摘要： A system for detecting gas leakage within a battery pack includes a battery pack, a controller, and a detector. The battery pack comprises a plurality of cells which may be subject to a gas leakage. The detector is remotely mounted from the battery pack and is connected to the battery pack via airtight tubing. A fan conducts air from the battery pack to the detector. The detector is configured to read a concentration value of one or more gases. The detector is electrically connected to the controller and is configured to a return signal indicative of no alarm, a first alarm level, or a second alarm level to the controller. The controller is configured to output no alarm, a first alarm level or a second alarm level in response to the return signal. Emergency response procedures are implemented based on the level of gas leakage within the battery pack.

摘要： A fire suppressant (932) for cooling a battery cell in a battery pack includes a pressurized mixture of an organic compound (934) and carbon dioxide (936). The organic compound is 1,1,1,2,2,4,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone. A ratio of a mass of the organic compound to a mass of the carbon dioxide is between 1:4 and 4:1. The mixture is pressurized above a vapor pressure of the carbon dioxide. The carbon dioxide, when depressurized, evaporates and cools the organic compound and the battery cell. The mixture, when depressurized, flows through the battery cell. An amount of the fire suppressant flowed through the battery pack is equal to or greater than an inerting volume of fire suppressant for the battery pack.

摘要： A system for detecting gas leakage and/or a fire event within a battery pack includes a battery pack (24), a controller (144), a gas detector (124), and an infrared detector (140). The battery pack comprises a plurality of cells which may be subject to a gas leakage or a fire. The gas detector is configured to read a concentration value of one or more gases. The infrared detector is configured to read a level of infrared radiation. The gas detector and the infrared detector are configured to transmit alarm level signals to a controller. The controller is configured to output a first or second alarm level in response to the concentration value of gas. The controller is configured to output a third alarm level in response to the level of infrared radiation. Emergency response procedures may be implemented based on the level of gas leakage or infrared radiation within the battery pack indicated.

摘要： A system for detecting gas leakage within a battery pack includes a battery pack, a controller (144), and a detector (124). The battery pack comprises a plurality of cells which may be subject to a gas leakage. The detector is configured to sense a concentration value of one or more gases. The detector is further configured to generate a return signal indicative of no alarm, a first alarm level, or a second alarm level. The detector is electrically connected to the controller and is configured to transmit the return signal to the controller. The controller is configured to output a first alarm level or a second alarm level in response to the return signal.

摘要： A valve assembly (10) for a pressure vessel (16) is disclosed that includes a valve housing (12) operatively associated with an outlet (14) of the pressure vessel, a frangible hermetic disc (18) sealing the outlet of the pressure vessel, and a poppet valve (20) mounted for movement within the valve housing between a first position supporting the frangible hermetic disc within the outlet of the pressure vessel and a second position spaced apart from the frangible hermetic disc to permit the frangible disc to burst under pressure and permit the egress of pressurized material from the pressure vessel through the outlet.

摘要： A fire suppression system (100) includes a detector (124), a controller (144), and an emergency entry point (156). The battery pack (112) includes an inlet, a plurality of battery modules (122) housing battery cells, and an outlet. The detector senses a condition indicative of a fire event caused by a battery cell breaking down and produces a signal representing the condition. The controller is electronically connected to the detector. The controller determines a fire event is occurring in the battery pack based on the signal representing the sensed condition. The emergency entry point is fluidly connected to the battery pack inlet. The emergency entry point is connectable to an emergency fire suppressant source. The emergency fire suppressant flows through the emergency entry point and through the battery pack when the emergency fire suppressant source is connected to the emergency entry point.

摘要： A fire suppression system for a battery pack includes a controller, an inlet line, an outlet line, a detector, a first pressure vessel with a first valve, and a second pressure vessel with a second valve. The pack includes: an inlet, battery modules housing battery cells, and an outlet. The inlet line connects to the pack inlet and the outlet line connects to the outlet. The detector senses a condition indicative of a fire event caused by a battery cell breaking and produces a signal. The controller, connected to the detector, determines a fire event is occurring based on the signal. The first vessel and the second vessel connect to the inlet line. A first suppressant flows from the first vessel into the pack when the controller opens the first valve. A second suppressant flows from the second vessel into the pack when the controller opens the second valve.
