Accessory device for wireless charging and electronic device having the same
First Claim
1. An accessory device for being detachably mounted on an electronic device, the electronic device comprising a housing, the housing of the electronic device comprising a first face facing in a first direction, a second face facing a second direction that is opposite to the first direction, and a side face that at least partially encloses a space between the first face and the second face, the accessory device comprising:
- a housing comprising;
a first face facing the second face of the electronic device when the housing is mounted on the electronic device,a second face directed opposite to the first face, anda third face extending in the first direction from the first face so as to enclose at least a portion of the side face;
a battery positioned between the first face and the second face of the housing of the accessory device;
at least one conductive pattern electrically connected to the battery, and configured to transmit power from the battery to the electronic device in a wireless manner; and
a circuit electrically connected to the battery and the at least one conductive pattern,wherein, a substantially entire area of the first face and a substantially entire area of the third face of the housing of the accessory device comprise a non-conductive material, andwherein the circuit is configured to;
transmit power from the battery to the electronic device with a first frequency through the at least one conductive pattern, andtransmit information on a state of the accessory device through the at least one conductive pattern, with a second frequency which is changed from the first frequency.

Abstract
An apparatus and a method for wirelessly charging are disclosed. An accessory device is detachably mounted on an electronic device. The accessory device includes a housing including a first face configured to oppose a face of the electronic device when the housing is mounted on the electronic device, a second face opposite to the first face, and a third face extending in a first direction from the first face so as to enclose at least a portion of a side face. The accessory device further includes a battery and at least one conductive pattern electrically connected to the battery. The accessory device can transmit power to the electronic device in a wireless manner and/or receive power from an external device in a wireless manner. Areas of the first face and the third face of the housing of the accessory device are formed of a non-conductive material.
