AIR VALVE FOR ENERGY STORAGE DEVICE AND ENERGY STORAGE DEVICE INCLUDING THE SAME

摘要

Disclosed herein is an air valve for an energy storage device, including: a valve body mounted in a gas vent of an energy storage device and having a passage for discharging gases within the gas vent to the outside; and a plurality of magnets mounted within the passage to apply repulsion force to one another so as to block the gas vent from the outside by the repulsion force and communicate the gas vent with the outside when a gas pressure within the gas vent is larger than the repulsion force, thereby discharging gases. By this configuration, exemplary embodiments of the present invention can configure the air valve with the simple structure capable of smoothly discharging gases generated from the energy storage device while minimizing a volume of the air valve and being semi-permanently used while minimizing a mechanical configuration of the air valve.
