1. A plurality of battery cells (20) comprising
a first battery cell (20) having
at least one galvanic cell, and
a first cell housing element (12) and a second cell housing element (16),
wherein the first and second cell housing elements (12, 16) jointly enclose the galvanic cell,
wherein the first cell housing element (12) comprises on an inner face (13) thereof inner depressions (30) that are outer protrusions (30) on an outer face (14) of the first cell housing element (12), said outer face lying directly opposite the inner face (13), wherein the first battery cell (20) further comprises compensating elements,
wherein the compensating elements (50, 65-69) are configured in such a complementary manner with respect to the inner depressions (30) and are arranged in such a manner in the inner depressions (30) that the compensating elements (50, 65-69) together with the inner depressions (30) form a flat inner surface (13) of the first cell housing element (12), and
a second battery cell (20) having on an outer face thereof outer depressions (40) that are inner protrusions on an inner face of the second battery cell (20), the outer face of the second battery cell directly opposite the inner face of the second battery cell, wherein the outer protrusions (30) of the first battery cell (20) are nestled in the outer depressions (40) of the second battery cell (20), and wherein the first and second battery cells (20) are electrically connected to one another via an interlocking of the outer protrusions (30) and the outer depressions (40).
