Receiver for wireless charging system for portable electronic device
First Claim
1. A cellular phone having a lower case, an upper case, a charging battery, a controller, a an NFC module, a circuit for communication, and a receiver which receives a wireless charging energy, transfers the charging energy to the charging battery,the receiver comprisesat least three coils which includes an NFC coil and a wireless charging coil;
- the wireless charging coil which receives the wireless charging energy and is provided in a separated space apart from the NFC coil,a first ferrite sheet which mounts the NFC coil;
a second ferrite sheet which mounts the wireless charging coil; and
an insulation film which wraps the wireless charging coil;
wherein the controller is connected to the wireless charging coil through a first connection line and the NFC module is connected to the NFC coil through a second connection line,wherein the first connection line and the second connection line are electrically separated each other and connected to the controller and to the NFC module respectively,and wherein an area where the wireless charging coil occupies is 20% to 80% of an area of the surface of the lower case.
