Summary of the invention
Theme of the present invention is battery system, described battery system has the battery module with multiple battery list pond, described battery list pond has at least one respectively and is arranged in single pool unit in the housing of single pond, wherein single pond housing has the exhaust valve for being exhausted the emission (Entgasungsemission) particularly formed in the housing of single pond in case of a fault respectively, and the exhaust collector be wherein provided with for emission is derived from battery system, this exhaust collector has the opening be connected with exhaust valve, it is characterized in that, exhaust collector can be out of shape because of emission, make the volume that surrounds by described exhaust collector can increase.
This type of battery system allows to be exhausted with improvement, and with regard to the manufacturability of cheapness and space-saving especially installation, this realizes by allowing reliable exhaust of emission and deriving.
For this reason, first battery system comprises the battery module with multiple battery list pond, and described battery list pond has at least one respectively and is arranged in single pool unit in housing.Therefore battery module comprises multiple battery list pond or is built by multiple battery list pond, and described battery list pond in a way known can be connected in series or in parallel.Battery list pond has single pond housing respectively at this, in the housing of described single pond, arrange one or more single pool unit.At this, a single pool unit is set and comprises multiple single pool unit is set equally in housing in the intelligible mode of those skilled in the art.Single pool unit can construct lithium ion list pond as is known in conventional example substantially, and is such as configured to the element of winding (Wicklungselement).
In order in case of a fault can by formed in unit inside, derive from battery list pond as the gas described in detail in the preceding article, single pond housing or the multiple single pond housing be arranged in module have the exhaust valve being such as constructed to substantially known breakable.At this, hereinafter by escaping gas or at least partly for the mixture of gaseous state is called emission together with the pressure of its part and characteristic thereof, the temperature namely particularly improved and raising.
For following situation, namely, exist in one or more battery list pond and relate to the failure condition that emission overflows from battery list pond, emission not only should be derived from battery list pond, but also should limit from battery system and in an advantageous manner from the equipment derivation being equipped with battery system.Such as, emission can be guided out from electro-motor or by electrically driven vehicles.For this reason, the exhaust collector being used for emission to derive from battery system is set in aforementioned battery system.Therefore, this kind of exhaust collector can such as construct or be arranged as pipeline or passage or pipe-line system or channel system especially, with by emission on purpose and derive with limiting and guide to the exhaust position limited from battery system.Such as, exhaust collector to may be used for pernicious gas not to be directed in vehicle passenger cabin but is directed in vehicle-periphery.At this, exhaust collector can such as being directed away emission from battery system.In order to emission is directed in exhaust passage from battery list pond, described exhaust passage can have the opening of suitable quantity according to the quantity of single pond housing or exhaust valve, exhaust valve or single pond housing in described opening and battery list pond are connected to wiper seal in an advantageous manner.Therefore opening is orientated as and emission can be flow in exhaust collector by exhaust valve and opening.If pressure-tight connection exists, can also mean that emission flow into the risk not having uncontrolled spilling in exhaust collector.
With regard to aforementioned battery system, in this regulation: exhaust collector can be out of shape because of emission, such as deployable or extending, make the volume that surrounds by described exhaust collector can to increase or inflatable.This type of design relative to solution well known in the prior art, namely arrange special rigidity or the solution of unmodifiable exhaust collector in its volume, there is significant advantage especially.
By arranging the exhaust collector constructed as previously mentioned, this exhaust collector can be out of shape or extend when emission overflows from one or more battery list pond or launch, thus the emission all occurred can be derived by exhaust collector without problems.
Can realize thus: exhaust collector can be arranged in compactly on the housing of single pond under the operating state of the hope of battery system, and only forms required volume in case of need.Thus, special conserve space can be realized exhaust collector is arranged, wherein however still can realize large cross section without problems, and for good and all need not maintain enough structure spaces, or spatially require that high gatherer does not cause installation difficulty.The large cross section of exhaust collector can be favourable at this, dynamically can derive the emission be under pressure.
