Abstract

The invention provides a battery box with a fire-fighting structure and an energy-storage battery cabinet. The battery box comprises a box body provided with an air inlet structure communicating withthe interior of the box body, an air outlet mechanism arranged on the box body and communicating with the interior of the box body, a fire-fighting pipeline communicating with the interior of the boxbody and close to the air outlet mechanism, wherein the air inlet structure and the air outlet mechanism are arranged on the two sides of the box body respectively. According to the battery box, the air inlet structure and the air outlet mechanism are arranged on the box body, so that on one hand, air in the box body can flow to cool the interior of the box body and ensure the temperature during operation of a battery, and on the other hand, a gaseous extinguishing agent can be introduced during battery burning to effectively extinguish open fire; a liquid extinguishing agent is introduced into the box body through the fire-fighting pipeline after the open fire is extinguished; the liquid extinguishing agent can be stored in an inner space of the box body; and the battery re-burning can beprevented under the soaking of the liquid extinguishing agent.

Description

technical field [0001] The invention relates to the technical field of battery boxes, in particular to a battery box and an energy storage battery cabinet with a fire-fighting structure. Background technique [0002] Lithium-ion batteries have the advantages of large specific capacity, high working voltage, long cycle life, small size, and light weight, and can be used in many scenarios. In electric vehicles and battery modules, the power battery of the power supply is required to have a large capacity and voltage, so it is necessary to install multiple single cells in the battery box, and multiple single cells are connected in series and parallel to form a battery pack, so as to achieve To meet the requirements of the power source, multiple battery boxes are combined to form an energy storage power station. When a fire occurs, the gas fire extinguishing agent can effectively extinguish the open flame, but lithium batteries have a greater possibility of re-ignition due to t...
