    The invention relates to a fastening device for at least one battery module, in particular for at least one battery module of an electric vehicle, having a support structure with at least one battery module engaging under supporting part, wherein the battery module is firmly connected to the support structure.
    It is known to mount battery cells or battery modules on profile carriers. Furthermore, it is known to attach battery modules on continuous metal support plates.
    US 2009/226806 A discloses a fastening device for batteries in a vehicle, wherein a battery pack is fastened by screws to the vehicle floor. A similar arrangement is known from EP 1 850 407 A1.
    Low-voltage batteries are usually connected via clamping devices to the body of the vehicle, as known for example from the publications KR 2001-0093501 A, KR 100 680 543 Bl or DE 10 2006 026 619 Al. Such clamping devices are not suitable for high voltage batteries for safety reasons.
    The KR 2001-0092493 A discloses a fastening device for a vehicle battery, wherein the attachment via the battery passing through mounting rods, which can be positively connected to vehicle-mounted tabs. However, this type of attachment is less suitable for high voltage batteries of an electric vehicle for safety reasons.
    Furthermore, it is known to perform the attachment of the batteries on the vehicle via frame-like structures, see for example CN 101 710 613 A or KR 2006-0091948 A. Such support structures, however, have the disadvantage of a high weight, which is the desire as high as possible weight-related energy densities reach, oppose.
    The object of the invention is to avoid the disadvantages mentioned and to attach batteries, especially high-voltage batteries, in a simple and secure manner to the body of a vehicle, with the highest possible weight-related energy densities to be achieved.
    According to the invention this is achieved in that the battery module via at least one battery module penetrating fastener, preferably a fastening screw, with at least one support member positively or non-positively connected, preferably screwed, with particular preference - 2 ~ way, the fastener disposed predominantly within the battery module is.
    To protect the battery module can be provided that the battery module is arranged in a battery case, wherein at least one preferably elongated support member is disposed outside of the battery case in a bottom portion of the battery case.
    A particularly secure attachment is made possible when the support member has at least one threaded hole for receiving the fastening screw, wherein the fastening screw is guided from the battery module to the support member and preferably the fastening screw - with the exception of engaging in the threaded bore of the carrier threaded end - arranged entirely within the battery case is.
    A cost-effective attachment can be accomplished if the support member is formed by a preferably closed hollow profile, particularly preferably by an extruded profile. A secure connection of the battery modules to the support member can be achieved when the threaded hole is formed by a disposed within the support member threaded insert. The threaded inserts can have at least one tool holder in order to allow the screw connection of the battery modules to hold the threaded insert.
    The fastening screws are guided from the inner region of the housing through the battery module and through holes in the battery housing to the outside to the support member and bolted to it. This allows a largely thermal decoupling of the battery cells from the support structure. A further improvement of the thermal insulation can be achieved if at least one sealing device is arranged between the supporting part and the battery housing and / or between the battery housing and the battery module. For a secure and stable storage of the battery module, it is advantageous if the support structure has at least two, preferably at least three preferably parallel arranged supporting parts, wherein preferably the battery housing has at least one preferably rail-like recess or indentation for receiving a support member, wherein preferably the cross section the recess or recess is adapted to the profile shape of the support member.
    A particularly secure attachment can be achieved if the support member and / or the recess has a trapezoidal - or wedge-shaped profile. Due to the trapezoidal or wedge-shaped cross-section, the battery module, including the battery housing, can be connected to the carrier structure without play, so that a stable and accident-proof attachment in the vehicle is ensured.
    A secure connection of the support structure to the body can be achieved if at least one support member is firmly connected to at least one end of the battery module projecting end to the body of the vehicle, preferably screwed.
    In order to keep the weight as low as possible and to achieve high weight-related energy densities, it is advantageous if the support member made of aluminum or plastic, preferably made of polyamide.
    A particularly good heat decoupling between the battery modules and the battery housing or the body can be achieved if the battery module is thermally decoupled from the support structure, preferably between the battery module and the battery housing at least one heat-insulating part, preferably a foamed part, is arranged.
    The invention will be explained in more detail below with reference to FIGS.
    1 shows a fastening device according to the invention for a battery in an oblique view, and FIG. 2 shows the fastening device in a section along the line II-II in FIG. 1.
    Fig. 1 shows a battery case 1, which is fixedly connected to a support structure 2 having a fastening device 3. The support structure 2 consists of several parallel to each other arranged support members 4, 5, 6, which may be formed for example by extruded aluminum. Alternatively, the support members 4, 5, 6 may be made of plastic, such as polyamide.
    Within the battery housing 1, at least one of a plurality of battery lines exhibiting battery module 7 is arranged, which is connected via a plurality of formed by fastening screws 8 elongate fasteners directly frictionally with the support members 4, 5, 6. The elongated support members 4, 5, 6 are arranged outside of the battery housing 1 in the bottom portion la, wherein the battery housing 1 according to the profile of the support members 4, 5, 6 formed rail-like recesses or recesses 9 to the support members 4, 5, 6 record.
    The fastening screws 8 penetrate the battery module 7 and are respectively screwed into threaded bores 10 of the support part 4, 5, 6. The threaded holes 10 may be formed by threaded inserts 11, which are in the - 4 - a hollow profile forming support members 4, 5, 6 transversely to the longitudinal axis 4a, 5a, 6a used. The fastening screws 8 are guided from the inside to the outside through holes 12 of the battery module 7 and through openings 13 of the battery case 1 and firmly screwed to the threaded inserts 11. For thermal decoupling of the battery module 7 from the support structure 2 sealing means 15 are provided between each support member 4, 5, 6 and the battery housing 1, which are formed by O-rings, silicone inserts, EPTM (ethylene-propylene-diene monomer), or the like can. Optionally, the thermal decoupling can be improved by the use of heat-insulating material, for example by a foamed part, between the battery module 7 and the battery case 1 without the connection is adversely affected to the support structure 2.
    In order to be able to counteract when tightening or loosening the fastening screws 8, each threaded insert 11 has tool receptacles 14 in the region of the outer side 14a facing away from the battery module.
    In the exemplary embodiment, the support parts 4, 5, 6 carried out extended beyond the battery case 1, so that the extended end portions 4b, 5b, 6b firmly connected to the body of the vehicle, not shown, for example, can be screwed.
    By the described support structure 2, a high weight-related energy density can be achieved, since the use of supporting metal parts can be reduced to a minimum. Nevertheless, a secure attachment of the relatively high battery weight in the vehicle under the usual operating conditions, especially in the event of a crash, guaranteed. The support structure 2 is very simple and inexpensive to manufacture and can be bolted directly to the body of the vehicle.
    A significant advantage is the good thermal insulation of the battery modules 7 to the outside, which is particularly important for cold start and operation or standstill at hot temperatures of great importance.