At this, can by the distortion of exhaust collector and concomitantly by by exhaust collector the increase of volume of surrounding produce the cross section increased relative to the layout of rigidity even without problems, because the cross section of described increase does not need for good and all to exist as previously mentioned.Thus, compared with when less cross section, because desirable gas law can make pressure relatively less and temperature is relatively lower, thus the load occurred especially as temperature and pressure for lower described material.
By saving the gatherer of rigidity and therefore can also realizing other advantages by reducing rigid element, namely, the generation of following situation can be prevented: because the size of this type of rigid element and quality, in dynamic vehicle operating, in unrestricted Mobile solution such as in electrically driven vehicles, the displacement of parts can cause sealing system to have top load in interface.
In addition can only be made up of flexible material by exhaust collector, the battery list pond of reality or its housing are then by hard and such as formed by the housing of rigidity, and this can not affect the fail safe in actual single pond negatively.Because also effectively can be prevented the mechanical failure in single pond in addition by stable single pond housing.
At this, being particularly suitable for as the material of exhaust collector is resistant to elevated temperatures polymer, namely stable with regard to emission polymer, such as polyethylene terephthalate or stainless steel, such as SUS304, described material such as can have fold, and described fold launches with can being similar to bellows (Blasebalg).This type of material can by high flexibility and high stability and particularly light weight be integrated in one.
In a word, therefore aforementioned battery system can realize cheapness, space-saving, light weight and reliably, for being vented when breaking down in battery list pond gas extraction system.
In a kind of framework of design, exhaust collector can have at least one such region, and this region has the shape that inwardly arches upward and this region can be converted into the region with the shape outwards arched upward by emission.In this design, therefore the one or more regions in multiple region are inwardly in or the shape protruded in the operation of the hope of battery system.By emission, especially by the pressure of emission, corresponding region or multiple corresponding region can be realized at this and be outwards out of shape and be therefore in the shape of depression.Can realize especially Absorbing hydraulic pulsation without problems thus, because the distortion in the region correspondingly formed by distortion or at least one of exhaust collector, the spilling energy of emission is absorbed or is applied in for distortion or consumes for distortion.At this, such as but without limitation on each battery list pond or respectively adjacent with the exhaust valve of single pond housing battery list pond can exist respectively the region of protrusion.But, especially, exhaust collector also can be made in this construction in principle to be formed by metal as described above at this.Metal such as can be configured to metallic plate, to realize the deformability of wishing.
In this design, therefore can Absorbing hydraulic pulsation especially effectively.Thus, following shortcoming can be evaded, that is, only dynamically be absorbed conditionally until the compression shock caused due to battery list pond continuous exhaust pneumatic wallop of 10 bar by the stiff case surrounded according to prior art.Therefore can avoid: there will be the distortion of housing parts because very dynamic pressure is set up when being vented in battery list pond, the seal between housing parts can not compensate or only difficulty can compensate the distortion of described housing parts.Therefore, problems not bery appears in the exhaust collector of foregoing soft and particularly not bery occurs in this configuration but also not bery appear in principle according in exhaust collector of the present invention.
In another design, exhaust collector can at least in part by can be out of shape because of emission and/or fusing material surround.At this, described material can directly by be placed on exhaust collector or spaced apart with this exhaust collector.In addition, corresponding material fully can surround exhaust collector or only partly be adjacent to exhaust collector arrange.This material can be out of shape due to emission at this, is compressed especially or melt by emission.Distortion can be occurred by the pressure of emission especially at this, and fusing by the temperature of emission and concomitantly can be occurred by the temperature of exhaust collector especially.Thus, exhaust collector can be realized and occupy space previously occupied by described material when being vented.Thus, can complete layout stable especially under extra high compactedness, the volume that described layout does not affect exhaust collector negatively increases.
Such as, previous materials can be expanded material and deformability or compressible thus.In this design, such as, can use the foamed plastics (Schaumstoffe) be such as made up of polyurethane material.
