PURPOSE: A battery pack is provided to lower the output voltage of the battery pack to the level of a battery module when the insulation of the battery pack is destroyed due to an impact or flooding, thereby avoiding possible danger such as fire or electric shock. CONSTITUTION: A battery pack comprises: at least one battery module(100) which is composed of multiple battery cells(10) arranged in one direction; multiple first fuses(20) formed between the battery modules; a battery control unit(200) connected to the multiple first fuses; and at least one sensor connected to the battery control unit. The battery control unit delivers a signal received from the sensor to the multiple first fuses. The first fuse includes a power blocking part formed in one region of connecting members that connect the battery modules and a case covering the power blocking part. |
