The author:(作者)delvpublished in(发表于) 2013/11/8 9:51:51 Next-generation electric vehicles： equipped with wireless rechargeable and lithium-air battery？
Emerging technology consulting firm Enderle, President and principal analyst Rob Enderle said in United States sci-tech news site DigitalTrends published op-ed articles saying that electric cars since the end of the century coming out so far, battery capacity has been a problem for their development problems, and these days, many technologies will help find a solution in the market, were further developed.
Following is the article content:
Earlier in the last century, the first generation of electric vehicles available, but due to battery power, not comparable with the fuel tank, causing derail a large area for electric vehicles. Ten years ago, the carmaker Tesla (Tesla) led the massive second generation electric vehicles, battery earlier had resulted in significant improvements, but still continued to hinder the development of electric vehicles. Meanwhile, fuel economy has been improved significantly, thereby further exacerbating the difficulties of electric vehicles with fuel competition.
Although third-generation electric cars will get numerous improvements, but the most important improvement is the urgent need to address the energy issue. However, the market now has numerous technology eventually could help electric cars will fuel motor vehicle kicked off the playing field.
Inductive charging
Whether Smartphones or the electric vehicles, through Inductive charging technology and equipment without charge through a physical connection to the power supply can be. Funny thing is, although the Tesla electric car launched in 2003, and its leading competitor in every respect, but Nissan and Infiniti are the charging function will first be available companies. You know, auto Inductive charging technology was originally borrowed by Tesla Tesla Roadster that is known to all, but it does not seem to be attracted to Tesla was too keen on.
Qualcomm (Qualcomm) also has its own Inductive charging technology, known as the Halo, can be used for parking and interstate highways. This technique requires cars to maintain a close, but does not need to touch, as opposed to auto insert charging, this technique can be said to be a great improvement. Part of the improvement is, the device can be fully embedded, greatly reduced the damage, or may be "smattering" drivers to the potential for damage. In most cases, you have to do is Park the car, any of the energy consumption of your car for free and you will receive a list of energy consumption at the end of it.
Qualcomm is now promoting this technology unless the technology is on the way, otherwise, it is impossible for solving battery problems, however, can reduce the incidence of related problems, make charges more transparent and reliable. However, the technical standards are inconsistent would create problems, had earlier plagued the entire electric vehicle industry, no uniform standard means, you must find a vehicle you can charge in the parking lot, and road charging solution will not work. This is perhaps why Tesla pace.
Lithium-air batteries
IBM and other companies are developing a promising technology: lithium-air batteries, which can address the energy density of a fuel tank. Over the past few years, metallurgy has made substantial progress, based on technology of lithium-air battery can achieve in 10 years. If the batteries have same energy and fuel tank capacity, and have the same size, and can be used to replace the giant Tesla Tesla s battery, you probably know how to drive this car, then get quadruple miles. When running 1000 miles, you don't have too much to worry about charging plug. More likely is that engineers may use a smaller battery, lighter electric car prices lower. Plus Plug in more widespread, this might become the electric vehicle industry changer, showing that higher energy efficiency than gasoline.
Super capacitor (Supercapacitors and ultracapacitors)
Super capacitor battery replacement, in fact it has been applied to commercial vehicles. Capacitors are solid, it has an almost unlimited life cycle, capable of charging and discharging thousands of times, faster than lithium-ion batteries and will not cause injury. To some extent, capacitors and ordinary batteries are like Flash memory and hard disk, start Flash performance is better, but more expensive than a hard disk. Even iPod first hard drive. But as Flash memory prices to slide, its market share and higher, now the hard disk is being eliminated by the market.
It is unfortunate, early capacitors are still in transition. Now, the capacitor prices are very high, over a period of time charge would have failed, and its lower energy density than batteries. From the capacitor may not solve the electric energy in the near future, but like Flash memory, its price is expected to fall sharply, increased energy density, self-discharge rate will also be improved. However, the capacitor is used in hybrid power plant, users can quickly fully charged capacitor within minutes, then the capacitor will automatically charge the battery on the way users drive.
Where is the next Tesla?
Here I am referring to is not a Tesla in this company, but Tesla this man, he died early, and his death was probably caused by a mysterious death ray, he studied radio energy. Intel and other companies had been trying to break into this area, but running on their personal electronic devices were to be achieved, there is still a long way to go, you want this technology to be able to use on the car, perhaps to wait for decades. However, as soon as the technology developed, it will be able to solve electric car battery problems forever, at that time, we will live in a world of electric, and we will encounter some health issues need to be addressed: glow in the dark it was a cool idea, but we need to avoid the "death ray" part. In any case, I agree that radio energy will promise an era of electric cars forever arrived.

