Abstract: The invention relates to a battery cell (2), comprising a negative terminal (15), a positive terminal (16) and a fast discharging device (70), whereat the fast discharging device (70) comprises a first busbar (71) that is electrically connected to the negative terminal (15), a second busbar (72) that is electrically connected to the positive terminal (16) and an activation unit (75) that is connected to the first busbar (71) and to the second busbar (72). At least one connection element (91, 92) is arranged between at least one busbar (71, 72) and at least one terminal (15, 16), whereat the connection element (91, 92) is electrically conductive and a melting temperature of the connection element (91, 92) is lower than a melting temperature of the busbar (71, 72) and lower than a melting temperature of the terminal (15, 16). The invention also relates to a method for producing a corresponding battery cell (2).

Abstract: A clutch sensor system includes a clutch part that is rotatable about and axially displaceable along an axis of rotation, and a sensor device having at least one sensor element configured to detect a rotary movement parameter of the clutch part. A circumferential transmitter structure is disposed on a circumference of the clutch part, and has a first sub-structure and at least one second sub-structure that follow each other in alternating fashion in a circumferential direction. The sub-structures are separated by structure transitions that move past a detection area of the sensor element as the clutch part rotates, whereby the sensor device generates a sensor signal that includes information about the rotary movement parameter. A circumferential distance between successive structure transitions depends on an axial displacement of the clutch part, such that the sensor signal also includes information about the axial displacement position of the clutch part.

Abstract: A device for detecting a rotational angle of a rotatable part, e.g., a steering wheel, includes at least one magnet, at least one sensor which detects the magnetic field of the magnet, at least one housing in which the sensor and/or the magnet is/are movably situated relative to one another, and at least one printed circuit board which is contacted in an electrically conductive manner by at least one connecting element of the sensor. The printed circuit board has at least one interface or a connector plug from which the output signal of the sensor or an output signal derived therefrom is relayed to an evaluation unit which ascertains the absolute position of the rotational angle as a function of the output signal.
