Description

The present invention relates to a battery component designed as an underbody battery for a battery device of an at least partially electrically operated vehicle having at least one temperature control device, and to a method for producing such a battery component.The use of high-voltage batteries in electric vehicles or hybrid vehicles usually also requires regulation of the thermal operating conditions. Cooling of the battery cells or battery modules is frequently of particular importance, since the retrieval of the stored energy and also the charging cause a considerable development of heat. Optimum temperature control of the battery is therefore very decisive for reliable and stable operation.Various cooling possibilities of battery cells in a battery have become known in the prior art. Frequently, cooling channels are used for this purpose, in which a cooling medium circulates. For good heat transfer, the cooling channels must run along the battery cells or the components to be cooled. However, this frequently leads to a very high consumption of installation space, which is available only to a very limited extent, particularly in motor vehicles. Therefore, the cooling channels are often only connected to the battery modules at specific regions. However, this has the disadvantage that the usable surface for the heat transfer between the cooling medium and the battery cell to be cooled is greatly limited.DE 10 2009 001 592 A1 discloses a battery device for electrically operated vehicles, in which the battery cells are embedded in an open-pored, porous solid body. A coolant is conducted through the solid body.DE 10 2013 015 208 B3 discloses a battery device for electrically operated vehicles, in which temperature control plates made of a porous material are arranged between the battery cells. A coolant is passed through the temperature control plates.DE 10 2010 013 734 A1 discloses a device for cooling power-electric components by means of an open-pore foam material and, for example, a metal foam, through which a coolant is conducted.DE 102014 101 120 A1 and DE 10 328 047 B3 disclose methods for producing components from metal foams.In contrast, it is the object of the present invention to improve the temperature control and in particular the cooling of battery components of a battery device for an at least partially electrically operated vehicle.This object is achieved by a battery component having the features of claim 1 and a method for production having the features of claim 11. Further advantages and features of the present invention are evident from the general description and the description of the exemplary embodiments.The battery component according to the invention is provided for a battery device, designed as an underbody battery, of an at least partially electrically operated vehicle. The battery component comprises at least one temperature control device. At least one heat carrier fluid for tempering and in particular for cooling at least one battery component can flow through the temperature control device at least partially. The temperature control device comprises at least one at least partially porous body device. The porous body device has a multiplicity of pores through which the heat transfer fluid can flow. The porous body means provides an enlarged surface for heat exchange with the battery component. In this case, the body device is connected to at least one carrier plate in a heat-conducting manner. The battery component to be temperature-controlled is also arranged on the carrier plate. In this case, the body device is arranged between the carrier plate and an underbody plate for the mechanical protection of the battery device.The battery component of the present invention has many advantages. A considerable advantage is that the heat transfer fluid flows through an at least partially porous body device for heat exchange. When flowing through such a porous body, the area involved in heat exchange is extremely large compared with its volume or outer surface. This allows a particularly good heat exchange between the battery component to be temperature-controlled and the heat transfer fluid. The battery component according to the invention can thus be used particularly advantageously if only a small usable surface is available for the heat transfer between the heat transfer fluid and the battery component. This is the case, for example, in high-voltage batteries in electric vehicles or hybrid vehicles, for which often only a very limited installation space can be provided. The battery component according to the invention thus also has the advantage that a considerable amount of installation space can be saved by using it.The body means is preferably provided by a single porous body. Preferably, the body device is formed as a one-piece porous body. This is made of a porous material, for example. However, the body means may be formed of two or more porous bodies. Particularly preferably, the body device is then formed from a multiplicity of individual porous bodies which are significantly smaller than the body device. The body means may be assembled from a plurality of granular and, for example, spherical porous bodies. The individual bodies can be connected to one another. Preferably, a cohesive connection is provided, for example an adhesive connection.The heat transfer fluid is preferably liquid. In this case, the heat transfer fluid is preferably located in a flow system which is closed off from the environment and in particular is fluid-tight. The heat transfer fluid