Mobile terminal, direct charging power adapter and charging method

The invention discloses a mobile terminal, a direct charging power adapter and a charging method. The charging method comprises the steps that firstly, the direct charging power adapter is arranged and is in communication with the mobile terminal in a UART communication mode; secondly, according to the difference of the configuration conditions of communication pins of different charged devices, a charging type identification strategy is designed in the mobile terminal, and accordingly automatic identification of the mobile terminal on the types of external devices is achieved. Meanwhile, a special fast charging mode is designed for the direct charging power adapter; charging voltage output by the direct charging power adapter is used for conducting high-current direct charging on a battery during the period when centralized charging is conducted on the battery of the mobile terminal, and the volt value of the charging voltage is adjusted dynamically according to change of the voltage of the battery; thus, on the premise of ensuring battery charging safety, the charging speed of the battery is substantially increased, the time required for charging the mobile terminal every time is shortened, and the influence caused when the mobile terminal needs to be charged frequently for a long time on a user during daily use is reduced.
