2. Introduction A hybrid electric vehicle (HEV) augments an electric vehicle (EV) with a second source of power referred to as the alternative power unit (APU). A hybrid can achieve the cruising range and performance advantages of conventional vehicles with the low-noise, low-exhaust emissions, and energy independence benefits of electric vehicles 2

3. WHAT IS A HYBRID? The dictionary defines a hybrid as something of mixed origin A hybrid is a vehicle that is propelled by two power sources. Internal combustion engine (ICE) + Electric motor powered by batteries. 3

4. 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 There are two types of gasoline-electric hybrids: Parallel hybrid Series hybrid HOW DO HYBRID CARS WORK?

5. Gasoline engine and electric motor work together to move the car forward HOW PARALLEL HYBRID CARS WORK

6. Gasoline engine either directly powers an electric motor that powers the vehicle, or charges batteries that will power the battery HOW SERIES HYBRID CARS WORK

7. LEVELS OF HYBRID VEHICLES 7 Full hybrid They feature idle-stop function Regenerative braking Most are capable of using the electric motor alone to propel the vehicle The electric motor also assists the engine Battery voltages are about 200 to 300 volts (For Example:- Toyota Prius)

8. LEVELS OF HYBRID VEHICLES 8 Medium hybrid They feature idle-stop function Regenerative braking Most are not capable of using the electric motor alone to propel the vehicle The electric motor usually assists the engine Battery voltages are about 144 to 158 volts (for Example : Honda Civic Hybrid.)

9. LEVELS OF HYBRID VEHICLES 9 Mild Hybrid They feature idle-stop function Regenerative braking Are not capable of using the electric motor to propel the vehicle These systems are usually 42 volts or less (For Example : The Micro Hybrid SCORPIO)

12. We are all familiar with  gasoline-powered cars , and most people have heard about or seen  electric cars . A hybrid car is a combination of the two. A hybrid vehicle contains parts of both gasoline and electric vehicles in an attempt to get the best of both worlds. In a traditional hybrid vehicle, you have a complete electric car. It includes an  electric motor  to provide all of the power to the wheels, as well as  batteries  to supply the motor with electricity. Then you have a completely separate  gasoline engine  powering a generator. The engine is very small -- perhaps 10 to 20 horsepower -- and it is designed to run at just one speed for maximum efficiency. The purpose of this small, efficient engine is to provide enough power for the car at its cruising speed. During times of acceleration, the batteries provide the extra power necessary. When the car is decelerating or standing still, the batteries recharge. This sort of hybrid car is essentially an electric car with a built-in recharger for longer range. The advantage is that the small, efficient gasoline engine gets great mileage. Working of hybrid Cars

13. ARE HYBRID VEHICLES SAFE? The following will disable the high voltage system High voltage interlock circuit Airbag deployment High voltage leak Removing battery negative 14

14. WHAT HAPPENS IF A HYBRID VEHICLE IS SUBMERGED IN WATER? There is no risk of electric shock from touching the car's body or framework—in or out of the water. 15

15. Better mileage Improved acceleration (most of the time) Less dependence on fossil fuels Lower emissions Some states provide incentives for driving a hybrid (In USA) Great driving experience 16 HYBRID VEHICLE VS REGULAR VEHICLE Little highway mileage increase High initial cost Needs high fuel cost to be worthwhile Could cost more to repair Extra maintenance items Some hybrids need special tires Advantages Disadvantages

16. Quickest and easiest way for emergency responders : All hybrid vehicles have badge plates located on the sides and/or rear of the vehicle HOW TO IDENTIFY A HYBRID VEHICLE

17. HOW TO IDENTIFY A HYBRID VEHICLE In place of a tachometer, a power meter showing kW output is used Do you notice orange (high voltage) or blue (intermediate voltage) loom under hood or running under vehicle? Hybrid tag on motor Auxiliary Power Output Operation button on dash or 120VAC plugs noted in bed of pickup

18. Hybrid concept car THE FUTURE OF HYBRID CAR TECHNOLOGY

19. 20 CONCLUSIONS Using the concept of Hybridization of cars results in better efficiency and also saves a lot of fuel in today’s fuel deficit world. A hybrid gives a solution to all the problems to some extent. If proper research and development is done in this field, hybrid vehicle promises a practical, efficient, low pollution vehicle for the coming era.
