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.
② 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。
③ "純電動汽車" 英文術語怎麼寫
如果一般地說「電動汽車」,可以說electric vehicle/car
但如果強調是「純電動汽車」,則可以說 a hundred-percent/100% electrically powered vehicle/car
斜杠/等於「或」
④ 電動汽車的英文是什麼
electric vehicle
⑤ 用英語介紹你有一輛電動車
nly by her embarrassment at not having deciphe
⑥ 純電動汽車和混合動力車概括為什麼英文名稱是
1.純電動汽車:Blade Electric Vehicles。
2.混合動力車:Hybrid Electrical Vehicle。
1.純電動汽車(Blade Electric Vehicles ,簡稱BEV),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。
2.混合動力汽車(Hybrid Electrical Vehicle,簡稱HEV) 是指同時裝備兩種動力來源——熱動力源(由傳統的汽油機或者柴油機產生)與電動力源(電池與電動機)的汽車。通過在混合動力汽車上使用電機,使得動力系統可以按照整車的實際運行工況要求靈活調控,而發動機保持在綜合性能最佳的區域內工作,從而降低油耗與排放。
⑦ 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.
⑧ 新能源電動汽車的介紹
新能源電動汽車,英文:(New energy electric vehicles )新能源電動汽車的組成包括:電力驅動及控制系專統、驅動力傳動等機械繫統、完成屬既定任務的工作裝置等。電力驅動及控制系統是電動汽車的核心,也是區別於內燃機汽車的最大不同點。電力驅動及控制系統由驅動電動機、電源和電動機的調速控制裝置等組成。電動汽車的其他裝置基本與內燃機汽車相同。

Environmental protection everybody has a responsibility
Now, the pollution already has become the globalization question. The air, Haihe river, the soil pollution extremely is all harmful to the humanity and the zoology and botany
For example, because present automobile more and more many, therefore the waste gas discharges also day by day increases, as the matter stands our air is polluted extremely seriously, this is extremely harmful to our health. Also, the water source under ours destruction, the pollution extremely is also serious, again like this gets down our humanity to be able to perish.
For our humanity, therefore we must adopt the effective action antipollution, the purification environment, protects the ecological equilibrium. For example, we may the afforestation prevent soil erosion. We may develop the new energy and so on. Environmental protection everybody has a responsibility.
