There are provided a thermally expandable fire-resistant material for battery pack and a fire-resistant sheet for battery pack, which have high flame retardancy and thermal insulation properties to thermal runaway and ignition of on-vehicle batteries. The thermally expandable fire-resistant material for battery pack is one to be used for a battery pack to be mounted on vehicles, and contains a resin and a thermally expandable compound, and has an expansion ratio in a case where heated at 600° C. of 2.5 times or more.

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.

An aircraft including a battery pack having a plurality of battery cells arranged to vent into a venting region of the battery pack. A path is defined between the venting region and an exterior of the aircraft, whereby thermal products vented by the cells can exit the aircraft via the path. In some embodiments, the venting region is or is in fluid communication with an air channel through which air flows from an aircraft air inlet to an aircraft air outlet. In other embodiments, the path joins the venting region and an opening in an external surface of the aircraft.

Discussed is a battery pack including a plurality of battery modules; a venting inducing frame disposed along edges of the plurality of battery modules and forming a venting passage to vent at least one of gas and flame; a venting gate to connect an inside of at least one of the plurality of battery modules and the venting inducing frame; and a quenching member disposed in a passage of the venting gate.
