The invention relates to a method for establishing an IP-based communications connection between an electric vehicle (EV) and a charge control unit (CS1) associated with a charging station (EVSE1) and assigned an IP address (IP_EVSE1), wherein the charge control unit (CS1) and the charging station (EVSE1) are part of a charging infrastructure (CI) and the electric vehicle (EV) is connected to the charging station (EVSE1) via a charging cable and/or an inductive charge coupling for charging and/or discharging an energy store of the electric vehicle (EV). A first communication connection (CO1) that can be used exclusively by the electric vehicle (EV) and the charging station (EVSE1) is provided via the charging cable and/or the inductive charging coupling. The electric vehicle (EV) having the charging control unit (CS1) and the charging infrastructure (CI) can further communicate via a second communications connection (CO2) that can be used in parallel by other electric vehicles and charge control units (CS2). In the method according to the invention, an identification (TO_EVSE1, MAC_EVSE1, IP_EVSE1) is provided to the electric vehicle (EV) and the charging control unit (CS1) via the first communications connection (CO1). An IP address (IP_EV) is further assigned to the electric vehicle (EV). Subsequently, an IP-based communication is established between the electric vehicle (EV) and the charging control unit (CS1) by means of the second communications connection (CO2), using the IP address (IP_EV) assigned to the electric vehicle (EV) and the identification (TO_EVSE1, MAC_EVSE1, IP_EVSE1) provided by means of the first communications connection (CO1). |
