Description

Technical Field

[0001] This disclosure relates to the field of battery processing, and more particularly to a battery processing method, apparatus, electronic device, storage medium, and computer program product. Background Technology

[0002] Currently, different manufacturers have different charging modes for their batteries, but battery charging modes can be divided into fast charging mode and slow charging mode. Fast charging mode aims to improve charging speed, while slow charging mode aims to ensure charging safety.

[0003] However, different users use batteries differently, which can lead to different levels of battery aging. If a single charging mode is used, such as controlling the battery to charge in fast charging mode to a set cutoff current, there may be a problem of battery charging capacity loss, which may result in the battery not being able to be fully charged.

[0004] Combining fast charging and slow charging modes can improve the problem of the battery not being able to fully charge, but it increases the charging time and cannot meet users' long battery life needs, which is not conducive to improving the user experience. Summary of the Invention

[0079] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0080] In this embodiment of the present disclosure, when the number of charge-discharge cycles of the battery enters the first range, the battery is controlled to charge to the first cutoff current according to the first charging mode, and the battery is controlled to continue charging to the second cutoff current according to the second charging mode; then the first charging capacity of the battery when it is charged to the second cutoff current according to the second charging mode is obtained; and when the number of charge-discharge cycles enters the second range, a third cutoff current is determined based on the first charging capacity and the first cutoff current, and the battery is controlled to charge according to the third cutoff current in the first charging mode.

[0081] Firstly, as the battery ages, its polarization resistance increases. Compared to charging the battery with a fixed third cutoff current, which leads to increased charging capacity loss in the first charging mode, the third cutoff current in this embodiment is dynamically adjusted based on the first charging capacity and the first cutoff current. This allows the adjusted third cutoff current to mitigate the impact of the battery's polarization resistance, thereby reducing charging capacity loss and ensuring the battery's range.

[0083] Thirdly, since users use batteries differently, the aging degree of the batteries varies. Therefore, in this embodiment, the third cutoff current is related to the first charging capacity, and the first charging capacity is related to the aging degree of the battery. This makes the third cutoff current match the user's usage habits, thereby ensuring the charging health of the battery to a greater extent, extending the battery's service life, and meeting the long-range battery needs of different users.

[0084] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0092] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0093] Figure 1 This is a flowchart illustrating 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:

[0094] In step 101, when the number of charge-discharge cycles of the battery enters the range of the first number, the battery is controlled to charge to the first cutoff current according to the first charging mode, and the battery is controlled to continue charging to the second cutoff current according to the second charging mode; wherein, the charging speed of the battery charging according to the second charging mode is lower than the charging speed of the battery charging according to the first charging mode.

[0095] In step 102, the first charging capacity of the battery when it is charged to the second cutoff current according to the second charging mode is obtained;

[0096] In step 103, when the number of charge-discharge cycles enters the range of the second number, a third cutoff current is determined based on the first charging capacity and the first cutoff current, and the battery is controlled to charge according to the third cutoff current in the first charging mode.

[0097] In this case, the number of cycles in the second range is greater than the number of cycles in the first range.

[0098] It should be noted that the battery processing method proposed in this disclosure can be applied to electronic devices. Here, electronic devices can include terminal devices, such as mobile terminals or fixed terminals. Mobile terminals can include devices such as mobile phones, tablets, laptops, and wearable electronic devices. Fixed terminals can include desktop computers, smart TVs, and in-vehicle devices. In some other embodiments, the battery processing method can also be applied to applications installed on electronic devices.

[0099] In other embodiments, the battery processing method of this disclosure can be configured in a battery processing device, which can be located in an electronic device; this disclosure does not limit this. It should be noted that the execution entity of this disclosure can be a central processing unit (CPU) in the electronic device in hardware, and related background services in the electronic device in software; this is not limited.

[0100] Understandably, the number of charge-discharge cycles is an important indicator for assessing battery aging and lifespan. As the number of charge-discharge cycles increases, internal chemical and physical changes occur within the battery, leading to a gradual decrease in capacity and impacting performance. Therefore, it's beneficial to obtain the number of charge-discharge cycles before charging to assess battery aging and determine the optimal charging method.

[0101] In some embodiments, the fuel gauge in the electronic device can accumulate the number of charge-discharge cycles (i.e., CycleCount) of the battery. Before the battery is charged, the number of charge-discharge cycles of the battery can be obtained based on the fuel gauge.

