3What is HEV…?
A hybrid car is any car that uses both electricity and fuel injection in order to run.

4History of HEV
1830’s• Battery electric vehicle invented by Thomas Davenport, Robert
Anderson, others - using non-rechargeable batteries. 1890’s
• EV’s outsold gas cars 10 to 1, Oldsmobile and Studebaker started as EV companies started as EV companies.
1904’s• Krieger Company builds first hybrid vehicle
1910’s• Mass-produced Ford cars undercut hand-built EV’s• EV’s persist as status symbols and utility vehicles until Great
Depression.

5Types of Hybridization
1. MILD / Micro Hybridization 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

6Types of Hybridization
2. Medium Hybridization 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

7Types of Hybridization
3. Full Hybridization 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

8Types of Hybrid
1. Series hybrid The fuel tank goes to the engine, but
the engine turns a generator. Then the generator can either
charge the batteries or power an electric motor that drives the transmission.
The gasoline engine does not directly power the car.

9Types of HEV
2. Parallel Hybrid Has a fuel tank that supplies gas to
the engine like a regular car. It also has a set of batteries that run
an electric motor. Both the engine and electric motor
can turn the transmission at the same time.

10Types of HEV
3. Series-Parallel Hybrid Series-Parallel type also called
Power-split hybrids. More beneficial then above hybrid. Most of the latest vehicle based on
this hybrid.

11Parts of HEV vehicle
1. Engine It’s much same as other vehicles
engine, but the size of hybrid electric vehicle engine is small and it’s more fuel efficient.
There are two types of engine, mostly used in HEV vehicle
a. Petrol Engineb. Diesel Engine

2. Battery It stores the energy generated from
gasoline engine or during regenerative braking, from the electric motor.
There are 3 types of batteries used in HEV vehicles
a. Lead Acid(2.2 volt)b. Nickel Cadmium (1.2 volt)c. Lithium-ion(3.7 volt)

3. Electrical Motor It’s power the vehicle at low speed
and assist the gasoline engine when additional power is needed.
Most of the electric machines used in hybrid vehicles are brushless DC motors (BLDC).

4. Controller The controller is used to charge the
battery or to supply the power to electric motor.
a. Converts Battery DC to a chopped DC power
b. Can chop in amplitude (DC) or frequency (AC)
c. Power is based on low voltage input signal 4-20 mA or 0-5V

5. Generator It converts mechanical energy from
engine into electrical energy, which can be used by electric motor stored in the battery. It’s also used to start the gasoline engine instantly.

17Disadvantages of HEV
Hybrids are more expensive than non-hybrids.
Hybrids (in regards to a car accident) have a much higher risk of exploding because it has a combination of gasoline and ethanol.
Sometimes they can be pretty ugly. Parts can be very expensive to
repair. (between $1,00,000 and $3,00,000 for a battery).
Slower than petrol powered cars.

18Future Scope
All the Major Automobile manufactures are working on Hybrid Electrical Vehicle.
Heavy vehicle like trucks will be use hybrid system in future. Efficiency of hybrid electric vehicle will further increase in future. Safety features will be add in new generation hybrid car or other
vehicle. Power of car have to increase in future. Price of vehicle will reduce due to increase in production rate of hybrid
electric vehicles.
