Household appliance, system and method for operating

Abstract

Household appliance (1) comprising a power coil (2) for the inductive transmission of energy to a receiving device (51) of a power receiver (50), a communication device (3) comprising a communication coil (4) for communication with the power receiver (50), and a control device (5), wherein the power coil (2) has a maximum power output. The control device (5) is suitable and configured to limit the actually usable power transmitted via the power coil (2) to a predetermined, reduced maximum power output for the power receiver (50) identified by means of the communication device (3), and / or to release the maximum actually usable power of the power coil (2).The system according to the invention comprises such a household appliance (1) and a power receiver (50) comprising a receiving device (51) for receiving power and a communication coil (52). In the method for operating such a system (100), the actually usable power of the power coil (2) of the household appliance (1) is limited to a predetermined reduced maximum power for the identified power receiver (50) and / or the actually usable power of the power coil (2) is released to the maximum extent.
