Hot-pressed flame-retardant power supply protection system

Abstract

The invention discloses a hot-pressed flame-retardant power supply protection system and belongs to the field of power supplies. According to the system, lithium battery bodies are wrapped with a protection pad, so that the lithium battery bodies can be protected. When the lithium battery bodies are impacted by the outside, the protection pad can absorb a part of impact energy to prevent the shells of the lithium battery bodies from being broken; meanwhile, two adjacent lithium battery bodies are separated by the protection pad, chain reaction caused by thermal runaway of one lithium battery body is effectively avoided, then when the thermal runaway begins to occur, thermal expansion balls are expanded and enlarged by high-temperature heat so as to extrude a cflame retardant out of a capsule shell, so that expansion and spreading of fire can be effectively prevented after open fire occurs, absorption balls filled in the flame retardant can absorb leaked electrolyte, the amount of comburent is reduced to a certain extent, the spread of the fire is further prevented; and fire extinguishing particles release dry ice during battery combustion, absorb heat and sublimate into gas to isolate air, so that the spread of the fire is effectively prevented.

Description

technical field [0001] The invention relates to the field of power supplies, and more specifically, relates to a heat-pressing flame-retardant power supply protection system. Background technique [0002] The power supply is based on the principle of "magnetism generates electricity", which is generated by renewable energy sources such as hydraulic power, wind power, sea tide, dam water pressure difference, solar energy, and burning coal and oil residue. There are many types of power sources. With the development of microelectronics technology in the 20th century, miniaturized equipment is increasing day by day, which puts forward high requirements on power sources, and lithium batteries have entered a large-scale practical stage. [0003] The safety of lithium batteries has always been an urgent problem to be solved. The four main parts of a lithium battery are positive electrode material, negative electrode material, separator, and electrolyte. When dendrites or hand-shap...

AI Technical Summary

Problems solved by technology

[0004] At present, lithium batteries are widely used in new energy vehicles, which brings safety problems. Fire incidents occur from time to time. How to prevent the rapid spread of fire and win valuable escape time for personnel is a technical problem that has been being tackled. The existing technology There is also a corresponding fire extinguishing device in the vehicle, but its structure is relatively complicated, and the cost is relatively high, and it is easy to cause the failure of the fire extinguishing device when the vehicle collides, resulting in the failure of the fire extinguishing program to start normally and causing a safety accident.
