    专利说明:

    The invention relates to a battery pack for the electrical power supply with a plurality of round cells in mutually offset rows, wherein the round cells have electrical poles, and with a projecting at least partially over the poles of the round top and bottom plate, which are connected to the round cells for a mechanical cohesion and have openings for air cooling of the round cells.
    From the prior art (EP2154740A2), a battery pack with a plate-shaped electrical insulator is known, which serves as a cover and bottom plate provided for holding the round cells of the battery pack. The round cells are inserted with their poles between these two insulators in recesses and are interconnected by sheet-shaped electrical line contacts, which protrude through openings of the top and bottom plate to the poles of the round cells. In order to achieve a temperature control of the round cells of the battery pack, openings for air cooling are possible in the insulator, among other things. This embodiment of a battery pack is comparatively complicated to manufacture, also the packing density of the round cells is relatively low and the space requirement of the battery pack thus high.
    The invention has therefore, starting from the above-described prior art, the task of providing a battery pack with a relatively high packing density of round cells available, the high performance requirements reliably and consistently meet, with adverse temperature changes, such as these in particular during charging , as well as the discharge of the battery pack can occur, are largely limited. In addition, the battery pack should be resistant to mechanical influences and ensure versatility, in particular with regard to the possible formation of a modular connection of several of these battery packs, which is a composite battery.
    The invention solves this problem by the fact that the electrically conductive cover and bottom plate are connected to the poles of the round cells both electrically and materially.
    If the electrically conductive top and bottom plates are connected to the poles of the round cells both electrically and integrally, a sturdy and inexpensive battery pack can be made available. In this way, an electrical circuit of battery cells, in contrast to the prior art in a much simpler manner, so with little effort and / or less aids done. In addition, a cohesive bonding of the poles of a round cell with a bottom and / or cover plate not only has the advantage of a particularly high stability, but so can also a relatively firm cohesion of the components of a battery pack, as well as its compact design allows. According to the invention, therefore, a high mechanical stability and load capacity of the battery pack can be achieved - in particular, of course, even if the round cells are arranged adjacent to each other and in mutually offset rows, as this results in a particularly compact design. In addition, advantages for the battery pack according to the invention may result with respect to the nature of its surface. Namely, it is possible to provide a substantially planar surface of an electrically conductive top and / or bottom plate, with any depressions in those areas of the top and / or bottom plate in which they are connected to poles of batteries. As a result of this configuration, battery packs can be connected to one another in a simplified manner to form a battery by being arranged one above the other, for example, for a parallel and / or series connection. In addition, the cover plate and / or base plate common to all round cells can provide for improved thermal cooling of the round cells or for equalization of the circular cell temperature. -3-
    If at least one spacer is provided between the round cells and between the top and bottom plates, among other things, the stability of the battery pack can be improved. Thus, it may also be advantageous, especially in comparatively large battery packs, to use spacers in order to pre-connect batteries, insulator and / or cover and base plate, for example frictionally, in order subsequently to ensure a secure and simple cohesive connection of poles with cover plates. and bottom plate to ensure. In particular, at high packing density of batteries in a Battehepack, as this can be achieved for example in mutually offset rows of round cells, spacers can also help to avoid adverse temperature increases in the battery pack or at least limit. In order to keep the design effort low, spacers are to be preferred, which have the same shape as the batteries of the battery pack, and a longitudinally continuous bore for the purpose of air circulation.
    If the cover plate and baseplate have openings in the region of a spacer, and if holding means accessible to the spacer via these openings are attached for fastening the battery pack, the assembly of a battery pack can be simplified, among other things. In addition, according to the invention a possibility can be used to improve or facilitate the battery pack to be positioned and / or fastened - for example on a housing, which is to receive one or more battery packs. It is also conceivable to use such holding means to connect several battery packs for the purpose of a circuit with each other. It is therefore within the scope of the invention to use such holding means to switch battery packs in parallel or in series and / or otherwise used to connect multiple battery packs to a battery and / or switch.
