8. A method for charging a rechargeable battery in a system in which a wireless power transmitter and/or an external, wired power supply is respectively coupled to a wireless power receiver or a wired power receiver, comprising:
-
detecting states of power channels provided by the wireless power transmitter and/or an external, wired power supply by a signal detection means; determining whether each of the power channels is valid or not and determining a number of the valid channels by a controller; and when the number of valid channels is determined to be one, using the one valid power channel for supplying electric energy and, when the number of valid channels is determined to be two, using a first one of the power channels having been coupled to for supplying electric energy wherein the first one of the power channels having been coupled to is determined by comparing a time when the two power channels were coupled to. - View Dependent Claims (9, 10, 11, 12)