can also be gaseous. It is possible for the heat transfer fluid to be used in a flow system which is at least partially open with respect to the environment. Air can be provided, for example, as gaseous heat transfer fluid.Particularly preferably, the pores are at least partially in flow communication with one another. In particular, the pores are placed in communication with one another such that flow channels are produced in the body device in a multiplicity of branching flow channels. A flow channel preferably provides a closed space, so that the heat transfer fluid can only escape from the body device at specific interfaces. In particular, the body device is open-celled, so that the individual pores are at least partially connected to one another. In particular, each pore has at least one and preferably two and particularly preferably a multiplicity of flow connections to other pores. The flow channels in particular run at least partially non-parallel to one another and / or are arranged non-linearly to one another. Preferably, a labyrinth-like distribution of the flow channels is provided. This produces frequently branching flow channels which are in flow communication with one another to a considerable extent. A particularly large contact surface can thus be provided for the heat exchange.In all configurations, it is preferred that the body device is formed at least partially from a metal material and in particular from a metal foam. In particular, an open-cell or open-cell metal foam is used. Metal foams are particularly advantageous for use in the battery component of the invention. On the one hand, metal foams offer a suitable permeability for the heat transfer fluid. Metal foams also generally have advantageous thermal conductivity. In addition, metal foams having a correspondingly high bending stiffness and a particularly favorable modulus of elasticity are available, so that their use brings, in addition to the thermal advantages, structural advantages, for example for the crash behavior of the battery component. A further advantage of metal foams is that in certain configurations these are also available with a closed outer casing, so that an undesired emergence of the heat transfer fluid on an outer side of the body device can be achieved without greater structural complexity.Other suitable open-cell materials are also possible, which have a corresponding permeability for the heat transfer fluid. It is possible for the body device to be manufactured at least partially from a ceramic foam and / or from a mineral material and / or from a plastic material. Sintered materials are also possible. In particular, the porous body device is designed as a foam body and preferably as a foamed solid body. The body device may also be formed as a honeycomb-like body.It is preferred that the body device is surrounded at least in sections by at least one closed outer casing. The outer casing is suitable and designed to seal the body device with respect to the heat transfer fluid from the environment. This can prevent an undesired escape of the heat transfer fluid from the porous body. In particular, the outer casing is provided with at least one opening at at least one interface. For example, at the interface, a connection to a line system of the temperature control device for the supply and / or removal of the heat carrier fluid takes place.It is preferable that the outer shell is provided by the body device itself. In this case, it is provided in particular that the outer casing is formed from the same material as the porous body. In particular, the outer casing and the body device are formed integrally. Preferably, the pores are closed fluid-tightly on an outer side of the porous body device. The porous body device is suitable and designed in particular for providing a section of an in particular fluid-tight flow connection for the heat transfer fluid. A body device configured in this way can be inserted, for example, directly as a line section into a line system of the temperature control device. It is therefore not necessary to introduce the body device into a tube or a channel, so that time and costs can be saved during production. A body device which provides the fluid-tight outer casing itself can be realized particularly well by a metal foam. During production, the closed outer casing is formed, for example, on a tool geometry delimiting the starting material of the metal foam.It is possible that the body device is configured as a molded part. In particular, the molded part is suitable and designed to be placed at least partially on at least two side surfaces of the battery component to be temperature-controlled and preferably to be placed in a form-fitting manner. Such a shaped part provides a particularly large contact surface for the heat transfer between the battery component and the porous body. By a three-dimensional adaptation to the battery component to be temperature-controlled, such a molded part can be accommodated in an optimum manner even under very limited installation space conditions.Preferably, the molded part can be applied in a form-fitting manner to at least three and in particular to a plurality of side surfaces of the battery component. For a positive bearing, it can also be provided that a gap remains at least in sections between the molded part and the battery component to be temperature-controlled. Further components can be provided there, for example. For example, the molded part is adapted to a battery cell and / or a battery module and / or a housing of these components and can