Several countries around the world are increasing their investment in electric vehicle solutions, starting with new models, batteries with greater autonomy, charging stations and tax incentives. Sweden has just announced that it will become first country to introduce a permanent electric roadcapable of recharging electric vehicles while they are in motion.

The Swedish Transport Administration Trafikverket is responsible for the project. The site chosen for the construction of the permanent electric road is also very interesting: the E20 highway on the 21 km route from Halsberg to Örebro. This section of the highway is located between the two largest cities in Sweden, the capital Stockholm and Gothenburg. The region has a large flow of vehicles, from trucks, motorcycles and cars, and this should benefit a large number of drivers. The permanent electric road is reportedly in the final stages of planning. ABOUT the project must be completed and presented to the public in late 2025 or early 2026.

Electric road technology was not selected

Trafikverket has not yet decided which technology will be used to recharge electric vehicles traveling on the highway. The Swedish Transport Administration can choose between three different systems: Air conductive, ground conductive and ground inductive charging. With conductive air charging, energy is transferred from the wires to the vehicle through the pantograph. The first option is not worth choosing, as it is more suitable for trucks or large vehicles.

The other two options are more similar, where the battery is charged through the ground, either on special rails by the conductive method, or with power transmission using the inductive method. Regardless of the technology chosen, Sweden wants to invest heavily in road electrificationwith a plan to implement 2,000 km of electric roads by 2030.

Sweden wants to electrify its fleet

Road construction should also help reduce demand for electricity during peak hours, acting as an alternative to home charging. In addition, a study by the Chalmers University of Technology in Gothenburg shows that dynamic charging (on the move) can help reduce battery size by about 70% and reduce vehicle production costs. Study co-author Sten Karlsson says electrified roads reduce the need for large batteries with long range. “This will reduce the need for raw materials for batteries, and an electric car can also become cheaper for the consumer.”

Finally, the same study also indicates that only 25% of the national roads (the busiest ones) will need to be electrified to keep Sweden’s EV fleet always charged. This is a very interesting idea, let’s hope that the country will be able to effectively implement the novelty.
