Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, in particular to a processing method. BACKGROUND

[0002] For most electronic devices, a power supply component with charging and discharging functions, i.e., a battery component, is configured.

[0003] However, the output voltage of the battery component is not constant. As the power of the battery component decreases, the output voltage of the battery component also decreases, and the internal impedance, i.e., the internal resistance, also increases. In particular, when the power of the battery component is low, i.e., the battery component is in a low-voltage state, the internal resistance is even larger. At this time, if the required current of the electronic device is large, the voltage drop generated by the internal resistance of the battery component is large, and the power supply voltage that the battery component can provide for the electronic device is even smaller, which may cause the electronic device to abnormally power off and affect the user's experience.

[0066] The embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0067] In order to make the above objectives, characteristics and advantages of the present application more apparent, obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0068] As described in the background section, when the battery assembly is at a low voltage, its internal resistance will increase as the voltage decreases, which will result in a large voltage drop of the battery assembly if the required current of the electronic device is large, i.e., the electronic device is in a high-power state. Therefore, the supply voltage that the battery assembly can provide for the electronic device will be smaller. If the supply voltage that the battery assembly can provide is smaller than the protection voltage of the power management module, the voltage protection of the power management module will be triggered, the electronic device will be powered off, and the electronic device will be abnormally powered off, which will affect the user's experience.

[0069] Based on the above, the present application provides a processing method, as shown in FIG. 1, Figure 1 Figure 1 A flowchart of a processing method provided by the present application is shown in FIG. 1. The processing method includes:

[0070] ​S1: Obtain a first target voltage of the target component based on at least a first voltage of the target component and a voltage drop generated by the target component corresponding to the first voltage. The first target voltage is a minimum voltage value maintained by the target component for the working system of the electronic device to run at maximum power. The first voltage represents the available energy of the target component, that is, the first voltage can represent the available power of the target component. Based on the above, the first target voltage is a voltage limit of the target component for the working system of the electronic device to run at maximum power. If the voltage of the target component is less than the first target voltage, the working system of the electronic device cannot maintain its maximum power running under the power supply of the target component. If the voltage of the target component is greater than or equal to the first target voltage, the working system of the electronic device can maintain its maximum power running. It should be noted that the target component is a power supply component of the electronic device, that is, a battery of the electronic device. For example, the target component can be a silicon negative battery, but the present application does not limit this, and the specific condition is determined accordingly. It should also be noted that the first voltage can be a plurality of voltage values when the target component is in a low voltage state, for example, a plurality of voltage values when the voltage of the target component is below 3.4V, such as 3.4V, 3.3V, 3.2V, 3.1V, 3.0V, etc. The first target voltage is one of the plurality of voltage values when the voltage of the target component is below 3.4V.

[0071] S2: When the current voltage of the target component is less than the first target voltage, switch the working system of the electronic device from the first working state to the second working state, and the working power of the second working state is lower than that of the first working state. That is, the running power of the working system of the electronic device can be switched based on the first target voltage of the target component. When the current voltage of the target component is lower than the first target voltage, the working system of the electronic device can be switched from a high-power running state to a low-power running state, so that the remaining energy of the target component, or the remaining power of the target component, can maintain the working system of the electronic device to continue to work, thereby effectively avoiding the electronic device from abnormally powering off, and continuing to use the remaining power of the battery component in a low voltage state. The working system of the electronic device can be switched from the first working state to the second working state manually by the user, and can be automatically switched by the working system based on the user's settings. Specifically, it can be manifested as screen brightness reduction, screen refresh frequency reduction, and super power saving mode, etc.

[0072] It should be noted that if the working power of the working system of the electronic device is reduced, the required current of the working system of the electronic device will also be reduced accordingly, and the power supply voltage required by the target component will also be reduced, so the protection voltage of the power management system in the electronic device can be determined based on the working power of the working system of the electronic device. The higher the working power, the higher the protection voltage, and the lower the working power, the lower the protection voltage. Therefore, when the current voltage of the target component is less than the first target voltage, the working system of the electronic device is switched from the first working state to the second working state, and the working system of the electronic device can continue to operate based on the power supply of the target component.

[0073] From the above, the processing method can obtain the minimum voltage that can maintain the working system of the electronic device to operate at maximum power based on the first voltage of the target component and the voltage drop corresponding to the first voltage. The working state of the working system of the electronic device can be switched when the voltage of the target component is less than the minimum voltage, that is, in a low-voltage state, and the working power of the working system of the electronic device is reduced to make the working system of the electronic device continue to work under the power supply of the target component even if the voltage of the target component is less than the first target voltage, that is, the target component is in a low-voltage state. Only the power is reduced, so that the abnormal power failure of the electronic device can be inhibited, and the low-voltage power of the target component can still be used.

