Description

Technical Field

[0001] The present invention relates to the technical field of charger adjustment, and in particular to an artificial intelligence-based charger data intelligent adjustment system and method. Background Art

[0002] As power-consuming devices continue to demand higher quality, safety, reliability, convenience, immediacy, and adaptability to specific occasions and geographical environments, contact-based power transmission is increasingly unable to meet these needs. Currently, wireless chargers are widely used to charge mobile devices such as smartphones and tablets. Furthermore, as technology continues to evolve, wireless charging will also be increasingly applied to electric vehicles, smart homes, and other fields, bringing even greater convenience to our lives.

[0003] However, when a wireless charger charges multiple charging terminals simultaneously, it often uses a uniform charging power from the start to the end of charging, without automatically adjusting according to the actual situation of the charging terminal; prolonged high charging power can easily damage the battery of the charging terminal and reduce its service life; prolonged low charging power can easily cause the charging terminal with low real-time remaining power to lose power, reducing the overall charging efficiency.

[0004] Therefore, the present invention discloses an artificial intelligence-based charger data intelligent adjustment system and method to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a charger data intelligent adjustment system and method based on artificial intelligence to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solution: a charger data intelligent adjustment method based on artificial intelligence, the method comprising the following steps:

[0007] S1: When the charger starts working, it collects charging information and basic information of the charging terminal, and pre-processes the charging information and basic information of the charging terminal to generate a historical remaining power increment curve and a historical remaining power decrement curve;

[0008] S2: Analyze the power usage of the charging terminal based on the basic information of the charging terminal, form a battery health status evaluation set, and evaluate the battery health status of the charging terminal;

[0009] S3: Based on the battery health status assessment results of the charging terminal, the maximum charging power of the charging terminal is calculated, the real-time remaining power of the charging terminal is divided into ranges, and a charging power allocation model for the charging terminal is constructed;

[0010] S4: Adaptively adjust the charging power of the charging terminal according to the charging power distribution model of the charging terminal, monitor the charging terminal in real time, and provide prompts and safety adjustments for abnormal situations.

[0011] According to the above scheme, in S1, the charging terminals that are connected to the charger are grouped into a set, which is recorded as CT = {CT i |i∈[1,N]};i is a positive integer;where CT i represents the charging terminal with sequence number i in the charging terminal set, and N represents the total number of charging terminals in the charging terminal set;

[0012] The charging information of the charging terminal includes the charging power of the charger to the charging terminal;

[0013] The basic information of the charging terminal includes the temperature, remaining power, total power at factory and real-time maximum capacity of the charging terminal battery;

[0014] Generate a historical temperature curve based on the historical temperature of the battery of the charging terminal, wherein the historical temperature curve is a curve showing the historical temperature changing over time, and one historical temperature curve corresponds to one historical temperature function;

[0015] Generate a historical remaining power curve according to the historical remaining power of the battery of the charging terminal and the charging power of the charger to the charging terminal, the historical remaining power curve including a historical remaining power decrement curve and a historical remaining power increment curve, the historical remaining power decrement curve including a first historical remaining power decrement curve and a second historical remaining power decrement curve, and the historical remaining power increment curve including a first historical remaining power increment curve and a second historical remaining power increment curve;

[0016] According to the above scheme,

[0017] When the user only charges the charging terminal, the charging power of the charger to the charging terminal is associated with the historical change per unit time of the remaining power of the battery of the charging terminal, the historical change per unit time of the remaining power when the user only charges the charging terminal is recorded as a first historical remaining power increment, and a first historical remaining power increment curve is generated based on the first historical remaining power increment; the first historical remaining power increment curve is a curve showing how the first historical remaining power increment changes over time, and each first historical remaining power increment curve corresponds to a first historical remaining power increment function;

[0018] When the user does not charge the charging terminal, a change in the historical remaining power per unit time is recorded as a first historical remaining power decrement, and a first historical remaining power decrement curve is generated based on the first historical remaining power decrement; the first historical remaining power decrement curve is a curve of the first historical remaining power decrement changing over time, and each first historical remaining power decrement curve corresponds to a first historical remaining power decrement function;

[0019] When a user charges and uses the charging terminal at the same time, the charging power of the charger for the charging terminal is obtained at each moment, and the unit time change of the associated historical remaining power is found from the first historical remaining power increment function of the charging terminal, which is recorded as the second historical remaining power increment. A second historical remaining power increment curve is generated based on the second historical remaining power increment; the second historical remaining power increment curve is a curve showing the change of the second historical remaining power increment over time, and each second historical remaining power increment curve corresponds to a second historical remaining power increment function; the second historical remaining power decrement is calculated based on the historical remaining power when charging and using the terminal simultaneously and the second historical remaining power increment, and a second historical remaining power decrement curve is generated based on the second historical remaining power decrement; the second historical remaining power decrement curve is a curve showing the change of the second historical remaining power decrement over time, and each second historical remaining power decrement curve corresponds to a second historical remaining power decrement function.

