Description

Battery device for supplying energy to a traction drive of a partially electrically operated vehicle
Technical Field
The present invention relates to a battery arrangement for supplying energy to a traction drive of an at least partially electrically operated vehicle. The battery device comprises a module device having a battery module for receiving a battery cell and two longitudinal members between which the module device is arranged, and at least one cross member device connecting the longitudinal members to each other.
Background
In addition to powering the traction drive, the battery device of an electric or hybrid vehicle must also satisfy 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 the event of an accident, the battery is often a particularly deformed and severe component. Deformation may lead to leakage of the medium and even to fires. In addition, the battery generally contributes to overall body rigidity. The battery should require as little installation space as possible and as light weight as possible. Last but not least, the battery should also be produced as cost-effectively as possible by inexpensive industrial processes.
Disclosure of Invention
In contrast, it is an object of the present invention to provide an improved battery arrangement for an at least partly electrically operated vehicle.
This object is achieved by a battery device having the features described below. Preferred improvements of the present invention are also described below. Additional advantages and features of the invention will be set forth in the general description and in the description of exemplary embodiments.
The battery device according to the invention is used for supplying energy to a traction drive of an at least partially electrically operated vehicle, in particular an electric vehicle and/or a hybrid vehicle. The battery device comprises at least one module device having a battery module for receiving a battery cell. The battery device includes at least two longitudinal members. The modular device is arranged between the longitudinal members. The battery means comprises at least one cross member means. The cross member arrangement connects the longitudinal members to each other (in a supporting manner). In particular, the longitudinal member and the cross member arrangement are fastened to each other. The cross-member means are provided by at least one housing body and at least two console bodies for housing the battery control electronics unit. The housing bodies are integrated in a supporting manner between the console bodies and are used in particular for the transverse connection of the longitudinal members. The cross-member arrangement comprises at least one support geometry for supporting the cross-member arrangement on the module arrangement in a defined (linear and/or planar) manner. In particular, this way, in the event of a crash, the cross-member arrangement absorbs accident-related force effects at least in part and transmits them in particular through the support geometry (in particular to the preceding module arrangement).
The battery device according to the invention provides a number of advantages. The cross-member arrangement provides significant advantages in that the housing body for the battery control electronics unit also performs a structural task. Thereby saving installation space and weight. Meanwhile, the structural design of the cross member device formed by the shell main body and the console main body realizes low production cost and economy of the battery device. A significant advantage is that the cross-member arrangement also contributes significantly to the protection of the battery in the event of a collision. By integrating the support geometry into the cross-member device, a particularly even and broad distribution of accident-related force effects is achieved. Thus effectively avoiding serious deformation of the battery module or at least reducing it to an allowable level. In addition, reliable protection is provided against penetration of objects through the modular arrangement. The housing body for the control electronics unit functionally provides a correspondingly large compression zone.
Preferably, the cross member means is arranged behind the module means (in particular in the longitudinal direction or the travelling direction). In particular, this way, in a rear collision, the cross-member arrangement absorbs accident-related force effects at least partially and transmits them to the front module arrangement, in particular via the support geometry. The cross member arrangement is in particular fastened to the end regions of the longitudinal members. In particular, the cross member arrangement is supported on the longitudinal member. In particular, the longitudinal member is also supported on the cross member arrangement. In particular, the cross member arrangement completes the battery arrangement (rear side). In particular, the cross member arrangement and the longitudinal members form a frame structure surrounding the module arrangement. In particular, the cross member means protrude beyond the module means at both ends in the transverse direction.
The battery device may comprise at least one (further) cross-member device arranged in front of the module device in the longitudinal or travelling direction, such that in a front collision the cross-member device is located to at least partially absorb accident-related force effects and to selectively transfer them to the following module device via the support geometry.
