With the development of electric vehicle and the construction and the application of the large-scale Elec-tric Vehicle Charging Station ( EVCS ) , it’s becoming a gradually increasingly significant influence on the power quality of the smart grids for charging station’s heavy loaded charge and discharge. Based on the standard IEC61850,especially facing the methods and features of object-oriented modeling,combined with the technology of power quality monitoring devices of EVCS,this paper analysed the content of the standard IEC61850 applicable to EVCS,proposed new requirements of functional modules of power quality monitoring IED for EVCS,and built a new information model up to the IEC61850 standard. It guaranteed the information transmission of power quality monito-ring IED from EVCS in the smart grid is free,and provided necessary technical support for grasping the influence on the power quality of grids caused by the EVCS.
