This handy tool calculates the time it takes to discharge a super capacitor from an initial to a final voltage value under constant current and resistor load conditions 4. 1 What is a super capacitor? Enter the following parameters. Supercapacitors, also known as ultracapacitors and electric double layer capacitors (EDLC), are capacitors with capacitance values greater than any other capacitor type available today. Supercapacitors are breakthrough energy storage and delivery devices that offer millions of times more. . This calculator determines timekeeping operation using a super capacitor (supercap) based upon starting and ending capacitor voltages, discharge current, and capacitor size. Bt (seconds) = [C (Vcapmax - Vcapmin)/Imax] This formula is valid for constant current only. 5V 4F super-capacitor very similar to the one in the image. It bridges the gap between electrolytic capacitors and rechargeable batteries.
