IEC 62368-1 Clause 9.6.2 Foreign Object Thermal Assessment Kit for Wireless Charging Systems

The LS-B29 Foreign Object Thermal Assessment Kit for Wireless Charging Systems evaluates temperature elevation in metallic foreign objects positioned on or adjacent to wireless power transmitter surfaces during operational conditions. This assessment mitigates burn hazards resulting from excessive thermal accumulation in metallic objects. During wireless power transmitter operation, alternating magnetic fields are generated. When metallic foreign objects are present within these fields, induced currents develop within the objects, with subsequent Joule heating effects causing temperature elevation. This test apparatus precisely monitors thermal variations in foreign objects across diverse operational parameters by simulating metallic object configurations encountered in practical application environments. This validation supports wireless power transmitter safety performance verification, ensuring operational safety by preventing hazardous thermal conditions in metallic objects, thereby facilitating safety engineering and quality assurance protocols for wireless charging devices.
