Abstract

A device for transmitting data between a data transmission device of a vehicle and a data transmission device of a communications network, as part of a charging process of an electrical energy store of the vehicle, is disclosed. The vehicle data transmission device is based on a first communications protocol with a first signal level, while the communications network data transmission device is based on a second communications protocol with a second signal level. The device includes a signal-matching device having at least one first coupling transformer, which couples a data transmission device of a charging station to the data transmission devices of the vehicle and of the communications network via respective coils. The signal-matching device is configured to match the first signal level to the second signal level and vice versa.
