  • Publication number: 20240322292
    Abstract: A battery pack includes: a plurality of battery cells in a plurality of columns, the battery cells in each of the columns being located along a column direction, and the battery cells in the columns adjacent to each other being located along a zigzag pattern in a row direction while alternately shifted forward and rearward in the column direction; a plurality of cooling pieces, each of the cooling pieces being located between the battery cells in the columns adjacent to each other, and extending in a meander shape along an outer circumference of the battery cells in the columns adjacent to each other; and a bus bar on a terminal surface of the battery cells to electrically connect the battery cells to each other in rows adjacent to each other, the terminal surface being a surface on which different first and second electrodes are exposed.

  • Publication number: 20190267580
    Abstract: A battery pack includes: a case including a cell accommodation portion to accommodate a battery cell; and output terminals protruding upward from a first side of an upper portion of the case, and the output terminals protrude from first height-difference surfaces stepped downward from a first surface that is an uppermost surface of the first side of the case. The structure of the battery pack is improved such that the output terminals protruding outward may be effectively protected from impactive force, and the battery pack may be combined with other battery packs having substantially the same shape to flexibly cope with high-output, high-capacity demand.
