Title:
CHARGING MANAGEMENT CIRCUIT, TERMINAL AND CHARGING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/051790
Kind Code:
A1
Abstract:
Provided are a charging management circuit, a terminal and a charging method. The charging management circuit comprises: a first output end, which is used for carrying out constant current charging on a cell; a second output end, which is used for supplying power to a load during the constant current charging process; and a control circuit, which is used for stopping constant current charging when the voltage at two ends of the cell reaches a constant current charging cut-off voltage for constant current charging, wherein the constant current charging cut-off voltage is greater than the rated voltage of the cell, and the configuration of the constant current charging cut-off voltage enables the real voltage of the cell to go over voltage during the constant current charging process. The charging management circuit is used to carry out constant current charging, and the constant current charging cut-off voltage is configured to be greater than the rated voltage of a cell such that the charging speed of the cell may be improved.
