The Road Will Charge The Battery While Driving

Being fuel efficient and environment friendly, the production and use of electric vehicles is currently increasing worldwide. But these cars can only be charged at home or at certain places. As a result, many people are in danger when the charge of the car runs out during a long trip. To solve this problem, Sweden is building e-motorways or permanent electrified roads capable of charging batteries while electric cars are running.

Engineers are optimistic about an e-motorway capable of charging electric cars. And so Sweden is turning an entire highway into a permanently electrified road. The batteries of electric cars and trucks will be automatically charged while driving on this electric road. As a result, electric vehicles with small batteries with dynamic charging facilities will be able to travel long distances continuously.

Regarding the e-motorway, Jan Pettersson, director of strategic development at Sweden's Trafficverket, said, "We think this electric system will prevent carbon emissions in the transportation sector." We are working on several solutions. A highway named European Route E20 has been selected for the construction of this motorway. The highway is located between the three major cities of Sweden, Stockholm, Gothenburg and Malmö.

The method of charging electric vehicles on the E20 highway is yet to be determined. However, three types of charging systems can be used on highways namely catenary system, conductive (ground-based) system and inductive system. A catenary system would supply electricity to buses or trams through overhead cables. Only heavy vehicles can use this method. On the other hand, in the conductive charging method, the vehicle is charged from an electrical conductor such as a rail track. Both heavy and private vehicles can be charged using this method. The inductive charging method places battery charging parts under the road. As a result, the battery of the electric vehicle starts charging through a special type of coil when passing over a certain place on the road.

According to the researchers, it is not necessary to electrify all roads in Sweden to implement these new methods of charging electric cars. Only 25 percent of the roads will have this facility introduced. Dr. Chalmers University of Technology, Sweden, physical resource theory department researcher. Wasim Shoman said that currently research is being done on electric road technology in Italy, UK, USA and India. France has already started a test program to build such a road.
