2013/0143077 A1 of document US describes a kind of lithium ion battery.Such battery has shell flexible, institute Stating shell can have one or more openings for exhaust.
Summary of the invention
Subject of the present invention is battery system, and the battery system has the battery module with multiple battery lists pond, institute It states battery list pond and is respectively provided at least one and be arranged in the intracorporal single pool unit of single pond shell, wherein single pond shell is respectively provided with and is used for The row that the emission (Entgasungsemission) especially formed in single pond shell in case of a fault is exhausted Gas valve, and which provided for by emission derived from battery system exhaust collector, the exhaust collector have with The opening of exhaust valve connection, which is characterized in that exhaust collector can be deformed because of emission, so that by the exhaust collector The volume surrounded can increase.
Such battery system allows to be exhausted with improvement, with regard to cheap manufacturability and especially space-saving install This is sayed by allowing reliable exhaust and the export of emission to realize.
For this purpose, battery system includes the battery module with multiple battery lists pond first, battery list pond is respectively provided with At least one is arranged in the intracorporal single pool unit of shell.Therefore battery module includes multiple battery lists pond or by multiple battery lists pond structure It builds, battery list pond can be connected in series or in parallel in a way known.Battery list pond is respectively provided with single pond shell herein Body arranges one or more single pool units in single pond shell.Here, setting one single pool unit includes with this field Multiple single pool units are equally arranged in the intelligible mode of technical staff in shell.Single pool unit can be substantially such as the prior art Such as known lithium ion list pond constructs like that, and is for example configured to the element of winding (Wicklungselement).
In order in case of a fault can be by formation interior inside unit, such as gas that is discussed in detail above from electricity Chi Danchi export, single pond shell or the multiple single pond shells being arranged in module, which have, is for example configured to substantially known break Split the exhaust valve of film.Here, the gas or at least partially gaseous mixture that hereinafter will escape out are together with its composition The pressure of part and its characteristic, i.e., the temperature and raising that especially improve is collectively referred to as emission.
For following situations, that is, exist in one or more battery list pond and be related to what emission was overflowed from battery list pond Fault condition, emission should not only be exported from battery list pond, but also should with limiting from battery system and in an advantageous manner from It is equipped with the equipment export of battery system.For example, emission can be guided out from electric motor or by electrically driven vehicles.For This, in aforementioned battery system setting for by emission derived from battery system exhaust collector.Therefore, this kind of exhaust is received Storage can be for example specifically configured or be arranged as pipeline or channel or pipe-line system or channel system, and emission is purposeful Ground and restriction ground export and from battery system to the guidance of the exhaust position of restriction.For example, can be used for will be harmful for exhaust collector Gas is not directed in vehicle passenger cabin but is directed in vehicle-periphery.Here, exhaust collector can for example be used for by Emission is opened from battery system guidance.In order to which emission to be directed in exhaust passage from battery list pond, the exhaust passage can With the quantity according to single pond shell or exhaust valve with the opening of suitable quantity, the exhaust of the opening and battery list pond Valve or single pond shell connect to pressure seal in an advantageous manner.Therefore be positioned so as to emission passes through exhaust valve to opening It can be flowed into exhaust collector with opening.The connection of pressure seal is and if so, can also mean that emission is flowed into Without the risk of uncontrolled spilling in exhaust collector.
For aforementioned battery system, provide herein: exhaust collector can deform because of emission, for example deployable or can Extend, so that can be increased or may expand by the volume that the exhaust collector is surrounded.Such design scheme is relative to existing skill Especially rigid or the unmodifiable exhaust collector in terms of its volume solution party is arranged in known solution in art Method particularly has the advantages that significant.
By the way that the exhaust collector constructed as previously mentioned is arranged, this exhaust collector is electric from one or more in emission Chi Danchi can be deformed when overflowing or be extended or be unfolded, so that the emission all occurred can pass through exhaust collector without problems Export.
Thus can realize: exhaust collector can be compactly arranged in single pond under the desired working condition of battery system On shell, and required volume is only constituted in case of need.It is especially saved spatially to exhaust gas collection thus, it is possible to realize Device is arranged, wherein big cross section however can be still realized without problems, without for good and all maintaining enough structures Space, or spatially demanding collector do not cause it is difficult to install.The big cross section of exhaust collector can be herein It is advantageous, so as to dynamically export the emission under pressure.
