3. INTRODUCTION
Electric Vehicle – Mission Statement:
In an effort to save the environment and reduce our
dependence on foreign oil, we wanted to convert a
gasoline powered car into an electric vehicle.
4. Kinds of Electric Vehicles
Electric car Golf cart
Nuclear submarine Electric bicycle
6. The Importance of Electric
Vehicles:
Gasoline is a scarce, natural resource.
Electricity is cheaper than gasoline. Electricity can come
from renewable resources such as solar and wind power.
Electric cars pollute less than gas-powered cars.
Electric cars are much more reliable and require less
maintenance than gas-powered cars.
By using domestically-generated electricity rather than
relying on foreign oil, our India can become more
independent.
7. The Problems With Gasoline Powered
Vehicles:
Gasoline Is A Scarce Resource:
Heavy Reliance On Imports:
Creates Smog & Ozone in Big Cities:
Creates Greenhouse Gases:
8. Short History of electric
vehicles
Gasoline vehicles cheaper and faster
from 1920 until today
Renewed interest in 1980s after oil
crises
Today‘s batteries allow longer ranges
Invention of first electric vehicle 1834
Thomas Edison with electric car in 1913
9. The first road vehicle achieving a speed
of more than 100 km/h
The French electric vehicle
La jamais contente with 105 km/h in
1899
11. How do Electric Cars work?
Stores its energy in batteries
Accelerator controls number of volts
delivered to motor
Controller takes power from battery
and delivers it to the motor
Batteries: Lead-acid, nickel-cadmium,
zinc-chlorine, nickel metal hydride,
and sodium-sulfur
12. Recharging
Battery charger transfers electricity
provided by electric utility into the vehicle
battery to recharge it
Full charge takes 3-8 hours
Can go about 100 miles before
recharging
Solectria Sunrise can go 238 miles on
one charge
13. Air pollution
Environmental Concerns: Current use of
heat-combustion engine is a major
source of air pollution and may be a
cause of global warming.
17. advantages
More efficient, lower fuel costs, lower
emissions
Simpler transmission, fewer moving parts
Fuel Choice
Oil/energy independence
Charging EVs represents a small amount
of total power demand
Some batteries have been seen to outlast
the vehicle life
18. Fossil fuels are converted at a power plant,
pollution is more easily controlled
Reduction in global warming pollution
Cost
Electricity: 2-6 cents/mile
Gas: ~8 cents/mile
Electricity is widely available
Considered zero-emission
Less maintenance vehicles
Meet all federal safety requirements
19. disadvantages
Batteries need to be charged.
Car can not be used when batteries are
being charging.
Some Car can only go 40 Miles between
charges.
Battery disposal needs to be carefully
managed.
20. Require charging stations
Battery takes 2-3 hours to get an 80%
charge
Limited range in cold weather
Cost of batteries are high
Electric vehicles are more expensive
when compared to gasoline
vehicles
