Abstract
Negotiating a power loss accounting profile (PLAP) for detecting a foreign object associated with wireless power transfer (WPT) from a wireless power transmitter (PTx) to a wireless power receiver (PRx) can include: receiving a request to operate according to a particular PLAP; providing one or more transmitter coefficients associated with a model corresponding to the particular PLAP; receiving one or more receiver coefficients associated with the model; receiving an indication of received power associated with the WPT; determining a measured power loss associated with the WPT by comparing the indication of received power from a transmitted wireless power; computing a predicted power loss based on the indication of received power, the one or more transmitter coefficients, the one or more receiver coefficients, and the model; and determining that a foreign object is present if the measured power loss exceeds the predicted power loss by more than a threshold.
