[0074] 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.

[0075] 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:

[0076] In step 101, when a charge and discharge event is detected, the current aging degree and current charge and discharge current of the battery are determined;

[0077] In step 102, a target charge and discharge current is determined based on the current charge and discharge current and the current aging degree;

[0078] In step 103, the battery is charged and discharged according to the target charge and discharge current.

[0079] 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.

[0080] 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.

[0081] It should be noted that overcharging and overdischarging will aggravate the aging of the battery and also affect the charging and discharging capacity of the battery. In order to meet the user's demand for long battery life, for aged batteries, it is necessary to adjust the charging and discharging current of the battery to improve the charging and discharging capacity of the battery.

[0082] It should be explained that different target charge and discharge currents need to be determined for batteries with different aging degrees. Therefore, in the embodiment of the present disclosure, when a charge and discharge event is detected, it is necessary to first determine the current aging degree and current charge and discharge current of the battery, and then further determine the target charge and discharge current corresponding to the battery based on the current charge and discharge current and the current aging degree.

[0083] It is understandable that the degree of battery aging is in a corresponding relationship with the performance of the battery. During the operation of the battery, the battery is monitored to obtain the performance parameters of the battery, wherein the performance parameters of the battery include at least one of the internal resistance of the battery, the number of charge and discharge cycles of the battery, or the full capacity of the battery. Based on the performance parameters of the battery, the state parameters of the battery can be determined, wherein the state parameters can characterize the aging parameters of the battery.

[0084] In some embodiments, during the charging and discharging process of the battery, the performance parameters of the battery can be obtained in real time or periodically to improve the timeliness and effectiveness of the obtained performance parameters of the battery. After obtaining the performance parameters, the current aging degree corresponding to the current performance parameters can be determined based on the target relationship between the battery performance parameters and the aging degree, thereby improving the accuracy of determining the current aging degree.

[0085] Here, the battery can be a power battery or an energy storage battery, which is not limited in the embodiments of the present disclosure.

[0086] It is understandable that the degree of battery aging can be expressed in the form of a ratio. For example, after the battery has been used for multiple times, the performance parameters of the battery have decreased. According to testing, the current battery has aged by 40% compared to the initial use.

[0087] It needs to be explained that the discharge capacity and charge capacity of the battery affect the service life of the battery. In actual use, the charge capacity of the battery can be improved based on different charging methods, but the means of controlling the discharge method of the battery are very limited, which is not conducive to improving the discharge capacity of the battery.

[0088] Here, the discharge mode of the battery includes but is not limited to controlling the discharge depth and reducing the discharge current, which is not limited in the embodiments of the present disclosure.

[0089] It should be noted that the depth of discharge (DOD) indicates the percentage of battery discharge to the rated capacity of the battery. The deeper the discharge depth, the more electricity the battery discharges, and the longer the battery can be used continuously on a single charge. However, the deeper the discharge depth, the shorter the battery life.

[0090] In order to balance the conflicting relationship between the battery life and the time the device can be continuously used after one charge, the related art usually sets a fixed shutdown threshold parameter based on human experience. As the battery gradually discharges, when the discharge meets the shutdown threshold parameter, the shutdown is initiated. In fact, the battery power is not completely discharged at this time, but some power is retained to prevent the battery from being discharged too deeply and causing the battery aging to increase. However, the accuracy of controlling the discharge depth of the battery based on the fixed shutdown threshold parameter set by human experience is low, so that the battery life is still not high.

[0091] In another related technology, by reducing the discharge rate, that is, discharging with a small current, more capacity can be released than discharging with a large current, which is beneficial to improving the discharge capacity of the battery. However, blindly reducing the discharge current value will lead to excessive discharge of the battery and shorten the charging cycle life.

[0092] Based on this, the embodiment of the present disclosure obtains the polarization degree of the battery by intelligently monitoring the aging degree of the battery, and further determines the target charge and discharge current of the battery, thereby improving the charging capacity and discharging capacity of the battery.

