Abstract

The invention provides a charging method, a mobile terminal and a charger. The charging method comprises the steps of performing constant current charging on a battery of the mobile terminal; when thevoltage value of the battery of the mobile terminal reaches a preset voltage threshold value, and when it is detected that the current value of a charging current output by the charger is not loweredfrom a first current value to a second current value, controlling a communication signal transmitted between the mobile terminal and the charger to be in a low-level state; and after the first presettime frame, controlling the communication signal transmitted between the mobile terminal and the charger to be in a high-level state, and transmitting a first current lowering instruction to the charger. Therefore, by controlling the communication signal transmitted between the mobile terminal and the charger to be in the low-level state for a certain while, the charger can perform a reset communication access operation to further respond the first current lowering instruction transmitted by the mobile terminal, thereby lowering the current value of the charging current output by the charger,and lowering risk of battery damage of the mobile terminal.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a charging method, a mobile terminal and a charger. Background technique [0002] Currently, when charging the battery of a mobile terminal, fast charging technology can be used. The control mode of the fast charging technology can be a voltage loop control mode and a current loop control mode. For the current loop control method, the charger can always output a fixed current, which is not affected by the output voltage of the charger. There are certain security risks in the current loop control mode. During the charging process, when the voltage of the battery of the mobile terminal reaches a certain value, the output current of the charger cannot be too large. If the charger breaks down at this time, the charger may still charge the battery of the mobile terminal with a large current, which will increase the temperature of the battery of the mobile terminal, and the ba...
