Abstract
A battery pack is disclosed. The battery pack includes at least two battery cells to provide a high capacity battery pack. The battery pack includes a single PCM assembly controlling at least two battery cells to decrease inferiority due to overcharge and overdischarge. Since a connector tab electrically connecting at least two battery cells to a single PCM assembly is provided, contacts are not separated during the swelling of the battery cells to prevent contact inferiority. A top case and a bottom case are provided to be coupled with at least two battery cells to maintain a secure coupling between the at least two battery cells.
Claims32
A battery assembly comprising:
- a first battery cell;
- a second battery cell wherein the first and second battery cells are mounted adjacent each other;
- a protection circuit module that is electrically coupled to the first and second battery cells;
- and
- at least one connector tab consisting of a protection circuit mounting portion having an upper surface and a lower surface and a first and second battery cell mounting portions coupled to the lower surface of the protection circuit mounting portion via first and second connection portions that extend outward from the lower surface of the protection circuit mounting portion, wherein the at least one connector tab has a bridge shape in which the protection circuit mounting portions, the first and second connection portions, and the first and second battery cell mounting portions are integrally formed with each other, wherein the protection circuit module is coupled to the upper surface of the protection circuit mounting portion and the first and second battery cells are coupled to the first and second battery cell mounting portions and wherein the protection circuit mounting portion is displaced in a first direction from the first and second battery cell mounting portions.
A method of assembling a battery pack, the method comprising:
- positioning a first and a second battery cell adjacent each other;
- and
- electrically coupling the first and second battery cells together and to a protection circuit module with at least one connector tab, wherein the at least one connector tab consists of a protection circuit mounting portion having an upper surface and a lower surface and a first and second battery cell mounting portions coupled to the lower surface of the protection circuit mounting portion via first and second connection portions that extend outward from the lower surface of the protection circuit mounting portion, wherein the at least one connector tab has a bridge shape in which the protection circuit mounting portions, the first and second connection portions, and the first and second battery cell mounting portions are integrally formed with each other, wherein the protection circuit module is coupled to the upper surface of the protection circuit mounting portion and the first and second battery cells are coupled to the first and second battery cell mounting portions and wherein the protection circuit mounting portion is displaced in a first direction from the first and second battery cell mounting portions, wherein the first and second battery cells and the protection circuit module are mounted to the at least one connector tab so that the protection circuit module is offset from the first and second battery cells in a first direction.