[0093] Specifically, when a charge and discharge event is detected, the current aging degree, current discharge current and current charging current of the battery are first determined; based on the current discharge current and the current aging degree, the target discharge current is determined; and based on the current charging current and the current aging degree, the target charging current is determined.

[0094] It is understandable that in order to meet the user's demand for long battery life, after determining the target charge and discharge current of the battery, it is necessary to adjust the current charge and discharge current of the battery, and charge and discharge the battery with the target charge and discharge current.

[0095] Here, the target charging current and the target discharging current of the battery may be the same or different, and the embodiment of the present disclosure is not limited to this.

[0096] In the embodiment of the present disclosure, when a charge and discharge event is detected, the current aging degree and current charge and discharge current of the battery are first determined; then based on the current charge and discharge current and the current aging degree, the target charge and discharge current is determined; finally, the battery is charged and discharged according to the target charge and discharge current. In this way, by monitoring the aging degree of the battery and dynamically adjusting the charge and discharge current according to the aging degree of the battery, the polarization phenomenon of the battery is weakened, thereby effectively improving the discharge capacity and charge capacity of the battery, avoiding damage to the battery due to over-discharge or over-charging, and helping to improve the user's long-range experience.

[0097] In some embodiments, Figure 2A schematic diagram of a battery processing method according to an exemplary embodiment Figure 2 ,like Figure 2 As shown, the determining the target charge and discharge current based on the current charge and discharge current and the current aging degree includes:

[0098] In step 201, a target adjustment coefficient is determined based on the current aging degree and a preset adjustment coefficient;

[0099] In step 202, the target charge and discharge current is determined based on the target adjustment coefficient and the current charge and discharge current.

[0100] It should be noted that, in order to improve the accuracy of determining the target charge and discharge current, a preset adjustment coefficient may be preset, and then the target adjustment coefficient of the target charge and discharge current may be determined based on the current aging degree and the preset adjustment coefficient.

[0101] Here, the preset adjustment coefficient can be set arbitrarily, and the embodiment of the present disclosure is not limited to this.

[0102] At the same time, the preset adjustment coefficient of the charging current and the preset adjustment coefficient of the discharging current may be the same or different, and the embodiments of the present disclosure are not limited to this.

[0103] Exemplarily, the preset adjustment coefficient may be a value less than or equal to 1, and the preset adjustment coefficient may be set to 0.8.

[0104] It is understandable that in order to increase the discharge capacity and charge capacity of the battery, the charge and discharge current needs to be adjusted. Therefore, after obtaining the target adjustment coefficient, the current charge and discharge current needs to be adjusted according to the target adjustment coefficient to obtain the target charge and discharge current.

[0105] In some embodiments, a target adjustment coefficient corresponding to a target charging current is first determined based on a current aging degree of the battery and a preset adjustment coefficient; and then the target charging current is determined based on the target adjustment coefficient and the current charging current.

[0106] In other embodiments, a target adjustment coefficient corresponding to a target discharge current is first determined based on the current aging degree of the battery and a preset adjustment coefficient; and then the target discharge current is determined based on the target adjustment coefficient and the current discharge current.

[0107] In the embodiment of the present disclosure, a target adjustment coefficient is determined based on the current aging degree and a preset adjustment coefficient; and the target charge and discharge current is determined based on the target adjustment coefficient and the current charge and discharge current. Thus, based on the current aging degree of the battery, the current charge and discharge current can be adjusted in real time, so that the polarization phenomenon of the battery is weakened, and the charging capacity and discharging capacity of the battery are improved.

[0108] In some embodiments, determining the target charge and discharge current based on the target adjustment coefficient and the current charge and discharge current includes:

[0109] The target charge and discharge current is determined based on the product of the target adjustment coefficient and the current charge and discharge current.

[0110] It should be noted that in order to improve the accuracy of calculating the target charge and discharge current, the target adjustment coefficient and the current charge and discharge current may be multiplied, and the calculated product may be determined as the target charge and discharge current.

