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]

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.

[5]

Motor Generally the Brushless DC Motor is used. Simpler to maintain, More durable, Smaller. 85%–90% more efficient. Able to self-start.



[6]

Controller Control the BLDC motor. Increase efficiency, reliability and extended battery

life time.



[7]

Charger It contains a plug that connects electric vehicle

batteries to an electrical source, providing the batteries with electrical energy.



[8]

DC/DC Converter Recharges the battery through DC converter. The Iota DLS-55 is the most common option.



[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]

Batteries for the EVThe batteries that are used for electric cars are rechargeable.



[11]

Contd… Flow of electrons can be reversed to “reload” the

negative electrode and makes the battery rechargeable.



[12]

Power from the Electric Motor An electric motor has power and in turn puts out a force that is measured in torque.



[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]

Contd…The electric motor controller takes the power from the batteries and delivers it to the motor.



[15]

Contd… Working of electric engine and BLDC motor.

Various EV



[17]

Advantages

Reduce dependences on oil and gasoline.

Pollutants and noise free. Recyclable batteries. No fire hazards. Low maintenance and operation

cost.



[18]

Disadvantages High price,Tesla modal costs around $50,000. High recharge time. Silence may be fatal. Range lies between 25-30 miles only.



[19]

ConclusionWith this, we come to following facts that number of expected vehicles doubling on the roads in the near future the need for this alternative energy is very evident and has promising returns.Important to produce vehicles that do less, have a longer range, and use less energy. Lower our toxic emissions and localize green house effects.Increase the overall energy efficiency of cars.
