Abstract

A wireless charging module includes an antenna and a wireless charger module. An enclosure is configured to fit at least partially within an optical drive bay of an information handling system. The antenna is disposed within a plastic lower portion of the enclosure. The plastic lower portion of the enclosure is configured to enable the antenna to wirelessly receive power from a wireless charging pad. The wireless charger module is disposed within the enclosure, and is configured to provide power to the information handling system.

Claims

1. A wireless charging module comprising:

an antenna disposed within a plastic lower portion of the wireless charging module, the plastic lower portion of the wireless charging module to enable the antenna to wirelessly receive power from a wireless charging pad, the wireless charging module to fit at least partially within an information handling system; and

a wireless charger disposed within the wireless charging module, the wireless charger to communicate with the antenna and with the information handling system, the wireless charger to determine whether the information handling system is in a bypass mode, to set a minimum power level for the information handling system in response to the information handling system being in the bypass mode, and to provide the minimum power level to the information handling system.

2. The wireless charging module of claim 1 further comprising:

a battery in communication with the wireless charger, the battery to store power received from the wireless charger.

3. The wireless charging module of claim 1 wherein the wireless charger is further to communicate information associated with the wireless charging module to the information handling system.

4. The wireless charging module of claim 1 wherein the wireless charger is further detect a presence of the wireless charging pad.

5. The wireless charging module of claim 1 further comprising:

a power connector to provide the power from the wireless charger to the information handling system.

6. The wireless charging module of claim 5 wherein the power connector is selected from a group consisting of a system management bus and a communication bus.

7. The wireless charging module of claim 5 wherein the power connector includes low power pins to drive power to logic components in the wireless charging module.

8. An information handling system comprising:

a wireless charging module to fit at least partially within the information handling system, the wireless charging module including;

an antenna disposed within a plastic lower portion of the wireless charging module, the plastic lower portion of the wireless charging module to enable the antenna to wirelessly receive power from a wireless charging pad; and

a wireless charger disposed within the wireless charging module, the wireless charger to communicate with the antenna, the wireless charger to provide power to the information handling system; and

a non-metallic section disposed within a metal lower portion of a body of the information handling system, wherein the non-metallic section is disposed below the antenna of the wireless charging module to enable the antenna to wirelessly receive power from the wireless charging pad.

9. The information handling system of claim 8 further comprising:

a battery in communication with the wireless charger, the battery to store power received from the wireless charger.

10. The information handling system of claim 8 wherein the wireless charger is further to communicate information associated with the wireless charging module to the information handling system.

11. The information handling system of claim 8 further comprising:
