Title:
SYSTEM FOR BATTERY ENTROPY EXTRACTION THROUGH CALORIMETRIC MEASUREMENT USING FLEXIBLE HEAT FLOW SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/022431
Kind Code:
A1
Abstract:
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.
