Abstract

A vehicle charging arrangement includes a charging station outside of a vehicle, a charging cable, and an electric charging unit of the vehicle. The charging station can be supplied with electric power from an external alternating-current network. The charging cable is electrically connected to the charging station or can be electrically connected to the charging station. The charging cable can be electrically connected to the electric charging unit by way of a plug-and-socket connection. The charging station has six electric taps, and the charging cable has six electric lines. In order to charge the electric energy storage device, the six electric taps of the charging station are connected in the same configuration with the six electric lines of the charging cable, and the six electric lines of the charging cable are connected in the same configuration with at least four electric contacts of the electric charging unit.
