Because the matrices are introduced into the at least one element of the battery, electrical contact can be made with the battery cells by means of clinching on one side. By clinching, respective cell arresters can be positively connected to the element of the battery having the die. In particular, the at least one cell arrester can be stamped into the respective die provided by the element by means of a stamp, as a result of which the at least one cell arrester is interspersed with the element having the die.
- the tool comprises several stamps, by means of which a battery block comprising several battery cells of the battery is penetrated at several, in particular at a plurality of points at the same time, in particular with an electrically conductive material in order to electrically connect the battery cells of the battery block to one another.
- This tool which has a plurality of punches, can in particular be designed to be insulated against a short circuit.
- the method thus enables particularly rapid electrical contacting of a particularly large number of battery cells of a battery block of a battery, as a result of which the battery can be made available particularly quickly.
- the battery is, in particular, a vehicle battery, the individual battery cells of which are to be connected to the respective cell arresters via clinching joints.
- the matrices are placed in a cell frame or a cell block as elements of the battery, so that the tool can clinch directly into the battery block using the one-sided accessibility.
- a Mehrfachstem pel tool comes for use, which can execute all clinch points arranged on the same side of the battery block in one cycle, whereby a particularly short cycle time can be achieved.
- electrical insulation can be arranged on the battery block by means of clinching.
- the invention further relates to a device for providing a battery for an electrically operated motor vehicle, with a receiving device, by means of which a plurality of battery cells arranged next to one another to form a battery block can be received.
- the device comprises a stamping device, by means of which the battery cells can be electrically connected to one another at several mutually different points at the same time by means of clinching via at least one further component of the battery, with at least one element of the battery providing respective matrices for clinching.
- a cell frame or a cell block of the battery can have the plurality of matrices, via which the battery cells can be electrically contacted by means of the clinch connections and thus by means of clinching.
- the stamping device is set up, in particular, to connect all of the dies arranged on the same side of the battery block simultaneously to the at least one further component by clinching.
- FIG. 1 shows a process diagram for clinching a battery with one-sided accessibility, with a first cell arrester and a second cell arrester being connected to a cell frame or a cell block made of plastic via the clinching connection in order to make electrical contact with a plurality of battery cells of the battery;
- FIG. 2 shows a process scheme for clinching multiple battery cells simultaneously by means of a tool in a single cycle.
- FIG. 1 shows a method for clinching a first cell arrester as a first component 10 and a second cell arrester as a second component 12 with a battery cell 14 of a battery block 16 of a battery.
- the respective battery cells 14 can be electrically contacted with the components 10, 12 by clinching.
- Clinching which can also be referred to as clinching, is an efficient solution for connecting the components 10, 12 to the battery block 16 in a form-fitting and partially cohesive manner in a continuous forming process.
- the clinching enables several layers of respective components 10, 12 to be reliably connected to one another. Since clinching takes place without the supply of heat, distortion in a workpiece to be clinched can at least essentially be avoided.
- thermally sensitive materials can be arranged during clinching in the vicinity of a point at which clinching is carried out.
- the battery block 16 is part of a vehicle battery of a motor vehicle.
- the battery can be used to provide electrical energy for driving the motor vehicle.
- the first component 10 is stacked on the second component 12 in a joining direction 18 and the components 10, 12 are arranged on the battery cell 14 so as to cover a matrix 20 provided by the battery cell 14 in the joining direction 18 .
- at least one punch 24 is then placed in the joining direction 18 on one of the components 10, 12 by means of a tool 22 and the components 10, 12 are pressed onto the die 20 provided by the battery cell 14.
- the first component 10 is a first cell arrester, which in the present case is made of copper or aluminum.
- the second component 12 is a second cell arrester, which in the present case is made of aluminum or copper.
- the cell arresters can be electrically contacted with the battery cell 14 by clinching.
- the contacted battery cell 14 can be connected to further battery cells 14 via the electrical contacting of the respective battery cell 14, in particular in a series connection or in a parallel connection.
- a plurality of battery cells 14 are arranged next to one another, in particular stacked, to form the battery block 16.
- the matrices 20 are introduced into the respective cell frames of the battery cells 14.
- the matrices 20 can be introduced into the cell frames before the battery cells 14 are stacked to form the battery block 16 or afterwards.
- the cell frame is advantageously a plastic component.
- the matrices 20 can be molded into these plastic components during the manufacture of the plastic components, for example during an injection molding process.
- the first component 10 and the second component 12 are stacked on top of one another in the joining direction 18 and placed on the battery block 16, as a result of which the components 10, 12 cover a plurality of matrices 20 in the joining direction 18.
- the components 10, 12 cover all the matrices 20 arranged on the same side of the battery block 16.
- a tool 22 which in the present case comprises a stamp device 26 with a plurality of stamps 24, all the matrices 20 arranged on the same side of the battery block 16 are simultaneous Can be connected to the components 10, 12 via clinching.
