Title:
CHARGING DEVICE, ELECTRIC QUANTITY CORRECTION METHOD OF WIRELESS EARPHONES, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/052245
Kind Code:
A1
Abstract:
Disclosed in some embodiments of the present application is an electric quantity correction method of wireless earphones. The wireless earphones comprise a voltameter; the voltameter determines the electric quantity of the wireless earphones according to a power supply voltage of the wireless earphones. The electric quantity correction method of the wireless earphones comprises the following steps: when a charging device is started for the first time after firmware upgrade is completed, obtaining an interval duration between a starting time point of the charging device and a predicted starting time point of the wireless earphones; determining a target duration according to the interval duration, the target duration being greater than or equal to the interval duration; and controlling a charging circuit in the charging device to break the target duration so as to enable the wireless earphones to perform discharge within the target duration. Also disclosed in the present application are a charging device and a readable storage medium. The wireless earphones in the present application have high electric quantity measurement accuracy after being upgraded.
