[0067] 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 invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0068] Figure 1 This is a charging strategy adjustment method process shown in the embodiment of the present disclosure Figure 1 ,like Figure 1 As shown, it is applied to the server. The charging strategy adjustment method includes the following steps:

[0069] S11, obtaining battery capacity information of batteries of corresponding models of multiple terminal devices during power supply;

[0070] S12, determining aging information of the corresponding battery model based on the battery capacity information of the plurality of terminal devices;

[0071] S13: adjusting the charging strategy of the battery of the corresponding model according to the aging information.

[0072] In the embodiments of the present disclosure, the terminal devices include mobile terminals and wearable electronic devices. The mobile terminals include smart phones, notebooks or tablet computers. The wearable electronic devices include smart watches or smart bracelets, which are not limited in the embodiments of the present disclosure.

[0073] The terminal device also includes a first control processing module, through which the battery capacity information of the battery in the terminal device can be obtained.

[0074] The server establishes a communication connection with the multiple terminal devices. Through the communication connection, the server can obtain the battery capacity information of the corresponding models of batteries during the power supply process sent by the multiple terminal devices. Among them, the terminal devices can send the battery capacity information to the server at preset intervals. The preset time can be set according to actual needs. For example, the preset time can be set to 8 hours, 2 days or 1 month, which is not limited in the embodiments of the present disclosure.

[0075] In the disclosed embodiment, the battery capacity information includes: the current capacity value of the battery corresponding to at least two historical charging cycles. For example, the current capacity value of the battery at the 100th charging cycle is 3500mAh; the current capacity value of the battery at the 700th charging cycle is 3300mAh.

[0076] The capacity value is the amount of charge that the battery can release for external use. When the battery completes a charging cycle, the number of charging cycles increases by one.

[0077] It should be noted that as the number of charging cycles increases, the battery capacity will be lost. This capacity loss may be caused by different usage behaviors or different usage environments. Based on this, the above-mentioned server of the embodiment of the present disclosure obtains the battery capacity information of batteries of corresponding models of multiple terminal devices during the power supply process. The battery capacity information is the actual battery capacity information of different users under different usage behaviors or different usage environments, which can accurately reflect the differences between the battery capacity information of different users.

[0078] For example, Figure 2 Figure 1 is a schematic diagram of battery capacity distribution. Figure 2 As shown in the figure, the horizontal axis is the number of charging cycles, and the vertical axis is the battery capacity value under different charging cycles. The standard capacity of the battery is 3500mAh. Figure 2 The middle horizontal line is the threshold value 3500*80%. Among them, the batteries above the horizontal line have a battery capacity value greater than the threshold value at different charging cycle times; the batteries below the horizontal line have a battery capacity value less than the threshold value at different charging cycle times.

[0079] In the disclosed embodiment, the battery capacity information can reflect the aging information of the battery. The aging information includes: the aging speed of the battery, and / or the aging acceleration of the battery. For example, the larger the difference between the battery capacity values ​​of two adjacent charging cycles in the battery capacity information, the faster the battery aging speed; the smaller the difference between the battery capacity values ​​of two adjacent charging cycles in the battery capacity information, the slower the battery aging speed.

[0080] It should be noted that as the number of charging cycles increases, the battery will age. However, based on different usage scenarios and different usage behaviors, different models of batteries have different aging information. Therefore, the charging strategy of the corresponding model of battery can be adjusted based on the battery aging information.

[0081] In the embodiment of the present disclosure, the charging strategy of the corresponding battery model is adjusted according to the aging information, including: when the aging information of the battery indicates that the battery is abnormally aged, the charging strategy of the battery is adjusted. In this way, the charging strategy can be adjusted in time when the battery is abnormally aged, thereby improving the battery performance and reducing the battery's durability.

[0082] It should be noted that the battery aging information indicates abnormal battery aging, including: the aging rate of the battery at the next charging cycle is greater than the aging rate threshold; or, the aging acceleration of the battery at the next charging cycle is greater than the aging acceleration threshold; or, the next capacity ratio of the battery at the next charging cycle is less than or equal to the preset ratio threshold.

[0083] The capacity ratio is the ratio of the battery capacity to the minimum capacity of the battery. The battery capacity is the actual capacity of the battery, and the minimum capacity is the theoretical capacity of the battery.

[0084] The above-mentioned aging speed threshold value, aging acceleration threshold value and preset ratio threshold value can be determined based on the theoretical values ​​of the battery cell materials under different charging cycles, or can be determined based on the theoretical values ​​and actual user needs, which is not limited by the embodiments of the present disclosure.

[0085] In the embodiment of the present disclosure, the charging strategy is different charging methods for the battery. The charging strategy may include charging methods under different charging modes; and may also include charging methods under different charging scenarios.

