Abstract
A vent includes a gas inlet configured to allow gas to be introduced therethrough, a gas outlet configured to allow the gas introduced through the gas inlet to be discharged to the outside therethrough, an alarm means provided at one side of the gas outlet, the alarm means being configured to generate sound when the gas is discharged to the outside, a connection portion configured to connect the gas inlet and the gas outlet to each other, and a sealing cap located in the connection portion, the sealing cap being configured to automatically discharge gas to the outside, whereby gas generated in a battery cell or a battery module is automatically discharged to the outside.
Claims14
A venting device configured to discharge gas in a battery cell or a battery module to an outside, comprising:
- a gas inlet configured to allow gas in the battery cell or the battery module to be introduced therethrough;
- a gas outlet configured to allow the gas introduced through the gas inlet to be discharged to the outside therethrough;
- an alarm provided at one side of the gas outlet, the alarm being configured to generate a sound when the gas is discharged to the outside;
- a connection portion configured to connect the gas inlet and the gas outlet to each other;
- and
- a sealing cap located in the connection portion, the sealing cap being configured to move to discharge gas to the outside,
- wherein the sealing cap blocks connection between the gas inlet and the gas outlet, thereby blocking discharge of gas and introduction of external air, in a normal state, and moves in the connection portion under a predetermined condition such that the gas inlet and the gas outlet are connected to each other, and
- wherein the connection portion is made of a heat shrink tube configured to shrink at a temperature of the gas in the battery cell to move the sealing cap such that the gas inlet and the gas outlet are connected to each other.
A venting device configured to discharge gas in a battery cell or a battery module to an outside, comprising:
- a gas inlet configured to allow gas in the battery cell or the battery module to be introduced therethrough;
- a gas outlet configured to allow the gas introduced through the gas inlet to be discharged to the outside therethrough;
- an alarm provided at one side of the gas outlet, the alarm being configured to generate a sound when the gas is discharged to the outside;
- a connection portion configured to connect the gas inlet and the gas outlet to each other;
- and
- a sealing cap located in the connection portion, the sealing cap being configured to move to discharge gas to the outside,
- wherein the sealing cap blocks connection between the gas inlet and the gas outlet, thereby blocking discharge of gas and introduction of external air, in a normal state, and moves in the connection portion under a predetermined condition such that the gas inlet and the gas outlet are connected to each other,
- wherein the connection portion is made of a heat shrink tube configured to shrink at a predetermined temperature or higher, and
- wherein a lower part of the heat shrink tube thermally shrinks at a lower temperature than an upper part of the heat shrink tube.
