摘要： Disclosed in the present application are an automatic drain valve, a battery and a power consuming device. The automatic drain valve comprises a valve body and a water-soluble assembly, wherein the valve body is provided with a sealed chamber, and a first opening and a second opening which communicate with the sealed chamber; the valve body penetrates and seals a drain port; the first opening is located on the inner side of the drain port; the second opening is exposed from the drain port; the water-soluble assembly is arranged in the sealed chamber and seals the second opening; and after a water-soluble member in the water-soluble assembly is dissolved in water, the water-soluble assembly opens the second opening. The valve body penetrates and seals the drain port, the first opening, the sealed chamber and the second opening of the valve body cooperate to form a channel for communicating the inside of a case with the outside thereof, and the water-soluble assembly is arranged in the channel and blocks the channel, such that after water/a cooling liquid enters the channel through the first opening and contacts the water-soluble member of the water-soluble assembly, the water-soluble member is dissolved, and the channel is unblocked, thereby enabling the water/the cooling liquid to be discharged through the second opening. Therefore, the use danger of a battery can be reduced.

摘要： An energy storage system (200, 300, 400, 500) for an aircraft (10) includes an enclosure (202, 302, 402, 502) comprising at least one vent hole (204, 304, 404, 504); a plurality of energy storage devices (206, 206, 406, 506) arranged in the enclosure (202, 302, 402, 502); a ventilation system comprising: an electrical circuit (210, 310, 410, 510) comprising at least one conductor (212, 312, 412, 512) arranged across the plurality of energy storage devices (206, 206, 406, 506); a power source (214, 314, 414, 514) electrically coupled to and powering the electrical circuit (210, 310, 410, 510); and a thermal vent mechanism (216, 316, 416, 516) positioned adjacent to the at least one vent hole (204, 304, 404, 504). During normal operation, the electrical circuit (210, 310, 410, 510) is open and the thermal vent mechanism (216, 316, 416, 516) covers the at least one vent hole (204, 304, 404, 504). During a thermal event, the thermal event causes the electrical circuit (210, 310, 410, 510) to close such that the power source (214, 314, 414, 514) activates the thermal vent mechanism (216, 316, 416, 516) to expose the at least one vent hole (204, 304, 404, 504) to vent fumes outside of the aircraft (10).
