Stretch of road outside Stockholm transfers energy from two tracks of rail in the road, recharging the batteries of electric cars and trucksThe world’s first electrified road that recharges the batteries of cars and trucks driving on it has been opened in Sweden. About 2km (1.2 miles) of electric rail has been embedded in a public road near Stockholm, but the government’s roads agency has already drafted a national map for future expansion. Energy is transferred from two tracks of rail in the road via a movable arm attached to the bottom of a vehicle. The system is able to calculate the vehicle’s energy consumption, which enables electricity costs to be debited per vehicle and user. The “dynamic charging” – as opposed to the use of roadside charging posts – means the vehicle’s batteries can be smaller, along with their manufacturing costs.
