Any vehicle that uses two or more distinct powersources is a Hybrid Vehicle.

The term most commonly refers to a hybrid electricvehicle, which combines an IC engine and an electric

motor to drive the Vehicle.

The era of Hybrid vehicles started a decade ago, butstill, it has to go further.

Different Power Sources-Diesel+ElectricGasoline+ElectricGasoline+Diesel+Electric

et cetera.

Rail-Transports-

In the U.S., General Electric introduced a prototype rail enginewith their "Ecomagination" technology. They store energy in alarge set of sodium nickel chloride (Na-NiCl2) batteries tocapture and store energy which is dissipated during dynamicbraking. There is at least a 10% reduction in fuel use with this

system.

Aircrafts-

In 2013, the Boeing 737NG will also be launched as a HybridAircraft which uses Electric Energy for all the movements onground and to provide more power during take-off andclimb, whereas the Engines will work on flight, take-off andlanding only.

Road transport and Commercial Vehicles-

Since hybrid technology is fuel efficient, the transportationcost will be reduced. Hence, Hybrid technology is beingmade common in many buses and trucks.

Cars-o Here are some On-Road hybrid cars-

Honda Civic Hybrid, Honda Insight, Honda CR-Z,Honda Accord Hybrid, Mercedes Benz S400 , BMW 7-

Series hybrids, Toyota Prius, Ford Escape, Ford Fusion,Lexus RX400h, RX450h, GS450h, LS600h and CT200h.

All Hybrids have-

An IC Engine (usually Gasoline is used as fuel)

Nickel-Metal Hydride Batteries (NiMH; usually144V,6Ah)

An Electric Motor (also acts as Generator)

Regenerative Braking System (which, while Braking,converts the K.E. of the vehicle into the ElectricEnergy which is stored in batteriesand used to run the Electric Motor.)

The two power sources can be assembled in twoways- either in Parallel or in Series.

When both the sources (IC Engine & Electric Motor)

provide power to the drivetrain, then its ParallelHybrid.

When only one source(electric motor) provides powerto the drivetrain and the other (IC Engine) is required

just to run the Motor and for the charging ofbatteries at times but not to provide power directly tothe drivetrain, then its Series Hybrid.

o It can be seen inthe picture thatboth, the ElectricMotor and the ICEngine are directly

providing power todrive the vehicle.

o The IC Engine also

charges the batteries,using Electric Motor asa Generator. o The Regenerative Braking System

also charges the batteries whenbrakes are applied.


9/15

o It can be seen inthe picture that,

the IC Engine iscoupled with aGenerator to run the

motor and to chargethe batteries but notto drive the vehicle.

o

Only the Electricmotor drives thevehicle. o The Regenerative Braking System

also charges the batteries whenbrakes are applied.

To be more specific, lets see the configuration andspecifications of the successful Hybrid-Honda Civic.o The Civic hybrid was first introduced in Japan at

the end of 2001 and ranks as the second bestselling electric hybrid car in the U.S.

11/15

Type- Parallel Hybrid. Engine- In-line 4-cylinder; 1497CC.

Battery- Li-ion; 144 V; 20kW.

Motor- Permanent Magnet Assist; 15kW;hp@rpm= 23@1546-3000.

Transmission- Continuously VariableTransmission (CVT).

Brakes- Regenerative Brakes.

When compared to a gasoline engine Civic with an automatictransmission, the Civic hybrid provides an increase of fueleconomy in city driving of about 63 percent and an increase offuel economy in highway driving of about 27 percent.


12/15

Savings at the Pump.Since, fuel prices are hiking with the speed of achain reaction now-a-days, and all Hybrids geta better fuel economy than their gasoline

counterparts.

Lower Emissions, Lesser Pollution as lessCarbon Monoxide is being added to theEnvironment which prevents Global Warming.Hence, its eco-friendly.


13/15

General Maintenance and Repair Cost is quitehigher.

Expensive new Batteries. Batteries need to bechanged out in every 8 to 10 years.

Higher Depreciation Rate of vehicle.

Higher Prices of Vehicles.

Hence, not efficient forpockets.


14/15

Based on hard evidences, the hybrid vehiclesare at least as reliable as a standard car withmore than twice the fuel economy.

Hybrid Vehicles are fuel-efficient but notefficient for pockets.

To encourage this eco-friendly drive, wemust work to lessen its problems such as

high costs as its benefits are all that we need.
