This Recommendation defines a framework for wireless power transmission (WPT) application service.

WPT is a technology to transmit electric power wirelessly. WPT can be realized in various ways, and applications using WPT technology are expanding to mobile and portable devices, home appliances and office equipment, and electric vehicles. In particular, WPT technology is useful in providing electric power to the Internet of things (IoT) devices in constrained environments.

The WPT application service is an application service to realize various types of WPT charging for devices (IoT devices in the context of this Recommendation) capable of receiving electric power wirelessly.

The scope of this Recommendation includes the following:

– concept of WPT application service;

– functional model of WPT application service;

– requirements of the WPT application service;

– basic service flows for WPT application service.

Use cases of WPT application service are also provided in Appendix I.

NOTE – Electric hazard related issues are out of scope of this Recommendation.