In fusible voltinism, the fusing point of this type of material can be in or lower than the temperature of emission, thus not only can realize the compression of material but also can realize the fusing of material.Thus, the expansion of exhaust collector can also be further improved.The material with corresponding fusing point also can be aforementioned polyurethane material or polyurethane foam or other foamed plastics.
This class A foam A or foamed plastics can also provide other advantages, and namely described foam or foamed plastics form insulation effect, particularly thermal insulation effect, thus can save other insulating material in this position, or obviously can reduce the use of described insulating material.Therefore, especially in this design, the use of battery system can be especially favourable in following application, and namely the application of described battery system or should be configured to double-deck and have coldplate to insulate by thermal insulation.
Can arrange protection component in the framework of another design, described protection component is located in the front being arranged in the seal between exhaust collector and single pond housing at least partly when being vented.At this, seal can directly be arranged between single pond housing and exhaust collector, or indirectly and be arranged between another housing parts and exhaust collector or single pond housing at this, wherein, another housing parts described is arranged between exhaust collector and single pond housing.But seal is spatially arranged between single pond housing and exhaust collector in principle.
This type of protection component can improve the sealing structure and stability that are made up of housing parts such as single pond housing or module housing further.In this design, therefore can react in particular for following problem, namely because the combination of the compression shock between exhaust cycle, temperature and chemicals makes single pond housing such as very difficult with the sealing of exhaust collector.In addition, the seal between single pond and gatherer often comprises rubber or another plastics, and is subject to top load when being vented and can becoming blow-by potentially thus.In order to anti-problem here, in this design, be provided with protection component.
Protection component can be such as metal and/or be configured to membranaceous, and inserts except seal or be fixed between battery list pond and exhaust collector.Such as, protection component can be fixed between single Chi Gai and module lid.Protection component so constructs at this, makes it can upwards place when the exhaust of single pond or open, and therefore outside by be placed on exhaust pathway and can to protect and additionally sealing is in the parts, particularly seal at its place.Therefore, seal can be protected by the infringement of temperature and chemicals by protection component, and in the space that can prevent chaff interference from flowing between single Chi Gai and seal in addition and gatherer interior and seal is degenerated.In principle, being arranged on this and can using as common rubber seal of this type of protection component, and the region such as between bridge joint list Chi Gai and gatherer.
In the framework of another design, exhaust collector can be fastened on housing parts by bonding connection or by the kayser connected also referred to as clamping.Especially, this type of connection can be formed and seal and lasting connection reliably in the combination of the housing parts of rigidity with flexible housing parts.At this, aforementioned connection type can be produced at an easy rate and manufacture simply.
Being connected to hermetically by exhaust collector as attainable in previous designs scheme on housing parts, being such as connected to hermetically on module housing or single pond housing is the particularly advantageous precondition of battery system reliability service.Especially, because discharge line (Ableitungen) does not jeopardously run battery system with the health that can realize for Vehicular occupant when being such as used in vehicle that is connected to that the pernicious gas of corresponding battery component seals.Therefore, can ensure especially: when being vented, poisonous pernicious gas not to enter in passenger compartment but is exported to environment.
In the framework of another design, battery list pond and exhaust collector can at least partly surround by the shell of flexibility.At this, can specify: the parts of battery system are surrounded by this type of shell in single pond aspect, module aspect or group aspect, wherein can compensate pressure oscillation by pressure-tight particularly flexible connection accordingly.The combination of different materials being such as constructed to the shell of film can be implemented in the different physical features on face at this, such as different thermal conductivity.
