Description

Technical Field

[0001] The present invention relates to a battery device for supplying energy to the traction drive of a vehicle that is at least partially electrically operated. The battery device includes a module assembly having a battery module for receiving battery cells, two longitudinal members arranged therebetween, and at least one transverse member assembly connecting the longitudinal members to each other. Background Technology

[0002] In addition to supplying power to the traction drive, the battery packs in electric or hybrid vehicles must meet many other diverse and complex functions. For example, one of these requirements is to protect the battery cells in the event of a collision. In an accident, the battery is often a particularly severely deformed component. Deformation can lead to leakage or even fire. Furthermore, the battery should generally contribute to the overall rigidity of the vehicle. The battery should require the smallest possible installation space and the lightest possible weight. Last but not least, the battery should also be manufactured as cost-effectively as possible through inexpensive industrial processes. Summary of the Invention

[0003] In contrast, the object of the present invention is to provide an improved battery device for a vehicle that is at least partially electrically operated.

[0004] This objective is achieved by a battery device having the features described below. Preferred improvements of the invention are also described below. Additional advantages and features of the invention will become apparent from the general description and the description of exemplary embodiments.

[0005] The battery device according to the invention is used to supply energy to the traction drive of at least partially electrically operated vehicles, particularly electric vehicles and / or hybrid vehicles. The battery device includes at least one module device having a battery module for receiving battery cells. The battery device includes at least two longitudinal members. The module device is arranged between the longitudinal members. The battery device includes at least one lateral member device. The lateral member device connects the longitudinal members to each other (in a supporting manner). In particular, the longitudinal members and the lateral member device are fastened to each other. The lateral member device is provided by at least one housing body for housing a battery control electronics unit and at least two console bodies. The housing body is integrated in a supporting manner between the console bodies and is particularly used for the lateral connection of the longitudinal members. The lateral member device includes at least one supporting geometry for supporting the lateral member device on the module device in a defined (linear and / or planar) manner. In particular, in the event of a collision, the lateral member device at least partially absorbs the force effects associated with the accident and specifically transmits them (particularly to the forward module device) through the supporting geometry.

[0006] The battery device according to the invention offers numerous advantages. The lateral member device provides significant advantages, wherein the housing body for the battery control electronics also performs a structural function. This saves installation space and weight. Simultaneously, the structural design of the lateral member device, consisting of the housing body and the control unit body, results in low and economical production costs for the battery device. A significant advantage is that the lateral member device also significantly contributes to battery protection in the event of a collision. By integrating the supporting geometry into the lateral member device, a particularly uniform and widespread distribution of accident-related force effects is achieved. This effectively prevents severe deformation of the battery module or at least reduces it to an acceptable level. Furthermore, reliable protection is provided against objects penetrating the module device. The housing body for the control electronics functionally provides a correspondingly large compression zone.

[0007] Preferably, the lateral member assembly is arranged at the rear of the module assembly (particularly in the longitudinal or traveling direction). In particular, in a rear-end collision, the lateral member assembly at least partially absorbs the accident-related force effects and specifically transmits them to the forward module assembly via the supporting geometry. The lateral member assembly is particularly fastened to the end regions of the longitudinal members. Specifically, the lateral member assembly is supported on the longitudinal members. Specifically, the longitudinal members are also supported on the lateral member assembly. Specifically, the lateral member assembly completes the battery assembly (rear side). Specifically, the lateral member assembly and the longitudinal members form a frame structure surrounding the module assembly. Specifically, the lateral member assembly protrudes laterally beyond the module assembly at both ends.

[0008] The battery assembly may include at least one (additional) lateral member assembly arranged in front of the module assembly in the longitudinal or travel direction, such that in a frontal collision, the lateral member assembly is positioned to at least partially absorb the accident-related force effects and selectively transfer them to the module assembly behind it via support geometry.

[0009] Equally preferred and advantageous is that, in the event of a collision, the supporting geometry can be linearly and / or planarly supported on the modular unit. The term "linear support" should be understood in particular to mean that the support along the line also extends to some extent in width. In particular, no point support is provided. The modular unit can therefore be protected by the housing body and the console body, the latter of which need not be equipped with bulky or structurally expensive reinforcements.

