Subject(s): | -Àrees temàtiques de la UPC::Informàtica::Automàtica i control -Fuel cells -Hybrid electric vehicles -Hybrid platforms powered by fuel cell and supercapacitor represent a powertrain with active state-dependent constraints -providing an adverse scenario for the energy management. In these platforms -the performance of the vehicle in terms of efficiency and power compliance is noticeably affected by the energy management strategy. This paper presents a novel energy management strategy based on the estimation of the future energy demand. The strategy aims for maintaining the state of energy of the supercapacitor between two limits -which are computed online using the states of the system. The performance of the proposed strategy is tested by simulation in a hybrid electric bus operated under real urban driving conditions. The results show improvements on hydrogen consumption and on power compliance compared to the widely reported Equivalent Consumption Minimization Strategy. Also -the results include the comparison with the optimal strategy obtained offline through Dynamic Programming. -Vehicles elèctrics híbrids -SuperCondensadors elèctrics -Piles de combustible |
