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.

First claim

What is claimed is:

1. 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…
