Abstract: The invention relates to an electric battery module (1) comprising a plurality of individual accumulators (2) in the form of cylindrical elements arranged in parallel rows mounted in a container (3). Said battery module (1) is characterized in that the container (3) comprises: for the one part, at least one support body (4) made of a rigid material that is a good heat conductor in the form of a profiled component having a comb-shaped cross section, forming elongate housings that are each configured to receive, in a non-fitted manner, a row of battery elements (2), and, for the other part, at least first mechanical wedging means (8) that prevent the movements of said elements (2) at least in the longitudinal direction of the housing that receives them and space apart said elements (2) from the two compartmentalizing walls (5) that define said housing.
