In a practical application scenario, taking three heat sources of a battery, a CPU, and a power amplifier as an example, the terminal can detect and acquire the temperatures of the heat sources by setting temperature detectors near the three heat sources, and the temperatures of the heat sources. A weighted average calculation is performed to obtain terminal temperature information capable of characterizing the temperature of the terminal.

Understandably, in the process of performing weighted average calculation, the weight of each heat source temperature may be In order to set according to its own thermal efficiency, optionally, the weights of the respective heat sources may be set to be the same, so that the terminal temperature information can be obtained only by calculating the average value of the respective heat source temperatures.

It should be noted that the charging IC of the terminal has a dynamic path management function, and the working principle of the terminal charging IC is as shown in FIG. 2, as can be seen from the figure, the charging IC of the terminal is dynamically managed according to its own. the input current I _in policy decomposed into two currents, one current I _battery for battery charging, the way a system for load current I _system; wherein, the system load may be composed of a CPU and a power amplifier. Understandably, when battery charging is disabled, the input current to the charging IC is all used to power the system load.

S130. The terminal controls an operating state of the charging integrated circuit IC according to the control signal.

The solution shown in FIG. 1 obtains temperature information of at least one heat source by the terminal, determines a temperature interval in which the temperature information is currently located, and generates a corresponding control signal, thereby implementing adjustment of the working state of the charging IC by using the control signal, This reduces the heat loss of the input current on the charging IC and reduces the temperature of the terminal.

Illustratively, the determining, by the terminal, the temperature interval in which the temperature information is currently located, and generating a corresponding control signal may include:

The terminal generates a first control signal when the battery temperature is lower than a preset first temperature threshold; wherein the first control signal is used to indicate that the terminal normally charges the battery, and inputs the charging IC into the current Set to maximum;

Or, when the battery temperature is higher than a preset first temperature threshold, and the terminal temperature information is less than a preset second temperature threshold, the terminal generates a second control signal; wherein the second control signal is used Instructing the terminal to disable charging of the battery and setting the charging IC input current to a maximum;

Or, when the battery temperature is higher than a preset first temperature threshold, and the terminal temperature information is greater than a preset second temperature threshold and less than a preset third temperature threshold, the terminal generates a third a control signal, wherein the third control signal is used to instruct the terminal to disable charging of the battery, and set the charging IC input current to be less than a value of the maximum input current;

Embodiment 2

Based on the same technical concept of the foregoing embodiment, the present embodiment describes the technical solution of the foregoing embodiment by an optional example.

Taking a BQ series charging IC with dynamic path management as an example, the I2C serial bus control is adopted between the charging IC and the baseband processor. The baseband processor can change the charging state and input current of the charging IC in real time through the I2C bus. size. The terminal charging IC input voltage is constant at 5V, the default maximum input current is 1000mA, and the charging IC thermal efficiency is 15%. The system load composed of the baseband circuit and the RF circuit is converted to a maximum operating current of 800 mA at the input end, and the battery safe charging temperature is 45 °C.

When the system load is in the limit working state, the battery charging current converted to the input terminal is 200mA. When the battery temperature is less than 45 ° C, the heat loss calculation formula (1) shows that the heat loss generated by the terminal charging IC is the largest, which is 750 mW. When the detection temperature exceeds 45 °C, the baseband processor sends a prohibition charging command to the BQ charging chip through I2C. At this time, the heat loss of the charging IC is reduced, and the reduced heat loss is 150 mW, that is, from 750 mW to 500 mW, therefore, the terminal is The rise in temperature has a certain inhibitory effect; however, due to insufficient reduction, the effect is not significant and the terminal temperature may not reach equilibrium.

P _w =V _in *I _in *η

(1)

Among them, the heat loss is the input voltage and the input current is the thermal efficiency.

When the average temperature continues to rise above the preset second temperature threshold by several heat source temperature sampling, the baseband processor adjusts the input current of the BQ charger to half of the maximum value, ie, 500 mA, through I2C, at which time the heat loss is from The previous 500mW was reduced to 375mW, so the upward trend of the terminal was further suppressed.

If the temperature continues to rise beyond the preset third temperature threshold, the baseband processor sets the input current 0 of the BQ charger through I2C. At this time, the heat loss of the charging IC changes from the initial 750mW to 0mW, so the temperature rise of the terminal. Will get a greater inhibition, and even eventually reach equilibrium.

In the case of changing the input current, if the system load is still in the limit working state, there may be a power requirement that the input current cannot meet the normal operation of the terminal, and at this time, the battery will replenish the terminal, in order to prevent the battery from being insufficient. When the terminal is turned off, the software will monitor the battery power in real time. Once it reaches a warning value, it will re-adjust the input current to the maximum state. However, in order to control the terminal temperature, the software also needs to call the platform preset. A temperature control algorithm that reduces system load.

This embodiment provides an optional example to explain the foregoing technical solution. It can be known from the above description that the terminal controls the input by adjusting the input current of the charging IC according to the difference of the temperature of the whole machine. The heat loss generated by the power on the charging IC can achieve the purpose of lowering the temperature of the terminal.
