CONTACTLESS ENERGY AND DATA TRANSMISSION DEVICE AND METHOD

The present invention relates to a device for the contactless energy and data transmission, having a primary unit provided with a primary inductor, and a secondary unit provided with a secondary inductor. The primary and secondary units are at least temporarily so relatively positioned that between the primary inductor and the secondary inductor a transformer coupling distance is formed. Furthermore, the primary unit is set up for the contactless transmission of energy to the secondary unit and the secondary unit is designed for supplying terminals connected thereto. The device is further developed in that the primary unit has means for interrupting the energy transmission across the transformer coupling distance in energy transmission intervals and the secondary unit has means for detecting the energy transmission intervals. Further, the secondary unit has means for transmitting data in the energy transmission intervals and/or the primary unit has means for transmitting data to the secondary unit. The invention also relates to a method for the contactless energy and data transmission.
