Can super farad capacitors be charged continuously

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 charged infinitely?

We have also found that for some super-capacitors one cannot pump infinite current to charge a super-capacitor because the effective parallel resistance reduces as one try to pump large current and therefore charging these capacitors to a given desire voltage may not be possible.

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 to charge a supercapacitor to a peak voltage?

Here, one can charge the supercapacitors to the peak voltage, Vp =3.5 V, by pumping 1Amp constant current. Another option is to pump high current and charge the capacitor up to a certain lower voltage (≤3.5 V) and then drop the current to charge the capacitors to some higher voltage and keep doing it till we get 3.5 V.
