leads to one side of the capacitor. Connect the working electrode lead (and working sense es a current given by=I is current= = in amperes, and s the scan rate of the voltage ramp.Voltage scan rates for super-capacitor testing ar usually between 0.1 mV/s and 1 V/s. Scan rates at the lower end of this range allow slow processes to occur, bu
Supercapacitors have such large capacitance values that standard measuring equipment cannot be used to measure the capacity of these capacitors. Capacitance is measured per the following method: Charge capacitor for 30 minutes at rated voltage. Discharge capacitor through a constant current load. Measure voltage drop between V1 to V2.
We are going to be examining three parameters of super capacitors. Capacitance Value, Equivalent Series Resistance (ESR) and Leakage Current / Self Discharge. I will show you several ways to test each parameter and let you know what worked well for me. Why Is ESR Important?
A +-20% 500 Farad cap could actually be a 400 Farad cap even before it starts to degrade from age and use. So we know the range of acceptable values for our capacitor. In my case I have six 100 Farad capacitors rated at +-20%. This gives me an acceptable value range of 80 to 120 Farad.
Red is the fastest scan rate; purple is the slowest. Electrochemical Impedance Spectroscopy (EIS) is the preferred method for measuring ESR of super-capacitors. EIS also can measure capacitance and capacitor non-ideality. For basic information on EIS, see Gamry’s application note at :
