Overview - IEC 63563-1:2025 (Qi Specification v2.0 - Part 1: Introduction)
IEC 63563-1:2025 is the International Electrotechnical Commission adoption of the Wireless Power Consortium’s Qi Specification version 2.0 - Part 1: Introduction. It formally introduces the Qi wireless power transfer system for flat-surface consumer devices (mobile phones, tablets) using up to 15 W of power. The document sets context, terminology and high‑level architecture for Qi-based charging and links the WPC specification to IEC standardization and conformity processes.
Key topics and technical requirements
- Scope and applicability: Targets flat-surface Power Transmitters (chargers) and Power Receivers (hand‑held devices) for up to 15 W; architectural notes reference an extended power profile limit (~30 W) for future designs.
- Wireless power fundamentals: Describes magnetic induction transfer between PTx (transmitter) and PRx (receiver) coils, and the lower magnetic coupling typical of Qi systems versus conventional transformers.
- Power levels and profiles: Defines the Qi power-level concept (fast charging up to 15 W in v2.0) and explains the role of power negotiation between transmitter and receiver.
- Operating frequency and coupling: Introduces frequency considerations and coupling coefficients that affect charging efficiency and coil design.
- Charging area and mechanical constraints: Covers charging-area expectations for flat-surface pads and embedded chargers (furniture, vehicles).
- Communication protocol: Explains the control and communication channel between PTx and PRx used to negotiate power, confirm charge capability, and provide optional location or ID services.
- Foreign object handling (FOH): Highlights safety measures for detecting metallic or hazardous foreign objects on the charging surface.
- Structure of the Qi Specification: Describes how the full specification is organized (this Part 1 is the introductory overview).
Practical applications and users
- Product designers & electrical engineers - use the standard to design compliant Qi transmitters and receivers (charging pads, smartphones, tablets, embedded chargers).
- OEMs and integrators - for embedding wireless charging into furniture, automotive interiors, appliances and public installations.
- Test labs & certification bodies - for conformity assessment and interoperability testing against Qi v2.0 behaviors described in the IEC adoption.
- Procurement & product managers - to specify interoperable wireless charging features in consumer electronics and public infrastructure.
