ENERGY TRANSFER SYSTEM AND METHOD FOR THE DIAGNOSIS OF AN ENERGY TRANSFER SYSTEM

摘要

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.

主权项

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.
