Norway has unveiled the world’s first wireless charging road for electric vehicles (EVs). The innovative technology, developed by the hi-tech company Electreon Wireless, promises to revolutionize the way electric buses operate by enabling them to charge while in motion. This pilot project, located in Trondheim, is set to be a game-changer in reducing carbon emissions and promoting green energy.
Electreon’s road charging system is a marvel of modern engineering. It features specialized copper coils embedded just beneath the road surface. These coils wirelessly transfer energy to vehicles equipped with compatible receivers, allowing them to charge on the go. The new 100-meter segment in Trondheim is the first of its kind and will be under assessment for about a year.
The project sees collaboration between multiple stakeholders, including the Norwegian government, which is funding the initiative to the tune of 22.4 million Norwegian kroner (approximately 2.12 million US dollars). The tests will involve three electric buses from the Chinese manufacturer Yutong and a fourth bus from another Chinese company, Higer. This international cooperation highlights the global effort to tackle climate change and transition to sustainable energy sources.
“Inductive charging of vehicles in motion can be an important technology for the transport sector. This project will be most relevant for buses and lorries. The project will provide important knowledge for the coming bus tender in the greater Trondheim area, in operation by 2029. We want to contribute to reducing the barriers for making use of inductive charging under challenging winter conditions and learn how to make it successful”, says Konrad Pütz, Director of Transportation, Trøndelag County authority.

One of the key advantages of this technology is its potential to enable continuous bus operation without the need for charging stops. By allowing buses to run uninterrupted throughout the day, the system could significantly reduce downtime and enhance the efficiency of public transport. Moreover, the reduced need for stationary charging could lead to a substantial decrease in carbon emissions, aligning with global environmental goals.

The pilot program in Trondheim will also test the resilience and effectiveness of the charging system in severe winter weather. Trondheim’s harsh winter conditions present a unique challenge, making it an ideal testing ground for assessing the technology’s durability and reliability. Successful operation under these conditions would demonstrate the system’s robustness and viability for use in other regions with similar climates.
If successful, the Trondheim pilot could pave the way for broader adoption of wireless charging roads across Norway and potentially around the world. This technology could be a vital component in the infrastructure required for a fully electrified transportation system. By reducing the dependency on traditional charging stations, cities could see a decrease in the space and resources dedicated to EV charging, making urban planning more efficient and sustainable.
