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(dá)機(jī)場和鄰近的某個(gè)物流點(diǎn)。

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

這條充電公路是朝著瑞典的長期能源戰(zhàn)略和對抗氣候變化舉措邁進(jìn)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桿，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(jié)50米的路段構(gòu)成。每節(jié)路段獨(dú)立供電，只給在該節(jié)路段上行駛的車輛充電。為確保安全，車輛停下來時(shí)，電力自動(dòng)切斷。