[0111] Exemplarily, the target charge and discharge current may be calculated as follows:

[0112] I1=kI2 / (1+t) (1);

[0113] In formula (1), I1 represents the target charge and discharge current, I2 represents the current charge and discharge current, k / (1+t) represents the target adjustment coefficient, where k represents the preset adjustment coefficient, and t represents the current aging degree.

[0114] In the embodiment of the present disclosure, the target charge and discharge current is determined based on the product of the target adjustment coefficient and the current charge and discharge current, which is beneficial to improving the accuracy of obtaining the target charge and discharge current.

[0115] In some embodiments, the charge and discharge events include: discharge events, and the charge and discharge currents include: discharge currents;

[0116] The determining the target charge and discharge current based on the current charge and discharge current and the current aging degree includes:

[0117] Obtaining the current remaining power of the battery;

[0118] When the remaining power is within a preset range, a target discharge current is determined based on the current discharge current and the current aging degree.

[0119] It can be understood that the charge and discharge events of the battery may include a charge event and a discharge event, and the charge and discharge current of the battery may include a charge current and a discharge current.

[0120] It should be noted that in order to improve the accuracy of the battery discharge strategy, it is necessary to set a preset range corresponding to the remaining power of the battery. When the remaining power of the battery is within the preset range, the discharge strategy can be executed to avoid damage to the battery due to excessive discharge.

[0121] Here, the preset range can be set arbitrarily, and the embodiments of the present disclosure are not limited to this.

[0122] It should be explained that the discharge strategy is to adjust the discharge current of the battery. In order to effectively improve the discharge capacity of the battery, the target discharge current can be determined based on the current discharge current and the current aging degree of the battery. After determining the target discharge current, the battery needs to be discharged according to the target discharge current, so as to ensure that the aged battery can release more stored capacity.

[0123] Specifically, when the remaining power of the battery is within a preset range, the current aging degree of the battery and the current discharge current value are first determined; then, based on the current aging degree and the preset adjustment coefficient, the target adjustment coefficient of the discharge current is determined; finally, based on the product of the target adjustment coefficient and the current discharge current value, the target discharge current value is determined.

[0124] For example, the preset range is set to 1%-80%, and the preset adjustment coefficient is 0.8. If the current remaining power of the battery is 55%, it is determined that the current aging degree of the battery has increased by 50% and the current discharge current is 500mA, based on the above formula (1), the target discharge current can be calculated to be 267mA. After the current aging degree of the battery has increased by 75%, based on the above formula (1), the target discharge current can be calculated to be 229mA.

[0125] Therefore, in the embodiment of the present disclosure, the target discharge current is different for different current aging degrees of the battery. Thus, compared with continuously discharging the battery with the same target discharge current, the embodiment of the present disclosure adjusts the target discharge current in real time based on the change of the current aging degree of the battery, which is more conducive to improving the discharge capacity of the battery.

[0126] In the disclosed embodiment, when the charge and discharge event includes: a discharge event, and the charge and discharge current includes: a discharge current, the current remaining power of the battery is obtained; when the remaining power is within a preset range, a target discharge current is determined based on the current discharge current and the current aging degree, so that the battery can be discharged according to the target discharge current, so that the polarization phenomenon of the battery is weakened, which is beneficial to improving the discharge capacity of the battery, thereby ensuring that the aged battery can release more stored power capacity and avoiding damage to the battery due to excessive discharge.

[0127] In some embodiments, the charge and discharge events include: charging events, and the charge and discharge currents include: charging currents;

[0128] The determining the target charge and discharge current based on the current charge and discharge current and the current aging degree includes:

[0129] When the battery is in a constant voltage charging mode, a target charging current is determined based on a current charging current and the current aging degree.

