With this papers, the system procedure regarding the identification of the particular equivalent electrical circuit diagram of electrochemical cells is normally being given. Due to the fact that will energy storage systems (ESS) penetrate within many programs, the availability of their particular accurate and simple simulation models for time& amp; ndash; domain analysis is certainly very desirable. This papers describes the configuration of the laboratory measuring systems required for data exchange, curation, and analysis associated with received measured data required for development of equivalent electrical circuit models (EECM) associated with electrochemical cells. Nowadays, different types of electrochemical cells are available for product packaging technology. Therefore, the assessment of presented identification method is validated through measurements of two different forms of LiFePO4 cells. The particular first cell type can be prismatic labeled LFP040AHA, as well as the second type is NPB 60 AH of the particular same manufacturer. The primary aim of this paper is the determination from the elements of equivalent electric circuit schematics of chosen electrochemical cells. Consequently, the particular development of a simulation model is described, jointly with the evaluation of its accuracy through reviews with experimental measurements. Through achieved results, the relatives error of simulation model varies at 2%, and thus the presented methodology is suitable for recognition of EECM, and major design of accurate and fast computing simulation versions of ESS systems.
