As electric vehicles (EVs) become more common, attention is turning to how the UK's charging infrastructure can keep pace with growing demand. While public charging networks continue to expand, new technologies are being explored to make charging faster, more convenient and more accessible.
One of the most ambitious ideas is electric roads - roads capable of charging compatible EVs while they're driving. Also known as dynamic charging roads, this technology could reduce the need for lengthy charging stops and help make electric vehicles even more practical for businesses and drivers. In this guide, we explain how electric roads work, where they're being trialled, and what they could mean for the future of EVs and commercial fleets.
What are electric roads?
Electric roads are roads fitted with technology that can supply electricity to compatible electric vehicles while they're moving or stationary. Instead of relying entirely on charging stations, vehicles receive power directly from infrastructure built into or above the road.
Often referred to as dynamic charging roads or inductive charging roads, the technology aims to reduce charging stops, improve journey efficiency and potentially allow manufacturers to build EVs with smaller batteries.
There are generally two main approaches:
Embedded dynamic charging (inductive or conductive): Electric cables or conductive rails are embedded in the road or along its surface, and vehicles draw power through a pickup system. This can be either contact-based (conductive rails) or contactless (inductive coils).
Overhead charging (catenary or overhead wires): Similar to those used by trams or electric buses, overhead lines carry current, and EVs draw power via pantographs or similar hardware.
The goal of electric road technology is to enable continuous charging, enabling shorter battery packs, lower upfront costs for EVs, and reduced reliance on stationary chargers. While technologies such as electric roads are still developing, businesses can prepare now by understanding how to prepare for the EV transition.
Why electric roads matter for the future of EVs and fleets
The potential benefits of electric roads are significant, particularly for commercial fleets, long-haul transport, and urban delivery services.
1. Reduced need for large batteries
One of the highest costs and limitations in EVs is their battery size. Consumers demand further and further range requirements for new electric vehicles, which means larger batteries. Technologies such as electric roads could also help reduce EV range anxiety, one of the biggest concerns among drivers considering switching to electric vehicles. But large batteries increase vehicle cost, weight, and charging time. Battery size and capacity are also often cited as major challenges to HGV fleets adopting alternative fuel technology. With dynamic charging, vehicles, including HGVs, could rely on smaller batteries drawing power as they drive, reducing cost, lightening loads and environmental impact. Businesses considering electrification may also want to explore whether electric cars are more energy efficient than petrol and diesel alternatives. Even with improvements in charging infrastructure, fleet managers should still understand what happens if your EV runs out of charge, helping drivers prepare for unexpected situations.
2. Less charging downtime
For businesses that rely on vehicle logistics, delivery, and field service, downtime waiting for charging can be costly. Electric roads could dramatically reduce or even eliminate that downtime, improving utilisation and efficiency.
3. Lower long-term infrastructure pressure
Instead of building thousands of static charging stations with grid upgrades, parking capacity and space constraints, electric roads embed charging into the existing road network. Over time, this could scale more efficiently, especially on busy transit corridors or delivery routes. However, we must appreciate the effort required to implement electric road technology.
4. Accelerated EV adoption and zero-emission mobility
With easier charging and reduced costs, electric roads could make EVs more accessible to a wider range of users, commercial fleets, smaller businesses, and even private drivers, helping accelerate the transition away from fossil-fuel vehicles.
How does electric-road technology work?
Here’s how the main approaches operate:
Conductive embedded rails or plates
Conductive rails or plates (metal strips) are laid either flush with the road surface or slightly raised.
EVs are fitted with a pickup shoe or under-carriage connection that draws electricity from the rail as the vehicle passes over it.
A software/control system ensures electricity flows only when a compatible vehicle is above the rail, preventing waste and maintaining safety.
Inductive charging (wireless)
Coils embedded under the road surface generate an electromagnetic field when electrified.
Vehicles have a receiver coil that picks up the field and converts it into power for the battery.
This method requires precise alignment or a broad enough coil field and is typically less efficient than conductive rails but offers better safety and fewer maintenance issues.
Overhead catenary/pantograph systems
Overhead wires carry electricity at high voltage, which is similar to electric trains/trams.
EVs designed for this system deploy a pantograph or an arm that connects to the overhead wire when driving or at set points, for example, motorway lanes.
Vehicles draw power while moving; energy can supplement battery use or directly power the motor.
Each system has pros and cons in terms of cost, efficiency, safety, maintenance and retrofit feasibility.
Where are electric roads already being used?
Although electric roads aren't yet in everyday use in the UK, several countries have already begun testing the technology through pilot projects.
