Method for establishing an IP-based communications connection between an electric vehicle and a charging control unit
First Claim
1. A method for establishing an IP-based communications connection between an electric vehicle and a charging control unit assigned to a charging station and allocated an IP address, the charging control unit and the charging station being part of a charging infrastructure, the electric vehicle being connected to the charging station via a charging cable and/or inductive charge coupling for charging and/or discharging an energy store of the electric vehicle, a first communications connection used solely by the electric vehicle and the charging station being provided via the charging cable and/or the inductive charge coupling, and the electric vehicle being able to communicate with the charging control unit and the charging infrastructure via a second communications connection used in a parallel manner by other electric vehicles and other charging control units, which comprises the steps of:
- a) providing the electric vehicle and the charging control unit with an identification via the first communications connection, the first communications connection only being used for a transfer of communications data only between the electric vehicle and the charging control unit;
b) allocating a further IP address to the electric vehicle; and
c) setting up an IP-based communication between the electric vehicle and the charging control unit via the second communications connection with an aid of the further IP address allocated to the electric vehicle and the identification provided via the first communications connection.

Abstract
A method establishes an IP-based communications connection between an electric vehicle and a charge control unit associated with a charging station assigned an IP address. The electric vehicle is connected to the charging station via a charging cable and/or an inductive charge coupling for charging and/or discharging. A first communication connection that can be used exclusively by the electric vehicle and the charging station is provided via the charging cable and/or the inductive charging coupling. The electric vehicle having the charging control unit and the charging infrastructure can communicate via a second communications connection that can be used in parallel by other electric vehicles and charge control units. An identification is provided to the electric vehicle and the charging control unit. An IP-based communication is established between the electric vehicle and the charging control unit, using the IP address.