[0102] In some embodiments, in order to replenish more energy to the battery in a shorter time and meet the fast charging needs of modern life, the battery can be controlled to charge in a first charging mode with a higher charging speed. By increasing the charging current and charging voltage, the charging efficiency can be improved, thereby shortening the charging time of the battery.

[0103] It should be noted that although the charging time of the battery can be shortened by increasing the charging voltage and charging current in the first charging mode, excessive charging current can damage the battery. Therefore, in this embodiment of the present disclosure, setting a first cutoff current corresponding to the first charging mode can extend the battery's service life while ensuring the battery's charging efficiency.

[0104] Here, the process of charging the battery to the first cutoff current according to the first charging mode is as follows: When the battery voltage is below a certain threshold, trickle charging will first occur. The charging current in this stage is small and is used to restore the battery voltage and activate the internal chemical reactions of the battery. When the battery voltage rises to the trickle charging threshold, the charging current can be increased to perform constant current charging. In this stage, the charging current remains constant while the battery voltage gradually increases. When the battery voltage rises to the constant voltage charging threshold, the constant voltage charging stage ends, and the constant voltage charging stage can begin. In this stage, the charging voltage remains constant while the charging current gradually decreases until the charging current decreases to the first cutoff current.

[0105] In some embodiments, as the battery ages, the amount of active material inside the battery decreases, and the electrolyte concentration decreases, leading to an increase in the battery's polarization resistance. Here, the battery's polarization resistance is a phenomenon where the electrode potential deviates from its equilibrium value due to factors such as chemical reactions on the electrode surface and uneven charge distribution. During battery charging, the polarization resistance dissipates some electrical energy, thereby reducing the battery's charging efficiency and potentially reducing its charging capacity.

[0106] During battery charging, a larger charging current exacerbates chemical reactions and uneven charge distribution on the electrode surface. This leads to increased polarization resistance and consequently, increased energy loss, i.e., capacity loss. Conversely, a smaller charging current promotes more uniform chemical reactions and charge distribution on the electrode surface, thus reducing polarization resistance and minimizing energy loss, thereby mitigating the capacity loss problem.

[0107] Therefore, in this embodiment of the present disclosure, when the number of charge-discharge cycles of the battery enters the range of the first number, the battery is controlled to charge to the first cutoff current in the first charging mode with a higher charging speed, and the battery is controlled to continue charging to the second cutoff current in the second charging mode with a lower charging speed, so that the charging capacity obtained by the battery in the second charging mode can compensate for the charging capacity lost by the battery in the first charging mode, thereby satisfying the user's long battery life experience.

[0108] Here, the range of the first count can be set arbitrarily according to the requirements. For example, the range of the first count can be 90-100 times or 101-200 times. This embodiment of the present disclosure does not limit this.

[0109] In some embodiments, since the first charging mode can provide a larger charging current to the battery to shorten the charging time, the first cutoff current corresponding to the first charging mode is usually set to be relatively small to avoid overcharging. Conversely, since the second charging mode can provide a smaller charging current to the battery for safe charging, the second cutoff current corresponding to the second charging mode is usually set to be relatively large to improve charging efficiency.

[0110] In some embodiments, the battery cutoff current is preset and fixed throughout the battery's entire lifespan, regardless of whether it is the first charging mode or the second charging mode. However, due to differences in how users use the battery, the degree of battery aging varies. If the battery is charged according to the preset cutoff current, the battery may terminate charging prematurely, resulting in a decrease in the battery's charging capacity and a situation where the battery is not fully charged, thus reducing the battery's range.

[0111] Therefore, in this embodiment, a second range is defined, and the number of cycles in each range is greater than the number of cycles in the first range. When the battery's charge-discharge cycle count moves from the first range into the second range, it can be determined that the battery's aging degree may be deepening. To ensure the battery's long-lasting battery life, it is necessary to further determine the cutoff current for charging the battery within the second cycle range.

[0112] Here, since users have a need to shorten the charging time, the main purpose of this embodiment is to calibrate the cutoff current of the battery when charging in the first charging mode, so as to control the battery to charge to the calibrated cutoff current in the first charging mode, thereby improving the charging efficiency of the battery and achieving the purpose of fast charging.

[0113] It should be noted that since the first charging capacity of the battery when it is charged to the second cutoff current in the second charging mode can reflect the charging capacity lost by the battery in the first charging mode, and the lost charging capacity is related to the user's battery usage habits, the third cutoff current determined based on the first charging capacity and the first cutoff current can ensure the charging health of the battery while meeting the long-range battery life needs of different users.

