Definitions
- the present invention relates to a heat shield for use in electrical systems and devices which are operated with batteries, nowadays usually lithium-ion batteries.
- the present invention relates to heat shields for electric vehicles.
- Battery-powered vehicles are becoming increasingly popular as an environmentally friendly alternative to conventional vehicles with internal combustion engines.
- One problem is the operational reliability of the cells and cell packs.
- the aim is to keep the battery cells in a temperature range between 15 to 35 ° C, which can be achieved by appropriate cooling or heating, depending on the operating state of the battery system.
- z. B. Overcharging, overheating or short circuit in a cell, it can lead to the so-called "thermal runaway", an uncontrollable heating up to the fire and explosion of the cells. This is a cascading process in which mutually influencing physical and chemical processes build up each other, which leads to a continuous rise in temperature in the cell.
- the components of the electrolyte in particular are converted into the gas phase depending on their boiling point, which leads to an increase in pressure in the cell.
- An electrolyte is composed of different components, with some of these components having relatively low boiling points of only 90.5 ° C (dimethyl carbonate, DMC) or slightly more than 100 ° C (ethyl methyl carbonate, EMC: 107.5 ° C); Methyl butyrate, MB: 102 ° C).
- Safety valves are provided in the battery housings which open when the cell pressure rises in order to be able to discharge the reaction gases form in the battery cells when they overheat. Together with the hot gases, a particle stream of solid decomposition products is carried away at high speed. These solid decomposition products form as a result of the melting of the current collectors, typically made of aluminum, and decomposition of the electrode coatings.
- the pressure relief resulting from the valve opening leads to a sudden release of an easily inflammable gas-particle mixture with a temperature of initially 400 ° C to 700 ° C and a high speed of up to 400 m / sec. out of the cell.
- the particle flow is up to 100 g in the first minute, depending on the cell size.
- the escaping gas usually ignites in the air, so that the temperatures can quickly rise to 800 ° C to 1,400 ° C for approx. 30 to 60 seconds.
- the burned-out cell then slowly cools down.
- a heat protection above the safety valve of the cell or generally above the cells e.g. B. used as a module cover, or directly below, or in conjunction with the battery cover, whose task is primarily to protect the passenger compartment above the battery system from high thermal loads.
- the aim is to keep the temperature that acts on the vehicle floor in the event of a “thermal runaway” as low as possible, ideally below 200 ° C, and to prevent direct flames. It is also necessary to absorb the impact force of the particles as a result of the high impact speed in order to prevent damage, in particular to the passenger compartment.
- a heat shield must therefore be able to fulfill at least three functions in order to be effective:
- this object is achieved by a heat shield which is composed of several layers of different materials which, in combination, can meet the various requirements set out above that are placed on effective blow-out protection.
- the heat shield according to the invention has a first layer made of a heat-resistant elastomer or a fiber composite with an elastomer matrix, which can compensate for the impact force of the particles hitting at high impact speed via elastic deformation and also prevents mechanical damage to the subsequent layers as a result of the impact of the particles.
- This first layer is usually the layer that is closest to the battery cells.
- a second layer made of a material with high temperature resistance, which can withstand temperatures of up to 1400 ° C for approx. 60 Can withstand seconds; a third layer made of an intumescent material which, when exposed to heat, exhibits a swelling or inflating behavior and, as a result of the inflation, forms an insulating layer which acts as a heat brake.
- a heat-spreading layer can be arranged between the second and third layer, which can distribute the heat coming from the second layer over a larger area and thus thermally stress the intumescent layer over a larger area, whereby the intumescent effect can be intensified.
- a carrier layer for the functional layers can be provided as the top layer to increase the stability of the stack.
- the length and width of the layers depends on the dimensions of the battery arrangement, taking into account the trajectory of a gas and particle flow in the event of a gas eruption from the valves.
