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.

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.

When there is no current, there is no (IR) drop, and so the voltage on the capacitor must then equal the emf of the voltage source. This can also be explained with Kirchhoff''s second rule (the loop rule), discussed in Kirchhoff''s Rules, which says that the algebraic sum of changes in potential around any closed loop must be zero.
