1. A battery module having a multiplicity of battery cells, wherein battery cells (14) of the battery module (10) are in thermally conductive contact with an electrical resistive heating element (30) that comprises an electrical resistive heating wire (31), characterized in that a first area (32a) of the electrical resistive heating element (30) comprises an electrical resistive heating wire (31) with a first cross section, which is in thermally conductive contact with a first outer surface region of the battery cells (14), and in that a second area (32b) of the electrical resistive heating element (30), which has an electrical resistive heating wire (31) with a second cross section different from the first cross section, is in thermally conductive contact with a second outer surface region of the battery cells (14).
