Abstract: In a wireless charging system, a power-transmitting node (TX), has a processor, a memory, a power transmitter for transmitting power wirelessly to a power-receiving node (RX), and a signal receiver for receiving signals from the RX. After the processor detects the presence of a foreign object (FO) during a power-transfer session, the processor places the TX in a protection state. The processor detects whether the FO has been removed using quality factor (QF) values for the TX that the processor measures before and after detecting the presence of the FO, and without requiring any QF values calibrated off-line. The QF values include a QF value measured before the FO is present, a QF value measured just after the TX enters the protection state, and a current QF value that is repeatedly updated as long as the TX remains in the protection state.

Abstract: In a wireless charging system, a power-transmitting node (TX) has a transmitter for transmitting power wirelessly to a power-receiving node (RX), and a signal receiver for receiving signals from the RX. During a power-transfer session, the TX accumulates data corresponding to its transmitted power level, detects an end of a received power (RP) packet from the RX, and then identifies a subset of the accumulated data. The TX calculates its transmitted power level using the subset of the accumulated data. The TX extracts a received power level of the RX from the received RP packet and compares its calculated transmitted power level with the RX's received power level to determine a presence of a foreign object. Accuracy of FO detection when packets from the RX are not properly received by the TX is improved.
