Description

Technical Field

[0001] This application relates to the technical field of battery performance detection, and particularly to a method and system for detecting the electrical performance of a battery combination cover plate. Background Art

[0002] As a key component of a lithium-ion battery, the battery combination cover plate is not only used to seal the battery and prevent electrolyte leakage, but also for internal circuit connection and signal transmission of the battery. The quality of its electrical performance directly affects the safety, stability and service life of the battery. Electrical performance problems of the battery combination cover plate may cause battery short circuit, overheating or even explosion. How to perform accurate and efficient electrical performance detection has become a key link. Traditional electrical performance detection of battery combination cover plates mostly uses single-dimensional detection equipment, such as only detecting insulation resistance or only detecting conduction performance, which cannot comprehensively evaluate the electrical performance of the battery combination cover plate, and is prone to missed detection and misdetection. Moreover, electromagnetic interference in the actual detection environment, the accuracy error of the equipment itself, and jitter during the transmission process all affect the accuracy of the detection results. At the same time, the existing detection process lacks an effective misjudgment suppression mechanism, resulting in insufficient reliability of the detection results, and it is difficult to perform flexible and efficient transmission processing on the cover plate according to the detection results.

The terms used herein are only for the purpose of describing the embodiments of the present application.

[0023] An embodiment of the present application provides an electrical performance detection method for a battery combination cover plate, as Figure 1 shown. The method includes:

[0024] Step S100, when the suction cup grabs the battery combination cover plate to the detection station, generate an equipment inspection signal.

[0025] Preferably, when the suction cup for grasping the battery combination cover plate grasps and places the battery combination cover plate at the working position (detection station) for electrical performance detection, an equipment spot-check signal is generated. Specifically, from the perspective of equipment operation, an equipment spot-check signal is generated to trigger the inspection procedure of the automatic detection equipment for the battery cover plate, and to confirm whether each key component of the equipment is in a normal working state. For example, whether the circuit of the detection equipment is normal, whether the sensor is sensitive and accurate, and whether the parameter settings of the detection instrument are correct, etc., so as to ensure the reliability and accuracy of the electrical performance detection results of the battery combination cover plate.

[0026] Step S200, perform a spot-check on the automatic detection equipment for the battery cover plate based on the equipment spot-check signal, and generate an equipment spot-check result.

[0027] Preferably, after receiving the equipment spot-check signal, the detection equipment starts self-verification, including hardware inspection, parameter inspection, and function testing, to determine whether it is in a normal working state. Specifically, the hardware inspection may include mechanical component inspection, electrical component inspection, and sensor inspection. The mechanical component inspection refers to inspecting the mechanical structures in the equipment for grasping, transporting, and positioning the battery combination cover plate, such as suction cups, conveyor belts, jigs, etc., to check for wear, looseness, deformation, etc., to ensure that the battery combination cover plate can be accurately operated; the electrical component inspection refers to detecting the electrical components of the equipment, including power modules, wires and cables, relays, contactors, etc., such as checking whether the power supply is stable and whether there are faults such as short circuits, open circuits, and leakage in each electrical component, to ensure the electrical safety and normal operation of the equipment; the sensor inspection refers to detecting the sensitivity, accuracy, and stability of various sensors (such as position sensors, pressure sensors, temperature sensors, etc.) in the equipment.

[0028] Preferably, the parameter inspection may include detection program inspection and parameter setting inspection. Among them, the detection program inspection refers to checking whether the detection software program running on the equipment is normal, whether there are program errors, loopholes, or version incompatibilities, etc., to ensure that the software can correctly control the operation process of the equipment and accurately collect and process detection data; the parameter setting inspection refers to checking whether the detection parameter settings of the equipment are correct, including detection voltage, current, time, etc., to ensure that they match the specifications and detection requirements of the battery combination cover plate.