[0086] It should be noted that the adjustable charging objects are different in different charging modes. For example, when adjusting the charging strategy, the charging voltage in the constant voltage charging mode is adjusted; the charging current in the constant current charging mode is adjusted. For another example, when adjusting the charging strategy, the charging load and charging power in the scenario of parallel power supply and charging are adjusted; the charging power and charging temperature are adjusted in the scenario of high ambient temperature.

[0087] The preset adjustment ratios of the adjustable charging objects under the above different charging modes are different. The preset adjustment ratio can be greater than 0 and less than 1. For example, when adjusting the charging strategy, the charging power of the high ambient temperature scene is lowered, and the preset adjustment ratio is 0.3%; for another example, when adjusting the charging strategy, the charging voltage of the constant voltage charging mode is lowered, and the preset adjustment ratio is 0.5%, which is not limited in the embodiments of the present disclosure.

[0088] It should be noted that the server stores different charging strategies corresponding to different aging anomalies. When the next capacity ratio corresponding to the next charging cycle of the battery is less than or equal to the preset ratio threshold, the difference between the next capacity ratio and the preset ratio threshold can be set to be positively correlated with the above adjustment ratio. For example, when the difference is 10%, the corresponding adjustment ratio can be 0.3; when the difference is 20%, the corresponding adjustment ratio is 0.5, which is not limited in the embodiments of the present disclosure.

[0089] In the disclosed embodiment, after the server adjusts the charging strategy of the battery of the corresponding model according to the aging information, the charging strategy adjustment method further includes: sending the adjusted charging strategy to the plurality of terminal devices.

[0090] In this way, multiple terminal devices charge their respective batteries based on the adjusted charging strategy, which can reduce the aging of batteries of different terminal devices and extend the service life of the batteries.

[0091] It can be understood that the embodiment of the present disclosure first determines the aging information based on the battery capacity information of the corresponding models of batteries of multiple terminal devices during the power supply process, and then adjusts the charging strategy of the corresponding model of battery based on the aging information. In this way, compared with adjusting the charging strategy according to the material characteristics of the battery itself, the aging information of the embodiment of the present disclosure can accurately reflect the aging of the battery under different usage behaviors and different usage scenarios during the charging process, and then the charging strategy adjusted based on the accurate aging information can be applicable to different batteries, effectively reducing the situation where the battery is not durable due to different situations, thereby extending the service life of the battery. At the same time, the embodiment of the present disclosure adjusts the subsequent charging strategy of the battery based on the battery capacity information of the power supply process, that is, the adjustment method is a method of predicting the battery charging strategy based on the actual battery capacity information, and then the battery charging strategy can be adjusted in time before the aging of the battery worsens, further reducing the situation where the battery is not durable due to different situations.

[0092] In some embodiments, determining the aging information of the corresponding battery models based on the battery capacity information of the multiple terminal devices includes:

[0093] Based on the battery capacity information, obtaining aging statistical data of the battery of the corresponding model;

[0094] Based on the aging statistical data, an aging trend of the battery of the corresponding model is determined.

[0095] In the embodiment of the present disclosure, the battery models corresponding to different terminal devices may be the same or different. After obtaining the battery capacity information of multiple terminal devices during the power supply process, the battery capacity information may be counted to obtain aging statistical data.

[0096] It should be noted that the different aging conditions of batteries of different models during use are obtained by collecting statistics on the battery capacity information of multiple terminal devices. The aging statistical data of batteries of different models obtained by statistics include: obtaining multiple aging data corresponding to batteries of different models based on the battery capacity information; collecting statistics on the multiple aging data by a preset statistical method to obtain aging statistical data corresponding to batteries of different models. In this way, aging statistical data of batteries of corresponding models of multiple terminal devices can be obtained.

[0097] Exemplarily, the above-mentioned preset statistical methods include elimination method, mean method, least neighbor method, ratio regression method or decision tree method, which is not limited in the embodiments of the present disclosure.

[0098] In some embodiments, the aging statistics of the battery of the corresponding model are obtained based on the battery capacity information, including: based on the battery capacity information, obtaining a plurality of historical capacity values ​​corresponding to a plurality of historical charging cycle numbers of the battery of the corresponding model.

[0099] It should be noted that, since a battery has a large number of rechargeable cycles, the interval difference between the historical capacity values ​​corresponding to two adjacent charging cycles is small. Therefore, in order to reduce the situation where the statistical data processing volume is too large and the statistical time is long, a cycle number statistical interval can be set when statistical data is collected. The cycle number statistical interval can be set according to actual needs. For example, the cycle number statistical interval can be set to 50 times or 100 times, which is not limited in the embodiments of the present disclosure.

[0100] After obtaining the aging statistical data, the aging trend of the corresponding battery model can be determined based on the aging statistical data. The aging trend represents the aging degree of the battery under the next number of charging cycles.

