3. INTRODUCTION
ELECTRIC CAR
 An electric car is an automobile that is
propelled by one electric motor or more,
using electrical energy stored in the
batteries or another storage device.
Electric motors give electric cars instant
torque, creating strong and smooth
acceleration.
 The German Flocken Elektrowagen, built
in 1888, was the world’s first electric car.
Electric cars were also popular in the late
19th century and early 20th century.

4. The first road vehicle achieving a speed of
more than 100 km/h
The French electric vehicle
La jamais contente with 105 km/h in 1899

6. Electric vehicles come in a
broad variety
Plug-in hybrid
passenger car
Small electric vehicles
Plug-in hybrid LDV
Battery LDVs
Elektroroller
Sports cars
Off-road duty vehicle

8. Benefits of electric cars over internal
combustion engines automobiles include a
significant reduction of local air pollution, as
they do not emit tailpipe pollutants, in many
cases, a large reduction in total greenhouse
gas and other emissions.
Less dependency on foreign oil, which in
several countries is cause for concern for
vulnerability to oil price volatility and supply
disruption.
Electric vehicles show significant reductions
in overall well-wheel global carbon
emissions due to highly carbon intensive
production in mining, pumping, refining and
the efficiencies obtained with gasoline.
BENEFITs

9. Historical development of electric cars
Early Years of Electric Cars: 1890 - 1930
 First electric vehicle invented in 1828
 Many innovations followed
 The interest in electric cars increased greatly in the
late 1890s and early 1900s
 First real and practical electric car (with capacity for
passengers) designed by William Morrison
 1902 Phaeton built by the Woods Motor Vehicle
Company of Chicago

10. Historical development of electric
cars
Decline of Electric Cars: 1930 – 1990
 The electric car declined in popularity
because of the following reasons:
◦ Better system of roads  need for longer-
range vehicles
◦ Reduction in price of gasoline  gasoline was
affordable to the average consumer
◦ Invention of the electric starter disposed of the
need for the hand crank.
◦ Initiation of mass production of internal
combustion engine vehicles by Henry Ford.

11. Historical development of electric
cars
 The mid-1930s until the 1960s: dead years for
electric vehicle development and for their
application as personal transportation
 In the 1960s and 1970s: imperative necessity for
alternative-fueled vehicles  renewed interest
on electric vehicles
 The first electric truck, the Battronic Truck,
constructed in the early 1960s.
 The companies Sebring-Vanguard and Elcar
Corporation = leaders in the electric car
production

12. Historical development of electric
cars
The Revival: 1990s
 Efforts by the governments to more stringent air
emissions requirements and regulations requiring
reductions in gasoline use and Zero Emission
Vehicle requirements from several states  revival
 Electric conversions of familiar gasoline powered
vehicles as well as electric vehicles designed from
the ground up became available
(reached highway speeds with ranges of 50 to 150 miles
between recharging)
 Since 2001: Phoenix designs fully functional electric
trucks and Sport Utility Vehicle for commercial fleet
use

14. A few manufacturers are already producing electric
vehicles
Electric vehicles produced in
2010
 Numbers are really tiny compared to world vehicle production of 78 million
units in 2010

15. Economic aspects of e-cars
car The electric propulsion:
efficiency = about 90%
 Electric propulsion is
principally as "clean" as
the energy source
 A photovoltaics-carport
(solar service station)
considered as a
charging station of
electric cars for the
future

16. How does an electric vehicle
work?
 Battery electric vehicle:
Small number of main
components:
• Electric motor
• Large battery
• AC/DC converter
• Electronics...
 No oil or fuel tank
 No exhaust system (tail pipe etc.)
 Hybrid electric vehicle:
• Small combustion engine
• Small fuel tank
• Electronics
 Fuel cell electric vehicle has an additional tank and fuel
cell
 Electric vehicle ≈ several wheels and a plug

17. Electric Vehicles
 Electricity is unique among the alternative
fuels in that mechanical power is derived
directly from it, whereas the other alternative
fuels release stored chemical energy
through combustion to provide mechanical
power.
 Batteries commonly provide electricity used
to power vehicles, but fuel cells are also
being explored. Batteries are energy storage
devices, but unlike batteries, fuel cells
convert chemical energy to electricity.
 The maintenance costs for EVs is less-EVs
have fewer moving parts to service and 17

18. MECHANISM IMPLEMENTED
Controller
BLDC HUB Motor
Steering
Braking

19. CONTROLLER
 The electric vehicle controller is the
electronic package that operates
between the batteries and the motors
to control the vehicle’s speed and
acceleration.
 The controller transform dc from the
battery current into ac and regulates
the energy flow from the battery.
 The controller will also reverse the
motor rotation and convert the motor
into a generator

20. BLDC Hub MOTOr
 Brushless DC motor are more
synchronous motors that are powered by
a DC electric source via power supply
which produces an AC electric signal to
drive the motor.
 It produces higher efficiency and a lower
susceptibility to mechanical wear.
 It has several advantages including more
torque per weight, more torque per watt,
reduced noise, increased reliability and
longer lifetime.

21. STEERING
 Steering is the term applied to the
collection of components,
linkages etc. which will allow a car
to follow the desired course.
steering mechanism: 1 Steering wheel; 2
Steering column; 3 Rack and pinion; 4 Tie
rod; 5 Kingpin

22. BRAKING
Four drum brakes(two rear and two
front) are the brakes planned to
assemble in the electric car.
 Rear brakes are to be engaged
using foot brake system

23. BRAKING
A drum brake is a brake that uses
friction caused by a set of shoes
or pads that press against a
rotating drum-shaped part.

35.  Take 1 Million electric vehicles,
• giving on average 10 kWh = 10 GWh
= 10 minutes of the average German
electricity need
• Loading with 3,7 kW each = 3,7 GW
= 2.4% of installed German power
(155 GW in 2009)
 Electricity need of 1 million vehicles:
• Driving 14 300 km per year (German average) and using 16
kWh/100 km
= 3 TWh/a = 0.5% of annual German electricity use
 Large fleet of electric vehicles offers some power but
small capacity
Myth: “Electric vehicles can help integrating
renewable energies, but they need so much
electricity.”

36. Conclusion & Outlook
 Huge potential for the further emerging of electric
cars
 Although there are still problems, it is important to
push this technology  R&D
 Electrical outlet and electric cable are not required
in future anymore, because the electric car of the
future "refuels" its power fully automatically and
without contacting by induction while driving or
parking.
Figure: Power from the street. The electric car of the future
"refuels" its power fully automatically and without contacting by
induction while driving or parking.
