4.  A hybrid is a combination of two or more
things.
 In this case we mean a vehicle powered by
two different power Sources
 Electric motor/generator
 Internal combustion engine

6. NO!!!!!
 Hybrids existed in the late 1800’s
 Cars could be fuelled by either electricity or
ethanol
 No regenerative energy

8. The answer is :
Technology
&
Cost
But
The invention of the IGBT and other power
electronic advancements 1970 onwards has made
way for the modern hybrid electric vehicles.

11.  An electric propulsion system is comprised of
three main elements: power electronic
converter,
batteries , motor, and its controller
 DC Commutator Motor
 Permanent Magnet (PM) Brushless DC (BLDC)
Motor
 Switched Reluctance Motor ( SRM)
 Induction Motor


more economical.
Fuel efficiency is greatly increased (twice).
Emissions are greatly decreased.
Dependency on fossils fuels can be decreased.
Hybrids can be run on alternative fuels as well.

24.  Currently more expensive than conventional
 Heavier than conventional, due to battery pack


and electric motors weight
Limited battery life and expensive battery pack if
you want to replace it
More complex computer controlled systems
May have drivability issues
Expensive to repair

25.  More efficient diesel hybrids
 Plug in hybrids
 Fuel cell and plug in vehicles
 Powering your house/business with
your fuel cell/hybrid cars
 And more

 •Honda Civic Hybrid
 •Ford Escape Hybrid
 •GMC Silverado Hybrid
 •GMC Sierra Hybrid
 •Toyota Prius
 •Toyota Highlander Hybrid
 •Lexus 400h

27. According to the Business News on
12thApril, 2012, M&M is planning to Launch
a full Hybrid Electric Vehicles in India in a
couple of Years.

Soon can be seen on Indian Roads.

28. “Sometimes being different is good enough, you need not be
new all the time”
 So, the HEVs have more efficiency, Low Fuel
Economy, High Reliability and Less Air Pollution.
 Optimum Utilization of these Vehicles will yield in good
Results, especially Reduction of pollution.
 It can prove to be vehicle of future.
 If designed well, these hybrids can equal or better the
utility, comfort, performance and safety we’ve come to
expect, while saving us thousands of dollars at the gas
pump.
