[0001] The present application relates to the technical field of batteries, and particularly to an electronic device, a battery expansion detection method, a device, a medium and a program product. Background Art

[0002] With the wide use of silicon anode batteries in mobile terminals, power tools and new energy vehicles, the stability problem of silicon anode batteries has become particularly important. The charge and discharge cycles of silicon anode batteries will cause slight expansion of the batteries. In order to better protect the batteries, it is necessary to detect the expansion state of the batteries so that the charge and discharge strategy can be adjusted in time at the initial stage of slight expansion of the batteries, and the service life of the batteries can be improved.

[0003] However, currently, the expansion detection of batteries generally sets multiple pressure sensors. After the battery expands and squeezes the pressure sensors, the expansion state of the battery is determined according to the magnitude of the pressure. However, in this way, when the battery expands and bulges, the pressure sensors at some positions may not be able to contact the expanded battery, resulting in inaccurate detection of battery expansion. Summary of the Invention

[0004] Based on this, in view of the above technical problems, it is necessary to provide an electronic device, a battery expansion detection method, a device, a medium and a program product that can improve the accuracy of battery expansion detection.

[0005] In a first aspect, the present application provides an electronic device, which includes a battery, an elastically stretchable monitoring belt, a tension sensor and a processor;

[0006] Wherein, both ends of the monitoring belt are respectively arranged on both sides of the detection surface of the battery, so that the monitoring belt is in contact with the detection surface of the battery;

[0007] One end of the monitoring belt is fixed, and the other end is connected to the tension sensor, and the tension sensor is used to detect the target tension value of the monitoring belt;

[0008] The processor is connected to the tension sensor, and is used to receive the target tension value sent by the tension sensor and determine the expansion degree of the battery according to the target tension value.

[0009] In a second aspect, the present application also provides a battery expansion detection method, which is applied to the electronic device according to any item in the first aspect above. The method includes:

[0010] Obtain the target tension value detected by the tension sensor for the monitoring belt;

[0011] Determine the expansion degree of the battery according to the target tension value.

[0012] In a third aspect, the present application also provides a battery expansion detection device, which is applied to an electronic device according to any one of the above first aspects. The device includes:

[0013] An acquisition module, configured to acquire a target tensile force value obtained by a tensile force sensor detecting a monitoring belt;

[0015] In a fourth aspect, the present application also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps of the method according to any one of the above second aspects are implemented.

[0016] In a fifth aspect, the present application also provides a computer program product, including a computer program. When the computer program is executed by a processor, the steps of the method according to any one of the above second aspects are implemented.

[0017] For the above-mentioned electronic device, battery expansion detection method, device, medium and program product, the electronic device includes a battery, an elastically stretchable monitoring belt, a tensile force sensor and a processor. Among them, both ends of the monitoring belt are respectively arranged on both sides of the detection surface of the battery, so that the monitoring belt is in contact with the detection surface of the battery. One end of the monitoring belt is fixed, and the other end is connected to a tensile force sensor for detecting the target tensile force value of the monitoring belt. The processor is connected to the tensile force sensor and is configured to receive the target tensile force value sent by the tensile force sensor and determine the degree of expansion of the battery according to the target tensile force value. In this way, by detecting the target tensile force of the monitoring belt in contact with the detection surface of the battery and calculating the degree of expansion of the battery according to the target tensile force value, since the monitoring belt can better contact the detection surface of the battery, it avoids the problem that other types of sensors may not be able to contact the battery due to battery expansion, resulting in inaccurate detection. Therefore, the accuracy of the detection result of the degree of battery expansion is higher. Description of the Drawings

[0029] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0031] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] In this application, unless otherwise clearly specified or limited, terms such as "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In this application, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0035] Currently, the detection of battery swelling generally involves setting multiple pressure sensors. After the battery swells and squeezes the pressure sensors, the swelling state of the battery is determined according to the magnitude of the pressure. However, in this method, after the battery swells and bulges, since the battery body area may be separated from the middle frame or the battery cover, the pressure sensors at some positions may not be able to contact the swollen battery, resulting in inaccurate detection of battery swelling.

