Evaluation of the Accuracy of the Identified Equivalent Electrical Circuit of LiPePO4 Battery through Verified Measurements

In this paper, the system procedure for identification of equivalent electrical circuit diagram electrochemical cells is being given. Due to fact that energy storage systems (ESS) penetrate within many applications, availability their accurate and simple simulation models time–domain analysis very desirable. This paper describes configuration laboratory measuring required data acquisition, curation, received measured development (EECM) cells. Nowadays, various types are available packaging technology. Therefore, evaluation presented methodology validated through measurements two different LiFePO4 The first cell type prismatic labeled LFP040AHA, second NPB 60 AH same manufacturer. main aim determination elements schematics selected Consequently, a model described, together with its accuracy comparisons experimental measurements. From achieved results, relative error varies at 2%, thus suitable EECM, consequent design fast computing ESS systems.
