[0008] Generating a historical remaining power increment function and a historical remaining power decrement function based on the historical remaining power can effectively distinguish the power consumption and charging conditions of the charging terminal; analyzing both conditions is conducive to more accurately identifying the battery health status of the charging terminal; According to the above scheme, in S2, the specific steps are as follows: S201: Analyze the historical remaining power, and calculate the total value of the historical remaining power change according to the historical remaining power function corresponding to different historical remaining power curves; S202: Analyze the historical temperatures and calculate the total value of abnormal temperatures in the historical temperatures; calculate the remaining capacity based on the total factory power and the real-time maximum capacity; S203: forming a battery health status evaluation set according to different historical total values ​​of remaining power changes, total values ​​of abnormal temperatures, and remaining capacities, and calculating a battery health status value of the charging terminal according to the battery health status evaluation set; According to the above scheme, in step S201, Setting a threshold for the historical remaining power reduction, extracting a function segment whose historical remaining power reduction is greater than the set threshold from the historical remaining power reduction function, and generating a first function segment set; calculating the total value of the historical remaining power reduction for the first function segment set; A threshold is set for the historical remaining power increment, and function segments whose historical remaining power increment is greater than the set threshold are extracted from the historical remaining power increment function to generate a second function segment set; and the total value of the historical remaining power increment is calculated for the second function segment set.

[0009] Thresholds are set for the historical remaining power decrease and historical remaining power increase. When the charging terminal charges and consumes power too quickly, it is easy to damage the battery. Analyzing the above two situations separately is conducive to more accurately identifying the battery health status of the charging terminal. According to the above scheme, in step S202, a first temperature threshold and a second temperature threshold are set for the historical temperature, the first temperature threshold is greater than the second temperature threshold, and a function segment whose historical temperature is greater than the first temperature threshold is extracted from the historical temperature function to generate a third function segment set; a function segment whose historical temperature is less than the second temperature threshold is extracted from the historical temperature function to generate a fourth function segment set; Calculating a third function segment set temperature total value and a fourth function segment set temperature total value for the third function segment set and the fourth function segment set respectively; The remaining capacity is calculated using the total factory power and the real-time maximum capacity; the remaining capacity is the ratio of the real-time maximum capacity to the total factory power.

[0010] According to the above scheme, in step S203, the total value of the historical remaining power reduction, the total value of the historical remaining power increment, the total value of the third function segment set temperature, the total value of the fourth function segment set temperature and the inverse of the remaining capacity are used to generate a battery health status evaluation set, which is recorded as BHS i ={BHS （i，j） |j∈[1,5]}; where BHS （i，j） Indicates charging terminal CT i The battery health status assessment item with sequence number j in the battery health status assessment set; A battery health status evaluation set is formed by using multiple battery health status evaluation items to evaluate the battery of the charging terminal, further improving the accuracy of battery health status evaluation.

[0011] Normalize the battery health status evaluation item values ​​in the battery health status evaluation set; calculate the battery health status value SOH of the charging terminal according to the battery health status evaluation set; i Perform evaluation calculation, the specific calculation formula is as follows: SOH i =∑\s\do 3(j=1)5 (BHS （i，j） ×α j ); where α j Indicates the battery health status assessment item BHS （i，j） The weight of .

[0012] According to the above solution, in S3, the charging terminal CT is checked according to the battery health status value. i Set the maximum charging power P i max; The specific calculation formula is as follows: P i max =P i 额 ×β i ; Where P i 额 Indicates charging terminal CT i Rated charging power, β i表示 Charging terminal CT i The charging safety factor; The charging terminal CT i Corrected charging safety factor β i 修 The specific calculation formula is as follows: ; Among them SOH min represents the minimum value of the battery health status value in the charging terminal set, ε is the correction coefficient; if β i 修 ≥1, then the charging safety factor β i =1; if β i 修 <1, then the charging safety factor β i =β i 修 ; Setting the maximum charging power of the battery of the charging terminal can effectively keep the charging power of the charging terminal within a safer range, effectively ensure the safety of the battery and increase the service life of the battery.

