摘要： Systems, methods and apparatus are disclosed for detecting power losses due to induction heating in wireless power receivers (708). In one aspect, an apparatus for wireless power transfer (704) comprises a power transfer component (714) configured to transmit wireless power to a wireless power receiver (708) at a power level sufficient to charge or power a load. The apparatus further comprises a communications receiver (710) configured to receive a message from the wireless power receiver (708), the message comprising a group identifier. The apparatus further comprises a controller circuit (715) operationally coupled to the power transfer component (714) and the communications receiver (710) and configured to determine a power loss value based on the group identifier, the power loss value indicative of power loss due to induction heating presented by one or more wireless power receivers (708) that are members of a group associated with the group identifier.

摘要： An apparatus for receiving wireless power is provided. The apparatus a communication circuit configured to transmit a first indication of a first wireless charging category associated with the apparatus. The communication circuit is further configured to receive an indication of a wireless charging class of a power transmit unit (PTU). The communication circuit is further configured to transmit a second indication of a second wireless charging category associated with the apparatus based on the wireless charging class of the PTU being compatible with a higher wireless charging category than the first wireless charging category. The apparatus further comprises a coupler configured to receive a level of wireless power corresponding to the second wireless charging category. The higher wireless charging category indicates an ability to receive a greater amount of wireless power than the first wireless charging category.
摘要翻译：提供了一种用于接收无线电力的装置。该设备是被配置为发送与该设备相关联的第一无线充电类别的第一指示的通信电路。通信电路还被配置为接收功率发射单元（PTU）的无线充电类别的指示。通信电路还被配置为基于与第一无线充电类别相比更高的无线充电类别兼容的PTU的无线充电类别来发送与该装置相关联的第二无线充电类别的第二指示。该设备还包括耦合器，被配置为接收与第二无线充电类别对应的无线电力级别。较高的无线充电类别指示接收比第一无线充电类别更大量的无线电力的能力。

摘要： An apparatus and method for lost power detection are described. In one implementation, an apparatus for wireless transferring power comprises a wireless power transmitter configured to wirelessly transmit power at a power level sufficient to power or charge a chargeable device. The apparatus further comprises a controller configured to determine a first and second power difference between a first and second power measurement and the second and a third power measurement of the power level provided by the wireless power transmitter at a first, second, and third sample time, respectively. The controller is further configured to determine a transmitter power difference between the first power difference and the second power difference. The controller is further configured to determine an absence or a presence of an object that affects consumption of power transmitted by the wireless power transmitter based at least on the transmitter power difference Δ_T.
