Detailed ways

The technical solution of the present application will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processing, many of the steps may be performed in parallel, concurrently, or simultaneously. Additionally, the order of steps may be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Fig. 1 is a schematic flowchart of a method for detecting abnormal charging provided by an embodiment of the present application. The method can be executed by a device for detecting abnormal charging, wherein the device can be implemented by software and/or hardware, and can generally be integrated in a mobile terminal. As shown in Figure 1, the method includes:

Step 101. When the mobile terminal is in the charging state, it is detected that a charging abnormality detection event is triggered.

Exemplarily, the mobile terminal in the embodiment of the present application may include a mobile device with a built-in battery, such as a mobile phone, a tablet computer, and a media player.

At present, mobile terminals generally support multiple charging methods, including a wired charging method and a wireless charging method. Among them, the wired charging method is generally realized through a Universal Serial Bus (USB) interface, and one end of the USB connection line is connected to the USB interface on the mobile terminal. Depending on the energy supply device connected to the other end of the USB connection line, it can also It is divided into power adapter charging method, mobile power charging method and USB charging method (the other end is generally connected to a computer) and so on. The solutions provided in the embodiments of the present application may be applicable to any charging method, which is not limited thereto. The charging state may mean that the mobile terminal has just entered the charging state, or may have been in the charging state for a period of time, which is not limited in this application. Generally, when the mobile terminal just enters the charging state, such as when the charger is plugged in, it provides voltage to the power management module, and the power management module will generate a charging interrupt signal to the processor. processor (Application Processor, AP), so as to know that the mobile terminal enters the charging state.

Exemplarily, the abnormal charging detection event can be automatically triggered when the mobile terminal just enters the charging state; Set the charging time, such as 30 minutes; the abnormal charging detection event can also be triggered by the user, such as the user is going to leave the mobile terminal to do something, such as cooking, can actively trigger the abnormal charging detection by turning on the abnormal charging detection event switch, etc. event. Of course, there may be many ways to trigger the abnormal charging detection event, which are not limited in this embodiment of the present application.

Step 102, acquiring the charging current value charged into the battery of the mobile terminal.

Generally, different energy supply devices may output different current values. Taking smartphones as an example, the output current value of ordinary power adapters is generally 1000mA, the output current value of power adapters used for fast charging may reach 1500mA or even higher, and the current value output by computers through USB may be 500mA. In addition, the current output by the energy supply device needs to pass through components such as a charging chip (integrated circuit, IC) before finally being input into the battery. During the power transmission process, various factors may cause problems with the charging current charged into the battery, so that the battery cannot obtain normal power. For example, the firmware burned in the charging IC may experience abnormalities such as crashes during operation, and charging abnormalities may also be caused by static interference and other factors. In the embodiment of the present application, the charging current value charged into the battery is obtained for subsequent judgment of charging abnormality, so that charging abnormality can be identified quickly and accurately.

Exemplarily, there are many manners for obtaining the charging current value charged into the battery, which are not specifically limited in this application. For example, the charging current value can be obtained by reading the current node. Taking Android as an example, the current node is "/sys/class/power_supply/battery/BatteryAverageCurrent"; in addition, for a battery with a built-in fuel gauge, The charging current value charged into the battery can be read from the fuel gauge in the battery of the mobile terminal. The advantage of this setting is that the charging current value can be obtained quickly and accurately; in addition, the preset analog-to-digital conversion module (Analog-to -Digital Converter (ADC) reads the charging current value charged into the battery of the mobile terminal, wherein the preset analog-to-digital conversion module is electrically connected to the power management chip, and the power management chip is electrically connected to the battery. The advantage of this setting is that, There is no need to set a fuel gauge in the battery, which saves the manufacturing cost of the battery, and at the same time can accurately obtain the charging current value charged into the battery.

Step 103 , judging whether the charging current value acquired within a preset time period satisfies a preset charging abnormality condition, and if so, determining that charging abnormality occurs.

Wherein, the preset duration may be set according to actual needs, and the embodiment of the present application does not limit its specific value, for example, it may be 5 minutes, or 10 minutes, and so on.

At present, the batteries of most mobile terminals are lithium ion batteries, referred to as lithium batteries, and this application uses lithium batteries as an example for illustration. The charging process of lithium batteries can generally be divided into four stages, trickle charging (low voltage pre-charging), constant current charging, constant voltage charging and charging termination. The typical charging method is: first detect the voltage of the battery to be charged. If the voltage is lower than 3V, it needs to be pre-charged first. The charging current is 1/10 of the set current. After the voltage rises to 3V, it enters the standard charging process; standard charging During the process, constant current charging is carried out with the set current (generally 1000mA). When the battery voltage rises to 4.2V (generally, the battery power can reach 75%), it is changed to constant voltage charging, and the charging voltage is kept at 4.2V. Constant voltage charging The charging current decreases gradually during the process, and when the current drops to 1/10 of the set charging current, the charging ends. The above only provides a typical charging process. In the embodiment of the present application, a charging policy can be set according to the actual situation of the mobile terminal, and is not limited by the above examples.

It can be known from the above examples that different stages in the charging process have different requirements for charging current. In the embodiments of the present application, different preset abnormal charging conditions can be set for different charging stages. For example, in the low-voltage pre-charging stage, the charging current is normally 100mA. When the charging current value obtained within the preset time is less than 10mA or greater than 200mA, it can be considered to meet the preset abnormal charging conditions; in the constant-current charging stage, the charging current The normal value is 1000mA. When the charging current value obtained within the preset time is less than 20mA or greater than 1300mA, it can be considered to meet the preset abnormal charging conditions; in the constant voltage charging stage, the charging current gradually decreases, generally between 100 and 300mA , when the charging current value obtained within the preset time is less than 10mA or greater than 600mA, it can be considered to meet the preset charging abnormal condition; When the current value is greater than 100mA, it can be considered that the preset abnormal charging condition is met.

