Abstract
A fire suppression system for use with lithium-ion battery storage containers is provided. The system utilizes water as a fire suppressant, which is stored in a tank and delivered to a battery module within the container that is experiencing a thermal event. After a predetermined time from the beginning of water flow, a controller within the system actuates one or more fans to ventilate the storage container to expel hazardous gases produced by the thermal event.
Claims14
A method of suppressing a fire within one or more battery containers comprising:
- providing a water storage tank and a propellant tank connected to the water storage tank, the propellant tank being configured to introduce a pressurized gas into the water storage tank;
- providing a conduit network that is connected with the water storage tank and that extends into the one or more battery containers, the one or more battery containers comprising a plurality of battery racks each of which is configured to hold a plurality of battery modules, the conduit network comprising a plurality of nozzles each operable to deliver water from the water storage tank to one or more battery modules;
- delivering a flow of the water from the water storage tank through at least one of the plurality of nozzles in response to detection of a thermal event occurring within at least one of the battery modules;
- detecting an operational condition associated with the water storage tank;
- and
- activating one or more exhaust fans located within the one or more battery containers in response to the detection of the operational condition associated with the water storage tank.