" flexible shell " also can be understood as so a kind of shell, and this shell such as such as can extend or launch because emission flow in shell and therefore its volume surrounded can increase.In this design, the destruction of the pernicious gas can overflowed from battery list pond when special reliably protection surrounding environment exempts from exhaust can be realized.Specifically, in this design, the seal of the subassembly of the seal of the subassembly of battery system, particularly battery module or whole battery system can be realized by the shell with flexible material with the such as flexible form of flexibility, reduces the ductility of described subassembly time in narrow structure space battery being installed to such as vehicle.Therefore, the compression shock during exhaust of battery list pond dynamically can be absorbed by the housing of the flexibility of surrounding, and particularly for following situation, that is, exists between battery list pond and exhaust collector or creates undesirable blow-by.
The advantage of the shell of this type of flexibility can be: described shell only must have its maximum dilatation under exhaust condition, and when mounted by emptying module housing or the housing grid (Geh usegitter) that can reduce the reality that shell described in its dilation only can need wrap up and seal slightly larger than it significantly.Thus, can obtain battery system or its subassembly, described subassembly has minimum possible volume expansions degree and therefore can easily and at an easy rate be arranged in spatially limited structure space, in such as motor vehicle.So under exhaust situation, such as motor vehicle or next-door neighbour's motor vehicle, usually because technical reason not spendable structure space in normal operation can be used as gas held portion or for guiding system.
Such as, flexible shell and exhaust collector can by same thickness and/or the flexible material with identical thermal coefficient of expansion and mechanical swelling coefficient form, such as shell can be formed by identical material structure with exhaust collector.Flexible shell can be made up of resistant to elevated temperatures polymer, namely by polymer, such as polyethylene terephthalate stable with regard to emission at this.Alternatively, shell can be made up of with reference to the stainless steel described by exhaust collector such as middle above, and such as has fold, and described fold launches with can being similar to bellows.The connection of material or sealing can such as by bonding, welding or sulfuration realizations.Once the internal housing structure of rigidity that has especially of such as module housing be surrounded with the shell of exhaust passage or exhaust collector, then the part mechanical formula of flexibility can be pressed onto easily particularly on latticed inner shell and by emptying for the shell of flexibility.Describedly emptyingly can to complete in the manufacture of battery system.
Pass through the negative pressure of formed such as 0.8ba, the exhaust collector such as with exhaust hose can be forced on all exhaust ports of single pond housing, such as own to connection sealing to vehicle-periphery ground to surrounding environment thus.Flexible parts are retracted to together by the internal structure of rigidity size given in advance, and also after negative pressure connecting portion is sealed and keep these sizes after removing negative pressure pump.In this way, battery system or its subassembly can obtain minimum possible size.
Time under accident conditions from the exhaust of one or more battery list pond, formed until first the compression shock of 10ba is pressed onto by exhaust valve on the opening in exhaust collector.Exhaust collector with exhaust passage is connected with flexible Shell at this.This means that battery pack or battery module and exhaust apparatus are surrounded by the shell of the such as bag configuration of flexibility sealed, guided the exhaust passage of exhaust collector or multiple exhaust passage by described shell.Such as, only exhaust collector can have opening that lead to surrounding environment, that such as lead to the hope of the surrounding environment of motor vehicle.
This obvious advantage had is that the opening in exhaust collector does not need to be connected airtightly with single pond housing, or when such as there is blow-by between exhaust collector and single pond housing, also reliable derivation or the reception of emission can be realized, because there is not another exhaust pathway for emission.
Flexible shell and exhaust collector can expand to the max architecture that defined by such as vehicle structure spatially flexibly.Therefore, the pernicious gas for sending from battery list pond or multiple battery list pond provides the larger expansion space of the conventional exhaust gas system of specific rigidity version.By larger expansion possibility, the pressure and temperature of admixture of gas becomes not too high, and therefore flexible material can tolerate occurred load usually without problems.Therefore, can make full use of in this design " inoperative (totes) volume ", i.e. substantially unemployed volume in the surrounding environment of battery system, and obtain the volume being used for emission.
