Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, the present invention provides some embodiments of a mobile terminal charging control method.
As shown in fig. 1, the charging control method for a mobile terminal of the present invention includes the following steps:
step S100, setting a charging circuit of the mobile terminal as a plurality of charging branches.
The step S100 specifically includes:
step S110, setting a charging circuit of the mobile terminal as a plurality of charging branches.
Specifically, in the prior art, a fixed charging circuit is used for charging the mobile terminal. The invention classifies the circuits available for charging of the mobile terminal as charging circuits, and then sets the circuits into a plurality of charging branches. The plurality of charging branches are connected in parallel, and of course, elements with larger resistance (i.e. elements with more heat generation) can be connected in parallel, and elements with smaller resistance (i.e. elements with less heat generation) can be connected in series.
And step S120, respectively starting each charging branch, detecting the temperature rising rate and the highest temperature value of the mobile terminal in preset time, and forming a charging branch and temperature rising rate correspondence table and the temperature distribution of the mobile terminal.
After each charging branch is set, each charging branch is sequentially started, the temperature value of the mobile terminal in the preset time is detected, and the heating rate of the mobile terminal in the preset time is calculated, wherein the heating rate can be an average heating rate or a heating curve. Therefore, a corresponding table of the charging branches and the temperature rising rate can be obtained, and the speed of temperature rising caused by charging when each charging branch is started is also known. The temperature rising curve is usually increased, that is, when the preset time is reached, the temperature of the mobile terminal is the highest temperature value, and of course, the highest temperature value corresponding to each charging branch is different, the temperature influence of each charging branch on different areas of the mobile terminal is also different, the temperature distribution of the mobile terminal can be obtained through the highest temperature value and the temperature value of each area of the mobile terminal, and of course, different charging branches are started, and the temperature distribution of the mobile terminal is different.
And step 200, when detecting that the mobile terminal is connected with the battery for charging, starting a charging branch circuit to charge the battery, closing the rest charging branch circuits and resetting a timer.
Specifically, when it is detected that the mobile terminal is connected to the power supply to charge, any charging branch is opened to charge, and it is of course also possible to set that a default charging branch is opened, that is, the default charging branch is opened first. Of course, in the invention, a charging branch is opened in an alternative mode, one of the charging branches is opened, and the rest charging branches are in a closed state. Of course, when more (for example, more than three) charging branches are provided, if rapid charging is required, a plurality of charging branches can be opened through setting. When a certain charging branch is started, the timer is reset, namely, the timer is cleared, so that the later timing is facilitated.
And step S300, detecting the temperature of the mobile terminal, and switching the charging branch and resetting the timer when the temperature exceeds a set threshold and the timer is overtime.
Specifically, step S300 specifically includes:
and step S310, detecting the temperature of the mobile terminal, and switching the charging branch according to the charging branch and heating rate corresponding table and the temperature distribution of the mobile terminal when the temperature exceeds a set threshold and the timer is overtime.
Detecting the temperature of the mobile terminal, and starting a timer when the temperature exceeds a set threshold. Of course, the timer may be reset later when the temperature is below the set threshold due to temperature fluctuations. And switching the charging branch circuit only when the temperature continuously exceeds a set threshold and reaches the time of overtime of the timer, namely selecting one charging branch circuit from the rest charging branch circuits to be started, and closing the current charging branch circuit. When one charging branch is selected from the rest charging branches to be started, the charging branches are selected according to a charging branch and heating rate correspondence table and the temperature distribution of the mobile terminal, for example, the charging branch with low heating rate is selected preferentially, and then the charging branch with high heating rate is selected. The charging branch circuit far away from the processor is preferably selected, so that the processor is prevented from being overheated and causing dead halt. The charging branch far away from the current charging branch is used as the charging branch to be switched, so that the damage of elements caused by overhigh temperature in the same area can be avoided.
Step S320, resetting the timer.
The timer is reset after switching the charging branch.
Further, the set threshold is 50 ℃, and the time out of the timer is 30 seconds. Of course, the set threshold and the time of the timer timeout can be set according to the needs, for example, the user can set the timer.
Of course, when all the charging branches do not meet the requirements (i.e. the temperature exceeds the set threshold and the timer is overtime), in order to avoid frequent switching between the charging branches, the charging of the mobile terminal is stopped, and the charging is continued after the temperature drops to the preset temperature value.
It is worth to say that the branch circuit through which a plurality of charging currents flow is added on the mobile terminal, so that the problem of heat accumulation caused by long-time charging on the same charging branch circuit is reduced, the safety of the charging process is ensured, meanwhile, the temperature of the mobile terminal in the charging process is also reduced, and the service life of the mobile terminal is prolonged.
