Abstract: A method for charging and/or discharging an energy store with a current I0, wherein the energy store has at least one cell block having a number J of series-connected battery cells, at least some of the battery cells of which may have different efficiencies ?N, where 1?N?J, has the following method steps: determining the battery cell having the lowest efficiency ?min, and adjusting the efficiency ?N of all the other battery cells to this lowest efficiency ?min such that the adjusted efficiency ?N? of the battery cells is nN?=?min.

Abstract: The invention relates to a method for charging or discharging an energy store (2) with at least one cell block (20) consisting of multiple series-connected battery cells (3-7) by means of a series charging current (IO) flowing through all battery cells (3-7), wherein at least some of the battery cells (3-7) can have different capacitances (CN). In order to permit a reliable and quick charging of energy stores, the invention proposes measuring the capacitances (CN) of the N battery cells of the cell block at regular time intervals, and determining a maximum charging current for each battery cell based on the measured capacitances and a predefined C-factor (ratio of the maximum charging current IN;max to the capacitance CN) for each battery cell. With these maximum charging currents, the battery cells are then simultaneously charged during a charging time t (t?1/C) predefined by the C-factor.

Abstract: An automatic application system for self-adhesive protective film to vehicle bodies is disclosed. Two separate application stations are provided, of which one application station contains two pairs and the other contains one pair of stationary industrial robots arranged opposite each other for the joint handling and application of one piece of film in each case. As a result, it is possible to stick all the body parts simultaneously within the cycle time. In each case, one robot of a pair of robots contains in its application tool the holder for a supply roll and a cutting device, whereas the opposite application robot of this pair of robots carries a suction strip. For the accurate-contour perforation of a stretched-out piece of film, the latter is moved along a stationary perforating tool. Arranged close to the robot is a magazine for a plurality of supply rolls, from which the application robot automatically picks up a supply roll as required.

Abstract: In a method and apparatus for automatically applying self-adhesive protective sheeting to surface parts of vehicle bodies, a specific rectangular piece of protective sheeting in the form of stock roll is grasped on its non-adhesive side, using a robot-controlled tentering frame with suction legs, is drawn off and is cut off. Before the sheeting blank is laid on to the body, in the freely stretched-out state tear-off lines are perforated, preferably from the non-adhesive sheeting side, in the region of accessory parts by means of a perforating device guided along definite contour lines. Thereafter the protective sheeting, which is thus prepared and stretched out so as to be free of creases in the tentering frame, is lowered in the correct position onto the associated part by the handling robot and laid onto the surface part so as to be free of bubbles. The sheetings are subsequently pressed down in a brushing manner under an elastic brushing bar extending over the entire vehicle width.

Abstract: Device and method for changing film rolls, with apparatus for holding a first film roll in a working position in which film can be pulled off and separated from the film roll as desired, and holding a second film roll in a standby position. The second film roll can be moved from the standby position into the working position, with the first film roll being removable from the working position by moving the second film roll.
