Lithium battery energy storage container with fire isolation function and fire isolation method thereof

Abstract

The invention discloses a lithium battery energy storage container with the fire isolation function and a fire isolation method thereof. The lithium battery energy storage container is internally provided with an energy storage unit, wherein the energy storage unit includes multiple closable battery cabinets, an air conditioning refrigeration system and a fire control system, the fire control system includes an explosion-proof valve disposed at the top of a battery cabinet, a fire fighting liquid spraying device for fire fighting liquid discharge, a fire extinguishing agent spraying device, asmoke detector, and a fire fighting liquid discharge pipe disposed at the bottom of the battery cabinet, release and discharge of fire fighting fluid are realized by a fire fighting system through controlling the corresponding solenoid valves according to signals of the smoke detector, and the air conditioning system is used for controlling the temperature of the battery cabinets. The lithium battery energy storage container is advantaged in that separate monitoring and fire treatment for each battery cabinet are performed, monitoring accuracy is improved, moreover, by performing fire treatment and physical isolation of the single battery cabinets in which a fire occurs, thermal runaway of batteries can be effectively suppressed.

Description

technical field [0001] The invention relates to energy storage technology, in particular to a lithium battery energy storage container with a fireproof isolation function and a fireproof isolation method thereof. Background technique [0002] As a new energy battery, lithium-ion batteries are not only more environmentally friendly but also have superior performance, and are widely used in energy storage power stations. However, during the storage process, lithium-ion batteries may experience thermal runaway due to the accumulation of heat generated by their own chemical reactions or the influence of external heat sources, which seriously affects the safety performance of energy storage power stations. [0003] The current technology mainly realizes the early warning and fire protection of the energy storage power station through the following methods: a plurality of different types of fire detectors (temperature-sensing, smoke-sensing or smoke-temperature-integrated) are ins...

AI Technical Summary

Problems solved by technology

This method of monitoring and fire fighting is not practical, because once a fire occurs in a single battery box in the battery cabinet, other battery boxes in the battery cabinet will be affected by collateral, posing a safety hazard and cannot be used any longer
