    Description [0001] This invention relates to an electric battery module, the module having flat electrochemical cells disposed in a housing between thermally conductive separator plates and configured to power vehicles having an electric or hybrid drive unit.
    Both terminals of the cells used in the modules of this type are designed as band electrodes, which are guided by a body of a cell as two thin metal sheets, the first of aluminum and the second of copper. Such a pole construction creates a problem of effective electrical connection between the two electrochemical cells that are closest to each other in a battery module. It results from the fact that the distances between the cells are small and the materials making up the band electrodes have different electrochemical properties and that an electrochemical cell is produced in their contact point in the presence of moisture, the cell being a starting point of Corrosion and an increase in the resistance of the connection is. This increased resistance of the connected poles generates energy losses and increases the heat energy generated at the site of the connection. This increased heat energy causes the rapid oxidation of the aluminum part of the compound and the even greater increase in resistance. For this reason, in the known solution concepts cell poles are connected by means of supporting and covering mold-forming elements.
    From US2008 / 0124617 a module of batteries is known, in which the ends of electrodes which are connected, are clamped for better utilization of the space by means of supporting and covering and forming elements. In addition, the ends of electrodes which are connected are separated by a plate made of an electrically non-conductive material, the plate having two rows of longitudinal guide openings which ensure the proper arrangement of connected electrodes before being electrically connected and clamped ,
    Furthermore, from W02010 / 071463 a module of electric batteries is known in which flat electrochemical cells are arranged in a housing between thermally conductive partition plates, which touch the side wall of the housing. In this known solution concept, the ends of electrodes which are connected are also separated from each other by means of a plate consisting of an electrically non-conductive material, the plate having two rows of longitudinal guide openings.
    It is an object of this invention to provide a connector constructed such that band electrodes are reliably and stably connected to each other on a large area to obtain a permanent electrical connection characterized by a small resistance value ensures better utilization of the space, and to allow easy installation of the cells in modules as well as to put them into operation with less chance of accidental short circuits.
    An electric battery module having flat electrochemical cells disposed in a housing between thermally conductive separator plates contacting a side wall of the housing in which band electrodes of neighboring cells through a terminal comprising a supporting and forming member and a covering and forming member are joined, characterized in that the supporting and forming element is mounted on the thermally conductive partition plate placed between the connected band electrodes of the cells.
    The supporting and mold-forming element is advantageously mounted on the thermally conductive partition plate by means of a longitudinally directed mounting slot, which is executed in a bottom of the element.
    The thermally conductive partition plate is advantageously displaceable in a longitudinally directed Austrian Patent Office AT13 620U1 2014-05-15
    Attachment slot of the supporting and forming element used.
    The supporting and shape-forming element is advantageously connected by thermocompression bonding with the thermally conductive partition plate.
    The supporting and shape-forming element is advantageously adhered to the thermally conductive partition plate.
    The supporting and shape-forming element as well as the covering and forming element advantageously have curved shaping surfaces.
    In an advantageous embodiment, there are a supporting and forming element and / or a covering and forming element made of plastic.
    In a further advantageous embodiment, a module has a high-current terminal and a measuring terminal.
    As a result, a plate made of an electrically non-conductive material having lead openings of electrode ends has been eliminated and replaced by a supporting and forming element fixed on the thermally conductive partition plate, the space has been better utilized, and the terminals at the electrode ends can be joined together more easily.
    In this specification, the term " forming element " each element having a voluminous profile surface other than a flat surface, which element provides an arc profile of the ribbon electrodes when connected by clamping.
    Embodiments of this invention are shown in the drawing, in which: FIG. 1 FIG. 2 FIG. 3 FIG. 4 FIG. 5 FIG. Figure 6 shows a connector of band electrodes of electrochemical cells in a perspective view before clamping; shows a similar connector in a perspective view after clamping; shows a supporting and forming element in a perspective view; shows a covering and forming element in a perspective view; shows an example of a high current terminal in a perspective view; shows a battery module in a partial section through screws which clamp a supporting and forming element and a covering and forming element; FIG.

