异物检测方法及装置、无线充电控制方法及装置
摘要：
本发明公开了一种异物检测方法及装置、无线充电控制方法及装置。本发明的异物检测方法包括：在利用无线充电系统的原副边进行无线充电的过程中检测无线充电系统当前的第一开关频率；获取所述无线充电系统的原边与副边之间不存在异物的情况下所述无线充电系统的第二开关频率；当所述第一开关频率与所述第二开关频率的差值在预设范围内时，判定所述无线充电系统的原边与副边之间存在异物；本发明的异物检测方法可以有效地检测无线充电系统的原副边之间是否有异物存在。
摘要（英）：

A foreign substance detection method comprises: detecting a current first switching frequency of a wireless charging system during the process of performing wireless charging by using a primary side and a secondary side of the wireless charging system (101); acquiring a second switching frequency of the wireless charging system when no foreign substance exists between the primary side and the secondary side of the wireless charging system (102); and when a difference between the first switching frequency and the second switching frequency is in a preset range, determining that a foreign substance exists between the primary side and the secondary side of the wireless charging system (103). The foreign substance detection method can effectively detect whether a foreign substance exists between the primary side and the secondary side of the wireless charging system.