[0020] 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 usage and charging status of the charging terminal. Analyzing both situations is conducive to more accurate identification of the battery health status of the charging terminal.

[0021] According to the above scheme, in S2, the specific steps are as follows:

[0022] 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;

[0023] S202: Analyze 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;

[0024] S203: assembling a battery health status evaluation set based on total values ​​of remaining power changes, total values ​​of abnormal temperatures, and remaining capacity in different historical periods, and calculating a battery health status value of the charging terminal based on the battery health status evaluation set;

[0025] According to the above solution, in step S201,

[0026] Setting a threshold for the historical remaining power reduction, extracting function segments whose historical remaining power reduction is greater than the set threshold from the historical remaining power reduction function to generate a first function segment set; and calculating a total value of the historical remaining power reduction for the first function segment set;

[0027] 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; the total value of the historical remaining power increment is calculated for the second function segment set.

[0028] Separate thresholds are set for the historical remaining power decrease and increase. When a charging terminal charges and consumes power too quickly, it can easily damage the battery. Analyzing these two situations separately helps more accurately identify the battery health status of the charging terminal.

[0029] According to the above solution, 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 function segments whose historical temperatures are greater than the first temperature threshold are extracted from the historical temperature function to generate a third function segment set; and function segments whose historical temperatures are less than the second temperature threshold are extracted from the historical temperature function to generate a fourth function segment set.

[0030] 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;

[0031] The remaining capacity is calculated using the factory total power and the real-time maximum capacity; the remaining capacity is the ratio of the real-time maximum capacity to the factory total power.

[0032] According to the above solution, in step S203, the total value of the historical remaining power decrement, the total value of the historical remaining power increment, the total value of the temperature of the third function segment set, the total value of the temperature of the fourth function segment set 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 evaluation item with sequence number j in the battery health status evaluation set;

[0033] 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.

[0034] 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 iPerform evaluation calculations. The specific calculation formula is as follows:

[0035] ;

[0036] where α j Indicates the battery health status assessment item BHS （i，j） The weight of .

[0037] 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:

[0038] P i max =P i 额 ×β i ;

[0039] Among them, P i 额 Indicates charging terminal CT i Rated charging power, β i Indicates charging terminal CT i Charging safety factor;

[0040] The charging terminal CT i Corrected charging safety factor β i 修 The specific calculation formula is as follows:

[0041] ;

[0042] 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 ;

[0043] Setting the maximum charging power of the battery of the charging terminal can effectively keep the charging power of the charging terminal within a relatively safe range, effectively ensure the safety of the battery and increase the battery life.

[0044] The real-time remaining power of the battery is divided into three intervals according to the real-time remaining power setting of the first threshold and the second threshold, wherein the real-time remaining power of the battery is divided into three intervals, wherein the range from the first threshold to the full power is recorded as the first range interval; the range from the second threshold to the first threshold is recorded as the second range interval; and the range from zero to the second threshold is recorded as the third range interval;

[0045] 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;

[0046] 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 decrement 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;

[0047] The real-time remaining power is divided into three ranges. Different charging powers are set for each range, and different response measures can be taken according to different situations.

[0048] Setting a third range charging power threshold within the third range ensures that the remaining power level continues to increase even when the user uses the charging terminal within this range, effectively preventing device power outages and improving the user experience. Furthermore, not directly using the maximum charging power within the third range reduces thermal and chemical stress on the battery, thereby extending battery life.

[0049] Setting the charging power equal to the maximum charging power in the second range can speed up the charging speed and improve the charging efficiency;

[0050] In S3, a charging terminal usage time estimation model is also included;

[0051] A threshold is set for the time the user does not use the charging terminal. If the user does not use the charging terminal for a period greater than the set threshold, the charging terminal is charged to a second threshold of the real-time remaining power, and then the charging power of the charging terminal is adjusted to a charging power associated with the historical remaining power reduction;

[0052] 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 from 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 historical remaining power increment;

[0053] According to the average first-time use time node of the charging terminal and the charging time, the charging time node before the first-time 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.

[0054] 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 charging power associated with 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 the charging time node before the first use of the charging terminal for charging can ensure the status of the mobile phone and improve the user experience.

[0055] 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. 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 real-time 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 real-time remaining power reduction is the same as the historical remaining power reduction.

[0056] 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.

