Energy storage battery container, battery energy storage fire extinguishing system and application method thereof

Abstract

The invention discloses an energy storage battery container, a battery energy storage fire extinguishing system and an application method thereof. According to the energy storage battery container, physical isolation of any energy storage battery can be supported; the energy storage battery container comprises a container and a battery frame installed in the container, wherein a channel separationgate is arranged on an outer wall of the container for each battery installation position, a battery box installation position is arranged on the battery frame, and a battery box separation module used for withdrawing a battery box from the container through the channel separation gate is arranged on the battery installation position. The energy storage battery container is advantaged in that anoperation electrical state and an environment state of the energy storage battery box can be monitored in real time to realize identification of thermal runaway of the battery box, separation of the thermal runaway battery box can be controlled to achieve physical isolation between a thermal runaway battery box and a normally-running battery box, the isolated thermal runaway battery box can be further monitored in real time, and extinguishment serves as a final fire safety defense line.

AI Technical Summary

Problems solved by technology

This solution physically isolates the area where the thermal runaway battery box is located from other areas, which can reduce the risk of spread caused by the fire of the battery box, but other normal operating battery boxes in the isolated area may still be affected, causing unnecessary losses