[0029] Preferably, the functional test may include a simulation detection test and a data acquisition and transmission test. Among them, the simulation detection test means that the device performs a detection action without detecting the battery combination cover plate, and checks whether each function of the device can be realized normally. For example, simulating the action of the suction cup grasping the cover plate, transporting it to the detection station, and performing electrical performance detection, observing whether the device can accurately execute according to the preset process and requirements, and whether the collaborative work between components is smooth; the data acquisition and transmission test means checking whether the data acquisition unit of the device can accurately acquire various data during the detection process, such as resistance value, voltage value, current value, etc., and correctly transmit the data to verify the accuracy and stability of data acquisition and transmission. Finally, the detection results are combined to generate the equipment spot-check result, clearly indicating whether the equipment passes the spot-check. If there are problems with the equipment, the spot-check result details the problems, such as a certain component being damaged, parameter settings being incorrect, etc., so that maintenance personnel can repair and adjust in time to ensure that the equipment is in the best working state before officially performing the electrical performance detection of the battery combination cover plate, thereby improving the accuracy and reliability of the detection results.

[0030] Further, step S200 further includes step S210, based on the equipment spot-check signal, retrieving the standard cover plate sample and the defective cover plate sample; step S220, performing a spot-check on the battery cover automatic detection equipment according to the standard cover plate sample to obtain the first spot-check result; step S230, performing a spot-check on the battery cover automatic detection equipment according to the defective cover plate sample to obtain the second spot-check result; step S240, generating the equipment spot-check result according to the first spot-check result and the second spot-check result.

[0031] Preferably, after receiving the equipment spot-check signal, the standard cover plate sample and the defective cover plate sample are automatically retrieved from the corresponding storage locations. Among them, the standard cover plate sample is a battery combination cover plate that meets the quality standards and electrical performance indicators, representing the ideal product state. The defective cover plate sample is a battery combination cover plate with various known defects or not meeting the electrical performance requirements, such as poor electrode connection, poor insulation performance, abnormal resistance value, etc.; then the standard cover plate sample is placed in the battery cover automatic detection equipment for detection. The equipment detects the electrical performance indicators of the standard sample according to the preset detection procedures and parameters, such as measuring its resistance, voltage, current and other parameters, checking its insulation performance, electrode connection situation, etc., and then comparing the detected data with the standard values of the standard sample to judge whether the equipment can accurately detect the performance indicators of the standard sample and whether there are deviations or errors. If the detection result of the equipment is consistent with the standard value, it means that the equipment detects the standard sample normally, and the corresponding detection data and results are recorded, which is the first spot-check result.

[0032] Preferably, then use the defective cover plate sample to conduct a spot check on the equipment. The equipment detects the electrical performance of the defective sample. Since the defective sample has known defects, the equipment can detect these defects and give corresponding alarm or prompt information. For example, if there is a problem with the connection of a certain electrode of the defective sample, the equipment should be able to detect abnormal resistance value or poor current transmission of the electrode; by observing the detection results of the equipment on the defective sample, judge whether the equipment can accurately identify various defective states, record the detection data, alarm information of the equipment on the defective sample, and whether it can correctly locate and describe the defective defects, etc., to form the second spot check result. Finally, generate the final equipment spot check result by integrating the first spot check result and the second spot check result. If the detection result of the equipment on the standard cover plate sample is accurate and it can correctly identify various defects of the defective cover plate sample, it is considered that the equipment is operating normally and passes the spot check; if there is a deviation when the equipment detects the standard sample, or it cannot accurately identify some defects of the defective sample, analyze the possible problems of the equipment according to the specific situation, such as sensor failure, detection algorithm error, unreasonable parameter setting, etc., and record the problems in detail in the equipment spot check result, so as to more comprehensively and accurately evaluate the performance and working state of the automatic battery cover plate detection equipment, thus ensuring the accuracy and reliability of the detection result of the battery combination cover plate.

