Method for charging an electric vehicle by supplying DC over a cable configured for AC charging
First Claim
1. A method for charging at least one energy store of an electric vehicle by supplying direct current (DC) from a charging point over a charging cable configured for supplying alternating current (AC), the method comprising:
- connecting the electric vehicle to the charging point via the charging cable, the charging cable having a plurality of first AC-configured connecting elements that are (a) connected at a first end to the charging point and (b) connected at a second end to corresponding second connecting elements of a second terminal on the vehicle side, wherein the plurality of first AC-configured connecting elements comprise interfaces configured for connection to an alternating current source to supply alternating current for charging the at least one energy store of the vehicle,supplying direct current from the charging point for charging the at least one energy store to the electric vehicle via at least two of the first AC-configured connecting elements or at least two separate third connecting elements of the charging cable,during the supply of direct current from the charging point to the electric vehicle via the at least two first AC-configured connecting elements or the at least two third connecting elements, performing power line communication (PLC) between the electric vehicle and the charging point to exchange information relating to the charging operation via one or more of the first AC-configured connecting elements on which no alternating current or direct current for charging is being carried.

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.
