Zhigunova Y.N, "Engineering the Electrical Vehicle future"

  1. 1. Theme: « Engineering the Electrical Vehicle future » Student: Zhigunova Y.N Managers: Mikerov A. G. Saint Petersburg Electrotechnical University "LETI" TEP Conference presentation 1886
  2. 2. The object <ul><li>Research of engineering electric vehicles </li></ul><ul><li>it is necessary to consider following problems: </li></ul><ul><li>Battery types </li></ul><ul><li>Power density </li></ul><ul><li>Cost </li></ul><ul><li>Environmentally-friendly batteries </li></ul>Zhigunova Y. N., 6597
  3. 3. Electric Vehicle (EV) <ul><li>uses one or more electric motors for propulsion (instead of an internal combustion engine) </li></ul><ul><li>include electric cars, electric trains, electric lorries, electric aeroplanes, electric boats, electric motorcycles and scooters and electric spacecraft </li></ul>Zhigunova Y. N., 6597
  4. 4. History of the electric vehicle <ul><li>Electric motive power started with a small drifter operated by a miniature electric motor, built by Thomas Davenport in 1835. </li></ul><ul><li>In England a patent was granted in 1840 for the use of rails as conductors of electric current. </li></ul><ul><li>On May, 22-23nd, 2010 midget car Daihatsu Mira EV has passed 1003 kilometers and 184 meters on one charge of the accumulator </li></ul>Zhigunova Y. N, 6597
  5. 5. Battery search <ul><li>Batteries are the Achilles' heel of electric vehicles. It remains the sole barrier to success. </li></ul>One of the earliest rechargeable batteries - the nickel-iron battery - was favored by Edison for use in electric cars. Zhigunova Y. N., 6597
  6. 6. Battery types <ul><li>Lead-acid </li></ul><ul><li>Nickel metal hydride </li></ul><ul><li>Lithium ion </li></ul><ul><li>Fuel cell </li></ul>lead-acid car batter y Zhigunova Y. N., 6597
  7. 7. Electric motor <ul><li>The power of a vehicle electric motor, as in other vehicles, is measured in kilowatts (kW). </li></ul><ul><li>100 kW is roughly equivalent to 134 horsepower </li></ul><ul><li>Direct current (DC) electricity is fed into a DC/AC inverter where it is converted to alternating current (AC) electricity </li></ul>Zhigunova Y. N., 6597
  8. 8. Main advantages of electric vehicles <ul><li>have less noise pollution than an internal combustion engine vehicle </li></ul><ul><li>very simple mechanically </li></ul><ul><li>possibility of additional charge from an electric network </li></ul><ul><li>electricity is cheaper than gasoline </li></ul>Zhigunova Y. N., 6597
  9. 9. Disadvantages of electric vehicles <ul><li>often have long recharge times </li></ul><ul><li>recycling of batteries which often contain poisonous components </li></ul><ul><li>limited range </li></ul><ul><li>some energy needed to heat the interior </li></ul><ul><li>charging stations are required </li></ul>Zhigunova Y. N., 6597
  10. 10. Advanced achievements <ul><li>2011 Chevrolet Volt </li></ul>Eliica Battery Electric Car Zhigunova Y. N., 6597
  11. 11. Conclusion <ul><li>EV is perspective direction in engineering </li></ul><ul><li>EV reduces consumption of organic fuel </li></ul><ul><li>EV is environmentally-friendly system </li></ul><ul><li>EV is cheaper than fossil fuel-powered vehicles </li></ul>Zhigunova Y. N., 6597
  12. 12. <ul><li>Thank you for your attention! </li></ul>Zhigunova Y. N, 6597
