[0081] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0082] Figure 1 A schematic diagram of a battery processing method according to an exemplary embodiment Figure 1 ,like Figure 1 As shown, the battery processing method mainly includes the following steps:

[0083] In step 101, in the current charge and discharge cycle, a first discharge voltage of the battery is obtained; wherein the first discharge voltage is the battery voltage when a charging instruction is detected;

[0084] In step 102, when the first discharge voltage is less than a preset voltage threshold, the battery is controlled to charge and discharge based on a first discharge cut-off voltage;

[0085] In step 103, when the number of charge and discharge cycles of the battery controlled based on the first discharge cut-off voltage reaches a target number of cycles corresponding to the first discharge cut-off voltage, the charge and discharge of the battery is controlled based on a second discharge cut-off voltage; wherein the second discharge cut-off voltage is greater than the first discharge cut-off voltage.

[0086] It should be noted that the battery processing method proposed in the present disclosure can be applied to electronic devices. Here, the electronic device may include: terminal devices, for example, mobile terminals or fixed terminals. Among them, mobile terminals may include: mobile phones, tablet computers, laptops, wearable electronic devices and other devices. Fixed terminals may include: desktop computers, smart TVs, vehicle-mounted devices, etc. In other embodiments, the battery processing method can also be applied to applications installed on electronic devices.

[0087] In other embodiments, the battery processing method in the embodiment of the present disclosure may be configured in a battery processing device, and the battery processing device may be provided in an electronic device, and the embodiment of the present disclosure does not limit this. It should be noted that the execution subject of the embodiment of the present disclosure may be a central processing unit (CPU) in an electronic device in terms of hardware, and may be a related background service in the electronic device in terms of software, and this is not limited.

[0088] It is understandable that as an energy storage device, the cycle life of the battery affects the user experience and cost of use. As users' demand for battery energy density increases, a certain amount of silicon material is usually added to the negative electrode of the battery, so that the silicon material can play a greater role in the discharge capacity of the battery during the discharge phase, thereby increasing the discharge capacity of the battery.

[0089] Here, silicon is a material widely used in the field of batteries. Silicon has important applications in the positive electrode, negative electrode and electrolyte of batteries. In the actual application of batteries, the application of silicon materials can improve the energy density of batteries, extend the service life of batteries, and have higher safety.

[0090] It should be noted that the discharge cut-off voltage is one of the important factors affecting the battery cycle life. Usually, if the discharge cut-off voltage is set too high, although it can ensure the safety of the battery, it will lead to a reduction in the battery's charging capacity, thereby reducing the battery's cycle life; and if the discharge cut-off voltage is set too low, although it can increase the battery's discharge capacity, it will cause the battery to over-discharge, thereby accelerating battery aging and reducing the cycle life. Therefore, the battery's discharge cut-off voltage needs to be continuously adjusted throughout the battery's life cycle.

[0091] Here, the discharge cut-off voltage, also called the discharge end voltage, refers to the voltage value at which the discharge stops after the voltage reaches a certain level during the battery discharge process. The discharge cut-off voltage plays an important role for the battery. The discharge cut-off voltage can effectively protect the battery and avoid damage to the battery due to excessive discharge. At the same time, the discharge cut-off voltage can also improve the battery's service life and reliability, thereby ensuring that the battery can continue to provide a stable power supply for various electronic devices.

[0092] Therefore, in order to meet the user's demand for a long battery cycle, a preset voltage threshold is first set in the embodiment of the present disclosure, and the user's usage habits for the battery are monitored in real time, that is, the first discharge voltage of the battery when a charging instruction is detected in the current charge and discharge cycle is obtained, and it is determined whether the first discharge voltage is less than the preset voltage threshold, so as to determine whether the user's usage habits are conducive to meeting the long battery life requirements. When the user's usage habits are not conducive to meeting the long battery life requirements, the battery's charge and discharge voltages are adjusted in a timely manner to ensure that the battery is in a healthy state.

