Abstract
A venting pressure measuring apparatus measures pressure at which a venting cover of a battery module ruptures, and includes: a pressure jig that allows the venting cover to be placed and supported thereon, and is provided with a pressure space formed to apply pressure to the venting cover; and a top jig that presses the venting cover into close contact with the pressure jig, and is provided with a through hole formed at a position corresponding to the pressure space. A gas flow when venting occurs in the battery module is simulated by shapes of the pressure space and the through hole.
Claims18
A venting pressure measuring apparatus comprising:
- a pressure jig configured to allow a venting cover of a battery module to be placed and supported thereon, and provided with a pressure space formed to apply pressure to the venting cover;
- and
- a top jig configured to press the venting cover into close contact with the pressure jig, and provided with a through hole formed at a position corresponding to the pressure space,
- wherein a gas flow when venting occurs in the battery module is simulated by shapes of the pressure space and the through hole thereby allowing a pressure at which the venting cover ruptures to be measured.
A venting pressure measuring method for measuring a venting pressure of a venting cover used as a component of a battery module, the venting pressure measuring method comprising:
- a placing step of placing the venting cover in a pressure jig provided with a pressure space;
- a fixing step of pressing the venting cover using a top jig provided with a through hole formed at a position corresponding to the pressure space, thereby bringing the venting cover into close contact with the pressure jig;
- and
- a pressure applying step of applying pressure to the venting cover through the pressure space.
