Abstract

A method for supplying a number of electric charging stations with electricity, wherein AC voltage provided by an electricity source is transformed into a prescribed AC voltage level by at least one transformer via at least one star winding and at least one delta winding and subsequently routed via AC voltage lines to the number of electric charging stations and converted directly to direct current in respective charging stations from the number of electric charging stations locally by at least two rectifiers of the charging stations.