be applied in a form-fitting manner. It is particularly preferred that a fluid-tight outer sleeve is provided by the molded part itself. It can also be provided that the molded part has elevations and / or depressions, which engage in correspondingly oppositely shaped regions of the battery component. It is possible for the molded part to comprise at least one pocket, in which at least one section of the battery components to be cooled is embedded.It is possible for the outer casing to be provided by at least one hollow structural element and in particular by at least one hollow profile. The outer casing can also comprise at least one hollow structural element and / or a hollow profile. In particular, the body device is embedded in a cavity of the component or of the profile. Preferably, the cavity is substantially completely and in particular completely filled by the body device. This allows a particularly good heat transfer. During production, for example, the porous body device or a base body is introduced into such a hollow profile or hollow structural element.It is also possible for a specific recess to be provided in a component, in which the porous body device is accommodated. It is also possible for the porous body device to be accommodated in an at least partially hollow component which can be placed at least partially on at least two side surfaces of the battery component to be temperature-controlled in a form-fitting manner. Such embodiments have the advantage that body devices can be used which themselves do not have a fluid-tight outer casing.It is also possible for the outer casing to be provided by at least two matable components. As matable structural elements, for example, plates and / or carriers and / or profiles and / or other structural elements can be provided. It is possible that the outer casing is provided by at least two different structural elements. It is also possible for the outer casing to be provided by similar components. For example, one part of the outer casing is provided by plates and another part of the outer casing is provided by beams and / or profiles. The matable structural elements can also have recesses and / or elevations which provide the outer casing at least partially. For example, a plate can be provided in which milled-out portions are introduced, into which the porous body device can be accommodated. Such a component can be produced, for example, by filling a divided hollow body with the porous body device and then closing it.According to the invention, the body device is connected to at least one carrier plate in a heat-conducting manner. The battery component to be temperature-controlled is also arranged on the carrier plate. For example, one or more battery cells are connected above the carrier plate in a heat-conducting manner, such that the heat thereof can be discharged through a body device arranged below the carrier plate or a heat transfer fluid flowing therein. It is possible here for the body device to be integrated between two or more carrier plates. According to the invention, the body device is arranged between a carrier plate for the battery components to be temperature-controlled and an underbody plate for the mechanical protection of the battery device. This is particularly advantageous in the case of a battery device which is provided as an underbody battery.In all embodiments, it is preferred that the body device is at least partially formed as a structural-mechanical structural unit for stiffening the battery device. In particular, the structural-mechanical structural unit is suitable and designed to contribute a contribution to the crash behavior and / or a contribution to the overall rigidity of the battery device. The body device is particularly preferably designed as a metal foam, since such metal foams have particularly favorable structural-mechanical properties.According to the invention, the battery component is suitable and designed for use in an underbody battery. Particularly preferably, the porous body device is designed as a structural-mechanical structural unit for stiffening the underbody battery. In particular, such an underbody battery contributes to the overall body rigidity of the host vehicle.The temperature control device is preferably suitable and designed to temperature control and in particular to cool a plurality of battery cells. It is also possible for the battery cells to be heatable by the temperature control device. At least a part of the battery cells can be combined in at least one battery module. For example, a plurality of battery cells are each arranged in groups to form battery modules. The temperature control device is in particular suitable and configured to temperature control and in particular to cool the battery modules. Since a considerable heat development often occurs in battery cells or battery modules, cooling with the battery component according to the invention is particularly advantageous.The method according to the invention is used for producing a battery component for a battery device of an at least partially electrically operated vehicle. The battery component comprises at least one temperature control device through which at least one heat transfer fluid can flow at least partially for the purpose of temperature control of at least one battery component. In this case, at least one at least partially porous body device with a multiplicity of pores through which flow can pass is produced during production. The porous body device is brought into at least one flow connection with the