The equivalent circuit model of a Lithium-ion battery is a performance model that uses one or more parallel combinations of resistance, capacitance, and other circuit components to construct an electric circuit to replicate the dynamic properties of Lithium-ion batteries.
Existing electrical equivalent battery models The mathematical relationship between the elements of Lithium-ion batteries and their V-I characteristics, state of charge (SOC), internal resistance, operating cycles, and self-discharge is depicted in a Lithium-ion battery model.
1. Introduction For lithium-ion batteries, mathematical models not only constitute tools to estimate the performance of different battery components, as well as the cell or the battery pack, but also provide tools to strengthen the understanding of many physical properties, which determine the electrochemical response during the battery operation.
This paper presents a comparative study of twelve equivalent circuit models for Li-ion batteries. These twelve models were selected from state-of-the-art lumped models reported in the literature. The test data used is obtained from a battery test system with a climate chamber.
This study evaluates three different electrical-based models for lithium-ion batteries: Rint, 1RC, and 2RC models. Although there are other models, each with advantages and disadvantages, exploration and analysis using simulation techniques are performed to determine the most suitable model for a particular application.
A physics-based approach can instead be employed using the first principles-based lithium-ion battery model that was developed by Newman, Doyle and Fuller , and has been implemented into a number of commercial softwares, e.g. COMSOL Multiphysics.