[0074] It should be noted that, as Figure 2 shown, Figure 2 In order to discharge at 0.2 times the rated capacity of the current (0.2C), the residual energy comparison table of germanium battery (Ge) and fourth-generation silicon battery (Gen4 Si) and fifth-generation silicon battery (Gen5 Si) corresponding to different voltages, according to Figure 2 It can be seen that the residual energy of the low-voltage region of the silicon negative electrode battery is more and more, and the silicon negative electrode battery is a battery that uses silicon as the negative electrode material, has the advantage of high energy density, and has wide application prospect in the field of batteries. Therefore, the processing method described in the present application can continue to use the low-voltage power of the battery component, which is helpful to the effective use of the energy of the silicon negative electrode battery, and further helps the further development of the silicon negative electrode battery.

[0075] It also needs to be explained that the available energy and internal resistance of different target components in low voltage state can be different, or the available energy and internal resistance of different target components in low voltage state can not be the same, and in addition, the internal resistance of the target component also gradually increases with the use and aging of the target component, that is, the first target voltage of the target component is not a fixed value, but a variable value, which cannot be fixed. As known from the above, in the processing method, the first target voltage of the target component is obtained based on the first voltage of the target component and the voltage drop of the target component corresponding to the first voltage, that is, the first target voltage of the target component is at least obtained according to the available energy and internal resistance of the target component in low voltage state, that is, the first target voltage of the target component is tailored based on its own parameters and the state at the moment, and can change with the aging of the target component, so as to effectively inhibit the abnormal power failure of the electronic device, and also can adjust the first target voltage with the aging of the target component, so as to ensure the sufficient use of low voltage power of the target component.

[0076] In an embodiment of the present application, as shown in Figure 3 , Figure 3 a flow chart of a processing method provided by the present application, the first target voltage of the target component is obtained based on at least the first voltage of the target component and the voltage drop generated by the target component corresponding to the first voltage, including:

[0077] S11: obtaining the first target voltage of the target component based on the first voltage of the target component and the voltage drop generated by the target component corresponding to the first voltage.

[0078] Among them, as shown in Figure 4 , Figure 4 a flow chart of obtaining the first target voltage in a processing method provided by the present application, the first target voltage of the target component is obtained based on the first voltage of the target component and the voltage drop generated by the target component corresponding to the first voltage, including:

[0079] S111: obtaining the first impedance, the first impedance is the line impedance of the charge-discharge path of the target component. It needs to be explained that usually, the line impedance of the charge-discharge path is a fixed value, which is not affected by external factors, so the first impedance is only obtained in the calculation process of the first target voltage once, and it is not necessary to obtain the above first impedance every time, which simplifies the calculation process of the first target voltage.

[0080] S112: obtaining the second impedance, the second impedance is the internal impedance of the target component corresponding to the first voltage. It needs to be explained that the internal impedance of the target component corresponding to the first voltage is the resistance when the voltage of the target component is the first voltage and the target component has no current output and input.

[0081] S113: Obtain a voltage drop generated by the target component corresponding to the first voltage based on a product of a sum of the first impedance and the second impedance and the target current. The target current is an output current of the target component when the target component maintains the working system to run at the maximum power.

[0082] S114: Obtain a difference between the first voltage and the voltage drop generated by the target component corresponding to the first voltage.

[0083] S115: Compare the difference with a protection voltage of a power management system of the electronic device. If the difference is greater than the protection voltage and a difference between the difference and the protection voltage is not greater than a first preset value, the first voltage corresponding to the difference is the first target voltage. The power management system controls the electronic device to power off based on a current voltage of the target component. The target component is connected to the power management system through the charging and discharging path. The power management system is also connected to the working system. It should be noted that the first target voltage is one of a plurality of voltage values when the target component is in a low voltage state, and is the minimum voltage value when the target component maintains the working system to run at the maximum power. Therefore, the calculation process of the first target voltage should be from the minimum value of the plurality of voltage values when the target component is in the low voltage state to a higher voltage, until a voltage value meeting the requirement is calculated as the first target voltage. Therefore, the voltage value greater than the calculated value in the plurality of voltage values when the target component is in the low voltage state can meet the requirement. However, the first target voltage is required to be the minimum voltage value meeting the requirement. Therefore, the first target voltage calculated should be the voltage value with the minimum difference between the protection voltage in the plurality of voltage values meeting the requirement. Therefore, the difference is greater than the protection voltage, and the difference between the difference and the protection voltage is not greater than the first preset value. The first voltage corresponding to the difference is the first target voltage. It should be further noted that the application does not limit the specific value of the first preset value, which depends on the calculation accuracy of the first target voltage. The higher the calculation accuracy, the smaller the value of the first preset value. Conversely, the value of the first preset value is larger. The specific value is determined according to the situation.

