Advantages and Disadvantages of EVs

The most obvious advantage of electric car batteries is that they don't produce 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 produces pollution. But how does the pollution produced by burning fossil fuels to recharge electric car batteries compare to the pollution produced 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 reduce carbon emissions to less than one percent of those currently produced 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 reduce 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 reduce 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、汽车售后服目前好不成熟,新能源汽车各方面都还在摸索、改善中,对于新能源汽车的售后维修,基本没有很多熟练的维修人员,不能及时维修

3、汽车成本较高,电动车为了能反复充电和续航,必然需要好的电池,好的电机,成本相当高

4、汽车充电难、充电慢,新能源汽车应为受限于各方面的条件,还没有完全普及,充电桩有限。

新能源优点英语作文2

新能源汽车的优点:

1、节约燃油能源。一般是用天然气、石油气、氢气、电力作为动力。2、减少废气排放,有效的保护环境。电动汽车不产生尾气,没有污染。氢能源汽车尾气是水,对环境没有污染。因为基本属于零排放,所以也在限号范围外。3、效率高。一般新能源汽车采用新技术,新结构,使它的效率更高。4、噪声低。新能源汽车缺点:1、因为新能源汽车处于起步阶段,技术还不是很成熟。所以充电比较慢,需要数小时。2、车辆保有量低,充电、加气、维修等不太方便。而且新能源汽车充电难,因为普及面小。3、续航里程短。一般车辆排量较小,动力不足,不适合长距离行驶。4、价格不低。现在价格在5-10万的新能源汽车,只有纯电动汽车有批量生产,选择性不是太大。

扩展资料:新能源汽车是指采用非常规的车用燃料作为动力来源(或使用常规的车用燃料、采用新型车载动力装置),综合车辆的动力控制和驱动方面的先进技术,形成的技术原理先进、具有新技术、新结构的汽车。新能源汽车包括纯电动汽车、增程式电动汽车、混合动力汽车、燃料电池电动汽车、氢发动机汽车、其他新能源汽车等。

新能源汽车两大阶段:第一阶段是以混合动力汽车为主,燃料电池车等新能源汽车为辅的发展方向,开拓新能源汽车市场。第二阶段是在纯电动汽车技术成熟的'基础上,纯电动汽车逐步替代混合动力及燃料电池汽车以至于完全占据新能源汽车市场,实现零排放的阶段。中国新能源汽车产业始于21世纪初。2001年,新能源汽车研究项目被列入国家“十五”期间的“863”重大科技课题,并规划了以汽油车为起点,向氢动力车目标挺进的战略。“十一五”以来,我国提出“节能和新能源汽车”战略,政府高度关注新能源汽车的研发和产业化。

新能源优点英语作文3

新能源汽车的优点一:环保

纯电动汽车在运行过程中可以做到零污染,完全不排放污染大气的有害气体。即使按所耗电量换算为发电厂的排放,造成的污染也少于传统汽车,因为发电厂的能量转换率更高,而且集中排放可以更方便地假装减排治污设备。

新能源汽车的优点 二:省钱

2014年,国家和地方政府给予电动汽车最高11.4万元的补贴,这一举措使电池成本居高不下的电动汽车的售价能够下降到与传统汽车相当的水平。而在油价高企的今天,电动汽车的运行费用是要远小于传统汽车的。

新能源汽车的优点 三:噪音小

电动机在运行中的噪音和振动水平都要远远小于传统内燃机。在怠速和低速情况下,电动汽车的舒适性要远高于传统汽车,随着速度的提升,胎噪和风噪成为噪音的主要来源,两者才回到同一水平上。电动汽车的这一特点对于提升汽车的NVH性能无疑会有很大的帮助。

新能源汽车的优点 四:节能

电动汽车的百公里耗电量为15-20kwh,算上发电厂和电动机的损耗之后,百公里的能耗约为7公斤标准煤。传统汽车按百公里耗油量10L计,能耗约为10公斤标准煤。并且在城市的拥堵环境里,电动汽车的节能优势会进一步放大。

新能源汽车的缺点 一:充电难

在国内充电设施建设滞后的情况下,充电是电动汽车所面临的的一大难题。公共场所充电桩的缺乏严重影响了电动汽车的出行。

新能源汽车的缺点 二:续航里程短

受限于电池的容量,目前大多数的纯电动汽车续航里程都在100-200公里。虽然一再有专家说90%的人每日行驶距离不超过50公里,但是中国消费者对续航的要求比美国人更高,因为很少有中国家庭拥有超过1辆汽车,而美国人可以做到一辆纯电动汽车通勤,一辆传统汽车旅行。纯电动汽车可以满足老百姓平时上下班,但是周末外出,节假日出游的需求,又该如何解决呢?

