Summary:The present specification relates to a method for controlling power for fast charging in a wireless power transmission system, in which, in the transfer phase, a wireless power receiver receives a power information packet from a wireless power transmitter. The wireless power receiver transmits a response message to the power information packet to the wireless power transmitter. If the wireless power receiver does not satisfy a required value for power information of the wireless power transmitter, the response message includes DSR/NAK and the reason for DSR/NAK. Power is controlled on the basis of the reason for DSR/NAK. La présente spécification concerne un procédé de commande de puissance pour une charge rapide dans un système de transmission de puissance sans fil, dans lequel, durant la phase de transfert, un récepteur de puissance sans fil reçoit un paquet d'informations de puissance en provenance d'un émetteur de puissance sans fil. Le récepteur de puissance sans fil transmet un message de réponse au paquet d'informations de puissance de l'émetteur de puissance sans fil. Si le récepteur de puissance sans fil ne satisfait pas une valeur requise pour des informations de puissance de l'émetteur de puissance sans fil, le message de réponse comprend DSR/NAK et la raison de DSR/NAK. La puissance est commandée sur la base de la raison de DSR/NAK. 본 명세서(present disclosure)는 무선 전력 전송 시스템에서 고속 충전을 위한 전력제어를 수행하는 방법에 있어서, 전달 페이즈에서, 무선 전력 수신기는 무선 전력 전송기로부터, 전력 정보 패킷을 수신한다. 무선 전력 수신기는 무선 전력 전송기에게, 전력 정보 패킷에 대한 응답 메시지를 전송한다. 무선 전력 수신기는 무선 전력 전송기의 전력 정보가 요구되는 값을 만족하지 못하면, 응답 메시지는 DSR/NAK 및 DSR/NAK에 대한 이유를 포함한다. DSR/NAK에 대한 이유를 기반으로 전력 제어가 수행된다.
