摘要： A system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor is disclosed. The system for managing a vehicle battery as disclosed includes a controller that measures a voltage of each of a plurality of battery cells in a vehicle battery when a voltage applied to the vehicle battery is constant, and determines whether the plurality of battery cells is abnormal based on a deviation between the measured voltages of the plurality of battery cells.

摘要： The present disclosure relates to a battery cell. The battery cell includes: an electrode assembly; a pouch which wraps around the electrode assembly; an electrode tab extended from the electrode assembly; a lead tab attached to the electrode tab; and a current interrupt device which is configured to block reconnection of the lead tab and the electrode tab when the pouch is shrunk to return to an original position after being expanded, while blocking current flow by separating the lead tab and the electrode tab through the expansion of the pouch, when abnormal situation of battery cell occurs.

摘要： A pouch battery having improved overcharging safety includes a CID interrupting an electrical connection between an electrode assembly and a lead tab when the pouch is expanded. When the pouch is expanded, the CID discharges gas generated inside the pouch to the outside, and at the time of overcharging a secondary battery, the CID interrupts a flow of current introduced into the secondary battery and discharges the gas generated due to the overcharging to the outside of the pouch, thereby reducing an ignition risk and improving the overcharging safety.
