Abstract: Wireless charging systems and methods for detecting foreign objects proximate the wireless charging systems. A wireless charging system (10) includes a wirelessly chargeable battery (14) that receives power from a wireless charging device (16) when the wirelessly chargeable battery (14) is proximate the wireless charging device (16). The wireless charging device (16) determines an actual electrical consumption of the wireless charging system (10), and the wirelessly charging battery (14) measures a voltage induced in the wirelessly chargeable battery (14) by the wireless charging device (16). The wireless charging device (16), the wirelessly chargeable battery (14), or a combination of the two determines an expected electrical consumption of the wireless charging system (10) based on the measured voltage, and determines whether a foreign object (12) is proximate the wireless charging system (10) based on the expected and actual electrical consumptions.

Abstract: An autoclavable container for sterilizing a wirelessly chargeable battery is disclosed. The autoclavable container includes a lid including metal and a base including a material permitting the transmission of an electromagnetic wave therethrough and having a glass transition temperature above 140 degrees Celsius. The lid defines a plurality of apertures configured to allow a sterilant to permeate the lid. The lid includes a mount configured to receive a filter defining a microbial barrier. The base defines a plurality of receptacles, each receptacle shaped to receive a wirelessly chargeable battery. The base also includes a plurality of protrusions, each protrusion being aligned with a corresponding receptacle.
