Any vehicle that combines two or more sources
of power that can directly or indirectly provide
propulsion power is a hybrid.
Trains ---Diesel-Electric Hybrid
Cars & SUVs- Gasoline- Electric Hybrid
Submarines- Nuclear –Electric,Diesel-Electric
Hybrid electric vehicles ("HEVs") = Internal
combustion engine + electric motor powered by
Commonly Mistaken with Electric Vehicle.
Less fuel than traditional counterparts and without
Same as driving any other conventional vehicle.
We all have owned a hybrid Vehicle at sometime.
Gas-powered car Electric-powered car
It has a fuel tank, which
supplies gasoline to the engine.
The engine then turns
a transmission, which turns the
On the other hand, it has a set
of batteries that provides
electricity to an electric motor.
The motor turns a transmission,
and then it turns the wheels.
Advantages over vehicles
with internal combustion
EVs do, however, face
Bulk & weight:
Pollution caused by conventional cars
Increasing prices of fuel day by day
Fuel is a limited natural source
In fact, gasoline-fueled HEVs are among a
select few vehicle technologies that can
dramatically increase fuel economy, while
reducing pollution and delivering top safety
Electric Motor Drive/Assist
Use low-rolling resistance tires
Use lightweight materials
SERIES HYBRID VEHICLE
PARALLEL HYBRID VEHICLE
SERIES PARALLEL HYBRID VEHICLE
Chevrolet Volt –Series Hybrid
Ford Escape–Series Parallel Hybrid
Honda Insight–Parallel Hybrid
Simplest hybrid configuration.
Electric motor is the only means of providing power .
Engine size is smaller
The battery pack more powerful .
Series hybrids more expensive .
Engine in a series hybrid is not coupled to the wheels.
Series drivetrains perform best in stop-and-go driving .

At low speeds is
powered only by
the electric motor
Both the engine and the electric motor
generate the power that drives the wheels.
Smaller battery pack.
Engine is connected directly to the wheels.
Quite efficient on the highway.
Operates inefficiently in stop-and-go driving.
Merges the advantages and complications of the parallel and
Engine can both drive the wheels directly and be effectively
disconnected from the wheels .
The Toyota Prius ,new Ford Escape Hybrid.
Engine operates at near optimum efficiency more often.
This system incurs higher costs than a pure parallel hybrid.
It needs a generator, a larger battery pack, and more
computing power to control the dual system
It has potential to perform better.
You can get the best mileage from a hybrid
car by using the same kind of driving habits
that give you better mileage in your gasoline-engine
Maintain a constant speed
Avoid abrupt stops
Use less oil than ICE
Emit less CO2 than ICE
Fuel efficiency increased
Less overall mass
Battery level efficiency
Battery capacity reduces by time, even you do not use it.
This will impact fuel economy
Fuel economy is dependant
on battery capacity
The Honda Insight’s battery pack
120 Panasonic 1.2-volt cells (total 144 V)
Nickel metal hydride
100A discharge, and 50A charge rates
The system limits the usable capacity to 4ah to
extend battery life
Time of battery changing is long
Batteries are heavy (100kg extra weight consumes 2L/100km more)
Batteries are expensive
Low performance in hot or cold temperatures also may damage the
Very sensitive to overcharge/undercharge(Battery life reduces
Contain toxic heavy metals, disposal issue
Opportunity for researchers:
Advance research projects on batteries are supported by governments
Currently more expensive than conventional
Heavier than conventional, due to battery pack and electric motors
Limited battery life
Expensive battery pack if you want to replace it
Safety issues, high voltage battery and fuel
Reliability, still under study,
More complex computer controlled systems
May have drivability issues
Expensive to repair