[0093] Here, the battery can be a power battery or an energy storage battery, which is not limited in the embodiments of the present disclosure.

[0094] In some embodiments, in order to ensure that the battery is in a healthy state, when the first discharge voltage is less than a preset voltage threshold, in addition to adjusting the first discharge voltage, a prompt message "If not charged, the health of the battery may be affected" will be output, thereby not only reminding the user to charge the battery, but also prompting the user to adjust the battery usage habits.

[0095] It should be noted that when it is detected that the battery has a need for deep discharge, that is, when the first discharge voltage is less than a preset voltage threshold, the battery can be controlled to be charged and discharged based on the first discharge cut-off voltage.

[0096] Here, the preset voltage threshold may be set based on experience or obtained based on experiments, and the embodiments of the present disclosure are not limited to this.

[0097] For example, it is known from experience that when the battery is charged and discharged according to the pre-discharge voltage of 3.5V, the battery is in a healthy state, so 3.5V can be set as the preset voltage threshold.

[0098] It is understandable that the lower the discharge voltage of the battery, the more electricity the battery discharges, which is more conducive to improving the discharge capacity of the battery. Therefore, in the embodiment of the present disclosure, when the first discharge voltage is less than the preset voltage threshold, the first discharge voltage is reduced to the first discharge cut-off voltage, and then the battery is controlled to charge and discharge based on the first discharge cut-off voltage, so as to obtain a larger discharge capacity.

[0099] Here, the first discharge cut-off voltage may be set based on experience or obtained based on experiments, and the embodiments of the present disclosure are not limited to this.

[0100] It should be explained that long-term deep discharge can easily damage the battery. Therefore, when the number of cycles of charging and discharging the battery controlled based on the first discharge cut-off voltage reaches the target number of cycles corresponding to the first discharge cut-off voltage, the charging and discharging of the battery is controlled based on the second discharge cut-off voltage, wherein the second discharge cut-off voltage is greater than the first discharge cut-off voltage.

[0101] It is understandable that, in order to ensure the service life of the battery, when the number of charge and discharge cycles of the battery reaches the target number of cycles corresponding to the first discharge cut-off voltage, it is necessary to increase the first discharge cut-off voltage to the second discharge cut-off voltage, that is, to control the charge and discharge of the battery based on the second discharge cut-off voltage.

[0102] Here, the first discharge cut-off voltage and the target number of cycles are in a corresponding relationship, that is, one first discharge cut-off voltage corresponds to one target number of cycles. It should be noted that in order to ensure that the battery has a large discharge capacity and maintains a healthy state, it is necessary to monitor the discharge voltage of the battery throughout its life cycle.

[0103] Therefore, in actual use, it is necessary to obtain the first discharge voltage of the battery in the current charge and discharge cycle in real time, compare the first discharge voltage with the preset voltage threshold, and control the charge and discharge of the battery based on the first discharge cut-off voltage when the first discharge voltage is less than the preset voltage threshold. When the number of cycles of charge and discharge of the battery controlled based on the first discharge cut-off voltage reaches the target number of cycles corresponding to the first discharge cut-off voltage, the charge and discharge of the battery is controlled based on the second discharge cut-off voltage; wherein the second discharge cut-off voltage is greater than the first discharge cut-off voltage, so that the first discharge voltage of the battery can be continuously monitored, and the charge and discharge of the battery can be controlled based on the first discharge cut-off voltage or the second discharge cut-off voltage, so that the battery has a large discharge capacity while meeting the long life requirements of the battery.

