Abstract: A method for detecting a fault state of at least one battery cell of a battery having multiple battery cells. A cell voltage of a respective battery cell of the multiple battery cells is registered at a measurement time and a comparison value is determined as a function of at least one of the cell voltages and is compared to a provided first reference value. The fault state is detected as a function of a result of the comparison. A scatter value is determined, which represents a scatter of at least part of the cell voltages registered at the specific measurement time, and the fault state is determined as a function of the scatter value.

Abstract: A method for detecting an imminent overheating of at least one battery cell of a battery, preferably for a motor vehicle. The imminent overheating is detected as a function of at least one determined first variable relating to the at least one battery cell. A temperature gradient over time of a temperature sensed in a predetermined proximity to the at least one battery cell and/or a voltage of the at least one battery cell is determined as the at least one first variable.

Abstract: A guiding system for a sliding door, especially a motor vehicle, comprising a sliding rail (5) with an upper cover (6) and a lower edge (7) arranged opposite the upper cover (6), and a roller element (101) which is guided in the sliding rail (5) and comprises a roller element housing (102) is presented. Three rollers (103, 104) are rotatably fixed to the roller element housing (102), two rollers (103) extending along the upper cover (6) of the sliding rail (5) and the third roller (104) extending along the lower edge (7). The invention creates one such guiding system in such a way that there is no play, it operates quietly, and has a taut system characteristic. To this end, a spring element (109) is fixed to the roller element housing (102), said spring element pressing on of the first two roller (103) and the third roller (104) against the sliding rail (5).
