    The invention relates to a battery, in particular secondary battery, with at least one cell or module carrier, with which at least one battery line or at least one consisting of a plurality of stacked battery cells battery module is thermally connected, wherein the cell or module carrier has at least one cooling channel.
    DE 10 2008 061 755 A1 describes a holding and cooling device for at least one energy storage unit, wherein the holding and cooling device has a plurality of materially secured thereto cooling plates. The cohesive connection is made by soldering or welding the cooling base plate to the cooling plates, so that a metallic connection between the cooling base plate and the cooling plates is formed. To cool the cooling base plate soldered or internal cooling tubes are provided. The problem is the reliable thermal connection of Wärmeableitbleche to the cooling plate.
    From WO 2011/076 940 Al an accumulator with a plurality of adjacently arranged voltage-generating cells is known, between which I- or H-shaped intermediate elements are arranged. In a further embodiment, plate-shaped intermediate elements are disclosed, which are arranged together with the cells in a support element. The Zwäschenelemente have ribs between which channels are designed to guide a heat carrier.
    US 2006/0115 719 describes a battery module with battery units arranged adjacent to one another between two end plates, the end plates being connected to one another by clamping screws. Spacer plates with cavities are arranged between the battery units.
    EP 1 117 138 A1 shows a battery pack with modular prismatic battery modules, which are arranged parallel to one another, wherein cooling channels arranged parallel to one another are formed by spacer plates between the battery modules. In one embodiment, the cooling channels are formed by closed square channels formed in the spacer plate, which are made in an extrusion or pultrusion process. In this case, each spacer plate on a plurality of parallel straight cooling channels, at the ends of each cooling channel is arranged in each case an inlet and an outlet for the cooling medium. This results in a large number of possible leaks, which increases the susceptibility to errors
    The object of the invention is to avoid these disadvantages and to enable the best possible thermal conditioning of the battery cells with low susceptibility.
    According to the invention this is achieved in that the cooling channel is poured into the cell or module carrier.
    A particularly low susceptibility due to leakage can be achieved if the cooling channel in the cell or module carrier has an inlet and an outlet, wherein preferably inlet and outlet are arranged on the same narrow side of the cell or module carrier. The susceptibility to errors is particularly favorably influenced by the fact that each cell or module carrier is integrally formed. The cell or module carrier should be a good heat-conductive material, for example metal, preferably of aluminum. In order to avoid leakage currents or short circuits, it is expedient to electrically isolate the cell or module carrier, wherein the surface of the cell or module carrier can be painted, powder-coated or foiled, for example.
    The cooling channel can be formed by an inserted casting core, which then forms the water space. Alternatively, it is also possible to form the cooling channel by an encapsulated tube, preferably made of metal, for example of aluminum, copper or steel.
    The inlet and outlet of the cooling channel of each cell or module carrier is fluidly connected to an inlet collection channel and an outlet collection channel, respectively. The cooling channels of at least two cell or module carriers are fluidly connected to each other through the inlet collection channel and the outlet collection channel.
    A particularly effective cooling is achieved if the cooling channel is guided in a meandering manner between an inlet and an outlet in several passes, wherein preferably the cooling channel of at least one cell or module carrier has a plurality of trains arranged essentially parallel to one another. 3
    In order to achieve a high structural rigidity, it is advantageous if at least one cell or module carrier has an I, C, double C, double T or H-shaped cross section.
    Depending on the application, at least one battery cell, preferably at least one battery module, or else on both sides of the cell or module carrier, at least one battery cell, preferably in each case at least one battery module, may be fastened on one side of the cell or module carrier. If appropriate, the battery cells or battery modules arranged on different sides of the cell or module carrier may also be arranged offset from one another. In certain applications, it may also be advantageous if the cell or module carrier is angled at least once in its longitudinal extent, preferably at least twice.