[0114] Here, the first and second number ranges are two consecutive ranges of repetitions. The number of repetitions in each cycle within the first range can be the same as or different from the number of repetitions in each cycle within the second range. For example, if the first range is 91-100 times, then the second range is 101-200 times; if the first range is 501-600 times, then the second range is 601-700 times.

[0115] In some embodiments, if the first number of cycles is 1-100, it can be determined that the first number of cycles is the first 100-cycle range of the battery's charge-discharge cycle. In this case, the first cutoff current corresponding to the first charging mode is an initial value, where the initial value is the cutoff current value set at the factory based on the battery's own parameters (e.g., battery specifications, battery type, etc.). If the first number of cycles is 301-400, it can be determined that the first number of cycles is the third 100-cycle range of the battery's charge-discharge cycle. In this case, the first cutoff current corresponding to the first charging mode is not an initial value, but is determined based on the cutoff current corresponding to the first charging mode in the previous number range (i.e., the 201-300 cycle range) and the first charging capacity obtained by the battery in the second charging mode.

[0116] Understandably, once the battery's charge-discharge cycle count enters the second range, determining the third cutoff current allows the battery to be controlled to charge according to the third cutoff current in the first charging mode. This ensures the battery's charging capacity while shortening the charging time and improving the user experience.

[0117] In this embodiment of the present disclosure, when the number of charge-discharge cycles of the battery enters the first range, the battery is controlled to charge to the first cutoff current according to the first charging mode, and the battery is controlled to continue charging to the second cutoff current according to the second charging mode; then the first charging capacity of the battery when it is charged to the second cutoff current according to the second charging mode is obtained; and when the number of charge-discharge cycles enters the second range, a third cutoff current is determined based on the first charging capacity and the first cutoff current, and the battery is controlled to charge according to the third cutoff current in the first charging mode.

[0118] Firstly, as the battery ages, its polarization resistance increases. Compared to charging the battery with a fixed third cutoff current, which leads to increased charging capacity loss in the first charging mode, the third cutoff current in this embodiment is dynamically adjusted based on the first charging capacity and the first cutoff current. This allows the adjusted third cutoff current to mitigate the impact of the battery's polarization resistance, thereby reducing charging capacity loss and ensuring the battery's range.

[0119] Secondly, after determining the third cutoff current, the battery can be controlled to charge according to the third cutoff current in the first charging mode, thereby optimizing the charging efficiency of the battery and shortening the charging time of the battery to meet the user's fast charging needs.

[0120] Thirdly, since users use batteries differently, the aging degree of the batteries varies. Therefore, in this embodiment, the third cutoff current is related to the first charging capacity, and the first charging capacity is related to the aging degree of the battery. This makes the third cutoff current match the user's usage habits, thereby ensuring the charging health of the battery to a greater extent, extending the battery's service life, and meeting the long-range battery needs of different users.

[0121] In some embodiments, the method further includes:

[0122] When the number of charge-discharge cycles enters the first interval of the first number range, the battery is controlled to charge to the first cutoff current according to the first charging mode;

[0123] When the battery's charge-discharge cycle count enters the first range, the battery is controlled to charge according to the first charging mode to the first cutoff current, and then the battery is controlled to continue charging according to the second charging mode to the second cutoff current, including:

[0124] When the number of charge-discharge cycles enters the second range of the first number range, the battery is controlled to charge to the first cutoff current according to the first charging mode, and the battery is controlled to continue charging to the second cutoff current according to the second charging mode.

[0125] In this case, the number of cycles in each interval is greater than the number of cycles in each interval.

[0126] It should be noted that, in order to improve the user experience, the first count range includes a first interval and a second interval. The number of cycles in the second interval is greater than the number of cycles in the first interval. When the number of charge-discharge cycles of the battery is in the first interval of the first count range, it can be determined that the battery is less aged. Then, the battery can be controlled to charge according to the first charging mode to the first cutoff current, thereby ensuring the charging efficiency of the battery and shortening the charging time.

