Abstract: Techniques are described for battery management in a computing device. The described techniques may be implemented by a battery offline module that provides functionality to control utilization of a battery such as determining whether the battery is available to receive power from a power source. For instance, the battery offline module may receive an input requesting that a battery be taken offline, determine whether system conditions for taking the battery offline are met, and take the battery offline when the system conditions are met such that the battery is not capable of receiving power from a power source of the computing device. In some instances, the battery offline module may cause different powering and charging arrangements between multiple batteries of the computing device. By implementing the battery offline module in the computing device, battery utilization is controlled to improve battery life.

Abstract: Techniques for battery management of a device having multiple batteries are described herein. In one or more implementations, management for increased battery reliability involves assessing a combination of factors that influence a control policy for multiple batteries in a battery system. Based on the assessment, values of control parameters for power management of the battery system are set to reflect a tradeoff between performance and reliability. Then, at least one of battery utilization or charge current distribution is controlled in dependence upon the values that are set. Control of the battery system can be based in part upon differences in cycle counts for multiple batteries of a battery system for a device, such that cycle counts of the multiple batteries are managed for improved reliability.

Abstract: Techniques for a battery protection mode are described. According to techniques described herein, an electronic device can operate in a standard charging mode where a battery of the device is permitted to be charged to full capacity. However, when a trigger event occurs, the electronic device transitions to a battery protection mode where a maximum permitted charge for the battery is reduced from the standard charging mode.

Abstract: A method of analysis of a time interval between two selected measurement edges of interest includes locking a plurality of at least three substantially interchangeable oscillators to a common reference frequency, the oscillators containing digital locked-loop (DLL) circuit architecture. The method includes operating one oscillator as a timebase oscillator, and operating the other oscillators as edge-resettable measurement oscillators. The method further includes coupling one oscillator with a switched and physically-immutable parametric variation, producing an offset in the frequency of the coupled oscillator relative to the frequency of the other oscillators.
