Advantages and Disadvantages of EVs
The most obvious advantage of electric car batteries is that they don't proce 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 proces pollution. But how does the pollution proced by burning fossil fuels to recharge electric car batteries compare to the pollution proced 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 rece carbon emissions to less than one percent of those currently proced 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 rece 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 rece 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.

Ⅱ 介紹新能源汽車的短篇作文

今天，我來到蕭山休博園參觀新能源汽車。其實我來這里有兩個目的。第1，就是來參觀汽車。第2就是選一個好車盡量低碳減排。這樣才能既環保，又能方便我們的生活。
我之所以不讓我爸買汽車，是因為現在大多數汽車都是以油驅動，很不環保。所以我經常叫他們購買環保汽車。
我對新能源汽車總是情有獨鍾，一進場就直奔環保汽車區。在那裡我看到了許多新鮮的車，簡直是聞所未聞。有柴電混合的，有純電的，還有太陽發動的。簡直是數不勝數，平日里見過的和沒見過的都在這里看到了。那些轉瞬即逝的酷車在這里都能親手摸到，甚至可以坐上去體驗體驗，真是爽！
而且，我還看中了一輛好車。車門是向上翻的，酷斃了！不過，只有兩個座位不適合我們家。不過仍然很酷。還有一個是用油的，不過很省油，是新賽歐。全都很好看！
參觀完這次車展我感到了科技的進步。

Ⅲ 用英語寫一篇關於電動汽車的優點以及建議的短文

the good thing about electronic automobile car is that it is driven by electricity instead of petroleum. It does not give out bad smoke and does not pollute the environment.
It is smaller in size and the road get less congested.

Ⅳ 作文:電動汽車的好處(說明文)300字

《電動車自述》 我是一輛電動車，被主人稱為自行車改良型女士車。 作為電動車中幸運兒的我，非常榮幸地被主人挑選到，我的同伴們也嫉妒我。因為我當選的條件統統具備在身，就等顯出高招。 我性格開朗、溫和。愛穿紅白搭配的襯衫，紅是品紅，白是絲毫無污染的雪白，穿上它，就顯得我美觀大方。 我們家族也有優點和缺點，優點是為「車」善良。不驕傲、狂猛。主人踏在我的腳上時，我會給予主人舒適的「空間」駕駛。缺點是在主人駕駛我的時候看「嗚嗚」地大吵大鬧。對主人可能有些影響。 我默默無聞地為主人跑路，對主人忠心耿耿，跑起來像一匹駿馬，所以主人對我愛不釋手。 我的後備箱能為主人更方便地攜帶物品。 我的主人對我很好，非常關心我。我生病了，主人把我領進「醫院」看病，還經常到「美容院」給我美容。 我的存在也許會使主人的生活增添強勁的活力。

Ⅳ 談談你對新能源汽車發展的看法

新能源汽車，最大痛點就是電池了，雖然有幾種比較先進的技術，如特斯拉的電力管理技術、國內的快速充電和換電，但最根本的設施需要巨大投入，當然也包括各大廠家的技術更新和發展。

(5)關於電動汽車發展及建議的作文擴展閱讀

新能源汽車優缺點：

優點：技術相對簡單成熟，只要有電力供應的地方都能夠充電。

缺點：蓄電池單位重量儲存的能量太少，還因電動車的電池較貴，又沒形成經濟規模，故購買價格較貴；至於使用成本，有些試用結果比汽車貴，有些結果僅為汽車的1/7~1/3，這主要取決於電池的壽命及當地的油、電價格。

Ⅵ 關於對電動汽車看法的150字英語作文

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，即是一種採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並沒有什麼區別，區別主要在於動力源及其驅動系統。即純電動汽車的電動機相當於傳統汽車的發動機，蓄電池相當於原來的油箱。 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。由於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於對環境影響相對傳統汽車較小，其前景被廣泛看好，但
當前技術尚不成熟。
