Electric cars are automobiles, which are powered by the electric engine and electric energy. The development of the electric vehicles is a very perspective and important process. Scientists and engineers managed to create electric engines which are no less effective than the ordinary engines used today. It is obvious that electric cars are more ecologically safe and require less energy for work. EVs provide fast acceleration by delivering power instantly to the wheels by providing high torque at low speeds; they give a feel of smooth and quick responsiveness (Technology).

  • I’ve personally never heard of companies who can produce a paper for you until word got around among my college groupmates. My professor asked me to write a research paper based on a field I have no idea about. My research skills are also very poor. So, I thought I’d give it a try. I chose a writer who matched my writing style and fulfilled every requirement I proposed. I turned my paper in and I actually got a good grade. I highly recommend ⇒ www.HelpWriting.net ⇐

  1. 1. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [1] Electrical Car/Vehicles SEMINAR ID : 673 By Mr. SHYAM SUNDAR ROY Roll#EEE201116075 Under the guidance of Ms. Gayatri Nayak
  2. 2. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [2] Introduction Electric cars are automobiles, which are powered by the electric engine and electric energy. The development of the electric vehicles is a very perspective and important process.  EVs, are vehicles that are powered by an electric motor instead of an internal combustion engine.
  3. 3. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [3] History of the Electric Vehicle  The history of the electric vehicle began in the mid- 19th century.  1832: Robert Anderson invents a non-rechargeable electric carriage.  1835: Thomas Davenport builds the first practical electric vehicle.  1976: General Electric was chosen to construct a parallel-hybrid sedan, and Toyota built its first hybrid car.
  4. 4. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [4] Components Motor Controller Charger DC/DC Converter Contactors Batteries
  5. 5. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [5] Motor  Generally the Brushless DC Motor is used.  Simpler to maintain, More durable, Smaller.  85%–90% more efficient.  Able to self-start.
  6. 6. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [6] Controller  Control the BLDC motor.  Increase efficiency, reliability and extended battery life time.
  7. 7. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [7] Charger  It contains a plug that connects electric vehicle batteries to an electrical source, providing the batteries with electrical energy.
  8. 8. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [8] DC/DC Converter  Recharges the battery through DC converter.  The Iota DLS-55 is the most common option.
  9. 9. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [9] Contactors  This is like a big ON switch, powering up the drive circuit when we turn the key.  The Nanfeng ZJW400A is an economical option, or the Gigavac GX14 is a higher powered option.
  10. 10. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [10] Batteries for the EV The batteries that are used for electric cars are rechargeable.
  11. 11. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [11] Contd…  Flow of electrons can be reversed to “reload” the negative electrode and makes the battery rechargeable.
  12. 12. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [12] Power from the Electric Motor  An electric motor has power and in turn puts out a force that is measured in torque.
  13. 13. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [13] Contd… The basic equation for power is: P = Tw (1) For a basic motor there are two parameters that can help show how the motor works.  Velocity function: P (w) = - (Ts / wn) w2 + Ts w (2)  Torque function : P (w) = - (wn/ Ts) T2 + wnT (3)
  14. 14. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075) B.TECH. TECHNICAL SEMINAR PRESENTATION-2014 [14] Contd… The electric motor controller takes the power from the batteries and delivers it to the motor.