[0010] In a preferred and advantageous improvement, the support geometry can provide support at least on the upper and lower lateral side regions of the modular unit in the event of a collision. This provides particularly good extensive support. The lateral side regions of the modular unit extend especially in the lateral direction.

[0011] In the context of this invention, information regarding direction or axis particularly relates to a vehicle coordinate system having a longitudinal axis (X-axis; longitudinal direction), a lateral axis (Y-axis; lateral direction), and a vertical axis (Z-axis; vertical direction) and the intended assembly state of the battery device in the vehicle. The lateral direction particularly corresponds to the longitudinal axis of the lateral component assembly.

[0012] The support geometry preferably comprises at least two support segments that extend segmentally (in the lateral direction) along the transverse member assembly and are particularly spaced apart from each other. Specifically, the support geometry includes at least one support segment for support in the upper lateral side region and at least one support segment for support in the lower lateral side region of the modular assembly. The support segments are particularly elongated. The support segments are particularly capable of achieving linear support. The support segments may also be part of a support surface. In particular, the corresponding length of the support segment is at least half, preferably at least three-quarters, and particularly preferably at least 90% of the total length of the transverse member assembly, the length of the housing body.

[0013] Preferably and advantageously, the supporting geometry is disposed on the housing body at least by at least one housing wall facing the modular device. In particular, the housing wall provides a supporting section for the housing body. The housing wall extends particularly in the vertical and transverse directions. The housing wall is particularly planar. The housing wall may include protrusions and / or recesses for providing the supporting geometry. The length of the housing wall is at least three-quarters, and preferably at least 90%, of the length of the housing body.

[0014] Also advantageously and preferably, the supporting geometry is provided on the console body by at least one upper supporting protrusion and at least one lower supporting protrusion, respectively. The supporting protrusions particularly provide supporting sections for the console body. Specifically, the supporting protrusions are integrally formed with the console body. Specifically, the supporting protrusions extend in the lateral direction. The supporting protrusions are preferably hollow. Possibly and preferably, the corresponding length of the supporting protrusions is at least three-quarters, and especially at least 90%, of the length of the console body.

[0015] In an advantageous construction, the console body is correspondingly designed as a load-bearing arm. This load-bearing arm extends specifically from the housing body to the longitudinal members without lateral support (in an unsupported manner). In particular, the load-bearing arm does not include or only includes a short section supporting the geometry. The console body is then integrally connected to the housing body. It has been shown that, due to this integral connection with the housing body, reliable and robust support can be achieved on the console body even without a supporting geometry. However, the console body can also provide a significant portion of the supporting geometry.

[0016] The housing body particularly includes at least one protective plate for preventing accident-related object penetration. Specifically, the protective plate is arranged opposite to the supporting geometry of the housing body. The protective plate can serve as a cover for a maintenance opening. In particular, the protective plate extends parallel to the housing wall, providing supporting geometry on the housing body.

[0017] In a particularly advantageous improvement, the battery modules of the modular device are at least partially connected to each other in a supportive manner, making the modular device self-supporting. Combined with such a modular device, the present invention offers numerous advantages.

[0018] Specifically, the battery modules are connected to each other in a supporting manner, at least in the lateral direction and preferably also in the longitudinal direction. The battery modules can be connected to each other indirectly or directly. In particular, the module assembly, together with the longitudinal member and especially with at least one lateral member assembly, forms a self-supporting battery structure for the battery assembly.

[0019] The modular assembly preferably comprises multiple module rows arranged one after another in the longitudinal direction. Specifically, each module row comprises at least two battery modules arranged adjacent to each other in the transverse direction. Preferably, the module rows are designed with self-supporting connections between longitudinal members.

[0020] The modular assembly is preferably fixedly connected to the longitudinal member at its ends. Specifically, the modular assembly is supported on the longitudinal member. Preferably, the modular assemblies are also connected to each other in a supporting manner. For example, adjacent modular assemblies are fastened to each other (indirectly or directly).

