Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a charging method, apparatus, device, and computer-readable storage medium. Background Technology

[0002] With the development of fast charging technology for mobile devices, battery charging power is constantly increasing. High-power battery charging solutions can significantly shorten battery charging time, allowing the battery to gain more power in a short period of time. However, higher power means faster charging speed, which also places higher demands on battery life and the hardware of the mobile device.

[0003] The relevant technologies only balance charging speed and battery life based on short-term individual information such as the battery health and temperature of the user terminal, without taking into account the different charging needs of different users, and without providing a universal standard solution. Summary of the Invention

[0004] To overcome the problems existing in the related technologies, this disclosure provides a charging method, apparatus, device, and computer-readable storage medium that can solve the above-mentioned problems.

[0005] According to a first aspect of the present disclosure, a charging method is provided, the method comprising: receiving a first charging parameter sent by a server, the first charging parameter being determined at least based on a battery change trend; determining a second charging parameter based on user usage habits; determining a target charging parameter based on the first charging parameter and the second charging parameter; and charging based on the target charging parameter.

[0006] According to a second aspect of the present disclosure, a charging method is provided, the method comprising: acquiring change trend information of a plurality of batteries; determining a first charging parameter based at least on the change trend information; and sending the first charging parameter to a terminal, so that the terminal determines a target charging parameter based on the first charging parameter and a second charging parameter and performs charging based on the target charging parameter, wherein the second charging parameter is determined by the terminal according to user usage habits.

[0007] According to a third aspect of the present disclosure, a charging device is provided, the device comprising: a receiving unit configured to receive first charging parameters sent by a server, the first charging parameters being determined at least based on a battery change trend; a processing unit configured to determine second charging parameters based on user usage habits; and to determine target charging parameters based on the first charging parameters and the second charging parameters; and a charging unit configured to charge based on the target charging parameters.

[0008] According to a fourth aspect of the present disclosure, a charging device is provided, the device comprising: an acquisition unit configured to acquire change trend information of a plurality of batteries; a processing unit configured to determine a first charging parameter based at least on the change trend information; and a sending unit configured to send the first charging parameter to a terminal, so that the terminal determines a target charging parameter based on the first charging parameter and a second charging parameter and performs charging based on the target charging parameter, wherein the second charging parameter is determined by the terminal according to user usage habits.

[0009] According to a fifth aspect of the present disclosure, an electronic device is provided, comprising: a processor and a memory; the memory being used to store a computer program; and the processor being used to execute the charging method as described in the first and second aspects by invoking the computer program.

[0010] According to a sixth aspect of the present disclosure, a computer-readable storage medium is provided having a computer program stored thereon that, when executed by a processor, implements the charging method as described in the first and second aspects.

[0011] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0012] The charging method proposed in this disclosure allows a user terminal to choose between a first charging parameter and a second charging parameter. The first charging parameter is determined by a server based on battery change trend information from sample terminals, while the second charging parameter is determined by the user terminal based on user usage and charging habits. The first charging parameter is a unified strategy determined by the server using big data algorithms, while the second charging parameter incorporates the user terminal's charging habits, reflecting the user's charging habits and needs. Therefore, based on embodiments of this disclosure, when a user terminal selects a charging parameter from the first and second options to charge the battery, it can balance charging speed and battery life while conforming to the user's charging habits.

[0021] 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.

These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0024] To address the aforementioned technical problems, this disclosure proposes a charging method.

[0025] Figure 1 This is a system architecture diagram illustrating a charging method according to an embodiment of the present disclosure.

[0026] like Figure 1 As shown, user terminal 110 can communicate and interact with server 120.

[0027] Server 120 can collect data from the sample terminal, determine the first charging parameters based on the collected data, and then send them to user terminal 110.

[0028] In some embodiments, the server may also include a cloud server.

[0029] The server can be called a cloud-controlled configuration platform.

[0030] It should be noted that the user terminal 110 may be any of the sample terminals, or it may not be a sample terminal. The user terminal is the terminal used to execute the charging method proposed in this disclosure; the sample terminal is the terminal used to provide the server with information on the battery's changing trends, that is, the terminal for the server to obtain data information.

[0031] Figure 2 This is a schematic flowchart illustrating a charging method according to an embodiment of the present disclosure. The charging method can be executed by a user terminal 110. The user terminal 110 can use charging parameters determined by the charging method and charge the battery in the user terminal based on the determined charging parameters. The user terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and Internet of Things devices.

