Abstract

A method is disclosed for charging at least one energy store of an electric vehicle via a charging point, using a first terminal having first connecting elements of a charging cable connected to the charging point. The first connecting elements are connected to corresponding second connecting elements of a second terminal on the vehicle, and the first and second connecting elements are designed to supply alternating current for charging the at least one energy store. Direct current from the charging point for charging the at least one energy store is supplied to the electric vehicle via at least two first connecting elements or at least two third connecting elements of the first terminal, wherein PLC communication between the electric vehicle and charging point in order to exchange information relating to the charging operation occurs via one or more first connecting elements on which no direct current for charging is carried.
