Insulation fault diagnosis and location research for electric vehicles

The high-voltage electrical safety of electric vehicles plays a crucial role in their reliability development process, insulation fault is an important indicator to measure the high-voltage electrical safety of electric vehicles. Currently, there is relatively little systematic research on insulation fault diagnosis and localization, in view of this, we have modeled various high-voltage modules of electric vehicles and constructed a system simulation platform using Simulink. Based on the simulation platform, an insulation fault data-set was constructed, and the effectiveness of the system was verified through machine learning methods, followed by diagnosis and localization of insulation faults.