[0084] In the embodiment, if the first impedance is denoted as , the second impedance is denoted as , the target current is denoted as , the first voltage is denoted as , and the first target voltage is denoted as , then . For example, if , the protection voltage is , , based on , , the calculation is ; based on , , the calculation is ; based on , ,calculate: Based on the above calculations, it can be determined that when the voltage of the target component is not less than 3.2V, the target component can maintain the electronic device's operating system at maximum power. That is, the value of the first target voltage can be 3.2V.

[0085] As can be seen from the above, the voltage drop of the target component corresponding to the first voltage includes both the voltage drop caused by its internal resistance and the voltage drop caused by the line impedance between it and the power management system. That is, the above voltage drop is obtained by taking into account multiple factors that affect the voltage drop, which can more accurately obtain the voltage drop of the target component corresponding to the first voltage, and thus more accurately obtain the first target voltage.

[0086] In one embodiment of this application, such as Figure 5 As shown, Figure 5 A flowchart of a processing method provided in this application for obtaining a second impedance, wherein obtaining the second impedance includes:

[0087] S31: The target component is in a non-charging / discharging state, and the current entering the target component through the charging / discharging path is controlled to be 0. It should be noted that the above-mentioned non-charging state of the target component can be achieved by the electronic device being powered by an external power supply, rather than by the target component itself, thus placing the target component in a non-charging state. For example, this could be achieved by plugging an external charging device into the electronic device. It should also be noted that... Figure 6 As shown, Figure 6 The diagram illustrates the structure of the electronic device, which includes a target component 100, a power management system 200, and a working system 300. The power management system comprises a first part 202 and a second part 204. The first part 202 can be connected to an external charging device 400. The charging device 400 can be connected to the working system sequentially via the first part 202 and the second part 204, thereby providing power to the working system when the target component is not charging. The charging device 400 can also be connected to the target component 100 via the first part 202 to provide input current to the target component 100. It should also be noted that the first part 202 of the power management system further includes switches Q1, Q2, and Q3, as well as a converter control unit, a power switch (BatFET), and a fuel gauge. The power switch controls the current entering the target component 100, and the fuel gauge acquires the target component's state of health (SOH) and various voltages.

[0088] S32: After the first preset time, the voltage of the target component is obtained, denoted as a second voltage. It should be noted that the current entering the target component through the charging and discharging channel is 0, and the second voltage is read after the first preset time, so as to read the second voltage of the target component after the voltage of the target component is stable, thereby ensuring the accuracy of the second voltage. It should be further noted that the voltage of the target component is a routine function of the power management system, and will not be repeated here.

[0089] S33: Based on the first correspondence between the voltage of the target component and the second resistance and the second voltage, the second resistance is obtained. It should be noted that the above-mentioned first correspondence is the correspondence between the voltage of the target component and the second resistance when the target component is in a non-charging and discharging state and the input and output currents are 0, that is, the second voltage is one of the first voltages.

[0090] As shown in Figure 7 , Figure 7 , a flowchart for obtaining the first impedance in a processing method provided by the present application, obtaining the first resistance includes:

[0091] S41: After obtaining the second voltage, the current entering the target component through the charging and discharging channel is controlled to be a first preset current, and the value of the first preset current is greater than 0 and less than a second preset value.

[0092] S42: After the second preset time, the voltage of the target component is obtained, denoted as a third voltage, and the voltage of one end of the charging and discharging channel away from the target component is obtained, denoted as a fourth voltage. It should be noted that in order to make the voltage difference between the third voltage and the fourth voltage only caused by the line impedance of the charging and discharging channel, and eliminate the influence of the internal resistance change of the target component on the voltage difference between the third voltage and the fourth voltage, the first preset current is a small current less than the second preset value, for example, the value of the first preset current can be 100 mA, so that when the target component inputs the first preset current, the internal resistance change of the target component within the second preset time will not cause the internal resistance change of the target component, or the change is very small and can be ignored.

[0093] S43: Based on the ratio of the difference between the third voltage and the fourth voltage to the first preset current, the first impedance is obtained. Based on the above, the third voltage is denoted as , the fourth voltage is denoted as , the first preset current is denoted as , and the second impedance , so as to obtain the second impedance.

[0094] It should be noted that controlling the current entering the target component is a routine function of the power switch, and obtaining the voltage of the target component and the charging and discharging channel is a routine function of the power management system, and will not be repeated here.

