Problems solved by technology

[0003] In view of the above terminal heating problem, at present, the temperature of the battery is mainly detected, and the charging current of the battery is adjusted accordingly according to the current temperature of the battery, so as to reduce the heat loss generated by the terminal; however, because the charging current of the battery itself is less than The input current of the charging integrated circuit (Integrated Circuit, IC) has a limited range of reducing the battery charging current, so the control effect on terminal heating is not obvious

Embodiment 1

[0044] see figure 1 , which shows a flow of a method for controlling terminal temperature provided by an embodiment of the present invention, the method may include:

[0045] S110. The terminal acquires temperature information of at least one heat source of itself;

[0046] It should be noted that the heat source refers to a hardware unit that generates heat loss during operation of the terminal, and may mainly include but not limited to: a battery, a CPU, and a power amplifier. This embodiment of the present invention does not describe it in detail.

[0047] Exemplarily, the terminal obtains temperature information of at least one heat source of itself; the temperature information includes the temperature of the battery in the heat source and terminal temperature information; wherein, the method for obtaining the terminal temperature information may specifically include: the terminal detects the temperature of each heat source temperature, and acquire the terminal temperatu...

Embodiment 2

[0077] Based on the same technical concept as the foregoing embodiments, this embodiment describes the technical solutions of the foregoing embodiments through specific examples.

[0078] Take a certain Ti BQ series charging IC with dynamic path management as an example. The charging IC and the baseband processor are controlled by an I2C serial bus. The baseband processor can change the charging status and input current of the charging IC in real time through the I2C bus. size. The input voltage of the terminal charging IC is constant at 5V, the default maximum input current is 1000mA, and the thermal efficiency of the charging IC is 15%. The system load composed of the baseband circuit and the radio frequency circuit converts to a maximum operating current of 800mA at the input end, and the safe charging temperature of the battery used is 45°C.

[0079] When the system load is in the extreme working state, the battery charging current converted to the input terminal is 200mA...

Embodiment 3

[0087] Based on the same technical idea of ​​the foregoing embodiments, see Figure 5 , which shows a terminal 50 provided by an embodiment of the present invention, the terminal 50 may include: a temperature information acquisition module 510, a control signal generation module 520, a charging IC control module 530, and a charging IC 540; wherein,

[0088] The temperature information acquisition module 510 is configured to acquire temperature information of at least one heat source of the terminal itself;

[0089] The control signal generation module 520 is configured to determine the temperature range where the temperature information is currently located, and generate a corresponding control signal;

[0090] The charging IC control module 530 is configured to control the working state of the charging IC 540 according to the control signal.

Abstract

The embodiment of the present invention discloses a terminal and a method for controlling the temperature of the terminal. The method includes: obtaining temperature information of at least one heat source of the terminal itself; determining the temperature range where the temperature information is currently located, and generating a corresponding control signal; The control signal controls the working state of the charging integrated circuit IC.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a terminal and a method for controlling the temperature of the terminal. Background technique [0002] With the increasing convenience and intelligence of terminals, terminal application functions are becoming more and more abundant, which brings convenience to users and also brings the problem of terminal heating. If the heating problem cannot be well controlled, it will not only bring thermal experience complaints to users, but even cause safety accidents in some extreme cases. When the terminal is charging, the system load is still in the working state. At this time, the terminal generates the most heat. Therefore, how to reduce thermal power consumption under such conditions to achieve the purpose of reducing heat generation is particularly critical. [0003] In view of the above terminal heating problem, at present, the temperature of the battery is mainly detected, and t...
