On the one hand, the performance data collection of charging piles under different working conditions (such as different voltages, currents, power loads and temperature environments) is not comprehensive enough, and it is impossible to accurately grasp its actual operating conditions under complex working conditions. On the other hand, existing technologies make it difficult to effectively predict the life of charging piles, and it is impossible to assess in advance the time when charging piles may fail, making it difficult to formulate a reasonable maintenance plan.

[0050] It should be noted that the charging pile aging test module of the present embodiment can be directly applied to the factory inspection of charging piles by charging pile manufacturers and even destructive charging pile experiments, so as to improve the quality of charging piles. Furthermore, the charging pile aging feedback module of the present embodiment can be directly applied to the use of charging pile managers, and based on the communication connection between the charging pile aging test module and the charging pile aging feedback module, the charging pile manufacturer can realize the service upgrade of the charging pile manager.

It provides rich and accurate data support for the subsequent accurate analysis of the aging of the charging pile, judgment of the fault type, and prediction of the life span, and improves the reliability of safety monitoring.

[0063] The charging pile aging monitoring learning model that meets the preset model accuracy threshold is output and defined as the charging pile aging monitoring model.

[0064] Based on the above, this embodiment uses existing deep learning technology to construct and train a charging pile aging monitoring learning model, thereby achieving efficient and accurate aging monitoring model generation. By inputting charging test data into the model, the fault knowledge base and life assessment algorithm are continuously updated to adapt to various actual situations. In a simple example, when encountering a new type of fault, the fault knowledge base can be updated based on data-driven knowledge to improve the fault analysis capability. Finally, a model that meets the accuracy threshold is obtained, which can more accurately monitor the safety of the charging pile, effectively reduce the risk of failure, and extend the service life of the charging pile.

[0067] Based on the test charging data, the features of the faults that do not belong to the expert knowledge are extracted to obtain the data-driven knowledge, and the data-driven knowledge is verified, and the verified data-driven knowledge is saved in the fault knowledge base.

[0068] Based on the above, this embodiment uses the acquisition of expert knowledge combined with test charging data verification, as well as the extraction and verification of new fault data-driven knowledge, to achieve a comprehensive update of the fault knowledge base. Expert knowledge provides a theoretical basis for fault analysis, such as relying on empirical knowledge when judging circuit faults. Data-driven knowledge supplements newly emerging complex fault conditions. In a simple example, the fault is caused by the charging compatibility problem between the charging pile and the new electric vehicle. The combination of the two makes the fault knowledge base more complete, improves the ability to identify and analyze various fault types, and ensures the safe operation of the charging pile.

[0069] Specifically, the life evaluation algorithm is updated based on the charging test data, specifically:

[0078] in, is a voltage failure threshold value established based on experience known to those skilled in the art, and the voltage attenuation ( For the Secondary measurement voltage), Its probability density function is, The probability of failure of the charging pile caused by the calculated voltage can be calculated based on this formula. The probability of failure caused by voltage at different time points can be calculated to obtain the voltage-related life distribution function. , indicating that at time The cumulative probability of charging pile failure caused by internal voltage is calculated. Based on this, the , , and 's construction.

[0079] Based on the above, this embodiment uses the failure probability function of each factor in the test charging data to update the comprehensive life calculation formula, thereby achieving a more accurate life prediction. By analyzing the failure conditions caused by voltage, current, power and temperature factors in the historical test data, the failure probability function of each factor is determined, such as the adjustment of the temperature failure probability function under the high temperature environment in summer in a certain area. This enables the life assessment algorithm to better adapt to actual working conditions, more accurately estimate the life of the charging pile, provide a basis for the reasonable arrangement of maintenance and replacement plans, and reduce operating costs.

[0082] The fourth performance parameter data, the fifth performance parameter data and the sixth performance parameter data are packaged to obtain the active charging data.

[0083] Based on the above, this embodiment uses the time series-based collection and packaging of performance parameter data of each unit in service to accurately grasp the actual operating conditions of the current charging piles. During the actual charging process, real-time data of the current power supply unit, charging pile unit and load unit can be obtained in a timely manner, such as high current and high power data collected during peak hours at commercial charging stations. These data provide actual operation references for the charging pile aging monitoring model, making the monitoring and prediction results more realistic, helping to timely discover potential safety hazards and ensure the reliable operation of the charging piles.