[0127] When the battery's charge-discharge cycle count falls within the second range of the second number range, it can be determined that the battery's aging has deepened. If the battery is only controlled to charge in the first charging mode, due to the increased polarization resistance, the battery may lose some charging capacity, resulting in the battery not being fully charged. Therefore, in this embodiment, the battery can be controlled to charge in the first charging mode to the first cutoff current, and then controlled to continue charging in the second charging mode to the second cutoff current. This allows the charging capacity acquired by the battery in the second charging mode to compensate for the charging capacity lost in the first charging mode, thereby satisfying the user's long-range driving experience. At the same time, it lays the foundation for calculating the third cutoff current within the second number range.

[0128] Here, the first interval of the first count range and the second interval of the first count range are consecutive within the first count range. For example, if the first count range is 1-100, then the first interval can be 1-90 and the second interval can be 91-100; or the first interval can be 1-93 and the second interval can be 94-100.

[0129] In some embodiments, since the number of charge-discharge cycles of the battery is within the second range of the first number range, the main purpose is to obtain the first charging capacity of the battery when it is charged to the second cutoff current in the second charging mode. If the charging stop operation is detected before the charging current reaches the second cutoff current during this process, the obtained charging capacity is invalid. Therefore, in order to ensure that the first charging capacity is obtained, the second range can be set to be relatively large, for example, the first number range is 301-400 cycles, and the second range can be 391-400 cycles.

[0130] For example, the first range of the first charge / discharge cycle count can be 1-90 cycles, and the second range can be 91-100 cycles. When the battery's charge / discharge cycle count is between 1-90 cycles, the battery is charged using a first charging mode with a higher charging speed to improve charging efficiency and shorten charging time. When the battery's charge / discharge cycle count is between 91-100 cycles, a combination of the first and second charging modes is used to charge the battery to ensure sufficient charging capacity, thereby meeting the user's need for a long battery life.

[0131] In this embodiment, the first charge / discharge cycle range includes a first interval and a second interval. The number of cycles in each interval of the second interval is greater than the number of cycles in each interval of the first interval. By distinguishing the interval in which the battery's charge / discharge cycle count falls, different charging schemes are used to charge the battery. When the charge / discharge cycle count enters the first interval, the battery is controlled to charge according to the first charging mode to the first cutoff current. Thus, in the early to mid-stages of charging within the first cycle range, the battery is charged only using the first charging mode with its higher charging speed, effectively shortening the charging time and ensuring a fast-charging experience throughout the battery's lifespan. When the charge / discharge cycle count enters the second interval, the battery is controlled to charge according to the first charging mode to the first cutoff current, and then continues to charge according to the second charging mode to the second cutoff current. Thus, in the later stages of charging within the first cycle range, the battery is charged using a combination of the first and second charging modes. This allows the charging capacity acquired by the battery in the second charging mode to compensate for the charging capacity lost due to battery polarization in the first charging mode, thereby helping to ensure a long battery life experience for the user.

[0132] In some embodiments, when the number of charge-discharge cycles enters the range of a second charge-discharge cycle, determining a third cutoff current based on a first charging capacity and a first cutoff current includes:

[0133] When the number of charge-discharge cycles enters the first interval of the second number range, the battery is controlled to charge according to the first charging mode to the first cutoff current, and then the battery is controlled to continue charging according to the first charging mode until the battery's charging capacity reaches the first charging capacity.

[0134] The current at which the charging capacity reaches the first charging capacity is determined as the third cutoff current.

[0135] It needs to be explained that, in order to meet users' fast charging needs, when the battery's charge-discharge cycle count enters the first interval of the second range, it is necessary to control the battery to charge according to the first charging mode until the first cutoff current. However, as the number of charge-discharge cycles increases and the battery ages further, the loss of charging capacity will increase when the battery is charged to the first cutoff current. Therefore, after controlling the battery to charge according to the first charging mode to the first cutoff current, it is possible to continue charging the battery to determine the third cutoff current.

[0136] Here, the first interval of the second number range can be set arbitrarily according to the requirements. For example, when the second number range is 401-500 times, the first interval of the second number range can be 401-490 times. This embodiment of the present disclosure does not limit this.

[0137] It is understandable that, since the first charging capacity can compensate for the charging capacity lost by the battery in the first charging mode to ensure the battery's range, in this embodiment of the present disclosure, the battery is first controlled to charge to the first cutoff current in the first charging mode, and then the battery is controlled to continue charging in the first charging mode until the battery's charging capacity reaches the first charging capacity, so as to determine the current when the battery obtains the first charging capacity in the first charging mode, and this current is determined as the third cutoff current. When charging with the third cutoff current, the problem that the battery cannot be fully charged due to the battery's polarization internal resistance can be improved.

