In order to specify a battery pack that can be simply produced, that provides sufficient heat dissipation during the assembly and during the operation of the battery pack (10) and a reliable electrical connection between the connection structures (14) and the connection contacts (33, 34) of the battery cells (11), and that copes with the failure of an individual battery cell (11), a battery pack (10) is specified, comprising: at least two battery cells (11), wherein each battery cell (11) has a positive and a negative electrical connection contact (33, 34), wherein a connection structure (14) is associated with at least the electrically positive connection contacts (33) or the electrically negative connection contacts (34) of the battery cells (11), wherein each battery cell (11) is connected to the connection structure (14) by means of at least one connection element (15, 51), wherein a cross-section of each connection element (15, 51) is matched to a predetermined maximum current of a battery cell (11), wherein the connection element (15, 51) is fastened to a side of the connection structure (14) facing the battery cells (11). Each connection structure (14) has a current strength that corresponds to the sum of the individual currents of each connected battery cell (11).
