This paper treats the sizing and Energy Management (EM) of Fuel Cell/battery source for automotive application. The fuel cell system is used as the main source and batteries pack is the auxiliary one. A bidirectional DC/DC converter is used to connect the batteries to the DC bus and a DC/DC boost converter associates the fuel cell stack with DC link. A sizing algorithm is developed to determine the...
This paper presents an optimal energy management of a Fuel Cell/Ultra-Capacitor power source based on Ant Colony Optimization metaheuristic for vehicular applications. First, the modeling of the Fuel Cell/Ultra-Capacitor hybrid source which presents a better dynamic performance and energy efficiency is described. Then, the optimal control problem formulation based on the Ant Colony Optimization algorithm...
The credentials of fuel cell (FC) as an alternative source for electric vehicle are not encouraged by many due to its high cost and slow dynamics. Moreover, due to slow dynamics of FC dominated by temperature of fuel delivery system, fast load demand will cause a large voltage drop in a short time, which is recognized as a fuel starvation phenomenon. To overcome this problem, an energy storage system...
