Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is removed from the charged battery on a regular basis.
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.
Number of charge–discharge cycles; Age of the battery; Temperature of battery during its previous uses; Total energy charged and discharged; In addition, the designer of the battery management system defines an arbitrary weight for each of the parameter's contribution to the SoH value. The definition of how SoH is evaluated can be a trade secret.
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.

Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles ...
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
A lithium primary battery, not interchangeable with zinc types. A rechargeable lithium-ion version is available in the same size and is interchangeable in some uses. According to consumer packaging, replaces (BR) 2 ⁄ 3 A. In Switzerland as of 2008, these batteries accounted for 16% of lithium camera battery sales. [75]
The biggest disadvantage of the current lithium metal battery (as of 2024) is that the maximum discharge current is a paltry 0.2% of the capacity. That is for a 5 mAh battery (a typical current size), the maximum discharge current is just 10 μA. [13] The battery's charging requirements are also very different to the lithium ion type.