[0036] In view of this, this application calculates the swelling degree of the battery by detecting the target pulling force of the monitoring belt in contact with the detection surface of the battery. Since the monitoring belt can better contact the detection surface of the battery, it avoids the problem that other types of sensors may not be able to contact the battery due to battery swelling, resulting in inaccurate detection. Therefore, the detection result of the battery swelling degree is more accurate.

[0037] Such as Figure 1As shown, it shows a schematic structural diagram of an electronic device provided by an embodiment of the present application. The electronic device 100 includes a battery 10, an elastically stretchable monitoring band 20, a tensile force sensor 30, and a processor 40.

[0038] Among them, both ends of the monitoring band 20 are respectively arranged on both sides of the detection surface of the battery 10, so that the monitoring band 20 is in contact with the detection surface of the battery 10; one end of the monitoring band 20 is fixed, and the other end is connected to the tensile force sensor 30. The tensile force sensor 30 is used to detect the target tensile force value of the monitoring band 20; the processor 40 is connected to the tensile force sensor 30, and is used to receive the target tensile force value sent by the tensile force sensor 30, and determine the degree of expansion of the battery 10 according to the target tensile force value.

[0039] Among them, the monitoring band 20 selects an elastically stretchable material, which conforms to the accurate Hooke's law.

[0040] Among them, the electronic device 100 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc.

[0041] Optionally, the electronic device 100 may further include a display screen for displaying information, a middle frame assembly for mounting the display screen on one side, a circuit main board 50 mounted on the middle frame assembly, a small board 60 mounted on the middle frame assembly, and a rear cover snap-connected to the other side of the middle frame assembly. The above display screen, middle frame, and rear cover are not shown in the figure.

[0042] Among them, the display screen can be a liquid crystal display screen (English: Liquid Crystal Display, abbreviated: LCD) or an organic light-emitting diode display screen (English: Organic Light-Emitting Diode, abbreviated: OLED) and other types of display screens, for displaying information and pictures.

[0043] The material of the middle frame assembly can be metals such as magnesium alloy, aluminum alloy, stainless steel, etc. Of course, the material is not limited to this, and it can also be others. The middle frame assembly can be placed between the display screen and the rear cover. The middle frame assembly can be used to carry the display screen. The middle frame assembly and the rear cover are snap-connected to form the external contour of the electronic device 100, and an accommodation cavity is formed inside. The accommodation cavity can be used to accommodate electronic components such as cameras, circuit main boards 50, small boards 60, batteries 10, processors 40, and various types of sensors in the electronic device 100.

[0044] The circuit main board 50 is installed in the accommodation cavity and can be installed at any position in the accommodation cavity. The processor 40 can be arranged on the circuit main board 50. One, two or more of functional components such as a motor, a microphone, a speaker, a receiver, a headphone jack, a universal serial bus interface (USB interface), a camera, a distance sensor, an ambient light sensor, and a gyroscope can also be integrated on the circuit main board 50. Meanwhile, the display screen can be electrically connected to the circuit main board 50.

[0045] The battery 10 is installed in the accommodation cavity and can be installed at any position in the accommodation cavity. The battery 10 can be electrically connected to the circuit main board 50 to enable the battery 10 to supply power to the electronic device 100. A power management circuit can be arranged on the circuit main board 50. The power management circuit is used to distribute the voltage provided by the battery 10 to each electronic component in the electronic device 100 such as the display screen.

[0046] The rear cover can be made of the same material as the middle frame assembly. Of course, other materials can also be used. The rear cover can be integrally formed with the middle frame assembly. In some embodiments, the rear cover can wrap the middle frame assembly and can carry the display screen. Structures such as a rear camera hole and a fingerprint recognition module installation hole can be formed on the rear cover.

[0047] Wherein, one end of the detection surface of the battery 10 can be the circuit main board 50 and the other end can be the small board 60. Both ends of the monitoring belt 20 are respectively arranged at both ends of the detection surface of the battery 10, that is, one end is arranged on the circuit main board 50 and the other end is arranged on the small board 60, and the initial state is in contact with the detection surface of the battery 10. The tension sensor 30 can be used to detect the tension received by the monitoring belt 20. Optionally, as Figure 2 shown, in the initial state, which is the state before the battery 10 expands, at this time, the tension received by the monitoring belt 20 is F0, and F0 = 0N. During the use of the battery 10, when the battery 10 expands, without significant change in the total cross-sectional perimeter of the battery 10, the thickness of the battery 10 in the Z direction will increase, as Figure 2 the state of the battery 10 after expansion in. At this time, since the monitoring belt 20 is an elastically stretchable monitoring belt, therefore, as the battery 10 expands, the tension received by the deformed monitoring belt 20 is F1, and F1 is also the target tension value.

