The Battery Equivalent Circuit block models the battery terminal voltage by using a combination of electrical circuit elements arranged in a specific circuit topology.

First-order equivalent circuit model for Li-ion cell. 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.

ECMs use electrical components like resistors, capacitors, and voltage sources to simulate the electrical response of the battery, as opposed to electrochemical models, which are based on …

Batteries do supply a voltage to a load. And, when the cell is unloaded and in complete equilibrium (i.e., “open circuit”), the voltage is fairly predictable. An ideal voltage source will be …
