摘要
以超级电容器数学模型为研究对象,考虑超级电容器的充放电特性,对其等效模型进行研究,提出一种基于超级电容器充放电特性的动态等效电路模型。在该模型中,超级电容器的等效串并联内阻随电容器两端电压和电流动态变化。通过对比超级电容器进行充放电实验数据,结果表明该模型预测的充放电电压与实验值吻合。
Based on charging and discharging characteristic, the paper studied the supercapacitor equivalent model and put for-ward a dynamic equivalent model. In the new model, the equivalent series resistance and parallel resistance vary with voltage and current of supercapacitor. Through charge and discharge experiment, it indicates that the charge and discharge voltage pre-dicated by new model agree well with experimental values.
