    There is now more of said electric car refers to a pure electric car, which is a single energy storage batteries as a power source for vehicles. It uses batteries as energy storage power source to provide power through the battery to the motor, drive motor running to drive the car forward. From the appearance point of view, the electric car and the daily car and did not see any difference, the main difference between the power source and the drive system. That pure electric vehicle motor of a traditional car engine, battery equivalent to the original tank. Electric car from the chassis, body, battery, motor, controller and battery auxiliary facilities of six parts. Since the motor has good traction characteristics, and therefore does not require a battery vehicle driveline clutch and transmission. Speed is controlled by the controller changes the speed of the motor speed control system can be achieved by conventional cars because of the relatively small impact on the environment, the outlook is widely optimistic, but

    The current technology is not yet mature.

    目前人們所說的電動汽車多是指純電動汽車,即是一種采用單一蓄電池作為儲能動力源的汽車。它利用蓄電池作為儲能動力源,通過電池向電機提供電能,驅動電動機運轉,從而推動汽車前進。從外形上看,電動汽車與日常見到的汽車并沒有什么區別,區別主要在于動力源及其驅動系統。即純電動汽車的電動機相當于傳統汽車的發動機,蓄電池相當于原來的油箱。 電動汽車由底盤、車身、蓄電池組、電動機、控制器和輔助設施蓄電池六部分組成。由于電動機具有良好的牽引特性,因此蓄電池汽車的傳動系統不需要離合器和變速器。車速控制由控制器通過調速系統改變電動機的轉速即可實現由于對環境影響相對傳統汽車較小,其前景被廣泛看好,但

    Advantages and Disadvantages of EVs

    The most obvious advantage of electric car batteries is that they don't produce the pollution associated with internal combustion engines. However, they still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere, and right now, most electricity is generated by burning fossil fuels. Of course, this produces pollution. But how does the pollution produced by burning fossil fuels to recharge electric car batteries compare to the pollution produced by internal combustion engines? According to the Electric Vehicle Association of Canada, or EVAC, even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation, such as hydropower and nuclear plants, can reduce carbon emissions to less than one percent of those currently produced by internal combustion engines. So, even in the worst case scenario, cars operated by EV batteries are cleaner than gas-powered cars.

    Another important advantage of battery-powered motors over gas-powered engines is the lower cost of the fuel -- that is, electricity for EVs and gas for the internal combustion engines. The United States Department of Energy has calculated that a typical EV can run for 43 miles on a dollar's worth of electricity. Only a substantial drop in the cost of gasoline could give gas-powered cars anywhere near such a low cost per mile.

    Yet another advantage of these rechargeable batteries is that they recycle well. Almost 100 percent of these batteries can be recycled, which keeps old batteries from becoming a disposal problem.

    The major disadvantage of battery-powered cars, as we mentioned in the last section, is the time required to recharge the batteries. With lithium-ion battery technology, a fully charged EV can travel a distance comparable to an internal combustion engine vehicle with a full tank of gas, but it still needs to be placed on a recharger at the end of that time. At present, this means a drained EV will be out of service for several hours before it's fully recharged. Of course, this is a serious disadvantage. In the future, faster recharging technology may become available, but in the near term, electric cars won't be the vehicles of choice for long trips. Even so, most driving is done relatively close to home and for this reason, battery power will serve as well as gasoline power. A possible solution to the recharging situation may be battery-replacement stations, where instead of recharging your EV you can simply swap your drained battery for a fully charged one. This system would allow batteries to be recharged outside of vehicles and would greatly reduce the amount of time required to get an EV up and running again after its battery is fully discharged.

    Another disadvantage of electric car batteries is their weight. Because they need to do more than traditional car batteries, electric car batteries need to be linked together into arrays, or battery packs, to provide additional power. These collections of batteries are heavy. The lithium-ion battery pack in a Tesla Roadster weighs about 1,000 pounds (453.6 kg). That's a lot of weight to carry and it can greatly reduce the car's range. However, the designers of the Roadster have offset this battery weight with a light frame and body panels. The entire car only weighs 2,690 pounds (1220.2 kg) -- not terribly heavy when you consider that more than a third of that weight is battery.

    Given the importance of the battery to an electric car, you might wonder what will happen as that battery grows older. How long will it be able to power the car? And when it finally dies, can it be replaced or is it simply more economical to buy a new car? Read on to find out.


    1.電動汽車(Developing Electric cars)的開發受到政府重視2.分析原因3.



    The government should increase policy incentives to consumers and accelerate the cultivation of electric vehicle market. The United States has implemented tax incentives for PHEV, with tax cuts between $2500 and $15000.


    Japan has implemented a new "green tax system" since April 1, 2009. It has given tax incentives to vehicles with low emission and low fuel consumption, including pure electric vehicles and hybrid electric vehicles. The annual tax reduction scale is about 210 billion yen, which is 10 times of the current preferential tax reduction.


    From April 1, 2009, the United Kingdom implemented a new automobile consumption tax, which exempted pure electric vehicles from consumption tax. France offers a reward of up to 5000 euros to consumers who buy low emission cars and a maximum of 2600 euros for high emission vehicles.


    On the other hand, the government encourages vehicle enterprises to accelerate the industrialization of electric vehicles by increasing credit support and other measures. The U.S. government subsidizes the production of electric vehicles with loans.


    On June 23, 2009, Ford, Nissan North America Inc. and Tesla automobile company received $8 billion in loans, mainly for the production of hybrid and pure electric vehicles.


    For a long time, the global automobile industry has been actively exploring and striving to promote the transformation of transportation energy and power system in order to solve the constraints of energy and environment and realize sustainable development.


    Especially since 2008, in the face of financial crisis, high international oil price shocks and increasingly severe pressure of energy conservation and emission reduction, the world automobile industry has entered a period of comprehensive transportation energy transformation.


    The development of electric vehicles has become a highly agreed technical route to realize the transformation of transportation energy. The world electric vehicle industry has entered a new stage of accelerated development.



    this paper firstly provides the connotation of new energy automobile,and then gives us an introduction of the development of the new energy automobile,and on the foregoing basis summarizes those factors that will restrict the development of the new energy automobile,and in the end proposes relevant measures for the development therein.
