Description

Battery temperature sampling method and wearable device

Technical Field

The present application relates to the field of wearable device technology, and in particular, to a method for battery temperature sampling and a wearable device.

Background

With the increasing development of the functions of the smart watch, the smart watch has become the most common portable tool in people's life. At present, a fuel gauge is generally adopted to charge and discharge management of a battery of a smart watch. When the battery power is insufficient, the fuel gauge cannot work normally, so that the temperature reported by the fuel gauge is inaccurate, and the inaccurate temperature can cause misoperation. Therefore, it is desirable to propose a solution to this problem.

Disclosure of Invention

In view of this, the present application provides a method for sampling a battery temperature, a wearable device, an electronic device, a computer-readable storage medium, and a computer program product, which can avoid a problem of an incorrect operation caused by an inaccurate temperature collected by the first temperature collecting module in an abnormal operating state.

In a first aspect, a method for sampling a temperature of a battery is provided, where the method is applied to a wearable device including a battery, a first temperature acquisition module and a second temperature acquisition module, or applied to an electronic device including: the temperature acquisition device comprises a battery, a first temperature acquisition module and a second temperature acquisition module; the method comprises the following steps:

determining whether a first identifier is acquired within a first preset time, wherein the first identifier is used for identifying a first temperature acquisition module, and the first temperature acquisition module is used for monitoring the temperature of the battery;

when the first identification is not obtained within the first preset time, carrying out temperature acquisition on the battery according to a second temperature acquisition module, and obtaining a first temperature;

and executing over-temperature protection processing based on the first temperature.

The method may be performed by a wearable device or a chip in a wearable device. Alternatively, the above method may be performed by an electronic device (such as a terminal) or a chip in the electronic device. Based on the scheme, whether the first identification is read or not is judged at first, if the first identification is not read within the first preset time, the temperature of the first temperature acquisition module is not adopted for carrying out over-temperature protection processing, the temperature acquisition is carried out on the battery by switching to other temperature acquisition modules (such as the second temperature acquisition module), and then the over-temperature protection processing is carried out on the basis of the first temperature acquired by the second temperature acquisition module, so that the problem of misoperation caused by inaccurate temperature acquired by the first temperature acquisition module under an abnormal working state is solved, and the accuracy of the acquired battery temperature is improved.

In one possible implementation, the method further includes:

when the first identifier is acquired within the first preset time, acquiring the temperature of the battery by using the first temperature acquisition module to acquire a second temperature;

and executing over-temperature protection processing based on the second temperature.

Therefore, under the condition that the first identifier is obtained, it is described that the first temperature acquisition module works normally, the first temperature acquisition module can still be used for sampling the temperature of the battery, and the over-temperature protection processing is executed based on the second temperature acquired by the first temperature acquisition module.

In one possible implementation manner, the performing the over-temperature protection process based on the first temperature includes:

using the battery to power a load when the first temperature is less than or equal to a first temperature threshold.

The first temperature threshold is a safe operating temperature threshold of the battery.

Therefore, when the temperature of the battery is judged to be higher than the first temperature threshold value, the connection between the battery and the load can be disconnected, namely, the battery is stopped to supply power to the load, so that the battery is protected. Of course, when it is determined that the temperature of the battery is not higher than the first temperature threshold, the battery may be continuously used to supply power to the load.

In one possible implementation, when the first temperature is greater than a first temperature threshold, the method further includes:

displaying a first interface, wherein the first interface comprises a first window used for prompting a user that the temperature of the battery is too high.

Therefore, when the first temperature is judged to be higher than the first temperature threshold value, a prompt can be sent to the user through the interface so that the user can make a proper response.

In one possible implementation, the second temperature acquisition module is an NTC temperature sensor. The NTC temperature sensor may be an NTC thermistor of the watch back case. Therefore, by using the NTC thermistor of the watch rear shell to collect the temperature of the battery, a new temperature sampling passage can be avoided, and the cost is saved.

It is to be understood that the second temperature acquisition module may also be a newly introduced temperature sampling module, which is not limited in this embodiment of the application.

In one possible implementation, the first temperature acquisition module is an electricity meter.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

The embodiment of the application is suitable for electronic equipment, and the electronic equipment can be wearable equipment, such as a smart watch, a smart bracelet, a smart ring, a wrist band, a helmet, a headband, glasses or other wearable equipment and the like.