[0101] It can be understood that the embodiment of the present disclosure counts the battery capacity information of multiple terminal devices, and the statistical data volume is large, which can obtain more accurate aging statistics of batteries of corresponding models of terminal devices, and thus obtain more accurate aging trends.

[0102] In some embodiments, determining the aging trend of the battery of the corresponding model based on the aging statistical data includes:

[0103] Determine a ratio of the historical capacity value to a preset minimum capacity value of the corresponding battery model, and obtain a plurality of capacity ratios corresponding to the plurality of historical charging cycle numbers;

[0104] Based on the plurality of capacity ratios, obtaining two adjacent capacity ratios at adjacent historical charging cycle times;

[0105] Based on two adjacent capacity ratios, an aging acceleration corresponding to the next number of charging cycles of the battery of the corresponding model is determined.

[0106] In the embodiment of the present disclosure, the above-mentioned preset minimum capacity value includes but is not limited to the rated capacity value of the battery. For example, the rated capacity value of the battery is 3500mAh or 20000mAh.

[0107] The above historical capacity values ​​include but are not limited to the actual capacity values ​​of the battery under the historical number of charging cycles. For example, the rated capacity of the battery is 3500mAh, and the actual capacity value of the battery under the 100th charging cycle is 3500mAh; the actual capacity value of the battery under the 500th charging cycle is 2800mAh.

[0108] The above capacity ratio is the ratio between the current capacity value and the minimum capacity value. Figure 3 As shown, the capacity ratio of the battery at the 100th charging cycle is 99%; the capacity ratio of the battery at the 400th charging cycle is 90%.

[0109] It should be noted that the battery capacity ratio is negatively correlated with the battery aging degree. When the battery capacity ratio is smaller, the current battery aging degree is higher, which can reflect that the aging of the battery in the next charging cycle may be abnormal aging. Based on this, the battery charging strategy needs to be adjusted in case of abnormal aging to improve the battery durability.

[0110] In the disclosed embodiment, the adjacent historical charging cycle numbers may include: the first historical charging cycle number and the second historical charging cycle number in descending order. For example, when the total number of historical charging cycles is 400 and the cycle number statistical interval is 100, the first historical charging cycle number in descending order is 400, and the second historical charging cycle number in descending order is 300. That is, the capacity ratio of the 300th charging cycle and the capacity ratio of the 400th charging cycle are obtained.

[0111] The method of determining the aging acceleration of the battery at the next charging cycle number based on two adjacent capacity ratios includes: determining two historical aging accelerations in two adjacent charging cycles based on the two adjacent capacity ratios; and determining the aging acceleration at the next charging cycle number based on the two historical aging accelerations.

[0112] It should be noted that the above two historical aging accelerations include: a first historical aging acceleration corresponding to the first historical charging cycle number and a second historical aging acceleration corresponding to the second historical charging cycle number in descending order. In other words, the embodiment of the present disclosure determines the aging acceleration at the next charging cycle number based on the aging acceleration corresponding to the two largest historical charging cycle numbers, so that the predicted aging acceleration at the next charging cycle number can be more closely matched with the actual aging acceleration, thereby enabling a more accurate adjustment of the charging strategy.

[0113] In the disclosed embodiment, the number of historical charging cycles corresponding to the first historical aging acceleration is greater than the number of historical charging cycles corresponding to the second historical aging acceleration. The above-mentioned determination of the aging acceleration at the next charging cycle number based on the two historical aging accelerations includes:

[0114] When the first historical aging acceleration and the second historical aging acceleration are the same, determining that the aging acceleration at the next charging cycle number is the first historical aging acceleration or the second historical aging acceleration;

[0115] When the first historical aging acceleration is different from the second historical aging acceleration, the aging acceleration at the next charging cycle is determined to be the first historical aging acceleration; or, the difference between the aging acceleration at the next charging cycle and the first historical aging acceleration is determined to be less than a preset difference.

[0116] For example, when the maximum number of charging cycles in history is 400 among at least two historical charging cycle numbers, the cycle number statistical interval is 100, and the aging acceleration of the 400th charging cycle is different from the historical aging acceleration of the 300th charging cycle, the determined aging acceleration of the 500th charging cycle may be the same as the historical aging acceleration of the 400th charging cycle; or, it may also be determined by the preset difference and the aging acceleration of the 400th charging cycle. The preset difference may be set according to actual conditions, for example, the preset difference may be set between 0.05 and 0.5, which is not limited in the embodiments of the present disclosure.

[0117] It can be understood that the embodiment of the present disclosure uses the capacity ratio to determine the aging acceleration of the battery corresponding to the next number of charging cycles, that is, the capacity ratio obtained during the charging process can accurately predict the subsequent aging acceleration of the battery, thereby providing reliable data for the subsequent precise adjustment of the charging strategy.