[0033] Further, step S220 further includes step S221, detecting the electrical performance of the standard cover plate sample according to the automatic battery cover plate detection equipment to obtain standard sample detection data; step S222, comparing the standard sample detection reference data and the standard sample detection data to generate the equipment detection accuracy; step S223, judging whether the equipment detection accuracy meets the detection accuracy constraint to generate the first spot check result.

[0034] Preferably, the automatic battery cover plate detection equipment detects the electrical performance of the standard cover plate sample to obtain standard sample detection data, which may include but are not limited to voltage, current, resistance, capacitance, insulation resistance, etc. Comparing the standard sample detection reference data and the standard sample detection data includes calculating the difference or deviation rate for each electrical performance index respectively, and then calculating the relative error between the detected value and the reference value to represent the equipment detection accuracy. Among them, the standard sample detection reference data is the reference data determined by a high-precision measuring device, representing the true electrical performance of the standard sample, and is used to measure the detection accuracy of the equipment; judging whether the equipment detection accuracy meets the detection accuracy constraint, where the detection accuracy constraint is the accuracy threshold set according to the production quality requirements and detection standards of the battery cover plate. If the equipment detection accuracy is within the constraint range, it means that the equipment can accurately detect the electrical performance of the standard sample and meets the detection requirements; on the contrary, if it exceeds the constraint range, it indicates that there is a problem with the detection accuracy of the equipment and it may not be able to meet the actual detection needs; finally, generate the first spot check result according to the judgment result.

[0035] Further, step S200 further includes generating a device operation and maintenance signal when the device inspection result is an abnormal inspection result.

[0036] Preferably, if the device inspection result is an abnormal inspection result, it indicates that the device has situations that do not meet the normal operation requirements, such as unqualified detection accuracy, component failures, unstable performance, etc. An automatic device operation and maintenance signal is generated to notify the device operation and maintenance personnel for maintenance, repair, and debugging to ensure that the device can be restored to the normal operation state and guarantee the accuracy and reliability of the automatic battery cover detection work.

[0037] Step S300, based on the device inspection result, control the automatic battery cover detection device to perform multi-dimensional electrical performance detection on the battery combination cover to obtain the first cover detection sequence.

[0038] Step S300 further includes step S310. When the device inspection result is a normal inspection result, perform a positive and negative profile high-voltage test on the battery combination cover according to the automatic battery cover detection device to obtain the cover profile high-voltage test data; step S320, when the device inspection result is a normal inspection result, perform a positive and negative withstand voltage test on the battery combination cover according to the automatic battery cover detection device to obtain the cover withstand voltage test data; step S330, when the device inspection result is a normal inspection result, perform an insulation resistance test on the battery combination cover according to the automatic battery cover detection device to obtain the cover resistance test data; step S340, when the device inspection result is a normal inspection result, perform a flatness test on the battery combination cover according to the automatic battery cover detection device to obtain the cover flatness test data; step S350, construct the first cover detection sequence according to the cover profile high-voltage test data, the cover withstand voltage test data, the cover resistance test data, and the cover flatness test data.

[0039] Preferably, when the equipment inspection result is normal, use the battery cover automatic detection equipment to conduct a positive and negative profile high-voltage test on the battery combination cover, that is, simulate the high-voltage situation that the battery may encounter during actual use. By contacting the positive and negative electrodes of the battery cover with specific profile electrodes and applying a certain high voltage, the detection equipment will collect relevant electrical parameters during this process, such as current and voltage changes, etc., to form the cover profile high-voltage test data, which is mainly used to test the electrical performance and safety of the battery cover under high-voltage environment, and ensure that it can withstand the specified high voltage without problems such as breakdown and leakage; similarly, on the premise of normal equipment inspection, conduct a positive and negative withstand voltage test on the battery combination cover, that is, apply a certain voltage, but the key is to detect the maximum voltage value that the battery cover can withstand, and whether it can maintain good insulation performance and electrical stability under the specified voltage, record the state of the cover at different voltage stages and relevant electrical data during the test, and obtain the cover withstand voltage test data, so as to evaluate whether the withstand voltage ability of the battery cover meets the requirements.

