Power architecture for battery powered remote devices
First Claim
1. A power architecture, comprising:
- an information handling system comprising a main system load and battery and charging circuitry, said battery and charging circuitry including at least two first separate power sources comprising at least one main system battery, at least two second separate power sources and a main system power bus coupled to receive current from said at least two first separate power sources, said main system power bus being coupled to provide current to said main system load and to said at least two second separate power sources;
a wireless keyboard system comprising a remote system battery, a remote system load, and a remote system power bus, said wireless keyboard system being physically separable from said information handling system, and said wireless keyboard system being configured to be removably coupled to said battery and charging circuitry of said information handling system to allow said remote system power bus to receive current from said at least two second separate power sources of said battery and charging circuitry of said information handling system;
wherein said wireless keyboard system further comprises a remote system power bus configured to supply current to said remote system load, said remote system power bus being coupled to receive current from said remote system battery, and said remote system power bus being further configured to receive current from said at least two second separate power sources of said battery and charging circuitry of said information handling system when said wireless keyboard system is coupled to said information handling system.

Abstract
Systems and methods that may be employed to provide a high-reliability power architecture for an information handling system and a physically separable (i.e., detachable) remote system. The information handling system may be, for example, a portable information handling system such as a notebook computer. The remote system may be, for example, a battery-powered input or input/output device such as a wireless keyboard configured to wirelessly communicate input/output information with the information handling system, and that is also configured to be physically and electrically coupled to the information handling system to allow a flow of current to be provided from circuitry of the information handling system to circuitry of the remote system. The power architecture may be implemented using multiple (e.g., two) Uninterrupted Power System (UPS) buses.
