Title:
ENERGY TRANSMISSION OPTIMIZATION OF FOREIGN OBJECT MONITORING AND MAGNETIC SATURATION
Document Type and Number:
WIPO Patent Application WO/2017/063135
Kind Code:
A1
Abstract:
When a transmitting end mistakenly considers a foreign object as a receiving end, not only an energy loss but also security issues, such as an explosion caused by an excessive instantaneous current, are caused. Therefore, the foreign object, which is not removed through monitoring, may interfere with the normal operation of a wireless charging system. Magnetic saturation is a physical property of magnetic materials, and the voltammetric behavior thereof may cause confusion in a foreign object monitoring process and produce an energy loss. Provided is a method for monitoring a foreign object in a wireless charging process, thus a loss caused by the foreign object and magnetic saturation is avoided, and energy transmission of a wireless charging system is optimized.
