  • Publication number: 20250007132
    Abstract: A device for electrically contacting a terminal pole (2) of a battery cell (3) comprises a fuse (1) that is electrically connected to the terminal pole (2) and to a contact point (4) spaced from the terminal pole (2) in a main direction (5). The electrical connection to the terminal pole is reliably disconnected at a predetermined overcurrent, regardless of any operating conditions or faults. The fuse (1), which is connected to the terminal pole (2) via a connecting conductor (6) and is spaced from the terminal pole (2) in the main direction (5) via a spacer, runs in an insulation area (7) which is separated in the main direction (5) by an insulating element (8) from a hazard area (9) that adjoins the connecting pole (2) and through which the connecting conductor (6) passes at least in sections.

  • 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).

  • Publication number: 20240030515
    Abstract: A temperature-control device for individual battery cells (1) combined to form a module has a main body (2) that, in order to circumferentially surround the battery cells (1), has passage openings (4) situated opposite one another in pairs in relation to a respective joining axis (3) and that forms a flow channel (5) for a temperature-control fluid. The flow channel (5) runs transversely with respect to the joining axes (3). In order to make a reduced temperature spread possible within a battery module whilst simultaneously providing good homogeneous temperature control of the individual battery cells of the battery module, the flow channel (5) is divided into at least two chambers (7, 8) by a membrane (6) that runs transversely with respect to the joining axes (3) and that has passage openings (4) for the battery cells (1).

  • Publication number: 20230411733
    Abstract: A battery cell has electrodes (2) surrounded by a cell casing (1), with an end portion (3) of the cell casing (1) forming a circular cylinder. The battery cell in particular when used in a fluid-temperature-controlled battery module with good temperature-control properties, has reliably sealed storage and the energy density of circular-cylindrical battery cells is thus exceeded. A receiving portion (4) connects, at the circular-cylindrical end portion (3), to lateral surfaces that are parallel opposite one another in pairs.

  • 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.

  • Publication number: 20230008601
    Abstract: A device for breaking the electrical connection to a battery cell (1) in the event of outgassing has the cell pole (3) on the outgassing valve side connected to an electrical contact point (5) at a connection point (4) via a connecting lead (2) which forms a fuse. The device, requiring few components and having a compact design, enables a reliable electrical and thermal protection of neighboring cells of an outgassing battery cell against overloading and prevents the spread of a thermal runaway. The device provides a spacer (6) between the connection point (4) and the contact point (5) that electrically isolates the connection point (4) from the contact point (5) in the event of outgassing and that retains the cell pole (3).

  • Publication number: 20220181717
    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),In order not only to reduce the risk of thermal damage to individual battery cells (4) during peak loads, but also to prevent the propagation of a chain reaction in the event of a thermal runaway fault, it is proposed that, for each battery cell (4), a burst protection sleeve (7, 8), which surrounds the battery cell (4) circumferentially with a clearance by forming an air gap (10), is mounted upstream and downstream of the flow channel (6) in the direction of the joining axis (2), wherein the flow channel (6) extends over a height of 28-60% of the battery cell (4) and each burst protection sleeve (7, 8) extends separately over a height of 20-36% of the bat
