The system being this road is called “dynamic charging”. Don’t worry about being electrified by the road. There is no electrical current passing through the surface of the road. How it works is that there are two tracks of rail in the road that come in contact with a movable arm under the electric vehicle.
To charge, the car has to run over those tracks and it is disconnected whenever it switches lanes or moves away from the track. So, the road surface itself is safe. An explanation from the CEO of the consortium executing the road: The technology is an innovative combination of a regular road, rail track and a tram overhead wire flipped upside down. That kind of thing. This is a tram: This electrified road technology can be implemented as a dedicated lane in a 4-lane highway, so users of electric cars who need to top up can do so without stopping. Dear people, innovation is sweet to see unravel. To infinity and beyond!
