BATTERY PACK CONTAINING PRINTED CIRCUIT BOARD EMPLOYED WITH CONDUCTIVE PATTERN

摘要

A battery pack is provided to ensure fast reaction speed by high current and to efficiently secure the safety of a battery by fusion cutting fused part in conducting high current due to conductive patterns formed with a fuse-cutting part with high resistance. A battery pack comprises a battery cell where an electrode assembly of a positive electrode/separation film/negative electrode structure is accommodated with electrolyte inside the battery case; and a protection circuit board(200) electrically connected to the battery cell. The conductive pattern(400) containing a fuse-cutting part(410) with high resistance is equipped at a connection part of a circuit on a printed circuit board. The fuse-cutting part cuts blocks current by being fuse-cut in conducting of high current.
