Title:
CHARGING CONTROL METHOD AND APPARATUS, TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/103932
Kind Code:
A1
Abstract:
Disclosed in the present application are a charging control method and apparatus, a terminal device, and a storage medium. The method comprises: detecting direct current impedance of a battery; setting a charging cut-off voltage of a constant-current charging stage during current charging according to the detected direct current impedance of the battery and a charging cut-off current; and charging the battery according to the set charging cut-off voltage. According to the present application, a charging parameter is adjusted in real time by tracking an impedance change of a battery, and a charging cut-off voltage and impedance are considered in connection. When the impedance increases, the charging cut-off voltage is correspondingly increased, and thus the problem of the charging time of a battery being longer and longer with the aggravation of aging is solved.
