Wireless battery charging
First Claim
1. An apparatus for charging a battery in a portable device, the apparatus comprising:
- a non-power-line-connected source of electrical charge;
an intermediate storage device for storing an electrical charge;
a source charger/converter for charging the intermediate storage device with an electrical charge received from the non-power-line-connected source; and
a transfer charger/converter for delivering the stored electrical charge from the intermediate storage device to the battery in the portable device.

Abstract
Batteries in portable electrical or electronic devices are charged, through by a wireless battery charger, having an intermediate electrical energy storage device that is charged from a non-power line connected source, and discharged to recharge the battery of a portable device placed into a charge port of the wireless battery charger. The non-power line connected source may be a solar cell for converting light impinging on the solar cell into electrical energy. The non-power line connected source may also be a fuel cell for converting a fuel into electrical energy. The wireless battery charger may also include multiple sources, such as both a solar and a fuel cell. Charging the intermediate electrical energy storage device from the non-power line connected source may take place over an extended period of time having a duration longer than the time required to charge the battery of the portable device. The wireless battery charger and portable device may include transformer elements that allow the battery of the portable device to be re-charged by magnetic induction, without the need for electrical contacts in either the charger port or on the portable device.
