Characteristics and Intelligent Diagnosis Analysis of Faults and Defects in Charging Facilities for New Energy Vehicles
The frequent malfunctions and defects of charging facilities for new energy vehicles have become a key factor restricting the development of the industry.These malfunctions not only affect the charging experience of car owners,but may also have adverse effects on the promotion and popularization of new energy vehicles.This study first conducted statistical analysis on the types of charging facility faults,and further clarified the fault modes and their impact on the system using FMEA analysis.Based on the Drools rule engine strategy,automatic detection and diagnosis of charging facility faults were achieved.The experimental results show that the system performs well in identifying key fault types such as input current overshoot of electrical modules and power supply module faults,with a diagnostic accuracy of up to 94.6%,and has good application prospects.
