[0025] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that the terms "first," "second," and the like in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0027] Currently, different operating conditions have varying impacts on battery aging, and thus battery life. These include factors such as temperature and battery charge level. If a battery is exposed to high charge and high temperature for extended periods, its lifespan is significantly shortened, leading to poor battery efficiency.

[0028] Figure 1 This is a flow chart of a charging management method according to an embodiment of the present disclosure. It should be noted that the charging management method according to this embodiment can be applied to a charging management device, which can be configured in an electronic device or chip to enable the electronic device or chip to perform charging management functions.

[0029] Among them, the electronic device or chip equipped with the charging management device may be provided with a battery for managing the charging of the battery; or, the electronic device or chip equipped with the charging management device may be a charging device for charging the battery.

[0030] Among them, the electronic device can also be any device with computing capabilities, such as a personal computer (PC), a mobile terminal, a server, a controller in a vehicle, etc. The mobile terminal can be, for example, a vehicle-mounted device, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and other hardware devices with various operating systems, touch screens and / or display screens.

[0031] In addition, the charging management device can also be software in an electronic device, such as a battery management system. In the following embodiments, the execution subject is an electronic device as an example for description.

[0032] like Figure 1 As shown, the method includes the following steps:

[0033] Step 101 : Obtain battery parameter information of a target battery within a preset time period; the battery parameter information includes the temperature and remaining power percentage of the target battery at each time point within the preset time period.

[0034] In the embodiments of the present disclosure, the target battery may be a battery in an electronic device, or a battery in any device that communicates with the electronic device, or any battery that communicates with the electronic device. The battery may be, for example, an energy storage battery. An energy storage battery can store a large amount of electrical energy and quickly release it when needed to meet power demands.

[0035] Among them, energy storage batteries can be batteries in electronic products, electric vehicles and other products.

[0036] In the embodiment of the present disclosure, each time point in the preset time period may be a time point for collecting battery parameters of the target battery, wherein the battery parameters of the target battery may include temperature, remaining power, remaining power percentage, total battery capacity, etc.

[0037] The target battery remaining power ratio may be a ratio of the target battery remaining power to the target battery total capacity.

[0038] Step 102 : Acquire multiple temperature-power interval pairs; each temperature-power interval pair includes a temperature interval and a remaining power ratio interval.

[0039] In the embodiment of the present disclosure, the lengths of the temperature intervals within different pairs of temperature and power intervals are different; and / or the lengths of the remaining power percentage intervals within different pairs of temperature and power intervals are different.

[0040] The temperature range can be any temperature range within the battery's temperature range. The temperature range is determined based on the battery's minimum and maximum temperatures. The remaining power percentage range can be any remaining power percentage range within the battery's remaining power percentage range. The remaining power percentage range is determined based on the battery's minimum and maximum remaining power percentages, and can be, for example, a range from 0 to 1.

[0041] Step 103 : determining the aging impact degree according to the temperature and remaining power ratio of the target battery at each time point within a preset time period, and the impact factors of multiple temperature and power range pairs.

[0042] In the embodiment of the present disclosure, the impact factor can reflect the degree of influence of different temperature and power intervals on battery aging. Among them, the higher the temperature value within the temperature interval in the temperature and power interval pair, the higher the value of the remaining power ratio within the remaining power ratio interval in the temperature and power interval pair, the larger the value of the impact factor, and the greater the degree of influence on battery aging. Among them, the aging impact degree represents the influence on the aging degree of the target battery, that is, the influence of the remaining power ratio and temperature of the target battery on the aging degree of the target battery.

[0043] In one example, the impact factor of the temperature-to-electricity interval pair can be calculated based on the service life of a large number of batteries and the battery parameter information during use. In another example, the process of determining the impact factor of the temperature-to-electricity interval pair can be, for example, fixing the battery parameter information of the battery during use and obtaining the service life of the battery; and determining the impact factor by combining the service life of the battery and the fixed battery parameter information. In another example, the impact factor of the temperature-to-electricity interval pair can be determined manually based on experience, etc.

[0044] The target battery's temperature and remaining charge percentage at various points in the preset time period can be used to determine how long the target battery can remain within multiple temperature and charge intervals. The aging impact can then be determined by combining the influencing factors of these multiple temperature and charge intervals. The greater the aging impact, the shorter the target battery's service life.

[0045] Step 104 : When the aging impact degree is greater than or equal to the impact degree threshold, the charging cut-off voltage of the target battery is lowered.

[0046] In the disclosed embodiment, the target battery's charge cut-off voltage is lowered by a specified voltage. The specified voltage may be, for example, 15 mV. For example, if the specified voltage is 15 mV, the electronic device may lower the target battery's charge cut-off voltage by 15 mV.

