  • Patent number: 12100854
    Abstract: A device is described for making independent contact with two battery cells, having a basic body comprising a through-opening (6). To enable not only an easier, modular assembly process, but also a quick replacement of individual battery cells, it is suggested that the basic body (1) comprises two receiving bodies (2,3) positioned opposite to the through-opening (6) for circumferential taking hold of one end portion each of the battery cells inserted in the receiving bodies (2,3) in a joining direction, wherein a contact spring (7) is inserted in a guide corridor (9) of the first receiving body (2) which leads into the through-opening (6) for bonded connection of the contact spring (7) with the battery cell inserted in the second receiving body (3), and that the contact spring (7) forms contact tongues (8) for releasable connection of the battery cell inserted in the first receiving body (2).

  • Patent number: 12095064
    Abstract: The invention relates to a battery module having with a main body (1) for accommodating individual battery cells (4) arranged in parallel with respect to a joining axis (2), which main body forms a flow channel (6) extending transversely to the joining axis (2) for a temperature-control fluid flowing directly against the cell shells of the battery cells (4).

  • Patent number: 12087958
    Abstract: The invention relates to a device with a carrier (3) having an opening (1) for receiving a battery cell (2) on the casing side, which carrier (3) has a measuring channel (5) extending between a carrier outer wall (4) and the opening (1) for a measuring head (6) which has a locking device for a measuring position set against the battery cell casing (7). In order to design a device of the type described at the beginning in such a way that a regulation adapted to the inhomogeneous distribution of the state variables within a battery module and within a battery cell is made possible and, at the same time, an industrial production of battery modules, in particular their assembly, is favored, it is proposed that the measuring head (6) has a galvanic contact point (12) of a voltage sensor, which contact point (12), in the measuring position, rests against the battery cell casing (7) which forms an electrical pole.

  • Patent number: 11677107
    Abstract: A temperature control device for individual battery cells (2) assembled to form a module (1), having a base body (3) which, for the purpose of circumferentially enclosing the battery cells (2), comprises two opposing sealing elements (4, 5) having passage openings (6) located opposite one another in pairs with respect to a respective joining axis, and which base body (3) forms a flow channel extending transversely to the joining axes for a temperature control fluid is described.
