Road infrastructure
Inductive equipment is placed beneath the road surface at the centre of the traffic lane. The carriageway remains clear of exposed charging hardware.
Wireless road technology
Four systems, one continuous energy path.
Road infrastructure, vehicle receivers, real-time communication and management units work together to transfer energy without exposed rails or overhead wires.

Integrated beneath the laneThe transfer equipment is designed around a road that remains open to compatible and conventional vehicles.
The technology includes
The complete transfer chain
No single component makes an electric road. Power must move through a coordinated system that identifies the vehicle, activates the appropriate road segment and controls delivery.
Vehicle receivers
A compatible receiver mounted beneath the chassis captures energy from the magnetic field and converts it into electricity for the vehicle.
Communication system
Real-time communication confirms compatibility and position so that only the relevant segment is energised when it is needed.
Management units
Power electronics transmit and regulate energy to the road infrastructure. Depending on the installation, units may sit above ground or underground.
Transfer sequence
From supply to moving vehicle
The process is segmented and controlled. Equipment is not intended to energise the entire road continuously.
Prepare power
The management unit conditions electrical energy for safe, controlled transfer.
Confirm the vehicle
Communication identifies an authorised receiver and its position over the lane.
Activate the segment
Only the road section beneath the compatible vehicle is selected for transfer.
Receive energy
The chassis-mounted receiver converts the field into usable electrical power.
Designed for movementDynamic transfer can complement stationary charging across a vehicle's duty cycle.
Road integration
Built as infrastructure, operated as a system
The physical coils are only one layer. A practical installation must also account for road construction, drainage, resurfacing, electrical access, vehicle clearance and ongoing monitoring.
Its control layer coordinates road and vehicle so that power is available at the right place and time while ordinary traffic continues to use the same surface.
- Below-surface installation: charging components do not create an exposed track in the lane.
- Segmented operation: activation follows the compatible vehicle rather than energising an entire route.
- Mixed traffic: unequipped vehicles can continue using the road without receiving energy.

Technical FAQ
Practical questions
Key distinctions for understanding how an inductive electric road operates.
Visit the full FAQDoes every vehicle receive energy?
No. A vehicle needs a compatible receiver and appropriate system authorisation. Other vehicles can use the same road normally.
Are the road segments always active?
No. The communication and control systems activate relevant sections when a compatible receiver is correctly positioned above them.
Where is the vehicle receiver installed?
The receiver is mounted beneath the vehicle chassis with a design suited to the required clearance and vehicle configuration.
Can management units be installed underground?
Yes. Management units may be positioned above ground or underground according to the road, electrical and maintenance design.
What happens to the transferred energy?
The receiver converts the magnetic field into electricity that can support propulsion or charge onboard storage, depending on the vehicle system.
Does dynamic charging remove the need for batteries?
Not necessarily. Onboard storage can support travel away from equipped roads. Battery requirements depend on route coverage, duty cycle and charging strategy.
