Engineering#15 in June 2026 EditionDynamic wireless power transfer for electric heavy-duty vehicles with 94% transmission efficiency at 100 km/h

OPENSTEM EDITORIAL SUMMARY
What the research examines
Electrical engineers construct a segmented roadway magnetic resonance wireless power transfer track delivering 150 kW to a traveling electric semi-truck at highway speeds. A real-time tracking inverter matches resonant frequencies within 5 milliseconds.
Why it may matter
Enables long-haul electric freight trucking without requiring massive, heavy, and environmentally costly battery packs.
What to examine carefully
High civil infrastructure installation costs for embedding magnetic coils into highway asphalt corridors.
Editorial scope: This is a concise, independently written introduction based on the publisher information, not a full systematic review or independent replication. It must not replace reading the original methods, limitations and conclusions.
STUDENT RESEARCH LENS · ORIGINAL OPENSTEM NOTES
Try a small, reproducible follow-up
Model mutual inductance and efficiency variation between circular and rectangular magnetic ferrite coil topologies under lateral misalignment.
Questions to investigate
- How was electromagnetic field radiation shielded to comply with ICNIRP public safety thresholds?
- What switching losses were measured in the Silicon Carbide (SiC) resonant inverter modules?
These are independently proposed educational investigations, not activities that the original research authors claim to have completed.
