For the impact of today"s electric vehicle charging stations on the grid side of the power quality,especially electric vehicle batteries for automotive harmonic hazard during charging and the charging plug, pull occurred during voltage swells, dips and other issues.Designed with high precision meter chip ARM processor combines ATT7022C electrical parameter detection system,LabVIEW support for the analysis of power quality integrated platform.The results show that,this system is a comprehensive strong, can effectively detect the multiple parameters and change law of the harmonic wave in the power grid, power quality and battery charger for electric vehicle charging stations provide a basis for the selection and technical improvement.
