Abstract: Methods and systems for controlling distribution of a main power supply and backup power supply can include detecting an output load on the main power supply from one or more electronic devices in excess of a threshold, which may correspond to a high efficiency band of the main power supply, and causing a backup power supply to provide an amount of supplemental power to the one or more electronic devices based in part on a difference between the output load and the threshold.

Abstract: Described herein is a smart battery unit capable of assessing its suitability to support a particular load. In some embodiments, the battery unit may receive an indication of power requirements for the particular load with respect to a period of time and may evaluate a total electrical capacity that would be required to support such a load based on those power requirements. The battery backup unit may monitor and dynamically update a full-charge capacity value related to its battery cells as well as the capacity requirement related to the load. The two values may then be compared to determine whether the battery backup unit is capable of supporting the load. If the full-charge capacity value is less than the capacity requirement for the load, then the battery unit may determine that it is not suitable for that load.
