Electric car

  1. 1. In the name of Allah the most beneficent and the most merciful
  2. 2. ELECTRIC CAR BY MURTAZA BILAL 03F-EE-94
  3. 3. CONTENTS <ul><li>Introduction </li></ul><ul><li>History </li></ul><ul><li>Description </li></ul><ul><li>Operation </li></ul><ul><li>Performance </li></ul>
  4. 4. INTRODUCTION <ul><li>An electric car is a car powered by an electric motor rather than a gasoline engine . </li></ul><ul><li>Electric cars create less pollution than gasoline -powered cars, so they are an environment friendly alternative to gasoline-powered vehicles (especially in cities). </li></ul>
  5. 5. HISTORY <ul><li>Thomas Davenport is credited with building the first practical EV In 1834 . </li></ul><ul><li>In 1847 Moses Farmer built a two-passenger electric car </li></ul><ul><li>In 1851 Charles Page invented a 20-mph electric car. </li></ul>
  6. 6. AN EV OF EARLY FIFTIES
  7. 7. BASIC DISCRIPTAON <ul><li>The gasoline engine is replaced by an electric motor . </li></ul><ul><li>The electric motor gets its power from a controller . </li></ul><ul><li>The controller gets its power from an array of rechargeable batteries . </li></ul>
  8. 8. The Motor <ul><li>Electric cars can use AC or DC motors </li></ul><ul><li>If the motor is a DC motor , then it may run on anything from 96 to 192 volts </li></ul><ul><li>If it is an AC motor , then it probably is a three-phase AC motor running at 240 volts AC with a 300 volt battery pack. </li></ul>
  9. 9. The Batteries <ul><li>A battery tray is installed in the floor of the car. </li></ul><ul><li>Fifty 12-volt lead-acid batteries are placed in the battery tray (two sets of 25 to create 300 volts DC). </li></ul><ul><li>The batteries weigh about 1,100 pounds (500 kg). </li></ul><ul><li>The batteries last three to four years </li></ul>
  10. 10. The Controller <ul><li>The controller takes power from the batteries and delivers it to the motor . The accelerator pedal hooks to a pair of potentiometers and these Potentiometers provide the signal that tells the controller how much power it is supposed to deliver. </li></ul>
  11. 11. THE CONTROLLER
  12. 12. The electric motor The controller The batteries
  13. 13. The Charging System <ul><li>Any electric car that uses batteries needs a charging system to recharge the batteries </li></ul><ul><li>To pump electricity into the batteries as quickly as the batteries will allow </li></ul><ul><li>To monitor the batteries and avoid damaging them during the charging process </li></ul><ul><li>It takes about 12 kilowatt-hours of electricity to charge the car after a 50-mile trip. </li></ul>
  14. 14. The 120/240-volt charging system
  15. 15. CAR CHARGER
  16. 16. PERFOMENCE <ul><li>The range of this car is about 50 miles (80 km). </li></ul><ul><li>The 0-to-60 mph time is about 15 seconds. </li></ul><ul><li>It is nearly silent </li></ul><ul><li>When breaks are applied the motor acts as generator and charges the batteries. </li></ul><ul><li>No lubrication required. </li></ul><ul><li>Easy maintenance. </li></ul>
