When driving an electric car, care must be taken not to drain the battery. Imagine not having to interrupt your ride in the future to charge your car. Wireless charging roads are no longer just science fiction, but real projects that are being tested. Wireless charging roads will not be a rarity, but will be built around the world.
Wireless charging roads in Norway
In order to reduce the emissions produced, Norway has introduced a measure that all cars sold after 2025 must be electric. With that came an interesting charging concept. Taxis in Norway are equipped with a wireless charger, which is located under the car. This unit works on the principle of electromagnetic induction.
When this unit is in close contact with the charger, which is located under the road, the car can be charged while driving. This technology is currently available for taxis, but is expected to spread to all cars. Such charging saves many hours of time each month. Below you can watch a video that demonstrates this technology.
Charging roads in Indiana
One of the first countries where charging roads will be built is Indiana. The Indiana Department of Transportation (INDOT) plans to place electrified coils under the road surface and the charging system is to operate in a similar way to the wireless charging of telephones. Of course, cars will have to be equipped with a receiving coil that will charge the battery in the vehicle. The project was created on the basis of cooperation between INDOT and Purdue University. The project will use innovative magnetizable concrete – developed by the German startup Magment GmbH.
“Indiana is known as the Crossroads of America and we’re committed to fortifying our position as a transportation leader by innovating to support the emerging vehicle technology,” Governor Eric J. Holcomb said. “This partnership to develop wireless charging technology for highways sends a strong signal that Indiana is on the leading edge of delivering the infrastructure needed to support the adoption of electric vehicles.”
“As electric vehicles become more widely used, demand for reliable, convenient charging infrastructure continues to grow, and the need to innovate is clear,” INDOT Commissioner Joe McGuinness said. “We are excited to partner with Purdue and Magment to explore incorporating wireless charging technology into highway infrastructure.”
Technology that will be available worldwide
In the first phases, charging roads will be tested. It is necessary to find out how the technology will work in normal operation and how it can charge even large trucks. When testing is complete, charging roads will be built. Even in other countries, this technology is being tested. The construction of charging roads is also planned in Sweden. This technology will contribute to a more sustainable future and greater use of electric vehicles.