[0095] The processing method described in the above embodiment is to obtain the first target voltage of the target component without considering the aging of the target component. However, the aging of the target component is inevitable with the long-term use of the target component. Therefore, in an embodiment of the present application, as shown in Figure 8 Figure 8 a flowchart of a processing method provided by the present application, the first target voltage of the target component is obtained based on the first voltage of the target component and the voltage drop generated by the target component corresponding to the first voltage, and the obtaining of the first target voltage of the target component further includes:

[0096] S116: obtaining a health status indicator of the target component, for example, obtaining the health status indicator of the target component by using a coulometer, denoted as .

[0097] S117: comparing the product of the above difference and the health status indicator with the protection voltage, if the product is greater than the protection voltage and the difference between the product and the protection voltage is not greater than a first preset value, the first voltage corresponding to the product is the first target voltage. That is, when the target component ages, the health status indicator of the target component needs to be considered in the process of obtaining the first target voltage. As described in the above embodiment, when the target component does not age, the first target voltage obtained based on the above difference can be 3.2V. However, if the target component ages, the first target voltage obtained by comparing the product of the above difference and the health status indicator with the protection voltage will change, for example , , , and the first target voltage is 3.3V.

[0098] If the target component ages, in addition to the first target voltage of the aged target component obtained by the health status indicator described in the above embodiment, the first target voltage of the aged target component can also be obtained by updating the relationship between the second voltage and the second resistance. Specifically, in an embodiment of the present application, as shown in Figure 9 Figure 9 a flowchart of obtaining the second impedance in a processing method provided by the present application, the obtaining of the second impedance includes:

[0099] S34: updating the corresponding relationship between the voltage of the target component and the second resistance from the first corresponding relationship to the second corresponding relationship. It should be noted that the same voltage of the target component, the second resistance obtained based on the second corresponding relationship is greater than the second resistance obtained based on the first corresponding relationship, that is, the second corresponding relationship considers the aging of the target component, so that the second resistance obtained based on the second corresponding relationship is the second resistance of the aged target component.

[0100] S35: the target component is in a non-charging and discharging state, and the current flowing into the target component through the charging and discharging channel is 0. ​​

[0101] S36: After the first preset time, the voltage of the target component is obtained, denoted as a second voltage.

[0102] S37: Based on the second correspondence relationship and the second voltage, the second resistance is obtained to obtain the second target voltage considering the aging of the target component, so that the working state of the working system of the electronic device can be accurately controlled based on the first target voltage, abnormal power-off is avoided, and the available energy in the low voltage region of the target component can be effectively utilized.

[0103] In an embodiment of the present application, as shown in Figure 10 Figure 10 A flowchart for updating the relationship between the voltage of the target component and the second resistance to the second correspondence relationship in a processing method provided by the present application is provided, and the correspondence relationship between the voltage of the target component and the second resistance is updated from the first correspondence relationship to the second correspondence relationship, including:

[0104] S51: The target component is in a non-charging and discharging state, and the current flowing into the target component through the charging and discharging channel is 0.

[0105] S52: After the third preset time, the voltage of the target component is obtained, denoted as a fifth voltage.

[0106] S53: Then, the current flowing into the target component through the charging and discharging channel is controlled to be a second preset current, and the value of the second preset current is greater than 0 and less than a third preset value.

[0107] S54: After the fourth preset time, the voltage of the target component is obtained, denoted as a sixth voltage.

[0108] S55: Based on the ratio of the difference between the fifth voltage and the sixth voltage to the second preset current, the second resistance corresponding to the fifth voltage is obtained.

[0109] S56: Based on the fifth voltage and the corresponding second resistance, the correspondence relationship between the voltage of the target component and the second resistance is updated from the first correspondence relationship to the second correspondence relationship. As can be seen, the second correspondence relationship is obtained based on the real-time voltage of the target component and the second resistance corresponding to the real-time voltage when the target component is in a non-charging and discharging state, so the second correspondence relationship can represent the relationship between the voltage of the target component and its internal resistance at the moment, and thus when the target component ages, the second correspondence relationship can represent the relationship between the voltage of the aged target component and its internal resistance, and the relationship between the voltage of the target component and the second resistance can be updated.

[0110] ​In an embodiment of the present application, the processing method further comprises: if the first target voltage obtained based on the first corresponding relationship is different from the first target voltage obtained based on the second corresponding relationship, taking the larger one of the first target voltages obtained based on the two corresponding relationships as the first target voltage of the target component, so as to ensure that the first target voltage can maintain the working system of the electronic device to operate at the maximum power.

