In regards to speed limitations for vehicles on the electric roadway, our system has been successfully tested with speeds of up 50 mph (80 km/h), but this is mainly due to limitations of the road’s speed limit itself in the areas where the technology has been deployed. In Sweden, a heavy-duty truck drove at this speed from the electric road at a stable power level of 100 kW of charging.
Based on these tests, charging efficiency remains constant regardless of speed, though the speed would impact the amount of energy being transferred overall, since at faster speeds, less time is being spent over the roadway to charge.
The system itself is designed to support higher speeds and high speed tests are planned to be completed 2023-2024 for up to 120 km/h).
