Energy Management System for Fuel Cell-Battery Vehicles Using Multi objective Online Optimization

An Energy Management system for fuel cell/battery vehicles manages and controls the consumption affects lifetime of powertrain system. This paper proposes a new System that is based on multi-objective online optimization technique. The proposed objective to minimize cost function composed four terms: actual consumption, two terms representing stresses lifetimes components (the cell battery), fourth term penalty deviation from desired SOC battery. minimization performed with no need prior knowledge driving cycle. couples frequency-decoupling-based technique split power demand among available sources relieve those sources. shows flexibility address multiple objectives can simply be deployed as real-time strategy. analytical derivation given, simulation results show effectiveness approach. A comparison between Dynamic-Programming-based System. achieves near-optimal solution without
