6. INTRODUCTION
“Electric cars ” generally refers to
road going automobiles powered by
electricity .
Propelled by one electric motor or
more using batteries .
Electric motors give instant torque,
and smooth acceleration .

7. History of electric vehicle
 The history of the electric vehicle began in the mid19th
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.

8. Need of electric vehicles
Contributes to cleaner air.
To preserve the fossil fuels.
 Less maintenance
 More efficient
 Cost Effective

9. Components /Parts
Main parts are:
1. Battery
2. Controller
3. BLDC motor
4.Differential
5.Tyres/Rim
6.Chassis

10. Leaf Spring

11. BLDC motor
 BLDC motor works on the
principle similar to that of a
conventional DC motor, i.e., the
Lorentz force law which states
that whenever a current carrying
conductor placed in a magnetic
field it experiences a force.

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

13. Differential
The automotive differential is
designed to drive a pair of
wheels while allowing them to
rotate at different speeds.

14. Power from motor
An electric motor has power
and in turn puts out a force
that is measured in torque.

15. Cont..
 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)

16. Cont..
The electric motor controller
takes the power from the
batteries and delivers it to the
motor.

17. Advantages
Reduce dependences on oil and gasoline.
Pollutants and noise free.
Recyclable batteries.
No fire hazards.
Low maintenance and operation cost.

18. Disadvantage
High price
High recharge time.
Range lies between 25-30 miles only.
Time required to recharge the batteries
is more.
The batteries provided are quite heavy
increasing the net weight of the car.

19. Working
 The driver presses the
accelerator which in turn
sends the signals to the
controller .
 When fully accelerated,
maximum voltage is supplied
to the motor .

20. Types Of Electric Vehicle
Hybrid ElectricVehicle
Plug-in Electric Vehicle
All Electric Vehicle

21. Cont…

22. Battery Electric Vehicle
Battery electric vehicles are all electric.
 No internal combustion engine
Needs large recharge time (7-8 hours)
 Car halts when the battery dies.
In order to run 80 plus miles, it requires a
large battery i.e, 18kWH to 36 kWH.

23. Compare with Combustion cars
ELECTRIC CARS COMBUSTION CARS
ENERGY From electricity produced by batteries By combustion of fossil fuels
and petroleum
PRICE Slightly higher due to expensive
batteries
Cheaper than that of electric
vehicles due to cheaper parts
POLLUTION Doesn’t produce harmful emissions
and contributes in clean air.
Produces harmful carbon
emissions therefore polluting
the air.
RUNNING
COST
Running cost is low due to lesser
number of parts.
High due to more number of
parts and replacement of oils,
etc.

24. Cost Effectiveness
ELECTRIC CARS COMBUSTION ENGINE CARS
PRICE Expensive due to expensive
batteries
Cheaper than electric cars.
FUEL RATE Electricity rate may vary
place to place.
Fuel prices remains almost constant
in every region across the world.
SERVICING Most companies don’t have
certified mechanics for
servicing of electric cars.
A lot of mechanics know how to
service a combustion cars

25. Positive outcomes on environment
Electric cars contribute to cleaner air.
Reduced carbon emissions hence less air
pollution.
 Produce 27% less carbon(monoxide and
dioxide) than combustion engines.

26. Conclusion
 EV has reduced carbon emissions significantly
in the area where it is used.
 Increase the overall energy efficiency of cars.
 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.
