Abstract
A method for predicting the explosion pressure of a medium- and large-size cell module, according to the present invention, comprises the steps of: (S) deriving a profile (SOC-temperature profile) of the generation temperature according to a state of charge (SOC) of a medium- and large-size cell module to be predicted; (S) mounting a small cell inside an explosion pressure measurement device; (S) overcharging the small cell until an explosion occurs while heating the small cell in the same manner as the SOC-temperature profile derived in step (S); (S) measuring the pressure during the explosion of the small cell; and (S) converting the pressure during the explosion of the measured small cell into pressure of a medium- and large-size cell module.
