CORRECTED VERSION 2026-03 IEC 63563-6:2025 defines the messaging between a Power Transmitter and a Power Receiver. The primary purpose of this messaging is to set up and control the power transfer. As a secondary purpose, it provides a transport mechanism for higher-level applications such as Authentication. The communications protocol comprises both the required order and timing relations of successive messages. This corrected version of IEC 63563-6:2025 incorporates the following correction: - correction of the publication date on the cover page.

Overview

IEC 63563-6:2025 - Qi Specification version 2.0 – Part 6: Communications Protocol defines the messaging between a Power Transmitter and a Power Receiver for wireless power transfer. Its primary purpose is the setup and control of power delivery; as a secondary function it provides a transport mechanism for higher‑level applications such as Authentication and device identification. The standard specifies the required message types, sequencing, timing relations and state diagrams that ensure reliable, interoperable wireless charging under the Qi v2.0 ecosystem.

Key topics and technical requirements

Protocol phases: Detailed phases including Ping, Configuration, Negotiation and Power Transfer. Each phase has defined states, message flows and timing constraints.

Power Transfer Contract: Rules for negotiating and updating contract elements (e.g., power profiles and permitted operating parameters) between transmitter and receiver.

Data packet types and headers: Definitions for numerous packet types used during communication - e.g., ADC (Auxiliary Data Control), ADT (Auxiliary Data Transport), CHS (Charge Status), CFG (Configuration), CE (Control Error), EPT (End Power Transfer), XID (Extended Identification), FOD (Foreign Object Detection) and others - including when and how they are used.

State diagrams and timing: Prescribed state diagrams and explicit timing relations for message ordering, retries and timeouts to guarantee deterministic behavior.

Data transport streams & higher‑level apps: Mechanisms for transporting larger or higher‑level payloads (authentication tokens, identification data, NFC tag protection) over the established communications link.

Safety and integrity features: Support for Foreign Object Detection (FOD) reporting and negotiated hold‑offs, aiding safe operation and device protection.

Backward compatibility & conformance: Provisions to maintain interoperability with earlier Qi implementations and guidance for compliance testing and certification.

Practical applications - who uses this standard

Hardware and firmware engineers designing Qi‑compliant power transmitters, receiver coils and control electronics.

Embedded systems developers implementing message parsing, state machines and timing logic for wireless chargers or mobile devices.

Test labs and certification bodies validating interoperability, timing, FOD behavior and message conformance per IEC 63563‑6:2025.

Product managers and integrators ensuring devices meet Qi v2.0 communications requirements for consumer electronics, wearables, automotive wireless charging and IoT charging surfaces.

Security and application developers leveraging the communications transport for authentication, device identity and NFC tag protection.

Related standards and references

Part of the IEC 63563 series based on the Wireless Power Consortium’s Qi Specification v2.0; implementers should consult the other Qi parts (identification, power profiles, interoperability tests) and the IEC/ISO directives referenced in the document for full compliance and conformance requirements.