[0040] Preferably, after the equipment inspection is normal, conduct an insulation resistance test, that is, use an insulation resistance test instrument to detect the insulation performance of the battery combination cover, measure the resistance value between its positive and negative electrodes and the shell or other non-conductive parts, obtain and record the resistance value and relevant test conditions and other information, form the cover resistance test data, and then ensure that the battery cover has good insulation performance, prevent leakage, and ensure the safety of battery use; when the equipment inspection is normal, use the battery cover automatic detection equipment to conduct a flatness test on the battery combination cover, usually using laser measurement, optical measurement, etc., to scan or measure the surface of the cover, obtain the height information of each point on the cover surface, and calculate the flatness parameters of the cover through data analysis, that is, the cover flatness test data, so as to ensure that the surface flatness of the battery cover meets the production requirements, ensure that it can cooperate well with other battery components, and avoid assembly problems or affecting the battery performance caused by poor flatness. Finally, integrate the cover profile high-voltage test data, cover withstand voltage test data, cover resistance test data and cover flatness test data to generate the first sequence of cover detection, which comprehensively reflects the quality status of the battery combination cover in terms of electrical performance, insulation performance and physical dimension accuracy, and can judge whether the battery combination cover meets the quality standard.

[0041] Step S400, perform interference compensation on the detection scenario of the first sequence of cover detection to obtain the second sequence of cover detection.

[0042] Step S400 further includes step S410 of collecting detection scenario parameters for the first sequence of cover plate detections to obtain four-element detection scenario data; step S420 of performing anomaly detection based on the four-element detection scenario data to obtain a four-element scenario anomaly detection result; step S430 of identifying interference in electrical performance detection based on the four-element scenario anomaly detection result to obtain a four-element scenario anomaly interference factor; and step S440 of performing mapping compensation on the first sequence of cover plate detections according to the four-element scenario anomaly interference factor to generate the second sequence of cover plate detections.

[0043] Preferably, collecting detection scenario parameters for the first sequence of cover plate detections includes collecting device status information, such as the operating parameters of the device, the working status of sensors, the operating temperature, operating speed, and working status of each component of the device, as well as environmental data, such as the environmental temperature, humidity, light intensity, and ambient electromagnetic field intensity during detection, to reflect the actual situation during detection, and integrating the collected device status and environmental data to generate a data set containing four-dimensional information (cover plate profiling high-voltage test, cover plate withstand voltage test, insulation resistance test, and cover plate flatness test), that is, four-element detection scenario data. Then, anomaly detection is performed on the four-element detection scenario data to identify whether there are any abnormal situations. Specifically, by comparing with a preset normal data range or historical data, it is determined whether each test data is within a reasonable fluctuation range, while considering the potential impact of device status and environmental data on the test results. If a certain data point deviates from the normal range, or the relationship between the data shows an unexpected situation, it is determined that there is an anomaly, and thus a four-element scenario anomaly detection result is obtained, such as indicating which test data or scenario parameters are abnormal, as well as the degree and type of the anomaly, etc.

[0044] Preferably, electrical performance detection interference recognition is performed according to the quaternary scenario anomaly detection result. Specifically, electrical performance detection (such as profiling high-voltage test, withstand voltage test, and insulation resistance test) is susceptible to environmental factors (such as electromagnetic interference, humidity, etc.) and equipment's own factors (such as equipment aging, component failure, etc.). Further analyze the abnormal situation and the interference factors in the electrical performance detection process to determine the specific interference factors, that is, the quaternary scenario anomaly interference factors, which may include the influence of environmental humidity on the insulation resistance test, the interference of electromagnetic interference on the profiling high-voltage test, or the abnormal withstand voltage test result caused by the failure of a certain component of the equipment, etc.; then, according to the identified quaternary scenario anomaly interference factors, perform mapping compensation on the data in the first sequence of cover plate detection. For example, if the environmental humidity affects the insulation resistance test data, correct the original insulation resistance test data according to the relationship between humidity and insulation resistance; if the abnormal profiling high-voltage test data is caused by the failure of a certain component of the equipment, adjust the test data accordingly according to the calibration data or historical experience of the equipment; to eliminate or reduce the influence of interference factors on the detection result, make the data more truly reflect the actual performance of the battery pack cover plate, so as to obtain the second sequence of cover plate detection, which can more accurately reflect the true quality status of the battery pack cover plate, can more accurately judge whether the battery pack cover plate meets the quality standard, and whether it is necessary to adjust the production process or detection equipment.

