Zusammenfassung:	This disclosure provides systems, methods and apparatuses for a wireless power transmission apparatus to detect a fault of the wireless power reception apparatus. Various implementations relate generally to fault detection and mitigation in a wireless power system. In some aspects, a transmission (TX) controller of the wireless power transmission apparatus can detect a fault in the wireless power reception apparatus based on power transfer measurements or calculations in the wireless power transmission apparatus. The techniques may enable the wireless power transmission apparatus to detect faults such as an open circuit in the wireless power reception apparatus or a thermostat failure, among other examples. During the transmission of wireless power, the wireless power transmission apparatus may detect the fault and cease the transmission of wireless power.
