Electric Cars Sadie Soliozy

History of the Electric Vehicle Then Now &

History 1830’s - first electric carriage was built the first electric automobile was build in the United States heyday Henry Ford introduces Model T ( top image) Vanguard-Sebring's CitiCar ( bottom image )

History II 1970s - governmental acts GM EV1 ( top image ) a few thousand electric cars were only available for lease GM discontinued the EV1 and “killed the electric car” 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 –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

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

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!