temperature control device, so that the heat carrier fluid can flow through the pores. In this case, the body device is connected to at least one carrier plate in a heat-conducting manner. The battery component to be temperature-controlled is also arranged on the carrier plate. In this case, the body device is arranged between the carrier plate and an underbody plate for the mechanical protection of the battery device.The method according to the invention has the advantage that a battery component can be produced cost-effectively and in an inexpensive manner, which enables a particularly efficient temperature control of battery components. In particular, a porous body device is produced which is configured as described above.The body device is preferably manufactured at least partially from granulate-like basic bodies. Metal foam balls are preferably provided as the base body. In this case, a permeability of the pores for the heat transfer fluid is adjusted by the size of a cross section of the base bodies used. It is also possible that the permeability of the pores is adjusted by a shape of the base bodies. For example, the base bodies are designed in the manner of balls, so that the permeability of the pores can be adjusted by selecting their diameter. For example, base bodies are used which differ in their size and in particular differ by more than 25%, and preferably by more than 50%, or else by a multiple in their size. The permeability of the pores can, however, also be adjusted by the pore size itself and / or by a distance of the pores from one another and / or by the number of flow connections between the pores to one another.The base bodies are preferably connected to one another via an adhesion-promoting layer. For example, the base bodies are coated with at least one adhesive. Another cohesive or also a loose connection is also possible. The base bodies can also be welded to one another at least partially at contact points. In this case, the base bodies can be melted beforehand. As a result, a correspondingly shaped porous body device can be produced particularly easily from the base bodies. For example, the base bodies are placed in a mold for this purpose and connected to one another. The mold can then be removed. In this case, base bodies are preferably used which ensure a closed and in particular fluid-tight outer casing after removal of the mold. However, it is also possible for the base bodies to be introduced into a mold, for example a hollow profile, and to be connected to the latter via at least one activation step. In such a case, the outer shell is provided by the mold.Further advantages and features of the present invention result from the exemplary embodiments which are explained below with reference to the enclosed figure.This shows FIG. 1 shows a highly schematic illustration of a battery device having a battery component according to the invention in a motor vehicle; FIG. 2 shows a highly schematic illustration of a battery device with a battery component in a sectional side view; FIG. 3 shows a further embodiment of a battery component; and FIG. 4 shows another embodiment of a battery component.FIG. 1 shows an at least partially electrically operated vehicle 100, for example an electric vehicle or a hybrid vehicle, having a battery component 1 according to the invention. The battery component 1 comprises a temperature control device 3 for controlling the temperature of a battery device 2, which supplies an electric traction drive 102 of the vehicle 100 with energy. The battery device 2 is arranged here in an underbody region of the vehicle 100 and is designed as an underbody battery 22.The battery device 2 comprises a plurality of battery cells, of which only some are shown by way of example for the sake of better clarity. The battery cells can be organized in groups into battery modules 32, of which only one battery module 32 is shown for the sake of better clarity. The battery device 2 additionally has power electronics 101. The battery device 2 can also comprise further components 12, such as a control device and / or a charger.In order to be able to operate the battery device 2 under optimum temperature conditions, certain battery components 12 are cooled and / or heated by the temperature control device 3. The temperature control device 3 preferably serves for cooling the battery cells during the driving operation. Cooling of the battery cells during charging processes or other operating states can also be provided. The temperature control device 3 can also be provided to heat certain battery components 12, for example in order to bring them to a desired operating temperature in a cold environment.The temperature control device 3 comprises a line system 13 through which a liquid heat transfer fluid can flow. A gaseous heat transfer fluid can also be provided. For cooling, heat is extracted from the respective battery components 12 and transferred to the heat transfer fluid. The line system 13 runs along the battery components 12 to be temperature-controlled. In the battery device 2 shown here, for example, a cooling duct runs below the battery cells to be cooled or the battery module 32.A pump device can be provided for conveying the heat transfer fluid. Passive delivery of the heat transfer fluid can also be provided. For cooling the heated heat transfer fluid, the temperature control device 3 can also comprise a heat exchanger. The heat exchanger is provided, for example, as a cooler with a surface through which air flows. To adapt the temperature of the heat transfer fluid, at