電動汽車的優缺點英語

1. 新能源汽車的優缺點

凡事都有兩面性，何況是面世不久的新能源汽車。

在目前這個階段，新能源汽車存在的不足方面，我覺得主要是技術的不成熟帶來的。新能源車存在的問題有續航公里數不夠長，導致外出跑長途很不方便；另外充電需要花費較長的時間，也是考驗車主的耐心；還有目前新能源汽車較多的是在小型轎車方面，大噸位的貨車等還較少，應用不夠廣泛。當然這些都是需要一定過程的，傳統汽車能有今天的成績，也不是一早一夕就達到的，因此給以時日，相信這些問題都會解決。

更不用說新能源汽車相比傳統汽車還有那麼多的優點，最明顯的是使用的能源是可再生的，對環境也更友善，不會排放廢氣污染大氣環境；在一些一線城市，還不用排隊搖車牌號，對於很多急需用車的人來說方便很多；在市區使用的話，汽車還很輕便，容易駕駛，電費比油費便宜，還能節約家庭支持。

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.

4. 急需《電動車的利與弊》英語作文

Electric bicycles are at least three advantages: First, to ease traffic pressure. Small footprint of electric bicycles, portable smart, does not need to take a wide path of travel does not need much of parking spaces, which ease the traffic tension in Shenzhen and a serious shortage of parking spaces is very good. The second is concive to environmental protection. Air pollution is largely caused by automobile exhaust, no emissions electric bicycles, less environmental pollution, should be far away from people who work to promote the use of electric bicycles. The third is to ease energy pressures. Now gasoline prices higher and higher, if more use of electric bikes, promote car ownership and use of lower pressure will rece energy demand.
However, the potential traffic safety problems. In response, many readers believe that if the strengthening of management, the introction of restrictive measures, the negative impact can be reced to a minimum. One user pointed out, the ban on electric bicycles is completely unnecessary, because the government can pass legislation on the purchase of electric bicycles, management, road and so set the rules, if the owner does not abide by the rules, traffic police departments strictly enforce the law, to enter the motor vehicle lanes, red light shall be subject to heavy penalties and other acts, as a deterrent, traffic accidents caused by electric bicycle will naturally decrease.

5. 電動汽車有哪些優缺點

優點：
一、電動汽車的優點首先是節約能源，因為電動汽車的主要能源是電力，也就是說根本不會用到汽油，這樣的情況下電動汽車的污染排放量幾乎是零，對於保護環境來說是一個很好的選擇，屬於環保出行工具。
二、中國政府目前對於電動汽車政策方面有一些扶持，雖然力度已經減小，但是起碼在一線城市的話，你會得到一些好處。首先你上牌的話會比較容易，其次稅費方面有一定的優惠政策！這對拿不到車牌的老百姓比較有吸引力。
三、電動汽車駕駛起來比較方便，目前電動汽車就是一個檔位，也就是說幾乎不需要怎麼樣操作。前進的速度方面主要看你踩加速的力度而定，因此駕駛起來比較方便，也比較容易上手。
缺點：
一、電動汽車的缺點也比較多，首先電動汽車市場方面使用的人比較少，因此電動汽車維修的費用高昂，一旦出現任何的問題，那麼必須去4S店面進行保養，這樣一次下來價格至少在一千元左右。
二、電動汽車的市場佔有率很低，因此保值增值率更加低，一般新買的電動汽車，只要一到消費者手裡，直接貶值百分之六十以上，這樣下來買車的消費者損失慘重，只能自己使用，賣掉的話可以說極不劃算！
三、我們知道電動汽車只有一個檔位，因此駕駛起來幾乎沒有任何的駕駛感，同時電動汽車的方向盤指向模糊，因此駕駛起來只有一種方向性，而沒有汽車精確的指向性，因此電動汽車被譽為老年代步車。
四、電動騎車冬季駕駛的話，電池的消耗很大，一般來說一輛官方宣布續航里程三百公里的汽車，冬季的時候至少會消耗三分之一的里程，因此也就能跑二百多公里，因此買電動汽車可以說駕駛的問題很大。
五、電動汽車的電池消耗問題也值得人們考慮，一般來說一組電池價格至少為三千元左右，這樣換算一下，你的電動汽車更換電池至少六七萬元！這個價格幾乎可以買一輛汽油車了，因此購買的時候一定考慮這方面的成本。
六、電動汽車充電的過程很麻煩，一般至少需要兩個小時，可是這屬於快充。對汽車的電池損耗很大。可是適應慢充的話，一般是八個小時以上。這樣的話有任何緊急的事情，根本沒有辦法處理。

6. 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。

7. 純電動汽車優缺點

純電動汽車
純電動汽車(Blade Electric Vehicles，BEV)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，通過電池向電動機提供電能，驅動電動機運轉，從而推動汽車行駛。

優點：

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。望採納，謝謝！