[0118] In some embodiments, adjusting the charging strategy of the battery of the corresponding model according to the aging information includes:

[0119] Based on the aging acceleration, determining a next capacity ratio of the battery of the corresponding model corresponding to the next number of charging cycles;

[0120] When the next capacity ratio is less than or equal to a preset ratio threshold, the charging strategy of the battery of the corresponding model is adjusted.

[0121] That is to say, the disclosed embodiment adjusts the battery charging strategy by predicting the next capacity ratio value based on the battery aging acceleration during the power supply process. In this way, the battery aging under different charging behaviors and different charging scenarios can be taken into account, making the predicted next capacity ratio value more accurate, thereby improving the accuracy of adjusting the charging strategy.

[0122] The above preset ratio threshold can be set according to actual needs. For example, the preset ratio threshold can be set to 80% or 70%, which is not limited in the embodiment of the present disclosure.

[0123] For example, Figure 4 As shown, when the next capacity ratio of the next charging cycle number determined by the aging acceleration is less than 80%, it indicates that the predicted battery aging is abnormal, and the battery charging strategy needs to be adjusted.

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

[0125] When the next capacity ratio is greater than the preset ratio threshold, the current charging strategy of the battery of the corresponding model is maintained.

[0126] It is understandable that the prediction that the next capacity ratio is greater than the preset ratio threshold indicates that the battery is in a normal state, and thus there is no need to adjust the battery charging strategy.

[0127] For example, Figure 5 As shown, when the next capacity ratio of the next charging cycle number determined by the aging acceleration is greater than 80%, it indicates that there is no need to adjust the battery charging strategy and the current charging strategy of the battery can be maintained.

[0128] In some embodiments, adjusting the charging strategy of the battery of the corresponding model includes:

[0129] Obtaining a preset adjustment ratio of the battery of the corresponding model;

[0130] Determine the current charging parameters of the battery of the corresponding model under the current charging strategy;

[0131] Based on the current charging parameter and the preset adjustment ratio, a charging strategy for the battery of the corresponding model is determined.

[0132] The preset adjustment ratio is used to adjust the current charging parameters. The preset adjustment ratio is in the range of 0 to 1. For example, the preset adjustment ratio can be set to 0.3, 0.5 or 0.7, which is not limited in the embodiment of the present disclosure.

[0133] In an embodiment of the present disclosure, a charging strategy of a battery is determined based on current charging parameters and a preset adjustment ratio, including: determining adjusted charging parameters based on the product of the current charging parameters and the preset adjustment ratio; and forming an adjusted charging strategy based on the adjusted charging parameters.

[0134] In some embodiments, the current charging parameter includes at least one of the following: current charging voltage; current charging current; current charging load; current charging temperature.

[0135] In the embodiment of the present disclosure, when the current charging parameter is the current charging voltage, the adjusted charging voltage of the battery can be determined by the current charging voltage and the preset adjustment ratio; when the current charging parameter is the current charging current, the adjusted charging current of the battery can be determined by the current charging current and the preset adjustment ratio.

[0136] It can be understood that by adjusting the battery charging strategy by presetting the adjustment ratio and the current charging parameters, a charging strategy that is more suitable for the current battery can be obtained, thereby reducing the battery's durability caused by different situations and extending the battery's service life.

[0137] In some embodiments, adjusting the charging strategy of the battery of the corresponding model according to the aging information includes:

[0138] According to the aging information, adjusting the charging strategy included in the factory settings of the battery of the corresponding model;

[0139] or,

[0140] According to the aging information, the current charging strategy of the battery of the corresponding model is adjusted, wherein the current charging strategy is: the charging strategy currently used by the battery and is different from the charging strategy set by the factory.

[0141] In the embodiment of the present disclosure, the charging strategy included in the factory settings of the battery of the corresponding model may include presetting the adjusted charging strategy into the factory settings when the battery of the terminal device is factory set. In this way, the charging strategy of the unused new terminal device can be adjusted, thereby increasing the adjustment scenarios of the charging strategy.

[0142] The above adjustment of the current charging strategy of the battery of the corresponding model may include adjusting the currently used charging strategy by the adjusted charging strategy. In this way, the battery in use can be directly charged using the adjusted charging strategy.

[0143] For example, based on the adjusted charging strategy, charging adjustment may be performed at the 400th charging cycle or the 500th charging cycle, which is not limited in the embodiments of the present disclosure.

[0144] It can be understood that the adjusted charging strategy in the embodiment of the present disclosure can not only adjust the charging strategy included in the factory settings of the battery, but also adjust the current charging strategy of the battery. In this way, the adjustment scenarios of the charging strategy can be expanded, so that batteries in different usage situations can use the adjusted charging strategy to reduce the battery's durability and extend the battery's service life.
