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).

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.

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.

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

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

Charger
 It contains a plug that connects electric vehicle
batteries to an electrical source, providing the
batteries with electrical energy.

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

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.

Batteries for the EV
The batteries that are used for electric cars are
rechargeable.

 Flow of electrons can be reversed to “reload” the
negative electrode and makes the battery
rechargeable.

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

13. Mr. SHYAM SUNDAR ROY(Roll# EEE201116075)

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. 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.

Conclusion
With 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.
