Systems, apparatus, and methods for quantifying power losses due to induction heating in wireless power receivers
First Claim
1. An apparatus for wireless power transfer, the apparatus comprising:
- a power transfer component configured to transmit wireless power to a wireless power receiver at a power level sufficient to charge or power a load;
a communications receiver configured to receive a message from the wireless power receiver, the message comprising a group identifier; and
a controller circuit operationally coupled to the power transfer component and the communications receiver 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 that are members of a group associated with the group identifier.

Abstract
Systems, methods and apparatus are disclosed for detecting power losses due to induction heating in wireless power receivers. In one aspect, an apparatus for wireless power transfer comprises a power transfer component configured to transmit wireless power to a wireless power receiver at a power level sufficient to charge or power a load. The apparatus further comprises a communications receiver configured to receive a message from the wireless power receiver, the message comprising a group identifier. The apparatus further comprises a controller circuit operationally coupled to the power transfer component and the communications receiver 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 that are members of a group associated with the group identifier.