Optionally, the electronic device may also be a terminal device. Terminal devices include, but are not limited to, cell phones, tablets, wireless communication devices, remote terminals, mobile devices, user terminals, handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, in-vehicle devices, and terminal devices in future 5G or 6G networks, and the like.

The wearable device comprises a battery and at least two temperature acquisition paths. For example, the wearable device includes two temperature acquisition paths, specifically, the temperature acquisition path that realizes through first temperature acquisition module promptly to and, the temperature acquisition path that realizes through second temperature acquisition module.

For convenience of description, the embodiments of the present application are described by taking the wearable device as a watch as an example.

Fig. 1 is a schematic view of a wristwatch to which an embodiment of the present application is applied. As shown in fig. 1, the wristwatch includes a dial 101 and a band 102. The user can wear the watch through the wristband 102 and view the content displayed by the watch display through the watch face 101.

In one implementation, in the embodiment of the present application, as shown in fig. 1, the elements related to the temperature control of the battery of the watch may include the following: a microprocessor 103, a watch back case NTC resistor 104 (which may correspond to the second temperature acquisition module), a fuel gauge 105 (which may correspond to the first temperature acquisition module), and a battery NTC resistor 106. Among them, the NTC resistor is a thermistor, also called a Negative Temperature Coefficient (NTC) resistor.

Generally, an electricity meter 105 in a watch is connected to a battery (such as a battery NTC resistor 106) in the watch, and is responsible for charging and discharging management of the watch battery. The fuel gauge 105 may collect the temperature of the battery NTC resistor 106 and report the collected temperature to the microprocessor 103. The battery in the watch is capable of powering the fuel gauge 105.

Alternatively, the microprocessor 103 may be a Micro Controller Unit (MCU). The MCU may receive the battery temperature reported by the fuel gauge 105. In some embodiments, the MCU determines whether a first identifier is obtained within a first preset time period, where the first identifier is used to identify the fuel gauge 105; when the first identifier is not obtained within the first preset time, the NTC resistor 104 of the watch back shell collects the temperature of the battery and obtains a first temperature; and executing over-temperature protection processing based on the first temperature.

It should be noted that the elements shown in the above-mentioned wristwatch are only exemplary, and do not constitute a specific limitation of the wristwatch. In other embodiments of the present application, the watch of FIG. 1 may include more or fewer components than those shown in FIG. 1, or the watch of FIG. 1 may include a combination of some of the components shown in FIG. 1, or the watch of FIG. 1 may include sub-components of some of the components shown in FIG. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination of software and hardware.

It should be understood that fig. 1 only illustrates an example in which the rear case temperature sensor is an NTC resistor, and the embodiments of the present application are not limited thereto. The back shell temperature sensor in the watch may also be of other types. For example, the NTC resistor 104 of the watch back case may be replaced by another type of temperature sensor.

It should be further understood that fig. 1 is only a schematic illustration of an application scenario of the present application, which does not limit the embodiments of the present application, and the present application is not limited thereto.

When the battery is low, the electricity meter 105 in the watch cannot work normally. For example, when the supply voltage of the battery is less than 2.5 volts (V), the fuel gauge 105 cannot operate normally. If the fuel gauge 105 fails to operate normally, the temperature of the battery detected by the fuel gauge 105 may be inaccurate or abnormal, which may cause some problems of malfunction.

For example, when the supply voltage of the battery is less than 2.5V, the fuel gauge cannot work normally, so that the battery temperature collected by the fuel gauge is an abnormal temperature (for example, -40 degrees), and the abnormal temperature of-40 degrees is reported to the microprocessor 103. The microprocessor 103 considers the current battery to be low, but the actual temperature of the battery may not be. At this time, the microprocessor 103 executes subsequent operations, such as controlling the watch to start up, according to the low temperature state of the battery, but the watch cannot be started up normally. It can be understood that inaccurate battery temperature reported by the fuel gauge may also cause other misoperation problems, for example, the battery of the watch cannot be charged normally.

