Description
Technical Field
The invention relates to an assembly and a method for the electrical contacting of a cell module of a battery by means of at least one electrical connector. The invention further relates to a battery having such an assembly.
Background
Document US 2011/0104566 a1 describes a rechargeable electrical storage element in the form of a secondary cell (referred to herein as a secondary battery) with an electrode assembly arranged in a housing and with bus plates (strommsalmeplotte) at the respective ends of the electrode assembly, which form the positive and negative electrodes. Outside the housing, the positive and negative electrodes merge into a rivet (or rivet, i.e., Niet) which is joined to a busbar by friction stir welding (Reibr ü hrschwei beta either) or by laser beam welding. Friction stir welding is used to join mating parts made of different materials, for example aluminum and copper, for which laser beam welding is used to join mating parts made of a uniform material, for example aluminum or copper. Document DE 102009047490 a1 describes a method for producing an electrically conductive connection between a transverse connector and a contact pin at a battery cell of a battery pack. It is also proposed here to connect the joint partners with the same type of material (aluminum or copper) to one another by laser beam welding. In order to connect the mating parts made of different materials to one another also according to the above-described material-fit joining method, it is proposed that the cross connector be provided with a coating made of the material of the contact pins.
It is generally known that the individual battery cells are combined to form what is known as a battery module in a module housing and are electrically connected to one another by means of bus bars (also referred to as connectors), as a result of which negative and positive electrode ports of the battery module are produced. By the electrical connection of a large number of such battery modules, HV batteries (HV = high voltage) can be manufactured which can be used, for example, as traction batteries for electric vehicles. The electrical connection between the battery modules described above is obtained in the case of the application of electrical connectors, which are themselves connected with the battery modules in the case of the relaying of plug contacts or adapter members consisting of copper. This clearly results in a permanently stable electrical connection between the battery modules, which is however relatively costly, in particular also in view of the use of different materials, such as aluminum and copper, for the construction of the electrode ports of the battery modules. The invention described subsequently is set forth herein.
Disclosure of Invention
The aim of the invention is to create an assembly for the electrical contacting of a cell module of a battery, which is less expensive while ensuring a permanently stable electrical connection. It is also an object of the invention to provide a battery with such an assembly for use. In addition, the object of the invention is to specify a suitable method for electrically contacting the cell modules of a battery.
Starting from an assembly for the electrical contacting of a battery module of a battery by means of at least one electrical connector, which is constructed in one piece and has a contact section for the contacting of a negative electrode port of the battery module at one end and a contact section for the contacting of a positive electrode port of another battery module at the other end, wherein the electrode ports of the cell modules are composed of copper, of a copper alloy, of aluminum or of an aluminum alloy, the proposed object is achieved in that the electrical connector composed of aluminum or an aluminum alloy and the contact sections thereof are each connected in a material-fit manner to the associated electrode port of the battery module.
By this measure, a permanently stable electrical connection between the electrical connector and the electrode port of the battery module is created with little material and cost expenditure, which also makes a completely automated joining process possible.
The invention has a number of preferred developments or embodiments.
It is provided in this way that the contact sections of the connectors contacting the electrode ports of the battery modules made of copper or copper alloys additionally have a coating made of copper or copper alloys. This has the advantage that the engagement points of the engagement partners consist of the same type of material, i.e. aluminum or copper, as a result of which a particularly tight engagement connection is produced. Preferably, the above-mentioned coating is applied to the contact sections concerned by cladding or electroplating. Cladding is understood by those skilled in the art as mechanically applying a metal cladding (here copper or copper alloy) to a base material (here aluminum or aluminum alloy). In contrast, when applying a metal layer galvanically to the above-mentioned base material in an electrolytic cell, the metal ions are detached from the so-called load electrode by means of an electric current and are deposited on the workpiece serving as a cathode. It is also preferred that the contact sections of the connectors are each connected to an associated electrode port of the battery module by laser beam welding. In laser beam welding (also referred to as laser welding), energy input for welding is achieved via a laser beam which, at higher welding speeds, makes possible a long and narrow weld seam shape with minimal thermal warping of the joining partners. Each contact section is provided with at least one material-fit type of engagement site. Preferably, however, two engagement points of the material-fitting type are provided which are arranged in a distributed and spaced-apart manner. In order to achieve a non-material-fitting joining connection, for example in the case of a repair or also as an emergency solution, the respective contact section can be provided with a first through-bore which is preferably arranged between the two aforementioned joining points which are arranged separately and at a distance from one another. The first through-bore corresponds here to the second through-bore in the associated electrode port and in the module housing of the battery module, which carries or supports the electrode port. The second through-bore can then, for example, end in a receiving groove formed in the housing section described above for an insertion nut which has or can have a fastening screw which passes through the first through-bore and the second through-bore. Alternatively, the second through-bore can also have or be designed as an internal thread of a fastening screw for the through-bores, in order to produce a joint connection by means of a mechanical fastening element. The invention is not, however, limited to the repair or emergency solutions mentioned, but also includes a connection by means of a fastening screw, which is provided in addition to a material-fit connection, in order to be able to releasably contact an electrical measuring device, for example.
The invention also relates to a battery with an assembly of the type described above.
