Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for controlling temperature rise during charging of a terminal device according to an embodiment of the present invention; it should be noted that the terminal device referred to in the present invention includes a mobile phone, a tablet computer, a notebook computer, and the like. The method includes, but is not limited to, the following steps.
Step S100, detecting whether the terminal device is in a charging state.
The specific method of this step may be to detect the operating state of the charging circuit, or to detect whether the charging prompt is turned on, or the like. Specific detection methods are within the understanding of those skilled in the art and are not listed here.
Step S110, if the terminal device is in a charging state, determining whether the electric quantity of the battery of the terminal device is smaller than a preset electric quantity value.
In this step, if the terminal device is in a non-charging state, all subsequent steps of the method are stopped. The preset value of the power may be a preset ratio of the total power of the battery, such as 30% of the total power. Of course, the value can be set by a person skilled in the art according to the total battery capacity and the endurance of the terminal device, and is not limited specifically here.
And step S120, if the electric quantity of the battery of the terminal equipment is smaller than the preset electric quantity value, detecting the temperature of the battery of the terminal equipment.
The method of measuring the temperature of the terminal device battery may include by providing a sensor or thermistor or the like on or near the battery.
For example, a Negative temperature coefficient thermistor (NTC) is provided, and is connected to a battery of a terminal device, because the resistance of the NTC is inversely proportional to the temperature, the resistance decreases with a high temperature and increases with a low temperature, and the temperature coefficient is very large, so that the NTC can be used for detecting a small temperature change, and the accuracy is high. According to the characteristics of the NTC resistor, the NTC can generate different voltages of the NTC resistor in different temperature environments; the current temperature value of the battery is determined by monitoring the voltage value of the negative temperature coefficient thermistor.
Step S130, when the temperature of the battery of the terminal equipment is in a first temperature threshold interval, charging the terminal equipment in a constant voltage mode; and when the temperature of the battery of the terminal equipment is in the second temperature threshold interval, charging the terminal equipment in a first constant current mode.
In this step, preferably, the temperature value of the first temperature threshold interval is smaller than the temperature value of the second temperature threshold interval; for example, the first temperature threshold range may be 30-60 degrees celsius and the second temperature threshold range may be 60-80 degrees celsius.
Generally, the charging current in the constant-voltage charging is larger than the charging current in the constant-current charging, and when the battery temperature is low, the charging can be performed in the constant-voltage charging with a large current, and when the battery temperature is low, the charging can be performed in the first constant-current charging with a small current.
Compared with the prior art, the temperature rise control method for the terminal equipment during charging provided by the embodiment of the invention detects the temperature of the battery of the terminal equipment under the condition that the electric quantity of the battery of the terminal equipment in the charging state is detected to be smaller than the preset electric quantity value, and determines the adopted charging strategy (charging the terminal equipment in a constant current mode or charging in a constant voltage mode) according to different temperature threshold value intervals of the temperature of the battery, so that the temperature rise control during charging of the terminal equipment is realized, and the overhigh temperature rise of the terminal equipment is avoided.

Also, the method of measuring the temperature of the battery of the terminal device may include by providing a sensor or thermistor or the like on or near the battery.
Step S203, judging the temperature threshold interval where the temperature of the terminal equipment battery is located.
In this step, the temperature threshold interval is divided into two, namely a first temperature threshold interval and a second temperature threshold interval, and preferably, the temperature value of the first temperature threshold interval is smaller than that of the second temperature threshold interval; for example, the first temperature threshold range may be 30-60 degrees celsius and the second temperature threshold range may be 60-80 degrees celsius.
