Abstract

The invention provides a charging method and to-be-charged equipment. The method comprises the following steps: acquiring the charging duration of a battery in to-be-charged equipment in a predetermined charging stage in at least one previous charging process; comparing the charging duration with a preset duration threshold value; and determining whether to adjust the charging parameters of the battery in the constant-current charging stage or not based on the comparison result of the charging duration and the duration threshold so as to prolong the charging duration of the constant-current charging stage. According to the method, the problem that the charging speed is reduced when the battery is aged can be solved.

Description

technical field [0001] The present disclosure relates to the technical field of electronic devices, and in particular to a charging method and a device to be charged. Background technique [0002] Electronic devices (such as smart phones, tablet computers and other smart devices) are increasingly favored by consumers, but these electronic devices consume a lot of power and need to be recharged frequently. It usually takes several hours to charge these devices to be charged with a low-power common charging solution. In order to meet this challenge, on the basis of normal charging, the industry has successively proposed fast charging solutions. [0003] Fast charging of the battery, as the battery is repeatedly charged and discharged, it will gradually age, and its impedance will become larger and larger, causing the battery to quickly reach the cut-off voltage. As a result, the charging time becomes longer. [0004] It should be noted that the information disclosed in the a...
