The document outlines a group project on electric vehicles. It discusses the project objectives of researching past and future electric vehicle technology and understanding public knowledge and interest. It divides the tasks among group members and provides an introduction to electric vehicles, including their history and types. It also shares survey results that found most believe electric vehicles can replace gasoline ones, but have limited current knowledge, and are concerned about costs and charging availability. It concludes electric vehicles will become more common by addressing current issues.

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

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.