[0021] The transverse component assembly is preferably arranged behind the last row of modules (in the longitudinal or traveling direction). Specifically, the transverse component assembly protrudes beyond the last row of modules, at least in the transverse direction and preferably at both ends. In particular, the transverse component assembly may be supported on the last row of modules.

[0022] Designing the console body as a common part is possible and advantageous. Specifically, the console bodies are identical. The console bodies can also be similar, for example, mirror-symmetrical. In particular, the supporting geometry is then also arranged on the side of the console body opposite the modular assembly. The common part can therefore be selectively attached to the left or right side of the housing body. Different machining processes can be provided for the common part. The common part can be formed independently or integrally connected to the housing body.

[0023] The console body and / or housing body are manufactured, in particular, by a casting process. Specifically, continuous casting and / or die casting processes are provided. Specifically, the console body and / or housing body are made of a lightweight metal material, and preferably of aluminum. Plastic materials or steel may also be used. Specifically, the support protrusions are designed as hollow substructures of continuously cast profiles.

[0024] It is possible and advantageous that the console body and the outer shell body are designed as independent components that can be fixedly connected to each other. The console body is then specifically designed as a continuously cast component.

[0025] It is also possible and advantageous to integrally connect the console body and the housing body. Specifically, the console body and housing body are then molded together and manufactured together, particularly in a casting process. In particular, a die-casting process is then provided. In such a configuration, the console body is preferably designed as a support arm.

[0026] In all configurations, it is preferred that the transverse component assembly has at least one attachment point. The attachment point is particularly used for securing the transverse component assembly to the main body and / or for securing the main body's bottom structure to the transverse component assembly. Specifically, at least one attachment point is used to support a control console. For example, the main body's bottom structure may include a protective plate for the modular assembly.

[0027] The lateral member device proposed herein is particularly suitable and designed to protect the battery module in front of it from accident-related deformation and accident-related object penetration, especially in rear-end collisions and preferably also in side-end collisions. The lateral member device is particularly suitable and designed to stabilize or support the battery module in the longitudinal and lateral directions together with the longitudinal member and especially also with a self-supporting module device. The lateral member device is particularly suitable and designed to absorb lateral forces acting on the longitudinal member and / or to support and connect the longitudinal members to each other in the lateral direction.

[0028] The battery device is particularly designed as a high-voltage battery. The battery device may also be referred to as a traction battery. The battery device is particularly designed as a battery at the bottom of the main body. Specifically, the battery device can be mounted between two main body longitudinal members. The longitudinal members of the battery device can at least partially provide the main body longitudinal members and / or can be provided in addition to the main body longitudinal members. The battery control electronics unit particularly includes at least one power electronics unit. The applicant reserves the right to claim protection for vehicles having at least partial electric operation of the battery device according to the invention.

[0029] The console body particularly provides attachment of the transverse component assembly to the longitudinal component. The console body and the housing body are particularly connected to each other in a supporting manner. The console body and the housing body are particularly connected to each other such that the transverse component assembly is a supporting member. The transverse component assembly can also be referred to as an impact absorber.

[0030] Specifically, the outer casing and the console body together provide the supporting geometry. Alternatively, only the outer casing may provide the supporting geometry. The console body is then preferably designed to be integral with the outer casing.

[0050] Other advantages and features of the present invention arise from the exemplary embodiments explained below with reference to the accompanying drawings.

[0056] Figure 5 A detailed representation of another battery device according to the invention is shown in a perspective view from an oblique angle. Detailed Implementation

[0057] Figure 1 A battery device 1 according to the invention is shown for supplying power to the traction drive of an electric or hybrid vehicle, which is not shown in more detail herein. The battery device 1 includes a module device 2 having a battery module 12, in which battery cells 42 (not visible herein) are grouped together.

[0058] The module unit 2 is self-supporting. For this purpose, two battery modules 12 arranged adjacent to each other in the lateral direction are fixedly connected to each other to form a module row unit 22. The module row unit 22 extends in the lateral direction or laterally to the direction of travel 20. The module row unit 22 is also fixedly connected to each other. Thus, the battery modules 12 are connected to each other in a supporting manner in both the lateral and longitudinal directions. The module unit 2 is fastened to the longitudinal member 3 and is partially covered by the panel 32.

