An apparatus for alleviating the voltage drop of a battery according to an embodiment of the present invention includes a battery having battery cells; a sensing part which senses the battery and generates sensing information; a calculation part which computes the allowable torque of a motor by using the sensing information and calculates the prospective voltage of the battery by using the sensing information; and a determination part which controls the toque of the motor by using the prospective voltage and a reference voltage. According to the present invention, the voltage of the battery is stabilized by controlling the lowest voltage of the battery based on a low temperature and a low SOC test.

    본 발명의 일실시예에 따른 배터리 전압 강하 완화 장치는, 다수의 배터리 셀을 갖는 배터리; 상기 배터리를 센싱하여 센싱 정보를 생성하는 센싱부; 상기 센싱 정보를 이용하여 모터의 허용 토크를 계산하고, 상기 허용 토크 및 센싱 정보를 이용하여 상기 배터리의 예상 전압을 산출하는 계산부; 및 상기 예상 전압과 기준 전압을 이용하여 상기 모터의 토크량을 제어하는 판단부;를 포함하는 것을 특징으로 한다. 본 발명에 따르면, 저온 및 저SOC의 시험을 바탕으로 배터리의 최저 전압을 제어함으로써 배터리의 전압을 안정시킨다.
