Abstract
A battery module includes a housing which accommodates a plurality of battery cells therein, and has a vent-hole portion formed therein; a top cover which is movably installed on the housing so as to open/close the vent-hole portion; an elastic member which is installed to apply an elastic force to the top cover in a direction in which the top cover opens the vent-hole portion; and a stopper configured to support the top cover so that the top cover maintains a closed state of the vent-hole portion. The stopper can lose or reduce support to the top cover due to changes in temperature or pressure.
Claims20
A battery module comprising:
- a housing accommodating a plurality of battery cells therein and provided with a vent hole portion;
- a top cover movably installed on the housing to open and close the vent hole portion;
- an elastic member installed to apply an elastic force to the top cover in a direction to have the vent hole portion opened by the top cover;
- and
- a stopper supporting the top cover to maintain the vent hole portion closed,
- wherein the stopper is configured to support the top cover, and lose or reduce support to the top cover at a temperature equal to or higher than a predetermined temperature or at a pressure equal to or higher than a predetermined pressure.
A battery module comprising:
- a housing accommodating a plurality of battery cells therein and provided with a vent hole portion;
- a top cover movably installed in the housing;
- an elastic member applying an elastic force to the top cover;
- and
- a stopper resisting the elastic force to resist the top cover from moving by the elastic force,
- wherein the stopper has a resistance to the elastic force, and
- wherein the resistance decreases at a temperature equal to or higher than a predetermined temperature or at a pressure equal to or higher than predetermined pressure.
