Abstract

The continued consumption of non-renewable resources to power today’s vehicles is a

dilemma that must be dealt with swiftly. The solution to this problem is to create a method of

increased fuel efficiency by reducing or eliminating the use of these non-renewable resources.

One possibility that is being proposed is the use of a solar powered vehicle to absorb the energy

provided by the sun and convert it into electrical energy [4]. The electrical energy will be stored

in a rechargeable battery which will be used to power the electric motor [1].

The objective of this project is to create a solar powered vehicle that will benefit the

environment and create a new innovation for future technologies. In order to accomplish this, a

solar powered vehicle will be constructed from scratch to compete in the Shell Eco-Marathon

competition and we will work together with six MEM students. This competition will measure

the amount of miles per gallon (mpg) or energy equivalent to power a vehicle. The goal is to

consume the least amount of energy [5]. By competing in this competition, the added knowledge

and experience can be used to carry over into real life situations, where solar powered vehicles

can be designed and implemented into public use.

Problem Description

The general problem is the strong use of non-renewable resources to power vehicles.

With extensive use, the finite supply of oil may be depleted and will leave the world stranded in

finding a new power source. Not only will the oil be depleted, but the constant use will cause

harm to the environment, air, and the atmosphere. These harmful pathogens are caused by the

carbon emissions of vehicles that are burning fossil fuels, which are toxic at ground level. With

the increase use of vehicles, and the replacement of smaller vehicles with larger vehicles, an

alternative energy will need to be implemented to reduce consumption of the fossil fuels.

A solution will have to be proposed to solve the increase use of fossil fuels. Alternative

energy sources will need to be provided to reduce fossil fuel use and dependency. By

implementing alternative energy, like solar power, fossil fuel use will decrease and the

environment will be cleaner [3]. Plans must be implemented early to avoid future complications.

With planning and education of the problem, the solution will be easier solved. For this project, a

solar powered vehicle will be constructed to help understand and determine its feasibility

capabilities.

The solar powered vehicle will have two front wheels and one rear wheel with the ability

to accommodate one individual. It will be fitted with a solar panel on the roof and/or sides that

collects energy from the sun. This energy is then stored in a lithium-ion battery that will be used

as the main power source for the vehicles electrical components [4]. The battery will be

connected to a motor controller which will power the electric motor. Two joule meters provided

by Shell will be used to measure electric energy consumption by a motor and electric energy

produced by solar panel. A single electric motor will be used and it will provide a power to rotate

4

one rear wheel. The electric motor might be geared in order to provide a rotational moment

sufficient to a speed close to 15 miles per hour. The required torque to propel the vehicle is

approximately 22 pound-foot. The on-board battery will also power all electrical components of

the vehicle.

The construction of the solar powered vehicle will be a joint project with the MEM

department. The MEM group consists of two teams will be responsible for all non-electrical

components of the vehicle which includes the chassis, frame, suspension, gearing, etc. The ECE

group will be responsible for all electrical components of the vehicle. A meeting between the two

groups is held on a weekly basis.

The focus of the project is to meet the requirements to compete in the Shell Eco-

Marathon competition and to provide a solar powered vehicle that is able to produce the highest

efficiency or equivalent miles per gallon rating. For the competition to measure the success rate

two joule meters will be connected to the vehicle that will measure electric power consumed by

the motor and electric power produced by the solar array. The two factors will be used for

conversion to the equivalent miles per gallon rating and the team with the highest efficiency

(miles per gallon rating) will win.

The important factor that needs completing is the decision of the type of solar panel,

battery, electric motor, and electrical components needed to build the vehicle. Calculations are

also required to know the energy ratings for each component. Funding is needed to provide

money to purchase the necessary components of the solar powered vehicle. These tasks will need

to be completed in order to have a vehicle that will meet the design and efficiency criteria.

