1. A battery module having a multiplicity of battery cells that each have a battery cell housing, comprising a side surface that surrounds an inside of the cell, a bottom surface and a top surface, wherein the multiplicity of battery cells is arranged in the form of a battery cell stack, wherein the battery cells of the battery cell stack are positionally fixed in relation to one another by way of a tensioning belt wrapped around the battery cell stack, wherein the tensioning belt comprises an electrical resistive heating element, and wherein the side surfaces or the bottom surfaces of the battery cell housings collectively form a planar surface in physical contact with the electrical resistive heating element.