- the total thickness and thus the thickness of the individual layers of the heat shield composite is essentially determined by the space available. For use in electric vehicles, a total thickness of no more than 1.5 mm is generally desired.
- the mean thickness of the individual layers is 0.3 mm with a variation between 0.2 mm and 0.5 mm.
- the thickness of the individual layers is expediently determined by their function in the stack. For example, the thickness of the heat protection layer is more in the larger range and the thickness of the heat-spreading layer is more in the lower range.
- the layers or individual layers can be sewn to one another, for example to prevent unintentional detachment. So it turned out to be It has been shown to be beneficial to sew the intumescent layer to the layer arranged below and / or above in order to prevent detachment as a result of inflation.
- Heat-resistant threads such as those known from fire protection can be used as sewing material. Examples are aramid threads, such as those sold under the product name Kevlar® or Nomex®.
- a great advantage of the heat shield composite stack according to the invention is its very good 3D deformability. This means that the shield is well deformed and can therefore be adapted to the structural requirements and spatial circumstances of its place of use or intended use.
- Figure 1 shows an arrangement of a heat shield according to the invention above a battery module
- FIG 2 is an exploded view of the heat shield in Figure 1
- FIG. 3 shows a further embodiment of a heat shield according to the invention.
- FIG. 4 shows a diagram with a comparison of the temperature profile on the side of the heat shield facing the battery and the side facing away from the battery over time in the event of a battery failure.
- the impact absorbing layer is the layer of the heat shield composite that is closest to the battery assembly. It is therefore also referred to as the “first” or “bottom” layer of the stack.
- the heat shield 1 is located above the surface of a battery module 2 which has safety valves 3. If the battery ensemble fails, for example as a result of a fire, the hot gas that is formed escapes together with the likewise formed particles of decomposition products through the bursting safety valves 3 in the direction of the heat shield 1.
- the gas and particle flow is indicated in FIG. 1 by a dark line-shaped cloud which rises from the safety valve 3 in the direction of the heat shield 1.
- the heat shield 1 brakes the impact force of the hot gas and particle stream that hits the underside of the heat shield 1 at high speed, and at the same time protects the side facing away from the battery, e.g. B. in vehicles the side with the passenger compartment, before the high temperatures.
- FIG. 2 shows the layer structure of the heat shield 1 shown in FIG. 1.
- the heat shield 1 is made up of several layers of different materials which, in combination, on the one hand compensate for the impact of the hot gas and particle flow and on the other hand dissipate heat so that the side of the heat shield 1 opposite the hot flow is protected from the high temperatures on the impact side of the heat shield 1 is protected.
- the first layer 4 consists of a high-temperature-resistant elastomer with impact-absorbing properties, which by elastic deformation can compensate for the impact of the gas and particle stream hitting at high speed and at the same time can withstand the high thermal loads of up to approx. 400 ° C to 450 ° C. According to the invention, this first layer 4 is therefore also referred to as an “impact-absorbing layer”.
- Suitable elastomers are silicone elastomers e.g. fluorine-vinyl-methyl-silicone rubber (FVMQ), methyl-phenyl-silicone rubber (PMQ), methyl-phenyl-vinyl-silicone rubber (PVMQ), methyl-silicone rubber, methyl-vinyl-silicone rubber (VMQ) , Ethylene propylene diene rubber (EPDM), styrene Butadiene rubber (SBR), acrylonitrile butadiene rubber (NBR), natural rubber (NR), butyl rubber, isobutene-isoprene rubber (IIR), and isoprene rubber (IR).
- FVMQ fluorine-vinyl-methyl-silicone rubber
- PMQ methyl-phenyl-silicone rubber
- PVMQ methyl-phenyl-vinyl-silicone rubber
- VMQ methyl-silicone rubber
- EPDM Ethylene propy
- Mineral fibers can be incorporated into this elastomer layer as a particularly effective embodiment. Suitable examples are basalt fiber or silicate fiber fabrics with weights per unit area of 100 to 600 g / m2.
