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 SoH, and SoC), [1] calculating secondary data, reporting that data, controlling its environment, authenticating or balancing it.

A notification LED on a smartphone. A Notification LED is a small RGB or monochrome LED light usually present on the front-facing screen bezel (display side) of smartphones and feature phones whose purpose is to blink or pulse to notify the phone user of missed calls, incoming SMS messages, notifications from other apps, low battery warning, etc., and optionally to facilitate locating the ...
the fraction of the battery's capacity which is currently removed from the battery with regard to its (fully) charged state. For fully charged batteries, the depth of discharge is connected to the state of charge by the simple formula. D o D = 1 − S o C {\displaystyle \mathrm {DoD} =1-\mathrm {SoC} } The depth of discharge then is the ...
Wear OS (also known simply as Wear[8] and formerly Android Wear[9]) is a version of Google 's Android operating system designed for smartwatches and other wearables. [10][11][12] By pairing with mobile phones running Android version 6.0 "Marshmallow" or newer, or iOS version 10.0 or newer with limited support from Google's pairing application ...
Battery indicator. A battery indicator (also known as a battery gauge) is a device which gives information about a battery. This will usually be a visual indication of the battery's state of charge. It is particularly important in the case of a battery electric vehicle.

State of health. State of health (SoH) is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions. The unit of SoH is percent (100% = the battery's conditions match the battery's specifications). For example, when the capacity of a new battery is same as the nominal capacity as per the ...
Battery charger. Charging a 12 V lead–acid car battery. A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [1][2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage, current, for how long and what to do when ...
