3. INTRODUCTION
Electric scooters are small vehicles that move using electricity. They have
become very popular for short trips in busy cities. People like them because
they are good for the environment, and they are easy to use. A few years ago,
many companies started making electric scooters, and the batteries in them
got better. But, the rules for using them were different in different places.
People started renting scooters for quick rides. Now, in a city called
Tiruchirappalli in India, there is a new idea for electric scooters. They want to
make scooters that can use solar energy for power, which is good for the
environment. If the sun is not shining, they can still use the regular electric
power. They also want to make the scooters safer by adding a smart sensor for
better brakes. This will make the scooters more innovative and safe to use.

4. PARTS
IRON PIPES: Iron pipes in electric scooters make the frame strong and durable. They
are tough, affordable, and easy to customize, ensuring a stable and safe ride.
D.C MOTOR: The DC motor in an electric scooter turns electricity into motion,
making the scooter move.
SOLAR PLATES: Solar plates for scooters use sunlight to make electricity, helping
power the scooter in an eco-friendly way.

5. SOLAR INVERTOR: Solar inverter turns sunlight power into home electricity.
BACKUP BATTERY: Extra power for when your main battery runs out.
SPEED CONTROLLER: Device that manages how fast or slow something moves, like
adjusting the speed of an electric scooter.

6. WHEELS: Circular objects under a vehicle that help it move.
BRAKES: Parts on a vehicle that slow it down or make it stop.
SHOCKS: Parts in a vehicle that absorb bumps and vibrations, providing a smoother
and more comfortable ride.

7. PROBLEM STATEMENT
The electric scooter relies on a battery for power and due to that it is low
efficient vehicle as compare to other commercial vehicles. To enhance the
efficiency it is necessary to design an efficient power source which not only
just increase the power rate but also match with load carrying capacity.
SCOPE OF THE PROJECT
As automation industry is emerging day by day and emission from vehicles are
major factor in global warming. Electric scooter plays vital role here, following
our sustainable development goals (SDG’s). It is completely emission free
vehicle and easy to use. By increasing its efficiency and introducing more
efficient type of power source that is solar used in this project can be another
mile stone in advance automation system.

8. OBJECTIVES
The primary objectives of this study are to enhance the overall efficiency of
the object by focusing on three key aspects: the development of a solar-
powered energy source, advancements in suspension technology, and
resolution of brake-related issues. However, following are the objectives of
this project.
1. To develop the mechanical structure of electric vehicle.
2. To develop a robust power source utilizing solar energy systems.
3. To enhance and refine the suspension system for improving the overall
performance.
4. To implement an andvanced braking system.

9. METHODOLOGY
In this project, our aim is to increase the efficiency of the electric scooter by
means of adding solar power, suspension and braking system. Figure1 illustrate
the proposed methodology of our work. The selection of material is being
carried out first because it is necessary to select proper material for our
fabrication of electric scooter in terms of load. After that, a proper selection will
be carried out for actuator used in electric scooter. Along with it a suspension
system and design of solar plate or cell will be carried out. A proper selection of
sensors for antilocking brake system and speed would be selected. In last testing
of our model and validation would be done.