[0104] In the disclosed embodiment, a first discharge voltage of a battery in a current charge and discharge cycle is monitored in real time, wherein the first discharge voltage is the battery voltage when a charging instruction is detected; the charge and discharge cycle strategy of the battery is continuously optimized, and when the first discharge voltage is less than a preset voltage threshold, the charge and discharge of the battery is controlled based on a first discharge cut-off voltage, so that the battery can release a larger discharge capacity, and at the same time, when the number of charge and discharge cycles of the battery controlled based on the first discharge cut-off voltage reaches a target number of cycles corresponding to the first discharge cut-off voltage, the charge and discharge of the battery is controlled based on a second discharge cut-off voltage, wherein the second discharge cut-off voltage is greater than the first discharge cut-off voltage, thereby reducing the number of charge and discharge cycles of the battery, which is conducive to meeting the long cycle life requirement of the battery.

[0105] In this way, the disclosed embodiment continuously optimizes the battery's charge and discharge cycle strategy by monitoring the user's usage habits, thereby maximizing the large capacity benefits of silicon materials while ensuring that the battery has a long service life.

[0106] In some embodiments, Figure 2 A schematic diagram of a battery processing method according to an exemplary embodiment Figure 2 ,like Figure 2 As shown, the method also includes:

[0107] In step 104, when the first discharge voltage is greater than the preset voltage threshold, the next charge and discharge cycle is entered.

[0108] It should be noted that, since appropriate shallow discharge of the battery is beneficial to the health of the battery life, in the embodiment of the present disclosure, by obtaining the first discharge voltage of the battery in the current charge and discharge cycle in real time, when the first discharge voltage is greater than or equal to the preset voltage threshold, there is no need to adjust the first discharge voltage, and enter the next charge and discharge cycle.

[0109] It is understandable that in order to ensure that the battery has a large discharge capacity and maintains a healthy state, it is necessary to monitor the discharge voltage of the battery throughout its life cycle. Therefore, in actual use, it is necessary to obtain the first discharge voltage of the battery in the current charge and discharge cycle in real time, compare the first discharge voltage with the preset voltage threshold, and continue to obtain the first discharge voltage in the next charge and discharge cycle when the first discharge voltage is greater than the preset voltage threshold.

[0110] Exemplarily, 3.5V is set as the preset voltage threshold. When the first discharge voltage of the battery in the current charge and discharge cycle is obtained to be 3.6V, there is no need to adjust the first discharge voltage, and the next charge and discharge cycle begins.

[0111] In the embodiment of the present disclosure, when the first discharge voltage is greater than the preset voltage threshold, the next charge and discharge cycle is entered, which is beneficial for monitoring the discharge voltage of the battery throughout its life cycle to ensure that the battery has a large discharge capacity and maintains a healthy state.

[0112] In some embodiments, Figure 3 A schematic diagram of a battery processing method according to an exemplary embodiment Figure 3 ,like Figure 3 As shown, the method also includes:

[0113] In step 105, historical usage parameters of the battery are obtained;

[0114] In step 106, the preset voltage threshold is determined based on the historical usage parameter;

[0115] The historical usage parameters include at least: the remaining power when charging and discharging are triggered during the historical usage.

[0116] It should be noted that since users have different usage habits for batteries, the performance parameters of each battery vary. In order to increase the discharge capacity of the battery and meet the long life requirements of the battery, it is necessary to formulate different charge and discharge cycle strategies for the battery according to the user's usage habits.

[0117] Therefore, in the embodiment of the present disclosure, the historical usage parameters of the battery are first obtained; and then the preset voltage threshold is determined based on the historical usage parameters; wherein the historical usage parameters at least include: the remaining power when charging and discharging are triggered during the historical usage process.

[0118] It is understandable that by acquiring the historical usage parameters of the battery, the remaining power of the battery before charging can be determined, thereby determining the user's usage habits for the battery. Based on the user's usage habits, the preset voltage threshold is determined.

[0119] Specifically, after determining the remaining power of the battery before charging by the user, the current discharge voltage of the battery is measured to obtain a discharge voltage corresponding to the user's usage habits, and the discharge voltage is determined as a preset voltage threshold.

[0120] Here, after detecting that the user's usage habits have changed, the preset voltage threshold will also change.