least one thermostat and / or at least one controllable valve or further devices provided for regulating coolant temperatures can be included.A particular advantage of the battery component 1 according to the invention is that the heat transfer fluid flows through one or more porous body devices 5. The porous body means 5 comprises a plurality of pores which are in flow communication with each other. This results in flow channels that branch off many times within the body device 5.Porous body devices 5 are therefore preferably arranged in the line system 13 wherever the line system 13 runs along components 12 to be cooled. For example, a plurality of body devices 5 through which flow passes can be arranged below the battery components 12 to be temperature-controlled. However, it is also possible for large-area body devices 5 to be arranged below a plurality of battery components 12 to be temperature-controlled.The porous body device 5 is here exemplarily formed as a metal foam 25. Such metal foams 25 offer a very advantageous thermal conductivity and additionally have advantageous structural properties, so that the porous body device 5 preferably also contributes to the stability of the battery device 2.In order to prevent the heat transfer fluid from escaping from the porous body device 5, the latter is embedded here in a hollow structural element and, for example, in a hollow profile 351. The hollow profile 351 and the embedded body device 5 are fluidically connected to the remaining line system 13. However, it is also possible and preferred for the body device 5 and, for example, a metal foam 25 to have a closed outer casing 35 so that these can be directly integrated as a line section in the line system 13.FIG. 2 shows a highly schematic detail of a battery device 2 having a battery component 1. For fastening the battery components 12, the battery device 2 here has a receiving structure which comprises a carrier plate 352. The battery cells are arranged on the carrier plate 352. The carrier plate 352 is preferably formed from a metal material and, for example, as an aluminum plate. Such a metal plate enables a particularly good heat transfer and also offers a large-area heat exchange. In addition, the carrier plate 352 enables a reliable and secure separation of the battery cells from the heat transfer fluid.A section of the line system 13 of the temperature control device 3 extends below the carrier plate 352. Thus, the heat of the battery cells can be transferred particularly well to the body device 5 via the carrier plate 352 and can be dissipated with the heat transfer fluid.The porous body device 5 has a very large number of pores 15 here, which have been shown in a greatly enlarged and schematic manner for improved clarity. Therefore, the actual size relationships are not reproduced here. The porous body device 5 is open-pored, so that the pores 15 are in flow communication with one another. This results in a widespread network of flow channels for the coolant which are in themselves multiply branched.The porous body device 5 has an outer casing 35 which prevents the heat transfer fluid from exiting the line system 13. The outer casing 35 is provided here by a plurality of components 352, 353. A delimitation relative to the battery cells takes place via the carrier plate 352. The delimitation from an underside of the battery device takes place via an underbody plate 353. The lateral boundaries of the outer casing 35 are not shown in the sectional illustration shown here and are provided by further structural components, for example by beams or profiles.The underbody panel 353 preferably serves as a protection from impacts emanating from the floor side of the vehicle 100. The underbody plate 353 preferably also forms an insulation layer that minimizes undesired thermal exchange of the heat transfer fluid with the environment (external heat, for example, in summer or cold in winter). The underbody plate 353 may form, for example, an air-filled or gas-filled chamber or a vacuum chamber, whereby heat conduction from the porous cooling device into or out of the environment may be minimized. In one configuration, the plate 353 may be formed of a layered structure of various insulators. For example, fiber composites can be used as insulators, such as polyethylene fibers, polyester fibers and in particular polyamide fibers and / or aramid fibers. Glass fibers and / or ceramic fibers can also be used. Fiber materials with a correspondingly high toughness are preferably selected. Thus, an impact-stopping effect can additionally be achieved (as in ballistic vests or armors, for example). As insulators and / or reinforcements or armouring, it is also possible to use thermoplastic matrices in combination with suitable and preferably with the aforementioned fibrous materials. An underbody plate 353 configured in this way meets the requirements mentioned above particularly well.Alternatively to a separate outer casing 35 provided, for example, by structural elements 352, 353, the outer casing 35 can also be provided by the body device 5 itself. For this purpose, for example, a metal foam 25 can be used which has closed pores on the outer sides. In this case, an underbody plate 353 can additionally be used, for example for insulation and / or as protection against mechanical influences. In addition to the outer casing 35 of the body device 5 which is provided itself, further structural elements 352, 353 can also be provided. A connection to the line system 13 of the temperature control device 3 is then effected, for