Electric Car

In these days, Electric motors are everywhere.In your house, almost every mechanical movement that you see around you is caused by an AC (alternating current) or DC (direct current) electric motor.


A simple motor has six parts:


-Armature or rotor,
-Commutator,
-Brushes,
-Axle,
-Field magnet and DC power supply of some sort


There is an important thing from life which is electric car.

                                                           ELECTRİC CAR

  An electric car is an automobile which is use electric motors, using electrical energy stored in batteries or another energy storage device.

  Electric cars were popular in the late-19th century and early 20th century, until advances in internal combustion engine technology and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicle. The energy crisesof the 1970s and 80s brought a short lived interest in electric cars, but in the mid 2000s took place a renewed interest in the production of electric cars due mainly to concerns about rapidly increasing oil prices and the need to curb greenhouse gas emissions .

  As of March 2012 series production models available in some countries include theTesla Roadster, REVAi, Buddy, Mitsubishi i MiEV, Tazzari Zero, Nissan Leaf, Smart ED, Wheego Whip LiFe, Mia electric, BYD e6, Bolloré Bluecar, Renault Fluence Z.E.,Ford Focus Electric, BMW ActiveE, and Coda. The Leaf, with more than 22,000 units sold worldwide through February 2012, and the i-MiEV, with global cumulative sales of more than 17,000 units through October 2011, are the world's top selling highway-capable electric cars. 

 Electric cars have several potential benefits compared to conventional internal combustion automobiles such as, a significant reduction of urban air pollution, as they do not emit harmful tailpipe pollutants from the onboard source of power at the point of operation;reduced greenhouse gas emissions from the onboard source of power, depending on the fuel and technology used for electricity generation to charge the batteries;and less dependence on foreign oil, which for the United States and other developed or emerging countries is cause for concern about their vulnerability to price shocks and supply disruption. Also for many developing countries, and particularly for the poorest in Africa, high oil prices have an adverse impact on their balance of payments, hindering their economic growth.

                                                                     Future

 The future of battery electric vehicles depends primarily upon the cost and availability of batteries with high specific energy, power density, and long life, as all other aspects such as motors, motor controllers, and chargers are fairly mature and cost-competitive with internal combustion engine components. Diarmuid O'Connell, VP of Business Development at Tesla Motors, estimates that by the year 2020 30% of the cars driving on the road will be battery electric or plug-in hybrid.

Nissan CEO Carlos Ghosn has predicted that one in 10 cars globally will run on battery power alone by 2020.Additionally a recent report claims that by 2020 electric cars and other green cars will take a third of the total of global car sales. It is estimated that there are sufficient lithium reserves to power 4 billion electric cars.
