Zusammenfassung:	The present invention relates to a battery device capable of controlling a rapid change in battery temperature by a phase change material and a battery device operating method using the same to prevent overheating of the battery cell and to maintain the temperature of the battery cell at a predetermined level by controlling a rapid temperature change of the battery cell through a phase change material (PCM). According to the present invention, the battery device comprises: a battery unit including one or a plurality of battery packs, each of which includes one or a plurality of battery cells; a temperature control unit located in contact with the battery cell and including a phase change material (PCM); a temperature sensor unit including a battery cell temperature sensor for measuring the temperature of the battery cell; a voltage sensor unit including a voltage sensor for measuring the voltage of the battery pack; a current sensor unit including a current sensor for measuring the current of the battery pack; an analysis unit receiving data measured by at least one selected from the group consisting of the temperature sensor unit, the voltage sensor unit, and the current sensor unit to analyze whether the battery cell or the battery pack is operating normally and the state of charge (SOC); and a monitoring unit for displaying the information received from the analysis unit. 본 발명은 단수 또는 복수의 배터리 팩을 포함하고, 상기 배터리 팩은 각각 단수 또는 복수의 배터리 셀을 포함하는 것인 배터리부; 상기 배터리 셀에 접하여 위치하고 상변환 물질(phase change material, PCM)을 포함하는 온도제어부; 상기 배터리 셀의 온도를 측정하는 배터리 셀 온도센서를 포함하는 온도센서부; 상기 배터리 팩의 전압을 측정하는 전압센서를 포함하는 전압센서부; 상기 배터리 팩의 전류를 측정하는 전류센서를 포함하는 전류센서부; 상기 온도센서부, 전압센서부 및 전류센서부로 이루어진 군으로부터 선택된 1종 이상에 의해 측정된 데이터를 수신하여 상기 배터리 셀 또는 배터리 팩의 정상작동 여부 및 충전 상태(state of charge, SOC)를 분석하는 분석부; 및 상기 분석부로부터 수신한 정보를 표시하는 모니터링부;를 포함하는 배터리 장치에 관한 것이다. 본 발명은 상변환 물질(phase change material, PCM)을 통해 배터리 셀의 급격한 온도 변화를 제어함으로써, 상기 배터리 셀의 과열을 방지하고, 상기 배터리 셀의 온도를 일정 수준으로 유지할 수 있는 효과가 있다.