[0138] In some embodiments, when the number of charge-discharge cycles of the battery enters the first interval of the second range, after controlling the battery to charge to the first cutoff current according to the first charging mode, the coulomb integration function of the fuel gauge can be triggered. When the charging capacity calculated by the fuel gauge reaches the first charging capacity, the current at this moment is obtained and the current at this moment is determined as the third cutoff current.

[0139] In this embodiment of the disclosure, when the number of charge-discharge cycles of the battery enters the first interval of the second range, the battery is controlled to charge in the first charging mode until the first cutoff current is reached, and then the battery is controlled to continue charging in the first charging mode until the battery's charging capacity reaches the first charging capacity, so as to obtain the current when the charging capacity reaches the first charging capacity. Thus, on the one hand, since the third cutoff current is the current obtained by controlling the battery to continue charging in the first charging mode until the charging capacity reaches the first charging capacity after the charging current reaches the first cutoff current, the third cutoff current can improve the problem of battery charging capacity loss caused by the increase of battery polarization internal resistance; on the other hand, after determining the third cutoff current, the battery can be controlled to charge in the first charging mode until the third cutoff current, thereby shortening the charging time while ensuring that the battery obtains sufficient charging capacity, thus ensuring the battery's long-range capability.

[0140] In some embodiments, controlling the battery to charge according to a third cutoff current in a first charging mode includes:

[0141] When the number of charge-discharge cycles enters the second interval of the second number range, the battery is controlled to charge in the first charging mode to the third cutoff current, and the battery is controlled to continue charging in the second charging mode to the second cutoff current.

[0142] It is understandable that when a battery's charge-discharge cycle count enters the second range of the second charge-discharge cycle count, it indicates that the battery is aging more significantly, leading to increased internal polarization resistance and greater capacity loss in the first charging mode, thus preventing the battery from fully charging. Therefore, a combined charging mode approach can be used to charge the battery. In the second charging mode, a smaller charging current is used to reduce the battery's internal polarization resistance, thereby mitigating capacity loss and ensuring a longer battery life for users.

[0143] Here, the second interval of the second number range and the first interval of the second number range are continuous in the second number range. For example, the first interval of the second number range is 301-390, and the second interval of the second number range is 391-400.

[0144] In this embodiment, when the battery's charge-discharge cycle count enters the second interval of the second range, the battery is first controlled to charge in the first charging mode to the third cutoff current, and then the battery is controlled to continue charging in the second charging mode to the second cutoff current. Thus, in the later stages of battery charging within the second range, the battery is charged using a combination of the first and second charging modes. This allows the charging capacity acquired by the battery in the second charging mode to compensate for the charging capacity lost due to battery polarization in the first charging mode, thereby helping to ensure a longer battery life experience for the user.

[0145] In some embodiments, obtaining the first charging capacity of the battery when it is charged to a second cutoff current in a second charging mode includes:

[0146] The charging time taken for the battery to be charged to the second cutoff current in the second charging mode, and the charging current at each moment within the charging time are obtained.

[0147] The first charging capacity is determined based on the charging time and charging current.

[0148] In some embodiments, the first charging capacity can be calculated by a fuel gauge. When the number of charge-discharge cycles of the battery enters the first range, the battery is first controlled to charge to the first cutoff current in the first charging mode, and then switched to the second charging mode to charge the battery. At this time, the coulomb integration function of the fuel gauge can be triggered. The fuel gauge can obtain the charging time used when the battery is charged to the second cutoff current in the second charging mode, as well as the charging current at each time. Then, based on the charging time and the charging current, the first charging capacity is calculated.

[0149] In this embodiment of the present disclosure, the charging time used by the battery to charge to the second cutoff current in the second charging mode and the charging current at each moment within the charging time are first obtained. Then, based on the charging time and the charging current, the first charging capacity is determined, which helps to improve the accuracy of determining the first charging capacity and lays the foundation for determining the third cutoff current.

[0150] In some embodiments, the method further includes:

[0151] Determine the battery temperature;

[0152] When the number of charge-discharge cycles enters the second range, based on the first charging capacity and the first cutoff current, a third cutoff current is determined, and the battery is controlled to charge according to the third cutoff current in the first charging mode, including:

[0153] When the battery temperature is within the first temperature range and the number of charge-discharge cycles enters the second range, the third cutoff current is determined based on the first charging capacity and the first cutoff current.

