At the beginning of March, the world’s first stretch of road will open with inductive charging of electric cars on the island of Gotland in Sweden. The project is implemented with technology developed by the Israeli company Electreon, writes Teknisk Ukeblad.

-We want to show that our system is very competitive and can even be cheaper than power transmission via a fixed connection, says Stefan Tongur, business developer at Electreon.

A half kilometer long test section is being built between Visby and Visby Airport. A heavy truck and an airport bus must test the rechargeable road. The test is performed by the Swedish Transport Administration on Gotland – the test will last until the spring of 2022.

It will be the world’s first comprehensive test of inductive charging on public roads. In the past, the technology had a significantly higher cost level than other charging solutions in the infrastructure, but the Israeli company has found a solution that can compete on price. The reason for this is the idea of ​​building on a large scale in contrast to previous induction charging systems.

-In addition, the technology is easy to manufacture and requires no major intervention in the roadway during installation, says Tongur.

Charging is done by the receivers under the vehicles picking up power from the copper coils built into rubber mats under the asphalt. Since the rubber mats are a few centimeters below the asphalt, the carriageway will look like a normal road.

According to Electreon, the solution has an efficiency of between 87 and 92 percent. The distance from the receivers to the copper coils can be up to 24 centimeters. The technology will work whether there is snow, ice or gravel on the road.