[0032] like Figure 2 As shown, the charging method includes:

[0033] In step S201, the first charging parameter sent by the server is received, and the first charging parameter is determined based at least on the battery's changing trend;

[0034] In step S202, the second charging parameters are determined based on the user's usage habits;

[0035] In step S203, the target charging parameters are determined based on the first charging parameters and the second charging parameters;

[0036] In step S204, charging is performed based on the target charging parameters.

[0037] In some embodiments, a first charging parameter is received from a server, the first charging parameter being determined by the server based at least on information about the battery change trend of the sample terminal.

[0038] The specific method by which the server determines the first charging parameter will be described in detail in the method embodiments on the server side, and will not be elaborated here.

[0039] Battery trend information can reflect the changing trends of the battery. For example, the aging trend of the battery or the trend of battery life degradation.

[0040] Based on the battery change trends of the sample terminals, the server can provide user terminals with relatively reliable first charging parameters as a reference, so as to avoid poor changes in the user terminal's battery and slow down the battery life degradation.

[0041] In some embodiments, the sample terminal may be a terminal of the same type as the user terminal.

[0042] For example, the sample terminal could be a terminal with the same battery model, or a terminal from the same manufacturer and of the same brand. The closer the sample terminal is to the user terminal, the greater the reference value of its battery change trend information, and the more effectively the server-determined initial charging parameters can mitigate the potentially adverse battery change trends faced by the user terminal.

[0043] In some embodiments, the sample terminal may include a user terminal.

[0044] The server can also obtain information on the battery change trends of user terminals, and determine the first charging parameters based on the change trend information of all sample terminals obtained through an algorithm.

[0045] User terminals can also be sample terminals. After determining the first charging parameters, the server can send the first charging parameters to the user terminals. In some embodiments, the server can send the first charging parameters to all sample terminals.

[0046] In some embodiments, the number of sample terminals is at least multiple.

[0047] The first charging parameter is determined by the server based on the battery change trend information of multiple sample terminals. With the support of a large amount of data, the first charging parameter can accurately solve or alleviate the battery life problem faced by most terminals.

[0048] In some embodiments, the second charging parameters are determined based on user habits.

[0049] Different users have different habits when using a device. These differences in usage habits can be reflected in the device's charging habits parameters. For example, the duration of charging, the number of times a day to charge, and the time of day to charge.

[0050] Charging habit parameters reflect users' personalized needs. Therefore, the second charging parameter determined based on charging habit parameters can better match the user's actual usage scenario and balance charging speed and battery life. For example, if the charging duration is long (charging continuously from nighttime until dawn), the charging current can be further reduced to delay the time when the user's device is fully charged (in this scenario, it is only necessary to ensure that the device reaches full charge before dawn, without needing to charge too quickly). This avoids overcharging and recharging caused by discharging after full charge, thereby extending battery life without affecting user experience.

[0051] In some embodiments, target charging parameters are determined based on the first charging parameters and the second charging parameters.

[0052] The server instructs the user terminal to provide the first charging parameters. The user terminal determines the second charging parameters based on its own algorithm and user habits. Based on the first and second charging parameters, the target charging parameters are determined.

[0053] After determining the target charging parameters, the user terminal can charge the battery in the user terminal based on the target charging parameters.

[0054] In some embodiments, determining the target charging parameters based on the first charging parameters and the second charging parameters includes: performing a weighted summation of the first charging parameters and the second charging parameters to determine the charging parameters adopted by the user terminal.

[0055] The weights of the first and second charging parameters can be adjusted. For example, if the user terminal obtains comprehensive, reliable, and accurate charging habit parameters, the weight of the second charging parameter should be greater; if the user's charging behavior is highly random and not fixed, the user terminal obtains fewer charging habit parameters, and the weight of the first charging parameter can be increased.

[0056] Based on embodiments of this disclosure, the server determines a first charging parameter based on the battery change trend information of sample terminals, and the user terminal determines a second charging parameter based on charging habit parameters. The user terminal then determines the required charging parameters based on the first and second charging parameters. The server can determine charging parameters that effectively extend battery life based on the battery change trend information of a large number of sample terminals. The user terminal can also classify users based on charging habit parameters to determine their personalized needs. After receiving the first charging parameter, the user terminal can comprehensively consider the influence of both the first and second charging parameters to determine the required charging parameters, ensuring that the adopted charging parameters balance battery life and charging speed, and better meet the user's actual needs and usage habits.