[0130] It needs to be explained that the battery charging mode includes constant current charging mode and constant voltage charging mode. When the battery is in constant current charging mode, the battery voltage gradually rises until it reaches the charging cut-off voltage, but at this time there is a part of polarization voltage. If charging is stopped at this time, the battery will not be fully charged. In order to eliminate polarization, the charging current gradually decreases during constant voltage charging, which is the depolarization process. The smaller the discharge current in the final constant voltage charging stage, the higher the charging capacity.

[0131] Therefore, in order to improve the accuracy of the battery charging strategy, the charging strategy is executed only when the battery is in a constant voltage charging mode, thereby avoiding damage to the battery due to overcharging.

[0132] It is understandable that the charging strategy is to adjust the charging current of the battery. In order to effectively improve the charging capacity of the battery, the target charging current can be determined based on the current charging current and the current aging degree of the battery. After determining the target charging current, the battery is charged according to the target charging current, thereby ensuring that the aged battery can be charged with enough electricity to meet the user's long-term battery life requirements.

[0133] Specifically, when the battery is in constant voltage charging mode, the current aging degree of the battery and the current charging current value are first determined; then, based on the current aging degree and the preset adjustment coefficient, the target adjustment coefficient of the charging current is determined; finally, based on the product of the target adjustment coefficient and the current charging current value, the target charging current value is determined.

[0134] For example, the preset adjustment coefficient is 0.8. If the battery is in constant voltage charging mode, it is determined that the current aging degree of the battery has increased by 50% and the current charging current is 600mA. Based on the above formula (1), the target charging current can be calculated to be 320mA. When the current aging degree of the battery has increased by 80%, based on the above formula (1), the target charging current can be calculated to be 267mA.

[0135] In the embodiment of the present disclosure, if the charge and discharge event includes: a charging event, the charge and discharge current includes: a charging current; when the battery is in a constant voltage charging mode, a target charging current is determined based on the current charging current and the current degree of aging, so that the battery can be charged according to the target charging current, so that the polarization phenomenon of the battery is weakened, which is beneficial to improving the charging capacity of the battery, thereby ensuring that the aged battery can be charged with enough electricity to avoid damage to the battery due to overcharging.

[0136] 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, when a charge and discharge event is detected, determining the current aging degree of the battery includes:

[0137] In step 301, when the charge and discharge event is detected, the current number of charge and discharge cycles of the battery is obtained;

[0138] In step 302, a preset aging degree that matches the current number of cycles is determined as the current aging degree.

[0139] It should be noted that since the number of charge and discharge cycles of a battery is related to the degree of battery aging, in the embodiment of the present disclosure, when a battery charge and discharge event is detected, in order to determine the current degree of battery aging, it is necessary to first obtain the current number of charge and discharge cycles of the battery.

[0140] Here, the charge and discharge cycle of a battery refers to a period in which the battery is fully charged and then exhausted.

[0141] It is understandable that different charge and discharge cycle numbers correspond to different battery aging degrees. When the battery has fewer charge and discharge cycle numbers, the current aging degree of the battery is lower; when the battery has more charge and discharge cycle numbers, the current aging degree of the battery is higher.

[0142] It should be explained that in order to improve the accuracy of determining the current aging degree, it is necessary to determine a preset aging degree that matches the current number of cycles based on the acquired current number of cycles, and determine the preset aging degree as the current aging degree.

[0143] Exemplarily, when a charge and discharge event of a battery is detected, it is first determined that the current number of charge and discharge cycles of the battery is 100 times, and then the aging degree matching the cycle number of 100 is determined as the current aging degree of the battery.

[0144] In the embodiment of the present disclosure, when the charge and discharge event is detected, the current number of charge and discharge cycles of the battery is obtained; the preset aging degree that matches the current number of cycles is determined as the current aging degree, so that the aging degree of the battery can be monitored in real time, and a corresponding charge and discharge strategy can be formulated according to the aging degree to avoid damage to the battery due to overcharging or over-discharging.