    If a plate-shaped electrical insulator is provided between the cover plate and the round cells and / or between the base plate and the round cells, which at least partially covers the areas between their contact points, it is possible in a simple manner to electrically insulate or pol- ish poles of a round cell. Shield to facilitate their connection to a deck or floor slab. As a result, those parts or regions of poles of a round cell with the aid of recesses, in particular round holes, can also be determined in a targeted manner and kept accessible for connection, in particular welding, with a cover plate or base plate which is required or desired. In this way, a battery pack with particularly high density of batteries can be provided, since the so improved connecting poles of a battery with a top or bottom plate much easier and more accurate can be done and thus any damage to batteries in the course of Connecting, in particular welding, can be reduced or prevented. Thus, functional impairments of a battery pack can be avoided, for example, due to short circuits improved. In addition, such insulation in the manner of a carrier for a top and / or bottom plate act and be ensured so that bottom and cover plate can be simplified and also connected in largely arbitrary shape with the poles of the batteries. In particular, it has been found to be advantageous that the top and bottom plates can be designed to a much smaller thickness, since an insulating layer can already provide them with a certain degree of stability. A cost-effective due to the reduced cost of materials and yet stable and variable to design device can thus be created. It is conceivable that insulation and deck or floor plates are formed as separate parts or as at least partially two- or multi-layer unit in the manner of a circuit board and are connected to the battery pack or the battery cells. In contrast to the prior art, a reliable battery pack can thus be made available in a simplified manner, which also requires comparatively little space due to its high packing density and high performance.
    If the round cells abut one another and the openings for air cooling of the round cells are arranged above the gaps lying between the round cells, a particularly high packing density of battery cells can be achieved without neglecting the cooling of a battery pack. According to the invention, namely, when battery cells are formed as round cells and arranged in mutually offset rows adjacent to each other, the gap between each three adjacent battery cells are used to ensure air flow through the battery pack for the purpose of temperature regulation. Thus, adverse effects of elevated temperatures of a battery pack on its stability, performance and / or other properties can be reduced. In particular, such a temperature control course of advantage for those battery cells, which are arranged in the region of the center of a battery pack and thus surrounded by a plurality of battery cells. Thus, according to the invention, such gaps between round cells are used for temperature regulation, in that if these gaps are covered by an insulator, by a cover plate or base plate, openings corresponding to the gaps are provided. However, it is of course also other arrangements of battery cells within the scope of the invention, such as those in which the battery cells are not arranged adjacent to each other directly touching each other.
    If the top and / or bottom plate each form at least one protruding contact surface which at least partially bounds the battery pack on the shell side, a particularly advantageous modular usability of a battery pack can be ensured. In this way, a plurality of battery packs according to the invention can then be successively positioned and simply interconnected via contact surfaces, without having to provide elaborate or additional constructions - in the case of several protruding contact surfaces, an interconnection would also be possible from front and / or long sides of battery packs become. It is conceivable and within the scope of the invention, also depending on the design of the round cells used for a battery pack to form the insulation accordingly, so that this insulation is also at least partially below a formed of cover and / or bottom plate shell. Thus, in addition and without much effort about an improved edge protection for a battery pack can be formed. In addition, in this way, the cohesion and stability of a battery pack can be improved, which in terms of its use under loads such as vibrations, etc., may be essential. Thus, according to the invention, a cost-effective and space-saving battery pack with high stability can be ensured.
    If a battery pack has a contact surface on opposite sides of the jacket, a serial connection of a plurality of battery packs can be carried out in a simple manner. Thus, such trained battery packs, for example, relatively easily arranged next to each other are connected in series by these are strung together so that the contact surface of the cover plate of a battery pack with the contact surface of the bottom plates of the subsequent battery pack are electrically connected - the bottom and cover plate of the battery pack course different are poled. Thus, it is also possible in a simplified manner to interconnect battery packs of the same type with each other serially.
    A battery can be formed from a plurality of electrically interconnected battery packs by the juxtaposed battery packs are electrically connected to each other via their respective contact surfaces. Such a battery can be characterized as particularly compact, powerful and stable. In addition, in a comparatively simple manner, the production of a battery with a desired power and / or capacity can be carried out by the respectively required number of battery packs is connected to each other. Since a connection of the battery pack according to the invention can allow any parallel and / or series circuits, it is also possible to make this battery spatially comparatively variable and adapt to the particular circumstances and requirements. Furthermore, such a battery can also be produced comparatively inexpensively and, owing to its modular structure, whereby a battery pack can be regarded as a single module, is also particularly cost-effective in its maintenance, in particular with regard to any required replacement of individual modules. -7-
    If the top and bottom plates of battery packs arranged next to one another are covered by electrically insulating carrier plates, which carrier plates are fixedly connected to spacers of at least one battery pack by means of connecting means, a layer of battery packs can be easily produced which make possible a connection to a multi-layered battery can.
