Abstract
Official abstract text for this publication.
A wireless power transfer system for a vehicle door glass includes: a door glass having an electric load, and a pair of electrodes connected to the electric load; a power transmitter mounted in a vehicle door, and wirelessly transmitting power of a battery; and a power receiver embedded in the door glass, and wirelessly receiving the power from the power transmitter, wherein the power receiver applies the power received from the power transmitter to the pair of electrodes of the door glass.
First claim
Opening claim text (preview).
What is claimed is: 1. A wireless power transfer system for a vehicle door glass, the wireless power transfer system comprising: a door glass having an electric load, and a pair of electrodes connected to the electric load; a power transmitter mounted in a vehicle door, and including a transmitting coil wirelessly transmitting power of a battery; and a power receiver embedded in the door glass, and including a receiving coil wirelessly receiving the power from the power transmitter, wherein the power receiver applies the power received from the power transmitter to the pair of electrodes of the door glass, wherein the door glass has an outdoor glass layer facing an outside of the vehicle, and an indoor glass layer facing an interior of the vehicle, and wherein the receiving coil is a thin film attached to at least one of the outdoor glass layer or the indoor glass layer by an adhesive layer. 2. The wireless power transfer system according to claim 1 , wherein the transmitting coil wirelessly transmits alternating current (AC) power, and wherein the receiving coil wirelessly receives the AC power from the transmitting coil. 3. The wireless power transfer system according to claim 2 , wherein the electric load is interposed between the outdoor glass layer and the indoor glass layer. 4. The wireless power transfer system according to claim 2 , wherein the power transmitter further includes: a converter converting direct current (DC) power to AC power; and a transmitter controller controlling a power level to be output from the converter. 5. The wireless power transfer system according to claim 1 , wherein the receiving coil is interposed between the outdoor glass layer and the indoor glass layer. 6. The wireless power transfer system according to claim 1 , wherein the power receiver is embedded in a bottom end portion of the door glass. 7. A wireless power transfer system for a vehicle door glass, the wireless power transfer system comprising: a door glass having an electric load, and a pair of electrodes connected to the electric load; a power transmitter mounted in a vehicle door, and including a transmitting coil wirelessly transmitting power of a battery; and a power receiver embedded in the door glass, and including a receiving coil wirelessly receiving the power from the power transmitter, wherein the power receiver applies the power received from the power transmitter to the pair of electrodes of the door glass, wherein the door glass has an outdoor glass layer facing an outside of the vehicle, and an indoor glass layer facing an interior of the vehicle and, wherein the receiving coil is patterned on at least one of the outdoor glass layer or the indoor glass layer by a patterning process. 8. The wireless power transfer system according to claim 7 , wherein the patterning process includes photolithography consisting of deposition, exposure, and development, and etching. 9. The wireless power transfer system according to claim 7 , wherein the transmitting coil wirelessly transmits alternating current (AC) power, and wherein the receiving coil wirelessly receives the AC power from the transmitting coil. 10. The wireless power transfer system according to claim 7 , wherein the electric load is interposed between the outdoor glass layer and the indoor glass layer. 11. The wireless power transfer system according to claim 7 , wherein the receiving coil is interposed between the outdoor glass layer and the indoor glass layer.