[0121] In some embodiments, by obtaining the historical usage parameters of the battery, it is determined that the user has bad usage habits for the battery. In order to optimize the battery charge and discharge cycle strategy, the preset voltage threshold can be adjusted according to the user's usage habits. For example, if the user is accustomed to charging the battery only when the remaining power is low, the preset voltage threshold can be set higher, so that the battery is in a healthy state, which is conducive to meeting the battery's long life requirements.

[0122] For example, when it is determined that the remaining power of the battery is 30%, and the user is used to charging the battery, the discharge voltage of the battery is obtained to be 3.5 V. When it is determined that charging and discharging the battery at 3.5 V is not likely to damage the health of the battery, 3.5 V can be set as the preset voltage threshold.

[0123] In the embodiment of the present disclosure, the historical usage parameters of the battery are obtained; and then the preset voltage threshold is determined based on the historical usage parameters; wherein the historical usage parameters at least include: the remaining power when charging and discharging are triggered during the historical usage process, so that the battery charging and discharging strategy can be optimized by judging the user's usage habits, which is beneficial to improving the battery life.

[0124] In some embodiments, the method further comprises:

[0125] Based on a preset mapping relationship, determining the number of available cycles corresponding to the first discharge cut-off voltage from preset available cycle numbers;

[0126] Based on the available number of cycles corresponding to the first discharge cut-off voltage and a first preset adjustment coefficient, a target number of cycles corresponding to the first discharge cut-off voltage is obtained.

[0127] It should be explained that in order to ensure the long life of the battery, it is necessary to control the number of cycles of charging and discharging the battery according to the first discharge cut-off voltage so that the number of cycles is within the range of the target number of cycles corresponding to the first discharge cut-off voltage. Therefore, in the embodiment of the present disclosure, before obtaining the target number of cycles corresponding to the first discharge cut-off voltage, it is necessary to first determine the available number of cycles corresponding to the first discharge cut-off voltage.

[0128] Here, the number of available cycles can represent the maximum number of cycles that can ensure that the battery performance parameters are in a normal state during the charge and discharge cycle of the battery.

[0129] It is understandable that in order to quickly determine the number of available cycles corresponding to each discharge voltage, a mapping relationship between the discharge voltage and the number of available cycles can be preset. In this way, after obtaining the first discharge cut-off voltage, the number of available cycles corresponding to the first discharge cut-off voltage can be determined from the preset number of available cycles based on the mapping relationship.

[0130] Here, the mapping relationship may be set based on experience or obtained based on experiments, and the embodiments of the present disclosure are not limited to this.

[0131] It should be noted that, when the number of cycles of charging and discharging the battery according to the first discharge cut-off voltage reaches the number of available cycles corresponding to the first discharge cut-off voltage, it is not conducive to improving the service life of the battery. Therefore, a first preset adjustment coefficient can be set first, and then based on the number of available cycles corresponding to the first discharge cut-off voltage and the first preset adjustment coefficient, the target number of cycles corresponding to the first discharge cut-off voltage is determined.

[0132] Here, the first preset adjustment coefficient can be set arbitrarily, and the embodiment of the present disclosure is not limited to this.

[0133] In some embodiments, the first preset adjustment coefficient may be any value between 0.1-0.99, such as 0.8.

[0134] Exemplarily, the calculation formula for the target number of cycles corresponding to the first discharge cut-off voltage may be as follows:

[0135] n=k×yy (1)

[0136] In formula (1), n ​​represents the target number of charge and discharge cycles corresponding to the first discharge cut-off voltage, k represents the first preset adjustment coefficient, and yy represents the available number of cycles corresponding to the first discharge cut-off voltage.

[0137] When the first preset adjustment coefficient k is set to 0.8, the first discharge cut-off voltage of the battery 1When the voltage is 2.8V, the number of cycles that the battery can use is yy 1 is 200 times. Based on the above formula (1), the target charge and discharge cycle number n corresponding to the first discharge cut-off voltage can be calculated: 1 It is 160 times.

