Problems solved by technology

First, if a thermal runaway reaction occurs during charging and discharging, it may cause the battery to short-circuit and catch fire, or even explode.
Second, if extreme conditions such as collision, extrusion, or drop occur, the internal short circuit of the battery will be caused, which will also cause a dangerous situation.
2. The use of gas (air) as the heat transfer medium has

Abstract

The invention discloses a device for preventing burning and explosion of new energy automobile batteries caused by thermal runaway, and relates to a battery device technology. The device comprises a temperature control unit and a battery box body. An output conduit is mounted at the upper end of one side of the battery box body, and an input conduit is mounted at the lower end. The output conduitof the battery box body is communicated with a radiator through a pipeline, the radiator is communicated with a water pump through a pipeline, the water pump is communicated with a water tank througha pipeline, and the water tank is communicated with the input conduit of the battery box body through a pipeline. The temperature control unit is electrically connected with the battery box body, thewater pump and a radiator fan respectively. The battery box body is filled with circulating liquid. The device for preventing burning and explosion of new energy automobile batteries caused by thermalrunaway provided by the invention enables automobile batteries to have the functions of temperature control, insulation, flame retardancy and prevention of burning and explosion caused by thermal runaway.

Description

technical field [0001] The invention relates to the technical field of battery devices, in particular to a device for preventing thermal runaway explosion of batteries of new energy vehicles. Background technique [0002] Pure electric vehicles are currently the only choice for new energy vehicles, and they are also an important measure at home and abroad to solve vehicle pollution, promote low-carbon travel, and promote green environmental protection. The so-called pure electric vehicles use batteries as power sources and are driven by electric motors. The battery is its heart and key, as well as its life and value. For many people, new energy vehicles are a recently emerging type of vehicle. Due to the impact of the environment, our current traditional fuel vehicles are greatly restricted, so the promotion of new energy vehicles is becoming more and more widespread. The manufacturing time of new energy vehicles is very short, so there will definitely be deficiencies in t...
