A supercapacitor operates like a classic capacitor in that the discharge profile for a constant discharge current exhibits a linear decrease in voltage. Unlike a battery, the energy storage in a supercapacitor is electrostatic, so there are no chemical changes in the device, and charge and discharge operations are almost entirely reversible ...
The capacitor bank will potentially stay charged for years if the discharge load fails. Treat it as dangerous until you verify it's down to a safe voltage with an external trusted instrument. No jewelry on your hands or above the shoulders (necklaces etc). Long hair in a bun. The formula for the voltage on a capacitor being discharged is
Well...only until their potentials meet in the middle. Crazy Buddy's answer and related comments have made the point that you could indeed use a capacitor to charge a battery, but the amount of energy stored in capacitors is generally less than in batteries so it wouldn't charge the battery very much.
As others have said, the fact that the amount of energy being stored in a capacitor is a factor of the voltage squared makes having a bank of capacitors charged up to a high voltage seem appealing, though depending on the voltage level can be difficult to design around.
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.
Ultracapacitors provide the unique capability to be charged and discharged at the same rate. This is possible since the energy that is stored, is not a result of a chemical reaction. Therefore, the rated current of the cells are both for charge and discharge.
The voltage is V = Q/C V = Q / C which is 10,000 volts or so again. Even if you could charge it this much, it would be pretty bad to connect it to a 1.5-volt battery. To summarize, the charging is only good if the voltage is close to 1.5 volts but capacitors have vastly variable voltage that depends on the stored energy and/or charge dramatically.

All you need to charge a battery from a capacitor is to have more voltage charged on the capacitor than the voltage of the battery. The size will only affect how much time the capacitor will charge the battery. If you could charge the …
It should be selected to discharge the bank C2 down to a safe voltage of 48VDC in a "reasonable" time - say 10 minutes. The C2-R2 time constant would then be in the ballpark of 1-2 minutes. Fuses F1 and F2 are important. F1 protects the capacitor bank from destructive discharge (a.k.a. a big bang) should the DC link become shorted. F2 protects ...

4 · The leakage resistance R leak is not a physical parameter but simulates the self-discharge phenomena that occur inside the SC when it is not connected to a load. Self-discharge can be measured by charging the SC at a certain voltage (usually the rated voltage) and reaching a certain charge value. There are not many techniques in the literature.

With examples and theory, this guide explains how capacitors charge and discharge, giving a full picture of how they work in electronic circuits. This bridges the gap between theory and practical use. Capacitance of a capacitor is defined as the ability of a capacitor to store the maximum electrical charge (Q) in its body.