[0045] Step S500, input the second sequence of cover plate detection into the cover plate electrical performance detection model to obtain the first result of cover plate detection.

[0046] Step S500 further includes step S510, retrieving the electrical performance detection reference sample according to the cover plate specification model of the battery pack to obtain the reference sequence of cover plate detection; step S520, performing mapping comparison between the reference sequence of cover plate detection and the second sequence of cover plate detection to construct a quaternary comparison vector of cover plate detection; step S530, inputting the quaternary comparison vector of cover plate detection into the cover plate electrical performance detection model to generate the first result of cover plate detection.

[0047] Preferably, battery pack cover plates of different specification models have different design requirements and performance standards. According to the specific specification model of the battery pack cover plate to be detected currently, retrieve the electrical performance detection reference sample in the database. Among them, the database stores relevant information of cover plates of various specification models, including the reference sample data of electrical performance detection. Find the reference sample data of electrical performance detection corresponding to this specification model to form the reference sequence of cover plate detection, which includes the standard values or expected values of various electrical performance detection indexes of the battery pack cover plate of this specification model in the ideal state, such as the standard voltage value of the profiling high-voltage test, the standard withstand time and voltage of the withstand voltage test, the standard resistance value range of the insulation resistance, and the standard allowable error of the flatness, etc.

[0048] Preferably, the cover plate detection reference sequence is compared in detail with the processed second cover plate detection sequence, including comparing and analyzing the detection data of each corresponding element in the two sequences, that is, the detection data for profiling high-voltage testing, withstand voltage testing, insulation resistance testing, and flatness testing, to construct a four-element comparison vector of the comparison result, that is, the cover plate detection four-element comparison vector. Each element represents the difference between the actual value and the reference value of the corresponding detection item. For example, the first element in the vector represents the deviation degree of the profiling high-voltage test data from the reference data, and the second element represents a similar deviation situation for the withstand voltage test, and so on. Through the four-element comparison vector, the differences between the battery pack cover plate and the standard requirements in various electrical performance detection indicators can be comprehensively and intuitively reflected.

[0049] Preferably, the constructed cover plate detection four-element comparison vector is used as the input data for the cover plate electrical performance detection model. Through the analysis and processing of the input four-element comparison vector, a comprehensive evaluation result of the battery pack cover plate electrical performance is obtained, that is, the first cover plate detection result, which may include specific evaluations of various detection indicators, prompts for potential problems, and possible improvement measures to be taken, etc. For example, some elements in the four-element comparison vector indicate that there are large deviations between the detection data and the reference data. The model identifies problems with the cover plate in the corresponding electrical performance aspects and clearly points them out in the detection result. Among them, a large amount of data related to the electrical performance detection of the battery cover plate is collected, including the detection data of different specifications and models of cover plates, such as profiling high-voltage test data, withstand voltage test data, insulation resistance test data, flatness test data, etc. At the same time, information such as the corresponding cover plate specifications and models, equipment status, and environmental data is recorded. The collected data is labeled to determine whether the electrical performance of each sample cover plate is qualified and whether there are specific types of abnormal conditions, etc. The labeled information serves as the label in supervised learning; then the data is preprocessed, including removing noise, duplicate data, and filling in missing values in the data, and then standardized processing is performed to convert data with different features into the same scale range; then features affecting the cover plate electrical performance detection result are extracted through Fourier transform, etc. A prediction model is constructed based on a machine learning model (such as decision tree, support vector machine, artificial neural network, etc.). The preprocessed data is divided into a training set and a validation set, trained with the training set, and evaluated with the test set to obtain a cover plate electrical performance detection model that can analyze and judge the electrical performance status of the battery pack cover plate according to the input comparison vector.

