Description

TECHNICAL FIELD

[0001] The application relates to a battery for a motor vehicle. BACKGROUND

[0002] If a battery is used as an electrical energy accumulator in a motor vehicle designed as an electric vehicle or a hybrid vehicle, a large number of battery cells of the battery are usually connected to one another in an electrically conductive manner. Here, a plurality of stacks of battery cells can also be arranged adjacent to one another or next to one another in the stacking direction of the battery cells.

[0003] For example, DE 10 2012 219 782 A1 describes an assembly of a plurality of stacks of battery cells, wherein the stacks are adjacent to one another in the stacking direction of the battery cells. The battery cells of the respective stacks are here accommodated in a box-shaped housing in which the battery cells are loaded with a pressure. The respective housing comprises two end walls which are opposite one another in the stacking direction and two side walls which are screwed or welded to the end walls. A frame is thus provided by the housing which presses or compresses the battery cells of the respective stacks with a prestressing force.

[0004] Furthermore, it can be provided in a battery for a motor vehicle that a respective battery module with a plurality of prismatic battery cells is provided. Here, the battery module can have a module frame which has two end plates which are opposite one another in the stacking direction of the battery cells and tie rods which connect the end plates to one another. The end plates thus act as pressure plates which load the battery cells with a pressure in the stacking direction or press the battery cells against one another in the stacking direction. Such a module frame can be formed from a metal component, wherein as a metal, in particular, aluminum and / or steel can be used.

[0005] Arranging a large number of battery cells in a module frame means that, compared to the case in which the battery is designed with more battery modules which each have fewer battery cells, fewer such end plates or pressure plates and fewer tie rods need to be used. In correspondence therewith, when using battery modules with a large number of battery cells, more available installation space can be used for or occupied by the battery cells. This is advantageous for the amount of electrical energy which can be provided by the battery.

[0006] It can be provided, in particular in the case of relatively large battery modules, that a pressure plate, i.e. a plate-like element, is arranged between two stacks of battery cells, which, like the battery cells clamped in the module frame, is loaded with a pressure. Such a pressure plate can be used to secure or arrange further components of the battery on the battery module.

[0007] It can be provided that the pressure plate is configured as a profiled part composed of aluminum, which is manufactured by extrusion. This makes it possible for the tie rods of the module frame to be connected with the pressure plate, for example by welding. However, it has proven to be comparatively complex to introduce a thread into such a pressure plate composed of aluminum. Because for this purpose a subsequent machining of the pressure plate is necessary.

[0008] Furthermore, the configuration of the pressure plate from an electrically conductive metal, such as aluminum, means that an insulating element composed of plastic has to be provided, if possible, in order to ensure a sufficiently large air distance or creepage distance. The provision of such an insulating element composed of plastic is also associated with a corresponding expenditure in the manufacture of the battery.

[0009] Furthermore, the material used, which is aluminum in form, as well as the machining of the pressure plate and additionally the provision of the insulating element make the pressure plate arranged between two stacks of battery cells an expensive component of the battery. SUMMARY

[0010] It is the task of the present invention to give a battery of the type mentioned at the outset which can be produced particularly easily.

[0011] To this end, the present invention proposes a battery for a motor vehicle. The battery for a motor vehicle according to the invention comprises a first stack of battery cells. In the first stack, the battery cells are loaded in a stacking direction of the battery cells. The battery comprises a second stack of battery cells, which is arranged adjacent to the first stack in the stacking direction. The battery cells of the second stack are also loaded in the stacking direction. A pressure plate is arranged in an intermediate space configured between the first stack and the second stack, which is loaded in the stacking direction. The pressure plate is composed of plastic at least in a respective abutment region, in which the pressure plate is in contact with the first stack and the second stack. At least one base body of the pressure plate having an abutment region is composed of plastic, and at least one insert composed of metal is introduced into the base body, on the surface of which at least one metal component of the battery for electrical contacting and / or electrical connection can be fixed by welding. Thus, the pressure plate can be provided particularly easily and with little expenditure. This favors an easy manufacture of the battery. Furthermore, plastic as a material is advantageous, for example, compared to aluminum.