[0057] In some embodiments, the charging parameters include at least one of the following: charging current; cutoff voltage; cutoff current; full charge capacity.

[0058] For example, the charging current includes the Fast Charging Current (FCC), which indicates the charging current used in fast charging mode. The larger the charging current, the faster the battery is fully charged and the faster the charging speed.

[0059] For example, the cutoff current includes the charging cutoff current (Iterm). During the charging process, when the charging current drops to this cutoff current, the battery can be considered fully charged, thus stopping the charging process and avoiding overcharging.

[0060] For example, the cutoff voltage includes the maximum full charge voltage (FV), which indicates the maximum full charge voltage that the battery can reach. When the battery voltage reaches this voltage, charging of the battery is stopped.

[0061] For example, the full charge capacity, the maximum capacity of the battery when fully charged, can be limited so that the battery only charges a portion of its capacity each time, instead of fully charging. For instance, if the battery's maximum capacity is 100%, and the full charge capacity is controlled to 80%, the battery will display "fully charged" when it reaches 80% and will stop charging, which helps extend battery life.

[0062] It should be noted that the first charging parameter and the second charging parameter may contain the same charging habit parameter or different charging habit parameter; if they contain the same charging habit parameter, the charging habit parameter adopted by the user terminal shall be determined based on the same charging habit parameter.

[0063] For example, if the first charging parameter includes a first charging current and the second charging parameter includes a second charging current, then the charging current used by the user terminal needs to be determined based on the first charging current and the second charging current; and if the first charging parameter includes a first full charge capacity and the second charging parameter does not include a full charge capacity charging habit parameter, then the charging habit parameter used by the user terminal is the value indicated by the first charging parameter or the second charging parameter that includes the charging habit parameter.

[0064] In some embodiments, the user usage habits include at least one of the following charging habit parameters: the battery level range of the user terminal when charging begins; the charging frequency of the user terminal; the charging period of the user terminal; the ambient temperature range where the user terminal is charging; the charging location of the user terminal; the climate of the region where the user terminal is located; the power range of the charger connected to the user terminal; the duration of user use of the user terminal; and the duration of continuous charging of the user terminal.

[0065] Based on the charging habit parameters, users can be categorized into charging priority users (charging at the fastest speed), battery protectors (maximizing battery life), and intelligent charging balance users (balancing charging speed and battery life).

[0066] In some embodiments, user types can be divided into 15 levels. The higher the level, the greater the need for extended battery life, and correspondingly, a lower charging current can be used to extend battery life.

[0067] The lower the level, the higher the user's demand for fast charging, and a higher charging current should be used to meet the user's fast charging needs.

[0068] The user terminal can detect the user's charging habits and / or charging behavior to derive the aforementioned charging habit parameters.

[0069] For example, the terminal can detect the battery level range of the user terminal when charging begins, which may include three ranges: 0-30% is the low battery range, 30%-80% is the medium battery range, and 80-100% is the high battery range.

[0070] For example, the terminal can detect the charging frequency, which may include once a day, twice a day, three times a day or more.

[0071] For example, the terminal can detect charging times, including charging at night and midday (preferring slow charging to protect battery life), charging in the morning and afternoon (preferring fast charging), and charging at non-specific times (preferring to balance charging speed and battery life).

[0072] For example, the ambient temperature range in which the user terminal is charged may include high temperature (30°C and above), low temperature (15°C and below), and room temperature (15°C-30°C);

[0073] For example, the charging location of the user terminal includes outdoor charging and indoor charging;

[0074] For example, the climate of the region where the user terminal is located includes cold (latitude greater than or equal to 50 degrees), warm (latitude greater than 25 degrees and less than 50 degrees), and hot (latitude less than or equal to 25 degrees).

[0075] For example, the power range of the charger connected to the user terminal includes a slow charger (low power), a constant speed charger (medium power), and a fast charger (high power).

[0076] For example, the duration of a user's use of the user terminal includes light use (less than 2 hours per day), moderate use (2-4 hours per day), and heavy use (more than 4 hours per day).

[0077] For example, the duration of continuous charging of the user terminal includes temporary charging (less than 15 minutes), short-term charging (15-30 minutes), long-term charging (30-60 minutes), and continuous charging (more than 60 minutes).