    The invention further comprises a battery comprising a plurality of layers of battery packs arranged side by side and connected in series, an electrically insulating carrier plate being provided between the layers and the layers of the battery packs being electrically connected to one another via flexible connection lines. Thus, a compact and powerful battery can be provided, which can also be maintained improved, since there is a modular structure of a battery and, for example, if necessary, replaced layers with defective round cells and can be easily replaced.
    In the figures, for example, the subject invention is illustrated in more detail using an exemplary embodiment. Show it
    1 is a perspective view of a battery pack according to the invention,
    2 is a plan view of the embodiment of FIG. 1,
    3 is a sectional view according to III-III of FIG. 2,
    4 is a perspective view of a battery, comprising a plurality of battery packs,
    Fig. 5 is a partial sectional view of a battery of Fig. 4 to V-V and Fig. 6 is a battery of Fig. 4 in the unfolded state without support plates.
    Figure 1 shows, for example, a battery pack 1 for electrical power supply with a plurality of round cells 2, which are arranged in mutually offset rows. The round cells 2 have electrical poles 3, 3 'and are connected to a cover plate 5 projecting over the poles 3, 3' of the round cells, as well as base plate 6, as can be seen in particular from FIGS. In the exemplary embodiment, the ceiling 5 and base plate 6 protrude completely over the poles 3, 3 'of the round cells, which is not absolutely necessary. Ceiling 5 and bottom plate 6 contribute to a mechanical cohesion of the round cells 2 and thus of the battery pack 1 and also have openings 11, which mainly serve the air cooling of the round cells 2.
    Ceiling 5 and bottom plate 6 have an electrically conductive material and are connected to the poles 3, 3 'of the round cells 2 both electrically, as well as by welding material fit. The connection points 4, that is to say those region of the cover plate 5 which are connected to the poles of a round battery, form depressions 12 in the exemplary embodiment, which brings about the advantage described above that ceiling 5 and bottom plate 6 have substantially planar outer sides of the battery pack 1 form. Such recesses 12 can be introduced, for example by deep drawing in the ceiling 5 and bottom plate 6.
    Ceiling 5 and / or bottom plate 6 are preferably made of a nickel sheet, which can be distinguished by its advantages for a cohesive connection, in particular welding, with the poles of a battery of the battery pack. Namely, such a connection proves to be easy to manufacture and secure, so that a stable and powerful battery pack 1 can be provided.
    As can be seen in FIG. 1, a plate-shaped electrical insulator 10 is provided between the cover plate 5 and the round cells 2. The same would be conceivable for the bottom plate 6 and 2 round cells. Among other things, the insulator 10 serves the stability of the battery pack by largely fixing the arrangement and position of the round batteries in the battery pack. In addition, the insulator 10 at least partially covers the areas of the desired or required connection points on the battery poles 3, 3 ', whereby a secure and targeted connection of cover 5 and base plate 6 to the poles 3, 3' of a round cell can be ensured. -9-
    The round cells 2 of the battery pack 1 abut each other, whereby a particularly high packing density of the batteries 2 and thus a compact configuration of the battery pack 1 can be achieved. For the purpose of air cooling the round cells openings 11 are provided on the lying between the circular cells gaps, which protrude through the plate-shaped insulator 10 and the electrically conductive cover 5 and bottom plate 6. These openings 11 are positioned and formed so that air can flow largely freely through those gaps resulting from the successive positioning of round batteries in parallel staggered rows. Thus, it can be achieved, for example, by active air cooling, which is not shown in detail in the figures, that even tightly packed battery packs are sufficiently cooled, whereby a constant, consistent performance and an extended life of the battery pack is ensured.