It is also preferred and advantageous if the support geometry can be supported linearly and/or planarly on the module arrangement in the event of a crash. The term "linear support" is understood in particular to mean that the support along the line also extends to some extent over the width. In particular, no punctiform support is provided. The modular device can thus be protected by the housing body and the console body, the latter not having to be provided with cumbersome or structurally expensive reinforcements.
In a preferred and advantageous development, the support geometry can be supported at least on the upper and lower lateral side regions of the module arrangement in the event of a crash. This achieves a particularly good support. The lateral side regions of the module arrangement extend in particular in the lateral direction.
In the context of the present invention, the information about the direction or axis relates in particular to the vehicle coordinate system having a longitudinal axis (X-axis; longitudinal direction), a transverse axis (Y-axis; transverse direction) and a vertical axis (Z-axis; vertical direction) and the intended state of assembly of the battery device in the vehicle. The transverse direction corresponds in particular to the longitudinal axis of the cross-member arrangement.
The support geometry preferably comprises at least two support sections which extend sectionally (in the transverse direction) along the transverse member device and are in particular spaced apart from one another. In particular, the support geometry comprises at least one support section for supporting in an upper lateral side region and at least one support section for supporting in a lower lateral side region of the modular device. The support section is in particular elongate. The support section enables in particular a linear support. The support section may also be part of the support surface. In particular, the respective length of the support section is at least half, preferably at least three-quarters, particularly preferably at least 90% of the length of the housing body, preferably of the overall length of the cross-member arrangement.
Preferably and advantageously, the support geometry is provided on the housing body at least by at least one housing wall facing the module arrangement. In particular, the housing wall provides a support section of the housing body. The housing wall extends in particular in the vertical and transverse directions. The housing wall is in particular planar. The housing wall may include protrusions and/or recesses for providing a support geometry. The housing wall has a length of in particular at least three-fourths and preferably at least 90% of the length of the housing body.
It is also advantageous and preferred that the support geometry is provided on the console body at least by at least one upper support projection and at least one lower support projection, respectively. The support protrusion provides, inter alia, a support section of the console body. In particular, the support protrusion is integrally formed with the console body. In particular, the support protrusions extend in the lateral direction. The support protrusions are preferably hollow. It is possible and preferred that the support protrusions have a respective length of at least three fourths and especially at least 90% of the length of the console body.
In an advantageous embodiment, the console body is correspondingly designed as a carrying arm. The carrier arm extends in particular from the housing body to the longitudinal member without lateral support (in an unsupported manner). In particular, the load-bearing arm does not comprise or only comprises a shorter section of the support geometry. The console body is then connected to the housing body, in particular integrally. It has been shown that due to the integral connection with the housing body, a reliable and firm support on the console body can be achieved even without support geometry. However, the console body may also provide a significant portion of the support geometry.
The housing body comprises, inter alia, at least one protective plate for preventing accident-related objects from penetrating. In particular, the protective plate is arranged opposite the support geometry of the housing body. The protective plate may be used as a housing cover for maintaining the opening. In particular, the protective plate extends parallel to the housing wall, which provides a support geometry on the housing body.
In a particularly advantageous development, the battery modules of the module arrangement are at least partially connected to one another in a supporting manner, so that the module arrangement is self-supporting. In combination with such a modular arrangement, the present invention provides particular advantages.
In particular, the battery modules are connected to each other in a supporting manner at least in the transverse direction and preferably also in the longitudinal direction. The battery modules may be connected to each other indirectly or directly. In particular, the module arrangement forms a self-supporting battery structure of the battery arrangement together with the longitudinal member and in particular also with the at least one cross member arrangement.
The module arrangement preferably comprises a plurality of module row arrangements arranged one after the other in the longitudinal direction. In particular, the module row arrangement comprises at least two battery modules arranged adjacent to each other in the transverse direction, respectively. Preferably, the module row arrangements are each designed as a self-supporting connection between the longitudinal members.
The module row arrangement is preferably fixedly connected to the longitudinal member at the ends, respectively. In particular, the module row arrangement is supported on the longitudinal member. Preferably, the module row arrangements are also connected to each other in a supporting manner. For example, adjacent module row arrangements are fastened to each other (indirectly or directly).
