Supercapacitor module sizing

The sizing of a supercapacitor module consists of determining the number of elementary cells needing to be coimected in a series and/or in parallel to satisfy the 

Generally, a supercapacitor module is designed to provide a large amount of power for a veiy limited period of time (typically less than ten seconds). We can study the problem in two different, but closely linked, ways. The first is based on the power and the second uses the stored energy.

First, the load and supercapacitor voltages both float based on the battery voltage that is affected by its state of charge, and therefore limit exploitation of the power capability of the supercapacitor. In addition, the requirements of the supercapacitor module or cell voltage are defined by this same issue, in that the upper limit of the module voltage must match that of the battery. As a result, control over the module bank size becomes restricted. 

A supercapacitor module is sized according to a set of specifications established on the basis of the power required and the duration for which the module provides the power. The desigu method is illustrated in Figure 4.9. This method consists of ...
