ES-Battery Direct Coupling Passive Control

Simulation studies through a directly coupled pairing of a supercapacitor (BCAP0310 P250) and lithium ion (Li-ion) battery (MP 176065) have also shown that under certain load profiles the supercapacitor demonstrated superior performance to the state-of-the-art Li-ion battery. Despite these inherent benefits, a theoretical analysis of a representative passive ES-bat-tery model [3] outlined the limitations arising from their direct coupling. [Pg.251]

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. [Pg.251]
