Equivalent Circuit Model For Li-ion Cells
The equivalent circuit model (ECM) is a common lumped-element model for Lithium-ion battery cells. The ECM Simulation, simulates the terminal voltage dynamics of a Li-ion cell through an Equivalent circuit, equivalent electrical network composed passive elements, such as resistors and capacitors, and a Voltage source, voltage generator. The ECM is widely employed in several application fields, including Computer simulation, computerized simulation, because of its simplicity, its low computational demand, its ease of characterization, and its structural flexibility. These features make the ECM suitable for real-time Battery management system, Battery Management System (BMS) tasks like state of charge (SoC) estimation, State of Health (SoH) monitoring and battery thermal management. Model structure The equivalent-circuit model is used to simulate the voltage at the cell terminals when an electric current is applied to discharge or recharge it.

Lumped-element Model
The lumped-element model (also called lumped-parameter model, or lumped-component model) is a simplified representation of a physical system or circuit that assumes all components are concentrated at a single point and their behavior can be described by idealized mathematical models. The lumped-element model simplifies the system or circuit behavior description into a topology. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc. This is in contrast to distributed parameter systems or models in which the behaviour is distributed spatially and cannot be considered as localized into discrete entities. The simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
