As the short-circuit current is relatively small and not easily observable, the short-circuit resistance is used to quantify the estimation results of the short-circuit. Additionally, since the polarization induced by the MSC at both ends of the cell is limited, the cell terminal voltage can be approximated to the voltage across the short-circuit.