[0048] The processor 40 receives the target tension value and can obtain the change in the tension of the monitoring belt 20 during the expansion of the battery 10 according to the target tension value. By the change in the tension, the deformation length of the monitoring belt can be determined. Modeling calculation or constructing a fitting curve is performed according to the relationship between the deformation length of the monitoring belt and the thickness of the battery 10 in the Z direction, so that the change in the thickness of the battery 10 in the Z direction, that is, the expansion degree of the battery 10, can be determined according to the change in the tension.

[0049] Optionally, the tensile force sensor 30 may be a flat tensile force sensor, such as Figure 3 shown in Figure 3 , or a strain gauge type tensile force sensor that measures the tensile force through strain gauges pasted on the elastomer, or a piezoelectric tensile force sensor that detects the tensile force by using the charge change generated by the piezoelectric material when stressed, or a semiconductor strain gauge tensile force sensor that measures the tensile force by using the resistance change of the semiconductor material. It can be selected according to different application scenarios and accuracy requirements, and the present application does not limit this.

[0050] Those skilled in the art can understand that Figure 1 the structure shown in Figure 1 is only a block diagram of some structures related to the solution of the present application, and does not constitute a limitation on the electronic device to which the solution of the present application is applied. The specific electronic device may include more or fewer components than those shown in the figure, or combine some components, or have different component arrangements.

[0051] In the above embodiment, the electronic device includes a battery, an elastically stretchable monitoring belt, a tensile force sensor, and a processor. Among them, both ends of the monitoring belt are respectively arranged on both sides of the detection surface of the battery, so that the monitoring belt is in contact with the detection surface of the battery. One end of the monitoring belt is fixed, and the other end is connected to the tensile force sensor for detecting the target tensile force value of the monitoring belt. The processor is connected to the tensile force sensor and is used to receive the target tensile force value sent by the tensile force sensor and determine the degree of expansion of the battery according to the target tensile force value. In this way, by detecting the target tensile force of the monitoring belt in contact with the detection surface of the battery, the degree of expansion of the battery is calculated according to the target tensile force value. Since the monitoring belt can better contact the detection surface of the battery, it avoids the problem that other types of sensors may not be able to contact the battery due to battery expansion, resulting in inaccurate detection. Therefore, the detection result of the degree of battery expansion is more accurate.

[0052] In one embodiment, one end of the monitoring belt 20 is arranged on the first circuit board of the electronic device 100, and the other end of the monitoring belt 20 is arranged on the second circuit board of the electronic device 100; the first circuit board is either the main board 50 or the small board 60, and the second circuit board is the other one of the main board 50 or the small board 60.

[0053] Among them, as Figure 1 shown in Figure 1 , the first circuit board and the second circuit board are arranged on both sides of the battery 10. One end of the monitoring belt 20 is arranged on the first circuit board of the electronic device, and the other end of the monitoring belt 20 is arranged on the second circuit board of the electronic device, so that the monitoring belt 20 can be in full contact with the battery 10. The main board 50 is the core component of the electronic device, and the small board 60 is a PCB board arranged on the other side of the battery 10.

[0054] In one embodiment, such as Figure 4As shown, the top view and side view of the electronic device 100 are shown. The tension sensor 30 includes a first tension sensor S1 and a second tension sensor S2. The monitoring belt 20 includes a first monitoring belt M and a second monitoring belt N. The first monitoring belt M is connected to the first tension sensor S1, and the second monitoring belt N is connected to the second tension sensor S2.

