Abstract: In recent years,with the rapid development of electronic information industry,relays have penetrated into all areas of production and life. At the same time,with the development of new energy electric vehicles,relays are also widely used in electric vehicle charging system design,and have become an indispensable switch control device in circuit design. By studying the driving principle of relays,starting from a safety perspective and combined with the failure mode analysis,the driving circuit of electric vehicle charging line relays is designed,and the relay fault detection method is described.

Key words: relay, drive, safety, circuit