example, by selective openings in the body 5.The porous body device 5 is also designed here as a structural-mechanical structural unit 55, which is provided for stiffening the battery device 2. The porous body device 5 is particularly preferably designed as a metal foam 20 since metal foams have a particularly high bending stiffness and a correspondingly high modulus of elasticity. As a result, the porous body device 5 contributes to the protection of the battery components 12 and in particular of the battery cells in the event of a crash. The battery component 1 according to the invention therefore also offers structural-mechanical advantages over hollow pipelines.FIG. 3 shows a detail of a battery device 2 having a battery component 1, in which the porous body device 5 is configured as a molded part 45. The shaped part 45 is here adapted to the shape of the battery cell to be cooled. The molded part 45 can also be adapted to the outer contours of other battery components 12 and, for example, of a battery module 32. As a result of the positively locking contact on the battery cell, a particularly good heat transfer to the porous body and thus to the heat transfer fluid is achieved.In the embodiment shown here, the molded part 45 surrounds the battery cell on a plurality of side surfaces 121- 123. The shaped part 45 engages around the battery cell in a U-shaped manner, so that it bears in a positive-locking manner against the underside 121 and against the two side surfaces 122, 123 adjoining the underside 121. Embodiments can be provided in which the molded part 45 also covers the transverse sides and / or the upper side at least partially. A covering over the entire surface of certain or all side surfaces 121- 123 can also be provided.The shaped part 45 shown here has an outer casing 35 which consists of the same material as the shaped part 45 itself and which is formed integrally therewith. For example, the molded part 45 is made for this purpose from a metal foam 25 with a closed covering layer. As a result, the outer casing 35 is provided by the molded part 45 or the body device 5 itself. It is thus possible to dispense with embedding in a separate outer casing 45, which significantly reduces the production outlay, particularly in the case of complex shaped parts 45. However, it is also possible for the molded part 45 to be embedded in a separate outer sleeve 35, for example in a hollow profile.FIG. 4 shows a porous body device 5 of a battery component 1, which is assembled from base bodies 65, 75. The base bodies 65, 75 have an adhesion-promoting layer 650 on their outer side. The base bodies 65, 75 are here considerably smaller than illustrated and have dimensions in the micrometer range or millimeter range, for example. Thus, by joining the base bodies 65, 75, body devices 5 of correspondingly complex configuration can be produced.In this case, base bodies 65, 75 can be used which have different cross sections or different diameters. Thus, the permeability of the body device 5 can be adjusted by a specific selection with respect to the size or the cross section of the base bodies 65, 75. In the example shown here, the body device 5 is manufactured from granulate-like and substantially spherical base bodies 65, wherein base bodies with a larger diameter 65 and with a smaller diameter 75 were used.The battery components presented here were preferably produced by the method according to the invention. In this case, the porous body devices 5 are first manufactured and subsequently placed in flow connection with the line system 13 of the temperature control device 3. The permeability of the pores 15 for the heat transfer fluid is adjusted via the base bodies 65, 75 used. As shown in FIG. 4, ball-like base bodies 65, 75 with different diameters can be used for this purpose.The outer casing 35 can be produced by various method steps. For example, the body device 5 can be inserted into a component 351- 353 which provides the outer casing 35. For this purpose, the body device 5 is inserted into a hollow profile 351, for example. It is also possible for the body device 5 to be introduced into a divided hollow body which is then closed. The body device 5 can also be inserted between two or more structural elements 352, 353, which are subsequently connected to form a closed outer casing 35.However, the outer shell 35 may also be provided by the porous body device 5 itself. For this purpose, for example, during the production of a metal foam 25, the outer shell 35 can be produced on the tool geometry (shell shape) delimiting the foam body. This method step is particularly advantageous in the configuration of complex shaped parts 45.In an advantageous embodiment of the method, the body device 5 is assembled from a plurality of granulate-like base bodies 65, 75 and in particular metal foam balls. The base bodies 65, 75 are coated in particular with an adhesion promoting layer 650 and, for example, an adhesive. It is also possible for the base bodies 65, 75 and preferably metal foam balls to be at least partially melted by targeted heat supply, so that these are welded to one another at their contact points. These base bodies 65, 75 are then introduced, for example, into hollow profiles 351 or other suitable structural elements 351-353. Via a suitable activation step, the base bodies 65, 75 are then connected to the components 351- 353 providing the outer casing 35. The base bodies 65, 75 can also be introduced into correspondingly complexly shaped components 351-353, so that desired shaped parts 45 can be produced.
