摘要： 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.

摘要： This document describes techniques and apparatuses of load allocation for multi-battery devices. In some embodiments, these techniques and apparatuses determine an amount of load power that a multi-battery device consumes to operate. Respective efficiencies at which the device's multiple batteries are capable of providing power are also determined. A respective portion of load power is then drawn from each of the batteries based on their respective efficiencies.

摘要： A shared electrode battery includes multiple electrodes of one type (e.g., two or more cathodes) that share an electrode of another type (e.g., a shared anode). The multiple electrodes of the same type (e.g., the multiple cathodes) can have different characteristics, such as different chemistries, particle sizes and distributions, capacities, and so forth that are designed to provide particular features such as high energy density, high power density, high cycle life, fast charge, safety, and so forth. Multiple cathode-anode pairings of one of the multiple electrodes of the same type with the shared electrode are possible. Switching hardware is operable to select one of the multiple pairings at any given time, allowing the battery to provide power using the cathode having the desired characteristics at that given time. A single battery is thus able to provide these multiple different features.

摘要： Heterogeneous battery cell charging techniques are described for a device having a battery system with heterogeneous battery cells. A control system is provided that is configured to determine a charging strategy for charging the heterogeneous battery cells based upon an analysis of a plurality of contextual factors. For example, contextual factors may indicate anticipated future load conditions, battery usage preferences established for the battery system, and/or other factors indicative of an overall context in which charging occurs. Different charging strategies that indicate which battery cells to charge and the way in which charging is to be conducted may be mapped to different combinations of the contextual factors such that the charging is dynamically tailored to different contexts. A selected charging strategy is then employed to distribute charging current from a power source among the heterogeneous battery cells in the manner designated by the selected charging strategy.
