Sensor arrangement for provision of additional information in an inductive charging system

The invention relates to a sensor arrangement for the provision of additional information in an inductive charging system comprising a detection device (4) which is provided for detecting an electrically conductive foreign object, a monitoring apparatus (5), which for monitoring a relative position between a primary coil (2) and a secondary coil (3) is provided, and a communication unit (6). To minimize costs, space requirements and power consumption for the obligatory additive systems is proposed, the detection device (4), the monitoring device (5) and the communication unit (6) are integrated together to form a sensor assembly, said at least one module for common use is provided.
