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. It consists of a daemon (upowerd), an application programming interface and a set of command line tools.
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.
Ultium is characterized by a modular layout, using an Ultium battery to supply power to one or two Ultium Drive unit(s) using a common set of power electronics (charging, battery management system, and inverter). The high-voltage battery is composed of pouch cells that can be stacked horizontally or vertically, depending on the form factor ...
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 ...
Battery balancing and battery redistribution refer to techniques that improve the available capacity of a battery pack with multiple cells (usually in series) and increase each cell's longevity. [1] A battery balancer or battery regulator is an electrical device in a battery pack that performs battery balancing. [ 2 ]

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 ...
