Fault Tree Analysis of Vehicle Charging System

The composition and function of vehicle charging system are analyzed, and basic theory of fault tree analysis method is introduced. The qualitative analysis of its reliability is carried out. Fault tree model of vehicle charging system is built, the minimum cut sets are solved and the key parts are found out. Through quantitative analysis, the occurrence probability of top event and importance of bottom event are solved, which provides theoretical basis for fault diagnoses of vehicle charging system, saves time of fault diagnoses and reduces unnecessary disassembly.
