FIELD: electrical engineering.
SUBSTANCE: according to the invention, the electric power accumulation device includes at least one electric power accumulation element having the first end equipped with the first electrode, and the second end equipped with the second electrode; electric bus of the first electrode, which is located on the side of the first end and is connected to the first electrode; and electric bus of the second electrode, which is located on the side of the second end and is connected to the second electrode. Electric bus of the first electrode is equipped with a connecting line connected to the first electrode. Electric bus of the first electrode and the electric bus of the second electrode are connected to each other by means of an ultrasonic connection. Connection section between the electric bus of the first electrode and the electric bus of the second electrode is located in a position which is closer to the second end than to the first end.
EFFECT: technical result consists in improvement of reliability of power accumulation device.
