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.
