Description
Technical field
The invention belongs to technical field of new energy, and in particular to a kind of new energy car battery packet feeder.
Background technique
Compared with orthodox car, new-energy automobile also has in work new-energy automobile other than it can get rid of and rely on petroleum
The advantages of uncontaminated gases are discharged when making, and protect urban environment.Battery pack is the critical component of new-energy automobile, quality it is good
It is bad to directly influence new-energy automobile service life and safety.New-energy automobile in use, occurs combustion on fire at present
, there is one of the cause of accident in burning accident, is that battery pack internal firefighting gas concentration is not high enough, when in battery pack thermal runaway
When, the reaction of battery core internal chemical ruptures battery core shell or protective film, and battery core inner material is excessive, and the substance is in high-temperature condition
Under, continue to react with battery core external oxygen, expands combustion range.
New energy car battery packet in process of production can be full of fire extinguishing property gas (such as carbon dioxide, nitrogen or other
Have the gas of fire-extinguishing function concurrently to battery core), but battery pack is in use, will receive in ambient temperature or the battery pack course of work
The heat of generation influences, and generates pressure difference with extraneous inside battery pack, when battery pack external pressure is greater than internal pressure, air
It will be entered inside battery pack at leisure by the position of weak seal, so that battery pack internal firefighting gas concentration is reduced,
Influence extinguishing effect.
Summary of the invention
The purpose of the present invention is to provide a kind of new energy car battery packet feeders, by new energy car battery
Pack housing (i.e. battery case) installs a kind of battery pack feeder, when battery pack extraneous gas pressure be greater than it is internal when, gas supply dress
Fire-suppressant gas will be automatically generated by setting, and be filled into inside battery pack, be consistent gas pressure intensity inside and outside battery pack substantially, thus
It avoids outside air from entering inside battery pack and reduce fire-suppressant gas concentration, and reduces battery pack sealing strip and pressed for a long time
Strong poor influence and damage.
To achieve the goals above, technical scheme is as follows.
A kind of new energy car battery packet feeder, including memory, film, baffle and collision mat, film setting exist
On the outside of memory；Baffle is arranged in film outside；Collision mat is arranged outside memory；Memory inside is equipped with the first storage silo
With the second storage silo, it is connected between the first storage silo and the second storage silo equipped with pipeline；First storage silo and the second storage silo
Side wall is equipped with hole；Blanking cover is equipped in hole on second storage silo side wall.
Further, gas generant is placed in the first storage silo；Liquid gas hair is placed in second storage silo
Biomass.
Further, it is that phosphoric acid solution or other liquid, memory are deposited that substance, which occurs, for the liquid gas stored in memory
Another gas generant of storage is non-gaseous material, such as solid or liquid.
In the device, film is easily deformed by there is tough and soft material (such as polyurethane) to be made.Memory has one
Determine intensity, it is not easy to deform, there are two storage silo, there is hole in each storehouse for the inside, and gas generant can be put into through hole and be deposited
In warehouse.When battery pack feeder is fixed to battery pack, the second storage silo hole of substance occurs for storage liquid gas by blanking cover
It is stifled tight, and another storage silo Kong Nengrang gas frees in and out, when battery pack external pressure is higher than internal pressure, film can be past
Substance (such as phosphoric acid solution) occurs for the deformation of battery pack internal direction, the liquid gas for squeezing memory, and gas generant can lead to
Piping flows to another storage silo of memory, and rises with another gas generant (such as sodium carbonate) stored in the storehouse
Reaction, anger fire extinguishing property gas (such as carbon dioxide), gas is filled by the hole which is communicated by memory with battery pack
In battery pack, so that battery pack internal pressure is gradually increased, so as to be consistent substantially outside battery pack with internal pressure, in electricity
During pond packet internal pressure increases, battery pack internal gas can flow to memory storage liquid gas by the pipeline of memory
Body occurs to reduce deformation of thin membrane amount in the storehouse of substance, or even reaches and deform preceding shape.When battery pack external pressure is than internal pressure
Strong hour, film are stopped toward battery pack dimensional deformation by baffle, it may be preferable that and battery case installation cooling gas check valve is used cooperatively,
Battery pack internal gas is consistent pressure inside and outside battery pack, which can only by gas unidirectional valve exhaust body
Make battery pack internal gas toward outlet, gas cannot be made to be inhaled inward from outer toward battery pack.
In the device, battery pack feeder has film, memory and gas generant, when battery pack external pressure is big
When internal, external pressure can make tough and soft deformation of thin membrane, and substance occurs for the liquid gas of the one of memory block of memory
After being squeezed, another memory block, the gas generant chemically reactive of the area Bing Yugai storage, production are flowed to by pipeline
Fire extinguishing property gas (fire extinguishing property gas refers to the gas for having fire-extinguishing function concurrently to battery core, including but not limited to carbon dioxide and nitrogen),
Fire extinguishing property gas flows to inside battery pack and increases internal pressure, makes to be consistent substantially outside battery pack with internal pressure, by
It is fire extinguishing property gas in being filled into the gas come, therefore battery pack internal firefighting gas concentration will not be reduced
Invention has the beneficial effects that: the invention can be such that the battery pack internal firefighting gas for being mounted with the device is maintained at
High concentration state；It can be reduced pressure difference inside and outside the battery pack of installation battery pack feeder, it is close to battery pack to reduce pressure difference
The destruction of seal structure；In the device, aperture in structure, even if not using transparent material, it can also be seen that object occurs for liquid gas
If after it is installed to battery pack by matter service condition, substance can occur in the liquid gas of the battery pack external observation device makes
With situation, the timely replacement if having used；This new energy car battery packet feeder course of work does not need electrical part control,
Start automatically under necessary environment.New energy car battery packet feeder structure of the invention is relatively independent, if there is damage
Or the reasons such as to have used to need replaceable for gas generant, the present invention can judge new energy car battery packet outside battery pack
Whether the gas generant of feeder has used, convenient and efficient if can be individually replaced using complete.
