Abstract
A charging control apparatus and method for an electronic device are provided. During a process of charging, the power adapter first charges the battery with a constant-voltage direct current output, and then after the power adapter receives a quick-charging instruction, the power adapter adjusts an output voltage according to the voltage of the battery fed back by the charging control circuit, and if the output voltage meets a quick-charging voltage condition pre-set by the charging control circuit, the power adapter adjusts an output current and the output voltage respectively according to a preset quick-charging current value and a preset quick-charging voltage value for quick-charging the battery, and meanwhile the charging control circuit introduces direct current from the power adapter for charging the battery; during a process of quick-charging, the power adapter adjusts the output current in real time according to the output voltage thereof and the voltage of the battery.