[0138] In the embodiment of the present disclosure, based on a preset mapping relationship, the available number of cycles corresponding to the first discharge cut-off voltage is first determined from the preset available number of cycles; then based on the available number of cycles corresponding to the first discharge cut-off voltage and the first preset adjustment coefficient, the target number of cycles corresponding to the first discharge cut-off voltage is obtained. In this way, in the embodiment of the present disclosure, the charge and discharge strategy of the battery can be adjusted for different first discharge cut-off voltages, thereby improving the discharge capacity of the battery while controlling the number of charge and discharge of the battery to ensure the service life of the battery.

[0139] In some embodiments, the method further comprises:

[0140] Starting from a first limit voltage within a preset adjustment range, the voltage is increased in sequence according to a first preset amplitude to obtain respective preset discharge voltages;

[0141] The battery is charged and discharged according to each of the preset discharge voltages to obtain a preset number of available cycles corresponding to each of the preset discharge voltages;

[0142] A mapping relationship between each of the preset discharge voltages and the corresponding preset available cycle number is established.

[0143] It should be explained that in order to improve the accuracy of each available cycle number, the battery can be subjected to charge and discharge cycle tests according to multiple discharge voltages to obtain the available cycle number corresponding to each discharge voltage.

[0144] It should be noted that the characteristic of silicon material is that it has a larger battery capacity in a certain low voltage range. Therefore, the embodiment of the present disclosure obtains multiple preset discharge voltages from a preset adjustment range, and then charges and discharges the battery according to each of the preset discharge voltages to obtain a preset number of available cycles corresponding to each of the preset discharge voltages.

[0145] It is understandable that each preset discharge voltage corresponds to a preset number of available cycles. In order to obtain the preset number of available cycles corresponding to each preset discharge voltage, the battery needs to be charged and discharged according to each preset discharge voltage, so as to obtain the preset number of available cycles corresponding to each preset discharge voltage.

[0146] Here, the preset adjustment range can be set arbitrarily as long as it corresponds to the low voltage segment in which the silicon material works, and the embodiments of the present disclosure are not limited to this.

[0147] It should be explained that in order to facilitate statistics of multiple discharge voltages within the preset adjustment range, a first preset amplitude can be set so that starting from the first limit voltage within the preset adjustment range, the amplitude is increased in sequence according to the first preset amplitude to obtain each preset discharge voltage.

[0148] Here, the first limit voltage may be the lowest discharge voltage within a preset adjustment range.

[0149] Meanwhile, the first preset amplitude may be set arbitrarily, and the embodiments of the present disclosure are not limited thereto.

[0150] For example, when a silicon negative electrode battery is subjected to a charge and discharge cycle test, the battery charging mode is set to remain unchanged, the preset adjustment range is set to 2.8-3.8V, the first preset amplitude is 0.1V, and multiple preset discharge voltages can be obtained starting from the first limit voltage 2.8V at an increasing rate of 0.1V. In order to obtain the preset number of available cycles corresponding to each preset discharge voltage, the battery needs to be charged and discharged according to each preset discharge voltage.

[0151] It should be noted that, in order to facilitate the rapid acquisition of the number of available cycles corresponding to the first discharge cut-off voltage, a mapping relationship can be established between the preset discharge voltage and the corresponding preset number of available cycles, so that after the first discharge cut-off voltage is obtained, the preset number of available cycles corresponding to the first discharge cut-off voltage can be determined from multiple preset number of available cycles based on the mapping relationship.

[0152] In the embodiment of the present disclosure, starting from the first limit voltage within the preset adjustment range, the voltage is first increased in sequence according to the first preset amplitude to obtain various preset discharge voltages; then the battery is charged and discharged according to each of the preset discharge voltages to obtain the preset number of available cycles corresponding to each of the preset discharge voltages; finally, a mapping relationship between each of the preset discharge voltages and the corresponding preset number of available cycles is established. In this way, by obtaining the mapping relationship, different available cycle numbers corresponding to different first discharge cut-off voltages can be obtained, which is conducive to optimizing the battery charge and discharge strategy.

