This document discusses the challenges and solutions related to electric mobility and power utilities. It notes that 93% of transportation energy comes from fossil fuels that will be depleted by 2050. Electric vehicles can help address this by providing an alternative with no emissions or pollution. However, electric mobility faces challenges related to battery technology, vehicle range, and grid infrastructure. Smart grids and vehicle-grid integration can help optimize electric vehicle charging. Future developments aim to improve batteries and charging solutions to make electric mobility more viable and sustainable.

3. From the Fossil
Fuels…
93% of total transportation energy consumption
is from petroleum.
Research says that the fossil
fuel reserves will be
exhausted completely by
around 2050.

4. From the
Fossil Fuels
(Contd…)
 45% of total CO2
emissions
come from the
fossil fuels
 Future availability
of petroleum poses
economical and environmental risks.

5. AvAilAble
AlternAtives
 Fuel economy improvements in conventional vehicles
 Fuel cell vehicles
 Hybrid vehicles
 Bio fuel vehicles
 Plug-in Electric Vehicles

6. WHY ELECTRIC
MOBILITY?
 Electric vehicles addresses the simultaneous need for
fuel diversity.
 No environmental pollution, green house gas emissions
and thus prevents global warming.
 Electricity is widely available and produced domestically.
 No noise pollution

8. CHaLLEngEs
Finding out the best charging methods for the batteries
 Heavy batteries
 Batteries are very sensitive to over/under charging
 Many electric vehicles have limited range
 For vehicles which are connected to the grid, it can be
cooled or preheated.

9. CHaLLEngEs
(COnTd..)
 Electric mobility also faces several challenges related to the
power grid.
 Electric energy can only be transferred via the distribution
grid.
 It limits the energy flowing in the transmission lines.
 Present distribution transformers across the country do not
have the capability of handling the load demand for EVs too

10. sMaRT gRIds
 Smart grids introduce a two way dialogue where electricity
and information are exchanged between the utilities and its
customers.
 Smart grid enables other technologies to be integrated thus
making the grid autonomous and efficient.
 Major aim of smart grid in India is to optimize the demand

11. Charging
methods
 Charging stations - EVs typically charge from conventional
power outlets or dedicated charging stations.
 Home Refueling
 Battery Swapping
 Replace the entire
chassis of the
vehicle

12. Charging
methods
(Contd..)
 Charging stations that use renewable electricity such as
solar power and wind power are also preferred recently.

13. Comparison
Hybrid Mobility Electric Mobility
Smaller internal
combustion engines
reduce acceleration
No such issues in the
case of acceleration
Requires a lot of
maintenance
Requires only less
maintenance
Less emission Comparatively no
emission at all
Saves a little money More amount of money
is saved as it uses no
fuel
The vehicle drive an
additional range using the
other hybrid fuel
Offer a long electric-
only range than plug-in
hybrids

14. Cost benefit
analysis
 Upon first glance, it seems that electric vehicles have a
higher upfront cost than the conventional vehicles.
 But, electric vehicles can save consumers a huge amount
of money over the vehicle’s lifespan.
 Also, the price of electricity pales while compared to
the refueling costs of a conventional vehicle.
 Maintenance costs are way cheaper in an electric vehicle
than a conventional vehicle.
 That is, the lifespan costs associated with EVs will drop
over time.

& futuRe scopes
 Improved battery management
 Rechargeable lithium-air batteries potentially offer
increased range
 Can employ super capacitors to buffer large but short
power demands.
 Petrol pumps can eventually be converted into charging
stations.

19. conclusion
 The future of transportation vests with the electric
mobility
 The integration of energy and transportation fields will
provide a better and stable electric mobility system
 EV is a great opportunity for the industry to collaborate
for a sustainable future.
 The best thing is that we have only scratched the surface
and there’s more to come in future.
