CNN News: 无线充电新前景

As gas prices have gone lower in the U.S., it has generally meant lower sales for electric cars.

随着美国天然气价格下降，这也就意味着，电动车的销量也会降低。

More Americans have been going with gasoline powered engines. Part of the reason: most electrics, with the exception of the more expensive Tesla brand don`t go that far on a charge. A gas powered car could drive more than 300 miles on a full tank of gas. Most electrics can`t go 100 miles before needing to recharge.

越来越多的美国人在使用汽油发动机。部分原因是，除了昂贵的特斯拉品牌外，大多数电动车一次充电并不能行走的距离不如没有汽油发动机车辆行走的距离。加满天然气的汽车可以行走300英里，而多数的电动车辆一次性充电只能行走100英里。

It`s practically instinct. The light comes on and you search for the nearest gas station. Every once in a while, panic sets in, but we usually know fuel is close by. The problem: oil is not sustainable. A solution: electric, but it has its physical limitations.

几乎是出于本能。警示灯亮了，你就会寻找最近的加油站。每隔一段时间，恐慌就会袭来，但是我们知道燃料就在附近。但问题是，油是非可持续能源。解决方案：电，但是电也有物理限制。

The biggest challenge right now is what we call range anxiety. It means people are really worried about this new technology and they feel like they`re stranded at some point, right? Battery is empty and they can`t go any further.

现在所面临的最大的难题就是我们所说的里程焦距。这意味着人们真的担心这项新技术，他们觉得自己陷入了某个困境。电池没电了，不能再继续前进了。

Right.

对的。

And that is often the number one reason why they will not buy an electric vehicle. This technology could completely revolutionize that.

这是很多人不会购买电动汽车的首要原因，但是这项技术会彻底革新。

The technology Claus is referring to is called dynamic wireless charging. It works just like the wireless internet, but instead of getting you online, it charges your car as you drive.

克劳斯将这项技术称为无线充电家属。它就像无线互联网一项，但这样技术不会要你上线，而是在你开车的时候，给汽车充电。

Oak Ridge National Laboratory is a transportation testing facility run by the U.S. government. Their mission is to solve the world`s transportation problems and that means convincing automakers, consumers and taxpayers that it`s worth it to rip up America`s interstates.

橡树岭国家实验室是一个由美国政府管理的运输试验装置。他们的任务是解决世界运输问题，这意味着说服汽车制造商、消费者纳税人相信需要将美国的州际公路重新整顿。

How do you retrofit roads to become wireless charging stations?

如何将道路改成无线充电站呢?

One of the current scenarios is that the coil could actually be embedded in the roadway. Those are the part that would be placed in the roadway or placed in the parking opportunity.

现在的一种情景是将线圈潜入道路中。另外一部分线圈将会马路上或者装在停车处。

So, this would be embedded in the road?

那么，线圈将嵌入在路上?

You actually have flashed at ground level.

但实际上，你开车时是一闪即逝的。
