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).
Battery manufacturers may not refuse to take back waste batteries from end-consumers, irrespective of their chemical composition or origin (Art. 8(3)). Waste battery collection rate targets are specified in Article 10. Minimum targets of 25% of battery sales and 45% of battery sales by 26 September 2012 and 2016 respectively(Art. 10(2)).
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threaded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.
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 ...
