Vehicles
By Prince Kumar

2. Are Electric
Vehicles
unsuccessful???

3. No, only Electric Cars
haven’t been that much
successful.

4. Present Time Electric Vehicles
● Electric cars come as first example of
Electric Vehicles in our mind.
● E-Rickshaws have been quite a
success in India and are used in many
cities.
● Electric Engines have been proven as
more efficient and economical than
diesel ones.
● The Space Vehicles (satellites, rovers,
spacecrafts) also use electricity.

5. Advantages and
Disadvantages of
Electric Vehicles

6. Advantages:
∎ Lesser Air and Noise Pollution
∎ Provide higher torque and don’t need
multiple gears.
∎ Mechanically very simple and often
achieve 90% energy efficiency over the full
range of speeds and power output.
∎ Lesser maintenance and running costs.
Disadvantages:
● Electricity used by EVs are generated
through non-renewable sources.
● Charging time for EVs is much more
than refuelling time.
● Cost and carbon emission to
manufacture EVs are more than
traditional vehicles.
● Separate infrastructure is required.
● Risk of fire if Lithium ion batteries of
Electric Cars are overcharged.

7. Electric Vehicles vs Gasoline Vehicles

9. Future:
∎ Cars like Nissan Leaf and Tesla Model S have proved that Electric Cars too can be
successful.
∎ The EVs have been proved to be useful in Public Transportation Systems and Space
Vehicles.
∎ Increasing fossil fuel prices specify a need for EVs.
∎ Improvements in technology will improve various concerns related to EVs.
∎ Several countries are promoting Electric Cars by establishing various grants and tax credits
for purchase of new electric cars.
