已经建立了一个简单的电气模型来描述超级电容器的行为作为混合动力汽车应用的频率，电压和温度的函数。电模型由14个RLC元件组成，这些元件是通过在商用超级电容器上应用电化学阻抗谱（EIS）从实验数据确定的。频率分析首次扩展到毫赫兹范围，以考虑漏电流和电极上的电荷再分布。对超级电容器充放电过程的仿真和实验结果进行了对比分析。在1 mHz至1 kHz、-20至60 ℃和0至2.5 V范围内，模型和EIS结果之间具有良好的相关性。（c）2006 Elsevier B. V.保留所有权利。
A simple electrical model has been established to describe supercapacitor behaviour as a function of frequency, voltage and temperature for hybrid vehicle applications. The electrical model consists of 14 RLC elements, which have been determined from experimental data using electrochemical impedance spectroscopy (EIS) applied on a commercial supercapacitor.The frequency analysis has been extended for the first time to the millihertz range to take into account the leakage current and the charge redistribution on the electrode. Simulation and experimental results of supercapacitor charge and discharge have been compared and analysed. A good correlation between the model and the EIS results has been demonstrated from 1 mHz to 1 kHz, from -20 to 60 degrees C and from 0 to 2.5 V. (c) 2006 Elsevier B.V. All rights reserved.
