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.

『貳』 純電動汽車優點

(一)純電動汽車有以下優點：①零排放。純電動汽車使用電能，在行駛中無廢氣排出，不污染環境。②電動汽車比汽油機驅動汽車的能源利用率要高。③因使用單一的電能源，省去了發動機、變速器、油箱、冷卻和排氣系統，所以結構較簡單。④雜訊小。⑤可在用電低峰時進行汽車充電，可以平抑電網的峰谷差，使發電設備得到充分利用。(二)純電動汽車有以下缺點：(1)續駛里程較短;(2)採用蓄電池及電機控制器使成本較高;(3)充電時間長;(4)目前沒有授權服務站，維護成本較高;(5)蓄電池壽命短，幾年就得更換。
純電動汽車發展存在的問題(一)技術方面在技術能力方面國內的汽車製造商雖然紛紛表示涉足新能源汽車研發和生產，但由於具有高科技含量並且能夠量產的車型有限，且隨著電動汽車競爭的開始加劇，由於研發經費過低，創新動力不足，直接影響我國擁有自主知識產權的電動汽車技術的能力;
二)電池方面「電源」是新能源汽車發展的「技術瓶頸」，當前有兩大主要的問題：一是電池成本較高，電池的能量密度較低，充電後的續駛里程較短等問題;二是未來電動汽車市場會否出現真正意義上的電池回收、租賃及二次製造產業鏈;三是電池介面不同，就像不同品牌的手機充電口不同一樣，「標准」的不確定，會對電動車發展造成很大影響等等。
(三)能源方面純電動汽車本身投資比燃油汽車貴，其使用電力要建設發電廠，建設輸電配電設施，還要建設充電站，還要建設蓄電池廠等，(四)配套設施方面費者不選擇新能源汽車的重要因素還有配套服務的不健全，配套設施少，配套設施建設的滯後和維護保養不方便，充電站在國內如鳳毛麟角，難尋其蹤。

an economically developed coastal cities, in this beautiful city life in the sky was 20 years. The witness to the scene of the historic moment, but in the harmony of the city, there was a scene not in harmony, the electric prevailed. Electric cars a drilling motor vehicles with non-motor vehicle of the legal gaps in the new proct, the electric vehicle of that time there is indeed the Chinese People' s daily on the move brought some facilities. However, things cannot be just one, because everything has two aspects. We would say electric cars the advantages and disadvantages, and only through the only revealed a number of very serious problem. First, let us say electric cars to the people of the benefits. 1, section to environmental protection, and faster than other than motor vehicles soon, and low cost without a licence, driving easily, both young and old suitable "four points mentioned above is electric bicycle in the minds of most people recognized advantage. Now let us look at electric cars the defects and what other places, electric battery should not be permanent, cell damage, replacement rate is high, but battery recovery in the country is still relatively low, this does not fully comply with section to environmental protection concepts, and speed is indeed a bicycle faster than the motor vehicle slow

『伍』 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。

『陸』 用電動車代替燃氣車的好處,英語作文120字

Nowadays,the electric bicycle is developing fast,many kinds of which can be seen on the road.It is popular with more and more people.Why?
The reasons are simple.First of all,it is cheaper and more convenient than the motorbike or the car.What's more important is that it saves strength and goes fast,so the rider feels less tired.Also,it is easy for anybody to drive,no matter you are old or young.Finally,it is not just energy-saving but environmentally friendly as well.
However,the electric bike also has its disadvantages.On the one hand,the rider may lose the alternative to do sport,which is not beneficial to health.On the other hand,it may also lead to more traffic accidents in that it goes extremely fast and its emergency brakes dont't woke well.
Personally,I am of the opinion that the electric bicycle has more advantages than disadvantages.As the saying goes,every coin has two sides.As long as the rider drivers carefully,the number of accidents it causes can be reced to the minimum.In conclusion,the electric bicycle is a promising means of transportation.

『捌』 純電動汽車的優點

1.環保：純電動汽車在運行過程中可以做到零污染，完全不排放污染大氣的有害氣體。即使按所耗電量換算為發電廠的排放，造成的污染也少於傳統汽車，因為發電廠的能量轉換率更高，而且集中排放可以更方便地假裝減排治污設備。
2.省錢：國家和地方政府給予電動汽車最高11.4萬元的補貼，這一舉措使電池成本居高不下的電動汽車的售價能夠下降到與傳統汽車相當的水平。而在油價高企的今天，電動汽車的運行費用是要遠小於傳統汽車的。
3.噪音小：電動機在運行中的噪音和振動水平都要遠遠小於傳統內燃機。在怠速和低速情況下，電動汽車的舒適性要遠高於傳統汽車，隨著速度的提升，胎噪和風噪成為噪音的主要來源，兩者才回到同一水平上。電動汽車的這一特點對於提升汽車的NVH性能無疑會有很大的幫助。
4.節能：電動汽車的百公里耗電量為15-20kwh，算上發電廠和電動機的損耗之後，百公里的能耗約為7公斤標准煤。傳統汽車按百公里耗油量10L計，能耗約為10公斤標准煤。並且在城市的擁堵環境里，電動汽車的節能優勢會進一步放大。
5.結構簡單，維護方便：比較一下電動汽車和傳統汽車的底盤、動力總成，你會發現，電動汽車的結構是如此的簡單。電動汽車不再需要復雜的傳動機構和占據了大量空間的排氣系統，維護起來方便了很多，同時空間也得到了大幅的擴展。並且，電動汽車還能方便地實現四輪驅動。
6.加速快：電動機在全部轉速范圍內都可以輸出最大扭矩，因此起步加速非常迅猛。而傳統汽車一般要到2000轉才能輸出最大扭矩。希望能幫到你，望採納，謝謝！！！
