With the popularity of electric vehicles,charging safety issues have become increasingly prominent.As a key component of the charging control guidance circuit,the reliability of vehicle relay directly affects the stability and safety of the charging process.In this paper,the reasons,detection methods and solutions of the relay adhesion fault in the guidance circuit of charging control of European standard electric vehicles are analyzed.By combining the test data and case analysis,an effective vehicle relay adhesion fault detection scheme is proposed,which can not only protect the vehicle from damage,but also significantly enhance the safety and reliability of electric vehicle charging system.
