Higher-power road section
Construction of a 50-metre wireless electric-road section intended to test power transfer above the level previously used in the wider road project.
Energy pilot
Testing wireless charging as one connected system.
The Gotland pilot examined higher-power transfer, static induction and vehicle integration to build practical knowledge around wireless charging infrastructure.
Completed pilot · 2021–2023
A system-level study Dynamic road charging and stationary induction were considered together rather than as isolated components.
About the pilot
From individual components to coordinated charging
The completed project brought together several measures connected with wireless electric-road technology. Funding came from the Swedish Energy Agency and the European Regional Development Fund within the Energy Pilot Gotland programme.
The work addressed how dynamic road charging, stationary induction and compatible vehicle receivers could be examined at system level. Alongside physical construction and integration, the scope included location-based case studies and analysis of test results.
Historical project information: this page describes a pilot that concluded in March 2023. It is retained to explain the original work and its technical scope.
Project scope
Six connected areas of work
The pilot combined infrastructure, charging configurations, vehicle hardware and analysis to explore more than one operating situation.
Static charging station
A stationary charging installation using the same inductive approach, supporting learning about static charging and coordination with dynamic supply.
Truck and trailer receivers
Integration of energy receivers on both truck and trailer to examine the opportunity for charging at higher power.
Loading-dock case study
A case study examining wireless charging at a loading dock and the operating questions that arise around that use case.
Stockholm case study
A separate case study used to consider the technology in another transport and infrastructure context.
Test analysis
Analysis brought observations from the technical measures together to support a clearer system-level view.
What was included
One charging principle, different operating moments
Wireless transfer may happen while a vehicle is moving or while it is stationary. The pilot explored how these modes could use a related technical foundation and how vehicle-side equipment fits into the complete system.
- Embedded wireless road infrastructure
- Stationary inductive charging equipment
- Receivers integrated with a truck and trailer
- Coordination questions across charging modes
- Case-study and test-analysis work
How the work connected
A pilot built around the full energy path
Each area addressed part of the journey from electrical infrastructure to a compatible vehicle and an observable test result.
Build
Create road and stationary charging environments using wireless induction.
Integrate
Fit suitable receiving equipment to the truck and trailer configuration.
Examine
Consider dynamic, static and loading-dock use in their operating contexts.
Analyse
Review tests and bring the separate technical questions into one system view.
Why combine the modes?
Charging needs change across a vehicle’s duty cycle
A vehicle may require energy while travelling, at a depot or during loading. Looking at dynamic and stationary induction together makes it possible to ask how common infrastructure principles could serve different parts of that cycle.
The pilot’s case studies also recognised that a technical solution has to be understood in its road, freight and site context. Route patterns, stopping behaviour, vehicle configuration and available energy infrastructure all shape the practical question.
Pilot questions
Understanding the project
Key distinctions within the historical pilot scope.
Is the energy pilot still running?
No. The documented project ran from autumn 2021 until March 2023. This page presents its scope as completed historical project information.
What was the 50-metre road section for?
It was constructed to test higher power transmission than had previously been used on the wireless road project.
Why was a stationary charging station included?
It enabled work on static induction charging and supported investigation of how stationary and dynamic charging could be coordinated at system level.
Why were receivers fitted to both truck and trailer?
The integration was intended to explore the opportunity to charge at higher power using receiving equipment across that vehicle configuration.
Did the project include only physical construction?
No. It also included loading-dock and Stockholm case studies as well as test analysis.
Does every vehicle charge on an inductive road?
No. A vehicle needs compatible receiving equipment and must meet the system’s operating and authorisation requirements.
