DISPOSITIF D'ACCUMULATION D'ENERGIE ET SUPPORT D'ELEMENT POUR UN DISPOSITIF D'ACCUMULATION D'ENERGIE

摘要

The invention relates to an energy storage device (5) in which in each case a plurality of energy storage cells (4) between at least two packing levels (1, 2, 3) between a first cell holder (10, 110) and a second cell holder (14) of the respective packing level wherein at least one of the energy storage cells of one of the packaging planes is electrically connected to a cell stack by means of at least one contact element (20) disposed between the mutually facing cell holders of adjacent packaging planes, with a corresponding energy storage cell of at least one adjacent packaging plane, and wherein the energy storage device above and / or underneath the cell stacks has a closure plate (16, 18), and wherein the first cell holder and the second cell holder of the at least two packing planes each have a plurality of continuous mounting recesses (26, 28), wherein through the mounting recesses of these cell holders through each u by means of which at least the energy storage cells of the at least one cell stack (a, b, c) are clamped together, and wherein at least a part of the attachment recesses are located farther from a nearest outer boundary of the energy storage device than at least one energy storage cell , and wherein a tensile force of the fastening means is at least indirectly applied to the cell stacks by means of the upper and / or lower end plate, to which the fastening means are fixed, and a cell holder (10, 100).
