PURPOSE: Provided is a battery pack, in which a sensor for monitoring a temperature of the battery cell and a controller for controlling an internal temperature of the battery pack are positioned. CONSTITUTION: The battery pack comprises a battery cell(100) which is charged with constant current in constant-current charging mode; a sensor(110) for monitoring a temperature of the battery cell; a controller(120) which switches off when temperature monitored by the sensor exceeds baseline, and prevents an overheating of the battery; and a control circuit(130) for constantly maintaining a voltage output from the battery cell, and measuring a voltage of the battery cell to inform a remaining usable period of the battery to user. |
