Abstract
A kind of heat-insulating, fire-preventing anti-explosion battery group, including Battery case, it is set to the intracorporal battery of battery case, the Battery case is equipped with heat-insulating, fire-preventing layer, extends explosion-proof exhausting pipe on Battery case, and anti-explosion exhaust pipe end is equipped with waterproof vent valve.The advantages of battery pack of the present invention is: when battery catches fire, smoldering, burning, the toxic and harmful gas generated can be discharged into the position of a safety by explosion-proof exhausting pipe, avoid the internal pressure of Battery case excessive and bring risk of explosion.Waterproof vent valve is arranged in anti-explosion exhaust pipe end, the exchange of oxygen passes through waterproof vent valve and explosion-proof exhausting pipe in Battery case, it is eventually transferred into Battery case, but oxygen delivery rate, transmission capacity are limited, it thus can reduce and control intensity of a fire size, in oxygen-deficient situation, flare will automatic distinguishing, to ensure that the security performance of battery pack.
Description
Technical field
The present invention relates to the security fields of battery pack, specifically a kind of heat-insulating, fire-preventing anti-explosion battery group.
Background technique
It is increasingly serious with energy and environmental problem, in industrial policies such as energy-saving and emission-reduction, green credit, green security and
Under the promotion in market, electric car is gradually causing the attention of society and government, and electric car will also become future automobile
The big branch of the one of industry.Electric car core component first is that battery pack.And the security performance of battery pack is to determine that the system is
No available key technology.
With advances in technology, the application field of lithium-ion power battery system is more and more extensive, to lithium ion power electricity
The performance of cell system and the requirement of safety are also higher and higher.For the requirement for meeting battery power and energy, when electric vehicle according to
When by battery driving, needs several hundred section single batteries carrying out series and parallel, be generally packaged into one by dozens of single battery parallel connection
A battery module, then several battery modules are connected into a battery pack, finally battery pack is placed in Battery case.
In the prior art, battery pack is not directed to the emergency cases such as on fire, burning and is equipped with corresponding processing structure and arranges
It applies, when battery pack is under extreme working environment, the battery pack due to caused by short circuit, thermal runaway etc. is smoldered on fire, explosion, combustion
When phenomena such as burning, the excessively high combustible combustion on fire induced near Battery case and vehicle of Battery case surface temperature often will lead to
It burns, so as to cause electric vehicle pyrophoricity accident.
Therefore, it is necessary to be further improved.
Summary of the invention
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, and provide a kind of heat-insulating, fire-preventing anti-explosion battery
Group has the function of that heat-insulating, fire-preventing is explosion-proof, guarantees the safety of battery pack.
The object of the present invention is achieved like this:
A kind of heat-insulating, fire-preventing anti-explosion battery group, including Battery case, it is set to the intracorporal battery of battery case, the battery case
Body is equipped with heat-insulating, fire-preventing layer, extends explosion-proof exhausting pipe on Battery case, and anti-explosion exhaust pipe end is equipped with waterproof vent valve.
The outside and/or inside of Battery case is arranged in the heat-insulating, fire-preventing layer.
The explosion-proof exhausting pipe is located at the top of Battery case side.
The heat-insulating, fire-preventing layer is filled by fire protection flame retarding heat-barrier material.
The heat-insulating, fire-preventing layer with a thickness of 2~50mm.
The heatproof of the heat-insulating, fire-preventing layer is at 500~1500 DEG C.
The battery is single battery.
The battery is made of two or more sub- batteries.
Beneficial effects of the present invention are as follows:
When battery catches fire, smoldering, burning, the toxic and harmful gas generated can be discharged into one by explosion-proof exhausting pipe
The position of safety, avoids the internal pressure of Battery case excessive and brings risk of explosion.Waterproof vent valve is arranged in anti-explosion exhaust pipe end,
The exchange of oxygen is eventually transferred into Battery case by waterproof vent valve and explosion-proof exhausting pipe in Battery case, but oxygen passes
It is limited to pass rate, transmission capacity, thus can reduce and control intensity of a fire size, in oxygen-deficient situation, flare will be automatic
Extinguish, to ensure that the security performance of battery pack.
Detailed description of the invention
Fig. 1 is the cross-sectional view of one embodiment of the invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1, this heat-insulating, fire-preventing anti-explosion battery group, including Battery case 2, the battery being set in Battery case 21,
The Battery case 2 is equipped with heat-insulating, fire-preventing layer 3, and the on fire, out-of-control conditions such as smolder, burn occur in extreme circumstances for battery pack
Under, heat-insulating, fire-preventing layer 3 can guarantee that 2 surface of Battery case still maintains within the scope of controllable temperature, will not be because of Battery case 2
The excessively high induction Battery case 2 of surface temperature and combustible catching fire near vehicle, so as to cause electric vehicle pyrophoricity accident.
Extend explosion-proof exhausting pipe 4 on Battery case 2, when battery catches fire, smoldering, burning, what is generated is poisonous and harmful
Gas can be discharged into the position of a safety by explosion-proof exhausting pipe 4, avoid the internal pressure of Battery case 2 excessive and bring explosion wind
Danger.
4 end of explosion-proof exhausting pipe is equipped with waterproof vent valve 5, in Battery case 2 exchange of oxygen by waterproof vent valve 5 and
Explosion-proof exhausting pipe 4 is eventually transferred into Battery case 2, but oxygen delivery rate, transmission capacity are limited, thus can be reduced and be controlled
Intensity of a fire size processed, in oxygen-deficient situation, flare will automatic distinguishing, to ensure that the security performance of battery pack.
Further, the outside 21 and/or inside 22 of Battery case 2 is arranged in the heat-insulating, fire-preventing layer 3.
Further, the explosion-proof exhausting pipe 4 is located at the top of 2 side of Battery case.
Further, the heat-insulating, fire-preventing layer 3 is filled by fire protection flame retarding heat-barrier material.
Further, the heat-insulating, fire-preventing layer 3 with a thickness of 2~50mm.
Further, the heatproof of the heat-insulating, fire-preventing layer 3 is at 500~1500 DEG C.
Further, the battery 1 is single battery, alternatively, the battery 1 is by two or more sub- battery structures
At.
The above disclosure is only a preferred embodiment of the invention, rather than limits claim of the invention with this
