Title: (EN) Method for detecting foreign objects in an induction charging device
(ZH) 用于在感应充电装置中进行异物识别的方法
Abstract: front page image
(EN) A method for detecting foreign objects in an induction charging device 10, with the aid of at least one control and/or regulating unit 12 of the induction charging device 10, includes: ascertaining a resonance frequency f; determining an actual quality Qi at the resonance frequency f; and comparing the actual quality Qi to a setpoint quality Qs which is a function of a resonance frequency f.
(ZH) 本发明建议一种用于异物识别的方法,该方法用于在感应充电装置(10)、特别是手工工具蓄电池感应充电装置中借助于所述感应充电装置(10)的至少一个控制和/或调节单元(12)进行异物识别,其中,在第一方法步骤(14)中求得谐振频率(f),在第二方法步骤(16)中确定在所述谐振频率(f)情况下的实际品质(Qi),并且在第三方法步骤(18)中将所述实际品质(Qi)和取决于谐振频率(f)的额定品质(Qs)作比较。
