Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, or apparatus.

For convenience of description, the above-mentioned devices are collectively referred to as terminal devices. Embodiments of the present invention will be described below with reference to the accompanying drawings.
The embodiment of the invention provides a method for detecting charging heating abnormity and terminal equipment, which can monitor whether the terminal equipment is abnormal in charging heating or not in real time. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for detecting charging heating abnormality according to an embodiment of the present invention. The method for detecting the charging heat generation abnormality shown in fig. 1 may include the following steps:
101. acquiring a first voltage U of a Universal Serial Bus (USB) port of a terminal device which is being charged1And a first current I1。
In the embodiment of the invention, the terminal equipment can be provided with the ammeter at the USB port, so that the first voltage U of the USB port can be acquired in real time1And a first current I1。
102. Obtaining a second voltage U of the terminal device battery2And a second current I flowing into the battery2。
In the embodiment of the invention, the terminal equipment can also be provided with the electricity meter at the electrode of the battery, so that the second voltage U of the battery can be acquired in real time2And a second current I flowing into the battery2。
103. According to U1、I1、U2And I2A target charging efficiency is calculated.
As an optional implementation manner, after acquiring U1、I1、U2And I2Then, the target charging efficiency may be calculated by the following calculation formula:
where X is the target charging efficiency.
In the above embodiment, by calculating the ratio between the power at the battery and the input power at the USB during charging, the target charging efficiency can be obtained, so that the power loss during charging can be known. Analyzing the target charging efficiency to know that the larger the target charging efficiency is, the lower the power lost in the charging process is, and the lower the heat generation of the terminal equipment is; conversely, if the target charging efficiency is smaller, the higher the power lost in the charging stroke, the higher the heat generation of the terminal device. Therefore, by monitoring the target charging efficiency, it is possible to monitor whether or not the terminal device is abnormally charged and generates heat.
Further, in the charging process, factors such as the ambient temperature, the usage condition of the terminal device, and the device aging condition of the terminal device all affect the charging efficiency. In order to make the calculated target charging efficiency reflect the charging heat loss of the terminal device more accurately, a certain correction coefficient may be included in the calculation method of the target charging efficiency.
For example, if only the influence of the ambient temperature is considered, the charging efficiency is higher when the ambient temperature is higher in the normal operating temperature range of the terminal device (e.g., 10 ℃ below zero to 40 ℃ above zero), and if the ambient temperature introduced parameter is α (α is greater than 1), the target charging efficiency calculation formula after correction is:
104. and determining whether the terminal equipment is abnormal in charging and heating according to the target charging efficiency.
As an optional implementation manner, the terminal device may obtain a current electric quantity value of the battery, then query a standard charging efficiency corresponding to the electric quantity value, then compare the target charging efficiency with the standard charging efficiency, and if the target charging efficiency is significantly lower than the standard charging efficiency, determine that the terminal device generates heat abnormally during charging. The standard charging efficiency may be a charging efficiency measured in advance at the electric quantity value when the terminal device has no abnormal heat generation.
As another optional implementation, the terminal device may obtain a current electric quantity value of the battery, calculate a target proportional relationship between the target charging efficiency and the electric quantity value, compare the target proportional relationship with a preset proportional relationship when the electric quantity value is obtained to obtain a difference value, and determine that the terminal device generates heat when charging if the difference value is greater than a first preset threshold value.