[0050] Step S600: Perform misjudgment suppression verification according to the first cover plate detection result to obtain the second cover plate detection result, and perform dual-band adaptive transfer on the battery pack cover plate according to the second cover plate detection result.

[0051] Preferably, during the detection process, various factors may interfere, resulting in the possibility of misjudgment in the first result of the cover plate detection. Perform misjudgment suppression verification on the first result of the cover plate detection. For example, use statistical analysis methods to analyze a large amount of detection data, establish distribution models for normal samples and abnormal samples, and judge whether it may be a misjudgment based on the position of the first result in the model; conduct comprehensive judgment based on ensemble learning combined with multiple different detection models to avoid misjudgment that may occur in a single model; it is also possible to correct the monitoring results that do not conform to common sense based on historical experience data, and then obtain the second result of the cover plate detection, which can more truly reflect the actual situation of the battery pack cover plate. Then, control the transmission of the battery pack cover plate according to the second result of the cover plate detection, including performing dual-belt adaptive transmission, that is, using two conveyor belts to transmit the cover plate, and parameters such as the speed and position of the conveyor belt can be adaptively adjusted according to the detection result of the cover plate. Specifically, if the detection result indicates that the cover plate is qualified, the cover plate will be transmitted to the next production link at a normal speed; if the detection result shows that there are some minor problems with the cover plate, the speed will be reduced for more careful inspection or marking of the cover plate; and if the cover plate is determined to be unqualified, it will be transmitted to a specific area for isolation or scrapping treatment; thus, classification processing of battery pack cover plates with different quality conditions is realized, production efficiency and product quality are improved, and it also helps to realize the automation and intelligence of the production process.

[0052] Further, step S600 further includes step S610 of collecting detection operation parameters according to the first result of the cover plate detection to obtain four-element detection operation data; step S620 of performing deviation detection according to the four-element detection operation data to determine the electrical performance detection deviation factor; step S630 of controlling the battery cover automatic detection device to perform compensation detection on the battery pack cover plate according to the electrical performance detection deviation factor to obtain cover plate compensation detection data; step S640 of correcting the second sequence of the cover plate detection according to the cover plate compensation detection data to obtain the third sequence of the cover plate detection; step S650 of inputting the third sequence of the cover plate detection into the cover plate electrical performance detection model to obtain the second result of the cover plate detection.

[0053] Preferably, detection operation parameters are collected from the first result of the cover plate detection, which may include the operating parameters of the detection equipment (such as voltage, current, test time, etc.), the environmental parameters during the detection process (such as temperature, humidity, etc.), and the parameters related to the battery combination cover plate (such as the size and material of the cover plate). The collected parameters are sorted into four-element detection operation data, and then deviation detection is performed based on the four-element detection operation data, including comparing and analyzing the four-element detection operation data with the preset standard parameters to check whether there are any deviations, that is, judging whether the data in each dimension exceeds the normal fluctuation range and the degree of deviation, and then determining the electrical performance detection deviation factor, a factor that can reflect the overall deviation degree of the electrical performance detection operation parameters, used to quantify the difference between the detection operation parameters and the standard state.

