Full title and description

IEC 63563-7:2025 — Qi Specification version 2.0, Part 7: Foreign Object Detection. This International Standard specifies methods and requirements to detect and mitigate foreign (typically metallic) objects in the magnetic field of a wireless Power Transmitter so that power transfer proceeds safely without hazardous heating of objects. Some detection methods may require cooperation from the Power Receiver and include measurement, detection-limit criteria and required actions when a foreign object is detected.

Abstract

Defines technical methods, test procedures and conformance criteria for Foreign Object Detection (FOD) within the Qi Specification v2.0 ecosystem. The document establishes detection strategies, measurement setups, thresholds, verification tests and recommended responses to detected objects to prevent unsafe heating and ensure interoperability between transmitters and receivers. The standard is intended to be used alone or as part of the broader IEC 63563 series.

Scope

Specifies methods to detect foreign objects (primarily metallic) in or near the magnetic coupling region of a wireless power transmitter and to ensure the power transfer either does not occur or is limited so that metal objects do not heat to unsafe temperatures. The scope covers detection principles, required instrumentation and test arrangements, detection thresholds and required transmitter/receiver behaviors when foreign objects are present. Normative and informative annexes provide test examples and recommended verification procedures for manufacturers and test labs.

Key topics and requirements

• Definitions and terminology specific to foreign object detection in Qi v2.0 systems.
• Detection methods and measurement techniques (e.g., magnetic-field sensing, temperature monitoring, impedance variation, calibrated test objects).
• Performance criteria and detection thresholds that determine safe operation or required shut-down/derating actions.
• Test arrangements, instrumentation, and repeatable test procedures for laboratory verification.
• Receiver/Transmitter interactions and required communication or signaling to support FOD where applicable.
• Conformance and marking guidance to demonstrate compliance with FOD requirements.

Typical use and users

Primary users include wireless power transmitter and receiver manufacturers, conformity assessment bodies, test laboratories, product safety engineers and system integrators working with Qi wireless power systems. The standard is used during design, pre‑compliance testing, product certification and in technical due‑diligence for product development and regulatory submissions.
