【Abstract】New energy vehicle charging systems are increasingly exposed to harsh environments—intense heat，depcold，highhumidity，andelectromagneticinterference—allofwhichcompromisesystemstabilityand reliability.This study centerson the charging system itself，dissecting its most vulnerable failure paterns under such complex conditions.A multi-dimensional diagnostic framework isdeveloped，integrating real-time sensor monitoring， physical system modeling，and AI-driven fault prediction.Building on these foundations，the paper proposes asuite of targeted strategies，including fault tolerance design，communication protocol redundancy，andadaptive environmental hardenig.Experimentalresultsdemonstratethat the proposed framework significantly improves earlyfault detection andsystemself-recovery，offring critical technical assurance forsafeandresilient charging in extreme scenarios.