[0047] In an embodiment of the present disclosure, after lowering the charging cut-off voltage of the target battery, the electronic device may further perform the following process: updating the preset time period according to the first step length to obtain an updated preset time period; the first step length is greater than or equal to the length of the preset time period, and the updated preset time period is later than the preset time period; and obtaining battery parameter information of the target battery within the updated preset time period for charging management.

[0048] The length of the preset time period can be determined according to the usage of the target battery. For example, the length of the preset time period can be 3 days, 5 days, 7 days, etc., and can be set according to actual needs.

[0049] It should be noted that after the charging cut-off voltage of the target battery is lowered, if it is determined that the aging impact is greater than or equal to the impact threshold based on the battery parameter information of the target battery within the updated preset time period, the charging cut-off voltage of the target battery can be lowered again until the minimum charging cut-off voltage is reached.

[0050] In an embodiment of the present disclosure, the electronic device may further perform the following process: when the aging impact is less than the impact threshold, maintaining the charge cut-off voltage of the target battery. It should be noted that if the electronic device determines to maintain the charge cut-off voltage of the target battery for N consecutive preset time periods, and the charge cut-off voltage is neither the minimum charge cut-off voltage nor the maximum charge cut-off voltage, then the charge cut-off voltage is increased.

[0051] In addition, to further ensure the service life of the target battery, when the aging impact is less than the impact threshold, the electronic device may also perform the following process: when the aging impact is less than the impact threshold, the preset time period is updated according to the second step length to obtain an updated preset time period; the second step length is less than the length of the preset time period, and the updated preset time period is later than the preset time period; and battery parameter information of the target battery within the updated preset time period is obtained to perform charging management. Specifically, when the preset time period is 7 days, the second step length can be, for example, 1 day or 2 days, and can be set according to actual needs.

[0052] In the charging management method of the embodiment of the present disclosure, battery parameter information of the target battery within a preset time period is obtained; the battery parameter information includes the temperature of the target battery and the remaining power ratio at each time point within the preset time period; a plurality of temperature-power interval pairs are obtained; the temperature-power interval pair includes a temperature interval and a remaining power ratio interval; the aging impact is determined according to the temperature and the remaining power ratio of the target battery at each time point within the preset time period, and the influencing factors of the plurality of temperature-power interval pairs; when the aging impact is greater than or equal to the impact threshold, the charging cut-off voltage of the target battery is lowered; wherein, the lowering of the charging cut-off voltage of the target battery can prevent the target battery from being in a high power state and a high temperature state for a long time, thereby ensuring the service life and usage efficiency of the target battery.

[0053] Figure 2 This is a flow chart of a charging management method according to another embodiment of the present disclosure. It should be noted that the charging management method according to this embodiment can be applied to a charging management device, which can be configured in an electronic device or chip so that the electronic device or chip can perform a charging management function. Figure 1 Based on the embodiment shown, Figure 2 As shown, the method includes the following steps:

[0054] Step 201 : Obtain battery parameter information of a target battery within a preset time period; the battery parameter information includes the temperature and remaining power percentage of the target battery at each time point within the preset time period.

[0055] Step 202 , obtaining a plurality of temperature-power interval pairs; each temperature-power interval pair includes a temperature interval and a remaining power ratio interval.

[0056] Step 203 : determining the duration for which the target battery stays within the multiple temperature-power interval pairs based on the temperature and remaining power ratio of the target battery at each time point within the preset time period, and the multiple temperature-power interval pairs.

[0057] In an embodiment of the present disclosure, the process of the electronic device executing step 203 may, for example, be as follows: for each temperature-electricity interval pair, multiple target time points are selected from various time points within a preset time period; the temperature of the target battery at the target time point is within the temperature interval of the temperature-electricity interval pair, and the remaining power ratio of the target battery at the target time point is within the remaining power ratio interval of the temperature-electricity interval pair; the total duration of multiple target time points is counted; and the total duration is determined as the maintenance duration of the target battery in the temperature-electricity interval pair.

[0058] The total duration of the multiple target time points is the cumulative duration obtained by accumulating the time at the multiple target time points.

[0059] For example, the temperature range includes five temperature intervals, and the remaining power percentage range includes six remaining power percentage intervals. The five temperature intervals are (temperature 2, temperature 1), (temperature 3, temperature 2), (temperature 4, temperature 3), (temperature 5, temperature 4), and (temperature n, temperature 5). The values ​​of temperature 1, temperature 2, temperature 3, temperature 4, temperature 5, ..., temperature n decrease in sequence.

[0060] The six remaining power percentage intervals are (percentage 1, maximum remaining power percentage), (percentage 2, percentage 1), (percentage 3, percentage 2), (percentage 4, percentage 3), (percentage n-1, percentage 4), and (percentage n, percentage n-1). The values ​​decrease in order from percentage 1 to percentage 2, percentage 3, percentage 4, percentage 5, ..., percentage n.

