充电新科技:边开车边充电有希望了
A System That Delivers Electricity Wirelessly To a Moving Target
Wireless charging is already a thing (in smartphones, for example), but scientists are working on the next level of this technology that could deliver power over greater distances and to moving objects, such as cars.
无线充电已经成为一种技术(例如在智能手机中),但是科学家们正在研究这种技术的下一个阶段,这种技术可以在更远的距离上传输能量,并且可以传输到移动的物体上,比如汽车。
Imagine cruising down the road while your electric vehicle gets charged, or having a robot that doesn't lose battery life while it moves around a factory floor. That's the sort of potential behind the newly developed technology from a team at Stanford University.
想象一下,当你的电动汽车充电时,你在公路上行驶,或者有一个机器人在工厂里移动时不会没电。这就是斯坦福大学一个团队开发的新技术背后的潜力。

基本原理就是在路面下埋入线圈,连接上电网,当汽车驶过时就会共振,产生磁场将电力持续不断地传输给电池(电场耦合)。需要的主要成本是路面的维护。
利用路面的脑洞不限于:
给路面铺上太阳能板;让路面发光取代路灯;现在又多了一个——巨大的无线充电器
