5. Introduction
 What is Electric Vehicle?
 Mainly 3 Types
 Directly powered from an external power station
 Powered by stored electricity originally from external
power source
 Powered by on-board electrical generator
 History
 There is no certain inventor
 Started in the 19th century
 Became more popular in the early 20th century

7. Content Information: Facts
 Powered by an electric motor rather than a gasoline
engine
 Impossible tell whether it is an electric as mostly
electric cars are created by converting a gasolinepowered car, biggest clue is the fact that it is
nearly silent

8. Content Information: Facts
Japan
US
France
• more than 28,000 electric cars have
been sold through Dec 2012
• Largest fleet of plug-in electric
vehicles in the world
• More than 14,600 electric cars have
been registered through Dec 2012

9. Content Information: Charging
System
 Goals:
 To pump electricity into the batteries as quickly as the
batteries will allow
 To monitor the batteries and avoid damaging them during
the charging process
 Abilities:
 monitor battery voltage, current flow and battery
temperature to minimize charging time
 sends as much current as it can without raising battery
temperature too much

10. Content Information: Pros / Cons
Pros
 Create less pollution than gasoline-powered cars
-> eco- friendly
 Quiet
 Reduce energy dependence
 Energy efficiency

11. Content Information: Pros / Cons
Cons
 Expensive
 Hard to find charging facilities
 High maintenance fee
 Takes more time for charging

19. Analysis of survey result(1)
From the graph, it shows that……………
 most of the respondent think that there is a
positive prospect of electric vehicle -> as
technology become more advanced, electric
vehicle may become more user-friendly
 The younger the respondent, the more they think
that electric vehicles can replace gasoline vehicles
in the future -> experience advanced technology,
are confident with the prospect of electric vehicles

vehicle?
Expert
Know well
Little bit

21. Analysis of survey result(2)
From the graph, it shows that……………
 most of people have limited recognition
about electric vehicle -> shows that the
popularity of electric vehicle is not very high
 the number of people who know very well
about electric vehicle is one of the least

23. Analysis of survey result(3)
From the graph, it shows that……………
 Cost is there first concern when they buy a car
 The number of recharge station is their second
concern
 -> in order for electric vehicles to become more
common, these factors are the problems that need to
be solved
23

24. Future Development
 By the year 2020 30% of the cars driving on
the road will be battery electric or plug-in
hybrid
 One in 10 cars globally will run on battery power
alone by 2020
 By 2020 electric vehicles and other green cars will
take a third of the total of global car sales

26. Conclusion
 This data analysis reflects the current environment
that the electric vehicle faces today.
 It represents what people want from the electric
vehicles in the future.
 The technology development and new inventions
will lead the electric vehicles to be more common in
the public.
