To meet the demand of interconnection between off-board Charger and electric vehicles, this paper introduce inspection method and system solution of communication compliance test between off-board Charger and electric vehicles. According to the existing communication standards of electric vehicle charging system, integrated testing and evaluation for communication circuit performance, protocol conformance and communication failure response is completed. Meanwhile, this plan is able to independently achieve various parameters collection, analysis and display within charging communication environment. Through laboratory tests and charging station field test, the results showed that the proposed method could be made the comprehensive verification and analysis on the key communication performance index during the charging process. To improve the communication performance has a certain reference value.
