Plug and play your way to balancing supercapacitors

摘要

Supercapacitors are unique because they can work in conjunction with or as an alternative to batteries in applications needing many rapid charge/ discharge cycles, and they are popular in applications such as short-term energy storage, regenerative braking, and static RAM memory backup. But balancing a supercapacitor in a design involves more than connecting a few wires. When a supercapacitor has an operating voltage of 2.5-2.7 V, most applications use an array of devices connected in series for higher voltage.
