FIELD: electricity.
SUBSTANCE: invention is related to the accumulator battery design. In order to attain the specified result an element unit of the accumulator battery includes a variety of subunits. Each subunit includes a heat radiator as well as the first and second frames placed at the opposite sides of the heat radiator. The subunits are stacked to for a variety of cells for elements whereto an element of the accumulator battery is placed. An element unit of the accumulator battery includes additionally a variety of tension pins to fix together the variety of subunits. The first frame is made with a variety of through holes, while the second frame is made with a variety of protrusions, which pass through the holes. The frames are united so that each protrusion is placed at least partially to the respective through hole. Inner surfaces of the respective protrusions and through holes of the frame stack form the passage for one tension pin.
EFFECT: improving durability and increasing service life.
