Latency-Based Energy Storage Device Selection

Abstract

Latency-based selections of energy storage devices are described herein. In implementations, latency behavior of computing tasks performed by a computing device is predicted for a period of time. Based on the predicted latency behavior of the computing device over the period of time, an assessment is made regarding which of multiple heterogeneous energy storage devices are most appropriate to service the system workload. For example, high energy density devices may be favored for latency sensitive tasks whereas high energy density devices may be favored when latency sensitivity is not a concern. A combination of energy storage devices to service the current workload is selected based upon the latency considerations and then power supply settings are adjusted to cause supply of power from the selected combination of energy storage devices during the time period.

What is claimed is: 
     
         1 . A method implemented by a computing device having multiple heterogeneous energy storage devices, the method comprising:
 predicting latency behavior of computing tasks performed via the computing device for a period of time;   selecting a combination of energy storage devices to use for performance of the computing tasks in dependence upon the predicted latency behavior; and   causing adjustments to switching hardware to supply power for performance of the computing tasks from the selected combination of energy storage devices during the period of time.
