Glimpse at evolution of electric cars.


<ul><li> 1. Electric Carevolution<br />David Burns<br />David Mejia<br />Ormond Emmons<br /></li></ul> <p> 2. In the Beginning<br />Between 1832-1839 a Scottish inventor named Robert Anderson invented the first electric carriage.<br />Due to technological restrictions batteries were unable to be re-charged and top speeds were very low (around 4mph)<br /> 3. Progression continues<br />In 1859 a French physicist named Gaston Plant invents a re-chargeable lead-acid battery.In 1881 Camille Faure improves on his design to create the basic lead-acid battery used in automobiles.<br />As battery technology advanced electric automobiles became more and more popular.<br /> 4. Speed play<br />Thanks to the progression of battery technology higher speeds are able to be obtained.<br />In 1889 JamaisContente achieved a speed of 65.79mph in his rocket shaped electric car.<br /> 5. Electric Boom<br />From 1890 to 1910 electric car manufacturers were abundant and considered more reliable than gas powered vehicles.<br />By 1915 the price of electric cars is higher than gas so public interest shifts.<br /> 6. Manufacturer Comparison<br /> 7. Electric Slide<br />Several factors contributed to the decrease in popularity of electric vehicles.<br />The increasing cost of electric vehicles plus the abundance of cheap fossil fuels.In 1912, an electric roadster sold for $1,750, while a gasoline car sold for $650.<br />Also the invention of the electric starter made it easier to use a gas car<br /> 8. Less interest<br />Due to the rising popularity of the gas motor, electric cars were demanded less.<br />Some manufacturers still produced electric cars but with less priority.<br /> 9. Electric Charge<br />Rising gas prices and increased awareness for environmental footprints lead to a renewed interest in electric vehicles.<br />Also several amendments were put in place to decrease pollutants thus creating interest in electric vehicles.<br /> 10. More interest<br />With the rising cost of maintaining vehicles and the environmental laws, more and more manufacturers begin to focus on electric vehicles.<br />Even though electric vehicles are more expensive initially consumers begin to consider the long term costs and demand grows as well<br /> 11. More popularity<br />Many car manufacturers begin producing electric cars.<br />Battery technology has continued to advance offering a higher top speed and greater range.<br />Although still not as popular as gas, electric cars have a strong following with environmentalists.<br /> 12. Electric cars of all shapes<br />Many different electric cars are concieved although they are still more expensive than gas the interest continues to grow.<br />Electric cars are beginning to achieve ranges of 150 to 200 miles and charge times are being greatly reduced.<br /> 13. Cool Electric<br />With so many electric car manufacturers out there, which one suits you is a personal decision.However here are several manufacturers that we found impressive and possibly cool.<br />Remember electric motors produce 100% torque at 0 rpms so many electric cars have a factory speed block.<br /> 14. Alias by Zap<br />This cool looking 3-wheeler can do 0-60 in 7.8 seconds which isnt setting records but not too shabby either.<br />It has a top speed of around 75 mph and a range of around 100 miles (range varies depending on average speed)<br /> 15. Tesla Roadster<br />This model is impressive in several aspects.<br />In can do 0-60 in 2.9 seconds and has a top speed of 125 mph with a range of over 244 miles.<br /> 16. Ultimate Aero EV by Shelby Super Cars<br />The fastest electric car to date with a top speed over 200 mph.Accelerates from 0-60 in 2.5 seconds.<br />With a range of 150 to 200 miles and a complete charge time of 10 minutes.<br /> 17. Here are some formulas<br />Range (in miles)=250 x capacity[kWh] / (mass[lbs]^0.6)<br />Horsepower=(torque*RPM)/5252<br />Operation costs=kWh * (cost per kWh)<br /> 18. Moving on up<br />So in closing we showed how electric cars influenced the automotive industry and that they are not a new idea.<br />We have also showed that electric cars are making a comeback and are once again increasing in popularity.<br />There are a lot of electric car manufacturers today and more to come in the future.<br /> 19. THANK YOU FOR YOUR TIME<br /> 20. Have a nice day<br /></p>
