Abstract
A fire suppression system includes a battery enclosure, a liquid carbon dioxide (CO2) storage system, and a controller. The liquid CO2 storage system is fluidly coupled to the battery enclosure. The controller is configured to receive an indication of a fire condition associated with the battery enclosure. The controller is configured to control operation of the liquid CO2 storage system to provide liquid CO2 to an interior of the battery enclosure. The liquid CO2 converts into dry ice to cool the battery enclosure.
Claims20
A fire suppression system comprising:
- a sensor configured to monitor a battery compartment;
- a liquid carbon dioxide (CO2) supply configured to selectably discharge liquid CO2;
- a manifold fluidly coupled with the liquid CO2 supply and configured to selectably direct the liquid CO2 to the battery compartment via a conduit;
- a controller configured to:
- receive sensor signals from the sensor;
- detect a fire event at the battery compartment based on the sensor signals;
- and
- operate the liquid CO2 storage system and the manifold to discharge liquid CO2 into the battery compartment based on detecting the fire event.
A fire suppression system comprising:
- a battery enclosure configured to hold a Lithium Ion battery;
- a liquid carbon dioxide (CO2) storage system coupled to the battery enclosure;
- a controller configured to:
- receive an indication of a fire condition associated with the battery enclosure;
- and
- control operation of the liquid CO2 storage system to provide liquid CO2 to an interior of the battery enclosure;
- wherein the liquid CO2 converts into dry ice within the interior to cool the Lithium Ion battery within the battery enclosure.
A method comprising:
- receiving, by a controller, sensor data associated with a battery enclosure;
- determining, by the controller, that a fire condition exists within the battery enclosure based on the sensor data;
- controlling, by the controller, a CO2 storage and delivery system to provide liquid CO2 from a CO2 storage system to the battery enclosure based on determining that the fire condition exists within the battery enclosure.