[0055] Optionally, taking the first circuit board as the main board 50 and the second circuit board as the small board 60 as an example for illustration, the first tension sensor S1 and the second tension sensor S2 can be arranged on the first circuit board. The other ends of the first monitoring belt M and the second monitoring belt N are fixed to the second circuit board. The tension received by the first monitoring belt M is detected by the first tension sensor S1, and the tension received by the second monitoring belt N is detected by the second tension sensor S2.

[0056] It can be understood that the first tension sensor S1 and the second tension sensor S2 can also be arranged on the second circuit board, and the other ends of the first monitoring belt M and the second monitoring belt N are fixed to the first circuit board.

[0057] Optionally, the tension sensor 30 can also include a third tension sensor and a fourth tension sensor. One of the first tension sensor and the third tension sensor is arranged on the first circuit board, and the other is arranged on the second circuit board. One end of the first monitoring belt M is connected to the first tension sensor, and the other end of the first monitoring belt M is connected to the third tension sensor. Correspondingly, one of the second tension sensor and the fourth tension sensor is arranged on the first circuit board, and the other is arranged on the second circuit board. One end of the second monitoring belt N is connected to the second tension sensor, and the other end of the second monitoring belt N is connected to the fourth tension sensor. That is, the detection method can be changed from fixing one end and measuring the other end to measuring both ends through tension sensors. According to the target tension values measured at both ends of each monitoring belt, the actual tension value of the corresponding monitoring belt is calculated, so as to obtain the actual deformation length of each monitoring belt.

[0058] In the above embodiments, the expansion state of the battery is detected by two monitoring belts, the detection surface of the battery covered is more comprehensive, and the accuracy of the battery expansion detection result is higher.

[0059] In one embodiment, the first monitoring belt M and the second monitoring belt N are symmetric with respect to the center line of the detection surface. Among them, the center line of the detection surface is as Figure 4As shown by the dashed line in the figure, optionally, since some current electronic devices include a wireless charging coil, and the wireless charging coil is usually located at the center line of the detection surface of the battery 10, therefore, the first monitoring band M and the second monitoring band N can be symmetrically arranged on the two half parts of the battery 10, axially symmetric about the center line of the detection surface of the battery 10, so as to avoid the position of the wireless charging coil. It can be understood that the positions of the first monitoring band M and the second monitoring band N can also be adjusted according to the position of the wireless charging coil of the actual electronic device, and the embodiments of the present application do not limit this.

[0060] In the above embodiment, the detection of the expansion state of the battery is realized through the first monitoring band and the second monitoring band. The detection method is simple, and at the same time, it does not affect the overall Z-axis height of the machine.

[0061] In one embodiment, the electronic device includes a housing, the battery 10 includes a plurality of battery surfaces, the detection surface is the battery surface close to the housing among the plurality of battery surfaces, and the area of the detection surface is greater than or equal to the area of other battery surfaces.

[0062] Optionally, during the expansion of the battery, the surface with a larger area of the battery surface expands more significantly. Therefore, using the largest battery surface that is close to the housing among the battery surfaces as the detection surface can better judge the expansion degree of the battery 10.

[0063] In an exemplary embodiment, as Figure 5 shown, a method for detecting battery expansion is provided, which is applied to an electronic device such as Figure 1 described above. The method includes:

[0064] Step 501, obtain the target tension value detected by the tension sensor for the monitoring band.

[0065] Among them, the target tension value is the tension of the monitoring band detected by the tension sensor in the current state. Optionally, there can be one monitoring band, or the monitoring band can include multiple ones. The present application takes the above Figure 3 two monitoring bands as an example for illustration. The tension sensor includes a first tension sensor and a second tension sensor, and the monitoring band includes a first monitoring band and a second monitoring band; the first monitoring band is connected to the first tension sensor, and the second monitoring band is connected to the second tension sensor; the above steps are as Figure 6 shown and may include:

[0066] Step 601, obtain the first tension value measured by the first tension sensor.

[0067] Among them, the first tension value is the first tension received by the first monitoring band.

[0068] Step 602, obtain the second tension value measured by the second tension sensor.

[0069] Among them, the second tensile value is the second tensile force received by the second monitoring belt.

[0070] Step 502: Determine the degree of expansion of the battery according to the target tensile value.

