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


Fig: Mild 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


Fig: Medium 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.

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


Fig: 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)


Fig: Battery


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


Fig: Controller


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.
