AI Technical Summary

Technical Problem

Existing DC charging cable torsional tensile performance testing devices have limitations in online identification and quantification of mechanical impacts and gap elimination processes. This results in insufficient comparability of test results across devices and batches, and makes it difficult to distinguish between abnormal device conditions and cable performance degradation, leading to inaccurate and inconsistent evaluation results.

Method used

By applying a constant monitoring current during the test, the current characteristics are monitored in real time and characteristic analysis is performed to identify the type of abnormality, correct the test results, and update the device configuration to reduce the impact of mechanical shock and electrical degradation, thus achieving an accurate assessment of torsional tensile performance.

Benefits of technology

It improves the accuracy and consistency of torsional tensile performance testing, reduces the difference in results between devices, enables timely identification of early cable failures, and enhances the reliability and comparability of test results.

Abstract

The application discloses a DC charging cable torsion tensile property test method and system, relates to the torsion tensile property test technical field, and the specific implementation scheme is: first, the measured DC charging cable is clamped and fixed on the target device, and the test configuration of the target device is initialized, on the basis, the torsion tensile property test process is started, in the test process, the running state of the constant monitoring current is determined on line, once the abnormal state of the current is identified, the abnormal type is immediately located through feature analysis, if no abnormality is detected, the current working condition is maintained to continuously monitor the torsion tensile property test process, so that the test severity and monitoring continuity are ensured; after the predetermined test is completed, the torsion tensile property test result of the DC charging cable is collected and corrected, so that the problems of insufficient torsion tensile property evaluation accuracy and poor comparability of results between different devices are reduced.