[0153] In some embodiments, the charging and discharging of the battery according to each of the preset discharge voltages to obtain the preset number of available cycles corresponding to each of the preset discharge voltages includes:

[0154] The battery is charged and discharged multiple times according to the preset discharge voltage, and the battery performance parameters of the battery are obtained after each charge and discharge; wherein one preset discharge voltage corresponds to multiple battery performance parameters;

[0155] Based on the plurality of battery performance parameters corresponding to the preset discharge voltage, the available number of cycles corresponding to the preset discharge voltage is determined.

[0156] It should be noted that in order to obtain the preset number of available cycles corresponding to each preset discharge voltage, it is necessary to charge and discharge the battery multiple times according to each preset discharge voltage, and obtain the battery performance parameters of the battery after each charge and discharge, so as to judge the number of available cycles corresponding to each preset discharge voltage through the battery performance parameters.

[0157] Here, since different preset discharge voltages correspond to different preset available cycle times, the number of charge and discharge times of the battery is different according to each preset discharge voltage.

[0158] It can be understood that, since the battery is charged and discharged multiple times according to a preset discharge voltage, the battery performance parameters are obtained once after each charge and discharge cycle. Therefore, one preset discharge voltage corresponds to multiple battery performance parameters.

[0159] Here, battery performance parameters include but are not limited to rated voltage, rated capacity, and impedance, etc., which are not limited in the present disclosure.

[0160] It should be explained that after obtaining a plurality of battery performance parameters corresponding to each preset discharge voltage, the number of available cycles corresponding to the preset discharge voltage can be determined by observing changes in the battery performance parameters.

[0161] In the disclosed embodiment, the battery is first charged and discharged multiple times according to the preset discharge voltage to obtain battery performance parameters of the battery after each charge and discharge; then, based on the multiple battery performance parameters corresponding to the preset discharge voltage, the available number of cycles corresponding to the preset discharge voltage is determined, thereby being able to obtain an accurate number of available cycles, which is beneficial to improving the accuracy of the target number of cycles to meet the long life requirements of the battery.

[0162] In some embodiments, determining the number of available cycles corresponding to the preset discharge voltage based on the plurality of battery performance parameters corresponding to the preset discharge voltage includes:

[0163] Based on the number of the battery performance parameters that meet the preset conditions, the available number of cycles corresponding to the preset discharge voltage is determined.

[0164] It should be noted that in order to improve the accuracy of each preset number of available cycles, a preset condition can be set, so that when the battery is charged and discharged multiple times according to the preset discharge voltage, it is determined whether the battery performance parameters meet the preset conditions after each charge and discharge. When the battery performance parameters meet the preset conditions, the charge and discharge cycle is continued until the battery performance parameters fail to meet the preset conditions, so that the number of available cycles corresponding to the preset discharge voltage can be determined.

[0165] Therefore, the number of available cycles corresponding to the preset discharge voltage has a corresponding relationship with the number of battery performance parameters that meet the preset conditions.

[0166] Here, the battery performance parameter may be the capacity retention rate of the battery and the thickness expansion of the battery, and the preset condition may be that the capacity retention rate is within a first limit value range and the thickness expansion value is within a second limit value range.

[0167] Meanwhile, the first limit value and the second limit value may be set arbitrarily, and the embodiments of the present disclosure do not limit this.

[0168] It is understandable that the capacity retention rate and thickness expansion value are important indicators for measuring the service life of batteries. The capacity retention rate refers to the ratio of the capacity that can be maintained by the battery after a period of use to the initial capacity. The higher the capacity retention rate, the better the stability of the battery. The thickness expansion value refers to the change in thickness when the battery expands, which can reflect the changes in the internal voltage, temperature, etc. of the battery. The higher the thickness expansion value, the more likely it is to affect the safety and reliability of the battery, which will shorten the service life of the battery.