[0057] Another aspect of the present application provides an artificial intelligence-based charger data intelligent adjustment system, which is applied to the above-mentioned artificial intelligence-based charger data intelligent adjustment method. The system includes a charging terminal data acquisition module, a data management center, a battery health status assessment module, a charging power allocation module, and an early warning adjustment module;

[0059] The data management center is used to store data collected during system operation and to pre-process charging information and basic information of charging terminals;

[0060] The battery health status assessment module analyzes the power usage of the charging terminal based on the pre-processed basic information of the charging terminal, forms a battery health status assessment set, and assesses the battery health status of the charging terminal;

[0061] The charging power allocation module calculates the maximum charging power of the charging terminal based on the battery health status evaluation result of the charging terminal, divides the real-time remaining power of the charging terminal into range intervals, and constructs a charging power allocation model for the charging terminal;

[0062] The early warning adjustment module adaptively adjusts the charging power of the charging terminal according to the charging power distribution model of the charging terminal, monitors the charging terminal in real time, and provides prompts and safety adjustments for abnormal situations.

[0063] The data management center includes a data storage library and a pre-processing unit;

[0064] The data repository is used to store data collected and during system operation;

[0065] 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;

[0066] The battery health status assessment module includes an assessment item processing unit and an assessment calculation unit;

[0067] The evaluation item processing unit calculates the total value of the historical remaining power reduction and the total value of the historical remaining power increase according to different historical remaining power functions, calculates the total temperature value of the third function segment set and the total temperature value of the fourth function segment set according to the historical temperature function, and calculates the remaining capacity according to the factory total power and the real-time maximum capacity;

[0074] 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.

[0075] Compared with the prior art, the present invention has the following beneficial effects:

[0076] 1. Generating a historical remaining power increment function and a historical remaining power decrement function based on the historical remaining power can effectively distinguish between the power usage and charging status of the charging terminal. Analyzing both situations facilitates more accurate identification of the battery health status of the charging terminal. Using multiple battery health status assessment items to form a battery health status assessment set, the battery of the charging terminal is evaluated, further improving the accuracy of battery health status assessment.

[0077] 2. Setting the maximum charging power of the battery of the charging terminal can effectively keep the charging power of the charging terminal within a relatively safe range, effectively ensuring the safety of the battery and extending the battery life.

[0078] 3. Divide the real-time remaining power into three ranges. Different charging powers are set for each range, enabling tailored responses to different situations. A third-range charging power threshold is set within the third range. This ensures the real-time remaining power continues to increase even when the user uses the charging terminal within this range, effectively preventing device power outages and improving the user experience. By not directly using the maximum charging power within the third range, the battery's thermal and chemical stresses are reduced, thereby extending battery life. Setting the charging power equal to the maximum charging power in the second range accelerates charging and improves charging efficiency. When the real-time remaining power is within the first range, the charging terminal usage time estimation model enables the user to adjust the charging power to a value equal to the historical remaining power reduction even if the charging terminal is not used for an extended period. This effectively ensures the real-time remaining power while reducing thermal and chemical stress on the battery, thereby extending battery life. Calculating charging time before the first use of the charging terminal ensures the phone's health and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

If the user does not use the charging terminal for a period greater than the set threshold, the charging terminal is charged to a second threshold of the real-time remaining power, and then the charging power of the charging terminal is adjusted to a charging power associated with the historical remaining power reduction;

[0125] 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 from 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 historical minimum remaining power increment;

[0126] According to the average first-time use time node of the charging terminal and the charging time, the charging time node before the first-time 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.

[0127] Example 2: In this example, the charging terminal usage time estimation model is used to estimate the time node when the user first uses the charging terminal when waking up in the morning. The user is set to a 3-hour inactivity threshold. Assuming that the user stops using the phone at 22:00 on the first night of the first day, the real-time remaining power of the charging terminal is obtained at 1:00 on the second day. If the real-time remaining power of the charging terminal is less than the second threshold of the real-time remaining power, charging continues at the originally set charging power. When the real-time remaining power of the charging terminal reaches the second threshold of the real-time remaining power, the charging power of the charging terminal is adjusted to equal the charging power associated with the historical remaining power reduction.

[0128] The charging terminal usage time estimation model extracts the time nodes of the first use of the charging terminal after the charging terminal has not been used for a period greater than the set threshold from the historical basic information, forming a set. In this real-time example, the set is T = {6:45, 6:50, 6:55}. The calculated average time node of the first use of the charging terminal is 6:50. The minimum historical remaining power increment is 3W. It takes half an hour to fully charge from the second threshold of the real-time remaining power, so the charging time node is 6:20.

[0129] S4: Adaptively adjust the charging power of the charging terminal according to the charging power distribution model of the charging terminal, monitor the charging terminal in real time, and provide prompts and safety adjustments for abnormal situations.

[0130] 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, which 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 real-time 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 real-time remaining power reduction is the same as the historical remaining power reduction.
