Electric-car charging road opens in Sweden
The 1.2-mile-long stretch of electrified road was developed by eRoadArlanda – a consortium including vehicle manufacturer DAF, property developers, technology companies and academic institutions. It employs a system whereby energy is transferred to specially designed cars and trucks from an electrified track in the surface of the road. A connection to the underneath of the vehicle is made by a movable arm, which automatically detects when the rail is near and lowers to begin charging. eRoadArlanda claims that the in-road system is cheaper than overhead charging and has several other advantages. It can be implemented in the existing infrastructure, it works for both passenger cars and heavy vehicles, which overhead charging doesn't, and it's very discreet from an aesthetic point of view.
