Abstract
Disclosed herein is a protection circuit module (PCM) including a protection circuit for controlling overcharge, overdischarge, and overcurrent of a battery. The protection circuit module includes a pair of connecting members, which are mounted to a rectangular lower end of the PCM and electrically connected to a protection circuit, and a pair of coupling members coupled to the corresponding connecting members while plate-shaped electrode terminals of a battery cell are interposed between the connecting members and the coupling members, and a battery pack including the protection circuit module, which is electrically connected to a battery cell. According to the present invention, a welding or soldering process, which requires a large amount of time and a high degree of technical skill to manufacture a battery pack, is not necessary, the coupling force between the battery cell and the PCM is increased, and the inner space of the battery pack is maximally utilized.