[0145] In some embodiments, the method further comprises:

[0146] Obtaining voltage parameters of the battery after charging and discharging at different cycle times;

[0147] Determining a first voltage variation amplitude between each of the voltage parameters and a first standard voltage parameter;

[0148] Determining the preset aging degree corresponding to each of the number of cycles based on each of the first voltage change amplitudes;

[0149] A correlation relationship between the preset aging degree and each of the cycle numbers is established.

[0150] It should be explained that in order to improve the efficiency of determining the current aging degree, an association relationship between different cycle numbers and preset aging degrees can be established in advance. In this way, after obtaining the current cycle number of charging and discharging of the battery, the preset aging degree corresponding to the current cycle number can be determined based on the association relationship, and the preset aging degree is determined as the current aging degree.

[0151] It is understandable that in order to establish the correlation between different cycle numbers and the preset aging degree, it is necessary to perform multiple charge and discharge cycles on the battery and obtain various first voltage parameters of the battery after the battery is charged and discharged according to different cycle numbers. Based on the various first voltage parameters, the preset aging degree corresponding to the various voltage parameters is determined.

[0152] Here, the voltage parameter may be a voltage drop.

[0153] It should be noted that, in order to improve the stability of the determined voltage parameters, a time range may be preset, that is, the voltage parameters within a period of time when the battery is undergoing a charge and discharge cycle are obtained.

[0154] Here, the time range can be set arbitrarily, and the embodiments of the present disclosure are not limited to this.

[0155] Exemplarily, the time range is 10 seconds to 60 seconds. Within 10 seconds to 60 seconds after the battery is fully charged, the first voltage value is first measured; within 10 seconds to 60 seconds after the battery is exhausted, the second voltage value is measured, and based on the difference between the first voltage value and the second voltage value, the voltage drop of the battery for one charge and discharge cycle is determined.

[0156] It should be explained that in order to improve the accuracy of determining the preset aging degree, the first standard voltage parameter can be obtained first, and then the first voltage change amplitude between each voltage parameter and the first standard voltage parameter can be determined, and then based on each of the first voltage change amplitudes, the preset aging degree corresponding to each of the cycle numbers can be determined.

[0157] Here, the first standard voltage parameter may be a voltage parameter obtained when the battery performs a charge and discharge cycle for the first time, or may be a voltage parameter obtained when the battery performs a fixed number of charge and discharge cycles, which is not limited in the embodiments of the present disclosure.

[0158] Meanwhile, the fixed number of times may be set arbitrarily, and the embodiments of the present disclosure do not limit this.

[0159] It should be noted that the variation amplitude of the first voltage of the battery is positively correlated with the aging degree of the battery, that is, the larger the variation amplitude of the first voltage of the battery, the higher the aging degree of the battery; the smaller the variation amplitude of the first voltage of the battery, the lower the aging degree of the battery.

[0160] It is understandable that after obtaining each preset aging degree, it is necessary to establish a connection between each preset aging degree and the corresponding cycle number, so that after detecting the current cycle number of the battery, the preset aging degree corresponding to the current cycle number can be quickly located.

[0161] For example, the voltage of the battery drops by p millivolts after XX seconds after the battery is fully charged and exhausted, and after the battery is aged and subjected to XXX charge and discharge cycles, the voltage of the battery drops by q millivolts after XX seconds after the battery is fully charged and exhausted. The calculation formula for the degree of aging can be as follows:

[0162] t=(qp) / p (2);

[0163] In formula (2), t represents the aging degree, q represents the current voltage parameter, and p represents the standard voltage parameter.

[0164] In some embodiments, the battery is charged and discharged for 5 times, and the voltage parameters for 30 seconds after full charge and exhaustion are set as standard voltage parameters. The calculation process of the battery aging degree when the battery is charged and discharged for 200 times is specifically as follows:

[0165] After the battery has been charged and discharged for 5 times, the voltage parameter is 20 millivolts 30 seconds after it is fully charged and exhausted. After the battery has been charged and discharged for 200 times, the voltage parameter is 30 millivolts 30 seconds after it is fully charged and exhausted. Based on formula (2), it can be calculated that the battery has aged by 50%.

