Abstract: In this paper, the thermal behavior of supercapacitor cells during charging and discharging under different working conditions is studied, which provides a theoretical basis for the use of supercapacitors. The results show that when the ambient temperature is 25℃, the current changes linearly. The highest internal temperature of the monomer reaches 25.31℃(298.46 K); In 3 times rated current cycle charging and discharging conditions, after 15 cycles of charging and discharging, the highest temperature inside the capacitor monomer reaches 55℃ (328K), charging and discharging process. After 30 cycles, the highest temperature inside the capacitor unit reached 82℃ (355 K).

Key words: supercapacitors, thermal behavior, simulation analysis