[0169] Exemplarily, the preset condition is set to a value between capacity retention rate ≥ 80% and thickness expansion ≤ 8% to 20%. When the battery is charged and discharged multiple times according to the preset discharge voltage, the capacity retention rate and thickness expansion value after each charge and discharge are compared with the preset conditions to determine whether the battery performance parameters meet the preset conditions and further determine the preset number of available cycles corresponding to the preset discharge voltage.

[0170] The embodiment of the present disclosure determines the preset number of available cycles corresponding to the preset discharge voltage based on the number of the battery performance parameters that meet the preset conditions, thereby facilitating the improvement of the accuracy of each preset number of available cycles and laying a foundation for optimizing the battery charge and discharge strategy.

[0171] In some embodiments, the method further comprises:

[0172] The preset voltage threshold is determined from each of the preset discharge voltages based on the historical performance parameters of the battery.

[0173] It is understandable that, in addition to determining the preset voltage threshold value based on the user's usage habits, the preset voltage threshold value can also be determined from each of the preset discharge voltages based on historical performance parameters of the battery.

[0174] Here, according to different preset discharge voltages, during the charge and discharge test of the battery, by judging the historical performance parameter changes of the battery at each preset voltage, the preset voltage corresponding to the smallest historical performance parameter change of the battery can be selected as the preset voltage threshold.

[0175] For example, during a charge and discharge test of a battery, when the preset discharge voltage is 3.5V, the available number of cycles of the battery is large, and the historical performance parameters of the battery vary little, then 3.5V may be determined as the preset voltage threshold.

[0176] In the disclosed embodiment, based on the historical performance parameters of the battery, the preset voltage threshold is determined from each of the preset discharge voltages. Thus, by setting a preset discharge voltage that is beneficial to the health of the battery as the preset voltage threshold, it is helpful to optimize the battery's charge and discharge strategy, thereby ensuring that the battery has a large discharge capacity while also meeting the battery's long battery life requirements.

[0177] In some embodiments, when the number of cycles of controlling the charge and discharge of the battery based on the first discharge cut-off voltage reaches the target number of cycles corresponding to the first discharge cut-off voltage, controlling the charge and discharge of the battery based on the second discharge cut-off voltage includes:

[0178] When the number of charge and discharge cycles of the battery controlled based on the first discharge cut-off voltage reaches a target number of cycles corresponding to the first discharge cut-off voltage, the second discharge cut-off voltage is obtained based on a second preset amplitude and the first discharge cut-off voltage, and the charge and discharge of the battery is controlled based on the second discharge cut-off voltage.

[0179] It should be noted that in order to reduce the situation where the battery discharge capacity drops rapidly due to a sudden rise in the discharge cut-off voltage, a second preset amplitude can be set in advance. When the number of charge and discharge cycles of the battery reaches the target number of cycles corresponding to the first discharge cut-off voltage, the second discharge cut-off voltage is obtained according to the second preset amplitude and the first discharge cut-off voltage.

[0180] Here, the second preset amplitude may be the same as or different from the first preset amplitude, and this is not limited in the embodiment of the present disclosure.

[0181] For example, the second preset amplitude may be 0.1V, and the first discharge cut-off voltage may be 0.1V. 1 The first discharge cut-off voltage is 2.8V. 1The corresponding target cycle number is 160 times. When the battery is charged and discharged for 160 times, the first discharge cut-off voltage is increased by 0.1V. 1 , and obtain the second discharge cut-off voltage q 2 ,q 2 is 2.9V, and the battery is controlled to charge and discharge at 2.9V.

