QUICK-CHARGING CONTROL METHOD AND SYSTEM

摘要

A quick-charging control method and system suitable for the field of mobile terminals. The method comprises: (S1) a first controller (11) obtaining a voltage value of a cell by means of a cell connector, and sending the obtained voltage value to a second controller (21); (S2) the second controller finding a current regulation instruction matching a threshold section that the voltage value falls within from a threshold section table, and sending a current regulation instruction to a regulation circuit (22); (S3) the regulation circuit regulating a current according the current regulation instruction, and outputting a power supply signal of which the current is regulated; (S4) when the second controller detects second exceptional charging information, the second controller separately sending a second shutoff instruction to the first controller and a second switch circuit (23); and (S5) when the second switch circuit receives the second shutoff instruction, the second switch circuit stopping a charging adapter (2) to output a power supply signal of which the current is regulated. In this manner, a charging current flowing into a cell can be regulated in real time, so that the overcharging of the cell is avoided; in addition, when a charging exception occurs, a charging adapter is stopped in time from charging a cell of a mobile terminal (1).
