【Abstract】Inthedevelopmentof theelectric vehicle industry，thevehicle-to-external discharge functionisof great significance.However，theimplementationof theexistingcharginganddischarging standardshasproblemssuchas the lackofreverse discharge function，failure toconsider sleepwake-upand electromagneticcompatibility interference，etc. Therefore，a V2Xchargingand discharging guidance circuit isdesigned.Theresearch elaborates indetail thecircuit principlesand working processs suchas thepower supply signal and the charging gun interface in thecircuit.This circuitcanfillthegapof thestandard circuitforexternaldischargeofelectricvehicles，standardizethedischargemode andsafetyrequirements，andachievetheexternaltransmissonofelectricalenergyonthebasisofretainingtheoriginal chargingfunction.Itismainlyachieved throughsoftwareandcontrollogicupgrades，withasmallincreaseinhardware costs，whichcanefectivelyreducesocial costsandhassignificant valueforpromoting thedevelopmentof theelectric vehicle industry.
