The subject matter of the invention is a battery module for a motor vehicle having a multiplicity of battery cells, each having a first pole and a second pole and a contact plate which extends in a transverse direction and in a longitudinal direction, wherein a first group of the battery cells are connected via their respective first pole, one after the other to a first side, extending in the longitudinal direction, of the contact plate, and a remaining second group of the battery cells are connected by their respective second pole, one after the other to a second side, extending in the longitudinal direction, of the contact plate, with the result that, by means of the contact plate the first group of the battery cells are connected via the first poles, and the second group of the battery cells are connected via the second poles, in parallel, and the first group of the battery cells and the second group of the battery cells are connected in series, and between adjacent first poles on the first side and/or between adjacent second poles on the second side, at least one cutout, extending in the transverse direction, is provided in the contact plate, with a length such that the ratio of the resistance of the contact plate in the extent in the longitudinal direction with respect to the resistance of the contact plate in the extent in the transverse direction is &#x2265;2.