[0078] In some embodiments, the corresponding values ​​of the charging habit parameters can be determined.

[0079] When there is more than one charging habit parameter, each parameter can be assigned a value to facilitate calculation. For example, when the battery level range at the start of charging is detected, a value can be assigned to the detected range. One feasible example is to divide the battery level range from 0-100% into four different intervals and assign them values ​​of 0, 1 / 3, 2 / 3, and 1 respectively. These values ​​can then be used in subsequent calculations to represent the user terminal's score on that charging habit parameter.

[0080] In some embodiments, determining the second charging parameter based on user habits includes: performing a weighted summation on at least one charging habit parameter to determine a first reference value; determining a first product of the first reference value and a first parameter step size for each type of charging parameter; and determining the difference between a preset charging parameter and the corresponding first product as the second charging parameter.

[0081] When charging habit parameters include multiple sub-parameters, these sub-parameters can be weighted and summed to determine a first reference value. This first reference value can then be converted into a user level to determine the degree to which the user's terminal needs to adjust its charging parameters.

[0082] For example, as an example, the charging habit parameter may include multiple charging habit sub-parameters mentioned in the above embodiments, then:

[0083] First reference value = (Battery level of the user terminal at the start of charging * 15%) + (Charging frequency of the user terminal * 20%) + (Charging period of the user terminal * 10%) + (Ambient temperature range of the user terminal during charging * 10%) + (Charging location of the user terminal * 10%) + (Duration of user use of the user terminal * 20%) + (Continuous charging duration of the user terminal * 15%).

[0084] In some embodiments, since each charging habit sub-parameter is assigned a value of 0-1, the determined first reference value is greater than or equal to 0 and less than or equal to 1. This first reference value can be used to determine the second charging parameter. However, since the value is small, it is difficult to reflect the difference in the second charging parameter caused by different charging habit parameters of the user terminal. Therefore, the first reference value can be amplified by the number of user levels.

[0085] In some embodiments, after determining the first reference value, the first reference value can be multiplied by the number of user levels to determine the level of the user terminal. For example, when the user level is divided into 15 levels, the first reference value is multiplied by 15 to appropriately amplify the first reference value.

[0086] In some embodiments, a first product of the first reference value and a first parameter step size of various charging parameters is determined.

[0087] Since charging parameters may include various types, such as charging current, cutoff voltage, and cutoff current, the corresponding first parameter step size also corresponds to different types of charging parameters. The first parameter step size corresponding to the charging current can be different from the first parameter step size corresponding to the cutoff voltage. When determining the first product, the type of charging parameter needs to correspond to the first parameter step size.

[0088] In some embodiments, the first product of the amplified first reference value and the first parameter step size may also be included.

[0089] In some embodiments, the difference between a preset charging parameter and a corresponding first product is determined as the second charging parameter.

[0090] The formula for the second charging parameter is: Second charging parameter = Preset charging parameter - First reference value * First parameter step size.

[0091] Specifically, the second charging parameters include: charging current FCC = preset charging current - first reference value * FCC step size; maximum full charge voltage FV = preset maximum full charge voltage - first reference value * FV step size; and charging cut-off current iterm = preset charging cut-off current - first reference value * iterm step size.

[0092] As can be seen from the above formula, the larger the first reference value and the smaller the second charging parameter, the slower the charging speed of the user terminal, but the longer the battery life.

[0093] In some embodiments, the first reference value determined by the user terminal based on charging habit parameters differs in different charging environments, and the corresponding second charging parameters differ as well.

[0094] The first reference value and the second charging parameter can change in real time. For example, if the same user terminal is connected to the charger around 8 a.m., based on charging habits, it can be determined that this is a morning rush charge, with a short charging duration. The user needs to increase the battery capacity as much as possible in a short time. In this case, the determined first reference value is smaller, and the second charging parameter is larger, so that the user terminal can maintain a high-current fast charge. However, if the user terminal is connected to the charger after midnight, based on charging habits, it can be determined that this is a continuous overnight charge, with a longer duration. In this case, the first reference value is larger, and the second charging parameter is smaller. The user terminal uses a low-current slow charge to extend the battery life.

[0095] In some embodiments, determining the target charging parameter based on the first charging parameter and the second charging parameter includes: when the first charging parameter and the second charging parameter include the same type of charging parameter, determining the parameter of the same type of charging parameter that is relatively smaller among the first charging parameter and the second charging parameter as the target charging parameter.

