Feb 06, 2013 · What is Supercapacitor A supercapacitor or ultracapacitor is an electrochemical capacitor that has an unusually high energy density when compared to common capacitors. The use of an aqueous electrolyte limits the voltage to about 1V while electrolytes based on organic solvents allow dissociations voltages up to 2. On the other hand the thermal model is needed to predict the surface temperature of the battery cell for operating of the cooling and heating system when required. The electrical model is required for prediction of the battery behavior such as energy, power, internal re‐ sistance, life cycle and energy efficiency.