    View from the connector side.
    Before connecting the band electrodes of the electrochemical cells 1, a connector, as shown in Fig. 1, a supporting and forming element 2, which is mounted on a thermally conductive partition plate 7, and a covering and forming element 3 with Band electrodes 4, 5 of these two adjacent electrochemical cells 1, which are located between the elements, said band electrodes 4, 5 have an electrical contact with each other and wrapped on the supporting and forming element 2 and by means of clamping elements, which are designed as screws 6 are pressed by the covering mold-forming element 3. The supporting shape-forming element 2 and the covering and forming element 3, which are shown in Fig. 1, have curved mold-forming surfaces. FIG. 2 shows a further connector for band electrodes of the electrochemical cells 1, in which the supporting and forming element 2 is fastened by thermocompression bonding on the thermally conductive separating plate 7 is.
    In further embodiments of this invention, the supporting and forming element 2 is attached by gluing on the thermally conductive partition plate 7.
    In Fig. 3, an embodiment of the supporting and forming element 2 is shown having an outer curved mold-forming surface. This shape-forming and supporting element 2 has a slot 11 and openings 8 for the screws 6, while a length of the shape-forming element is adapted to be approximately in accordance with a width of the band electrodes 4, 5. In order to reduce the likelihood of accidental short-circuiting both when mounting a connector and during operation, the supporting and mold-forming element 2 is fixed by means of the slot 11 on the thermally conductive partition plate 7, and it is made of plastic, e.g. Polypropylene.
    In Fig. 4, the covering and forming element 3 is shown together with its inner curved mold-forming surface. This covering and forming element 3 has openings 9 for the screws 6. A length of this covering and mold-forming element 3 matches the length of the supporting and forming element 2, which cooperates with the covering and forming element 3. The covering and forming element 3 is made of plastic for similar reasons as the supporting and forming element 2, e.g. Polypropylene.
    In order to incorporate adjacent battery modules into the set of modules, according to the invention, the first connector designed to be connected to a positive band electrode of a cell that is uppermost in the battery module and the last connector that is designed are also included to be connected to a negative band electrode of a cell, which is the lowest in the battery module, additionally equipped with high current terminals 12. An example of the shape of the high current terminal 12 is shown in FIG.
    In Fig. 6, a part of the battery module is shown in a section through the clamping screws and by the supporting and forming element 2 and the covering and forming element 3. As shown in Fig. 6, the electrochemical cells 1 are stacked and thermally separated by the thermally conductive partition plates 7 mechanically connected to a housing 15 of the module, and the band electrodes 4, 5 of the electrochemical cells 1 are around the forming and wrapped supporting elements 2, which are mounted on the thermally conductive partition plates 7, and are pressed by the covering and forming elements 3. In the illustrated embodiment, the screws 6 act as elements that clamp the supporting and forming element 2 and the covering and forming element 3. In addition, the battery module has measuring terminals 10 and the high current terminals 12.
    In Fig. 7 is a cross section of the assembled battery module 13 is shown. The module 13 comprises the housing 15 with a stack of eight flat electrochemical cells 1 arranged in the housing between the thermally conductive partition plates 7 in mechanical contact with walls of the housing 15. In this module, the band electrodes 1 and 2 of the neighboring cells are connected to each other by a clamp connector. The clamp connectors have the supporting and mold-forming elements 2 fixed on the thermally conductive partition plates 7 and the covering and mold-forming elements 3 pressed against them by the clamping screws 6.
    In Fig. 8, a single battery module 13 is shown in an exploded view from the side of the connector forth. In order to connect the electrochemical cells 1 of the battery module 13, the band electrodes 4, 5 are placed in pairs around the supporting and forming elements 2 and pressed by means of the screws 6 through the covering and mold-forming elements 3. Thereafter, an electronic board 14 is added, which detects the voltage from all Meßklemmanschlüssen 10 of the electrochemical cells 1 3/9 Austrian Patent Office AT 13 620 Ul 2014-05-15, and then this board is connected to a battery monitoring system.