新兴技术咨询公司Enderle总裁兼首席分析师罗布·恩德勒日前在美国科技资讯网站DigitalTrends刊登署名文章称，电动汽车自上世纪末现身至今，电池容量一直是困扰其发展的主要问题，而现如今，市场众多技术将帮助其找出解决方法，得到进一步发展。
以下是文章主要内容：
上世纪早些时候，第一代电动汽车面世，但由于电池能量无法与油箱媲美，致使电动汽车大面积夭折。十年前，由汽车厂商泰斯拉（Tesla）领衔的第二代电动汽车有大规模出现，即便电池较早前有了明显改善，但却仍继续阻碍着电动汽车的发展。与此同时，汽车燃油的经济性也得到了明显改善，从而进一步加剧了电动汽车与燃油类汽车竞争的难度。
虽然第三代电动汽车将得到众多改进，但最重要的改进还是迫切需要解决的能量问题。不过，市场上现在有众多技术，最终能够帮助电动汽车将燃油类汽车踢出比赛场。
感应充电
无论是智能手机还是电动汽车，通过感应充电技术，设备无需通过物理连接至电源便可进行充电。有趣的是，虽然泰斯拉在2003年便推出了电动汽车，而且其在各方面都领先与竞争对手，但尼桑和英菲尼迪却是将首批提供该充电功能的汽车厂商。要知道，汽车感应充电技术最初就是借由泰斯拉的Tesla Roadster为众人所知，但却似乎没有吸引到泰斯拉太大兴趣。
高通（Qualcomm）也拥有自己的感应充电技术，名为Halo，可用于停车场和州际公路。该技术要求汽车保持近距离，但不需要接触，相对于汽车插入充电，这个技术可以说是一个很大的改善。部分改善是，该设备可以完全埋入，大大降低了遭到破坏，或者被“二把刀”司机损坏的可能性。在多数情况下，你要做的就是停好车，你的汽车消费的任何能量都是免费的，而你会在月末收到一张能量消费清单。
高通现正在推广这项技术，除非该技术在路上安装，否则，其无法解决电池续航能力问题，不过，却可以减少相关问题的发生，让充电变得更加透明可靠。然而，技术标准不一致也会产生问题，整个电动汽车行业都早受到困扰，不统一的标准就意味着，你必须寻找一个你的车能够进行充电的停车场，而且道路充电解决方案也将不可行。这或许是制住泰斯拉前进步伐的原因。
锂空气电池
IBM和其他企业正在研发一项很有前景的技术：锂空气电池，其能处理一个油箱的能量密度。在过去的几年里，冶金术取得了重大进步，让基于锂空气技术的电池能够在10年内实现。如果说，电池拥有与油箱同样的能量容量，且体积大小相同，可以用来替换泰斯拉Tesla S的巨型电池组，你或许会开这辆车，然后让里程翻两番。开行到1000英里时，你不需要过多的担心充电插头。更有可能的是，工程师们或许会使用一个更小的电池，让电动汽车更轻售价更低。加上充电插头更加普遍，这项几乎或许会成为电动汽车行业的规则颠覆者，显示出比汽油更高的能源效率。
超级电容器（Supercapacitors和ultracapacitors）
超级电容器是电池的替代，事实上其已经应用于商用车辆之中。电容器是固态的，其拥有一个近乎无限的生命周期，能够充放电数千次，速度快于锂离子电池，且不会造成损伤。在某种程度上，电容器和普通的电池就像是闪存和硬磁盘，最开始闪存表现较好，但却比硬磁盘更贵。甚至iPod最开始都有硬驱动。但是随着闪存价格下滑，其市场占有率越来越高，现在硬磁盘正在被市场淘汰。
不幸的是，电容器仍处于转变初期。现在，电容器价格非常高昂，经过一段时间会充电失败，而且其能源密度比电池还低。从这些看到，电容器或许不会在在近期内解决电动汽车的能源问题，但是就像闪存，其价格有望大幅下跌，能量密度会增加，自放电率也会有所改善。不过，电容器已经在混合动力装置中采用，用户可以分分钟内为电容器快速充好电，然后电容器会在用户开车的途中自动为电池充电。
下一个泰斯拉在哪里？
这里我指的不是泰斯拉这间公司，而是泰斯拉这个人，他很早变离世，而致他死亡的或许是一种神秘的死亡射线，而他生前曾研究过广播能量。英特尔和其他企业一直在努力打入这个领域，但是其要想实现在个人电子设备上运行，还有很长的路要走，要想要该技术能够在汽车上使用，或许还要等上数十年。不过，一旦该技术研发成功，其将能够永远解决电动汽车的电池问题，到时，我们将生活在一个电气世界，而我们也会遭遇到一些健康问题需要解决：虽然在黑暗中发光这个想法很酷，但是我们需要避开“死亡射线”这个部分。无论如何，我都认为，广播能量将预示着电动汽车永恒时代的最终到来。
