Abstract

The invention relates to an inductive charging device for a vehicle and to a method for monitoring an inductive charging device for a vehicle, wherein a metal object is detected in each case. The method has the steps of: carrying out a passive metal object detection, MOD, while a battery of a vehicle (1) is inductively charged by generating an electromagnetic field in order to induce a charge current (I2) in a receiving coil structure (2) of the vehicle (1); and carrying out an active MOD at points in time at which no inductive charging process is being carried out.
