Abstract
A method of setting a cell pressure range includes based on performance data of a secondary battery cell, determining, as Pcell_min, a minimum pressure for realizing performance of the secondary battery cell, and determining, as Pcell_max, a maximum pressure for realizing performance of the secondary battery cell; and a second operation of determining, as Pmodule_min, a minimum pressure at which a cell stack may be supported and fixed, and determining, as Pmodule_max, a maximum pressure at which the cell stack may be pressed without damage to a module housing in end of life (EOL) of secondary battery cells, wherein an intersection range of the Pcell_min to the Pcell_max and the Pmodule_min to the Pmodule_max is set as the cell pressure range.
