Example Embodiment

[0067] In order to better explain the present invention, the current charging technology is first introduced below.

[0068] Low-power wireless charging (receiving end power less than 5W) due to the slow charging rate and poor user experience, has gradually withdrawn from the market. The latest standard of the Wireless Charging Standard (QI) introduces medium-power wireless charging with a receiving end power greater than 5W and less than 15W, and this increase in power will be accompanied by serious heating problems in practical applications.

[0069] When researching 5 to 15W wireless charging products, it was found that the charging efficiency of the wireless charging terminal is higher only when the center point of the wireless charging plate is located, the charging efficiency is about 70%, the heat generation is relatively small, and the offset center point is large. In order to ensure that the input power of the receiving end remains unchanged, the transmitting end often tra...

Abstract

The embodiment of the invention discloses a charging control method and device and a mobile terminal. The charging control method comprises the steps of detecting a charging mode; judging whether an application runs in the system or not when it is detected that the charging mode is wireless charging; determining a wireless charging current value according to the judgment result; and wirelessly charging a battery of the mobile terminal according to the determined wireless charging current value.

Description

technical field [0001] The invention relates to the field of terminal product charging, in particular to a charging control method and device. Background technique [0002] At present, all mobile terminals with wireless charging have safety problems of wireless charging and fast charging. Due to structural problems, the wireless charging coils are all located above the cell position on the back of the battery of the mobile terminal. During wireless charging, the wireless charging coil behind the battery is seriously heated, and the heat is conducted to the battery. Due to the limited space, the heat cannot be dissipated for a long time, causing the battery to bulge and open the front panel. Therefore, the heating problem of wireless charging has become a major obstacle restricting the development of wireless charging, and how to solve the safety problem caused by wireless charging heating is an urgent problem to be solved. Contents of the invention [0003] In order to s...
