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.
This is because it is designed to use separate yet coupled circuits to approximate the lithium-ion diffusion in the electrode and electrolyte phases, heat transfer, and nonlinear voltage behavior in charging/discharging of a cell.