In view of this, the present application provides a method for sampling a battery temperature and a wearable device. According to the temperature sampling method, whether the first identification (used for identifying the first temperature acquisition module) can be detected or not is judged within the first preset time, if the first identification is not obtained within the first preset time all the time, the temperature acquisition is carried out on the battery of the wearable device according to the second temperature acquisition module, the first temperature is obtained, the over-temperature protection processing is carried out based on the first temperature, the misoperation caused when the first temperature acquisition module cannot normally work is avoided, and the stability of the wearable device can be improved.

A schematic diagram of a software system applied to the embodiment of the present application is first described below with reference to fig. 2.

Fig. 2 is a schematic diagram of a software system applied to the embodiment of the present application. As shown in fig. 2, the software system adopting the layered architecture is divided into a plurality of layers, and each layer has a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the software system may be divided into six layers, which are, from top to bottom, an application layer, a system service layer, an algorithm library (library), a hardware abstraction layer HAL, a kernel layer (kernel), and a driver layer (driver).

As shown in fig. 2, the application layer includes a dial, a motion record, a call, and an exercise.

It is understood that part of the application programs are shown in fig. 2, and in fact, the application program layer may also include other application programs, which is not limited in this application. Such as applications that also include information, alarm, weather, stopwatch, compass, timer, flashlight, calendar, payroll, etc.

As shown in fig. 2, the system services layer includes step counting, heart rate services, calories, heart health, and the like.

The algorithm library may include a plurality of algorithm modules. For example, as shown in fig. 2, the algorithm library includes a dimming algorithm module, a sleep algorithm, a wearing algorithm, and the like. The wearing algorithm is used for detecting the wearing state of the watch.

As shown in fig. 2, the hardware abstraction layer includes C + + libraries, storage, display, touch, etc. The C + + library is used for providing system resources for the algorithm library.

It will be appreciated that the hardware abstraction layer shown in fig. 2 is part of the content, and in fact the hardware abstraction layer HAL may also comprise other content, such as a bluetooth module, a GPS module, etc.

As shown in FIG. 2, the kernel layer includes an OS kernel. The OS kernel is used to perform management and scheduling.

The driver layer is used for driving hardware resources. A plurality of driver modules may be included in the driver layer. As shown in fig. 2, the driving layer includes a first temperature acquisition module driver, a second temperature acquisition module driver, a PPG driver, an LCD driver, a motor, and the like.

In some embodiments, the first temperature acquisition module drive may be an electricity meter drive. The OS kernel can monitor the temperature of the battery by driving the scheduling fuel gauge through the fuel gauge.

In some embodiments, the second temperature acquisition module drive may be a back-shell NTC resistive drive. The OS kernel can drive and call the rear shell NTC resistor to collect the temperature of the battery through the second temperature collection module.

The process of temperature sampling according to the embodiment of the present application is described below with reference to fig. 2. The OS kernel schedules the first temperature acquisition module driver to cause the first temperature acquisition module to acquire data (e.g., battery temperature). The first temperature acquisition module driver may return acquired data to the OS kernel. The OS kernel may perform relevant scheduling based on the collected data. When the OS kernel cannot obtain the identifier of the first temperature acquisition module, the second temperature acquisition module can be scheduled to drive so that the second temperature acquisition module can acquire data (for example, sample the temperature of the battery), and perform over-temperature protection processing based on the data acquired by the second temperature acquisition module.

Optionally, when the temperature of the battery is determined to be too high, the OS kernel further reports a result of the too high temperature to the application layer. And the application program layer prompts a user on a UI (user interface) based on the overhigh temperature result reported by the OS kernel so that the user can intuitively know the high-temperature warning of the battery.

It is to be understood that the above describes the software architecture of the wearable device by taking fig. 2 as an example, and the embodiments of the present application are not limited thereto.

Referring to fig. 3 to 7, a method of sampling a battery temperature according to an embodiment of the present application is described.

Fig. 3 shows a schematic flow diagram of a method 300 of battery temperature sampling in an embodiment of the application. The method 300 is applied to a wearable device, and the wearable device comprises a battery, a first temperature acquisition module and a second temperature acquisition module. For example, the method 300 may be applied to the watch shown in FIG. 1. As shown in fig. 3, the method 300 includes:

s310, whether a first identifier is acquired within a first preset time is determined, wherein the first identifier is used for identifying a first temperature acquisition module, and the first temperature acquisition module is used for monitoring the temperature of the battery.