[0012] Furthermore, the pressure plate composed at least partially of plastic can be produced particularly quickly, which is a plate-like or square component of the battery different from the battery cells. This also favors a particularly easy manufacture of the battery.

[0013] Furthermore, attachment sites for the accommodation of further components of the battery on the pressure plate can be provided or integrated into the pressure plate particularly easily, quickly and with little expenditure, since the pressure plate is manufactured at least partially from plastic. This can occur directly or be realized in the manufacture of the pressure plate.

[0014] Preferably, the pressure plate has at least one passage opening for guiding at least one coolant line of a cooling device of the battery through the pressure plate. In other words, in this design the at least one coolant line can be guided through the at least one passage opening configured in the pressure plate. Due to the provision of the at least one passage opening in the pressure plate, the coolant line guided through this passage opening is well protected.

[0015] Thus, for example when a motor vehicle equipped with a battery hits an obstacle, the coolant line is not in the load path of the load acting on the battery. It is thereby possible to ensure in particular a high degree that the at least one coolant line is not damaged when the battery is loaded with force, for example as a result of an accident, and that therefore no coolant escapes from the coolant line. This protection of the at least one coolant line by the pressure plate is particularly advantageous in the case where the pressure plate is arranged substantially centrally in the battery comprising two stacked battery modules.

[0016] The at least one coolant line can be designed for guiding a coolant and / or a refrigerant. In correspondence therewith, the at least one coolant line can also be referred to as a cooling line in general. That is, both a coolant and a refrigerant can be used in the cooling device of the battery for cooling the battery cells and can be conveyed through the at least one coolant line.

[0017] In particular, the pressure plate can have a first passage opening for a coolant line designed as a coolant inflow and a second passage opening for a coolant line designed as a coolant outflow. The coolant can be introduced into a cooling plate of the cooling device by means of such a coolant line, for example, and be guided away from the cooling plate again, two stacked battery cells being arranged on the cooling plate. The coolant can be supplied to a cooler of the motor vehicle via the coolant line guided through the passage opening of the pressure plate by means of a further coolant line and can be supplied to the cooling plate again after passing through the cooler.

[0018] The further coolant line leading to the cooler of the motor vehicle and leading away from the cooler can here in particular extend parallel to a vehicle longitudinal axis of the motor vehicle and be arranged substantially centrally in the direction of a vehicle transverse axis of the motor vehicle. This can also be advantageous for protecting the further coolant line from possible damage. Furthermore, in particular in a motor vehicle designed as an electric vehicle, there is installation space in the longitudinal direction of the motor vehicle in the vehicle center region in order to install the coolant line of the vehicle leading to the cooler and leading away from the cooler.

[0019] It can be provided that the entire pressure plate consists of plastic. This makes the manufacture of the pressure plate particularly inexpensive.

[0020] Therefore, preferably, at least one base body of the pressure plate having an abutment region is composed of plastic. Thereby, a comparatively large and well loadable component in the form of a pressure plate can be provided in a particularly simple manner with little outlay and at low cost.

[0021] It can be provided that at least one insert composed of metal is introduced into the base body. At least one metal component of the battery can be fixed on the surface of the insert by welding. By providing such an insert composed of metal, which is embedded in the base body of the pressure plate, components, such as means for electrical contacting of the individual battery cells, which are also referred to as battery cell contact systems, and / or electrical connection lines for electrically connecting the battery modules of the battery to one another, can be fixed on the at least one insert by welding in a simple and low-outlay manner.

[0022] The pressure plate preferably has a first plate part and a second plate part, which form the pressure plate in the coupled state with one another. Thereby, a complex shaping of the pressure plate can also be realized in a particularly simple manner. Furthermore, the provision of the pressure plate from two plate parts is advantageous for a cost-effective production of the plate parts by means of plastic injection molding.

[0023] Therefore, in particular, the two plate parts can be designed as injection-molded parts. That is to say, the gate can be configured on the side of the respective plate part opposite the abutment region in the injection molding very easily. Thereby, the respective plate part can be ejected from the injection molding mold or injection molding tool in a particularly simple manner, wherein the ejection direction extends perpendicular to the abutment region. This in turn means that the abutment region can be configured very flat and oriented in the intermediate space perpendicular to the stacking direction. This is advantageous for a uniform pressure loading of the pressure plate.

