Moreover, examples of equivalent circuit models of Lithium-ion batteries are covered. Equivalent circuit topolo-gies are introduced and compared according to the previously introduced criteria. An experimental sequence to model a 20Ah cell is presented and the results are used for the pur-poses of powerline communication.
Also known as “white”, “black” and “grey” boxes, respec-tively, the nature and characteristics of these model types are compared. Since the Li-ion battery cell is a thermo-electro-chemical system, the models are either in the thermal or in the electrochemical state-space.
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.
