Abstract
A battery pack is constructed with at least two battery cells that are arranged in parallel to each other and provided with surfaces facing each other, and a spacer structure interposed between the facing surfaces of the battery cells. A through-hole is formed in an interior portion of the spacer structure and corresponds to a portion where thicknesses of the battery cells are increased when the battery cells are swollen. Therefore, the facing battery cells do not interfere with each other even if the thickness of the battery cell is changed due to swelling of the middle portion thereof when the battery cells are repeatedly charged/discharged in the case where at least two battery cells are included.
Claims19
A battery pack, comprising:
- at least two battery cells that are arranged in parallel to each other and provided with surfaces facing each other;
- and
- a spacer structure interposed between the facing surfaces of the battery cells.
A battery pack, comprising:
- at least two battery cells arranged in parallel to each other and provided with surfaces facing each other;
- and
- a spacer structure interposed between the facing surfaces of the battery cells and comprising a through-hole that forms a void in an interior region of the spacer structure, wherein the void is formed to correspond to portions of the battery cells where thicknesses of the battery cells increase when the battery cells are swollen.
A battery pack, comprising:
- at least two battery cells arranged in parallel to each other and provided with surfaces facing each other, with the facing surfaces of the battery cells being roughly rectangular;
- and
- a spacer structure interposed between the facing surfaces of the battery cells, with the spacer structure being formed along at least one pair of opposite sides of the facing surfaces of the battery cells.
