1. A battery system, comprising:
a plurality of identically oriented battery cells, whose longitudinal axes are situated in parallel;
a first busbar; and
a second busbar, the first busbar and the second busbar being situated along the respective longitudinal axes on the same side of the battery cells, respective positive poles of the battery cells being connected to the first busbar using first bond connections, and respective negative poles of the battery cells being connected to the second busbar using second bond connections,
wherein the first and second busbars are on a side of the battery cells on which the positive poles are located, and each of the first bond connections is connected centrally to the positive poles, and each of the second bond connections is connected to a shoulder area of the battery cell, which forms the negative pole and encloses the positive pole, wherein a bonded wire of the second bond connections extends tangentially with respect to the battery cell,
wherein the cell holder includes one wall per battery cell of the battery cells, wherein the wall is configured to shield the positive pole and negative pole in an area between the first bond connection and the second bond connection.