Here, the deformation of exhaust collector and the concomitantly volume by being surrounded by exhaust collector can be passed through Increase even generate without problems relative to rigidity arrangement increase cross section, because of for example preceding institute in the cross section of the increase It states and does not need to be permanently present.As a result, compared in the case where lesser cross section, since ideal gas law can make Pressure is relatively smaller and temperature is relatively lower, thus the load occurred especially as temperature and pressure for the material more It is low.
By saving rigid collector and therefore can also realize other advantages by reducing rigid element, that is, can be with Prevent the generation of following situations: because of the size and quality of such rigid element, in the operation of dynamic vehicle, unrestricted Mobile application in for example in electrically driven vehicles, the displacement of component, which will lead to sealing system, has high carry in interface Lotus.
Furthermore it can only exhaust collector be made of flexible material, and actual battery list pond or its shell are then by hard And for example formed by the shell of rigidity, this will not negatively affect the safety in practical list pond.Because furthermore passing through stable list Pond shell can also be effectively prevented the mechanical failure in single pond.
Here, the material for being particularly well suited as exhaust collector is polymer resistant to high temperature, i.e., it is steady for emission Fixed polymer, such as polyethylene terephthalate or stainless steel, such as SUS304, the material for example can have pleat Wrinkle, the fold can be unfolded similar to bellows (Blasebalg).Such material can be by high flexibility and high stability And especially light weight is integrated in one.
In short, aforementioned battery system can therefore realize it is cheap, space-saving, light weight and reliable, be used for The exhaust system being vented in the case where battery list pond is broken down.
In a kind of frame of design scheme, exhaust collector can have at least one such region, region tool There is the shape inwardly to arch upward and the region can be converted into the region with the shape to arch upward outward by emission.Design side herein In case, one of a plurality of areas or multiple regions are therefore in the desired operation of battery system in inside or protrusion shape Shape.By emission, particularly by the pressure of emission, may be implemented herein corresponding region or multiple corresponding regions to Outer deformation and the shape for being therefore in recess.Thus Absorbing hydraulic pulsation without problems can be realized particularly, because passing through exhaust The spilling energy of the deformation of collector or the deformation at least one region correspondingly formed, emission is absorbed or is applied use In deformation or consume for deforming.Here, can for example but unrestrictedly on each battery list pond or respectively with single pond shell The region of protrusion is respectively present on the adjacent battery list pond of exhaust valve.It but particularly, in this construction in principle can also be with So that exhaust collector is formed by metal as described above herein.Metal can for example be configured to metal plate, desired by realizing Deformability.
In this design scheme, therefore can particularly effectively Absorbing hydraulic pulsation.Thus, it is possible to evade following disadvantage, That is, being absorbed with only having ready conditions earthquake state by the stiff case surrounded up to 10 bars due to battery list Chi Lianxu according to the prior art Compression shock caused by being vented.It therefore can be to avoid: can go out when battery list pond is vented since very dynamic pressure is established Show the deformation of housing parts, the sealing element between housing parts not can compensate for or only can difficulty compensate the change of the housing parts Shape.Therefore, problems not bery appear in the exhaust collector of foregoing soft especially not bery occur it is in this configuration but former It is also not bery appeared in exhaust collector according to the present invention on then.
It is that exhaust collector can at least partly can be deformed by emission and/or molten in another design scheme The material of change surrounds.Here, the material can be directly by being placed on exhaust collector or being spaced apart with the exhaust collector. In addition, corresponding material can be disposed adjacently completely around exhaust collector or only partially with exhaust collector.This Material can be deformed herein due to emission, particularly compressed or melted by emission.Deformation herein can be special Ground is occurred by the pressure of emission, and melting can particularly lead to by the temperature of emission and concomitantly The temperature for crossing exhaust collector occurs.Thus, it is possible to realize that exhaust collector occupies previously shared by the material in exhaust According to space.Thus, it is possible to particularly stable arrangement is completed under extra high compactedness, it is described to arrange the not row of negatively affecting The volume of gas collector increases.