[0096] For example, if the first charging parameters sent by the server include charging current and cutoff voltage, and the second charging parameters determined by the user terminal also include charging current, cutoff voltage, and cutoff current, then the first and second charging parameters include the same type of charging parameters (charging current and cutoff voltage). The smaller value of the charging current provided by the first and second charging parameters can be selected as the charging current in the target charging parameters; the smaller value of the cutoff voltage provided by the first and second charging parameters can be selected as the cutoff voltage in the target charging parameters.

[0097] The first charging parameter is a reference parameter given by the server based on the sample terminal. If the second charging parameter determined by the user terminal is smaller, the second charging parameter will be used. This charging parameter has a better effect on extending battery life and is more in line with the user's usage habits. If the second charging parameter determined by the user terminal is larger, the first charging parameter can be used to achieve a balance between basic charging speed and battery life.

[0098] In some embodiments, determining the target charging parameter based on the first charging parameter and the second charging parameter includes: when the first charging parameter and the second charging parameter are of different types, determining the first charging parameter and the second charging parameter of different types as the target charging parameter.

[0099] For example, the type of the first charging parameter may be different from the type of the second charging parameter, so the different types of the first and second charging parameters can be used as the target charging parameters respectively.

[0100] For example, if the first charging parameter gives the charging current and the second charging parameter gives the cutoff voltage, and the first and second charging parameters give different parameter types but do not give different values ​​for the same type of parameter, then when the terminal is charging, the charging current uses the value indicated by the first charging parameter and the cutoff voltage uses the value indicated by the second charging parameter.

[0101] In contrast to the charging method on the user terminal side described above, this disclosure also proposes a charging method executed on the server side.

[0102] Figure 3 This is a schematic flowchart illustrating a charging method according to an embodiment of the present disclosure. The charging method can be executed by a server 120. The server 120 can obtain information on the battery change trend of a sample terminal and provide the user terminal 110 with first charging parameters for selection.

[0103] like Figure 3 As shown, in some embodiments, the method includes:

[0104] In step S301, the changing trend information of multiple batteries is obtained;

[0105] In step S302, at least the first charging parameter is determined based on the change trend information;

[0106] In step S303, the first charging parameter is sent to the terminal so that the terminal determines the target charging parameter based on the first charging parameter and the second charging parameter and performs charging based on the target charging parameter, wherein the second charging parameter is determined by the terminal according to the user's usage habits.

[0107] In some embodiments, the server can obtain battery change trend information from multiple sample terminals.

[0108] The number of sample terminals is not limited to one. Sample terminals can also be all terminals of the same model. All terminals can upload their own battery change trend information for the server to obtain, and the server can use this information to determine suitable initial charging parameters based on an algorithm.

[0109] The server can obtain battery trend information from sample terminals through a big data tracking platform. Sample terminals can periodically send (a process called "tracking") battery trend information to the platform.

[0110] For example, the data source could be an OMS (Order Management System) data warehouse, feedback data, logs, or after-sales FFR (First Fix Rate) data.

[0111] In some embodiments, the battery trend information includes at least one of the following: the decrease in the remaining battery capacity per unit time; the decrease in battery health per unit time; and the decrease in the full charge voltage of the battery per unit time.

[0112] As batteries are used, their remaining capacity gradually decreases. Therefore, the remaining capacity can reflect battery life to some extent; the decrease in remaining capacity per unit time reflects the rate of battery degradation. Similarly, battery health is affected by multiple factors (such as internal resistance, rated voltage, bulging, and the degree of lithium crystallization), and can comprehensively reflect the changes in battery state and performance compared to its original state and performance. Full charge voltage is the maximum voltage a battery can reach when fully charged.

[0113] For the above parameters, the greater the decrease per unit time, the greater the battery life degradation. The battery change trend information can reflect the general battery health of the sample terminals. The first charging parameter determined by the algorithm based on the battery change trend information of multiple sample terminals can meet the balance requirements of charging speed and battery life under normal conditions.

[0114] In some embodiments, a first charging parameter is determined at least based on the change trend information.

[0115] The trend information reflects that the faster the battery life degrades, the smaller the first charging parameter, thereby slowing down the charging speed and extending the battery life.

[0116] In some embodiments, the first charging parameter, determined based on trend information, can be determined by a model. The model can be based on machine learning or deep learning.

