A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
UPower (previously DeviceKit-power) is a piece of middleware (an abstraction layer) for power management on Linux systems. [2] It enumerates power sources, maintains statistics and history data on them and notifies about status changes.
In 2006, Axeon, as a software company, began working with MPower, a manufacturer producing batteries for mobile phones and portable products. MPower was working on a battery to be used in electric vehicles and the Battery Management System, the software that monitors the lithium-ion cells, interfaces with the vehicle and ensures safety, was provided by Axeon.
Active-state power management (ASPM) is a power management mechanism for PCI Express devices to garner power savings while otherwise in a fully active state. Predominantly, this is achieved through active-state link power management; i.e., the PCI Express serial link is powered down when there is no traffic across it.

As stated before, the method by which the battery management system evaluates the SoH of a battery is arbitrary. Similarly, the SoH threshold below which an application deems a particular battery unsuitable is also arbitrary; a given application may accept a battery with a SoH of 50% and above, while a more critical application may only accept ...
Smart Battery System (SBS) is a specification for managing a smart battery, usually for a portable computer. It allows operating systems to perform power management operations via a smart battery charger based on remaining estimated run times by determining accurate state of charge readings. Through this communication, the system also controls ...
