Abstract: Based on growing demand of electrical energy, environmental concern and exhaustion of fossil
the need of eco-friendly power generation using renewable energy resources got invoked and these are
getting utilized in different sectors. In this paper, implementation of electrical assisted bicycle and its
display unit is designed which indicates basic parameters of electrical assisted bicycle. The energy to the
bicycle is provided by rechargeable battery packs and for charging a solar power is used. This system
reduces the efforts of pedaling to the user. In this system a 24 volt, 250 watt motor kit and A display screen
made with TFT (thin-film transistor) display is used. Solar panel used is 37watt 17.60 volt dc power supply
and for better charging in less time higher rating of solar panel can be used. DC-DC boost converter is
used for step up voltage from solar panel.
Keywords: Electric Bike, DC-DC Converter Solar Photovoltaic Module, DC Geared Motor, Lithium Ion

I. INTRODUCTION
Electrical Assisted bicycle is one of different types of electric vehicles which is based on basic cycle to which motor
and other accessories are fitted. Based on recent studies electric bicycles began to play major role due to less efforts,
and simple option for travel and transport problems in rural areas. The main reason for implementation is to reduce the
efforts of pedaling for long distances. This is the best technical application for future generation. This bicycle is battery
operated which is economical, low maintenance cost and less pollution. Bicycle is also incorporated with solar
photovoltaic panel for charging the battery during day time when not in use. The advantages of e-bicycles are existing
from both atmosphere and in energy saving cases, especially in urban transport.
II. REQUIREMENTS OF E-BICYCLE
The basic requirements of e bicycle are dc motor, rechargeable battery and controller.
2.1 DC Motor
DC Motor is attached with gear as shown in Fig.1. The motor speed is calculated as rotations of the shaft per minute
which is known as RPM. The advantages of gear arrangement are it increases the torque and reduces the speed.

2.2 Rechargeable Battery
Lithium-ion battery is used in this implementation which is rechargeable battery of 24 volts and 7.5AH as shown in
figure. These batteries have high energy density and low self-discharge. These batteries have heating issues and lead to
explosions and fires when it get damaged.

2.3 Controller
The basic function of Controller is to receive inputs from different parameters like speed, acceleration etc and
determines and sends the desired signal to them as shown in figure. It supplies voltage to the external modules like
headlight; horn etc with the help of battery power.
The pulse width modulation gives pulses to the driver base on input from accelerator or throttle. This driver controls the
power switches such as MOSFET to control the output speed of the motor. Voltage protection (VP) is to protect battery
when the voltage is lower than controller set value during this PWM circuit turns off pulses to the output. Current
protection (CP) limits higher current and protects controller, battery and motor.

2.4 Display System
The display system displays the monitored values such as voltage, current, temperature and speed as shown in Fig.5
The priority of displaying values of e-bicycle can be modified as per user convenience.

Fig. 6. Solar panel setup
37W Solar panel is placed on top of the e-bicycle by using two supportive stands mounted on e-bicycle as shown in
Fig.6 Since the solar panel output is unstable a dc-dc converter type boost is used for desired stable voltage output. DC-
DC boost converter module steps up the input voltage ranging from 10V to 32V to output voltage ranging from 12V to
35V at up to 150W output.

IV. CONCLUSION
Electric Vehicles are future trend due to increase in consumption of non-renewable resources. In this paper e-bicycle
setup is carried out and display unit is designed to provide details of basic parameters of e-bicycle. Solar panel is
incorporated with dc-dc boost converter which is useful for battery charging. The motor and battery can be changed or
assembled with other specifications based on the requirement such as load, speed, distance coverage and battery
discharging time.