Illustratively, taking a microprocessor (such as 103 in fig. 1) in the watch as an example, the microprocessor may read the first identifier within a first preset time period, and then determine whether the first identifier can be read or detected.

The first identifier may be understood as an identifier of the first temperature acquisition module.

The first temperature acquisition module is responsible for charging and discharging (charging and discharging for short) management of the battery. The first temperature acquisition module can acquire data of the battery, maintain a battery use history record and the like.

Illustratively, the first temperature acquisition module may be the fuel gauge 105 of fig. 1 for monitoring the temperature of the watch battery.

It is understood that the first temperature acquisition module can also realize other management functions of the battery. For example, the first temperature acquisition module may also monitor voltage, charge/discharge current, and the like.

In one implementation, the first temperature acquisition module is an electricity meter. Accordingly, the first identifier is an identifier of the fuel gauge, such as a fuel gauge chip identifier (chip ID).

Generally speaking, when the first temperature acquisition module cannot work normally, the processor cannot read the identifier (corresponding to the first identifier) of the first temperature acquisition module. Based on this, whether this application embodiment is through reading first sign, whether judging first temperature acquisition module normally works, and then whether the temperature of deciding to adopt first temperature acquisition module collection.

According to one implementation mode, if the first identifier can be read, the first temperature acquisition module is indicated to work normally; if the first identifier cannot be read, the first temperature acquisition module is in an abnormal working state, and the temperature acquired by the first temperature acquisition module is inaccurate, so that the subsequent operation, such as temperature judgment of the battery, cannot be executed by using the temperature acquired by the first temperature acquisition module.

The first preset time period may be a preset time value. For example, if the first preset time duration is 15 seconds, the polling may be 15 seconds, that is, the first identifier is read every 15 seconds. It is to be understood that the duration of the first preset duration may depend on the product implementation, and the examples herein are only exemplary descriptions, and the embodiments of the present application are not limited thereto.

The embodiment of the application provides a corresponding solution for determining whether the microprocessor reads the first identifier within the first preset time.

And S320, if the first identifier is not obtained within the first preset time, carrying out temperature acquisition on the battery of the wearable device according to the second temperature acquisition module, and obtaining a first temperature.

The second temperature acquisition module is different from the first temperature acquisition module. Compared with the first temperature acquisition module, the second temperature acquisition module is not originally responsible for charge and discharge management of the battery. In this embodiment of the application, if the first identifier is not obtained within the first preset time period, it is determined that the first temperature acquisition module is abnormal in operation, and at this time, the processor does not perform subsequent processing using the temperature acquired by the first temperature acquisition module, or shields the temperature acquired by the first temperature acquisition module, but switches to the second temperature acquisition module to perform acquisition of the battery temperature.

The embodiment of the present application does not limit the specific form of the second temperature acquisition module. The second temperature acquisition module may be a certain temperature acquisition module existing in the wearable device, or may be a temperature acquisition module added by a new one, which is not limited. For example, the second temperature acquisition module may be the NTC resistor of the watch back case in fig. 1. Therefore, by using the NTC thermistor of the watch rear shell to collect the temperature of the battery, a new temperature sampling passage can be avoided, and the cost can be saved.

And S330, executing over-temperature protection processing based on the first temperature.

In the embodiment of the application, whether the first identifier is read or not is judged firstly, if the first identifier is not read within a first preset time period, the temperature of the first temperature acquisition module is not adopted for carrying out over-temperature protection processing, the temperature acquisition is carried out on the battery by switching to other temperature acquisition modules (such as a second temperature acquisition module), and then the over-temperature protection processing is carried out based on the first temperature acquired by the second temperature acquisition module, so that the problem of misoperation caused by inaccurate temperature acquired by the first temperature acquisition module in an abnormal working state is solved, and the accuracy of the acquired battery temperature is improved.

Optionally, as a possible implementation manner, executing an over-temperature protection process based on the first temperature includes:

when the first temperature is higher than a first temperature threshold value, controlling the battery not to supply power to the load (or controlling the battery to stop discharging), and supplying power to the load by using a charging signal;

and when the first temperature is less than or equal to a first temperature threshold value, using a battery to supply power for the load.

