NOVELTY - The accumulator assembly (10) comprises electrical energy accumulator elements (12) that are superimposed along a stacking axis and include connection electrodes, an electroconductive strut (22) axially arranged between the connection electrodes and electrically connected to the elements, an elastically deformable connector plug mounted inside a recess (30) of the strut and connected to an electric cable (31) for measuring voltage, a unit for providing protection against short-circuit, electrically conducting spacers, and a connector.    USE - The accumulator assembly is useful for a battery of an electric vehicle or a hybrid vehicle.    ADVANTAGE - The accumulator assembly can be economically, easily and rapidly manufactured with reduced size and reliably operated for long time without degrading its performance.    DETAILED DESCRIPTION - The accumulator assembly (10) comprises electrical energy accumulator elements (12) that are superimposed along a stacking axis and include connection electrodes, an electroconductive strut (22) axially arranged between the connection electrodes and electrically connected to the elements, an elastically deformable connector plug mounted inside a recess (30) of the strut and connected to an electric cable (31) for measuring voltage, a unit for providing protection against short-circuit, electrically conducting spacers, a connector on which an end of the electric cable connected with the connector plug is fixed, and insulator spacers. The protection unit is electrically connected with the connector plug, is mounted on the electric cable, and comprises a fuse. The conductor spacers comprise a base, and a heel that extends in projection with the base and is formed in the recess. The recess transversely extends with respect to the stacking axis of the accumulator elements in parallel to a front side of the base. The electrically conducting spacers are axially disposed between the connection electrodes and connectors. The accumulator elements have positive and negative connection electrodes along the stacking axis so that a positive electrode element of the accumulator element is axially disposed adjacent to the negative electrode of the adjacent accumulator element. The insulator and conductor spacers are arranged for connecting the accumulator elements in series.
