A kind of electric vehicle with fire prevention device

Abstract

The invention discloses an electric vehicle with a fire prevention device, which belongs to the technical field of electric vehicle batteries. An electric vehicle with a fire prevention device comprises a packaging case and a plurality of battery packs. The inner side wall of the packaging case is fixedly connected with a plurality of sides. There are multiple separators fixedly connected to the packaging shell, and the separators are located between the side plates, which can delay the battery from igniting, and can also prevent the harmful liquid in the battery from volatilizing into the air. By limiting the lateral expansion of the battery, In this way, the iron wire and iron sheet on the barbed wire net can be used to prevent the expansion of the battery, delay the appearance of open flames, and buy precious time for rescue or escape. In the outside world, and the adsorption ball will expand after absorbing the liquid, so as to break the side plates and partitions made of ceramic materials, so that the adsorption ball can form a film on the burning material under the action of the open flame to isolate the air, thereby To achieve the role of fire extinguishing.

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...

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