    A high degree of structural rigidity of the overall system can be achieved if at least two preferably spaced parallel cell or module carrier by at least one front-side connecting element, preferably by two arranged on opposite narrow sides of the cell or module carrier connecting elements are mechanically connected to each other ,
    A battery cell or a composite (battery module) of several such cells can be as simple and stable connected to the cell or module carrier when the battery cells are glued to the cell or module carrier, screwed or connected by clips.
    The invention will be explained in more detail below with reference to FIG.
    1 shows a cell or module carrier of a battery according to the invention in a section along line II in FIG. 2, FIG. 2 shows the cell or module carrier in a section according to line II-II in FIG. 1, and FIG. 3 to 6 batteries with different arrangements of cell and module carriers.
    1 shows a substantially I- or H-shaped cell or module carrier 1 of a battery, with battery cells 2 arranged on either side of the cell or module carrier 1, which battery cells 2 can be formed, for example, by metal can or pouch cells, or battery modules 20 , which consists of several consecutive or
    [Ριϋϋΐι ^^ β stacked battery cells 2 consist. The cell or module carrier 1 consists for example of aluminum and has a cooling channel 3, which is formed by a preformed and in the cell or module carrier 1 inserted and encapsulated tube 4, for example, copper, aluminum or steel. Alternatively, the cooling channel 3 (carrier including cavity) may also be formed by a lost core model (for example sand core).
    The arranged in the plane of symmetry la of the cell or module carrier 1 cooling channel 3 extends between the inlet 5 and the outlet 6 meandering in the cell or module carrier 1 in several parallel trains 7. inlet 5 and outlet 6 are on the same narrow side lb of the cell - or module carrier 1 is arranged. This minimizes the risk of leakage.
    In particular, with cell or module carrier 1 with C-profile battery cells 2 or battery modules 20 may be arranged only on one end face 8 of the cell or module carrier 1.
    In the case of cell or module carriers 1 with I-profile or H-profile (or double C or double-T-profile), at least one battery cell 2 (FIG. 2) can be provided on both end faces 8, 9 of the cell or module carrier 1 facing away from each other. 1) or at least one battery module 20 (FIGS. 3 to 6).
    Figs. 3 to 6 show possibilities of modular expandability within an entire battery.
    As FIG. 4 shows, a plurality of battery modules 20 can also be arranged in a grape pattern on both sides of the cell or module carrier 1 next to each other. Depending on the structural conditions, for example in a vehicle, the cell or module carrier 1 - adapted to the vehicle shape - be angled one or two times, with an offset of arranged on different sides battery modules can be beneficial.
    Furthermore, two or more cell or module carriers 1 arranged parallel to one another can be mechanically connected to one another on their narrow sides 1c, 1d by structurally stiff connecting elements 10, resulting in a high structural stiffening of the overall system (FIG. 6). ipiMi pü riMÖi ^ 502d2 5
    The cell or module carrier 1 consists of a cast blank which has a cooling channel 3 for liquid cooling in the interior. It has the task to position the battery cells 2 or battery modules 20, fix and temper (cool / heat). The battery cells 2 should lie as flat as possible on the carrier in order to create a good heat transfer. Cell or module carrier 1 and battery cells 2 and battery modules 20 can be connected to each other for example by means of gluing, screwing or by clips.
    The cell or module carrier 1 is produced by casting a thermally highly conductive, and mechanically stable material such as aluminum in a defined shape. The I or H profile results in a high bending stiffness. The cooling channels 3 are already produced during the casting process of the cell or module carrier 1. Cell or module carrier 1 and cooling channels 3 are executed in one part and not separable from each other. The compact unit of cell cooling and cell fixation enables low weight and easy manufacturability of large numbers,
    The cell or module carrier 1 with encapsulated cooling channel 3 allow a good uniform distribution of the temperatures of the individual battery cells 2. The large contact surfaces between battery cells 2 and cell or module carrier 1 allow a particularly good heat transfer.
    In order to avoid short circuits and leakage currents, the cell or module carrier 1 can be electrically insulated (for example by means of painting, powder coating,
    Foil, dipping, etc.).
