Super capacitor over voltage
There is a minimum load requirement and it''s possible that the capacitor was charged to a higher voltage because there was only the capacitor as a load. By my calculation, a 500F capacitor

Supercapacitors (SC) usually operate at low voltages of around 2.7 V. In order to reach higher operating voltages, it is necessary to build a cascade of serial connected SC cells.
When supercapacitors are used in series, there is a problem of voltage balance between the cells. The simple series connection will cause overvoltage to one or several cell capacitors, which
Supercapacitor A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits. It bridges the
When a capacitor exceeds its working voltage, several mechanisms can lead to failure. The nature and severity of the consequences depend largely on the type of capacitor, the extent of
The circuit below solves this over-voltage problem by balancing the string with a voltage limiting circuit across each capacitor. The circuit diverts charging current around each part, when the voltage
This means I can not guarantee the voltage feeding the supercap is within the capacitor''s limits, so I have to make a circuit which protects the supercap against dangerously high voltages.
Novel Circuit Design Offers Insight on Over-Voltage Problem that Jeopardizes Cell Life and Provides Solution on How to Implement Automatic Leakage Current Equalization
In this article, we will explore the potential consequences of overvoltage on capacitors, highlighting the risks involved and discussing strategies to mitigate them.
One simple way of protecting against reverse voltage is to add a diode across the capacitor, configured so that it is normally reverse bias. By using a suitably rated zener diode in place of a standard diode
