电动汽车的优缺点英语

1. 新能源汽车的优缺点

凡事都有两面性，何况是面世不久的新能源汽车。

在目前这个阶段，新能源汽车存在的不足方面，我觉得主要是技术的不成熟带来的。新能源车存在的问题有续航公里数不够长，导致外出跑长途很不方便；另外充电需要花费较长的时间，也是考验车主的耐心；还有目前新能源汽车较多的是在小型轿车方面，大吨位的货车等还较少，应用不够广泛。当然这些都是需要一定过程的，传统汽车能有今天的成绩，也不是一早一夕就达到的，因此给以时日，相信这些问题都会解决。

更不用说新能源汽车相比传统汽车还有那么多的优点，最明显的是使用的能源是可再生的，对环境也更友善，不会排放废气污染大气环境；在一些一线城市，还不用排队摇车牌号，对于很多急需用车的人来说方便很多；在市区使用的话，汽车还很轻便，容易驾驶，电费比油费便宜，还能节约家庭支持。

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《电动车的利与弊》英语作文

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. 电动汽车有哪些优缺点

优点：
一、电动汽车的优点首先是节约能源，因为电动汽车的主要能源是电力，也就是说根本不会用到汽油，这样的情况下电动汽车的污染排放量几乎是零，对于保护环境来说是一个很好的选择，属于环保出行工具。
二、中国政府目前对于电动汽车政策方面有一些扶持，虽然力度已经减小，但是起码在一线城市的话，你会得到一些好处。首先你上牌的话会比较容易，其次税费方面有一定的优惠政策！这对拿不到车牌的老百姓比较有吸引力。
三、电动汽车驾驶起来比较方便，目前电动汽车就是一个档位，也就是说几乎不需要怎么样操作。前进的速度方面主要看你踩加速的力度而定，因此驾驶起来比较方便，也比较容易上手。
缺点：
一、电动汽车的缺点也比较多，首先电动汽车市场方面使用的人比较少，因此电动汽车维修的费用高昂，一旦出现任何的问题，那么必须去4S店面进行保养，这样一次下来价格至少在一千元左右。
二、电动汽车的市场占有率很低，因此保值增值率更加低，一般新买的电动汽车，只要一到消费者手里，直接贬值百分之六十以上，这样下来买车的消费者损失惨重，只能自己使用，卖掉的话可以说极不划算！
三、我们知道电动汽车只有一个档位，因此驾驶起来几乎没有任何的驾驶感，同时电动汽车的方向盘指向模糊，因此驾驶起来只有一种方向性，而没有汽车精确的指向性，因此电动汽车被誉为老年代步车。
四、电动骑车冬季驾驶的话，电池的消耗很大，一般来说一辆官方宣布续航里程三百公里的汽车，冬季的时候至少会消耗三分之一的里程，因此也就能跑二百多公里，因此买电动汽车可以说驾驶的问题很大。
五、电动汽车的电池消耗问题也值得人们考虑，一般来说一组电池价格至少为三千元左右，这样换算一下，你的电动汽车更换电池至少六七万元！这个价格几乎可以买一辆汽油车了，因此购买的时候一定考虑这方面的成本。
六、电动汽车充电的过程很麻烦，一般至少需要两个小时，可是这属于快充。对汽车的电池损耗很大。可是适应慢充的话，一般是八个小时以上。这样的话有任何紧急的事情，根本没有办法处理。

6. 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。

7. 纯电动汽车优缺点

纯电动汽车
纯电动汽车(Blade Electric Vehicles，BEV)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，通过电池向电动机提供电能，驱动电动机运转，从而推动汽车行驶。

优点：

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。望采纳，谢谢！
