The Cons The BIG Picture •It’s almost impossible to tell an electric vehicle apart by only looking at the outside of the car; this is because in most cases the electric vehicle is created by replacing the gasoline engine by an electric motor The Pros How electric vehicles work... Why People are interested in electric vehicles:

They create less pollution than gasoline-powered cars because they are powered by an electric motor and not a gasoline engine. Electric Vehicles Presentation by: Tanya Garcia, Ayanna Smith
& Hannah Mallen

It’s almost impossible to tell an electric vehicle apart by only looking at the outside of the car.

We need to look under the hood to see the differences and how electric cars work.

The biggest difference is that the electric car has an electric motor instead of a gas engine. Within an EV, a lot of the things you expect to see are missing. This list includes The muffler, converter, tailpipe and gas tank.

The electric motor is next to the transmission and is attached by an adapter plate.

A controller is connected to the electric motor, which allows power to flow through to the motor. The controller itself is powered by rechargeable batteries. 5. Steering is simple with EVs. The wheels are turned automatically as a charge is sent to the motor.
6. Drive carefully and follow all state mandated road rules.
7. Park your vehicle when you have reached destination.
8. Lastly, remember to plug in your car at night. The charger is near the motor. If you allow your car to charge at night, you can fully charge your batteries. A fully charged car can travel approximately 140 miles. Global warming is
caused by
the emission of
greenhouse gases. Batteries are expensive Electric Cars are silent- this has been known to cause accidents Batteries are HEAVY Batteries are hooked to battery packs to give additional power, but... They can also weigh up to 1000lbs or 1/3 of the weight of the car

This lowers car maneuverability Short range of miles- most electric vehicles cannot travel more than 140 miles fully charged Long Charging Time With a lithium-ion battery, a fully charged EV can travel nearly the same distance as a car with an internal combustion system on a full tank of gas Must be recharged after driven. An EV can be out of service for at least several hours. Impractical

-EVs cannot accelerate or cruise like a gasoline powered car

-Luxuries like air conditioning and radio use up very limited battery life 72% of the totally emitted greenhouse gases is carbon dioxide (CO2) Using Oil as a fuel
contributes to the
Carbon Dioxide
emissions. Because Electric vehicles do no directly produce any emissions, they can significantly reduce CO2 emissions, which are associated with global warming. Some electricity in certain regions does however come from coal burning, which in itself produces CO2 emissions. As electricity production becomes cleaner, the environmental advantages of electric vehicles will increase. Greenberg, Steven. Celebrating Our Independence. N.d. Cartoon Stock, Bath, England. Web. 27 Feb 2013. <http://www.cartoonstock.com/newscartoons/directory/o/oil.asp>. Energy Security In 2011, the U.S. imported 25% of its petroleum. Two-thirds of it was consumed by transportation. A lot of the imported petroleum comes from politically volatile countries. Due to the turmoil, the United States is vulnerable to price spikes and supply disruption. Unlike petroleum, the vast majority of electricity in the United States is produced domestically. Moving away from petroleum and towards electricity, would allow the U.S. to decrease their reliance on imported petroleum and their dependency on these unstable countries.

Electric motors convert virtually all of their fuel energy into usable power. The internal combustion engine is less than 20% efficient. ENERGY EFFICIENCY Energy Efficiency. 2012.

Charging at night can reduce the fuel cost up to one fourth of the price of using gasoline or diesel. Maintenance costs are also much lower with electric vehicles. They do not need tune ups or oil changes. Go Green & SAVE Money Untitled. 2012.

Infrastructure Availability Electric Vehicles and Plug-in Hybrid Vehicles have the advantage of flexibility in fueling. They can charge overnight at a residence or can charge during the day at a workplace or public charging station. The number of publicly accessible charging stations exceeding 7000 in 2012 and is quickly increasing. There is no fuel odor with electric vehicles, as the vehicles do not operate on a combustion fuel.
Electric Vehicles are quiet. The ride is virtually silent.

A LITTLE BIT OF CHEMISTRY The base of the car holds a battery tray. For the majority of models, this tray holds as many as 50 batteries.

Today, many electric vehicles use lithium iodide batteries , as they hold a better charge, and are commonly used in computers.

The necessary functions of the car, such as A/C, is also wired to the battery You've just bought you're first EV!
What now??? 1. To turn your car on, simply put the key in the ignition and turn. The car key is essentially the “on” button.
2. Go into reverse to exit your parking lot. Forward and reverse actions are controlled by a switch that is placed where the manual transmission used to be.
3. As you press down on the accelerator, this signal is interpreted by the controller, which then tells the motor how fast to go. Turning up the throttle is easily done by the driver.
4. Steer clear and look out of your mirrors. [Remember EVs are silent. Pedestrians can't hear you coming.] Frace-Presse, Agence. Untitled. 2013. New York Times CompanyWeb. 26 Feb 2013.

Another reason why reducing the number carbon dioxide emissions is in our best interests: CO2 reacts with water vapor molecules in the atmosphere to produce carbonic acid (H2CO3). Acid Rain is the product of Carbonic Acid in our atmospheres.
