Abstract: A fire suppression system for a vehicle includes a housing, multiple battery cells positioned within the housing, an off-gas detector, and a controller. The off-gas detector is provided within the housing and is configured to detect a presence of off-gas in the housing. The controller is configured to receive signals from the off-gas detector indicating whether off-gas is detected in the housing, and activate a fire suppression apparatus to provide fire suppressant agent to any of an exterior or interior of the housing in response to detecting off-gas in the housing.

Abstract: A modular fire suppression unit includes a housing, an off-gas detector, a fire suppression apparatus, and a controller. The off-gas detector is provided within the housing and is configured to obtain air samples and detect a presence of off-gas in each air sample. The fire suppression apparatus is provided within the housing and configured to provide a fire suppression agent to a space. The controller is provided within the housing and is configured to receive signals from the off-gas detector indicating whether off-gas is detected in each of the air samples. The controller is also configured to activate the fire suppression apparatus to provide the fire suppression agent to the space in response to detecting off-gas in one or more of the air samples. The modular fire suppression unit is configured to be coupled to a sidewall of an enclosure.