[0166] In the embodiment of the present disclosure, the voltage parameters of the battery after being charged and discharged according to different cycle numbers are obtained; and the voltage variation range between each of the first voltage parameters and the first standard voltage parameter is determined; based on each of the first voltage variation ranges, the preset aging degree corresponding to each of the cycle numbers is determined; and finally, the association relationship between the preset aging degree and each of the cycle numbers is established. In this way, in the embodiment of the present disclosure, since the association relationship between the preset aging degree and each of the cycle numbers can be established in advance, in the process of monitoring the aging degree of the battery, it is only necessary to determine the current cycle number of the battery being charged and discharged to determine the current aging degree of the battery.

[0167] In some embodiments, when a charge and discharge event is detected, determining the current aging degree of the battery further includes:

[0168] When the charge and discharge event is detected, determining in real time the voltage parameters of the battery after the charge and discharge;

[0169] Determining a second voltage variation amplitude between the voltage parameter and a second standard voltage parameter;

[0170] Based on the second voltage variation amplitude, a current aging degree of the battery is determined.

[0171] It should be noted that, in addition to determining the current aging degree of the battery by obtaining the current number of charge and discharge cycles of the battery in real time, the current aging degree of the battery can also be determined by obtaining the voltage parameters of the battery after charge and discharge in real time.

[0172] Therefore, when the charging and discharging events are detected, the embodiment of the present disclosure determines in real time the voltage parameters of the battery after charging and discharging, and compares the voltage parameters with the second standard voltage parameters, thereby determining the second voltage change amplitude of the battery, and then finally determines the current aging degree of the battery through the second voltage change amplitude.

[0173] It can be understood that the variation amplitude of the second voltage of the battery is positively correlated with the aging degree of the battery, that is, the larger the variation amplitude of the second voltage of the battery, the higher the aging degree of the battery; the smaller the variation amplitude of the second voltage of the battery, the lower the aging degree of the battery.

[0174] Here, the second standard voltage parameter may be a voltage parameter obtained when the battery performs a charge and discharge cycle for the first time, or may be a voltage parameter obtained when the battery performs a fixed number of charge and discharge cycles, which is not limited in the embodiments of the present disclosure.

[0175] Meanwhile, the second standard voltage parameter may be the same as or different from the first standard voltage parameter, and this is not limited in the embodiment of the present disclosure.

[0176] In some embodiments, a second standard voltage parameter may be preset, and after obtaining the voltage parameter of the battery after charging and discharging, the current aging degree of the battery may be calculated based on the above formula (2).

[0177] Exemplarily, the battery is charged and discharged for 5 times, and the voltage parameters for 30 seconds after full charge and exhaustion are set as standard voltage parameters. The calculation process of the battery aging degree when the battery is charged and discharged for 200 times is specifically as follows:

[0178] When the battery is charged and discharged for 5 times, the voltage parameter is 20 millivolts 30 seconds after being fully charged and exhausted; when the battery is charged and discharged for 200 times, the voltage parameter is 30 millivolts 30 seconds after being fully charged and exhausted; based on formula (2), it can be calculated that the battery has aged by 50%; if the battery is charged and discharged for 200 times, the voltage parameter is 35 millivolts 30 seconds after being fully charged and exhausted; based on formula (2), it can be calculated that the battery has aged by 75%.

[0179] In the embodiment of the present disclosure, when the charge and discharge event is detected, the voltage parameter of the battery after charge and discharge is first determined in real time; then the second voltage change amplitude between the voltage parameter and the second standard voltage parameter is determined; and finally, based on the second voltage change amplitude, the current aging degree of the battery is determined. Therefore, in the process of monitoring the aging degree of the battery, it is only necessary to determine the voltage parameter of the battery during charge and discharge to determine the current aging degree of the battery, which is conducive to simplifying the process of determining the aging degree of the battery.
