This paper presented basic functions and working princenples of control pilot circuit for charging coupler, designed a test method of matching resistance and voltage status for various measuring locations under different charging types. Confirmation of connection status for charging coupler,inspections of variation on power output capacity and execution behavior for charging stop under a normal or abnormal conditions as well as sequence of control at different charging stage were realized. Expermental results indicated that proposed test method is effective and practical for function measuring of control pilot circuit for the charging couplers.
