METHOD OF PROVIDING GUIDE INFORMATION RELATED TO A WIRELESS CHARGING BY A WIRELESS POWER TRANSFER SYSTEM

摘要

The present invention has an advantage capable of providing a wireless charging system (or wireless power transmission system) which effectively stably transmits and receives wireless power by providing guide information regarding the wireless charging to a user of multiple wireless power receivers through one among the multiple wireless power receivers (multiple receiving devices or multiple nodes). The multiple wireless power receivers exist on a communication zone and a charging zone. The communication zone and the charging zone are classified on a wireless power transmission device or a wireless power transmission network. For this, a guide information providing method according to an embodiment disclosed in the specification transmits and receives a packet including a variety of information for receiving the wireless power with the wireless power transmission device on a wireless power network based on magnetic field communication. The guide information providing method by a wireless power receiving device which charges power by receiving a wireless power signal produced from the wireless power transmission device comprises; a step of determining whether the magnetic field communication is normally executed with the wireless power transmission device or not; a step of receiving the wireless power signal from the wireless power transmission device if the magnetic field communication is normally executed; a step of determining whether the wireless power is normally charged based on the received wireless power signal or not; and a step of providing guide information regarding the wireless power charging if the wireless power is normally not charged.
