Abstract: A battery pack with at least two electrochemical cells, lithium ion cells in particular, has each cell including a positive pole and a negative pole on the end face of the particular cell body, the poles of the cells being electrically connected in series and/or in parallel. A cell connector for electrically connecting the cells is provided on at least two cells, on the end face on the same side relative to their position in the battery pack, the cell connector connecting one pole of the connected cells and extending to a contact region of a circuit board; the cell bodies of the cells are positioned parallel to each other, and the end faces of the cell bodies are located in the same plane.

Abstract: The invention relates to a windshield wiper system with two wipers (1, 2) that travel in opposite directions and can each be driven by a separate motor (MFS, MBS), wherein a regulating unit (7) is provided for triggering the motors (MFS, MBS) separately from each other by means of control signals, wherein the regulating unit (7) triggers the motors (MFS, MBS) of the wipers (1, 2) in order to preset a time-dependent angular position of the wipers according to a trigonometric function ?(t).
