瑞典開通世界首條充電公路

The world's first electrified road that recharges the batteries of cars and trucks on the run has been opened in Sweden.

日前，瑞典開通了全球首條“充電公路”，能給行駛中的汽車和卡車的電池充電。

The electric rail has been embedded in a public road near Stockholm, linking Stockholm Arlanda airport to a nearby logistics site over a stretch of 2 km.

這條電軌嵌在斯德哥爾摩附近的一條公路上，綿延兩公里連接斯德哥爾摩阿蘭達機場和鄰近的某個物流點。

This electrified road is an important step forward in Sweden's long-term energy strategy and its efforts to combat climate change.

這條充電公路是朝着瑞典的長期能源戰略和對抗氣候變化舉措邁進的重要一步。

The road transfers electricity from an underground rail into the batteries of cars through a flexible arm attached to the charging vehicle.

該公路通過充電汽車上的一根可彎曲杆，將電能從地下軌道傳輸至汽車的電池中。

Each kilometer of electrified road currently costs roughly 1 million euros, 50 times cheaper than installing an overhead tram line over the same distance.

目前，充電公路每公里約耗資100萬歐元, 比安裝等距的有軌電車軌道便宜了50倍。

The e-roads are divided into 50 meter-long (164 feet) segments, which are individually powered -- and only when a car is running on that segment. To keep extra safe, power will be cut when a vehicle stops.

這條充電公路由許多節50米的路段構成。每節路段獨立供電，只給在該節路段上行駛的車輛充電。爲確保安全，車輛停下來時，電力自動切斷。
