Abstract
The utility model provides an anti-explosion battery pack and vehicles or ships using thereof. The anti-explosion battery pack comprises a battery module consisting of a plurality of battery units and a battery box used for containing the batter module, an accessory box communicated with the inner portion of the battery box is arranged outside the batter box, and a nitrogen generating device is arranged inside the accessory box. The anti-explosion battery pack can prevent the battery pack from combusting and avoid the causing of a greater damage in an extreme usage environment such as inside a mine crater, can further prevent the battery pack from exploding, and can effectively guarantee the safety of a passenger.
Description
Technical field
The utility model relates to a kind of battery pack, especially a kind of anti-explosion battery group.
Background technology
In today of scientific and technical high speed development, motor vehicle is no longer a dream, purely and simply be presented on common people in face of, but because the operate power of motor vehicle is higher, so also unusually harsh to the requirement of the power of electrokinetic cell and energy.
For satisfying the requirement of power and energy, when really relying on fully, electric motor car then needs hundreds of is saved the cell connection in series-parallel when battery-operated, generally be packaged into a battery module by the parallel connection of dozens of cell, again several battery modules are connected into a battery pack, at last battery pack is inserted in the battery case, because repeating to discharge and recharge, battery can produce very large heat in running, so for the heat dissipation problem that solves battery in general battery case all be multiple duct, many louvres structure, but such design can bring the consequence that much do not work: when battery is under the extreme operational environment because the generation of the phenomenons such as short circuit can be easy to touch airborne oxygen or other imflammable gas cause more serious consequence, and owing to burning occurs in battery case is difficult to thoroughly eliminate kindling material with Fire extinguisher from the battery case outside.
The utility model content
The purpose of this utility model provides a kind of battery pack that can effectively prevent the battery pack of burning even blast occurs.
For reaching above-mentioned purpose, the utility model provides a kind of anti-explosion battery group, comprise the battery module that formed by several battery units and and hold the battery case of battery module, the attached case that described battery case outer setting communicates with battery case inside arranges nitrogen gas generating device in the described attached case.
Attached case except with position that battery case inside communicates seal with respect to the outside, attached case is exactly the position that communicates with battery case with extraneous unique outlet, can so that attached case to battery case forced draft.
The nitrogen gas generating device that arranges in the attached case discharges nitrogen, enters battery case by unique outlet, and with the Bas Discharged in the battery case, so that the minimizing that contacts of battery pack and air.
As preferably, in the described battery case one-way slabs is set, so that attached case is with respect to the battery case one-way conduction.
One-way slabs is set in battery case can effectively stops the gas in the battery case to enter attached case, strengthen the effect that air is discharged from battery case.
As preferably, described nitrogen gas generating device is selected from one or both in nitrogen compressed tanks and the nitrogen gas generator.
The nitrogen compressed tanks is set, the portability that not only can guarantee explosion-proof effect but also guarantee to carry in the portable battery module; Use nitrogen gas generator constantly to produce nitrogen at oversize vehicle or steamer, be full of battery pack.
Nitrogen gas generator, air separation by PSA nitrogen processed (being called for short P.S.A nitrogen processed) is a kind of advanced person's gas separation, take high-quality import carbon molecular sieve (CMS) as adsorbent, pressure-variable adsorption principle (PSA) separation air is produced highly purified nitrogen under the employing normal temperature.
Oxygen, two kinds of gas molecules of nitrogen are in the lip-deep diffusion rate difference of molecular sieve, the gas molecule that diameter is less (O2) diffusion rate is very fast, the more carbon molecular sieve micropore that enters, the gas molecule that diameter is larger (N2) diffusion rate is slower, enters the carbon molecular sieve micropore less.Utilize carbon molecular sieve to this Selective adsorption difference of nitrogen and oxygen, cause interior oxygen of short time in the Adsorption Phase enrichment, nitrogen is in the enrichment of gas phase, and so oxygen nitrogen separates, and obtains gas phase enrichment thing nitrogen under the PSA condition.
As preferably, on the described nitrogen compressed tanks control valve is set.
In the nitrogen compressed tanks control valve being set can discharge nitrogen fast in battery pack needs or abnormal, nitrogen is squeezed in the battery case from attached case.
As preferably, at least a in the described battery case in set temperature transducer, Smoke Sensor and the organic probe.
Set temperature transducer, Smoke Sensor and organic probe can in due course so that the control valve on the nitrogen compressed tanks is opened, eliminate danger thereby discharge nitrogen in the battery case.
The utility model also comprises a kind of vehicle, comprises above-mentioned any anti-explosion battery group.
The utility model also comprises a kind of boats and ships, comprises above-mentioned any anti-explosion battery group.
Used after the technical scheme that the utility model provides, can stop the battery pack burning, avoid in extreme environment for use (in the pit) to cause larger harm, can prevent that further battery pack from blasting, effectively guaranteed the safety of passenger.
Description of drawings
Fig. 1 is the structural representation of anti-explosion battery group.
Wherein 1, battery case, 2, attached case, 21, nitrogen gas generating device, 3, one-way slabs.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
As shown in Figure 1, the anti-explosion battery group comprise the battery module that formed by several battery units and and hold the battery case 1 of battery module, the attached case 2 that described battery case 1 outer setting communicates with battery case 1 inside, attached case 2 except with seal with respect to space outerpace battery case 1 inside communicates, the described attached case 2 interior nitrogen gas generating devices 21 that arrange, nitrogen gas generating device 21 is selected the nitrogen compressed tanks, and an one-way slabs 3 is installed at the position that communicates with attached case 2 inside in battery case 1.
In the nitrogen compressed tanks control valve is set, battery case 1 is interior to arrange organic probe, when battery case 1 interior generation battery drain, organic probe detection sends control signal so that the control valve on the nitrogen compressed tanks is opened after the electrolyte that leaks, control valve is opened control nitrogen compressed tanks and is discharged fast nitrogen and wash one-way slabs 3 open, forming malleation nitrogen with respect to battery case 1 this moment ventilates, the Bas Discharged in the battery case 1, so that be full of nitrogen in the battery case 1, burning things which may cause a fire disaster and oxygen is isolated, thus reach the explosion-proof purpose of fire extinguishing.
As shown in Figure 1, the anti-explosion battery group comprise the battery module that formed by several battery units and and hold the battery case 1 of battery module, the attached case 2 that described battery case 1 outer setting communicates with battery case 1 inside, attached case 2 except with seal with respect to space outerpace battery case 1 inside communicates, the described attached case 2 interior nitrogen gas generating devices 21 that arrange, nitrogen gas generating device 21 is selected small-sized PSA nitrogen making machine, and an one-way slabs 3 is installed at the position that communicates with attached case 2 inside in battery case 1.
