Technical FAQs 4

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 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.

Why does a super capacitor charge at a constant voltage?

Eventually, the super capacitor voltage, and therefore the charging circuit’s operating efficiency, increases so the capacitor charges at the desired constant (fast or max) charge current, ICHG, until it reaches and remains at constant voltage (CV) regulation voltage, VREG.

How much current can a supercapacitor discharge?

Supercapacitors can be charged and discharged quickly, and the peak current is only limited by its internal resistance, and is not caused by a short circuit. In fact, it depends on the size of the capacitor monomer. For matching loads, small units can discharge 10A, and large units can discharge 1000A.
