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.

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 gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit mass or energy per unit volume than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.
These electrochemical type capacitors are small in size and can offer capacitance in tens, hundreds, or even thousands of Farad. They cannot only store a large amount of charge, but they
An energy storage application and a large capacitance value suggests supercapacitors should be investigated, but because the voltage is so large, series-parallel combinations are necessary.

Supercapacitors can be placed in series or in parallel. Due to the low voltage characteristics of a single supercapacitor cell, most applications require multiple cells in series to
Supercapacitor balancing methods prevent voltage overloads in series-connected supercapacitors and ensure longevity. The article details both passive and active balancing
Any capacitor put in series will increase the voltage rating of the capacitor. Keep in mind that supercapacitors are different from normal capacitors because of their very low ESR (Equivalent
Supercapacitors can be wired in series to form a higher voltage string, wired in parallel for additional capacitance or both, depending on the application. Eaton''s supercapacitors can be wired in series for
For applications where the supercapacitor needs to be charged to more than 2.5V or 2.7V, engineers are forced to connect multiple supercapacitors in series as the standard supercapacitor voltage is
