Sweden Begins Testing World's First Electrified Road: Cars Can Be Charged While Driving

- Jan 08, 2020-

According to foreign media reports, Sweden has built the world's first electrified road, which can be used to charge cars when cars are driving on it. Supporters of the project, Vattenfall and Elways, said the project has the potential to help reduce the high cost of electric vehicles.


The project, called "eRoadArlanda," received funding from the Swedish state and cost about 50 million crowns (approximately $ 5.82 million). The project's executors will use a modified electric truck to transport cargo from Arlanda Airport in Stockholm to a nearby logistics center to test the technology.


The road is 2 kilometers long (about 1.24 miles), and an electrified track is installed on the asphalt road. When the truck is on the road, the electrified track will charge the truck. The truck is equipped with a movable arm that can detect the position of the track on the road and the position of the charging point when the vehicle is overtaking or approaching a parking point.


This system can also calculate the energy loss of the vehicle, thereby subdividing the electricity bill to the head of each car and user.


Elways CEO Gunnar Asplund said that charging while driving meant that electric vehicles no longer needed large-capacity batteries, which also ensured that electric vehicles had enough energy to travel a longer period of time. distance. Battery costs account for about half of the total cost of electric vehicles.


"This technology provides unlimited mileage. Electrified roads allow electric cars to use smaller batteries and make electric cars cheaper than traditional cars that use gasoline," he said.


Espland said that the Swedish government is satisfied with the current results, and the only problem is that a lot of dust is often accumulated on the track. (It is said that the problem has been solved now.)


Elways has been awarded a patent for electrical rail technology, a member of the Swedish consortium supporting the eRoadArlanda project. Other members of the consortium also include the infrastructure company NCC and the utility Vattenfall, which provides the project from the State Grid electric power.


Vattenfall spokesman Markus Fischer said: "This road enables electric vehicles to travel a long distance without the need for large, expensive and heavy batteries." He added that installing a newer arm in a new car is a better option than retrofitting Existing models are more affordable.


Vattenfall said in a statement that electrified roads could reduce CO2 emissions from trucks. At present, the carbon dioxide emissions of trucks account for about 25% of total road traffic emissions.


It added: "The investment cost per kilometer is estimated to be lower than the cost of using overhead lines, and the use of overhead lines will also have an impact on the landscape."


The eRoadArlanda project began testing in April and will last at least 12 months to test the use of electric trucks in different weather conditions.