At this, the stability increased can also realize in the following manner: in the surrounding environment of battery system, arrange such equipment, and the exhaust collector under state that is that under being in swelling state, be namely such as in expansion or that extend and/or soft shell can by being put on described equipment.Described equipment this can be preferably rigidity and when battery system is such as arranged in luggage compartment or when neighboringly arranging with this luggage compartment, described equipment such as can be made up of vehicle part, such as, be made up of the inwall of vehicle luggage compartment.Thus, can reliably receive and protect the parts of the flexibility such as can launched or extend by packaging structure (Verpackungsarchitektur) due to emission, the overvoltage tolerance of increase can be obtained thus.
At this, can also specify: connector that exist if desired, that guided by the shell of flexibility utilizes seal, the sealing ring that such as bonds seals, thus however still can produce air-tightness.If such as cables etc. are surrounded by described connector, such as cable is surrounded by the terminal in module or each battery list pond, then described cable can arrange in the enclosure especially or also can completely wound form ground or be set up with the structure of helical wire form, thus be vented time described cable self also can extend or increase its space length together with soft shell.
In the framework of another design, on shell, such as, on the surface in the sensing housing interior volume of shell, be provided with a kind of material, this material has larger thermal conductivity compared to the material of shell.Such as, when use has the adhesive of thermal conductive resin, this material can bond with shell or weld.Thus, particularly preferred hot link can be utilized to realize battery list pond to be arranged in arrange on the cooling plate on cooling device, such as, and wherein cooling device can be arranged in outside shell.Thus, can prevent cooling device from being soaked by dew in the enclosure and therefore adversely affecting battery list pond.In addition, the operation of battery system or module can be simplified.In addition, in this design, structure type ground compensate for height tolerance can be depended on especially, and the hot link on cooling device can be improved.
In the framework of another design, flexible shell can have exhaust valve, and described exhaust valve is opened in the predetermined interior pressure of shell.Such as, this type of exhaust valve can be constructed to splitter (Sollbruchstelle).Further fail safe income can be realized by this type of exhaust valve, because when emission is exported in insufficient mode or receives, emission additionally can be drawn from shell in position targetedly.This can be such as favourable in a case where, and the volume being namely such as provided for the maintenance that compliant member expands such as can not tackle the situation of all batteries list pond simultaneous faults, even if the latter is preferred situation due to too small space ratio.Controllably do not removed to prevent emission, hose system or another guiding system can be set in addition, this hose system or another guiding system contact with exhaust valve or splitter, and targetedly and limit that emission is derived by ground, go in the surrounding environment that such as exports to motor vehicle.
In addition, other volumes can be realized by discharging the opening of valve, making the pressure that produced by emission relatively little by described volume and making the temperature that produced by emission relatively low, thus the load of used material can be reduced.
At this, can specify again: outer and arrange the parts of rigidity at interval with shell in normal state at shell, with regard to high force resistance, described parts provide support.
In the framework of another design, multiple battery list pond can be arranged in the module housing that surrounded by shell, and module housing can have the exhaust valve being configured to splitter especially.In this design, exhaust not only can be undertaken by exhaust collector, but also can be undertaken by the exhaust valve in shell.Volume can be increased especially significantly in this design, thus especially effectively can lower temperature impact and pressure influence.Splitter can such as be formed by the axle integrated (Dorne) or other cutting parts as the example of exhaust valve, or also can be formed by the region with thinning wall thickness.Therefore, opening of exhaust valve can depress pressure realization in such as 4 bar in restriction.Because very little by the flow resistance of the opening so formed, filled so shell can be discharged thing soon.In addition, the position of the restriction of the emission overflowed from module housing can be arrived in this way.
In the framework of another design, flexible shell can have the opening reversibly closed.By reversible, that can reopen, the opening that can be hermetic closed of shell, can improve significantly and install and safeguard, because layout parts in the enclosure can be got at without problems.Such as, the opening reversibly closed can be realized by fold mechanism, the shell at one end opened as rolled, or by such as from diving dress slide fastener (Rei verschluss) that is known, that can close airtightly realize.
