A charging control method, wherein the method is applied to a power adapter, wherein the power adapter is connectable with a mobile terminal to form a charging circuit for transmitting direct current, DC, current between the power adapter and the mobile terminal, and the method comprises: supplying a DC voltage based on an alternating current, AC, voltage obtained from an external power supply by the power adapter; when the power adapter is connected with the mobile terminal, transmitting a DC current formed based on the DC voltage to the mobile terminal through a first charging circuit formed between the power adapter and the mobile terminal by the power adapter; disabling the supply of the DC voltage by the power adapter upon determining that the first charging circuit is abnormal; and determining the connection between the power adapter and the mobile terminal, and enabling the supply of the DC voltage if the connection between the power adapter and the mobile terminal is disconnected and then re-established, by the power adapter, wherein a communication circuit for transmitting signals is formed between the power adapter and the mobile terminal when the power adapter is connected with the mobile terminal, the communication circuit being different from the charging circuit; and the process of determining the connection between the power adapter and the mobile terminal by the power adapter comprises: detecting, by the power adapter, the transmission of an abnormal indication signal transmitted from the mobile terminal through the communication circuit, wherein the abnormal indication signal is sent by the mobile terminal to the power adapter at a preset cycle during a period from the mobile terminal detects that the first charging circuit is abnormal until the mobile terminal detects that the connection between the mobile terminal and the power supply is disconnected, wherein the abnormal indication signal is communicated over the connection that is present between the power adapter and the mobile terminal; and detecting the reception of the abnormal indication signal after the abnormal indication signal is received by the power adapter, and determining that the connection between the power adapter and the mobile terminal is disconnected if the power adapter detects that the abnormal indication signal is not received within a preset time, wherein the preset time is greater than the preset cycle. supplying a DC voltage based on an alternating current, AC, voltage obtained from an external power supply by the power adapter;
