Abstract: An induction energy transmission system includes a supply unit having a supply induction element to inductively provide energy in an operating state. A receiving unit receives at least part of the energy provided by the supply induction element in the operating state. A sensor unit detects a measurement variable and a first information channel transmits a first signal between the receiving unit and the supply unit, with the first signal coding the measurement variable. A second information channel which differs from the first information channel transmits a second signal between the receiving unit and the supply unit, with the second signal coding the measurement variable.