The first temperature threshold is a temperature threshold at which the battery operates safely. The value of the first temperature threshold is not specifically limited in the embodiments of the present application. The value of the first temperature threshold may depend on the battery manufacturer's settings. For example, if the first temperature threshold is 120 ℃, the over-temperature protection process is started when the temperature of the battery is determined to be higher than 120 ℃.

That is, when the temperature of the battery is determined to be higher than the first temperature threshold, the connection between the battery and the load may be disconnected, that is, the battery is stopped to supply power to the load, so as to protect the battery. When the temperature of the battery is judged not to be higher than the first temperature threshold value, the battery can be continuously used for supplying power to the load.

The manner of controlling the battery not to supply power to the load in the embodiment of the present application is not particularly limited. For example, the connection between the battery and the load may be cut off.

For example, the specific process of the microprocessor executing the over-temperature protection processing by the first temperature includes: judging whether the first temperature is greater than a first temperature threshold value; if the first temperature is higher than the first temperature threshold, disconnecting the battery from the load, stopping the discharging process of the battery, and charging the load by using the charging signal; if the first temperature is less than or equal to the first temperature threshold, which indicates that the current temperature does not exceed the safe operating temperature of the battery, the battery may continue to discharge, i.e., charge the load through the battery.

The embodiment of the present application does not limit the specific manner of the over-temperature protection treatment.

Fig. 4 is a circuit schematic of an embodiment of the present application. As shown in fig. 4, the circuit includes a charging chip, an inductor, a load, a battery, and VBUS. The charging chip comprises a control module, a field effect tube Q1, a field effect tube Q2, a field effect tube Q3 and a field effect tube Q4.

The charging chip can be implemented by a buck circuit (or a buck converter circuit). The connection relationship of the elements packaged in the charging chip can refer to the illustration in fig. 4. As shown in FIG. 4, Q1 has one end connected to Q2 and the other end connected to VBUS. VBUS is the chip that charges, can be connected with external power source. One end of Q2 is connected with Q1 in series, and the other end is connected with the inductor. One end of Q3 is connected with the ground, and the other end is connected with the inductor. One end of Q4 is connected to the load and the other end is connected to the Vbat pin of the battery.

One end of the inductor is connected with the load. The inductor is used for realizing a filtering function.

The control module in the charging chip can control the turn-off and turn-on of each field effect transistor contained in the charging chip. According to one implementation mode, the control module is in communication connection with an MCU in the watch and determines to switch on Q4 or a port Q4 based on an instruction of the MCU.

Illustratively, the control module may be notified to turn off Q4 when the MCU determines that the temperature of the battery (e.g., the first temperature, or the second temperature) is higher than a first temperature threshold. After Q4 is turned off, the load can be charged through the charging chip, but the battery cannot be charged through the charging chip. When the MCU determines that the temperature of the battery (e.g., the first temperature, or the second temperature) is less than or equal to the first temperature threshold, the control module may be notified to turn on Q4. After Q4 is turned on, the load can be charged by the battery, and the battery can be charged by the charging chip.

It should be understood that fig. 4 is only illustrated with one load as an example, but the embodiment of the present application is not limited thereto. In fact, more loads may be included in fig. 4.

Optionally, the circuit further comprises an SC fast charging chip. As shown in fig. 4, one end of the SC fast charging chip is connected to the VBUS pin, and the other end is connected to the battery. The SC quick charging chip can be used for realizing quick charging of the battery.

It should be understood that the circuit principle shown in fig. 4 is only one implementation of the over-temperature protection process, and the embodiments of the present application are not limited thereto. In fact, other over-temperature protection treatments may be used by those skilled in the art.

Optionally, as an optional implementation manner, when it is determined that the first temperature is less than or equal to the first temperature threshold, the method further includes: the battery is charged by trickle charging.

