1. A power transmission apparatus for inductive power transmission from a primary coil to a secondary coil, the apparatus comprising:
- a detector that is designed to detect an object in an interspace between the primary coil and the secondary coil and to output a detection signal;
an apparatus for introducing a disturbance that is designed to introduce a predetermined disturbance into the interspace between primary coil and secondary coil; and
a diagnosis apparatus that is designed to actuate the apparatus for introducing a disturbance, to receive the output detection signal from the detector and to determine a piece of diagnosis information using the received detection signal from the detector.

Abstract
The present invention relates to an inductive energy transfer system and a method for the diagnosis of a foreign object detection of an inductive energy transfer system. For this purpose, a defined fault is introduced into the region to-be-monitored between primary coil and secondary coil of the inductive energy transfer system, and the response of the foreign object detection to said defined fault is then evaluated.

8. A method for diagnosing an inductive power transmission system with foreign object monitoring, having the steps of:
-
introduction of a predetermined disturbance into a monitoring region of the foreign object monitoring; reception of a detection signal from the foreign object monitoring after the predetermined disturbance has been introduced into the monitoring region of the foreign object monitoring; and determination of a piece of diagnosis information using the received detection signal. - View Dependent Claims (9, 10)