Proposed Work and Deliverables

The primary goal of the project is to create a functioning electrical system that falls

within the guidelines of the competition. In addition, the design must convey a clear concept of

energy efficiency and allow maximum competitiveness.

Energy Source:

Solar power is chosen as the energy source in our design. Based on the nature of the

competition, a solar powered vehicle is more competitive in terms of energy saving and

efficiency. The history of Shell Eco-Marathon also suggests that solar powered vehicles have a

high chance of producing the most fuel efficient vehicles in terms of miles per gallon.

Solar energy is non-polluting and it is also a renewable resource. Solar power may easily

become the most important source of energy in the future. A solar powered vehicle is one of the

more important applications of solar power and the knowledge gained in the designing process is

very valuable. Furthermore, designing a solar powered vehicle actively promotes the use of solar

power with the idea of clean and renewable energy.

Guideline Principals:

1. Meeting the constraints of race regulations. The main constraints of the competition in

electrical perspective include:

- The sound level must not exceed 90dB when measured 4 meters away from the vehicle

(Article 42) (Refer to Reference [5])

-The vehicle must have a functional external lighting system (Article 59) (Refer to

Reference [5])

6

-Maximum voltage on board of any vehicle must not exceed 48 Volts. Only one battery

per vehicle is allowed. (Article 71) (Refer to Reference [5])

-The electric currents must not exceed 50 amperes permanent and 150 amperes

peak.(Article 80) (Refer to Reference [5])

2. The history of solar racing shows that extremely well performing cars have to stop and

perform vehicle maintenance. This ultimately causes competition loss to reliable, but less

efficient cars. In the design, a method will be defined to try and find the most optimal

combination of the two aspects [2].

3. To improve efficiency, the car should be as light as possible and each component should be

pared to its minimum weight [2].

4. The power loss from electrical parts is unavoidable. We will choose the parts with highest

efficiency possible within the budget limits.

5. The solar panels should be wired in series on a panel and should be divided into several zones.

If one zone fails, other zones are still able to produce energy. A rectification circuit will be

considered for use to adjust the electric power produced by solar array to match system voltage

and allow the system to run as efficiently as possible.

Methodology:

For each component, a chart will be constructed, which will be called a decision matrix.

The decision matrix will lay out the variables to compare, such as cost, efficiency, and weight.

Each category will be given a value between 1-10 (with 1 being the worst and 10 being the best).

The component with the highest score will be chosen.

7

Furthermore, more data can be acquired by using the aid of Simulink (and Matlab) to

obtain further readings about how each component will ideally function in the system. This will

provide more values to compare, which will then be added to the decision matrix.

Existing Systems:

A solar powered vehicle that was built by a team of Purdue University might be

considered as one of the most effective vehicles of its class. The vehicle called Pulsar took first

place at the 2010 Shell Eco-Marathon competition and showed the result which is equivalent to

4548 miles per gallon. The vehicles transmission system has only one gear and its top speed is 25

mph. 300 watt solar panels containing photovoltaic cells were used to power the three-wheeled

vehicle. The weight of the vehicle is said to be 170 pounds [2]. Prospect of using photovoltaic

cells along with static transmission will be evaluated for the solar powered vehicle project.

State of the Art:

There are several major components for the vehicle’s electric system.

Battery Type - lithium ion batteries might be considered as the state of art for power storage

devices. The energy-to-weight ratio of lithium-ion battery is one of the best among other types,

there is also no memory effect (changes in charged/discharged amount of electric power) and the

rate of loss charge is very slow when not in use [1]. The popularity and efficiency of lithium-ion

battery will be considered as primary for our project.

Energy Source - Multifunction solar cells made on a compound-semiconductor technology

were used by the University of Michigan students in another major solar car event, the North

American Solar Challenge. It is highly effective, thin-film flexible solar cells which are just

8

being commercialized. Another type of solar array is crystalline silicon modules. This

technology will help in testing the major electrical components with the use of computer

simulation. Simulink, PowerWorld, or Pspice are software that is going to be used to simulate

electric circuitry and verify design functionality.