[0154] Within the first temperature range, the battery is controlled to charge according to the third cutoff current in the first charging mode.

[0155] It should be noted that during battery charging, if the battery temperature exceeds a certain range, excessive heat can cause overheating, leading to an excessively rapid electrochemical reaction rate within the battery. This can damage the internal structure and severely impact battery life. Conversely, if the battery temperature falls below a certain range, the low temperature can reduce the activity of the electrolyte, increasing internal resistance and reducing charging efficiency. Therefore, in this embodiment, a first temperature range is set, and after acquiring the battery temperature, it is determined whether the current battery temperature will affect the charging process.

[0156] Here, the first temperature range is the temperature range that has a relatively small impact on the battery charging process. It can be set according to requirements. For example, the first temperature range can be 15 degrees to 35 degrees. This embodiment of the present disclosure does not limit this.

[0157] In some embodiments, the battery has a built-in temperature sensor that can monitor the battery temperature in real time, thereby allowing the battery temperature to be determined in real time.

[0158] Understandably, when the battery temperature is within the first temperature range, it can be determined that the current battery temperature is unlikely to affect the battery charging process, which can reduce the error in calculating the third cutoff current, thus helping to obtain an accurate third cutoff current.

[0159] Here, after determining the third cutoff current, within the first temperature range, the battery can be controlled to charge according to the third cutoff current in the first charging mode, so as to shorten the charging time of the battery.

[0160] In this embodiment, since battery temperature affects the battery charging process, the battery temperature can be obtained first. Then, when the battery temperature is within a first temperature range and the battery's charge-discharge cycle count is within a second range, a third cutoff current is determined based on the first charging capacity and the first cutoff current. Finally, within the first temperature range, the battery is controlled to charge according to the third cutoff current in the first charging mode. This avoids the battery temperature affecting the calculation of the third cutoff current, thus facilitating the acquisition of an accurate third cutoff current and improving the reliability of the calibrated third cutoff current.

[0161] In some embodiments, the method further includes:

[0162] If the battery temperature exceeds the first temperature range, determine the current second temperature range of the battery and the fourth cutoff current preset for the second temperature range; wherein the preset cutoff current is different for different temperature ranges.

[0163] The fifth cutoff current is determined based on the third and fourth cutoff currents;

[0164] Within the second temperature range, the battery is controlled to charge at the fifth cutoff current in the first charging mode.

[0165] It is understandable that when the battery temperature changes and exceeds the first temperature range, in order to ensure the charging safety of the battery, the current second temperature range of the battery can be determined first, and then the cut-off current of the battery in the first charging mode can be redefined within the second temperature range.

[0166] In some embodiments, multiple temperature ranges can be preset, and after determining the battery temperature, the battery temperature is compared with each temperature value in each temperature range to determine the second temperature range in which the battery temperature is located.

[0167] Here, each temperature value in the second temperature range can be greater than each temperature value in the first temperature range, or it can be less than each temperature value in the first temperature range. This embodiment of the present disclosure does not limit this.

[0168] It should be noted that the degree of influence of battery temperature on the battery charging process varies in different temperature ranges. In order to adapt to the aging of the battery and ensure the charging safety of the battery, a fifth cutoff current for charging the battery in the first charging mode in the second charging range can be determined based on the fourth and third cutoff currents preset in the second temperature range.

[0169] Here, the preset cutoff current varies for different temperature ranges. In some embodiments, the preset cutoff current for each temperature range can be determined based on experience or experiments. For example, the preset cutoff current for the temperature range of -10 degrees to 15 degrees is I. 0_1F The preset cutoff current for the temperature range of 15 degrees to 35 degrees is I. 0_2F The preset cutoff current for the temperature range of 35 degrees to 48 degrees is I. 0_3F The preset cutoff current is I for a temperature range of -10 degrees to 15 degrees. 0_4F .

[0170] In some embodiments, since the fifth cutoff current is a cutoff current calibrated to compensate for the charging capacity lost by the battery in the first charging mode, the fifth cutoff current should be set to be relatively small. After determining the fourth cutoff current, the third cutoff current can be compared with the fourth cutoff current, and the smaller of the third and fourth cutoff currents can be determined as the fifth cutoff current.

