    The invention relates to a pole bridge for a rechargeable battery, in particular a vehicle battery for an electric vehicle, with at least one cooling device thermally connected to the pole bridge,
    From DE 12 48 769 B, an electrode connection for electric storage batteries is known, in which the plates are held by clamping between parts of a Polkbrücke provided with multiple pole bridge, wherein in the pole bridge, a channel for receiving coolant is provided.
    Battery bridges with integrated cooling channels are further known from GB 2 068 633 A.
    Furthermore, from the publications JP 2006-271 063 A2 and JP 2005-071 674 A2 polar bridges for batteries with existing cooling fins cooling devices are known, which are designed as heat to the environment emitting cooling fins.
    Particularly in the case of high-voltage batteries used in electric vehicles, temperature management for temperature control of the batteries with a powerful cooling system is unavoidable.
    The object of the invention is to ensure optimal temperature control of a battery as simple and safe as possible.
    According to the invention this is achieved in that the cooling device has at least one cooling channel, wherein the cooling channel can be formed as a separate component and firmly connected to the pole bridge.
    The cooling device serves to temper the battery, wherein at cold ambient temperatures, the cooling device can also be used to warm the battery.
    In order to avoid short circuits and electrical leakage currents, it is provided that at least one electrically insulating first layer is arranged between the cooling channel and the pole bridge, wherein preferably the cooling channel and / or the pole bridge are at least predominantly encased by an electrically insulating second layer. The second layer surrounding the pole bridge and / or the cooling channel may also be formed by a foil or a shell, for example made of plastic.
    A particularly simple manufacture and assembly can be achieved if the cooling channel is fixed by an electrically insulating adhesive, preferably a double-sided adhesive film, on the pile bridge. In this case, the electrically insulating first layer may be formed as an adhesive film. The adhesive bond between the cooling channel and the pole bridge ensures a stable thermal connection, wherein different thermal expansions between the pole bridge and the cooling channel are compensated.
    A particularly reliable heat dissipation can be achieved if the cooling channel is connected to a fluid circuit of a cooling system and / or heating system, wherein preferably at least one radiator and / or a heat sink is arranged in the fluid circuit. Depending on the ambient temperature and operating condition, this will allow the battery to warm up to operating temperature or to cool.
    The cooling channel may be made of copper or light metal, such as aluminum or an aluminum alloy. Alternatively, it is also possible that the cooling channel consists of an electrically non-conductive material. In this case, temperature-resistant plastics or ceramic materials can be used as the material for the cooling channel. A simple production can also be achieved if the cooling channel made of plastic is designed as an injection molded part, wherein preferably at least two injection-molded half parts are welded together, for example friction-welded.
    In a continuation of the invention can also be provided that the cooling channel is formed integrally with the surrounding the pole bridge insulating second layer, wherein preferably the Kühikanal is formed by the pole bridge at least predominantly surrounding film or shell.
    As insulating layer, a plastic, such as polyamide can be used.
    The cooling channel can - at least predominantly - have a circular, oval, elliptical, triangular, rectangular or n-angular closed profile, wherein preferably a contact surface with the pole bridge is just ausgeiidet. Optionally, the contact surface can also be machined. A particularly simple production can be achieved if the cooling channel is formed by a tube squeezed at least on one side. In order to optimize the contact surface between the cooling channel and the pole bridge, it is advantageous if the cooling channel is produced by means of a hydroforming method.
    The pole bridge can for example consist of copper or aluminum or an aluminum alloy. • * .- 3: -: r * * * ♦ *
    In order to achieve a sufficient heat transfer between the pole bridge and the cooling channel, it is advantageous if the cross section of the cooling channel is at least 30%, preferably at least 50% of the cross section of the pole bridge.
    The insulating plastic layer may be formed by half-shells welded together.
    In the context of the invention may further be provided that in the pole bridge at least one control electronics module is integrated.
    The invention will be explained in more detail below with reference to the schematic FIG.
    The Fig. Shows in a sectional oblique view of an existing aluminum or copper pole bridge 1 for a rechargeable battery, not shown, for example, a high-voltage battery of an electric vehicle, wherein on the top la of the pole bridge 1, a cooling channel 2, which, for example, aluminum or an aluminum alloy can exist, is captively fastened. For electrical insulation, an electrically insulating first layer 3 is arranged between the cooling channel 2 and the pole bridge 1, which may be made of plastic, for example, by a double-sided adhesive film.
    The cooling channel 2 is connected to a fluid circuit, not shown, of a cooling and heating system. The cooling or heating system not shown has a likewise not shown cooling or radiator, for example, a heat exchanger and / or an electrical heating and / or cooling element. The electrical heating and / or cooling element may be formed for example by a Peltier element. As a result, the battery can be kept very effectively in the optimum operating temperature range.
    Furthermore, the pole bridge 1 and the cooling channel 2 are surrounded by an electrically insulating second layer 4, wherein the second layer 4 may be formed by welded shells 4a, 4b made of plastic.
    The adhesive bond between the cooling channel 2 and the pole bridge 1 ensures a stable thermal connection, wherein different thermal expansions between the pole bridge 1 and the cooling channel 2 are compensated. This is a very robust and compact design feasible.
    The cooling channel 2 can be made entirely of plastic or formed by the insulating second layer 4 itself. The plastic channel 2 may also be formed by an extruded plastic profile.
    In the case of a metallic cooling channel 2, hydraulic shaping (hydroforming) is advantageous in order to optimize the thermal contact surface between the cooling channel 2 and the pole bridge. In a simple construction, the cooling channel 2 can also consist of a flat pressed oval aluminum profile tube.
    Optionally, a control electronics module can be integrated into the pole bridge 1.
