EXPLOSIVE PRESSURE MEASUREMENT SYSTEM FOR MIDDLE OR LARGE SIZED CELL AND METHOD FOR MEASURING EXPLOSIVE PRESSURE OF MIDDLE OR LARGE SIZED CELL MODULE USING THE SAME
EXPLOSIVE PRESSURE MEASUREMENT SYSTEM FOR MIDDLE OR LARGE SIZED CELL AND METHOD FOR MEASURING EXPLOSIVE PRESSURE OF MIDDLE OR LARGE SIZED CELL MODULE USING THE SAME
According to the present invention, an explosion pressure prediction method of medium-to-large cell modules comprises: a step (S100) of deriving a profile (SOC-temperature profile) of a temperature generated according to a charged amount (SOC) of the medium-to-large cell module to be predicted (S100); a step (S200) of mounting a small cell inside an explosion pressure measuring device; a step (S300) heating the small cell in the same manner as the SOC-temperature profile derived in step (S100) and overcharging the same until an explosion takes place; a step (S400) of measuring the pressure when the small cell is exploded; and a step (S500) of converting the measured pressure of the small cell to the pressure of the medium-to-large cell module.