[0024] If the two plate parts are designed identically, the pressure plate can be provided from the two plate parts with particularly little outlay. Since it is thus not necessary to provide different tools for the production of the respective plate parts in the injection molding method.

[0025] Preferably, the plate parts have corresponding form-locking elements. The form-locking elements engage into one another in the coupled state of the plate parts with one another. The mechanical coupling of the two plate parts in order to provide the pressure plate can thus be realized in a particularly simple manner.

[0026] Preferably, the two abutment regions are configured flat and oriented perpendicular to the stacking direction. Thereby, it can be particularly easily and largely avoided that pressure peaks occur within the pressure plate.

[0027] Preferably, the pressure plate has at least one threaded hole. A threaded pin can be screwed into the threaded hole for fixing at least one holding device of the battery on the pressure plate. Such a threaded hole can also be constructed particularly easily and with little outlay directly in the manufacture of the pressure plate in an injection-molding method. Furthermore, the possibility is thereby provided of fixing further components of the battery on the pressure plate in a particularly different manner.

[0028] Preferably, the first stack and the second stack are components of a battery module of the battery. Here, the battery module comprises a module frame which surrounds the two stacks of the battery module and which loads the two stacks of the battery module with pressure. Such a module frame can be provided by end plates on the end sides and tie rods or side walls which connect the end plates or the pressure plates on the end sides to one another.

[0029] If the module frame comprises two end-side pressure plates or end plates which are arranged at opposite ends of the two stacks, the pressure plate which is arranged in the intermediate space between the two stacks can also be referred to as an intermediate pressure plate.

[0030] Such a battery module with a module frame ensures that the battery cells arranged in the respective stacks are loaded with a pressure which, inter alia, largely prevents the walls of the housings of the individual battery cells from bulging during operation of the battery cells. This is advantageous for the operation of the battery cells in terms of the provision of electrical energy by the battery cells.

[0031] Preferably, the battery comprises a plurality of the battery modules which are electrically conductively connected to one another. In this way, a comparatively high voltage and / or - in particular when the battery is discharging - a comparatively high current strength can be provided by the battery.

[0032] It is particularly advantageous if the battery is designed as a high-voltage battery or high-voltage accumulator which provides electrical energy for a drive device, for example in the form of at least one electric motor of a motor vehicle. Such a high-voltage accumulator has a rated voltage of more than 60 volts and in particular up to several hundred volts.

The features and feature combinations mentioned above in the description and the features and feature combinations mentioned below in the figure description and / or shown alone in the figures can be used not only in the respectively indicated combinations, but also in other combinations or on their own.

[0039] Figure 6 Highly schematic representation of a motor vehicle with a battery, which has a plurality of Figure 1 battery modules as shown in DETAILED DESCRIPTION

[0040] In Figure 1 , a battery module 1 for a battery 2 of a motor vehicle 3 as shown in Figure 6 is shown in a schematic top view. The battery module 1 comprises a first stack 4 with a plurality of battery cells 5, only some of which are provided with reference numerals in Figure 1 for the sake of clarity. The battery cells 5 of the first stack 4 are arranged within a module frame 6 of the battery module 1. The module frame 6 ensures that the battery cells 5 in the first stack 4 are loaded with pressure in a stacking direction 7, which is shown by an arrow in Figure 1 .

[0041] The battery module 1 comprises a second stack 8 with a plurality of battery cells 5, which is surrounded together or jointly with the first stack 4 by the module frame 6 of the battery module 1. The two stacks 4, 8 of the battery module 1 are thus arranged within the module frame 6. In Figure 1 , only some of the battery cells 5 of the second stack 8 are provided with reference numerals. And also in the second stack 8, the battery cells 5 are loaded with pressure by the module frame 6, which acts in the stacking direction 7 of the battery cells 5 of the second stack 8.

[0042] In the intermediate space between the two stacks 4, 8 and especially at the middle between the two stacks 4, 8 as currently shown exemplarily, a pressure plate 9 is arranged, which is shown in Figure 3 in an exemplary variant and in perspective.

