Energy transmission device
First Claim
1. An energy transmission device comprising:
- a.) a primary side including a primary coil;
b.) a detachable secondary component including a secondary coil, the primary coil being operable to inductively transmit electromagnetic energy to the secondary coil with such transmitted electromagnetic energy being characterized by an energy transmission frequency; and
c.) a sensing means provided to the primary side for detecting at least one characteristic value of the detachable secondary component, the sensing means coupling a measurement voltage with a measurement frequency transmitted from the primary side to the secondary side that differs from the energy transmission frequency transmitted into the secondary coil by the primary coil.

Abstract
The invention relates to an energy transmission device having a primary coil for transmitting to a detachable secondary coil electromagnetic energy by induction with the electromagnetic energy being characterized by an energy transmission frequency and sensing component for detecting at least one characteristic variable of a detachable secondary end including the secondary coil. The sensing component is adapted to detect information on the presence of a detachable secondary end in an especially reliable manner. For this purpose, the sensing component couples a measuring voltage having a measuring frequency that is different from the energy transmission frequency into the secondary coil.
