Energy Analysis of Hybrid Power Source During Vehicle Motion

This paper proposes a perfect energy source provided by a polymer electrolyte membrane fuel cell (PEMFC) as the main power source and a storage device: battery and super-capacitor, for modern distributed generation system, particularly for future fuel cell vehicle applications. The energy in hybrid systems is balanced by the dc bus regulation in dependence to the drive cycle. A super-capacitor module, as a high dynamic and high power density device, functions for supplying energy to regulate a dc bus. A battery module, as a high energy density device, operates to supply energy to the super-capacitor bank in order to keep it charged. The control strategy is used to determine the real-time optimal power distribution by simple minimization.