[0171] In other embodiments, within the first temperature range, the third cutoff current is determined by the first charging capacity and the first cutoff current. The ratio of the third cutoff current to the first cutoff current can be calculated, and the ratio can be used as an adjustment coefficient to adjust the fourth cutoff current. The adjusted fourth cutoff current is then determined as the fifth cutoff current.

[0172] Understandably, after determining the fifth cutoff current, within the second temperature range, the battery is controlled to charge according to the fifth cutoff current in the first charging mode in order to improve the charging efficiency of the battery and shorten the charging time of the battery.

[0173] In this embodiment, if the battery temperature changes and exceeds a first temperature range, a second temperature range is determined, along with a preset fourth cutoff current for that range. A fifth cutoff current is then determined based on the third and fourth cutoff currents. Within the second temperature range, the battery is controlled to charge according to the fifth cutoff current in the first charging mode. Thus, by determining the battery temperature change, first identifying the second temperature range and the fourth cutoff current, and then determining the cutoff current for charging in the first charging mode within the second temperature range, an accurate fifth cutoff current can be obtained, ensuring the battery's charging capacity within the second temperature range and ultimately satisfying the user's need for a long battery life.

[0174] In some embodiments, determining the fifth cutoff current based on the third cutoff current and the fourth cutoff current includes:

[0175] When the third cutoff current is less than the fourth cutoff current, the fifth cutoff current is determined based on the ratio of the first and third cutoff currents and the fourth cutoff current; wherein the ratio of the fourth and fifth cutoff currents is the same as the ratio of the first and third cutoff currents; or,

[0176] If the third cutoff current is greater than the fourth cutoff current, the fifth cutoff current is determined based on the ratio of the first cutoff current to the third cutoff current and the fourth cutoff current, or the fourth cutoff current is determined as the fifth cutoff current.

[0177] Understandably, since the fifth cutoff current is calibrated to compensate for the charging capacity lost by the battery in the first charging mode, it should be set relatively small. To improve the accuracy of determining the fifth cutoff current, the third and fourth cutoff currents can be compared, and the fifth cutoff current can be determined accordingly based on the comparison results.

[0178] Here, if the third cutoff current is less than the fourth cutoff current, the smaller of the two cutoff currents is determined as the third cutoff current. However, the third cutoff current corresponds to the cutoff current within the first temperature range. If the battery is charged to the third cutoff current according to the first charging mode, it can be assumed that the battery will be in a depleted state, meaning it will lose some charging capacity. To ensure the battery is used without loss, the ratio of the first cutoff current to the third cutoff current can be calculated. Based on this ratio, the fourth cutoff current can be adjusted proportionally to obtain the fifth cutoff current.

[0179] For example, if the third cutoff current is I n_2F Then the first cutoff current is expressed as I. n-1_2FThe ratio of the first cutoff current to the third cutoff current is expressed as: If the fourth cutoff current I n-1_3F Then the fifth cutoff current is expressed as

[0180] Here, if the third cutoff current is greater than the fourth cutoff current, the smaller of the two cutoff currents is determined as the fourth cutoff current. Since the fourth cutoff current is a preset cutoff current for the second temperature range, it can be used as the fifth cutoff current to quickly determine it. Alternatively, to improve the accuracy of determining the fifth cutoff current, the ratio of the first to the third cutoff current can be calculated, and the fourth cutoff current can be adjusted proportionally according to this ratio to obtain the fifth cutoff current.

[0181] In this embodiment, the ratio of the first cutoff current to the third cutoff current can be calculated first, and the fifth cutoff current can be determined based on the ratio and the fourth cutoff current. Alternatively, the fourth cutoff current can be determined as the fifth cutoff current, thus providing multiple ways to determine the fifth cutoff current and laying the foundation for determining the fifth cutoff current in different temperature ranges.

[0182] In some embodiments, when the third cutoff current is greater than the fourth cutoff current, determining the fifth cutoff current based on the ratio of the first cutoff current to the third cutoff current and the fourth cutoff current, or determining the fourth cutoff current as the fifth cutoff current, includes:

[0183] When the third cutoff current is greater than the fourth cutoff current, and all temperature values ​​in the second temperature range are greater than all temperature values ​​in the first temperature range, the fifth cutoff current is determined based on the ratio of the first cutoff current to the third cutoff current and the fourth cutoff current.

[0184] If the third cutoff current is greater than the fourth cutoff current, and all temperature values ​​in the second temperature range are less than all temperature values ​​in the first temperature range, then the fourth cutoff current is determined as the fifth cutoff current.

