Abstract

The invention relates to a battery (10) for an at least partially electrically driven motor vehicle, said battery comprising: at least one battery cell which is surrounded by a battery cell housing (12), the battery cell housing (12) having at least one wall (14) in which a reversibly sealable or irreversibly sealed degassing opening (16) is formed and through which at least one electrical contact (18) of the battery cell is guided; a printed circuit board (20) of a battery management system having at least one electronic component, said printed circuit board being arranged at a distance from the wall (14) having the degassing opening (16); a busbar (22) which is electrically conductively connected directly or indirectly to the contact (18), the busbar (22) being located between the wall (14) and the printed circuit board (20) at a distance from the degassing opening (16) and projecting completely beyond the degassing opening (20).
