Transcript

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