The cross member arrangement is preferably arranged behind (in the longitudinal or travelling direction) the last module row arrangement. In particular, the cross member means protrude beyond the last module row means at least in the transverse direction and preferably at both ends. In particular, the cross-member arrangement may be supported on the last module row arrangement.
It is possible and advantageous to design the console body as a common part. In particular, the console body is identical. The console body may also be similar, e.g., mirror symmetrical. In particular, the support geometry is then also arranged on the side of the console body facing away from the modular device. The common portion may thus be selectively attached to the left or right side of the housing body. The common part may be provided with different mechanical working. The common portion may be formed separately or may be integrally connected to the housing main body.
The console body and/or the housing body are manufactured, in particular, by a casting process. In particular, a continuous casting process and/or a die casting process is provided. In particular, the console body and/or the housing body are made of a light metal material, and preferably made of aluminum. Plastic materials or steel may also be used. In particular, the support protrusions are designed as hollow substructures of a continuously cast profile.
It is possible and advantageous if the console body and the housing body are designed as separate components which can be fixedly connected to one another. The console body is then in particular designed as a continuously cast component.
It is also possible and advantageous for the console body and the housing body to be integrally connected to one another. In particular, the console body and the 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 carrying arm.
In all configurations, it is preferred that the cross-member arrangement has at least one attachment point. The attachment points are used in particular for fastening the cross-member device to the main body and/or for fastening the main body substructure to the cross-member device. In particular, at least one attachment point is used to support the console. For example, the main body bottom structure may comprise a protective plate for the modular device.
The transverse member arrangement proposed here is particularly suitable and designed to protect the battery module in front of it from accident-related deformations and accident-related objects penetrating, in particular in rear collisions and preferably also in side collisions. The cross member arrangement is particularly suitable and designed to stabilize or support the battery module in the longitudinal direction and in the transverse direction together with the longitudinal member and in particular also with the self-supporting module arrangement. The cross member arrangement is particularly suitable and designed to absorb forces acting transversely on the longitudinal members and/or to support and connect the longitudinal members to each other in the transverse direction.
The battery device is designed in particular as a high-voltage battery. The battery device may also be referred to as a traction battery. The battery device is designed in particular as a main body bottom battery. In particular, the battery device may be mounted between two body longitudinal members. The longitudinal member of the battery device may at least partially provide the body longitudinal member and/or may be provided in addition to the body longitudinal member. The battery control electronics unit comprises in particular at least one power electronics unit. Applicant reserves the right to claim an at least partially electrically operated vehicle having a battery device according to the invention.
The console body provides, inter alia, attachment of the cross member arrangement to the longitudinal member. The console body and the housing body are connected to each other, in particular in a supporting manner. The console body and the housing body are in particular connected to each other such that the cross member arrangement is a support part. The cross member arrangement may also be referred to as an impact absorber.
In particular, the housing body and console body together provide a support geometry. It is also possible that only the housing body provides the support geometry. The console body is then preferably designed to be integral with the housing body.

Detailed Description
Fig. 1 shows a battery device 1 according to the invention for powering a traction drive of an electric vehicle or a hybrid vehicle, which is not shown in more detail here. The battery device 1 comprises a modular device 2 with battery modules 12 in which battery cells 42 (not visible here) are grouped together.
The modular arrangement 2 is here self-supporting. For this purpose, two battery modules 12 arranged next to each other in the lateral direction are fixedly connected to each other, respectively, to form a module row arrangement 22. The module row 22 here extends in the transverse direction or transversely to the travel direction 20. The module row arrangements 22 are likewise fixedly connected to one another. The battery modules 12 are thus connected to each other in a supporting manner in the lateral direction and also in the longitudinal direction. The modular device 2 is fastened to the longitudinal member 3 and is here partially covered by a panel 32.