[0061] Among them, there are 7 temperature-electricity interval pairs. The temperature interval in the first temperature-electricity interval pair is (temperature 2, temperature 1), the remaining power ratio in the first temperature-electricity interval pair is (ratio 4, maximum remaining power ratio), and the impact factor of the first temperature-electricity interval pair is K1. The temperature interval in the second temperature-electricity interval pair is (temperature 2, temperature 1), the remaining power ratio in the second temperature-electricity interval pair is (ratio n-1, ratio 4), and the impact factor of the second temperature-electricity interval pair is K2. The temperature interval in the third temperature-electricity interval pair is (temperature 2, temperature 1), the remaining power ratio in the third temperature-electricity interval pair is (ratio n, ratio n-1), and the impact factor of the third temperature-electricity interval pair is K3. The temperature interval in the fourth temperature-electricity interval pair is (temperature 3, temperature 2), the remaining power ratio in the fourth temperature-electricity interval pair is (ratio 2, maximum remaining power ratio), and the impact factor of the fourth temperature-electricity interval pair is K4. The temperature interval in the fifth temperature-electricity interval pair is (temperature 3, temperature 2), the remaining power ratio in the fifth temperature-electricity interval pair is (ratio 5, ratio 3), and the impact factor of the fifth temperature-electricity interval pair is K5. The temperature interval in the sixth temperature-electricity interval pair is (temperature 4, temperature 3), the remaining power ratio in the sixth temperature-electricity interval pair is (ratio 2, maximum remaining power ratio), and the impact factor of the sixth temperature-electricity interval pair is K6. The temperature interval in the seventh temperature-electricity interval pair is (temperature 5, temperature 4), the remaining power ratio in the seventh temperature-electricity interval pair is (ratio 1, maximum remaining power ratio), and the impact factor of the seventh temperature-electricity interval pair is K7.

[0062] Step 204 : performing weighted summation processing on the maintenance time of the target battery in the multiple temperature-power interval pairs according to the impact factors of the multiple temperature-power interval pairs to obtain the aging impact degree.

[0063] In the embodiment of the present disclosure, in the above example, the calculation formula of the aging influence degree may be as shown in the following formula, for example.

[0064] R=K1*Time1+K2*Time2+K3*Time3+K4*Time4+K5*Time5+K6*Time6+K7*Time7.

[0065] K1 to K7 represent the impact factors of the seven temperature-to-energy range pairs, respectively. Time1 to Time7 represent the duration of the target battery within the seven temperature-to-energy range pairs, respectively. R represents the aging impact.

[0066] Step 205 : When the aging impact degree is greater than or equal to the impact degree threshold, the charging cut-off voltage of the target battery is lowered.

[0067] It should be noted that the detailed description of steps 201 to 202 and step 205 can be found in Figure 1 Steps 101 to 102 and step 104 in the illustrated embodiment will not be described in detail here.

[0068] In the charging management method of the embodiment of the present disclosure, battery parameter information of the target battery within a preset time period is obtained; the battery parameter information includes the temperature of the target battery and the remaining power ratio at each time point within the preset time period; a plurality of temperature-power interval pairs are obtained; the temperature-power interval pair includes a temperature interval and a remaining power ratio interval; according to the temperature and the remaining power ratio of the target battery at each time point within the preset time period, and the plurality of temperature-power interval pairs, the maintenance time of the target battery in the plurality of temperature-power interval pairs is determined; according to the influencing factors of the plurality of temperature-power interval pairs, the maintenance time of the target battery in the plurality of temperature-power interval pairs is weighted and summed to obtain an aging impact degree; when the aging impact degree is greater than or equal to the impact degree threshold, the charging cut-off voltage of the target battery is lowered, wherein the lowering of the charging cut-off voltage of the target battery can avoid the target battery being in a high power state and a high temperature state for a long time, thereby ensuring the service life and usage efficiency of the target battery.

[0069] The following examples are given to illustrate this. Figure 3 The figure below is a flow chart of charging management. Figure 3 In the process, the electronic device can start collecting battery-related information within 7 days; after collecting 7 days of data, the battery high temperature and full charge condition R are judged; if R (aging impact) is greater than or equal to N (impact threshold), the battery full charge voltage (charging cut-off voltage) is reduced by 15mV, and then the existing 7 days of data are deleted, and data collection is restarted for judgment processing; if R is less than N, the battery full charge voltage is reduced by 0mV, that is, the current full charge voltage (charging cut-off voltage) is maintained, and then the data of the first day is deleted and the data of the next day (the data of the first day after the existing 7 days) is added for judgment processing.
