Problems solved by technology

[0003] The power supply of pure electric vehicles comes from the battery pack. Although clean energy is used, battery fire incidents of electric vehicles are common, mainly because the working environment of the battery is relatively complicated. At present, the problem of battery fire has not been solved, and the existing Electric vehicle battery packs are not equipped with corresponding devices that can prevent the rapid spread of fire. Most measures are taken to prevent fire with flame-retardant materials, but the effect is minimal

Embodiment 1

[0040] see Figure 1-6 , an electric vehicle with a fire prevention device, including a package shell 1 and multiple battery packs 4, please refer to Figure 4-6 , the inner wall of the package shell 1 is bonded with a glass wool board 10, the glass wool board 10 has the effect of fire prevention, can prevent the torch from burning through the package shell 1, and prevent the fire from spreading outward. A side plate 2, a plurality of partitions 3 are fixedly connected in the package shell 1, and the partitions 3 are located between the side plates 2, both the side plates 2 and the partitions 3 are made of ceramic materials, and the side plates 2 and the partitions 3 The thickness is 2-4 mm. On the one hand, the ceramic material is fireproof to prevent itself from being burned by fire. On the other hand, the brittleness of ceramics is used to allow the adsorption balls 9 in the side plate 2 and partition 3 to come out, so the thickness of the ceramics should not be too thin A...

Abstract

The invention discloses an electric vehicle with a fireproof device, and belongs to the technical field of electric vehicle batteries. The electric vehicle with the fireproof device comprises a packaging housing and a plurality of battery packs; the inner side wall of the packaging housing is fixedly connected with a plurality of side plates; a plurality of partition plates are fixedly connected in the packaging housing, and the partition plates are positioned between the side plates, so that open fire of the battery can be delayed, and harmful liquid in the battery can be prevented from volatilizing into the air; by limiting lateral expansion of the battery, and by using iron wires on an iron wire net and iron plates to stop the battery from expanding, open fire occurrence time is delayed, and precious time is bought for rescue or escape; meanwhile, harmful liquid flowing out of the broken battery is absorbed by adsorption balls, so that liquid is prevented from diffusing to the outside; and the adsorption balls expand after absorbing the liquid so as to burst the side plates and the partition plates which are made of ceramic materials, and therefore, the adsorption balls can forma layer of film on comburent under the action of open fire so as to isolate air, and the fire extinguishing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle batteries, and more specifically relates to an electric vehicle with a fire prevention device. Background technique [0002] At present, in the technical route of various new energy vehicles, electric vehicles represented by hybrid, pure electric vehicles and fuel cell vehicles are generally considered to be the main direction for the transformation and development of future automotive energy and power systems, and have become the world's automobile power and Development priorities of major automakers. [0003] The power supply of pure electric vehicles comes from the battery pack. Although clean energy is used, battery fire incidents of electric vehicles are common, mainly because the working environment of the battery is relatively complicated. At present, the problem of battery fire has not been solved, and the existing Electric vehicle battery packs are not equipped with correspondin...