- the main purpose of the impact-absorbing layer 4 is to intercept the initially very high particle load of the impinging gas and particle stream. This very high load from the particle impact at the beginning generally leads to at least partial erosion of layer 4. However, since the particle load decreases significantly after the first impact, adequate protection of the other layers is ensured by the subsequent heat-absorbing layer 5.
- the subsequent second layer 5 serves as heat protection from the extreme temperatures during the high-temperature phase of the uncontrolled gas outbreak. For effective protection of a passenger compartment, it must be able to withstand the highest thermal loads of temperatures of up to 1400 ° C for approx. 60 seconds. According to the invention, this second layer 5 is therefore also referred to as a “heat protection layer”.
- high-temperature resistant materials are mica materials, basalt fiber composites, oxide ceramic composites, silica fiber composites.
- Heat protection layer 5 at the same time protects the subsequent layers from damage by kelimpakt particles in the event that particles cannot be sufficiently intercepted by the first layer 4.
- a heat-spreading layer 8 is preferably provided between the heat protection layer 5 and the intumescent layer 6.
- the heat-spreading layer 8 serves to distribute the heat over a larger area in order to reduce the thermal load on the heat shield.
- this layer which has a high thermal conductivity, also has the strongest possible anisotropic thermal properties, so that the heat coming from the heat-spreading layer 8 is distributed over a larger area into the subsequent layer 6 with intumescent properties , and the layer 6 with intumescent properties can simultaneously foam over a large area and thus form a continuous insulating layer.
- the heat-spreading layer 8 is as gas-tight as possible in order to support the intumescent effect of the layer 6.
- the gas tightness prevents the inflating gases, which form when the intumescent layer 6 is activated, from being able to escape via the heat-spreading layer 8 and are thus no longer available for the expansion of the layer 6.
- suitable materials with high thermal conductivity and the desired strong anisotropic thermal properties for the formation of the heat-spreading layer 8 are, for. B. graphite foils, carbon fibers, ceramic foils based on hexagonal boron nitride (HBN), graphite foil being particularly preferred.
- HBN hexagonal boron nitride
- the intumescent layer 6 is formed from an intumescent material or contains an intumescent material. When exposed to heat, this layer expands and forms an insulating layer as additional thermal protection.
- the thermal insulating layer It was known to use mineral fleeces, carbon or glass fleeces or felts as the thermal insulating layer, which, however, due to their generally greater layer thickness, increase the overall thickness of the heat shield and thus its space requirements.
- the intumescent materials used according to the invention can be applied in only thin layers which, if necessary, expand when exposed to heat, e.g. B. by releasing non-flammable puffy gases such. B. nitrogen, carbon dioxide or ammonium gases.
- Intumescent materials as they can also be used according to the invention, are generally known from flame protection. Examples are expandable graphite, sheet silicates based on aluminum silicate clay minerals, such as clay minerals from the III group, etc.
- intumescent materials are usually embedded in a polymer matrix, which charred or vitrified under the action of the high temperatures and forms a hard surface as quickly as possible.
- polymer materials for the matrix are acrylic resins, epoxy resins, melamine resins, ethylene vinyl acetate, etc.
- the composites of intumescent material and matrix material can be processed into thin layers, for which common technologies can be used, such as. B. screen printing, doctoring, applying thin foils, etc.
- the intumescent composites made of intumescent material and matrix material can be introduced into a support structure.
- the mechanical rigidity can hereby be improved.
- greater layer thicknesses and consequently a greater expansion effect can be achieved.
- the support structures are open or closed hollow chamber structures.
- Examples are honeycomb structures, where the geometry of the honeycomb can be selected as required, and open-pore, resin-reinforced fleeces and felts, etc.
- An intumescent effect can also be achieved by using resin systems and their thermal decomposition.
- resin systems for this purpose, among other things, Si resins, elastomers, epoxy resins, etc. can be used.
