Title:
MANAGEMENT PROTOCOL OF WIRELESS POWER TRANSFER FOR MULTI-DEVICES
Document Type and Number:
WIPO Patent Application WO/2014/104429
Kind Code:
A1
Abstract:
This disclosure defines the interface for wireless power transfer to multiple devices (including one device) that require charging within several meters. In order to provide WPT for multi-devices, functionalities, system structure, primitives, frame format, and procedures are defined. This standard selectively utilizes various frequency bandwidths ranging from the low frequency of 50 kHz to the high frequency of 15 MHz for wireless power transfer. For system control, it requires supports of the signalling by which data and control signals can be exchanged. This standard can be applied to a multimedia industrial field for use of batteries such as mobile terminals, laptops, portable multimedia players, etc.
