Abstract
A quick-charging control method and system are suitable for mobile terminals. The method includes: a first controller obtaining a voltage value of a cell, and sending the voltage value to a second controller; the second controller searching a threshold segment table to find a current regulation instruction matched with a threshold segment containing the voltage value of the cell, and sending the current regulation instruction to a regulation circuit; the regulation circuit performing a current regulation according the current regulation instruction, and outputting a power signal; the second controller sending a second switch-off instruction to the first controller and a second switch circuit respectively if second abnormal charging information is detected; and the second switch circuit, controlling the charging adapter to stop sending the power signal after the current regulation if the second switch circuit receives the second switch-off instruction.