[0059] The battery control electronics unit 10 (not visible here), located inside the main body 5, is positioned behind the module device 2 along with the power electronics unit in the direction of travel 20.

[0060] In addition to the self-supporting module 2, a transverse component 4 is provided to support the longitudinal component 3. As a result, the battery is supported in both the transverse and longitudinal directions. The transverse component 4 is formed by the outer casing 5 and two console bodies 6 fastened thereto.

[0061] The housing body 5 is attached to the longitudinal member 3 via the console body 6. The installation space required for the battery control electronics unit 10 is designed in a compact manner, so that it does not require the entire width between the longitudinal members 3. The console body 6 spans the distance from the housing body 5 to the longitudinal member 3 and thus makes it possible to integrate the functions of the housing body 5 into the support structure of the transverse member device 4.

[0062] Together with the console body 6, the outer shell body 5 forms a structural geometry 7 for supporting the lateral component assembly 4 on the modular assembly in a defined manner during a rear-end collision. Simultaneously, the outer shell body 5 and the console body 6 together provide protection for the rearmost modular assembly 22 against excessive deformation and against object penetration during an accident.

[0063] Now refer to Figures 1 to 4 The structure of the transverse component assembly 4 is presented in more detail. The supporting geometry 7 extends above the outer casing 5 and the console body 6. The supporting geometry includes two support segments 17 that extend laterally along the transverse component assembly 4 and are spaced apart from each other. Figure 3 and 4 As can be clearly seen, the support section 17 provides support in the upper and lower lateral regions of the last module assembly 22.

[0064] Figure 3A cross-section through the battery assembly 1 is shown in the region of the console body 6. Here, the supporting geometry 7 formed on the console body 6 can be clearly seen. On the console body 6, the supporting geometry 7 is provided here by upper and lower supporting protrusions 27. The supporting protrusions 27 are hollow and are part of the continuous cast profile providing the console body 6.

[0065] The console body 6 is designed here as a common part 16, allowing it to be selectively fastened to the left or right side of the housing body 5. Suitable machining can be provided for the left or right side. For this purpose, the common part 16 is designed here to have identical support protrusions 27 on both opposite lateral sides.

[0066] Figure 4 A cross-section through the battery assembly 1 in the region of the housing body 5 is shown. The supporting geometry 7 formed on the housing body 5 can be seen particularly clearly here. The housing wall 37 facing the last module assembly 22 serves as the supporting geometry 7 of the housing body 5. Here, the housing wall 37 provides two support segments 17, which specifically support the upper and lower lateral side regions of the module assembly 22 in a rear-end collision. The battery control electronics unit 10 inside the housing body 5 is summarized here.

[0067] To prevent objects from penetrating the housing body 5 or even the front module unit 2 in the event of a rear-end collision, a protective plate 15 is provided. The latter also serves as a housing cover and allows access to the battery control electronics unit 10. The protective plate 15 is arranged on one side of the housing body 5 opposite to its supporting geometry 7.

[0068] The transverse component assembly 4 is equipped with attachment points 8 and 18. The upper attachment point 8 is used, for example, for fastening to the main body or for supporting the control console. The lower attachment point 18 is used for fastening the bottom structure 28 of the main body, for example, as... Figure 3 and 4 As shown in the image.

[0069] Figure 5 An alternative design for the transverse component 4 is shown; for example, it can also be used in the battery device 1 described above. The housing body 5 and the console body 6 are integrally connected to each other. The transverse component 4 is designed here, for example, as a die-cast part made of aluminum.

[0070] In the embodiment shown here, the console body 6 is designed as a support arm 26 extending from the outer shell body 5 to the longitudinal member 3 without a supporting geometry 7 and without lateral support on the remaining components. The supporting geometry 7 is provided here solely by the support section of the outer shell body 5.

[0071] This construction has the advantage of eliminating the need to mount the console body 6 onto the housing body 5. The elimination of the interface between the housing body 5 and the console body 6 also results in smaller tolerances for attachment to the longitudinal member 3. Furthermore, it allows for easier and more flexible manufacturing of attachment points 8 and 18.
