CIRCUIT BOARD FOR SECONDARY BATTERY AND BATTERY PACK INCLUDING THE SAME

摘要

Disclosed is a circuit board for a secondary battery, which ensures an improved safety according to a temperature of the secondary battery, and a battery pack including the circuit board. The circuit board for a secondary battery, which is connected to at least one of a cathode tab and an anode tab of the secondary battery, includes a tab coupling portion connected to the cathode tab or the anode tab, a charging/discharging path connected to the tab coupling portion to give a path through which a charging current or a discharging current of the secondary battery flows, the charging/discharging path having at least one path cutting portion formed therein, one pair of conductive plates respectively attached to both ends of the path cutting portion, the conductive plates being at least partially bent, and a current interruption module having both ends respectively connected to the one pair of conductive plates, the current interruption module sensing a temperature of the secondary battery and interrupting a current according to the sensed temperature.
