ABSTRACT

Our goal for this project is to design and implement hybrid bicywill be beneficial to the planet. Looking at the growing statistics

pollution and fuel consumption we decided to work on this. The hybrid bicycle offers a cleaner alternative to travel short-to-

distances rather than driving a gasoline-powered car.

The DC power generated by dynamo can be stored via batteriesto drive a motor. Whenever there is a uphill, the motor can be tand thus the bicycle will act as electric vehicle.

Hybrid Bicycle is not a new idea, with many created by hobbyisresidential use with small scale energy in mind. We are looking upon these designs and build a modified hybrid bicycle that wilhuman power into electrical power. The objective is to build a dis safer and more power efficient.

When we pedal the bicycle, the rotational motion of the

tyre will be used to convert mechanical energy produced

directly into a DC voltage through a dynamo and regulatcircuit. Initially voltage produced from dynamo is passed

through a full wave bridge rectifier to get pure DC voltag

This DC voltage can then be stored in a lead acid batter

later it can be discharged to drive the motor.

WORKING

The working of the hybrid bicycle can be explained as follo

1) Dynamo :- Dynamo will act as the dc power generator.The dynamo

coils of wire and magnetic fields to convert mechanical rotation into electric current through Faraday's law of induction. A dynamo machi

stationary structure, called the stator, which provides a constant mag

a set of rotating windings called the armature which turn within that f

of the wire within the magnetic field causes the field to push on the e

metal, creating an electric current in the wire. The output(7 V, 700 m

the dynamo is connected to the charging circuit.

2) Regulation circuit :- The regulation circuit takes the varying input frregulates it to give a constant output of (7 V, 700 mA). The circuit co

317(regulator ic), 10 micro farad capacitor, potentiometer (10 K-Ohm

resistor(383 ohm). The output of this circuit is given to the charging c

3) Charging circuit :- The output of regulation circuit is given to the lead

Diodes are connected to avoid the backflow of current. The rating of the

4) Control circuit :- This circuit consists of ARM based microcontroller .

triggering of the motor for hilly region. Whenever a hill is encountered, thwill give signal to the microcontroller which in turn will activate the motor

will drive the bicycle until a flat surface is sensed by the accelerometer.

5)DC Motor :- The DC motor will rotate via the batterys output power an

bicycle will act as electric vehicle.

6)Driver circuit :- Normal DC motors require current greater than 250 m

Microcontroller ICs cannot supply this amount of current. Hence, we us

abridge between them. Driver circuit will incorporate L293D IC.

WHY HYBRID BICYCLE?The power crisis will not be getting better in the future. The U.S. Ener

Administration stated in their International Energy Outlook Report for

world energy consumption will increase by 49 percent, or 1.4 percent

495 quadrillion Btu in 2007 to 739 quadrillion Btu by 2035, as shown any growth in the worlds energy supply and infrastructure is to occur

is likely the majority of this energy will go to these developed countrie

developing or third world country. This will only exasperate the needs

of these developing and third world countries. Oil is by far the most u

product in the worlds energy supply .

According to the International Energy Agency, oil products make up o

worlds energy supply.

The amount of CO2 produced due to burning of fuel is the major sou

in pollution.

This hybrid bicycle is an alternative to use more sustainable and ene