For example, previous materials can be foamed material and thus deformable or compressible.It in this design scheme, such as can To use the foamed plastics being for example made of polyurethane material (Schaumstoffe).
In terms of fusible property, the fusing point of such material may be at or lower than emission temperature, thus not only can be with It realizes the compression of material and the fusing of material may be implemented.The expansion of exhaust collector can also be further improved as a result,. Material with corresponding fusing point is also possible to aforementioned polyurethane material or polyurethane foam or other foamed plastics.
This class A foam A or foamed plastics can also provide other advantages, i.e., the described foam or foamed plastics form insulation effect Fruit, especially thermal insulation effect so as to save other insulating materials at this location, or can significantly reduce the insulation The use of material.Therefore, particularly in this design scheme, the use of battery system especially can be in following application advantageous , i.e., the application of the described battery system by thermal insulation or should be configured to double-deck and in order to insulate with coldplate.
Can be set protection element in the frame of another design scheme, the protection element in exhaust at least partly It is in the front for the sealing element being arranged between exhaust collector and single pond shell.Here, sealing element can be directly arranged at list Between pond shell and exhaust collector, or it is arranged in another housing parts and exhaust collector or single pond shell indirectly and herein Between body, wherein another housing parts are arranged between exhaust collector and single pond shell.But principle upper seal is in sky Between on be arranged between single pond shell and exhaust collector.
Such protection element can be further improved the structure being made of for example single pond shell of housing parts or module housing Leakproofness and stability.It in this design scheme, therefore can react in particular for following problem, i.e., due to exhaust cycle Between compression shock, temperature and chemicals combination so that single pond shell is for example highly difficult with the leakproofness of exhaust collector.This Outside, the sealing element between single pond and collector often includes rubber or another plastics, and by top load and thus in exhaust Blow-by can potentially be become.This problem in order to prevent is provided with protection element in this design scheme.
It is that protection element may, for example, be metal and/or be configured to membranaceous, and it is placed in or is fixed on other than sealing element Between battery list pond and exhaust collector.For example, protection element can be fixed between single Chi Gai and module lid.Protection element exists This is so constructed, it is allowed to place or open upwards when single pond is vented, and therefore outward by being placed on exhaust pathway and It can protect and the additionally component of the place of sealing at which, especially sealing element.Therefore, sealing can protect by protection element Furthermore part can prevent chaff interferent to be flowed into the space between single Chi Gai and sealing element not by the damage of temperature and chemicals With in collector and sealing element is degenerated.In principle, the setting of such protection element herein can be such as common rubber seal Part uses like that, and for example bridges the region between list Chi Gai and collector.
In the frame of another design scheme, exhaust collector can be connected by bonding or by also referred to as clamping connection Clamping lock be fastened on housing parts.Particularly, such connection can be in rigid housing parts and housing section flexible Reliable sealing and lasting connection are formed in the combination of part.Here, aforementioned connection type can be produced inexpensively and simply be made It makes.
Exhaust collector is sealingly connected on housing parts as achievable in previous designs scheme, example Such as be sealingly connected on module housing or single pond shell be battery system reliability service particularly advantageous precondition.Especially Ground because the pernicious gas of discharge line (Ableitungen) and corresponding battery component seal be connected to for example using It may be implemented not run battery system jeopardously for the health of Vehicular occupant when in vehicle.Therefore, can particularly guarantee: In Toxic pernicious gas is not entered in passenger compartment but is exported in environment when exhaust.
In the frame of another design scheme, battery list pond and exhaust collector can be at least partially by shells flexible It is surrounded.Here, it may be stipulated that: the component of battery system is in single pond level, module level or group level by such shell packet It encloses, wherein being especially flexible connection and can be fluctuated with compensation pressure by corresponding pressure seal.Such as it is configured to film Different physical features on the whole, such as different thermal conductivity may be implemented in the combination of different materials of shell herein.