[0117] Based on a big data analytics platform, user feedback on charging and discharging of various types of sample terminals can be obtained as input, including rankings, quality aspects, baseband performance, and software problem analysis. This data can then be used to adjust the algorithm model and determine the optimal algorithm model.

[0118] The input to this algorithm model can be battery trend information and / or charging habit parameters, and the output is charging parameters.

[0119] In some embodiments, the first charging parameter is sent to the user terminal, wherein the first charging parameter is used by the user terminal to determine the charging parameter to be used among the first charging parameter and the second charging parameter, and the second charging parameter is determined by the user terminal according to the user terminal's charging habit parameters.

[0120] After obtaining information on battery change trends from multiple sample terminals and a more refined algorithm model, the server can determine more suitable first charging parameters and directly send the determined first charging parameters to the user terminal.

[0121] Compared to updating the charging algorithm on the server side, where the user terminal downloads the updated charging algorithm via OTA (Over-The-Air) technology and then determines the charging parameters, the embodiments disclosed in this paper can reduce maintenance and optimization costs, as well as release costs, and provide users with the best experience in a timely manner.

[0122] In some embodiments, the method further includes: obtaining user satisfaction with the charging speed of the plurality of sample terminals; wherein, determining the first charging parameter based at least on the trend information includes: determining the first charging parameter based on the trend information and the user satisfaction with the charging speed.

[0123] User satisfaction with the charging speed can be periodically assessed. Low user satisfaction indicates a low charging current from the server, resulting in slow charging. In this case, the charging current needs to be increased to accelerate charging and improve user satisfaction. Conversely, high user satisfaction indicates a fast charging speed, with no user complaints about slowness. Therefore, the server can adjust the charging current from the first charging parameter to appropriately reduce the charging current from the user terminal, thereby extending battery life.

[0124] Therefore, on the server side, in addition to battery trend information affecting the first charging parameter, user satisfaction with the charging speed can also influence it. The first charging parameter needs to be determined based on both the trend information and user satisfaction with the charging speed.

[0125] In some embodiments, determining the first charging parameter based at least on the trend information includes: weighting and summing the trend information and / or the user's satisfaction with the charging speed to determine a second reference value; determining a second product of the second reference value and the second parameter step size of various charging parameters; and determining the difference between historical charging parameters and the corresponding second product as the first charging parameter.

[0126] It should be noted that historical charging parameters can be any time before the currently determined charging parameters, for example, the most recent time, i.e., the previous time.

[0127] The second reference value can be determined by weighted summation of trend information and / or user satisfaction with charging speed. For ease of calculation, the trend information and user satisfaction with charging speed can be normalized, and the processed values ​​can then be weighted and summed.

[0128] For example, when the trend information includes the battery remaining capacity trend, battery health trend, and maximum full charge voltage trend, the formula for the second reference value can be:

[0129] Second reference value = Remaining capacity trend value * 30% + Battery health trend value * 40% + Full charge voltage trend value * 20% + Satisfaction with charging speed value * 10%.

[0130] After determining the second reference value, the second product of the second reference value and the second parameter step size of various charging parameters can be determined; and the difference between the historical charging parameters and the corresponding second product can be determined as the first charging parameter.

[0131] In some embodiments, the first charging parameters sent by the server to the user terminal may include at least one of the following: charging current, charging cut-off current, and maximum charging voltage.

[0132] It should be noted that the charging current indicated by the server can be the upper limit of the charging current of the user terminal's battery, and this upper limit charging current is related to the user's satisfaction with the charging speed.

[0133] Charging cutoff current = historical cutoff current - second reference value * cutoff current step size.

[0134] Maximum charging voltage = historical maximum voltage - second reference value * charging voltage step size.

[0135] In some embodiments, the second reference value can be positive or negative. The absolute value of the second reference value is greater than or equal to 0 and less than or equal to 1.

[0136] When the second reference value is positive, the value of the first charging parameter is smaller than the value of the historical charging parameter.

[0137] In some embodiments, the first charging parameter may further include: maximum capacity at full charge.

[0138] In practice, the maximum full-charge capacity of the user's battery can be left unrestricted to allow for longer battery life. However, in some cases, the maximum full-charge capacity of the user's terminal can be limited by the first charging parameter. The actual maximum battery capacity is 100%, but the first charging parameter causes the battery to display as fully charged when it reaches 95%. This has a smaller impact on the actual user experience, but it can effectively prevent overcharging and improve battery life.