Of course, unified preset abnormal charging conditions may also be set for different charging stages, which is not limited in this application. For example, during the entire charging process, when the charging current value obtained within the preset time period is less than the preset current threshold (such as 20mA), it can be considered that the preset abnormal charging condition is met; or, when the charging current value obtained within the preset time period When the fluctuation range of the current value exceeds the preset fluctuation range (such as -300mA to 300mA), it indicates that the charging current is very unstable, which is likely to cause damage to the battery, and it can also be considered to meet the preset abnormal charging condition.

In the abnormal charging detection method provided by the embodiment of the present application, when the mobile terminal is in the charging state, it is detected that the abnormal charging detection event is triggered, and the charging current value charged into the battery of the mobile terminal is obtained, and the value obtained within the preset time period is judged. Whether the charging current value satisfies the preset abnormal charging condition, and if so, it is determined that abnormal charging occurs. By adopting the above technical solution, during the charging process of the mobile terminal, it is possible to determine whether charging abnormality occurs according to the charging current charged into the battery, so as to facilitate subsequent corresponding measures to reduce the impact of abnormal charging on the user.

In some embodiments, the judging whether the charging current value acquired within the preset time period satisfies the preset abnormal charging condition includes: judging whether the charging current value acquired within the preset time length is continuously smaller than the first preset current threshold, If yes, it is determined that the preset abnormal charging condition is met. Exemplarily, the process of acquiring the charging current value charged into the battery may be acquired in real time, or may be acquired at a preset acquisition frequency (eg, once every 5 seconds). The first preset current threshold can be determined according to actual conditions (such as battery capacity and charging method, etc.), for example, 20mA. If the charging current value obtained within a preset time period (for example, 2 minutes) is continuously smaller than the first preset current threshold, it can be considered that the preset abnormal charging condition is met. Taking 20mA as an example, the charging current is very small, and there is almost no charge, so it can be confirmed that there is an abnormal charging.

In some embodiments, the judging whether the charging current value acquired within the preset time period satisfies the preset abnormal charging condition includes: judging whether the charging current value acquired within the preset time period is less than the second preset current threshold Whether the number of current values reaches the preset number threshold, if yes, it is determined that the preset abnormal charging condition is met. Wherein, the second preset current threshold may be equal to or different from the first preset current threshold. Take the frequency of obtaining the charging current value once every 5 seconds as an example. When the charging current value is started to be obtained, the initial abnormal number is 0. If the currently collected charging current value is less than 20mA, the abnormal number will be increased by 1. If the abnormal number is within 2 minutes If the preset quantity threshold (for example, 20 times) is reached, it is determined that the preset abnormal charging condition is met. The advantage of this setting is that when most of the charging current values obtained within the preset time period meet the abnormal conditions, it can be considered that the abnormal charging conditions are met, so as to prevent the occurrence of missed judgments.

Further, obtaining the charging current value charged into the battery of the mobile terminal includes: obtaining the charging current value charged into the battery of the mobile terminal through a preset heartbeat detection thread, wherein the heartbeat detection thread every Run once at the first preset time interval. The advantage of this setting is that the heartbeat detection thread can precisely control the timing of obtaining the charging current value, making the determination of abnormal charging more accurate and reliable. Exemplarily, the heartbeat detection thread runs once every 5 seconds, and obtains the current charging state during running, that is, obtains the charging current value charged into the battery.

In some embodiments, after determining that the charging abnormality occurs, it includes: performing a charging abnormality reminder operation; and/or controlling the charging chip to reset. Exemplarily, the specific method of reminding the abnormal charging operation may be to light up the indicator light, play a prompt sound, display text prompts or vibrate, etc., to remind the user that the abnormal charging occurs, and prompt the user to take corresponding measures in time, such as changing the charging mode Wait. Exemplarily, the mobile terminal may also automatically try to resume normal charging, for example, by controlling the reset of the charging IC. Generally, the charging IC is provided with a register for initialization (which can be called an initialization register), and the initialization register can be controlled to reset the charging IC by sending a reset command to the initialization register. In this way, the charging IC is likely to return to normal after reset. work, making charging normal. Optionally, after it is determined that the charging is abnormal, the operation of reminding the abnormal charging and controlling the reset of the charging chip can be carried out at the same time, so as to improve the probability of the mobile terminal returning to normal charging and effectively solve the problem of unsuccessful charging. Of course, after resetting the charging IC, it is also possible to continue to detect whether the charging abnormality disappears, and if it does not disappear, reset again or perform a charging abnormality reminder operation.

In some embodiments, when the mobile terminal is in the charging state, it further includes: controlling the charging chip to reset every second preset time interval, and the second preset time interval is longer than the preset duration. The advantage of this setting is that the charging IC is often reset to reduce the occurrence of abnormal charging. Wherein, the second preset time interval is longer than the preset duration, for example, it may be 15 minutes.

If there is a charging abnormality, the mobile terminal automatically controls the charging chip to reset and try to restore normal charging. Experiments have proved that after the charging chip is reset, the probability of returning to normal charging is very high. Therefore, when abnormal charging is detected, Timely and effective recovery of normal charging, to avoid the impact of abnormal charging on the normal use of users.
