Abstract: A charging system controls an optimum charging process of an at least partially electrically operated vehicle. The electrically operated vehicle has an energy accumulator. The charging system has at least one power source with which the energy accumulator is connected and can be charged, and at least one back end server which can automatically determine an optimum charging plan for charging the energy accumulator based at least on technical state data of the vehicle and an electricity rate that is assigned to the energy source. In this way, when the energy accumulator is connected to the power source, the technical state data of the vehicle is automatically transmitted to the back end server. After the back end server receives the technical status data of the vehicle, the back end server determines the optimum charging plan. The back end server can control the charging process of the energy accumulator according to the optimum charging plan.

Abstract: A communication module for an electrical charging process of a vehicle is provided. The vehicle communicates with a charging station via a charging cable using a first communication protocol, and the charging station is designed to communicate via the charging cable using a second communication protocol. The communication module is configured to receive charging station data from the charging station in accordance with the second communication protocol, and to send data corresponding to the charging station data to the vehicle, either using the first communication protocol if the first communication protocol allows the charging station data to be transmitted via the charging cable to the vehicle, or using a transmission medium such as a wireless connection to a user unit if the first communication protocol does not allow the charging station data to be transmitted to the vehicle over the charging cable.
