As the world transitions toward greener solutions to combat climate change, electric vehicles (EVs) have emerged as the frontrunners in sustainable transportation. However, the widespread adoption of EVs has long been hindered by key challenges such as range anxiety and limited charging infrastructure. Sweden, a country renowned for its progressive environmental policies and technological innovation, is poised to address these issues with a groundbreaking project: the construction of the world’s first permanent electric vehicle charging highway.
This pioneering project, part of Sweden’s broader commitment to sustainable development, represents a significant leap forward in the transportation sector. By enabling EVs to charge while driving, this electrified highway eliminates two of the most significant barriers to EV adoption—long charging times and reliance on stationary charging stations.
Set for completion by 2025, the highway is expected to revolutionize EV infrastructure, not just in Sweden but worldwide. It offers a glimpse into a future where electric mobility is seamless, convenient, and fully integrated into everyday life.
A Revolutionary Concept: Dynamic Wireless Charging
At the heart of Sweden’s electrified highway lies a transformative technology known as “dynamic wireless charging.” Unlike traditional charging methods, which require vehicles to stop at designated stations to plug in, dynamic wireless charging allows EVs to recharge their batteries while in motion.
The system involves embedding induction coils beneath the road surface, which generate an electromagnetic field. EVs equipped with compatible receivers can draw power from these coils as they travel over them, recharging their batteries effortlessly. This innovative approach provides several key benefits:
- Eliminates Downtime: Drivers no longer need to stop for lengthy charging sessions, saving time and improving the convenience of EV travel.
- Smaller Batteries: Continuous charging reduces the need for large, expensive battery packs, making EVs more affordable for consumers.
- Increased Range: Dynamic charging ensures that vehicles can travel long distances without fear of running out of power.
This method contrasts with static charging, where vehicles must remain stationary to connect to a power source. By allowing charging to happen during normal driving, Sweden’s electrified highway promises to make EVs a more practical and attractive option for both individual drivers and commercial fleets.
From Pilots to Permanence: Sweden’s Path to Electrified Roads
Sweden’s journey toward building a permanent EV charging highway began with a series of pilot projects aimed at testing the feasibility of electrified road systems.
- The First Steps:
In 2018, Sweden inaugurated the world’s first electrified public road—a 1-mile stretch near Stockholm equipped with conductive rails. Electric trucks and buses were powered on the move by lowering a movable arm that connected to the rails embedded in the road. - Inductive Charging Tests:
Another notable pilot took place in Visby, a city on Sweden’s Gotland island, in 2020. This project involved a wireless electric road that used induction technology similar to what the permanent highway will employ. Heavy vehicles, such as buses and trucks, successfully recharged while driving over the road, demonstrating the technology’s practicality and safety.
These pilot projects provided valuable insights into the technical, logistical, and economic aspects of electrified road systems. They also confirmed that dynamic charging could be scaled up to support a permanent highway.
The E20 Highway: Sweden’s Bold Vision
The permanent electrified highway currently under construction is located on the European route E20, connecting the cities of Örebro and Hallsberg in central Sweden. This 13-mile stretch was chosen strategically for its high volume of commercial traffic and proximity to major logistics hubs.
Construction began in 2023 and is expected to conclude in 2025. The chosen dynamic charging method will involve embedding induction coils beneath the left lane of the highway. These coils, placed every 10–30 feet, will wirelessly transmit power to compatible EVs driving above them. Sensors will detect the presence of vehicles and trigger power delivery, ensuring efficient energy use.
This innovative infrastructure will serve as a blueprint for future electrified highways, both in Sweden and abroad.
Environmental and Economic Benefits
Sweden’s electrified highway is more than just a technological marvel—it is a critical step toward achieving the country’s environmental and economic goals.
- Reducing Carbon Emissions:
Transportation accounts for a significant portion of global greenhouse gas emissions. By electrifying highways, Sweden aims to reduce carbon emissions from heavy vehicles by up to 90%. This aligns with the European Union’s target of achieving zero CO2 emissions from new cars by 2035. - Lowering EV Costs:
Dynamic charging reduces the need for large battery packs, which are among the most expensive components of EVs. Research from Sweden’s Chalmers University of Technology suggests that dynamic charging could decrease battery size requirements by up to 70%. This would lower manufacturing costs and make EVs more affordable for a broader range of consumers. - Boosting Economic Growth:
The construction and maintenance of electrified highways will create jobs in sectors such as engineering, construction, and technology development. Additionally, increased EV adoption could stimulate demand for related industries, such as renewable energy and battery production. - Enhancing Accessibility:
Electrified roads could make EVs more practical for people living in rural areas, where charging stations are often scarce. By integrating charging infrastructure directly into highways, Sweden ensures that sustainable transportation is accessible to all.
Scaling Up: A Nationwide Network
The E20 highway is just the beginning. If the project proves successful, Sweden plans to expand its electrified road network to over 3,000 miles by 2035. This ambitious initiative would cover most of the country’s major transportation corridors, ensuring that EV drivers have access to charging infrastructure wherever they go.
The Swedish Transport Administration estimates that electrifying 25% of the country’s roads would be sufficient to support a fully functional electric road system. This targeted approach balances cost-effectiveness with maximum impact, paving the way for widespread adoption of dynamic charging technology.
Global Momentum: Sweden Inspires the World
Sweden’s leadership in electrified roads has inspired other countries to explore similar initiatives. For example:
