Patent attributes
A system includes a power withdrawal point on a power supply network and a vehicle for the corded charging of a traction battery at the power withdrawal point. The vehicle includes a charging electronics unit for charging, and is electrically connectable to the vehicle-external power withdrawal point via a charging cable. The charging cable is configured as a cable connected outside the vehicle to a station charging device for a charging process, or as a cable charging device. The station charging device or the cable charging device, respectively, is electrically connected to the power withdrawal point when a charging connection has been established, and the power withdrawal point can supply an alternating current respectively via the station charging device or via the cable charging device for charging. The station charging device or the cable charging device, respectively, is electrically connected to the charging electronics unit via a pilot line when the charging connection has been established, where the charging process is controllable by an electric pilot signal applied via the pilot line. The charging electronics unit detects physical parameters of the pilot signal via the pilot line, physical parameters of the power supply network at the power withdrawal point via the charging current lines, and physical parameters of the station charging device or of the cable charging device via the pilot line, respectively, during a charging process so as to produce a parameter data set characterizing the power withdrawal point.
