Possible applications of models are the optimization of battery management, i.a. cell scheduling al-gorithms and the shaping of the discharge profile of the bat-tery under performance constraints. This enables the maxi-mization of the battery life time by trading off performance using information about the State of Charge (SoC).
In the context of electrical engineering and for the spe-cial purpose of battery management and monitoring, abstract models taking the form of equivalent circuits are a popular and valid choice. Also, a trade-off between the complexity of the equivalent circuit (mainly the number of RC elements) and its accuracy should be accepted.