[0185] It should be noted that, in order to obtain an accurate fifth cutoff current when the third cutoff current is greater than the fourth cutoff current, the temperature values ​​in the second temperature range can be compared with the temperature values ​​in the first temperature range first. Based on the comparison results, the method for determining the fifth cutoff current can be obtained.

[0186] Specifically, if all temperature values ​​in the second temperature range are greater than all temperature values ​​in the first temperature range, it can be determined that the battery is in a high-temperature charging process. The ratio of the first cutoff current to the third cutoff current can be calculated, and the fourth cutoff current can be adjusted proportionally based on the ratio to obtain the fifth cutoff current.

[0187] For example, the ratio of the first cutoff current to the third cutoff current is expressed as: If the fourth cutoff current is I n-1_1F Then the fifth cutoff current is expressed as If the fourth cutoff current is I n-1_3F Then the fifth cutoff current is expressed as The fourth cutoff current is I n-1_4F Then the fifth cutoff current is expressed as

[0188] If all temperature values ​​in the second temperature range are lower than all temperature values ​​in the first temperature range, it can be determined that the battery is in a low-temperature charging process. Considering the protection of battery performance by low-temperature charging, it is considered that there is no need to adjust the low-temperature charging. The fourth cutoff current preset for the second temperature range can be used. Therefore, the fourth cutoff current is determined as the fifth cutoff current.

[0189] For example, if the fourth cutoff current is I n-1_1F Then the fifth cutoff current can be expressed as I n_1F =I n-1_1F .

[0190] In this embodiment, when the third cutoff current is greater than the fourth cutoff current, the temperature values ​​within the second temperature range are first compared with the temperature values ​​within the first temperature range to obtain a comparison result. Then, based on the comparison result, a method for determining the fifth cutoff current is obtained. Since the method for determining the fifth cutoff current is related to the temperature values ​​within the second temperature range, an accurate fifth cutoff current can be obtained according to the battery parameters. This optimizes the battery's charging efficiency while ensuring charging safety and extending the battery's lifespan.

[0195] In step 204, the first charging capacity of the battery when it is charged to the second cutoff current according to the second charging mode is obtained.

[0196] In step 205, when the number of charge-discharge cycles of the battery enters the first interval of the second number range, the battery is controlled to charge according to the first charging mode to the first cutoff current, and then the battery is controlled to continue charging according to the first charging mode until the battery's charging capacity reaches the first charging capacity.

[0197] In step 206, the current at which the charging capacity reaches the first charging capacity is determined as the third cutoff current.

[0200] In step 301, the current second temperature range of the battery temperature and the fourth cutoff current preset for the second temperature range are determined.

[0201] In some embodiments, the battery temperature is determined; when the battery temperature is within a first temperature range and the number of charge-discharge cycles of the battery enters a second range, a third cutoff current is determined based on a first charging capacity and a first cutoff current; and within the first temperature range, the battery is controlled to charge in a first charging mode according to the third cutoff current.

[0202] In other embodiments, when a change in battery temperature is detected and the battery temperature exceeds a first temperature range, a second temperature range in which the battery temperature is currently located is determined, and a fourth cutoff current preset for the second temperature range is determined; wherein the preset cutoff current is different for different temperature ranges.

[0203] In step 302, it is determined whether the third cutoff current is greater than the fourth cutoff current.

[0204] In step 303, if the third cutoff current is greater than the fourth cutoff current, the fifth cutoff current is determined based on the ratio of the first cutoff current to the third cutoff current and the fourth cutoff current, or the fourth cutoff current is determined as the fifth cutoff current.

[0205] In some embodiments, when the third cutoff current is greater than the fourth cutoff current and each temperature value in the second temperature range is greater than each temperature value in the first temperature range, the fifth cutoff current is determined based on the ratio of the first cutoff current to the third cutoff current and the fourth cutoff current.

[0206] In other embodiments, when the third cutoff current is greater than the fourth cutoff current and all temperature values ​​in the second temperature range are less than all temperature values ​​in the first temperature range, the fourth cutoff current is determined as the fifth cutoff current.

[0207] In step 304, if the third cutoff current is less than the fourth cutoff current, the fifth cutoff current is determined based on the ratio of the first cutoff current to the third cutoff current and the fourth cutoff current.

[0208] In step 305, within the second temperature range, the battery is controlled to charge according to the fifth cutoff current in the first charging mode.
