How to measure supercapacitor leakage current? Just 4 steps, easy messed up

Supercapacitors have very high resistance values, but there is still leakage current. The leakage current is equivalent to the charging current required to maintain the supercapacitor at a predetermined voltage value. The measurement of the leakage current will be affected by temperature, device charging voltage and its aging conditions.

 

The following is a step to measure the leakage current of a supercapacitor by using a multimeter with a high resistance and internal resistance to test the electrical circuit diagram:

1. Charge at a normal temperature (25°) for 72 hours at the rated voltage of the supercapacitor.

2. Disconnect switch SW (about 10 minutes) to stabilize the supercapacitor temperature and internal structure.

3. Close the switch and measure the voltage across the resistor (a resistor is known for easy calculation) with a multimeter with a high internal resistance.

4. Leakage current DCL = V/R.