[0043] The pressure plate 9 currently has two through openings 10. The coolant lines 11, 12 of the cooling device 13 of the battery 2 can be guided through these through openings, which are shown schematically in Figure 2 . For the sake of clarity, the battery module 1 is shown only schematically in Figure 2 as square and without the details visible in Figure 1 .

[0044] The first coolant line 11 is designed, for example, as a coolant inflow for the cooling plate 14, through which the coolant can flow. Figure 2 The second coolant line 12 shown in is designed as a coolant outflow for the cooling plate 14.

[0045] When the battery cells 5 of the battery module 1 are in thermally conductive contact with the cooling plate 14, the coolant lines 11, 12 that pass through the through openings 10 of the pressure plate 9 are protected from damage in the pressure plate 9. As a result, the pressure exerted on the pressure plate 9 and the battery cells 5 in the stacking direction 7 does not act on the coolant lines 11, 12.

[0046] In the stacking direction 7, the pressure plate 9, which is configured as a plate-like or square component, currently has a smaller extension than in its vertical direction 29 and perpendicular to the plane formed by the stacking direction 7 and the vertical direction 29.

[0047] According to Figure 1 , the module frame 6 of the battery module 1 comprises a first end plate 15 arranged at an end side of the battery module 1 and a second end plate 16 opposite the first end plate 15 in the stacking direction 7. The end plates 15, 16 are connected to one another by means of the side walls 17, 18 of the module frame 6, in particular by means of welding the side walls 17, 18 to the respective end plate 15, 16. The side walls 17, 18 thus act as tie rods, which load the battery cells 5 and the pressure plate 9 of the two stacks 4, 8 with the pressure exerted in the stacking direction 7.

[0048] In the state in which the battery 2 is installed in the motor vehicle 3, the stacking direction 7 and thus the longitudinal extension direction of the battery module 1 can extend in particular parallel to the vehicle transverse axis y. Thereby, it is possible, in particular, for the pressure plate 9 to be arranged substantially centrally in the motor vehicle 3 in the direction of the vehicle transverse axis y. As a result, the coolant lines 11, 12 that pass through the through openings 10 of the pressure plate 9 are particularly well protected from damage in the direction of the vehicle transverse axis y.

[0049] In the direction of the vehicle longitudinal axis x, a plurality of Figure 1 battery modules 1 shown can be arranged side by side and electrically conductively connected to one another to form the battery 2 of the motor vehicle 3 (see Figure 1 ).

[0050] Since the battery modules 1 are electrically conductively connected to one another, the battery 2 of the motor vehicle 3 can in particular provide a high-voltage accumulator. Such a high-voltage accumulator has a rated voltage of more than 60 volts and in particular up to several hundred volts. In correspondence therewith, the battery 2 can provide electrical energy for a drive device, for example in the form of at least one electric motor 19 of the motor vehicle 3 (see Figure 6 ). The at least one electric motor 19 can drive wheels 20 of the motor vehicle 3 and thereby ensure a forward movement of the motor vehicle 3.

[0051] Cooling plates 14 arranged at the battery cells 5 below the respective stacks 4, 8 in the direction of the vehicle vertical axis z (see Figure 2 ) are supplied with coolant by one of the coolant lines 11, 12. Further coolant lines 21, 22 arranged above the battery cells 5 of the battery modules 1 in the direction of the vehicle vertical axis z (see Figure 5 ) are connected to the further coolant lines of the respective battery modules 1, which are currently extending in the direction of the vehicle longitudinal axis x and guide coolant to and from a (not shown) cooler of the motor vehicle 3.

[0052] From the perspective view of a possible variant of the pressing plate 9 shown in Figure 3 , it can also be seen that the pressing plate 9 can have threaded holes 23. Threaded pins 24 can be screwed into such threaded holes 23 (see Figure 5 ). The holding device of the battery 2 can be fixed to the pressing plate 9 by such threaded pins 24.

[0053] For example, a holder 25 can be fixed to the pressing plate 9 by such a threaded pin 24, which engages into the thread of one of the threaded holes 23 configured in the pressing plate 9 by injection molding. Via such a holder 25, the coolant lines 21, 22 can be fixed, for example, in the region of the pressing plate 9 (see Figure 5 ).