Trickle charging refers to the process of supplementing the electric quantity of the battery by a tiny pulse current so as to enable the voltage of the battery to rise. When the temperature of the battery is determined not to be higher than the safe operating temperature threshold and the battery voltage is determined to be lower than the normal operating voltage (for example, the battery voltage is less than 3.5V), the battery may be trickle charged. Alternatively, the normal operating voltage of the battery may be 3.5V-4.4V. It should be understood that the normal operating voltage of the battery is only illustrated as 3.5V to 4.4V, and the embodiments of the present application are not limited thereto. In fact, the normal operating voltage of the battery may have other voltage interval values, which may depend on the manufacturer or product implementation, and the application is not limited in particular.

In addition, the trickle charge is used to protect the battery, and when the battery is in an undervoltage state, if a normal charging mode (for example, a fast charging mode) is used, the battery may be damaged, and the service life of the battery may be affected.

With the trickle charge, the battery voltage may rise back to the normal operating voltage, for example, the power supply voltage of the battery is greater than 3.5V, and then the wearable device may be restarted at this time, and the electricity meter may resume normal operation at this time. After the electricity meter returns to normal operation, the microprocessor can read the identification of the electricity meter.

It should be understood that, during the trickle charging process of the battery voltage, the battery voltage may rise back from 2.5V to 3.5V, during which the battery voltage is not yet turned on, so the electricity meter cannot normally operate, until the voltage of the battery is greater than 3.5V, the battery can normally operate, the wearable device is turned on again, and at this time, the electricity meter can be recovered to be normal.

Of course, if the voltage of the battery is 3.5V-4.4V at the normal operating voltage, when the wearable device is powered on and works normally, the voltage of the battery gradually decreases with the use of the battery power, for example, the voltage drops from 4.4V to 2.5V, and if the wearable device is not powered off and the power supply voltage of the battery for the fuel gauge is not lower than 2.5V, the fuel gauge can still work normally. Stated differently, it is understood that the voltage at which the fuel gauge operates normally is greater than or equal to 2.5V. If the power supply voltage of the battery for the fuel gauge is lower than 2.5V, the fuel gauge cannot work normally.

It should be understood that, the normal operating voltage of the fuel gauge is greater than or equal to 2.5V, which is only an example, and the embodiments of the present application are not limited thereto. In fact, the normal operating voltage of the electricity meter may have other voltage values, which may depend on the manufacturer or product implementation, and the application is not limited in particular.

The above describes a related implementation of temperature acquisition of the battery by the second temperature acquisition module. Of course, when the first identifier is read, the temperature of the battery can still be acquired by the first temperature acquisition module.

Optionally, as an implementation manner, the method 300 further includes:

s340, if the first identifier is acquired within the first preset time, acquiring the temperature of the battery by using the first temperature acquisition module to acquire a second temperature;

and S350, executing over-temperature protection processing based on the second temperature.

That is, if the first identifier is obtained, which indicates that the first temperature collection module is working normally, the first temperature collection module may be used to sample the temperature of the battery. The second temperature refers to the temperature collected by the first temperature collection module. After the second temperature is obtained, the over-temperature protection process may be performed using the second temperature.

It should be understood that the process of performing the over-temperature protection based on the second temperature is similar to the process of performing the over-temperature protection based on the first temperature, for example, by comparing the magnitude relationship between the second temperature and the first temperature threshold to determine whether the battery supplies power to the load, and the detailed process of performing the over-temperature protection based on the second temperature will not be described herein again.

The embodiment of the present application does not specifically limit the timing of reading the first identifier. An implementation mode, after trickle charge is carried out to the battery, along with the rising of battery voltage, battery voltage can rise to normal operating voltage again, for example the supply voltage of battery is greater than 3.5V, wearable equipment can restart this moment, and the fuel gauge can normally work this moment, and microprocessor can read the sign of fuel gauge again (corresponding first sign) so, then can reuse the temperature that the fuel gauge gathered and carry out the excess temperature protection and handle.

The process of temperature sampling is described below in conjunction with the specific example in fig. 5. Fig. 5 is a diagram showing an example of a determination flow of the overheat protection process. As shown in fig. 5, the method 400 includes:

step 401, judging whether the identifier of the electricity meter is acquired.

If the identification of the electricity meter is acquired, executing step 402-B, and if the identification of the electricity meter is not acquired, executing step 402-A.

Alternatively, as described above, a first preset time period may be set, and it is determined whether the identifier of the fuel gauge is obtained within the first preset time period. The description of the first preset duration may refer to the foregoing, and is not repeated herein.