新能源汽车的缺点 三:充电慢

目前大多数充电桩都是慢充桩,一辆车充满需要5-8小时。虽然可以利用夜间休息时间充电,但是如果遇到什么突发情况,纯电动汽车的充电慢的缺点就会凸显无疑。

新能源汽车的缺点 四:售后服务有待加强

电动汽车结构虽然简单,但是由于动力部分和传统汽车相去甚远,在维修起来还是会遇到一些麻烦。第一个问题就是维修技师的缺乏,现在绝大部分的技师能够修传统汽车,但是缺少电器方面的知识,贸然维修电动汽车不但可能造成车辆的损坏,还有一定的危险性。第二个问题是零部件的稀缺,电动汽车生产量和保有量都少,因此零部件少,价格还高。

以上就是由电动邦我给您分析得关于新能源电动汽车的四大优缺点 。 不知道是否对你们有所帮助,不过时代在更新,相信新能源电动汽车以后的发展肯定会越来越好,并且完善功能。

求帮写英语作文 写未来的智能汽车(smart car)

Many years later, we are driving smart cars on the road. Smart cars are amazing. They can take you sightseeing in the sky or to the sea.

Whenever you go to school and mom and dad can't send you to school, the smart car will drive automatically. As long as you tell its address, the smart car will take you to the place you want to go. Send it to school and tell it to be smaller, smaller , make the smart car as small as a mobile phone, and then put it in the bag, you can go to school.

After the holiday, we can take the smart car to travel, go to the city or go to the countryside.

When you have trouble finding a place to stay, the smart car becomes a place to stay for the night.

When you are at the seaside, the smart car will become a submarine and take you to play in the sea. In the submarine, the window opens slowly. I can touch the sand and stone with my hand, and then I touch the small fish. Then you will find that the water outside the window will not flow in.

Do you want a car like this?

很多年以后,我们的道路上行驶的都是智能汽车。智能汽车很神奇要,它可以带你你天观光,也可以带你入海游玩。

每当上学,爸爸妈妈不能送你去上学的时候,智能汽车会自动驾驶,只要你告诉它地址,智能汽车就会带你到达你想要到的地方。送到学校,告诉它变小、变小……,让智能汽车变得像手机一样小,然后把它放到书包里,就可以上学去了。

当你在海边,智能汽车会变成潜水艇,带你入海玩耍。在潜水艇里,窗户慢慢打开,我伸手一摸,就可发摸到沙石,后来又摸到了小鱼,这时你会发现,窗户外面的水并不会流进来。

这样的车,你也想要一辆吗?

英语作文:无人驾驶汽车的正负面影响

无人驾驶汽车的正负面影响:Driverless vehicles can greatly reduce the occurrence of traffic accidents, thus reducing the probability of traffic congestion caused by accidents. Secondly, smart cars can monitor real-time road conditions through satellite navigation, so as to plan the best route, rather than the phenomenon of vehicles getting together now.

Driverless technology greatly depends on satellite navigation technology. Once the signal is disturbed or even interrupted, driverless is impossible to talk about. Imagine that Google driverless car can't receive the information from Google map on the way, wouldn't it lead to great disaster.

翻译:

无人驾驶汽车可以大幅减少交通事故的发生,从而降低了因为事故而导致的交通拥堵出现的概率。其次,智能汽车可以通过卫星导航监控实时的路况,从而规划出最优的路线,而不是像现如今出现车辆扎堆的现象。

无人驾驶技术极大的依赖于卫星导航技术,一旦信号受到干扰甚至中断,无人驾驶就无从谈起,试想谷歌无人驾驶汽车在行进途中无法接受到来自谷歌地图的讯息,岂不是会酿成大祸。
