Technical FAQs 4
How do you charge a super capacitor?
Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
Can a super capacitor be discharged down 0 V?
All trademarks are the property of their respective owners. Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current.
How long should a supercapacitor be charged?
In order to get a realistic measurement of leakage or self dis-charge current the supercapacitor must be charged for in excess of 100 hours, this again is due to the capacitor construction. The supercapacitor can be modeled as several capacitors connected in parallel each with an increasing value of series resistance.
Why does a supercapacitor need a small current?
supercapacitor has a high internal resistance, and a small current is needed to keep the charge on the supercapacitor. Leakage current is a charge current measured from the pin-to-pin voltag across a charge resistor when the supercapacitor is ch rged for many hours and while the supercapacitor is on charge. Figure
