2. INTRODUCTION
Pedal operated power generation system is a device that uses human
energy to produce electricity for charging a battery.
 It can be used in the villages as useful electricity source for a small family due to
the low initial cost and very low maintenance cost, wide scale application of
‘Paddle operated power generation system’ can be a suitable source of renewable
energy.
 Application of Pedal Powered Generator :-
 Pedal powered generator can be used to charge the battery which may be a great
opportunity of people of remote area to use telecommunication system.
 It can be a great source of light during night time and save a great amount of
electricity.

3. Selection of Components
 2.4.1 Selection of Battery
. Battery selection depends on load. Capacity of the battery must
be increased for the higher power consumption. A sample
calculation for selection of battery is provided below:
Battery rating: (12V , 2.5 Ahr)
(2 Batteries)
Max Power Stored in Battery =12*2.5*2= 60.0 Watts
Storage energy capacity of Battery = Power* Time (Time=1 hr)
 = 60 watts hr

4. Selection of Alternator
 It is an AC component and provides DC current due to
rectifier circuits. The major advantages of automotive
alternators are,
- Easily available
-Compact in size
 -Repairing cost is low
output depends both on the rotor speed and the Field
currentPermanent magnet generator (DC generator) can
eliminate this problem easily because its terminal voltage
depends on the variation of the speed

5. Rating:
(12-24 V , 1 Ahr)
O/P Power in 1 hr = 24 VA= 24 watts
O/P Energy in 1 hr = 24*1=24 watts hr
 O/P Energy in full rating in 2.5 hrs (150 min)=24+24+12=60
watts hr
 O/P Energy in half rating in 5 hrs (300 min)=
12+12+12+12+12=60 watt hr

6. Pedaling is the operating force of the bicycle. So bicycle frame is the
best option for the pedal power generator setup. General bicycle is
enough for this purpose .
Racing cycle has multigeared power transmission system which
provides the opportunity to increase the speed in very less time by
increasing the gear ratio.
Working principle
First, human energy is transformed into mechanical energy by means
of pedaling. This Mechanical energy is represented in the form of
rotation of chain sprocket system.

7. Second, the mechanical energy in the form of rotation is converted to
electrical energy by the alternator which is connected to the chain-
sprocket and belt-pulley system transmission system by means of
pulley.
At the third stage the electrical energy is converted to chemical
energy in the battery for future use
