History of the Electric Vehicle

Then

Now

&

History• 1830’s - first electric

carriage was built• 1891 - the first electric

automobile was build in the United States

• 1900 - heyday• 1908 - Henry Ford

introduces Model T (top image)

• 1974 -Vanguard-Sebring's CitiCar (bottom

image)

History II• 1970s - governmental

acts• 1988 - GM EV1 (top

image)• 1997-2000 - a few

thousand electric cars were only available for lease.

• 2003 GM discontinued the EV1 and “killed the electric car”

• 2007- Tesla Roadster, an all electric vehicle. (bottom image)

Differences

• EVs are virtually silent• Some Electric Vehicles (EVs) look no

different from gasoline-powered vehicles.• Under the hood the are very different

– gasoline engine is replaced by an electric motor

– electric motor gets its power from a controller

– controller gets its power from an array of rechargeable batteries.

How it works

Today’s Industry

• GM’s Chevy Volt

• Saturn Vue

• Ford Escape

• Tesla Roadster

GM’s Chevy

Planned to debut in 2010

GM• Develop and launch the first modern-day

electric vehicle back in 1996. – Timing of the EV1 wasn’t right.– Only 800 people were willing to lease it.– And gas was cheap

• Leases were not renewed in 2003• GM is hoping for a better outcome in 2010

The Volt

• Extended-Range Electric Vehicle– (E-REV)

• Powered by GM's innovative E-Flex Propulsion System. Which runs on:– electricity– E85– gasoline fuels

How the Volt Runs

• Runs on strictly electric power for up to 40 miles

• After 40 miles the range-extending power source seamlessly kicks into gear– putting the lithium ion battery pack

to work

The Volt’s Battery

• Similar to the one created for the EV1

• 1/2 the size • 1/3 the weight• Shaped like a T

– to fit into other models down the line

Engineers are continually working on increasing technology

Tesla Roadster

Tesla Roadster

• Fully electric automobile

• Can drive over 220

miles per charge

• Goes from 0-60 mph in

4 seconds

• Comprised of only 4

main components Goes

from

Tesla’s Main Components

• Battery – Combination of lithium ion battery

technology and the Tesla Company’s own unique battery pack.

• Motor • Transmission• Power Electronics Modules

– Translates drives commands

Mileage Example Car: Technology Mileage: Price:Honda Civic Gasoline Engine 36 miles per gallon Starting at $15,400Toyota Prius Hybrid Engine 46 miles per gallon Starting at $22,000Chevy Volt Electric/ Plug-in

Benefits&

Drawbacks

Benefits

• Reduced dependence on foreign oil– could displace 6.2 million barrels of oil

a day

• Zero emissions• Can cost of less than two cents per

mile driven • Can be recharged using a typical

household outlet

Drawbacks

• The prices of Electric Vehicles are still very high

• Most EVs have slow pick-up• Would drastically increase electric

bills • Move pollution and destruction of

natural resources to new areas.

Buckle Up!

The era of electric cars is

NOW!