" shell flexible " it can be appreciated that such a shell, the shell is for example due to emission is flowed into shell Such as it can extend or be unfolded and therefore its volume surrounded can increase.In this design scheme, it may be implemented especially may be used Protect ambient enviroment from the destruction of the pernicious gas of exhaust Shi Huicong battery list pond evolution by ground.Specifically, designing herein In scheme, the sealing element of the subassembly of the sealing element, particularly battery module or entire battery system of the subassembly of battery system It can be realized in for example elastic form flexible by the shell with flexible material, battery is being installed to such as vehicle The ductility of the subassembly is reduced when in narrow structure space.Therefore, compression shock when battery list pond is vented can be with It is dynamically absorbed by the shell flexible surrounded, especially for following situations, that is, between battery list pond and exhaust collector In the presence of or produce undesirable blow-by.
The advantages of such shell flexible, may is that the shell must only have its maximum swelling under exhaust condition Degree, and can significantly reduce shell described in its dilation only by emptying during installation needs to wrap up and seal slightly larger than it Actual module housing or shell grid (Geh usegitter).Thus, it is possible to obtain battery system or its subassembly, institute Subassembly is stated with the smallest possible volume expansions degree and therefore can be readily and inexpensively installed in spatially limited structure In space, in such as motor vehicle.Then under exhaust situation, for example, motor vehicle or it is close to motor vehicle, be typically due to technology Unusable structure space may be used as gas held portion or for guiding system reason in normal operation.
For example, shell flexible and exhaust collector can be by thermal expansion coefficients same thickness and/or having the same It is constituted with the flexible material of mechanical swelling coefficient, such as shell and exhaust collector can be constructed by identical material.It is soft Property shell can be made of herein polymer resistant to high temperature, i.e., by stable polymer for emission, it is for example poly- to benzene Dioctyl phthalate second diester.Alternatively, shell can be by constituting, and for example as hereinbefore referred to stainless steel described in exhaust collector With fold, the fold can be unfolded similar to bellows.The connection or sealing of material can for example by bonding, welding or Vulcanization is realized.Once such as module housing is especially had rigid inner shell by the shell with exhaust passage or exhaust collector Body structure is surrounded, then can be mechanically pressed onto component flexible easily on especially latticed inner shell and will be flexible Shell emptying.The emptying can have been completed in the manufacture of battery system.
By being formed by the negative pressure of such as 0.8ba, such as the exhaust collector with exhaust hose can be forced into On all exhaust ports of single pond shell, thus to ambient enviroment, for example to vehicle-periphery itself seals connection.It is soft Property component be retracted to the internal structure size given in advance by rigidity together, and negative pressure interconnecting piece is also being sealed it Keep these sizes afterwards and after removing negative pressure pump.By this method, battery system or its subassembly can obtain minimum possible Size.
In accident from one or more battery list pond be vented when, be formed by until 10ba compression shock first It is pressed onto the opening in exhaust collector by exhaust valve.Exhaust collector with exhaust passage herein with shell flexible Hermetic connect.This means that such as bag configuration flexible that battery pack or battery module and exhaust apparatus are sealed is outer Shell surrounds, and the exhaust passage or multiple exhaust passages of exhaust collector have been guided by the shell.For example, only exhaust collector It can have desired opening leading to ambient enviroment, for example leading to the ambient enviroment of motor vehicle.
It is that this has apparent advantage is that the opening in exhaust collector does not need airtightly to connect with single pond shell or example It there are the reliable export that when blow-by, can also realize emission or is received such as between exhaust collector and single pond shell, because For another exhaust pathway is not present for emission.
Shell and exhaust collector flexible can flexibly expand to the max architecture defined by such as vehicle structure Spatially.Therefore, the pernicious gas to issue from battery list pond or multiple battery lists pond provides more normal than rigid structure form Advise the bigger expansion space of exhaust system.By bigger expansion possibility, the pressure and temperature of admixture of gas becomes only Height, therefore material flexible can usually be resistant to occurred load without problems.It therefore, can be abundant in this design scheme It utilizes " inoperative (totes) volume ", i.e., the substantially unemployed volume in the ambient enviroment of battery system, and obtains It must be used for the volume of emission.
