Tesla moves forward on Wireless Charging for vehicles
Tesla has published a new patent on October 1, 2026, detailing a wireless charging pad that detects foreign objects across temperature variations. The system uses inductive coils in resonant tanks, exciting them with frequencies near the nominal resonance. By monitoring changes in coil resistance and inductance, the detector distinguishes metal obstructions from temperature‑induced shifts, ensuring safe, efficient charging. Tesla claims the Cybercab wireless charger achieves over 90% efficiency and will support its autonomous Cybercab and Robotaxi fleets.
