Abstract: A power supply assembly includes: a casing having a base and at least two side walls; and a set of battery modules. Each of the modules includes a battery having two opposing ends, and two opposing flanges covering the ends. The modules are installed on the base in a plurality of rows of modules arranged in line with one another. The rows are arranged such that the flanges are aligned edge to edge. The aligned flanges are joined to the base of the casing so as to form rigid cross members inside the casing.

Abstract: Said method is used for detecting, in an electric storage battery (10) having a plurality of battery cells (1, 2, 3, 4), a self-discharge defect in a cell (1, 2, 3, 4), wherein: a charge balancing of the battery cells (1, 2, 3, 4) is at least partially carried out, a relaxation of the battery cells (1, 2, 3, 4) is performed, a charge balance during the balancing and relaxation (Σi) of said cell (i) is calculated for each battery cell (i), and any self-discharge defects of said cell (i) are detected for each battery cell (i) depending on the charge balance calculated for said cell (i) during the balancing and relaxation (Σi).