Deliverables:

1. Design effective electrical system for solar powered vehicle.

2. Obtain and assemble electrical components of the designed system.

3. The power generated by solar panels together with the power provided by the pre-

charged battery should be enough to power the car to run on a 10 mile course at a

minimum average speed of 15 mph. The optimal power generated should keep the battery

charged throughout the competition. The area available for solar panels in our design is

approximately 4.55 square meters.

4. A rechargeable battery will be used to store electrical energy that is converted from solar

energy by solar cells.

5. A direct current electric motor with approximately 22 pound-foot mechanical torque is

highly possible to be used to drive the vehicle.

6. Measure efficiency of the electrical system, its components and vehicle’s kWh per mile

rating at different levels of sun light intensity. Two joule meters will be used to measure

produced (solar array) and consumed (electric motor) energy. Efficiency of the whole

system will be calculated based on these production and consumption of the energy.

Societal, Environmental, or Ethical Impacts:

By designing alternative energy use to power vehicles, the general public will understand

the importance of cleaner fuel. The alternative power source technology does not have to replace

the current technology, but rather implement it in a way that both technologies are incorporated

together. As time passes, technology will be more advanced and the alternative power source

will hopefully overpower the old technology and reduce or even eliminate the use of fossil fuels.

The people will hopefully be more aware of the impact of renewable resource use and help

contribute in the cause to reduce and protect the environment.

The burning of fossil fuels causes pollution to the earth. The air becomes polluted and the

atmosphere is made weaker. Climate changes can be experienced through the use of these non-

renewable resources. To help reduce hazard and provide positive impact to the environment,

alternative power will be used to reduce the gasses being emitted into the atmosphere. The solar

powered vehicle designed will be a good starting point to remove the wastes of the current fossil

fuel burning engines.

The use of solar power to power vehicles will hopefully inspire major manufacturers of

vehicles to establish a plan to reduce the world consumption of oil. Every effort and idea of solar

12

power implemented in the vehicles design to either increase fuel efficiency or eliminate oil

consumption will make a big difference. As time passes, technology will be more advanced and

have a chance to further the development of this technology. By promoting and planning the

proposed alternative energy early, the world environment will be healthier with the reduced use

of oil consumption. [4]

Summary of Shell Eco-Marathon Competition:

The Shell Eco-Marathon competition traces its roots back to 1939. Scientists at a Shell

plant in the United States had a friendly wager to see who could build the most fuel efficient

vehicle. This competition was revived after a hiatus of several decades when Shell held its first

international competition in 1977 in the UK. The Shell Eco-Marathon Europe is the longest

running continuous Shell international competition, being held annually in France since 1985.

Shell also holds competitions in the United States and Asia. The competition in the United States

is currently held in Houston, Texas at Discovery Green Raceway.

The goal of the competition is to build the most energy efficient vehicle. This is

determined by the car that travels the furthest using the least amount of fuel. The competition is

divided into Prototype and Urban Concept vehicle types. Prototype vehicles have three wheels

while Urban Concept vehicles have four wheels. The competition is further broken up into

different classes by fuel type. Fuels such as diesel, petrol, LPG (Liquefied Petroleum Gas),

electric, hydrogen, ethanol, bio fuels, gas to liquids, and solar cell can be used. Cars must run on

a 10 mile course at a minimum average speed of 15 mph. For each car, the fuel at the beginning

and the end is measured out to determine the fuel economy.

The competition awards trophies and prize money for the winning teams in each vehicle

type and fuel category. An overall Grand Prize is awarded for the best fuel economy for the

13

Prototype and Urban Concept cars in the combustion and fuel cell categories. In addition, many

other prizes are awarded. The following categories are awarded specific trophies or prize money:

Safety, Fuel Efficiency, Technical Innovation, Design, Communications and Marketing, Team

Spirit, and Perseverance in the Face of Adversity.