Referring to fig. 2, fig. 2 is a line graph illustrating the battery capacity and the charging efficiency according to an embodiment of the present invention. In fig. 2, a broken line represented by a square is a schematic diagram of a relationship between battery power and charging efficiency obtained when the terminal device is not abnormal in charging and heating; and a broken line represented by a diamond is a schematic diagram of the relationship between the battery capacity and the charging efficiency obtained by the monitoring terminal equipment at this time. Wherein the horizontal axis represents the percentage of battery charge and the vertical axis represents the charge efficiency. For example, if the current battery level of the terminal device is 60%, the difference between the corresponding charging efficiency and the charging efficiency X1 and the charging efficiency X2 when the terminal device is not charged and generates heat abnormally is δ, and if δ is greater than 0.1, it is determined that the terminal device is charged and generates heat abnormally.
Besides, the embodiment of the invention can also determine whether the terminal equipment is abnormal in charging and heating by the following method:
according to U2And I2Calculating a target resistance value of the battery, then acquiring the current electric quantity value of the battery, and then acquiring a standard resistance value corresponding to the electric quantity value; and comparing the target resistance value with the standard resistance value, and if the difference value of the target resistance value and the standard resistance value is larger than a second preset threshold value, determining that the terminal equipment is abnormal in charging and heating.
In the above embodiment, if the resistance value of the battery is increased (i.e. the target resistance value is greater than the standard resistance value), more power is lost and converted into heat energy, which causes abnormal heat generation during charging of the terminal device.
It can be seen that with the method described in fig. 1, the power loss of the terminal device during charging can be monitored based on the power input to the terminal device by the USB and the charging power at the battery; since the power loss is mainly converted into heat energy, whether the terminal equipment is charged or not and generates heat abnormally can be monitored in real time by monitoring the power loss.

302. Obtaining a second voltage U of the terminal device battery2And a second current I flowing into the battery2。
In the embodiment of the invention, the terminal equipment can also be provided with the electricity meter at the electrode of the battery, so that the second voltage U of the battery can be acquired in real time2And a second current I flowing into the battery2。
303. According to U1、I1、U2And I2A target charging efficiency is calculated.
As an optional implementation manner, after acquiring U1、I1、U2And I2Then, the target charging efficiency may be calculated by the following calculation formula:
where X is the target charging efficiency.
In the above embodiment, by calculating the ratio between the power at the battery and the input power at the USB during charging, the target charging efficiency can be obtained, so that the power loss during charging can be known. Analyzing the target charging efficiency to know that the larger the target charging efficiency is, the lower the power lost in the charging process is, and the lower the heat generation of the terminal equipment is; conversely, if the target charging efficiency is smaller, the higher the power lost in the charging stroke, the higher the heat generation of the terminal device. Therefore, by monitoring the target charging efficiency, it is possible to monitor whether or not the terminal device is abnormally charged and generates heat.
304. And determining whether the terminal equipment is abnormal in charging and heating according to the target charging efficiency.
As an optional implementation manner, the terminal device may obtain a current electric quantity value of the battery, then query a standard charging efficiency corresponding to the electric quantity value, then compare the target charging efficiency with the standard charging efficiency, and if the target charging efficiency is significantly lower than the standard charging efficiency, determine that the terminal device generates heat abnormally during charging. The standard charging efficiency may be a charging efficiency measured in advance at the electric quantity value when the terminal device has no abnormal heat generation.
305. And acquiring the running process in the terminal equipment under the condition that the charging and heating of the terminal equipment are abnormal.
In the embodiment of the invention, if the terminal equipment generates heat during charging, the heating condition of the terminal equipment can be prevented from further worsening by considering ways of reducing the running process in the terminal equipment, reducing the running power consumption of a processor and the like.
306. And determining the priority of the process, if the priority of the process is low, ending the process, and if the priority of the process is high, reducing the frequency of a processor of the terminal equipment to run the process.
As another optional implementation, the terminal device may further output a prompt message to prompt the user to stop charging or stop using the terminal device during charging when the charging is abnormal in heating, so as to alleviate the heating of the terminal device, prolong the service life of the terminal device, and avoid dangerous accidents such as battery explosion.
It can be seen that with the method described in fig. 3, the power loss of the terminal device during charging can be monitored based on the power input to the terminal device by the USB and the charging power at the battery; since the power loss is mainly converted into heat energy, whether the terminal equipment is charged or not and generates heat abnormally can be monitored in real time by monitoring the power loss.

Wherein the horizontal axis represents the percentage of battery charge and the vertical axis represents the charge efficiency. For example, if the current battery level of the terminal device is 60%, the difference between the corresponding charging efficiency and the charging efficiency X1 and the charging efficiency X2 when the terminal device is not charged and generates heat abnormally is δ, and if δ is greater than 0.1, it is determined that the terminal device is charged and generates heat abnormally.
