    [0001] Connection and distribution device for battery thermal management circuit Description. The present invention relates to battery thermal regulation and more particularly to a connection and distribution device for battery pack thermal management circuit or set of batteries.
    [0002] The thermal regulation of batteries, particularly in the automotive field and even more particularly electric and hybrid vehicles, is an important point because if the batteries are subjected to temperatures that are too cold, their autonomy can decrease sharply and if they are subjected to high temperatures. too important, there is a risk of thermal runaway that can lead to the destruction of the battery. In order to regulate the temperature of the batteries, it is known to add a device for regulating the temperature of the battery module. These devices generally use circulating heat transfer fluids, for example by means of a pump, in a duct circuit, said duct circuit passing in particular under or inside a heat exchange plate in direct contact with the batteries. . The heat transfer fluids can thus absorb heat emitted by the battery or batteries to cool them and evacuate this heat at one or more heat exchangers such as a radiator or a refrigerant. The heat transfer fluids may also, if necessary, provide heat to heat said batteries, for example if they are connected to an electrical resistance or heating by Positive Temperature Coefficient (PTC).
    [0003] The heat transfer fluids generally used are ambient air or liquids such as water. Liquids are better heat conductors than gases, it is a solution that is preferred because more effective.
    [0004] Nevertheless, there is a great diversity of battery packs or battery packs with different architectures within them which require particular connection and cooling configurations as required. Thus, it is difficult to standardize the connections between the battery packs or sets of batteries with the rest of the battery thermal management installation. One of the aims of the present invention is therefore to propose a connection and distribution device for a thermal management circuit of an improved and modular battery pack or battery pack.
    [0005] The present invention thus relates to a connection and distribution device for battery pack thermal management circuit or set of batteries placed within a protective box, comprising: - a base, - an input connector and an output connector heat transfer fluid placed on one side of the base and each comprising a heat transfer fluid circulation channel passing through said base, - an outlet orifice of each circulation channel on a face of the base distinct from that carrying the input connectors and output, - an injection coupler inserted and sealingly attached within the outlet of the flow channel of the inlet connector, said injection coupler being traversed by a circulation channel comprising at least two branches for supplying heat exchangers placed in contact with batteries, - an evacuation coupler inserted and sealed in the outlet orifice the flow channel of the output connector, said discharge coupler comprising at least one branch connected to the heat exchangers placed in contact with batteries.
    [0006] Such conformation of the connection and distribution device allows a better adaptability of the latter to different types of battery pack configuration or set of batteries. Indeed, in order to adapt to the circulation circuit within the battery pack or the set of batteries it is sufficient during the manufacturing process to choose the corresponding discharge or injection coupler and to fix it in a sealed manner at the base. According to one aspect of the invention, the base comprises a means for fixing an expansion valve on its face comprising the inlet connector and the heat transfer fluid outlet connector. According to another aspect of the invention, the base further comprises an enlargement, said enlargement comprising means for fixing said connecting device to a wall of the protective box, said base being intended to pass through said wall. According to another aspect of the invention, the enlargement comprises, on its circumference, a housing for placing a seal between said enlargement and the wall of the protective box. According to another aspect of the invention, the injection coupler comprises, upstream of the division of the flow channel passing through said injection coupler into at least two branches, a narrowing of the diameter of said circulation channel. According to another aspect of the invention, the injection and discharge couplers, as well as the base, are made of metal and the leaktight attachment of said injection and discharge couplers on the base is carried out by brazing.
    [0007] According to another aspect of the invention, the injection and evacuation couplers comprise a number of connections chosen as a function of the internal configuration of connections and circulation of the heat transfer fluid within the battery pack or the set of batteries. .
    [0008] According to another aspect of the invention, the input connector and the output connector have a different branching conformation. The present invention also relates to a battery pack thermal management installation or set of batteries comprising a connection device 15 as described above. Other features and advantages of the invention will appear more clearly on reading the following description, given by way of illustrative and nonlimiting example, and the appended drawings in which: FIG. 1 shows a schematic representation in perspective FIG. 2 shows a diagrammatic perspective view in plan view of the connection device of FIG. 1; FIG. Side view of the connection device of Figures 1 and 2, - Figure 4 shows a schematic representation of thermal management facility at battery packs of various configurations.