[0182] In the embodiment of the present disclosure, when the number of charge and discharge cycles of the battery controlled based on the first discharge cut-off voltage reaches the target number of cycles corresponding to the first discharge cut-off voltage, the second discharge cut-off voltage is obtained based on the second preset amplitude and the first discharge cut-off voltage, and the charge and discharge of the battery is controlled based on the second discharge cut-off voltage. In this way, the embodiment of the present disclosure can gradually increase the first discharge cut-off voltage according to the second preset amplitude to obtain the second discharge cut-off voltage, thereby avoiding the problem of rapid decrease in battery discharge capacity due to a sudden increase in discharge voltage, which is conducive to meeting the long battery life requirements of the battery.

[0183] In some embodiments, the method further comprises:

[0184] determining a first limit voltage within a preset adjustment range as the first discharge cut-off voltage; or

[0185] The first discharge cut-off voltage is determined based on the first limit voltage, the current cycle number of the battery, and a third preset amplitude.

[0186] It is understandable that since the entire life cycle of the battery is monitored, the first discharge cut-off voltage needs to be flexibly adjusted. In the disclosed embodiment, the first discharge cut-off voltage can be a first limit voltage within a preset adjustment range, or a discharge voltage determined based on the first limit voltage, the current number of cycles of the battery, and a third preset amplitude.

[0187] Here, the first preset amplitude, the second preset amplitude, and the third preset amplitude may be equal or unequal, and the embodiment of the present disclosure is not limited to this.

[0188] In some embodiments, when the preset adjustment range is 2.8V-3.8V, the second discharge cutoff can be 2.8V. When the first discharge voltage is less than the preset voltage threshold, the first discharge voltage is adjusted to 2.8V, and charging and discharging are performed at 2.8V.

[0189] In other embodiments, when the preset adjustment range is 2.8V-3.8V and the third preset amplitude is 0.1V, the second discharge cutoff is 2.9V. When the first discharge voltage is less than the preset voltage threshold, the first discharge voltage is adjusted to 2.9V, and charging and discharging are performed at 2.9V.

[0190] It should be noted that, when the first discharge cut-off voltage is determined based on the first limit voltage, the current cycle number of the battery and the third preset amplitude, the target cycle number corresponding to the first discharge cut-off voltage needs to be determined by the first preset adjustment coefficient, the target cycle number corresponding to the first limit voltage and the available cycle number corresponding to the second discharge voltage.

[0191] Exemplarily, the calculation formula for the target number of cycles corresponding to the first discharge cut-off voltage may be as follows:

[0192] n 2 =k 2 ×(yy 2 -n 1 ) (2)

[0193] In formula (2), n 2 represents the target number of cycles corresponding to the first discharge cut-off voltage, k 2 Indicates the first preset adjustment coefficient, yy 2 Indicates the number of available cycles corresponding to the first discharge cut-off voltage, n 1 Indicates the target number of cycles corresponding to the first limit voltage.

[0194] For example, setting k 2 is 0.8, the first discharge cut-off voltage q 2 When it is 2.9V, the first discharge cut-off voltage q is determined 2 The corresponding number of available cycles yy 2 The target number of cycles corresponding to the first limit voltage is 160 times. Based on formula (2), it can be calculated that the first discharge cut-off voltage q 2 The corresponding target number of cycles n 2 It is 112 times.

[0195] When the number of charge and discharge cycles of the battery reaches 112 times, based on the third preset amplitude of 0.1V, the first discharge cut-off voltage is increased again to obtain the second discharge cut-off voltage q 3 is 3.0V, and the second discharge cut-off voltage q is determined 3 The corresponding number of available cycles yy 3 is 400 times. Based on the above formula (2), it can be calculated that the second discharge cut-off voltage q 3 The corresponding target number of cycles n 3 It is 229 times.

[0196] In the embodiment of the present disclosure, the first limit voltage within the preset adjustment range can be determined as the first discharge cut-off voltage; the first discharge cut-off voltage can also be determined based on the first limit voltage, the current number of cycles of the battery and the third preset amplitude, so that the first discharge cut-off voltage can be flexibly adjusted by monitoring the user's usage habits, thereby ensuring that the large capacity benefit of the silicon material is maximized while meeting the long cycle requirements of the battery.
