WHAT IS A HYBRID VEHICLE?

Any vehicle which combines two or more sources of power.

Examples:Diesel – electricNuclear – electricGasoline - electric

HYBRID STRUCTUREThe two power sources found in hybrid vehicles may be combined in different

ways, either in parallel or series

4

PARALLEL HYBRID• Gasoline motor• Batteries which powers

an electric motor• Both can power the

transmission at the same time

• Electric motor supplements the gasoline engine

5

SERIES HYBRID• Gasoline motor turns a

generator• Generator may either

charge the batteries or power an electric motor that drives the transmission

• At low speeds is powered only by the electric motor

COMMON MEANS OF IDENTIFICATION

Motives for Hybrid Vehicles• Overcome energy storage (range) and

power (fuel rate) problems.• Good designs yield double the fuel

economy.• In principle, it might be possible to triple the

fuel economy.• The overall efficiency is similar to thermal

electric power plants.• Exhaust emission management is

simplified.

ADVANTAGES OF HYBRID CAR

* ENVIRONMENT FRIENDLY:- RUNS ON TWIN POWERED ENGINE THAT CUTS FUEL CONSUMPTION AND CONSERVE ENERGY.

*LESS DEPENDENCE ON FOSSIL FUELS:-IT IS MUCH CLEANER AND REQUIRES LESS FUEL TO RUN.

*BUILT FROM LIGHT MATERIALS:- MADE UP OF LIGHT MATERIALS WHICH MEANS LESS ENERGY.

*REGENERATIVE BRAKING SYSTEM:- EACH TIME YOU APPLY BRAKE WHILE DRIVING HELPS YOU TO RECHARGE YOUR BATTERY A LITTLE.

DISADVANTAGES*LESS POWER

*CAN BE EXPENSIVE*POORER HANDLING

*HIGHER MAINTENANCE COSTS
