The world's first electrified road that recharges the batteries of cars and trucks on the run has been opened in Sweden.
日前，瑞典开通了全球首条“充电公路”，能给行驶中的汽车和卡车的电池充电。
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.
这条电轨嵌在斯德哥尔摩附近的一条公路上，绵延两公里连接斯德哥尔摩阿兰达机场和邻近的某个物流点。
This electrified road is an important step forward in Sweden's long-term energy strategy and its efforts to combat climate change.
这条充电公路是朝着瑞典的长期能源战略和对抗气候变化举措迈进的重要一步。
The road transfers electricity from an underground rail into the batteries of cars through a flexible arm attached to the charging vehicle.
该公路通过充电汽车上的一根可弯曲杆，将电能从地下轨道传输至汽车的电池中。
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，充电公路每公里约耗资100万欧元, 比安装等距的有轨电车轨道便宜了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.
这条充电公路由许多节50米的路段构成。每节路段独立供电，只给在该节路段上行驶的车辆充电。为确保安全，车辆停下来时，电力自动切断。
