CHARGING CONTROL METHOD AND DEVICE POWER ADAPTER AND MOBILE TERMINAL

摘要

Provided are a charging control method and device a power adapter and a mobile terminal. The method is applicable to a power adapter. When the power adapter is connected to a mobile terminal a charging circuit is formed between the power adapter and the mobile terminal for transmitting a direct current. The method comprises: the power adapter provides a direct current voltage on the basis of an alternating current voltage obtained from an external power supply; when the power adapter is connected to a first mobile terminal the power adapter transmits a direct current generated on the basis of the direct current voltage to the first mobile terminal by means of a first charging circuit formed between the power adapter and the first mobile terminal; when determining that an exception occurs to the first charging circuit the power adapter forbids supply of the direct current voltage; the power adapter determines the connection state between the power adapter and the first mobile terminal and when the connection state is that the power adapter and the first mobile terminal are disconnected the power adapter allows the supply of the direct current voltage so that the safety of charging is improved.
