Abstract
The present invention proposes a kind of system of the included extinguishing device for battery, flame retardant selects a kind of fluorination liquid, selection toughness strong material in battery pack surface carries out entire package to battery pack, when battery monomer occurs when the temperature is excessively high in battery pack, fluorination liquid vaporizes after absorbing heat rapidly, and the first step inhibits the generation of explosion, and the gas after vaporization gathers in toughness material, equally completely cut off the entrance of air, equally inhibit the generation of explosion.The system can prevent the burning of battery and inhibit the explosion of battery, substantially reduce the risk of battery thermal runaway chain reaction caused by thermal runaway, have beneficial technique effect.
Description
Technical field
System more particularly to one kind the present invention relates to a kind of included extinguishing device are used to prevent battery in use
Burning or the system of explosion, belong to power battery technology field.
Background technology
With being becoming tight the day of traditional energy and the deterioration increasingly of environment, world community are all greatly developing new energy vapour
Vehicle.At present, the direction of countries in the world development new-energy automobile is concentrated mainly on hybrid vehicle and pure electric automobile, and electric
Pond is the main core drive component of hybrid vehicle and pure electric automobile.
The charge-discharge magnification of power battery is bigger, and battery temperature is raised faster.For battery monomer, fever is main
Chemical reaction occurred is internally sourced, if cannot export the heat of inside battery in time, will be made inside battery cell
Temperature drastically increases.Temperature is increased, accelerates chemical reaction, heat is caused to gather, explosion may finally occur or generates fire.
Also, electric vehicle inevitably will appear the accidents such as collision at work, and after collision, battery pack can generate explosion either fire
Calamity.
At present, the explosion of battery pack and the common extinguishing method of fire problem, which are utilized in battery pack babinet, places fire extinguishing
Material, and using alarm system, when fire occurs, alarm equipment alarm, extinguishing chemical automatic spraying in control system to electricity
In the babinet of pond, achieve the purpose that fire extinguishing.But when a fire, the circuit of system and monitoring system may fail, and
It cannot achieve the purpose that fire extinguishing, in addition, extinguishing chemical is it is possible that sprinkling is not uniform enough, it is impossible to achieve the purpose that fire extinguishing.
Application for a patent for invention number 201310302644.1 provides a kind of detected using flame detector and according to detecting
Fire signal start the electric vehicle self-extinguishing method of fire-smothering gear, this method relies on flame detector detection electricity
The fire behavior of pond case can detect in the serious consequence that open fire burning is caused after battery thermal runaway occurs and start fire extinguishing；
Complicated since battery case inner space is narrow, single flame detector detection mode, which easily causes, fails to report fire behavior；If
Battery case internal cell occurs resume combustion or causes thermal runaway extension, the then generation of multiple fire behavior of this method to subsequently occurring
Substantially there is no fire-extinguishing operations.
Invention content
In view of the above shortcomings of the prior art, the present invention provides a kind of improved battery fire extinguishing systems.The system uses
Two-step method is put out a fire, and can prevent the burning of battery, can also be inhibited the explosion of battery, be substantially reduced and draw electricity by thermal runaway
The risk of pond thermal runaway chain reaction protects the security of the lives and property of vehicle driver and passenger, has beneficial technique effect.
System of the present invention, main technical schemes are as follows：A kind of system of included extinguishing device for battery, packet
Include electrode line (4), negative line (5), battery modules (1), battery pack (2), flame retardant and explosion-proof lamp (3), it is characterised in that：
The flame retardant is arranged between the battery pack (2) and the explosion-proof lamp (3), the battery in the battery pack (2)
When monomer temperature is excessively high, the flame retardant absorbs heat gasification, inhibits the generation of explosion.
Preferably, the explosion-proof lamp (3) further suppresses explosion to the battery entire package.
Preferably, the flame retardant is fluorination liquid (6).
Preferably, the surfacing of the explosion-proof lamp (3) material strong for toughness.

Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only the part of the embodiment of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained without making creative work it is all its
His embodiment, shall fall within the protection scope of the present invention.
Referring to attached drawing 1, battery pack structure provided by the invention, including electrode line (4), negative line (5), battery modules (1),
Battery pack (2) and the explosion-proof lamp (3) set outside battery pack (2), the explosion-proof lamp (3) may be designed as battery pack (2)
Surfacing or encapsulated as other one layer of protection outside the battery pack (2)；Battery pack (2) is to the battery modules
(1) entire package, the explosion-proof lamp (3) can also preferably be integrally formed battery pack (2) entire package in encapsulation, this
The explosion-proof lamp (3) is not arranged to the structure with hole or hole by kind structure, can completely cut off the entrance of air, is further pressed down
It has made explosion to occur, for preventing the effect highly significant of cells burst or explosion.The battery pack (2) and/or explosion-proof lamp (3)
Surfacing can be the strong material of toughness or preferably nonflammable and strong toughness material, those skilled in the art can
It is expected that the toughness refers to provide when being subjected to expected use condition by force any material of intensity needed for structural intergrity, institute
It is preferably metal foil, plastic-aluminum combined membrane material, fluoropolymer etc. to state surfacing.
Referring to attached drawing 2, the system of included extinguishing device provided by the invention, flame retardant is non-solid in the system or semisolid
Form, but preferably fluorination liquid (6) can be obviously improved the efficiency of fire extinguishing；The fluorination liquid (6) is arranged on the battery pack
(2) between the explosion-proof lamp (3), when the battery monomer temperature in the battery pack (2) is excessively high, the fluorination liquid
(6) heat gasification, the quick generation for inhibiting explosion are absorbed；Simultaneously as entirety of the explosion-proof lamp (3) to battery pack (2)
Packaging so that the gas after gasification gathers in the explosion-proof lamp (3), has completely cut off the entrance of air, has further suppressed quick-fried
It is fried to occur.