Sweden is widely recognised as one of the pioneers, opening one of the world's first electric roads in 2018. Since then, the country has trialled both conductive rail systems and overhead charging for heavy goods vehicles, with ambitions to expand the network over the coming decades.
Germany has focused on overhead catenary systems for HGVs, testing electrified motorway sections that allow compatible trucks to draw power while driving.
France, Italy, Israel and the United States have also launched smaller-scale trials using wireless inductive charging or conductive road technologies.
These projects are helping governments understand installation costs, maintenance requirements and the real-world benefits before committing to larger national rollouts.
Current state trial projects and challenges
While electric roads are receiving increasing attention, the UK has not yet committed to a nationwide rollout.
The UK Government and organisations such as National Highways have previously explored the potential of dynamic charging through research programmes and feasibility studies, particularly for freight transport. However, current investment remains focused on expanding the public EV charging network and supporting the transition to zero-emission vehicles.
Industry experts generally see electric roads as a longer-term solution rather than an immediate replacement for rapid charging infrastructure. If future pilot schemes prove successful overseas, similar projects could become more common on UK freight corridors, strategic roads and dedicated bus routes.
The key barriers include:
High infrastructure cost: Embedding conductive rails or inductive coils, or installing overhead wires, requires significant upfront investment and roadworks, making it difficult to retrofit existing road networks at scale.
Vehicle compatibility: EVs must be specially equipped to draw power, meaning older vehicles or many current models would not benefit. This complicates adoption, especially for consumer markets.
Safety and maintenance concerns: Ensuring that embedded electrical infrastructure remains safe in varying weather conditions (rain, snow, ice), is durable under heavy traffic and can be maintained without major disruption.
Standardisation: Without industry-wide standards for charging voltage, rails/coils, and connectors, there is a risk of fragmentation. To be viable, electric roads need standardised protocols, safety measures, and consumer trust.
Regulation and planning: Governments and local authorities need to coordinate planning, funding, environmental impact assessments and long-term maintenance.
According to the UK Government, the number of public EV charging devices continues to grow each year, with investment currently focused on expanding rapid and ultra-rapid charging infrastructure. While dynamic charging technology remains under development, many experts believe it could eventually complement not replace the UK's existing charging network.
What electric roads mean for businesses and EV fleets
For businesses that depend on vehicles, especially commercial fleets and delivery services, electric roads hold particular promise. Here’s how companies could benefit:
Lower total cost of ownership (TCO)
Smaller battery packs, reduced charging downtime, and savings on fuel/electricity all translate into lower TCO for EV fleets. Over time, this could make EVs more affordable and practical. In the meantime, following best practices for efficient and safe EV charging can help businesses maximise vehicle availability.
Better utilisation and higher efficiency
Fleets could operate longer hours with less “dead time” for charging. For example, a delivery van could keep working through the day without needing to stop mid-route, improving turnaround times, capacity and profitability.
Competitive advantage for early adopters
Businesses that plan and invest in compatible EVs or adapt fleets may benefit early, gaining cost savings and a greener image before others catch on.
Environmental and regulatory benefits
As emissions regulations tighten and environmental compliance becomes more important, fleets using electric-road compatible EVs would be ahead of the curve, reducing emissions, potentially qualifying for clean-fleet incentives, and enhancing corporate responsibility credentials.
What still needs to happen before electric roads become mainstream?
For electric roads to become a viable, widespread reality, several things need to align:
Governments and infrastructure planners need to support pilot schemes and fund infrastructure upgrades (roads, energy grid, maintenance).
Industry stakeholders, vehicle manufacturers, charging-technology providers, and regulatory bodies must define standards for charging infrastructure, safety, and compatibility.
Fleet operators need to evaluate return on investment carefully, factoring in retrofit costs, adoption of new hardware, and long-term savings.
Awareness and planning: both public and private sectors must embrace the concept early to ensure smooth rollout and avoid fragmentation.
Are electric roads a viable option for the future of EV travel?
Potentially, yes.
Electric roads promise to overcome some of the biggest barriers to EV adoption: battery cost, charging downtime, and infrastructure pressure. For commercial fleets and businesses, the benefits could be transformational: reduced costs, higher efficiency, and easier compliance with environmental standards.
However, widespread implementation will not happen overnight. It requires coordinated action from government policy and infrastructure investment, to vehicle manufacturer cooperation and industry standards. Until then, electric roads remain an exciting possibility rather than a guaranteed future.
For businesses evaluating fleet electrification, it’s worth watching developments closely. Planning for compatible vehicles, infrastructure, and incentives may position you favourably when electric roads eventually gain traction. For more savings on your EV, it may be worth looking into an EV charge card.
