Various degradation measures such as capacitance, equivalent series resistance, dissipation factor, and insulation resistance have been used to monitor the degradation state of capacitors. To capture the degradation behavior in a shorter time, several acceleration models are used to replicate the specific failure behavior.
However, the life estimation by the proposed model is far from accurate when compared to the experimental results, and the temperatures to which capacitors are subjected in the experiment are much higher than the maximum recommended operating temperature (category temperature) of the capacitors.
A capacitance degradation model is proposed where the model parameters are related to the capacitor at specific voltage and temperature conditions. The model parameters are a function of voltage and temperature and determined by fitting the curve to the experimental points at the applied aging test conditions.
Usually, the capacitance of a supercapacitor has a value in the range of Farads. The capacitance of a normal “ideal” capacitor ranges from sub micro- to hundreds of micro-Farads, which means that compared to the supercapacitor values, they store at least a million times more charge than the “ideal” capacitor.