[0071] Optionally, the degree of expansion of the battery is also the change in the Z-direction thickness of the battery. As Figure 7 shown, the steps to determine the degree of expansion of the battery include:

[0072] Step 701: Determine the first deformation length of the first monitoring belt according to the first tensile value, and determine the second deformation length of the second monitoring belt according to the second tensile value.

[0073] Since the first monitoring belt and the second monitoring belt conform to Hooke's law, according to Hooke's law F = -kx, where F is the tensile value, k is the elastic coefficient, and x is the deformation length. That is, the first deformation length of the first monitoring belt can be calculated according to the first tensile value, and the second deformation length of the second monitoring belt can be calculated according to the second tensile value.

[0074] Step 702: Determine the expanded thickness of the battery according to the first deformation length and the second deformation length.

[0075] After determining the first deformation length at the position of the first monitoring belt of the battery and the first deformation length at the position of the second monitoring belt, the maximum cross-sectional thickness of the battery at the position of the first monitoring belt and the maximum cross-sectional thickness at the position of the second monitoring belt can be calculated according to the first deformation length and the second deformation length. Optionally, the maximum cross-sectional thickness of the battery can be calculated according to the deformation length through the following methods. The corresponding relationship table between the deformation length and the degree of expansion can be queried according to the deformation length to obtain the corresponding degree of expansion. The preset corresponding relationship table between the deformation length and the degree of expansion can be established based on multiple sets of corresponding relationships between the deformation length and the degree of expansion measured for the battery under different degrees of expansion. The corresponding relationship table can be saved in a database or a file for convenient query of the corresponding degree of expansion after detecting the deformation length.

[0076] Optionally, the method of constructing a fitting curve can also be used. According to the above-mentioned multiple sets of corresponding relationships between different deformation lengths and degrees of expansion, a fitting curve is constructed in advance and saved in a file. After detecting the deformation length, the corresponding degree of expansion is obtained by fitting according to the deformation length and the fitting curve.

[0077] Optionally, the degree of expansion of the battery can also be calculated by a modeling method, that is, based on multiple sets of corresponding relationships between the deformation lengths and degrees of expansion measured for the battery under different degrees of expansion, a model is established, and the model is trained until it is qualified. After detecting the deformation length, the deformation length is input into the model, and the corresponding degree of expansion is obtained according to the output of the model.

[0078] AsFigure 8 As shown, that is, the maximum cross-sectional thickness Hm of the battery at the first monitoring band position and the maximum cross-sectional thickness Hn of the battery at the second monitoring band position are determined. Due to the distance information between the first monitoring band and the second monitoring band and the premise that the cross-sectional perimeter of the battery remains unchanged, the maximum thickness H of the battery expansion can be calculated, that is, the expansion degree of the battery in the current state. Optionally, calculation can be performed by modeling with sample data of different expansion degrees obtained, or a fitting curve can be constructed for calculation. The embodiments of the present application do not limit this.

[0079] After determining the expansion degree of the battery in the current state, the processor can dynamically adjust the charging and discharging applications of the battery according to the expansion degree of the current state, so as to obtain the best balance between performance and life. For example, the more fully the battery is discharged, the greater the battery expansion. Therefore, when the current expansion degree of the battery indicates that the expansion is too large, it can be controlled to avoid over-discharging the battery.

[0080] In the embodiments of the present application, please refer to Figure 9 , which shows a flowchart of a battery expansion detection method provided by the embodiments of the present application. The battery expansion detection method includes the following steps:

[0081] Step 901, obtain a first tensile force value measured by a first tensile force sensor.

[0082] Step 902, obtain a second tensile force value measured by a second tensile force sensor.

[0083] Step 903, determine a first deformation length of the first monitoring band according to the first tensile force value, and determine a second deformation length of the second monitoring band according to the second tensile force value.

[0084] Step 904, determine the thickness of the battery expansion according to the first deformation length and the second deformation length.

[0085] It should be understood that although the steps in the flowcharts involved in the above-described embodiments are sequentially shown according to the indication of the arrows, these steps do not necessarily have to be executed in the order indicated by the arrows. Unless there is a clear description in this article, the execution of these steps does not have a strict order limit, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-described embodiments may include multiple steps or multiple stages. These steps or stages do not necessarily have to be executed at the same moment, but can be executed at different moments.
