Abstract
Embodiments are directed to detecting and identifying a type of a wireless power device in a wireless power transfer field. According to one aspect, systems and methods are disclosed which describe limiting power transfer to non-compliant devices and detection of undesired power absorbers, such as metal objects, in a wireless power system. A method may include detecting one or more non-compliant devices and/or undesired wireless power absorbers positioned within a charging region of a wireless power transmitter. The method may further include limiting an amount of power transmitted by a transmitter in response to the detection, or reducing the amount of power received by the non-compliant device.