- a combination of heat protection layer 5, gas-tight, heat-spreading layer 8 and intumescent layer 6 has proven to be particularly favorable.
- the gas tightness of the layer 8 prevents the blowing gases from escaping when the layer 6 is activated, the heat protection layer 5 protecting the heat-spreading layer 8 from mechanical damage and impairment of the gas tightness by particles of the gas and particle flow.
- the intumescent layer 6 can be sewn to a layer arranged below and / or above in order to prevent the layer 6 from becoming detached by the expanding gases that are formed.
- the layer 6 can be sewn to the heat-spreading layer 8 and / or a subsequent carrier plate 7.
- the aforementioned aramid fibers can be used as the suture material.
- the upper end of the heat shield composite stack 1 according to the invention is formed by a carrier plate 7 which mechanically supports the further layers.
- the carrier plate 7 can be a glass fiber composite, carbon fiber composite, basalt fiber composite, SMC (sheet molding compound) composite or a mica-based plate. It is also possible to use mechanically resilient plastics with a sufficiently high temperature resistance for the carrier plate 7.
- heat shield composite stack 1 according to the invention can also be sheathed with a thin layer of fiberglass or another material with a corresponding mechanical and thermal load capacity for further mechanical stabilization.
- Fillers can be added to the impact-absorbing elastomer layer 4 as required for a targeted setting of the material properties.
- Fillers can be used with which the heat dissipation within the layer 4 and the temperature resistance can be improved. Examples are graphite, hexagonal boron nitride (HBN), silicon carbide (SIC), aluminum hydroxide (ATH), metal particles, carbon fiber fabrics, C short cut fibers, C milled fibers, etc.
- fillers that support the charring, vitrification, and intumescence of the layer 4 in the high temperature range, such as.
- ATH aluminum hydroxide
- MGH magnesium hydroxide
- Mg (OH) 2 red phosphorus
- oxides such as borax (Na 2 [B 4 0s (0H) 4 ] x 8 H2O), antimony oxide (Sb 2 0s), expandable graphite, Clay minerals from the lllitg group, etc.
- heat-spreading fillers can be provided in the impact-absorbing first layer 4. Heat-spreading fillers support the distribution of the heat of the hot gas and particle flow over the entire surface of the first layer 4 and thus ensure thermal relief, particularly at the point on which the hot gas and particle flow hits first.
- FIG. 3 An example of an embodiment by adding heat-spreading fillers to the layer 4 is shown in FIG. 3, the heat-spreading fillers 9 being shown as a pattern of hexagons which are distributed over the surface. As in the embodiment according to FIG. 2, this is followed by a high temperature-resistant layer 5, a heat-spreading layer 8, an intumescent layer 6 and the carrier plate 7.
- the temperature profile of a heat shield according to the invention was measured and the profile on the side closest to the battery assembly (impact absorbing layer 4) was compared with the profile on the side furthest away from the battery assembly (carrier plate 7).
- the structure of the heat shield composite stack was in the order from bottom layer 4 to top layer 7 as follows:
- Impact-absorbing layer 4 fiber composite made of basalt fiber fabric with a surface weight of 400 g / m2 with an elastomer matrix (Shore A 25/40), thickness 0.3 mm
- heat protection layer 5 fiber composite made of silicate fiber fabric with a basis weight of 300 g / m2 and elastomer matrix, thickness 0 , 3 mm,
- Heat-spreading layer 8 graphite foil, thickness 0.2 mm,
- Intumescent layer 6 thickness 0.4 mm, made of an elastomer material that decomposes at temperatures around 300 ° C,
- Carrier plate 7 thickness 0.3 mm
- Layer 6 and Layer 8 were sewn together with an aramid thread in the X and Y directions in such a way that 50 mm ⁇ 50 mm fields were created.
- the sewing prevents partial detachment of the heat-spreading layer 8 and the carrier layer 7 due to the expansion gases formed.
