Summary:A battery entropy extraction system through calorimetric measurement using a flexible heat flow sensor is provided. The battery cell entropy extraction system according to an embodiment of the present invention, as an extraction system which calculates entropy based on temperature and voltage information, includes a thermo electric device (TED) formed to have a flexible characteristic, provided to cover all surfaces of a battery cell, and serving as a heat flow sensor. Accordingly, an entropy value can be more accurately extracted by using the heat flow sensor formed to have a flexible characteristic so as to cover all surfaces of the battery cell. 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.