[0013] According to the real-time remaining power, the first threshold of the real-time remaining power and the second threshold of the real-time remaining power are set to divide the real-time remaining power of the battery into three intervals, wherein the first threshold of the real-time remaining power to the full power is recorded as the first range interval; the second threshold of the real-time remaining power to the first threshold of the real-time remaining power is recorded as the second range interval; and zero to the second threshold of the real-time remaining power is recorded as the third range interval; A third range interval charging power threshold is set for the third range interval, and the third range interval charging power threshold is greater than the maximum value of the historical remaining power decrement in the historical remaining power decrement function; a first range interval charging power threshold is set for the first range interval, and the first range interval charging power threshold is greater than the minimum value of the historical remaining power increment in the historical remaining power increment function, and the first range interval charging power threshold is less than the third range interval charging power threshold; When the real-time remaining power of the charging terminal is within the third range, the charging power of the charging terminal is set to be within the range from the maximum value of the historical remaining power reduction to the charging power threshold of the third range; when the real-time remaining power of the charging terminal is within the second range, the charging power of the charging terminal is set to be equal to the maximum charging power; when the real-time remaining power of the charging terminal is within the first range, the charging power of the charging terminal is set to be within the range from the minimum value of the historical remaining power increment to the charging power threshold of the first range; The real-time remaining power is divided into three ranges. Different charging powers are set for the ranges used, so different response measures can be taken according to different situations. A third range interval charging power threshold is set in the third range interval, so that even if the user uses the charging terminal in the range interval, the real-time remaining power can be ensured to continue to increase, which can effectively prevent the device from being powered off and improve the user experience; and not directly using the highest charging power in the third range interval can reduce the thermal stress and chemical stress of the battery, thereby extending the battery life; In the second range, setting the charging power equal to the maximum charging power can speed up the charging speed and improve the charging efficiency; In S3, a charging terminal usage time estimation model is also included; A threshold is set for the time when the user does not use the charging terminal. If the user does not use the charging terminal for a time greater than the set threshold, after the real-time remaining power of the charging terminal is charged to a second threshold of the real-time remaining power, the charging power of the charging terminal is adjusted to a charging power associated with the historical remaining power reduction; The charging terminal usage time estimation model extracts the time node of the first use of the charging terminal after the charging terminal has not been used for a period greater than a set threshold in the historical basic information, calculates the average time node of the first use of the charging terminal, and calculates the charging time based on the charging power associated with the minimum value of the historical remaining power increment; According to the average first use time node of the charging terminal and the charging time, the charging time node before the first use time node of the charging terminal is calculated, and the charging terminal is charged with the charging power associated with the minimum historical remaining power increment.

[0014] When the real-time remaining power is within the first range, the charging terminal usage time estimation model can be used to enable the user to adjust the charging power to a charging power equal to the historical remaining power reduction when the charging terminal is not used for a long time. This can effectively ensure the real-time remaining power while reducing the thermal stress and chemical stress of the battery, thereby extending the battery life. Calculating and charging the charging time node before the first use of the charging terminal can ensure the status of the mobile phone and improve the user experience.

[0015] According to the above scheme, in S4, the charging power of the charging terminal is adaptively adjusted according to the charging power allocation model of the charging terminal, and the temperature of the charging terminal is monitored in real time. When the temperature of the charging terminal is greater than the set threshold, the user is prompted with an abnormal situation, and the prompt includes the cause of the abnormality and a charging power adjustment option. The charging power adjustment option includes a subsequent charging power option and a stop charging option. The subsequent charging power in the subsequent charging power option is greater than the charging power associated with the historical remaining power reduction; if the user does not select the adjustment option for a long time, the system automatically selects it; the calculation method of the historical remaining power reduction is the same as the historical remaining power reduction.

[0016] When the temperature of the charging terminal exceeds the set threshold, the control system will prompt the user, reduce the charging power or stop charging to protect the charging terminal from damage.

[0018] The data management center includes a data storage library and a pre-processing unit; The data repository is used to store data during acquisition and system operation; The preprocessing unit generates a historical temperature curve according to the historical temperature of the battery of the charging terminal; generates different historical remaining power functions according to the historical remaining power of the battery of the charging terminal, the charging power of the charger to the charging terminal, and the actual charging and discharging conditions; The battery health status assessment module includes an assessment item processing unit and an assessment calculation unit; The evaluation item processing unit calculates the total value of the historical remaining power reduction and the total value of the historical remaining power increment according to different historical remaining power functions, calculates the total value of the third function segment set temperature and the total value of the fourth function segment set temperature according to the historical temperature function, and calculates the remaining capacity according to the factory total power and the real-time maximum capacity; The evaluation and calculation unit evaluates and calculates the battery health state of the charging terminal according to the battery health state evaluation set; The charging power allocation module includes a maximum charging power calculation unit and a charging power setting unit; The maximum charging power calculation unit calculates a charging safety factor according to the battery health status value, and calculates a maximum charging power according to the charging safety factor and a rated charging power of the charging terminal; The charging power setting unit allocates and sets the charging power of the charging terminal according to the range of the real-time remaining power of the charging terminal; The early warning adjustment module includes an early warning monitoring unit and a prompt adjustment unit; The early warning monitoring unit is used to monitor the temperature of the charging terminal in real time, and when the temperature of the charging terminal is greater than a set threshold, the status is sent to the prompt adjustment unit; The prompt adjustment unit is used to prompt the user of abnormal situations, and the prompt includes the cause of the abnormality and charging power adjustment options.

Different charging powers are set for the range intervals used, so that different response measures can be taken according to different situations. The third range interval charging power threshold is set in the third range interval. Even if the user uses the charging terminal in this range interval, the real-time remaining power can be guaranteed to continue to increase, which can effectively prevent the device from being powered off and improve the user experience.