Step 402-A, a first temperature acquisition module is used for acquiring the temperature of the battery to obtain a first temperature.

At step 402-B, an over-temperature protection process is performed based on the temperature collected by the fuel gauge.

In step 403, it is determined whether the first temperature is greater than a first temperature threshold.

If the first temperature is greater than the first temperature threshold, perform step 404; if the first temperature is not greater than the first temperature threshold, step 405 is performed.

In step 404, the battery is controlled to stop discharging, and a charging chip (such as the charging chip shown in fig. 5) is switched to supply power to the system load.

In step 405, the battery is controlled to supply power to the load and trickle charge the battery at the same time.

After step 404 or step 405, the process may return to step 401 and repeat the above process.

Some terms or specific implementations related to the steps in the method 400 may refer to the foregoing description, and are not repeated herein.

In the embodiment of the application, if it is determined that the first temperature is greater than the first temperature threshold, a prompt may be sent to the user through the interface, so that the user may make an appropriate response.

Optionally, when the first temperature is greater than the first temperature threshold, the method 300 further includes:

displaying a first interface, wherein the first interface comprises a first window, and the first window is used for prompting a user that the temperature of the battery is too high.

That is, a high temperature warning of the battery may be issued to the user through the interface when the temperature of the battery is above a temperature threshold for safe operation.

It is to be understood that, here, the description is given by taking an example of issuing a prompt to a user through an interface when the first temperature is greater than the first temperature threshold, but the embodiment of the present application is not limited thereto. For example, if it is determined that the battery temperature (e.g., the second temperature) collected by the first temperature collection module is greater than the first temperature threshold, a prompt may be sent to the user through the interface.

For ease of understanding, the following description is made in conjunction with the interfaces in fig. 6 and 7. It should be understood that the interfaces shown in fig. 6 and 7 are not limiting on the embodiments of the present application.

FIG. 6 illustrates an example diagram of a watch interface. As shown in fig. 6, a window 501 pops up in the watch interface, and the content displayed in the window 501 is "the battery temperature is too high". A close control 502 may also be included in window 501. If the user has read the content in window 501, the user can click on control 502 to close window 501.

It should be understood that fig. 6 is only described by taking a watch as an example, but the embodiments of the present application are not limited thereto.

Optionally, when the watch establishes a communication connection with the terminal, the first window may be displayed through an interface of the terminal.

In particular, other input devices 230 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, a light mouse (a light mouse is a touch-sensitive surface that does not display visual output, or is an extension of a touch-sensitive surface formed by a touch screen), and the like. The other input devices 230 are connected to other input device controllers 271 of the I/O subsystem 270 and are in signal communication with the processor 280 under the control of the other input device controllers 271.

The touch screen 240 may be used to display information input by or provided to the user and various menus of the apparatus 500, and may also accept user input. The touch screen 240 may include a display panel 241 and a touch panel 242. The display panel 241 may be a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Mini light-emitting diode (Mini LED), a Micro light-emitting diode (Micro LED), a Micro OLED (Micro OLED), or a quantum dot light-emitting diode (QLED).

Touch panel 242, also referred to as a display screen, a touch-sensitive screen, etc., may collect contact or non-contact operations (e.g., operations performed by a user on or near touch panel 242 using any suitable object or accessory such as a finger, a stylus, etc., and may also include somatosensory operations; the operations include single-point control operations, multi-point control operations, etc.) and drive the corresponding connected devices according to a preset program. Alternatively, the touch panel 242 may include two parts of a touch detection device and a touch controller. The touch detection device detects gestures of a user, namely touch direction and gesture, detects signals brought by touch operation, and transmits the signals to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into information that can be processed by the processor, and then sends the information to the processor 280, and receives and executes commands sent from the processor 280. In addition, the touch panel 242 may be implemented by various types such as resistive, capacitive, infrared, and surface acoustic wave, and the touch panel 242 may be implemented by any technology developed in the future. Further, touch panel 242 may overlay display panel 241, a user may operate on or near touch panel 242 overlaid on display panel 241 according to content displayed on display panel 241 (the display content includes, but is not limited to, a soft keyboard, a virtual mouse, virtual keys, icons, etc.), touch panel 242 detects the operation on or near touch panel 242, and transmits the operation to processor 280 through I/O subsystem 270 to determine user input, and processor 280 then provides corresponding visual output on display panel 241 through I/O subsystem 270 according to the user input. Although in fig. 5, the touch panel 242 and the display panel 241 are implemented as two separate components to implement the input and output functions of the apparatus 500, in some embodiments, the touch panel 242 and the display panel 241 may be integrated to implement the input and output functions of the apparatus 500.