    [0009] The identical elements in the different figures bear the same references. Figures 1 to 3 show schematic representations of a connection device and distribution 1 heat transfer fluid respectively in a view from below, in top view and in sectional view. This connection and distribution device 1 is intended to allow the connection between a thermal management circuit and a battery pack 100 or a set of batteries 100 placed within a protective box as part of a thermal management installation. . Said connection and distribution device 1 comprises in particular: - a base 3, - a heat transfer fluid inlet connector 5, that is to say coming from the thermal management circuit, and a heat transfer fluid outlet connector 7, that is, heading towards the thermal management circuit. These input connectors 5 and output 7 are placed on one side of the base and each comprising a circulation channel 5o, 7o (visible in the sectional view of FIG. 3 of coolant passing through said base 3. In particular, the inlet 5 is intended to be placed downstream of an expansion valve of the thermal management circuit - an outlet orifice 52, 72 of each circulation channel on a face of the base 3 distinct from that bearing the input and output connectors 7, for example on the opposite side or on a side face, - an injection coupler 54 inserted and sealed in the outlet orifice 52 of the circulation channel 5o of the input connector 5, said injection coupler 54 being traversed by a circulation channel 54o comprising at least two branches 56, 58 intended to supply heat exchangers placed in contact with batteries 110, and an evacuation coupler 74 inserted and fi sealed in the outlet orifice 72 of the circulation channel 70 of the outlet connector 7, said exhaust coupler 74 comprising at least one branch connected to the heat exchangers placed in contact with batteries no. Such a conformation of the connection and distribution device 1 allows a better adaptability of the latter to different types of battery pack configuration 100 or battery pack 100. Indeed, to adapt to the circulation circuit within the battery pack loo or the set of batteries 100 it is sufficient during the manufacturing process to choose the corresponding discharge coupler 74 or injection 54 and to fix it tightly to the base 3. The injection couplers 54 and Evacuation 74 thus comprise a number of connections 56, 58 chosen as a function of the internal configuration of connections and circulation of the heat transfer fluid within the battery pack 20 or the set of batteries w 0 as shown in FIG. 4. The couplers injection 54 and discharge 74, as well as the base 3, can be made of metal and thus the sealing attachment of said injection couplers 54 and evacuation 74 on the base 3 can be realized e by brazing. For example, by means of a brazing ring placed in contact with the injection and discharge couplers 74 and the outlet orifice 52, 72 as illustrated in FIG. makes it possible to imagine other types of waterproof fastening such as a screwing, a force introduction or even simply a weld seam.
    [0010] The injection coupler 54 may comprise, upstream of the division of the circulation channel 54o passing through said injection coupler 54 in at least two branches 56, 58, a narrowing 542 of the diameter of said circulation channel 54o. This narrowing 542 creates a venturi effect within the circulation channel which allows a homogeneous flow of the coolant in the various branches 56, 58. The base 3 may also comprise a means 32 for fixing the expansion valve 10 to its face comprising the input connector 5 and the heat transfer fluid outlet connector 7. Said fastening means 32 may for example be a threaded orifice as illustrated in FIG. 1. The input connector 5 and the output connector 7 may also have a different branching conformation. For example, and as illustrated in Figures 1 to 3, these may be circular with different diameters. This difference between the input connector 5 and the output connector 7 acts as a polarizer and thus avoids erroneous connections with the rest of the thermal management circuit, in particular with the expansion valve.
    [0011] The base 3 may further include an enlargement 34. This enlargement 34 more particularly comprises a fastening means 36 of said connection device 1 to a wall 112 of the battery pack protection box 100 or of the battery pack 100. 34 is then joined to the inner face of the wall 112 of the protective box while the base 3 passes through said wall 112 to allow connection with the rest of the thermal management circuit. To ensure a good seal of the assembly, the enlargement 34 comprises, on its circumference, a housing 38 for placing a seal. Said seal is then placed between said widening 34 and the wall 112 of the protective box. Thus, it is clear that because of its particular conformation, the connection and distribution device according to the invention allows increased adaptability to different types of battery packs or battery packs.