The method according to the invention for the electrical contacting of a battery module of a battery by means of an electrical connector, which is constructed in one piece and has a contact section for contacting a negative electrode port of the battery module at one end and a contact section for contacting a positive electrode port of another battery module at the other end, wherein the electrode ports of the battery module consist of copper, of a copper alloy, of aluminum or of an aluminum alloy, is distinguished in that, for the above-mentioned electrical contacting, in addition to an electrical connector consisting of only aluminum or an aluminum alloy, an electrical connector consisting of aluminum or an aluminum alloy is also provided for assembly, which electrical connector, in view of the fact that the electrode ports consisting of copper or a copper alloy have a coating consisting of copper or a copper alloy in the region of the associated contact section, is selected in such a way from the electrical connectors provided depending on the currently arranged material of the electrode ports of the battery module to be connected, such that a contact of the same type of material is achieved between the contact sections of the connector and the electrode ports of the respectively associated battery module, and any contact section of the connector is connected with the electrode port of the associated battery module, in particular by laser beam welding.
This has the advantage that, with the cost-effective use of aluminum as the base material for the base body of the electrical connector and the correspondingly minimized mass, rapid, if possible automated electrical contact between the connector and the electrode port of the battery module concerned is achieved by, in particular, laser beam welding. It is therefore possible to fittingly and electrically connect battery module materials with electrode ports composed of not only aluminum or an aluminum alloy but also copper or a copper alloy to each other according to preference while maintaining the above-described advantages.

Detailed Description
Fig. 1 shows first a lower housing 2 of a battery housing of a battery 3, which is equipped with a battery module 1, the battery 3 being, for example, an HV battery 3 which can be used as a traction battery for a vehicle, in particular a motor vehicle. Any battery module 1 is generally composed of two or more battery cells, which are united in a module housing 4 of the battery module 1 and electrically connected to one another (not drawn). Either battery module 1 has a negative electrode port 5 and a positive electrode port 6. The negative electrode port 5 of a battery module 1 and the positive electrode port 6 of another battery module 1 are electrically connectable to each other by means of a so-called electrical connector 7.
The electrical connector 7 is constructed according to this embodiment from a profile bar (profiletab) and is made in one piece from aluminum or an aluminum alloy. The electrical connector 7 has on both sides one contact section 8,9 each for the material-fitting connection thereof with the associated electrode port 5, 6. In the region between the contact sections 8,9 of either connector 7, there is an electrical insulation 10, which is preferably composed of plastic (see fig. 1-3).
The contact sections 8,9 are preferably connected to the respectively associated electrode ports 5,6 of the battery module 1 by laser beam welding. Fig. 2 shows the engaged connectors 7 in this respect, wherein a single engagement point 11 is provided in each case. In this case, the electrode ports 5,6 of the battery module 1 are also composed of aluminum or an aluminum alloy, so that a sufficiently strong joint connection between the joint partners can be ensured.
In practice, however, battery modules 1 are also constructed whose electrode ports 5,6 consist of copper or a copper alloy. Furthermore, battery modules 1 are also known which have two electrode ports 5,6 made of different materials from one another. In order to also take this into account, in addition to the electrical connector 7 consisting of aluminum or aluminum alloy alone, an electrical connector 7 is also provided whose base body, which consists of aluminum or aluminum alloy, has an undepicted coating of copper or copper alloy in the region of the associated contact sections 8,9 in view of the electrode ports 5,6 of the battery module 1 consisting of copper or copper alloy. As already mentioned above, the coating is preferably applied to the contact sections 8,9 of the connector 7 concerned by coating or electroplating.
The embodiment of the invention according to fig. 4 differs from that described above in that, on the one hand, two separate joining points 11a,11b are provided, which are arranged at a distance from one another. On the other hand, a central first through-bore 12 is visible in the contact sections 8,9 of the connector 7 between its two engagement points 11a,11 b. The first through-bore 12 corresponds to a second through-bore, which is not drawn, in the associated electrode port 5,6 (the current positive electrode port 6) and in the housing section of the module housing 4 of the battery module 1 supporting the aforementioned electrode port 6. The second through-bore ends in a receptacle 13 for an insertion nut, not shown, in the housing section described above.
Given that a replacement of the battery module 1 is intended or required, for example in the case of a repair or as an emergency solution, it is possible according to fig. 5 to electrically conductively connect a new connector 7 to the electrode port 5,6 concerned by means of a mechanical fastening element (fastening screw which is not currently represented). In this case, the "old" connector 7 is first separated in the region of its contact sections 8,9, so that only the contact sections remain at the associated electrode ports 5, 6. Next to this, the "new" connector 7 is placed with its contact sections 8',9' onto the original contact sections 8,9 and finally screwed with the respective electrode port 5,6 by means of the fastening screw described above. The fastening screws in this case penetrate a first through bore 12 and a corresponding second through bore of the contact sections 8,8',9,9' and are screwed into in each case one insert nut (not drawn). Alternatively, the fastening screw can also be accommodated by a second through bore configured as a threaded bore. The insertion nut described above is therefore optional (not drawn).
The invention is not, however, limited to the repair or emergency solutions mentioned, but also includes a connection by means of a fastening screw provided in addition to a material-fitting connection in order to be able to releasably contact an electrical measuring device (not represented) for example.
