摘要: 本文对超级电容单体在不同工况下的充、放电时的热行为进行了研究,为超级电容的使用提供理论依据,结果表明:环境温度为25℃时,在电流呈线性变化的工况中,单体内部最高温达到25.31℃(298.46 K);在3倍额定电流循环充放电工况中,充、放电过程循环15次后,电容单体内部最高温达到55℃(328 K),充放电过程循环30次后,电容单体内部最高温达到82℃(355 K)。

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
