3. History of Electric Vehicles
• It is hard to pinpoint the invention of electric car to one inventor or country, instead it
was a series of breakthroughs from battery to electric motors in 1800’s that led to the first
electric vehicle on the road.
• It was Henry Ford’s mass produced Model T that dealt blow to electric car. By that time the
gasoline car cost was $650 and electric car cost was $1,750.
• In India, the concept of electric vehicles was unveiled under ‘National Electric Mobility
Mission Plan(NEMMP) 2020’in 2013 to address the issues of energy security and vehicle
pollution.
• In 2001, the first ever electric car ‘Reva’was launched in India by Reva Electric Car
Company (now known as Mahindra Electric).
4. Working of Electric Vehicles
The electric
vehicle power
source is a battery
which supplies
theelectric motor
with energy
necessary to
movethevehicle.
The controller
actsasa regulator
and controls the
amountof power
received from the
batteriesso the
motordoes not
burnout.
Since the electric vehicles use an
electric motor the driver can take
advantage of motor’s momentum
when pressure is applied on the
brakes. Instead of converting all the
potential energy in the motor into
heat like a fossil fuel powered car
does, an electric car uses the
forward momentum of the
motor to recharge the battery.
This process is known as
regenerative braking.
5. TYPES OF EVs
Hybrid
Electric
Vehicles
• HEVs are powered by both
petrol and electricity.
HEVs start off using the
electric motor, then the
petrol engine cuts in as
load or speed rises. The
two motors are controlled
by an internal computer
which ensures the best
economy for driving
conditions. HEVs can
recharge the battery
through regenerative
braking . Example: Honda
Civic Hybrid,Audi Q7.
Plug
in
Hybrid
Electric
Vehicles
• These vehicles use
electricity as main source
of energy. The combustion
engine is set-on when the
charging of battery
reaches minimum level.
Recharging the battery can
be done by regenerative
braking as well as plugging
in the charger . Example:
Toyota Prius.
Battery
Electric
Vehicles
• They are only powered by
electricity and do not
have a petrol engine, fuel
tank or exhaust pipe.
They are also known as
plug in EVs. Example:
BMW i3.
6. Comparison
Parameters Electric Vehicles
Conventional Vehicles
Energy From electricity produced by batteries By combustion of Fuel.
Price
Higher due to usage of expensive batteries
and higher maintenance
Cheaper due to more availability and
feasibility of resources
Pollution
Does not produce harmful emissions and
contributes in clean air
Produces harmful carbon emissions
Running Cost Running cost per km is Rs 1.5
Diesel per Km running cost is 4 to 4.5
and petrol per km running cost is 6.5
where as for CNG it is 3 to 3.5
7. Comparison
Parameters Electric Vehicles Conventional Vehicles
No. of Components 30 3000
Maintenance Cost
1. Accident repairs results in
replacement of entire parts such as
body shell, motor and battery
assemblies.
2. The amount of man power
required, yet, is not skilled.
1. The spare parts of the
vehicle are easily available
in the market and results in
replacement of only the
damaged part.
2. The skilled man power is
available.
Infrastructure
The infrastructure in not developed at
a stage where the vehicles can be used
commercially by all.
Developed infrastructure,
where the consumer can avail
the required service at any
place.
8. Lithium Ion Batteries
• Lithium is abundantly available in the world. The battery can be recycled.
• Range
The electric vehicle covers a range of 8 kms per Kwh of Li-ion battery.
The Mahindra e2o uses 11-16 Kwh battery for range of 120 kms.
• Cost
In 2010, the Li-ion batteries cost around $700/Kwh which reduced to $145/Kwh in 2016. It is estimated to
reach $120/Kwh by 2020.
In 2010, for the range of 40 mi(64 kms), the pack of batteries cost $12,000 , whereas, it was $3600. In 2015, It
reached $1500 by 2020.
In India, due to high cost of Li-ion batteries, finance is one of major problems and also warrants a much higher
purchase demand.
• Charging Time
The Mahindra e2o takes around 5 to 8 hrs to charge its 11-16 Kwh battery.
• Efficiency
The batteries can work upto 10+ years and over 7000+ charging cycles.
9. Challenges for Electrification of Vehicles
1. Integration of Electric vehicles within Product Portfolios of OEMs.
2. Collaborations with E-Mobility value chain.
3. Relevant Charging Infrastructure.
4. Marketing of E-Mobility Benefits and Reducing customerAnxiety.
5. Price Customer has to pay to live with an E-Vehicle.
10. Relevant Charging Infrastructure
• Currently there are two types of charging stations, at
home or work. Both of these sources involve legal
challenges in terms of taxations, accounting that needs
to be addressed.
• Public charging infrastructure is still uncertain, as
large scale investment has not yet surfaced to support
public charging infrastructure as stand alone business.
• Charging stations will only start as business by
private firms when there is adequate usage of e-
vehicles in that particular area.
11. FEEDBACK FOR MAHINDRA E20
• Product Specs:
Mahindra E20 is a BEV. It can go up to 100 km. within a full recharge time of 8
to 9 hours. It consists of 3 PhaseAC induction Motor and a lithium ion battery of
capacity 280A. It uses regenerative braking.
• Positive Feedbacks:
1. Great for driving in city.
2. Eco Friendly
3. Less maintenance issues
4. Lower risk of breakdown due to less moving parts.
• Negative Feedbacks:
1. Low Pick up
2. Price is too high
3.Battery life needs to be improves to curb range anxiety
4. After sales service could be an issue
12. USAGE OF EVs BY VARIOUS COUNTRIES
• As of Dec 2016, China has the worlds
largest stock of highways legal light
duty plug in electric vehicles with
cumulative sales of more than
6,45,000 plug in electric cars.
• US ranks second with more than
5,70,000 plug in electric vehicles.
• Japan is the worlds third Largest plug

14. TESLA : A REVOLUTION IN EV
• Tesla was founded by Elon Musk in 2003.
• In March 2008 Tesla began production of Roadster
• In June 2008 it announced Model S
• Tesla launched Model 3 in 2017 which has a high range battery(50 or 75 KwH) which can run for 354 kms
or 500kms repectively.
• In 2017, Tesla filed a patent for a new battery swapping robot that can lift a vehicle and change its battery
pack for a new one in just 15 minutes.
• Tesla has proved the capability of an electric vehicle by developing high performance sports car and
affordable cars for daily commute
15. CONCLUSION
• There are various challenges including financial, technical, supply chain
challenges for development of EVs in India but these challenges can be
solved by a firm resolution by the OEMs and customers.
• Charging stations can be increased once the sales of EVs increase, This
could be achieved by customer awareness about EVs.
• As the use of the EVs increase, OEMs can also bring variety of products in
lower range of prices.
• Educational activities can be organized by OEMs so that the awareness
about EVs is increased, which would further lead to increase in sales.
