Claim Text:
1. A power supply management method for the electronic device which can wirelessly receive electric power from a power supplying device having a plurality of electric power transmission parts each wirelessly transmitting electric power, comprising: an electric power transmission step of wirelessly transmitting electric power to the electronic device by the power supplying device; a step of receiving electric power transmitted from the power supplying device by the electronic device; a step of determining by the electronic device whether or not an amount of the electric power received from the power supplying device is equal to or larger than a threshold value necessary for activating a system of the electronic device; a system activation step of activating by the electronic device the system when the amount of the received electric power is equal to or larger than the threshold value; a non-operation state detection step of detecting, by the electronic device receiving electric power from the power supplying device, a non-operation state where no operation is performed with respect to the electronic device for a predetermined time period; a trigger information transmission step of, after detecting the non-operation state, transmitting by the electronic device to the power supplying device trigger information as a trigger for performing a control of reducing an amount of electric power supplied to the electronic device; a transmission electric power amount control step of reducing by the power supplying device an amount of electric power transmitted to the electronic device according to the trigger information; and a step of outputting confirmation information for confirming whether or not the system of the electronic device may be shut-down by the electronic device when the non-operation state is detected, wherein in the trigger information transmission step, the trigger information is transmitted to the power supplying device when information permitting shutdown of the system is inputted according to the confirmation information, and in the transmission electric power amount control step, transmission of electric power is stopped by the power supplying device to the electronic device according to the trigger information.
