Technical Field

[0001] The present invention belongs to the technical field of virtual simulation testing of battery swap stations, and in particular relates to a virtual simulation system and method for automated testing of battery swap stations. Background Art

[0002] Battery swap stations are energy stations that provide charging and rapid battery replacement for electric vehicles. When charging batteries at battery swap stations, various charging anomalies may occur due to various complex reasons. Prolonged abnormal charging conditions can lead to serious hazards such as fire and explosion.

[0003] Existing battery swap stations often have charging detection systems to detect charging anomalies and prevent serious damage caused by prolonged abnormal charging. However, in actual use, the reliability of the charging detection system is crucial to avoiding charging-related hazards. Currently, there is no device for testing the reliability of charging detection systems. Therefore, providing virtual simulation tests for charging detection systems to evaluate their reliability is a worthy research issue. Summary of the Invention

[0034] In fact, when the graphic simulation unit detects the simulation detection instruction transmitted by the analog simulation module, the graphic simulation unit intercepts the voltage-time diagram and the current-time diagram within the detection interval T from the current moment and transmits them to the abnormal analysis unit; the abnormal analysis unit compares the voltage-time diagram, the current-time diagram and the abnormal model library to obtain the state analysis result; when the graphic similarity between the voltage-time diagram and the current-time diagram and any abnormal model in the abnormal model library is greater than or equal to the similarity threshold P, the abnormal analysis unit judges it as an abnormal result corresponding to the abnormal model, that is, the abnormal result is the corresponding abnormal model, otherwise, the abnormal result is that there is no abnormality.

[0035] At the same time, after the simulation module issues a simulation detection instruction, it transmits the charging position test information to the comparison and statistics unit; the abnormality analysis unit transmits the abnormal result corresponding to the charging position test information to the comparison and statistics unit; the comparison and statistics unit compares the charging position test information with the abnormal result to determine whether the detection is successful or failed, and counts the number of successful detections and then analyzes to obtain a reliable detection report; specifically, if the abnormality set in the charging position test information corresponds to the abnormal result, the detection is successful, otherwise the detection fails.
