional

power is required,

the gasoline

engine and

electric motor

both are used topropel the vehicle

3.BRAKINGThe energy from

wheels turns the motor

in the reversedirection, converting

energy normally

wasted during breaking

into electricity, which

get stored in battery.

STOPPEDMany hybrid vehicles

conserve fuel by

incorporating an

automatic start shut-off system. When

vehicle is stopped

such as at red light,

gasoline engine shutoff automatically so

that fuel is not wasted

in idling.

Configurations

No mechanical

connection betweenengine and wheels,

only electrical motor

drives the wheels

series HEVs requiresmaller combustion

engine but heavier

battery packs than

parallel vehicles.

Series HEV

7/28/2019 Hybrid Electric vehicle.pptx

13/23

Parallel HEV

Both engine and

motor are directly

connected to wheels

Parallel hybrids are

more efficient than

series type because

both the engine and

motor can workindependently or

together.

Advantages It is believed the over one-third of carbon emissions

that are affecting our environment are produced by

vehicles. Hybrid vehicles can reduce these carbon

emissions by 50%.

Greater fuel efficiency and better mileage because

hybrids consume significantly less fuel thanconventional vehicles

Decrease our dependence on fossil fuels

Lighter engines because HEV engines can be sized

to accommodate average load, not peak load

Though we are using an IC engine of about 30-40%

efficiency, the motors and generators we use are

about 70-85% efficient .This may bring the overall

efficiency up to 50-70%.

TECHNOLOGIES

Regenerative Breaking

introduced by Erich Gaichen , German

inventor in 1931 It is still being used in modern hybrid

vehicles. This enhanced technology

recaptures energy lost through braking

and decelerating. This recaptured energy

is stored in a battery pack as electricity.

Plug-in Hybrid Electric Vehicles

Batteries can also be recharged by using an external

power source, such as a home electrical outlet

They travel some distance usually 10-40 miles on

electric motor. Then they run on engine . Even before

the battery is depleted, the gasoline engine may be

called on to provide additional power for recharging

the battery, accelerating or passing.

A PHEV 30, means the vehicle could travel 30 miles

on all-electric mode.

Batteries can recharge in just 3 hrs at 120V and 1.5

hrs at 240V.

Auto Expo 2012: Focus on

hybrid vehicles Peugeot ,French automobile manufacturer came to the

Expo for the first time with its hybrid car 3008

Volvo showcased a hybrid bus for the inter-city

transport segment

Volkswagen showcased its XL1 diesel hybrid concept

model at the event, which successfully attracted

majority of spectators because of its stylish looks also

Conclusion

Hybrid electric vehicles are not the only option formoving towards the green technology, but it may wellemerge as a serious candidate among the variousoptions.

Although basic technology has been developed great

deal of research work is needed to bring them forcommercialization. Research is being carried out forbetter batteries having low cost ,high energy densitiesand high life expectancy.

Basic infrastructure for running these vehicles and Govt.

support is also required.

Its true that hybrid electric vehicles are expensive but itsmuch smaller than the costs of global warming, climatechange.
