HYBRID VEHICLES

A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle

Fusion between an internal combustion engine (ICE) and electric motor—achieving different functions through different power combinati ons

WHY HEV ?Regenerative braking actually makes city

driving more economical than on the highway.Fuel efficiency is greatly increased (twice).Emissions(heating) are greatly decreased.Dependency on fossils fuels can be

decreased. Can be run on alternative fuels as well.

Global-Warming: Still An Issue(word temprature)

Hybrids are not zero-emission(heating) vehicles.

Will cut down emissions of global-warming pollutants by a third to a half.

HEV MODEL & componunts

HOW HYBRIDS ELECTRICAL

VEHICLE (HEV) WORK?

CAR STARTS

BATTERY SUPPLY

About HEVsHEVs offer the efficiency of electric-powered vehicles

without having to recharge by using conventional engines and fuels.

Efficiencies are gained from motor down-sizing and regenerative braking.

Inherent flexibility allows use for run multiple applications

How much would the car cost to maintain and manufacture?

Maintenance: air filter change, change the battery about every 64,380 kilometres.

Oil changes about 8,050-16,093 kilometres

Very similar cost to other normal carsOffer less maintenance than ordinary cars

CLASSIFICATIONSParallel Hybrids

Series Hybrids

Power-split Hybrids

Parrallel hybrid SyatemIn a parallel hybrid system, both the engine and the

electric motor drive the wheels, and the drive power from these two sources can be utilized according to the prevailing conditions.

because the power flows to the wheels in parallel. In this system, the battery is charged by switching the electric motor to act as a generator, and the electricity from the battery is used to drive the wheels.

Although it has a simple structure, the parallel hybrid system cannot drive the wheels from the electric motor while simultaneously charging the battery since the system has only one motor

Serial Hybrid SystemThe engine drives a genertor & an electric

motor use this generated electicity to drive the whill

Because power flows in the whill in series I,e, the engine power & the motor power are in series

It can supply electicity to the electric motor & efficiently charge the battery

PARALLEL & SERIES HYBRIDS

Advantages and disadvantages of hybrid cars?Advantages:Lower

emissions(heating) & better mileage

Reduce the dependency on fossil fuels

Money savedLow maintenanceBetter for environment

Disadvantages:High costMore weight due to

battery packsRisky in accidentsBatteries are non-

reusableDisposal of batteries.

POWER SPLIT HYBRIDS It combines both Series and Parallel HybridsSeries hybrids tend to be more efficient at

lower speeds and parallel tend to be more efficient at high speeds

Hence It is more efficient

POWER SPLIT HYBRIDSIt has two motors, and depending on the driving

conditions, uses only the electric motor or the driving power from both the electric motor and the engine, in order to achieve the highest efficiency level. Furthermore, when necessary, the system drives the wheels while simultaneously generating electricity using a generator.

This is the system used in the toyota Prius and the Estima Hybrid.

POWER SPLIT HYBRIDS

ADVANTAGESReduced fuel consumption(less Fuel Requered)

Excellent gas mileagr

Lighter batteries than electric vehicles

Regenerative braking system stores electrical energy in Batteries

Uses less fuel to recharge batteries

Ex, BMW Hybrid X5 & 3 sries Date- 17 feb 2016

CONCLUSIONSo, the HEVs have more efficiency, Low Fuel

Economy, High Reliability and Less Air Pollution.

Optimum Utilisation of these Vehicles will yield in good Results, especially Reduction of pollution.
