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.

Abstract: A cooling device for battery cells assembled to form a module, having a base body and an insert which has receptacles for an end portion of the battery cells with recesses in the cell head. The insert together with the base body delimits a flow channel for a temperature control fluid A cooling device of this type permits operationally reliable accommodation of the battery cells with low manufacturing costs and high temperature control performance, without having to take manufacturing tolerances into account in advance. The receptacles form a fluid-tight membrane which encloses the end portion of the battery cells, which membrane is deformable for tolerance compensation of the individual battery cells and rests against the cell bottom when the flow channel is filled.

Abstract: A cooling device for battery cells (1, 2) assembled to form a module, having a base body (3) and an insert (4) which has receptacles (5) for an end portion (6) of the battery cells (1, 2) with the exception of the cell head (7), the insert (4) together with the base body (3) delimiting a flow channel (8) for a temperature control fluid, is described. In order to design a cooling device of this type in such a way as to permit operationally reliable accommodation of the battery cells with low manufacturing costs and high temperature control performance, without having to take manufacturing tolerances into account in advance, it is proposed that the receptacles (5) form a fluid-tight membrane (9) which encloses the end portion (6) of the battery cells (1, 2), which membrane (9) is designed to be deformable for tolerance compensation of the individual battery cells (1, 2) and is resting against the cell bottom (10) when the flow channel (8) is filled.
