Abstract
A quality of charge (QoC) detector for use in inductive charging systems is disclosed. In an exemplary embodiment, an apparatus includes an inductor that receives a current signal to generate an electromagnetic field during a power transfer to an external device, and a quality detector to determine a quality metric associated with the power transfer. The apparatus also includes an indicator that indicates multiple states, where one of the multiple states is selected to indicate the quality metric.
