Summary:Provided is a system for battery entropy extraction through calorimetric measurement using a flexible heat flow sensor. The system for battery cell entropy extraction according to an embodiment of the present invention calculates entropy on the basis of temperature and voltage information, and comprises a thermo electric device (TED), which is flexible, can cover every surface of a battery cell, and serves as a heat flow sensor. Accordingly, entropy values can be extracted more accurately using the flexible heat flow sensor that can cover every surface of a battery cell. L'invention concerne un système d'extraction d'entropie de batterie par mesure calorimétrique à l'aide d'un capteur de flux de chaleur flexible. Le système d'extraction d'entropie de cellule de batterie selon un mode de réalisation de la présente invention calcule une entropie en fonction d'informations de température et de tension, et comprend un dispositif thermoélectrique (TED) qui est flexible, peut recouvrir chaque surface d'une cellule de batterie, et sert de capteur de flux de chaleur. Ainsi, des valeurs d'entropie peuvent être extraites plus précisément à l'aide du capteur de flux de chaleur flexible qui peut recouvrir chaque surface d'une cellule de batterie. 플렉시블 열류 센서를 이용한 열량 측정을 통한 배터리 엔트로피 추출 시스템이 제공된다. 본 발명의 실시예에 따른 배터리 셀 엔트로피 추출 시스템은, 온도와 전압 정보를 기반으로 엔트로피를 계산하는 추출 시스템에 있어서, 유연한 특성을 갖도록 형성되어, 배터리 셀의 모든 표면을 덮을 수 있도록 마련되어, 열류 센서 역할을 수행하는 TED(Thermo electric device);를 포함한다. 이에 의해, 배터리 셀의 모든 표면을 덮을 수 있도록 유연한 특성을 갖도록 형성되는 열류 센서를 이용하여, 보다 정확하게 엔트로피의 값을 추출할 수 있다.
