Problems solved by technology

[0003] However, the output voltage and current specifications of the fast charging chargers on the market are different, and the mobile terminal cannot effectively detect the output current of the fast charging charger, which makes the charging process have hidden dangers.
Taking a 5V, 2A charger as an example, the charging current of the charging IC can only be 2A at most, and the power of the charger cannot be maximized, resulting in a long charging time

Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0017] Please refer to figure 1 , Is a schematic flowchart of the first embodiment of the charging method of the present invention, and the charging method includes:

[0018] Step S11, detecting the voltage value of the output terminal of the charger.

[0019] In this embodiment, the mobile terminal can obtain the output terminal voltage value of the charger through an ADC (Analog-to-Digital Convert) detection circuit or a charging integrated circuit (IC).

[0020] In this embodiment, the detection process of the fast charge communication protocol can be completed before ste...

Abstract

The invention relates to the technical field of electrons, and provides a charging method for the mobile terminal. The method comprises the steps as follows: an output end voltage value of a charger is detected; a charge integrated circuit (IC) of the mobile terminal obtains power of the charger according to the output end voltage value of the charger; and charge current is configured according to the obtained power of the charger, so that the charge (IC) charges a battery according to the charge current. Accordingly, the invention further provides the mobile terminal. The charging speed can be improved; and the power of the charger is reasonably utilized.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a charging method of a mobile terminal and a mobile terminal. Background technique [0002] As the battery capacity of the mobile terminal increases, the corresponding battery charging time becomes longer and longer. The birth of the fast charging communication protocol effectively shortens the charging time of the battery and provides convenience to the user's daily life. At the same time, with the compatibility of multiple fast charging communication protocols, consumers can use different fast charging chargers to charge mobile terminals. [0003] However, the output voltage and current specifications of the fast-charging chargers currently on the market are different, and the mobile terminal cannot effectively detect the output current of the fast-charging charger, which makes the charging process risk hidden. Taking a 5V, 2A charger as an example, the charging current ...
