본 발명의 일 실시예에 따른 슬레이브 모듈은 배터리 셀의 전압, 전류, 및 온도 중 하나 이상에 관한 측정 값을 얻는 마이크로 컨트롤러 유닛; 상기 측정 값에 근거하여 상기 배터리 셀의 충전율 및 건강 상태 중 하나 이상을 포함하는 배터리 셀 상태를 추정하는 상태 추정 IC; 및 상기 배터리 셀 상태를 출력하는 입출력 단자를 포함하는 것을 특징으로 한다.

    The present invention relates to a slave module, a battery management system having the same, and a battery status estimation method. The slave module according to one embodiment of the present invention comprises: a microcontroller unit which obtains a measurement value regarding equal to or more than one out of a voltage, a current, and a temperature of a battery cell; a status estimation IC which estimates a battery cell status including equal to or more than one of a charge rate and a health status of the battery cell based on the measurement value; and an input/output terminal which outputs the battery cell status. An objective of the present invention is to provide the slave module which can reduce a manufacturing cost, the battery management system having the same, and the battery status estimation method.