[0111] In an embodiment of the present application, as shown in Figure 11 Figure 11 a flowchart of a processing method provided by the present application, the first target voltage of the target component is obtained based on at least the first voltage of the target component and the voltage drop generated by the target component corresponding to the first voltage, which comprises:

[0112] S12: obtaining the first target voltage based on the sum of the first voltage of the target component, the voltage drop generated by the target component corresponding to the first voltage and the voltage error.

[0113] wherein, the voltage error is obtained based on:

[0114] the capacity loss error of the target component, the capacity loss error being the ratio of the difference between the current capacity of the target component and the design capacity corresponding to the target component and the design capacity, if the capacity loss error is less than 0, the voltage error is obtained based on the capacity loss error, the voltage error is greater than 0, and the voltage error is positively correlated with the capacity loss. For example, if based on the capacity loss curve of the target component, the capacity of the target component after being charged 900 times should be 95%, but the capacity of the target component after being actually charged 800 times is reduced to 95%, then there is a capacity loss error, so the error can be calculated as i.e. the error can be the ratio of the difference between the actual charging times and the design charging times and the design charging times. After obtaining the ratio, the relationship between the ratio and the voltage error can be obtained to obtain the voltage error.

[0115] ​It should be noted that since the capacity loss error is the ratio of the difference between the current capacity of the target component and the corresponding design capacity and the design capacity, when the capacity loss error is less than 0, it means that the actual capacity loss is higher, and the target component can provide a lower power supply voltage. Therefore, when the capacity loss error is less than 0, the first target voltage is obtained based on the first voltage of the target component and the sum of the voltage drop and the voltage error generated by the first voltage of the target component, that is, the first target voltage needs to be corrected according to the capacity loss error of the target component to ensure the accuracy of the first target voltage. It should be noted that if the capacity loss error is greater than 0, it means that the actual capacity loss of the target component is lower than the design value, and the target component can provide a higher power supply voltage. The first target voltage calculated can meet the requirement of maintaining the working system of the electronic device to run at the maximum power, and it does not need to be corrected.

[0116] In an embodiment of the present application, as shown in Figure 12 , Figure 12 a flowchart of a processing method provided by the present application, the processing method further comprises:

[0117] S3: obtaining a second target voltage of the target component based on at least the first voltage and the voltage drop generated by the first voltage of the target component, the second target voltage being the minimum voltage value of the target component for maintaining the working system to run in the second working state, and if the current voltage of the target component is less than the second target voltage, the power management system of the electronic device controls the electronic device to power off. Wherein the target component is connected to the power management system through the charging and discharging path, and the power management system is also connected to the working system.

[0118] It should be noted that the principle and process of obtaining the second target voltage of the target component based on at least the first voltage and the voltage drop generated by the first voltage of the target component are the same as the principle and process of obtaining the first target voltage of the target component based on at least the first voltage and the voltage drop generated by the first voltage of the target component in the foregoing embodiment, which will not be repeated here. As can be seen, the processing method can also obtain the power-off voltage of the electronic device based on the available energy of the target component and the corresponding internal resistance, so that the power-off voltage of the electronic device can be obtained in advance, and the user can be informed of the power-off time of the electronic device in advance, providing a better user experience.

[0119] In an embodiment of the present application, as shown in Figure 12 , the processing method further comprises:

[0120] S4: during the process that the working system works in the first working state and the voltage of the target component decreases to the first target voltage, the display power of the electronic device is gradually reduced from the first power to the second power.

[0121] S5: In the process that the voltage of the target component gradually decreases from the first target voltage to the second target voltage when the working system works in the second working state, the display power of the electronic device gradually decreases from the second power to the third power.

[0122] For example, in the process that the voltage of the target component decreases to the first target voltage, the display power of the electronic device decreases from 100% to 1%. For another example, in the process that the voltage of the target component decreases from the first target voltage to the second target voltage, the display power of the electronic device gradually decreases from 1% to 0.9%, 0.8%,..., 0.0%, or in the process that the voltage of the target component decreases from the first target voltage to the second target voltage, the display of the original 1% remaining power is converted to the display of 10% remaining power, and then in the process that the first target voltage decreases to the second target voltage, the display power of the electronic device gradually decreases from 10% to 9%, 8%,..., 0%.

[0123] As can be seen from the above, the processing method can refine the power display state of the electronic device when the working system is in different working states, so that the user can reasonably arrange the use of the electronic device through the power display in the different working states, and provide convenience for the user in the use process. Especially when the working system of the electronic device is in the second working state, the user can more clearly judge the power-off time of the electronic device according to the power display, so as to avoid the sudden power-off of the electronic device and affect the user's use experience.
