<p>The present invention relates to a control method and a battery pack to perform the protective operation by determining whether the abnormality of the battery pack. The battery pack according to an embodiment comprises: at least one battery cell; a microcomputer having an output terminal for reference voltage, a measurement terminal of a first voltage, and a measurement terminal of a second voltage, and controlling charging and discharging of the battery cell by detecting more than the reference voltage in the state of the first voltage and the second voltage; a voltage division part connected between the reference voltage and a ground to divide the reference voltage, and outputting the divided intermediate voltage to the microcomputer with the first voltage; and a voltage measurement part connected between the the output terminal for the first voltage and the ground, and outputting a diode forward direction voltage depending on temperature to the microcomputer with the second voltage. [Reference numerals] (110) Battery; (120) Charge switch; (130) Discharge switch; (140) Analog front-end(AFE) IC; (150) Micro computer; (160) Voltage division part; (170) Voltage measurement unit</p> |