The battery control electronics unit 10 (not visible here) arranged inside the housing body 5 is located behind the module arrangement 2 in the direction of travel 20 together with the power electronics unit.
In addition to the self-supporting modular arrangement 2, a cross-member arrangement 4 is provided here for supporting the longitudinal member 3. As a result, the battery is supported in both the lateral direction and the longitudinal direction. The cross-member arrangement 4 is formed by a housing body 5 and two console bodies 6 fastened thereto.
The housing body 5 is attached to the longitudinal member 3 via a console body 6. The installation space required for the battery control electronics unit 10 is designed here in a compact manner such that it does not require the entire width between the longitudinal members 3. The console body 6 bridges the distance from the housing body 5 to the longitudinal member 3 and thus enables integration of the housing body 5 functions into the support structure of the cross member device 4.
Together with the console body 6, the housing body 5 forms a structural geometry 7 for supporting the cross member arrangement 4 on the module arrangement in a defined manner in a rear collision. At the same time, the housing body 5 and the console body 6 together provide protection for the last module row arrangement 22 against excessive deformation and against penetration of objects in the event of an accident.
The structure of the cross-member arrangement 4 will now be presented in more detail with reference to fig. 1 to 4. The support geometry 7 here extends over the housing body 5 and over the console body 6. The support geometry here comprises two support sections 17 extending in the transverse direction along the cross-member device 4 and spaced apart from each other. As can be seen clearly in fig. 3 and 4, the support section 17 provides support in the upper lateral side region as well as in the lower lateral side region of the last module row arrangement 22.
Fig. 3 shows a cross section through the battery device 1 in the region of the console body 6. Here, the support geometry 7 formed on the console body 6 can be clearly seen. On the console body 6, the support geometry 7 is here provided by upper and lower support protrusions 27. The support protrusions 27 are here hollow and are part of a continuously cast profile providing the console body 6.
The console body 6 is here designed as a common part 16 so that they can be fastened selectively to the left or right side of the housing body 5. Suitable machining for the left or right side may be provided. For this purpose, the common part 16 is here designed with identical support protrusions 27 on two opposite lateral sides.
Fig. 4 shows a cross section through the battery device 1 in the region of the housing body 5. The support geometry 7 formed on the housing body 5 can be seen particularly clearly here. The housing wall 37 facing the last module row arrangement 22 serves as a support geometry 7 for the housing body 5. The housing wall 37 here provides two support sections 17 which are supported in particular in the upper and lower lateral side regions of the module row arrangement 22 in a rear collision. The battery control electronics unit 10 inside the housing body 5 is summarized here.
In order to avoid that in the event of a rear collision an object penetrates the housing body 5 or even the front module arrangement 2, a protective plate 15 is provided here. The latter simultaneously serves as a housing cover and enables access to the battery control electronics unit 10. The protective plate 15 is arranged on the side of the housing body 5 opposite to its support geometry 7.
The cross-member arrangement 4 is here provided with attachment points 8, 18. The upper attachment point 8 is here for example for fastening to a body or for supporting a console. The lower attachment point 18 is used to secure the body bottom structure 28, for example, as shown in fig. 3 and 4.
Fig. 5 shows an alternative design of the cross-member arrangement 4, which may also be used in the above-described battery arrangement 1, for example. The housing body 5 and the console body 6 are integrally connected to each other here. The cross-member arrangement 4 is here designed, for example, as a die-cast component made of aluminum.
In the embodiment shown here, the console body 6 is designed as a carrying arm 26 extending from the housing body 5 to the longitudinal member 3 without support geometry 7 and without lateral support on the remaining components. The support geometry 7 is here provided only by the support section of the housing body 5.
Such a configuration has an advantage that the console body 6 is omitted from being mounted on the housing body 5. The elimination of the interface between the housing body 5 and the console body 6 also generally results in a smaller tolerance for attachment to the longitudinal member 3. Furthermore, the attachment points 8, 18 can thus also be manufactured more easily and flexibly.
