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 present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] Please refer to figure 1 , is a schematic flow chart of the first embodiment of the charging method of the present invention, 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 analog-to-digital conversion ADC (Analog-to-Digital Convert) detection circuit or a charging integrated circuit IC (Integrated Circuit).

[0020] In this embodiment, the detection process of the fast chargi...

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 invention relates to the field of electronic technology, in particular to a charging method for a mobile terminal and the mobile terminal. Background technique [0002] As the battery capacity of the mobile terminal increases, the corresponding battery charging time also becomes longer and longer. The birth of the fast charging communication protocol effectively shortens the charging time of the battery and provides convenience for users' daily life. At the same time, with the mutual compatibility of multiple fast charging and 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 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,...
