Patent ID: 7642751

Claim:
A battery pack including a battery cell and a protection circuit module, in which the protection circuit module is electrically connected to the battery cell and includes a protection circuit for controlling overcharge, overdischarge, and overcurrent of a battery, wherein the protection circuit module comprises: a pair of connecting members, which are mounted to a rectangular lower end of the protection circuit module and electrically connected to the protection circuit; and a pair of coupling members coupled to the corresponding connecting members while plate-shaped electrode terminals of the battery cell are interposed between the connecting members and the coupling members, wherein the connecting members are detachably coupled to the coupling members in such a way that the coupling members surround the corresponding connecting members, with the electrode terminal interposed in-between, and the connecting members and the coupling members have coupling parts, which are constructed in a complementary structure to increase the coupling force between the connecting members and the coupling members.
