Energy Storage Using Supercapacitors: How Big is Big Enough?
In a power backup or holdup system, the energy storage medium can make up a significant percentage of the total bill of materials (BOM) cost, and often occupies the most volume. The key to optimizing a solution is a careful selection of components so that holdup times are met, but the system is not overdesigned.
Supercapacitor
A supercapacitor (also called an ultracapacitor or electrochemical capacitor) is a type of electrochemical energy storage device. It is superficially similar to a conventional capacitor in that it consists of a pair of parallel-plate electrodes, but different in that the two electrodes are separated by an electrolyte solution rather than a solid dielectric.