Here, the stability increased can also be accomplished by the following way: being arranged in the ambient enviroment of battery system Such equipment, under swelling state, i.e. for instance in expansion or in the state of extension exhaust collector and/or flexibility Shell can be by being put into the equipment.The equipment herein can preferably rigidity and be for example arranged in when battery system When arranging in luggage compartment or neighboringly with the luggage compartment, the equipment can be for example made of vehicle part, such as by vehicle The inner wall of luggage compartment is constituted.Thus, it is possible to reliably receive and protect since emission for example passes through packaging structure (Verpackungsarchitektur) component flexible that can be unfolded or extend, it is possible thereby to obtain increased over-voltage tolerance Property.
Here, may further specify that: utilizing sealing element, example existing for when necessary, by the connector that shell flexible guides It is sealed such as the sealing ring of bonding, thereby while so still can produce air-tightness.If such as cable etc. is by the connector packet Enclose, such as cable is surrounded by module or the terminal in each battery list pond, then the cable particularly can be set inside the shell or It formula can also be completely wound around or with the construction of helical wire form is set, thus the cable itself and flexibility in exhaust Shell can also extend or increase together its space length.
In the frame of another design scheme, on the shell, such as on the surface of shell being directed toward in housing interior volume On, it is provided with a kind of material, which has bigger thermal conductivity compared to the material of shell.For example, good using having In the case where the adhesive of thermal conductivity, this material can be bonded or be welded with shell.Thus, it is possible to utilize particularly preferred thermal connection Battery list pond is arranged in cooling equipment, for example arranges on the cooling plate by realization, and outside wherein cooling equipment can be arranged in Except shell.Thus, it is possible to prevent cooling equipment from being soaked inside the shell by dew and therefore negatively affecting battery list pond.In addition, It can simplify the operation of battery system or module.In addition, can particularly be mended depending on structure type in this design scheme Height tolerance is repaid, and the thermal connection in cooling equipment can be improved.
In the frame of another design scheme, shell flexible can have exhaust valve, and the exhaust valve is in shell Predetermined interior pressure open.For example, such exhaust valve may be constructed such that splitter (Sollbruchstelle). Further security income may be implemented by such exhaust valve because be exported in insufficient mode in emission or In received situation, emission can additionally be drawn at targeted position from shell.This is for example in following situations Under can be advantageous, i.e., for example for make compliant member expand maintenance volume for example due to too small space ratio without The case where all batteries list pond simultaneous faults can be coped with, even if the latter is preferred situation.Emission is uncontrolled in order to prevent Ground removes, and furthermore can be set hose system or another guiding system, the hose system or another guiding system and exhaust valve Or splitter contact, and targetedly and with limiting emission is exported, is for example exported in the ambient enviroment of motor vehicle It goes.
In addition, other volumes may be implemented by the opening for discharging valve, made by the volume by discharging produce Raw pressure is relatively small and makes the temperature generated by emission relatively low, so as to reduce the load of used material Lotus.
Here, again it may be stipulated that: rigid component is arranged at interval with shell outside shell and in normal state, just The component provides support for high force resistance.
In the frame of another design scheme, multiple battery lists pond can be arranged in the module housing surrounded by shell It is interior, and module housing can have the exhaust valve for being specially configured to splitter.In this design scheme, exhaust not only can be with It is carried out, but also can be carried out by the exhaust valve in shell by exhaust collector.It can be special in this design scheme Volume is significantly increased, so as to particularly effectively lower temperature influence and pressure influence.Splitter is as exhaust valve Example can be formed for example by the mandrel (Dorne) integrated or other cutting parts, or can also be by with thinned wall thickness Region formed.Therefore, the opening of exhaust valve can be realized in the interior pressure of such as 4 bars of interior pressure of restriction.Because passing through The flow resistance for the opening being thusly-formed is very small, is filled so shell can soon be discharged object.In addition, by this method The position of the restriction of the emission overflowed from module housing can be reached.
In the frame of another design scheme, shell flexible can have reversibly closed opening.Pass through shell Reversible, can reopening, can be hermetic closed opening, can significantly improve installation and maintenance, because can nothing Get to problem the component of arrangement inside the shell.For example, reversibly closed opening can be realized by fold mechanism, such as roll up Play the shell opened at one end, or for example, by it is known from diving dress, can airtightly closed zipper (Rei Verschluss) Lai Shixian.
