3. INTRODUCTION :
 The term hybrid vehicles in general usage refers to
vehicles with two or three different types of sources
delivering power to the wheels for propulsion.
 A hybrid electric vehicle (HEV) is a type of hybrid
vehicle that combines a conventional internal
combustion engine (ICE) system with an electric
propulsion system (hybrid vehicle drivetrain).
 In practical we all have won a hybrid vehicle (i.e moped).

4. HISTORY :
 William H. Patton filed a patent application for a
gasoline-electric hybrid rail-car propulsion system in early
1889, and for a similar hybrid boat propulsion system in
mid 1889.
 In 1896, the Armstrong Phaeton was developed by
Harry E. Dey and built by the Armstrong Company of
Bridgeport.
 In 1900, while employed at Lohner Coach Factory,
Ferdinand Porsche developed the Mixte.

5. DESIGN :

6. TYPES OF HEVs :
Based on the path of energy flow :
 Mechanical Power Transmission Path(MPTP).
 Electrical Power Transmission Path(EPTP).
 Combination of MPTP and EPTP.
Based on architecture :
 Series.
 Parallel.
 Series-parallel.

7. MECHANICAL POWER TRANSMISSION PATH(MPTP) :
 The energy flow in a vehicle starts from source of
energy and ends at wheels with the delivery of
propulsion power known as power transmission.

8. ELECTICAL POWER TRANSMISSION PATH(EPTP) :
 In electric vehicle power transmission power transmission
is almost electrical except for coupling devices between
electric motors and wheels. The coupling device can
simply be a gear to match the electric machine speed to
vehicle speed.

9. COMBINATION OF MPTP AND EPTP :
 The propulsion power is transmitted to wheels through
either MPTP or EPTP or combination of both.

10. SERIES HEVs :
 A series hybrid is one in which only one energy converter
can provide propulsion power.
 Only electrical motor provides all propulsion power to
wheels.

11. PARALLEL HEVs :
 The IC engine and electric motor are configured in parallel with a
mechanical coupling.
 The power requirements of electric motors is lower than that of series
HEV.

12. SERIES-PARALLEL HEVs :
 It combines the benefits of series and parallel hybrid architectures
providing high output power.
 The power-split device divides the output from the engine into
mechanical and electrical transmission paths.
 Even IC engine is also used to charge the battery.

13. LIST OF HEVs :
 Motorcycles
 Automobiles and light trucks
 High-performance cars
 Formula 1
 Taxis
 Buses
 Trucks
 Military vehicles
 Locomotives
 Marine and other aquatic
 Aircraft

14. COMMERCIAL VEHICLES :
 Toyota Prius
 Toyota Highlander
 Ford Escape
 Mercury Mariner
 Honda Insight
 Honda Civic HEV

15. ADVANTAGES OF HEVs :
 Environment friendly
 Financial benefits
 Less dependence on fossil fuels
 Regenerative braking system
 Built from lighter materials

16. DISADVANTAGES OF HEVs :
 Less power
 Expensive
 Poor Handling
 High maintenance cost
 Presence of high voltage in batteries

17. CONCLUSION :
 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.
