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 介绍新能源汽车的短篇作文

今天，我来到萧山休博园参观新能源汽车。其实我来这里有两个目的。第1，就是来参观汽车。第2就是选一个好车尽量低碳减排。这样才能既环保，又能方便我们的生活。
我之所以不让我爸买汽车，是因为现在大多数汽车都是以油驱动，很不环保。所以我经常叫他们购买环保汽车。
我对新能源汽车总是情有独钟，一进场就直奔环保汽车区。在那里我看到了许多新鲜的车，简直是闻所未闻。有柴电混合的，有纯电的，还有太阳发动的。简直是数不胜数，平日里见过的和没见过的都在这里看到了。那些转瞬即逝的酷车在这里都能亲手摸到，甚至可以坐上去体验体验，真是爽！
而且，我还看中了一辆好车。车门是向上翻的，酷毙了！不过，只有两个座位不适合我们家。不过仍然很酷。还有一个是用油的，不过很省油，是新赛欧。全都很好看！
参观完这次车展我感到了科技的进步。

Ⅲ 用英语写一篇关于电动汽车的优点以及建议的短文

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:电动汽车的好处(说明文)300字

《电动车自述》 我是一辆电动车，被主人称为自行车改良型女士车。 作为电动车中幸运儿的我，非常荣幸地被主人挑选到，我的同伴们也嫉妒我。因为我当选的条件统统具备在身，就等显出高招。 我性格开朗、温和。爱穿红白搭配的衬衫，红是品红，白是丝毫无污染的雪白，穿上它，就显得我美观大方。 我们家族也有优点和缺点，优点是为“车”善良。不骄傲、狂猛。主人踏在我的脚上时，我会给予主人舒适的“空间”驾驶。缺点是在主人驾驶我的时候看“呜呜”地大吵大闹。对主人可能有些影响。 我默默无闻地为主人跑路，对主人忠心耿耿，跑起来像一匹骏马，所以主人对我爱不释手。 我的后备箱能为主人更方便地携带物品。 我的主人对我很好，非常关心我。我生病了，主人把我领进“医院”看病，还经常到“美容院”给我美容。 我的存在也许会使主人的生活增添强劲的活力。

Ⅳ 谈谈你对新能源汽车发展的看法

新能源汽车，最大痛点就是电池了，虽然有几种比较先进的技术，如特斯拉的电力管理技术、国内的快速充电和换电，但最根本的设施需要巨大投入，当然也包括各大厂家的技术更新和发展。

(5)关于电动汽车发展及建议的作文扩展阅读

新能源汽车优缺点：

优点：技术相对简单成熟，只要有电力供应的地方都能够充电。

缺点：蓄电池单位重量储存的能量太少，还因电动车的电池较贵，又没形成经济规模，故购买价格较贵；至于使用成本，有些试用结果比汽车贵，有些结果仅为汽车的1/7~1/3，这主要取决于电池的寿命及当地的油、电价格。

Ⅵ 关于对电动汽车看法的150字英语作文

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.
目前人们所说的电动汽车多是指纯电动汽车，即是一种采用单一蓄电池作为储能动力源的汽车。它利用蓄电池作为储能动力源，通过电池向电机提供电能，驱动电动机运转，从而推动汽车前进。从外形上看，电动汽车与日常见到的汽车并没有什么区别，区别主要在于动力源及其驱动系统。即纯电动汽车的电动机相当于传统汽车的发动机，蓄电池相当于原来的油箱。 电动汽车由底盘、车身、蓄电池组、电动机、控制器和辅助设施蓄电池六部分组成。由于电动机具有良好的牵引特性，因此蓄电池汽车的传动系统不需要离合器和变速器。车速控制由控制器通过调速系统改变电动机的转速即可实现由于对环境影响相对传统汽车较小，其前景被广泛看好，但
当前技术尚不成熟。
