FIELD: power engineering.
SUBSTANCE: invention relates to an electric energy storage device. According to the invention, the electric energy storage device comprises a plurality of electric energy storage modules, each of which comprises module housing for electric energy storage, a plurality of electric energy storage elements arranged in the electric power storage module housing and external terminals of the positive and negative electrodes; housing of electric energy storage device, in which multiple modules for storage of electric energy is located and enclosed; plurality of bundles of wires connected to external terminals of positive and negative electrodes of electric energy storage modules; and a vibration damping material located in the spatial region between one surface of the housing of the electric power storage device and at least a bundle of wires from the plurality of wire bundles having the largest length extending in the direction of arrangement of the electric energy storage modules; wherein the wire bundle having the longest length extending in the direction of arrangement of the electric energy storage modules is shifted towards the side of the housing of the module for storing electric power with one surface of the housing of the device for storing electric energy through the vibration damping material.
EFFECT: preventing vibration of wire bundles during charge/discharge.
