Any wireless power transfer standard working within the 100 kHz to 350 kHz frequency range can be included in the scope of this document.
This document can be used for mobile wireless power transfer in mobile phones and other mobile devices, IoT devices, micro-sensor industries and related application fields.

IEC 63245-1:2021 specifies requirements for spatial wireless power transfer based on multiple magnetic resonances (SWPT-MMR), which is a non-radiative wireless power transfer (WPT). This document contains two categories of requirements: general requirements and functional requirements. The general requirements cover charging procedures and charging zones. The functional requirements cover each component of a SWPT-MMR system, such as transmitter coils.

IEC 63006:2019 specifies terminology and definitions related to wireless power transfer (WPT) technologies below 30 MHz to promote global harmonization of wireless power transfer terminology.
This document does not address terminology of wireless power transfer outside the scope of IEC TC 100 (Audio, video and multimedia systems and equipment), such as human exposure or safety.

IEC 63028:2017 defines technical requirements, behaviors and interfaces used for ensuring interoperability for flexibly coupled wireless power transfer (WPT) systems for AirFuel Resonant WPT. This document is based on AirFuel Wireless Power Transfer System Baseline System Specification (BSS) v1.3.

IEC 62827-2:2017, defines a wireless power management protocol for wireless power transfer to multiple devices in a wireless power management system. Various functions of wireless power management systems are justified. The wireless power management frames and messages that work between the management block of a power source and the management block or the coupler block of a device, or the coupler block of a power source, are defined as well to execute various functions. Also, the procedures for each functionality are described based on its frames and messages.

IEC 62827-3:2016 specifies methods and procedures to form groups for a spatial wireless power-transfer system. The group of spatial wireless power-transfer systems that include multiple power sources provides power transfer to receiving devices based on magnetic resonance technology. In order to achieve efficient power transfer to multiple receiving devices, this document also specifies methods and procedures to set, share, and control the conditions of power transfer between multiple power sources and receiving devices.

IEC 62827-1:2016 specifies common components of management for multiple sources and devices in a wireless power transfer system, and justifies various functions for wireless power transfer. This part of IEC 62827 defines the reference models for possible configurations of a wireless power transfer system. The models are specified in additional parts in more detail. This standard is applied to a wireless power transfer system for audio, video and multimedia equipment.

IEC/TR 62869:2013(E) addresses activities and considerations related to wireless power transfer for audio, video and multimedia systems and equipment. It combines public information, contributions by experts and completed IEC TC 100 WPT survey responses and reviews global market conditions. The TR describes a range of WPT technical approaches with the aid of a system reference model, outlines the impacts on WPT of applicable regulation and surveys standards development organization (SDO) and private industry consortium-led activities in support of WPT technical standards development. The TR concludes with observations and recommendations for potential future technical standards development activities that lie within scope of IEC TC 100.