    Between the circular cells 2 and between the cover 5 and bottom plate 6 at least one spacer 7 is provided. The spacers 7 substantially correspond in shape to those of a round cell. Cover and bottom plate 6 and the insulator 10 present in the exemplary embodiment have openings 8 in the region of the spacer 7, via which openings 8 holding means 16 associated with the spacer 7, for instance for additional fixing of base 5 or cover plate 6 to a round cell or to a round cell anderwärtigen attachment, mounting and the like of the battery pack 1 are accessible. In the case of the Battehepack 1 according to the invention, a cylindrically shaped piece of wood, for example, could be used as a spacer 7, into which bore 9, which at least partially penetrates the longitudinal axis, is received for receiving holding means 16. Accordingly, in this embodiment, such holding means are preferably helical, as can be seen in FIG. 5, and protrude into the spacers 7. In this way, a simple and secure connection of a battery pack 1, for example with a housing and / or with another battery pack according to the invention, can be produced. The spacers 7 can for example be used to support the assembly or assembly of a battery pack or for the temperature control of the battery pack 1, so they are preferably arranged in the region of the center of the battery pack 1, since there is usually a particularly high demand for Dissipation of heat exists.
    It is apparent in the embodiment of Figure 1 also that cover 5 and / or bottom plate 6 each have a contact surface 5 ', 6' protrudes, which at least partially forms a jacket of the battery pack. According to Figure 1, a particularly stable battery pack 1 is due to an edge protection formed thereby or a partial sheathing possible. A modular use of the battery pack 1 according to the invention can also be ensured since a plurality of these battery packs 1 can subsequently be positioned against one another and can simply be connected to one another in series via contact surfaces. In addition, in the exemplary embodiment, the insulation 10 also has a correspondingly shaped region 10 ', so that this insulation is also located under a jacket formed by cover and / or base plate.
    Tray the figures, the battery pack 1 on opposite sides of the shell each have a contact surface 6 ', 10' in order to facilitate a serial connection of several of these battery packs 1. Of course, it is also conceivable and within the meaning of the invention to form the battery pack 1 with another, such as a square, floor plan and / or provide the contact surfaces 6 ', 10' on end faces or on more than one shell side of a battery pack 1.
    Figure 3 shows a sectional view according to III-III of FIG. 2 - here, in particular, the connection points 4, ie those areas of the cover plate 5, which are connected to the poles of a round battery, and the corresponding recesses 12 recognizable. In addition, Figure 3 illustrates a spacer 7 with a bore 9. -11 -
    FIG. 4 shows a battery 12, comprising a plurality of battery packs 1, wherein the battery packs 1 arranged next to one another are electrically connected to one another via their contact surfaces 5 ', 6'. Furthermore, it can be seen that the cover 5 and bottom plates 6 juxtaposed battery packs 1 are covered by electrically insulating support plates 13, said support plates having, among other openings 14, above the holes 9 of the spacers 7, and the associated openings 8 of the deck -5 and / or bottom plate 6 lie. The same applies to openings 15 of the support plate 13, which are arranged above the openings 11 of deck 5 and bottom plate 6 and insulator 10 and thus associated with the gaps between adjacent round cells. Thus, according to the invention, a particularly advantageous air cooling of superimposed battery packs 1 of a battery 12 can be ensured, since the openings 11 and 15 are superimposed in such a way that advantageously a largely unobstructed air stream running vertically through the battery can be made possible - regardless of how the floor - 5 and cover plates 6 stacked battery packs are aligned with each other, as long as the battery packs are vertically aligned with each other.
    In particular, the figure 5 it can be seen that the support plates 13 are fixedly connected by means of connecting means 16 'with Abstandhaltem 7 of a battery pack 1, these compounds are designed in particular as a screw connection. In addition, it can be seen from FIG. 5 that holding means 16 can be used for the additional frictional connection of base 5 and cover plates 6 with a spacer 7 and thus for the improved mechanical stability of a battery pack.
    In addition, FIG. 5 shows that the layers 17 of battery packs 1 arranged side by side and connected in series are electrically connected to one another via flexible connecting lines 18, these connecting lines 18 being connected to the respective contact surfaces 5 'and 6' of the corresponding stacked battery packs a battery cohesively, in particular by welding, are connected together.
    In FIG. 6, the exemplary embodiment of a battery according to FIG. 4 is shown in the unfolded state without carrier plates 13, whereby the serial electrical circuit of the layers 17 of the battery and the advantages of the flexible connecting lines 18 can be seen in an improved manner. Preferably, since comparatively easy to perform, the support plates 13 are mounted in this embodiment only on the two end-side layers 17 and that on both sides. Thus, the above-described inventive advantages in terms of compactness, modularity, ease of maintenance - such as in the case of a possibly required replacement of individual battery packs 1 or layers 17 - a battery 12 are particularly clearly removed.
