A new energy battery protection device with early warning and fire prevention functions

Abstract

The invention discloses a new energy battery protection device with an early warning and fire protection function, which relates to the technical field of battery protection, and includes a storage box and a sealing cover. The outer wall of the storage box is fixedly provided with two semi-circular ventilation pipes 1, and One of the two semi-annular ventilation pipes is annularly arranged. The new energy battery protection device with early warning and fire prevention function can pass through the semi-annular air pipe 1, semi-annular air pipe 2 and semi-annular air pipe 3 provided on the outer wall of the storage box and the sealing cover when the blower blows air. The circular pipe one transports the wind to the semi-annular air pipe one, and by connecting the semi-annular air pipe two with the semi-annular air pipe one, and the semi-annular air pipe three with the semi-annular air pipe two, the wind can be passed through multiple The ventilation holes are conveyed into the storage box, which can directly blow the wind to each surface of the battery, and then realize the rapid cooling of the battery.

Description

technical field [0001] The invention relates to the technical field of battery protection, in particular to a new energy battery protection device with early warning and fire prevention functions. Background technique [0002] Electric vehicles have become the key development direction of major automobile companies. In order to ensure the high performance of on-board batteries under different external operating temperatures, more and more researches have been done on battery protection devices. The on-board batteries in the battery box may catch fire due to emergencies , It is easy to cause accidents, etc. Therefore, the design of a new energy vehicle battery box fire extinguishing device is of great significance for eliminating vehicle fires, reducing personal casualties and property losses. [0003] In the prior art, the battery storage device cools the battery by using a blower to blow wind into the battery storage device to cool the battery. Although this method can achi...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a new energy battery protection device with the function of early warning and fire prevention, which solves the problem that the prior art uses a blower to blow the wind into the battery storage device to cool the battery. Although the cooling can be achieved, the The wind cannot be directly transported to the surface of the battery, which will lead to a slow cooling of the battery and an unsatisfactory cooling effect. The existing battery storage device cannot quickly transport the fire extinguishing material to the surface of the battery when extinguishing the fire, which will lead to poor fire extinguishing. timely question
