2. Introduction
• Electric cars are automobiles, which is powered by the electric engine and
and electric energy.
• The development vehicle electric vehicle is a very prospective and
important process.
• Evs are vehicle that are powered by electric motor instead of a internal
combustion engine.

3. History Of The Electric Vehicle
• The history of electric vehicle began in the mid 19th century.
• 1832: Robert Anderson invents a non rechargeable electric age.
• 1835: Thomas Davenport the practical electrical vehicle.
• 1976: General electric was chosen to construct parallel hybrid sedan
and Toyota built its first hybrid car.

4. Components Of Electric Vehicle
• Motor
• Controller
• Charger
• DC/DC Converter
• Contractor
• Batteries

5. Motor
• Generally the brushless DC motor is used.
• Similar to maintain,more durable,smaller.
• 85%/90% more efficient.

6. Controller
• Contril the BLDC motor.
• Increase efficiency reliability and extended battery life time

7. Charger
• It conttain a plug that connect electric vehicles batteries to an
electrical source, providing the batteries with electrical energy.

8. DC/DC Converter
• Recharges the battery through DC Converter.
• The IotaDLS-55 Is the most common option.

9. Contractors
• This is like big ON switch powering up the drive circuit when we turn
the key.
• The Nan feng zjw400A is an economical option or the Gigavac Gx14 is
a higher powered option.

10. Batteries for the EVS
• The battery that is used For electric cars are rechargeable.

11. • Flow of electron can be reversed to reload the negative electrode and
makes the battery rechargeable.

12. Power From The Electric Vehicle
• An electric motor has power tuen puts out aforce that is that is
measured in torque.

13. Contd…
• The basic equations of 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+ Tsw (2)
• Torque function : P(w) = -(Wn/Ts)T2+ WnT (3)

14. Contd…
• The electric motor controller takes the power from batteries and
deliverse it to the motor.

15. Contd…
• Working of electric region and BLDC motor.

16. Various EVs

17. Advantages
• Reduce dependabce on oil and gasoline.
• Pollution and noise free.
• Recyclable batteries.
• No fire hazards.
• Low maintenance and operation cost.

18. Disadvantages
• High price, Tesla modal costs around $ 5,0000.
• High recharge time.
• Range lies between 25 – 30 miles only.

19. Conclusion
• With this we come to folowing facts that number of expected vehicles
doubling on the roads in the near future the need for his alternative
energy is very evident and has promising return.
• Important to produce vehicles that do less have a longer range and
unless energy.
• Lower our toxic emission and localise green house effects.
• Increase the overall energy efficiency of the cars.
