Description

Fireproof battery cabinet Technical Field The utility model relates to the technical field of lithium batteries, in particular to a fireproof lithium battery cabinet. Background Because of the popularization of electric vehicles, a battery charging cabinet or a battery replacement cabinet is adopted to charge the battery or replace the charged battery in order to adapt to and meet the requirements of quick battery charging or power consumption. Batteries, particularly lithium batteries, are prone to fire during charging or storage due to short circuits and the like. The prior battery charging cabinet or battery replacing cabinet is internally provided with a dry powder fire extinguisher, a spray pipe and the like to extinguish the fire of the battery. However, because a great amount of heat and fire light are instantaneously generated when the lithium battery is in thermal failure, the dry powder amount of the dry powder fire extinguisher and the water amount of the spray pipe in a short time are insufficient to extinguish the fire, the batteries of other battery bins in the battery cabinet are easily influenced, even the batteries of the whole cabinet are ignited, and the loss is large.
