Wireless charger for mobile devices with flexible platform and method
First Claim
1. A wireless charger, comprising:
- an interface to an external power source;
a charging circuit coupled to receive power from the external power source through the interface, the charging circuit providing power to one or more power lines;
an energy storage device coupled to the charging circuit and the power lines;
a housing for the wireless charger for housing the charging circuit and the energy storage device; and
a flexible platform including a charging surface that is connected to the power lines, so as to allow the charging surface to receive power from either the charging circuit or the energy storage device, wherein the flexible platform has a first physical configuration, in which the charging surface is exposed for electrically coupling charging electrodes of a mobile device, and a second physical configuration in which the flexible platform is rolled up or folded to make more compact relative to the first physical configuration.

Abstract
A wireless charger and a method allow the wireless charger to have enhanced portability and a smaller footprint when not performing the charging function. The wireless charger includes a charging circuit providing power on one or more power lines, a housing for the wireless charger, and a flexible platform that includes a charging surface with two or more contact electrodes. The flexible platform may be unfolded or unrolled for charging a mobile device, and folded up or rolled up to achieve a smaller footprint, when not performing a charging operation. The wireless charger may further includes a data communication circuit for data communication between a power-line network and the mobile device.

21. A method for providing a wireless charger, comprising:
-
providing an interface to an external power source; coupling a charging circuit so as to receive power from the external power source through the interface, the charging circuit providing power to one or more power lines; coupling an energy storage device to the charging circuit and the power lines, so as to allow the power provided by the charging circuit to be stored in or discharged from the energy storage device; enclosing the charging circuit and the energy storage device in a housing for the wireless charger; and electrically connecting a flexible platform that includes a charging surface to the power lines, so as to allow the charging platform to receive power from either the energy storage device or the charging circuit, wherein the flexible platform has a first physical configuration, in which the charging surface is exposed for electrically coupling charging electrodes of a mobile device, and a second physical configuration, in which the flexible platform is rolled up or folded to make more compact relative to the first physical configuration. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
