Embodiment 1

[0057] Such as figure 1 As shown, a charging method is disclosed in this embodiment, and the method includes:

[0058] S101. The mobile terminal detects that there is current input;

[0059] S102. The mobile terminal sends a communication signal to the charger;

[0060] S103. If the communication between the mobile terminal and the charger is successfully established, the mobile terminal collects battery parameters;

[0061] S104. The mobile terminal determines corresponding charging parameters according to the collected battery parameters;

[0062] S105. The mobile terminal sends the charging parameters to the charger.

[0063] Compared with the prior art, this embodiment has the following beneficial effects: in the prior art, if ordinary charging is used, it will be relatively slow; if fast charging is adopted, it is generally charged with high voltage and high current. This charging method has relatively high requirements on the impedance of data lines and interface par...

Abstract

The invention discloses a charging method. The method comprises the following steps: detecting current input by a mobile terminal; sending out a communication signal to a charger by the mobile terminal; if communication established between the mobile terminal and the charger is successful, collecting battery parameters by the mobile terminal; determining corresponding charging parameters according to the collected battery parameters by the mobile terminal; and sending the charging parameters to the charger by the mobile terminal. The charger can charge a battery according to the charging parameters determined in the mobile terminal; when the temperature of the battery is relatively low and lower than a threshold value and the potential safety hazard is relatively low, quick charging can be carried out by using high voltage and high current, so that the charging efficiency is quickened; and when the temperature of the battery is relatively high or when the battery is ready to be full, charging can be carried out by using safer voltage and current, so that the heating of the battery is reduced, and the safety of the battery is improved. The invention also discloses a charging device and a charger.

Description

technical field [0001] The present invention relates to the technical field of charging, and more specifically, to a charging method, device and charger. Background technique [0002] In modern society, mobile terminals such as mobile phones and tablets have almost become necessities in everyone's life, and various mobile terminals are continuously enriched and convenient for the public. Due to the advantages of convenience, quickness, resource saving, and other advantages of using a mobile terminal to process information, the mobile terminal becomes an indispensable part of a user's life or work. [0003] The battery of a mobile terminal will generally be in a power-short state after being used for one day, and people are often eager to deal with some events and need to charge the mobile terminal quickly. -4.5A charging scheme, or use charging IC to realize 9V or 12V, 1.5-2A charging. However, these solutions have relatively high requirements on the high impedance of data...
