2. CONTENTS:-
 Definition.
 What is Hybrid?
 Classification.
 Electric verses Internal Combustion.
 Timeline of Hybrid technology.
 The Batteries.
 The Future scope.

3. HYBRID VEHICLE:-
 A Hybrid vehicle is one that uses two different
methods to propel the vehicle.
 A Hybrid Electric Vehicle, abbreviated HEV uses
both an internal combustion engine and an electric
motor to propel the vehicle.
 The hybrid vehicles use a high voltage battery pack
and a combination electric motor and generator to
help or assist a gasoline engine.

4. What is a Hybrid?
 Hybrid electric vehicles include both combustion
engine as well as electric motor.
 If we had better batteries, we would not need
hybrids at all.
 Hybrid can be implemented in many kinds of
vehicles.

5. Global Warming:-
 Hybrids are not zero-emission vehicles.
 Will cut down the emissions of global-warming.
 Later models may cut these emissions down by even
more.

6. Why Hybrid?
 Regenerative braking actually makes city driving
more economical than on the highway.
 Fuel efficiency is greatly increased.
 Emissions are greatly decreased.
 Dependency on fossil fuels can be decreased.
 Hybrids can be run on alternative fuels as well.
 New materials can be implemented.

7. CLASSIFICATION:-
The types of hybrid electric vehicles include:
1. Series Hybrid electric vehicle.
2. Parallel Hybrid electric vehicle.
3. Series-Parallel Hybrid electric vehicle.

12. Batteries:-
 NiMH D cells
 Prismatic Ni-MH
 Metal case Prismatic Ni-MH

13. Electric control unit:-
 Regulates
temperature and
state of charge.
 Ensures safe and
reliable driving.

14. History:-
 1839 : First electric vehicle.
 1890-1910: Significant improvements in battery
technology(Pb,NiFe)
 1898:Ferdinand Porsche built a hybrid.
 1905: Gas – Electric car.
 1991:Advanced super Battery.
 2000:Toyota prius available in Japan and US.
 2002:Honda civic Hybrid introduced
 2004:Toyota prius 2 introduced

15. Components of HEVs:-
1)Hybrid engine:-

16. 2). Hybrid Battery:-

17. 3). Electric motor:-

18. 4).Generator:-

19. 5). Transmission and gearing:-
 Input-split mode
Compound-split mode

20. Advance technology in HEVs
 Regenerative braking.
 Automatic start and shut off.
 Use advanced aerodynamics to reduce drag

21. Advantages:-
Mechanical.
Environmental.
Energy efficiency.
Cost of recharge is very low.
Use less fuel used to recharge battery.
Lighter.
Regenerative braking system stores electrical energy
in batteries.

22. Disadvantages:-
High cost.
Risk of exposure to high voltage wires.
Long time batteries charging.
More expensive than conventional vehicles.
Spare part maybe hard and costly.

23. Future scope:-
When the entire world is facing the scarcity of petrol
and the gasoline prices are touching the sky, Hybrid
Cars have come up as a promising and a feasible
option to cope with the situation.
The use of hybrids is being encouraged by many
governments in the world.

24. Conclusion:-
 A technology exists to build a future with a
significant lower dependence on oil.
 Hybrids can play an important role in realizing this
future, filling the gap between immediate
improvements through conventional technology.
 Hybrids can help drive passengers vehicle oil
consumption and global warming.