[0054] Preferably, according to the electrical performance detection deviation factor, the battery cover plate automatic detection equipment is controlled to perform compensation detection on the battery combination cover plate. Specifically, the electrical performance detection deviation factor is analyzed to determine the possible problematic links and the severity of the problems during the detection process, and then corresponding compensation detection strategies are formulated, which may include adding detection items (if the deviation factor indicates that the result of a certain detection item may be inaccurate, for example, the parameters of the flatness test deviate greatly, additional flatness detection points may be added), changing detection parameters (such as the voltage value of the withstand voltage test deviates from the standard, the voltage may be adjusted to the correct value and the withstand voltage test is performed again, and the test time or number of times may be appropriately increased according to the size of the deviation factor to obtain more accurate results), or repeating certain detection steps (when the deviation factor indicates that there may be an abnormality in a certain detection step, that detection step is repeated, such as when the result of the insulation resistance test is deviated due to a short-term interference of the detection equipment, the insulation resistance test needs to be performed again after eliminating the interference); then, according to the determined compensation detection strategy, the battery cover plate automatic detection equipment is controlled to perform corresponding operations to detect the battery cover plate combination and record the cover plate compensation detection data.

[0055] Preferably, the cover plate compensation detection data is incorporated into the second sequence of the cover plate detection and updated and corrected to obtain the third sequence of the cover plate detection, which can more accurately reflect the actual electrical performance status of the battery combination cover plate. Finally, the third sequence of the cover plate detection is used as input data and input into the cover plate electrical performance detection model for processing, and the second result of the cover plate detection is output, which can more truly reflect the electrical performance quality status of the battery combination cover plate.

[0056] Further, step S620 further includes step S621, performing deviation identification based on the four - element detection operation data to obtain a four - element operation deviation identification result; step S622, evaluating the influence of the four - element operation deviation identification result on the first cover plate detection result to obtain a four - element operation deviation influence coefficient; step S623, determining whether the four - element operation deviation influence coefficient is greater than or equal to an operation deviation influence threshold to obtain a four - element deviation influence judgment result; step S624, mapping the multi - dimensional electrical performance detection factors according to the four - element deviation influence judgment result to generate the electrical performance detection deviation factor.

[0057] Preferably, the four - element detection operation data is compared and analyzed with pre - set standard parameters, and for each dimension of data, it is judged whether it deviates from the normal state. For example, for the operation parameters of the positive and negative electrode profiling high - voltage test, positive and negative electrode withstand voltage test, insulation resistance test, and flatness test, deviation identification of voltage, current, test time, flatness value, etc. is performed to obtain a four - element operation deviation identification result, corresponding to the deviation conditions of the four detection dimensions, such as mild deviation, moderate deviation, severe deviation, etc.; then based on the four - element operation deviation identification result, the influence degree of the deviation of each dimension on the first cover plate detection result is evaluated, including quantifying the correlation between each detection dimension and the final detection result and the severity of the deviation, to obtain a four - element operation deviation influence coefficient, that is, the influence coefficient corresponding to different detection dimensions, used to represent the relative influence degree of the deviation of each dimension on the first cover plate detection result. The closer the coefficient is to 1, the greater the influence of the deviation of this dimension on the detection result; the closer the coefficient is to 0, the smaller the influence.

[0058] Preferably, it is determined whether the four - element operation deviation influence coefficient is greater than or equal to an operation deviation influence threshold. Here, the operation deviation influence threshold is a threshold set for the operation deviation influence coefficient of each dimension, used to judge whether the deviation of this dimension reaches the degree that needs attention, and then a four - element deviation influence judgment result is obtained. Each element corresponds to a detection dimension, indicating whether the operation deviation influence coefficient of this dimension is greater than or equal to the threshold; finally, according to the four - element deviation influence judgment result, comprehensive consideration and mapping processing are performed on the multi - dimensional electrical performance detection factors such as the positive and negative electrode profiling high - voltage test, positive and negative electrode withstand voltage test, insulation resistance test, and flatness test. If the deviation influence coefficient of a certain dimension is greater than or equal to the threshold, it means that the detection result of this dimension may have a greater impact on the overall electrical performance detection, and then a factor that can comprehensively reflect the deviation situation in the entire electrical performance detection process is obtained, that is, the electrical performance detection deviation factor, used to quantify the deviation degree between the electrical performance detection result and the ideal state.