[0054] However, the pressing plate 9 also makes it possible to fix other components or other interfaces of the battery 2 in the region of the pressing plate 9. For example, according to Figure 3 , an insert 27 composed of metal can be embedded in a base body 26 composed of plastic of the pressing plate 9. And a metal component of the battery 2 can be fixed by welding to a surface 28 of the respective insert 27.

[0055] For example, a metal component of a battery cell contact system can be welded to one of the inserts 27. Such a battery cell contact system ensures that the battery cells 5 of the battery modules 1 are electrically conductively connected to one another.

[0056] Furthermore, the high-voltage connector and / or the retainer for the high-voltage connector can be connected to one of the inserts 27 by welding. This high-voltage connector can establish a conductive connection between the corresponding battery modules 1 of the battery 2 and can therefore be designed as a module connector.

[0057] If in Figure 3 The platen 9 shown in the example is manufactured in a plastic injection molding method. The demolding direction along which the platen 9 is removed from the injection molding mold (not shown) can extend, for example, in the vertical direction 29 of the platen 9, which is preferably oriented parallel to the vertical axis z of the vehicle in the installation position of the battery module 1 in the motor vehicle 3.

[0058] However, this means that the contact area 30 or contact surface of the pressure plate 9, where the pressure plate 9 contacts the first stack 4 or the second stack 8, must be designed to be slightly inclined so that the pressure plate 9 can be easily demolded or removed from the injection molding mold. Accordingly, the corresponding contact area 30 is at least slightly inclined relative to the vertical direction 29.

[0059] However, considering the uniform application of pressure to the pressure plate 9, which contacts the corresponding battery cells 5 of the first stack 4 on one side and the second stack 8 on the other side adjacent to the contact area 30, the flattest possible construction of the contact area 30 and the orientation of the contact area 30 perpendicular to the stacking direction 7 are advantageous.

[0060] Therefore, when the pressure plate 9 is designed as a plastic injection molded part, the following variation can be achieved in particular, which utilizes... Figure 4 To explain, the pressure plate 9 includes two plate components 31, which are structurally identical and one of them is in... Figure 4 The diagram is shown schematically in perspective. Figure 4 The two plate components 31 shown can be coupled to each other. In the coupled state of the two plate components 31, the pressure plate 9 is provided through the two plate components 31.

[0061] In one of the plate components 31 Figure 4 In the exemplary design shown, a portion of the corresponding through-opening 10 of the pressure plate 9, i.e., a corresponding half of the current corresponding through-opening 10, is provided by one of the corresponding plate components 31. Furthermore, in each plate component 31, one of the two inserts 27 is embedded in the plastic substrate 26 of the corresponding plate component 31.

[0062] In addition, from Figure 4As can be seen, the plate parts 31 can have corresponding form-locking elements, which enable the coupling of the plate parts 31 to one another for providing the pressure plate 9. For example, a snap connection or a click connection can be implemented, in which the form-locking elements engage one another in order to form the pressure plate 9.

[0063] In Figure 4 the variant of the plate part 31 shown exemplarily in Figure 4 , the form-locking element corresponding to the convex projection 32 is provided by a concave recess 33, which is configured in the region of the second threaded hole 23 of the pressure plate 9 (cf. Figure 3 ).

[0064] By introducing the projection 32 into the corresponding recess 33 of the other one of the two plate parts 31, it can be caused that the plate parts 31 are held together for providing the pressure plate 9. It can be provided here that the respective projection 32 is introduced into the respective recess 33 perpendicular to the vertical direction 29. Additionally or alternatively, it can be provided that the projection 32 is pushed into the respective recess 33 in the vertical direction 29.

[0065] By means of Figure 4 the provision of the pressure plate 9 by two plate parts 31, it is caused that the manufacture of the plate parts 31 is particularly simply implemented by injection molding. For example, a pouring region or injection site can be configured in the central region 34 of the plate part 31, more precisely on the side of the plate part 31 opposite the abutment region 30.

[0066] Correspondingly thereto, the demolding of the plate part 31 from the (not shown) injection molding mold can be implemented perpendicular to the abutment region 30 or to this planar outer surface of the plate part 31. In this way, a particularly planar configuration of the abutment region 30 of the respective plate part 31 and an orientation of the abutment region 30 perpendicular to the stacking direction 7 can be particularly easily implemented.
