摘要： A charging control apparatus and method for an electronic device. In the process of charging a battery by the charging control apparatus for the electronic device, first, a power adapter charges the battery with a constant-voltage output direct current; after receiving a fast charge command sent by a charging control module, the power adapter adjusts the output voltage according to a battery voltage fed back by the charging control module; when the output voltage meets a fast charge voltage condition preset by the charging control module, the power adapter adjusts the output current and the output voltage according to a fast charge current value and a fast charge voltage value so as to perform fast charge on the battery; and during the fast charge, the power adapter further adjusts the output current in real time according to its output voltage and the battery voltage, so that fast charge of the battery is accomplished by adjusting the output current and the output voltage of the power adapter.
