The invention relates to an inductive charging device having at least one inductive charging coil wound about a coil axis, and an electric or dielectric antenna, which is arranged at a location that is shifted parallel to the coil axis in relation to a location of a region of the charging coil, a location within the at least one charging coil, or a location between the charging coils. The electric vehicle and the charging station each have such an inductive charging device. With the method, one or two such inductive charging devices are used, wherein by means of the inductive charging coils, energy is transmitted, and by means of the antennas, communications data are transmitted.
