Abstract

The invention provides a fire-fighting device, a box body assembly, a battery, an electric device and a method for preparing the battery, and relates to the technical field of battery safety. The fireprotection device comprises a pipeline, a gas release mechanism and a blocking structure, wherein the pipeline is provided with a gas inlet end and a gas exhaust end, and the gas inlet end is used for being connected with a box body of the battery, so the combustible gas generated during thermal runaway of the battery can enter the pipeline from the box body through the gas inlet end and is exhausted out of the pipeline through the gas exhaust end; the gas release mechanism is used for being connected with a pipeline, and the gas release mechanism is configured to release fire-fighting gas into the pipeline when the battery is in thermal runaway; the pipeline is internally provided with a blocking structure, and the blocking structure is used for blocking combustible gas and fire-fightinggas and changing the flowing direction, so the combustible gas and the fire-fighting gas can be mixed before being discharged out of the pipeline. The fire protection device provided by the inventioncan reduce the risk of generating open fire during thermal runaway of the battery, and can inhibit spreading of the thermal runaway of the battery.

Description

technical field [0001] The present application relates to the technical field of battery safety, in particular, to a fire-fighting device, a box assembly, a battery, an electrical device and a method for preparing the battery. Background technique [0002] Batteries are energy storage devices that are at the heart of hybrid and electric vehicles. When the battery is overcharged or overdischarged or short-circuited, thermal runaway will occur, and flammable gas may be emitted, which may explode and cause a fire. Therefore, it is necessary to carry out fireproof treatment on the battery. Contents of the invention [0003] The present application aims to provide a fire-fighting device, a box assembly, a battery, an electrical device and a method for preparing the battery, so as to reduce the risk of an open flame when the battery is thermally out of control. [0004] In the first aspect, the embodiment of the present application provides a fire-fighting device for a battery...
