Abstract
The disclosure generally relates to methods, system and apparatus to detect a rogue object placed on an A4WP charging pad (interchangeably, charging mat). In one embodiment, presence of a rogue object on a charging pad is detected by measuring currents and voltages from sensor circuits on PTU and apply machine learning algorithms to develop power leakage algorithm. The algorithm identifies false objects placed on the charging pad and obviates false alarm while simultaneously detecting presence of a rogue object which can damage the A4WP wireless charging system.