Prompt information for wearing style, wearing status, etc., and historical information in the form of visual (numbers, tables, graphics) or audible (synthesized voice or tones) of the detected heart rate may be provided on the display panel 241 under program control of the processor 280. As one non-limiting example, a visual graph may be displayed showing the heart rate calculated every 5 minutes during a previous fixed time interval (e.g., 1 hour) or after the exercise session has ended (as determined by its indication from the user). Average heart rate information or statistical information of heart rate during a previous time period or time periods may also be provided on the display panel 241 under the control of the processor 280. As another example, the current heart rate value may be provided on the display panel 241 as a "real-time" heart rate value that is periodically (e.g., every second) displayed to the user during the course of an exercise program in progress.

PPG module 251, which includes a light emitter and a light sensor. The heart rate is measured through the PPG module and is based on the absorption principle that the material was to light, and the blood vessel of skin is shone to the light emitter in the PPG module of electronic equipment, and light that light sensor received and is passed through from the skin. Because different volumes of blood in the blood vessel absorb different green light, the blood flow is increased and the green light absorption amount is increased when the heart beats, and the blood flow is reduced when the heart beats in the gap, and the absorbed green light is reduced. Thus, heart rate can be measured from the absorbance of blood. In operation, the light emitter may transmit a light beam to the skin of the user, and the light beam may be reflected by the skin of the user and received by the light sensor. The light sensor may convert the light into an electrical signal indicative of its intensity. The electrical signal may be in analog form and may be converted to digital form by an analog-to-digital converter. The digital signal from the analog-to-digital converter may be a time domain PPG signal that is fed to processor 280. The output of the accelerometer may also be converted to digital form using an analog-to-digital converter. The processor 280 may receive the digitized signals from the light sensors and digitize the accelerometer output signals of the accelerometers and may process these signals to provide a heart rate or wear status output signal to a memory device, visual display, audible annunciator, touch screen, or other output indicator.

A temperature collection module 253 for collecting temperature. In some embodiments, temperature acquisition module 253 includes two temperature acquisition paths, such as an electricity meter and a watch back case NTC resistor. The fuel gauge is used to collect the temperature of the battery of the device 500. In some embodiments, if the processor 280 does not obtain the first identifier within the first preset time period, the temperature of the battery is collected according to the NTC resistor of the watch back case, and a first temperature is obtained; and executing over-temperature protection processing based on the first temperature.

As one type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), detect the magnitude and direction of gravity when stationary, and can be used for vibration recognition related functions (such as pedometer, tapping) and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which may be further configured for the apparatus 500, further description is omitted here.

The device 500 may also include a buzzer 252, the buzzer 252 may generate vibrations as directed by the processor 280.

The audio circuit 260 may transmit the converted signal of the received audio data to the speaker 261, and the converted signal is converted into a sound signal by the speaker 261 and output; on the other hand, the microphone converts the collected sound signals into signals, which are received by the audio circuit 260 and converted into audio data, which are output to the RF circuit 210 for transmission to, for example, a cellular phone, or to the memory 220 for further processing.

The external devices used by the I/O subsystem 270 to control input and output may include other devices, an input controller 271, a sensor controller 272, and a display controller 273.

It is noted that other input control device controllers 271 may be connected to any one or more of the above devices. The display controller 273 in the I/O subsystem 270 receives signals from the touch screen 240 and/or transmits signals to the touch screen 240. After the touch screen 240 detects the user input, the display controller 273 converts the detected user input into an interaction with the user interface object displayed on the touch screen 240, i.e., implements a human-computer interaction. The sensor controller 272 may receive signals from one or more sensors 251 and/or transmit signals to one or more sensors 251.
