The present invention discloses an exhaust filter system for a battery pack, including an explosion-proof valve and a filter apparatus. One end of the explosion-proof valve is connected to a battery pack. The other end of the explosion-proof valve is connected to the filter apparatus. The filter apparatus includes an introduction port, a discharge port, a housing, and a filter mechanism. The introduction port and the discharge port are separately disposed at two ends of the housing. The filter mechanism is disposed inside the housing. The filter mechanism is provided with a plurality of filter holes. The present invention has the following beneficial effects: by optimal design of a novel explosion-proof valve and a novel filter apparatus, the applicability of technical solutions of this application is made more extensive. The problem of fire induced by thermal runaway can be satisfactorily solved for both high-capacity batteries and small-capacity batteries. Combustion gas is exhausted more smoothly, and a better filtering effect and a better effect on post handling for thermal runaway in a battery pack are obtained.

A system for mitigating fire within a battery storage container enclosing an energy storage system includes a sensor configured to detect a precursor condition indicative of a potential fire or explosion, a controller, and a set of extendable battery trays, each including a tray ejector and containing a set of battery cells. The controller detects a precursor condition in a battery tray via the sensor and ejects the battery tray to increase the distance between the battery tray and adjacent battery trays. The system can include a cooling channel in the battery tray configured to cool the set of battery cells, and/or a nozzle configured to direct fluid into the battery tray to suppress the precursor condition. In one variation, the system includes a door of the container configured to open, venting the interior of the container in response to detection of a precursor condition indicating a potential explosion.
