In addition, it should be noted that the case and the battery module are familiar to those skilled in the art and are not in the scope discussed in the present invention, and the description is not repeated for illustration.
Those skilled in the art will appreciate that there are many alternative fire extinguishing materials under the above-described configuration. In particular, the fire extinguishing material is required to have flame retardant, heat insulation and fire extinguishing effects after being released. Such as either a fire suppressant, or a coolant, or a phase change material. Specifically, such fire extinguishing materials include, but are not limited to, aerosol fire extinguishing agents, hexafluoropropane, heptafluoropropane, perfluorohexane, perfluorohexanone, perfluoropolyether, carbon dioxide, ammonium perfluorooctanoate, ethoxypentafluorocyclotriphosphazene, hexafluoropropylene trimer, trifluoroethyl phosphate, perfluorononene, hydrofluorocarbon compounds, cac 2.6h2O, Na2SO 4.10h2O, CaBr 2.6h2O, CH3 coona.3h2O, paraffins and mixtures of one or more of various acid esters, aliphatic hydrocarbons, aliphatic acids, alcohols, and polyenols. Among them, the hydrofluorocarbon compounds include, but are not limited to, R134A, R125, R32, R407C, R410A, R152, and the like. The aerosol fire extinguishing agent can be KNO3, Sr (NO3)2, strontium compound and the like; those skilled in the art will appreciate that fire extinguishing materials also generally need to be materials that are non-toxic and non-polluting to the environment.
In order to facilitate the rapid triggering of the fire extinguishing apparatus 13, a heat conducting silica gel, a heat conducting silicone grease, a heat conducting rubber mat, or other materials with high heat conductivity are disposed on the top of the fire extinguishing apparatus 13. So that the bottom of the battery in the battery module is in heat-transferring contact with the fire extinguishing device 13, that is, the heat/high temperature generated by thermal runaway of a certain battery is quickly transferred to the fire extinguishing device 13, thereby quickly triggering the fire extinguishing device 13.
In addition, a temperature sensing line (not shown) may be further provided on the fire extinguishing device 13. The temperature sensing line is an ignition line, one end of the temperature sensing line is arranged on the fire extinguishing device 13 and is connected with a medicament bag arranged in the fire extinguishing device 13, and the other end of the temperature sensing line is opposite to the battery safety valve. Therefore, the battery thermal runaway is realized, the temperature sensing line is ignited through the high-temperature substance sprayed out of the battery safety valve, and the medicament bag arranged in the fire extinguishing device 13 is ignited through the temperature sensing line, so that the shell 131 of the fire extinguishing device 13 is exploded, and the fire extinguishing material arranged in the fire extinguishing device 13 is released to reduce the temperature and extinguish the fire. Specifically, the fire extinguishing apparatus 13 of the present embodiment employs a dual trigger to trigger fire extinguishing. Those skilled in the art will appreciate that the fire extinguishing device 13 of the present embodiment may alternatively be implemented. For example, the fire extinguishing device 13 may not be provided with a temperature sensing wire.
