The present invention relates to a battery pack which can sequentially connect multiple battery cells and a monitoring wire upon a voltage by forming length of a pin of a connector differently upon voltages of the multiple battery cells. The battery pack according to the present invention comprises multiple battery cells; a monitoring part having one side connected to each of the multiple battery cells, and including a B+ high current line, a B- high current line, and at least one monitoring line; a connector connected to the other side of the monitoring part, and including multiple connector pins; and a protection circuit module including a connector storage part storing the connector, wherein the multiple connector pins are formed in different lengths. According to the configuration, defect rate of the protection circuit module of such a battery management system (BMS) can be reduced. |
